When incarcerated in an inguinal hernia, a Meckel diverticulum is called a Littr hernia. Upper gastrointestinal bleeding has several different etiologies that vary by location of bleeding and age of patient: in newborns to 1-mo-olds, it can be related to milk protein sensitivity, coagulopathy, stress gastritis or ulcer, vitamin K deficiency, swallowed maternal blood, or vascular anomaly; in 1- to 2-mo-olds, to stress gastritis or ulcer, acid-peptic disease, gastrointestinal duplications, gastric or esophageal varices, duodenal or gastric webs, bowel obstruction, or vascular anomaly; and in children older than 2 mo and adolescents, to acid-peptic disease, caustic ingestion, bowel obstruction, Crohn disease, Dieulafoy lesions, or Mallory-Weiss tears (58). The RAdiation Dose Assessment Resource website. This tissue normally is reabsorbed before birth. Inflammatory bowel diseases such as Crohn disease, a diverticular abscess, and hypervascular neoplasms may also make interpretation difficult (7,20). Meckel's Diverticulum (MD) was first reported in 1598 by a German surgeon named Fabricius Hildanus who observed a diverticulum occurring in the distal part of the ileum. This is presumed due to the cimetidinemediated retention of pertechnetate in the gastric mucosa. Once again, SPECT/CT should be performed with a CT amperage appropriate for patient size and age (34,61). Relying on all 4 criteria to positively diagnose a gastrointestinal bleed will often clarify whether the patient has active gastrointestinal bleeding or another process masquerading as bleeding. Definitions of Various Types of Gastrointestinal Bleeding (8), Causes of Interference with Erythrocyte Radiolabeling, Leading to Free 99mTc-Pertechnetate (915). Ultratag RBC package insert. [QxMD MEDLINE Link]. [16], When a Meckel diverticulum is incidentally discovered at laparoscopy or laparotomy, the surgeon must decide whether to resect. The SNMMI procedure standard/EANM practice guideline for gastrointestinal bleeding scintigraphy 2.0, Diagnosis of gastrointestinal bleeding: a practical guide for clinicians. [2] ; when it does, gastric mucosa accounts for 50%. Upper bleeding generally presents with hematemesis (either red or coffee-ground emesis) or melena. The risk of complications ranges from 4% to 25% in various studies. J Comput Assist Tomogr. Heart (H), vascular structures (V), liver (L), spleen (S), and penis (P) are labeled. Meckel's diverticulum is the congenital persistence of all or part of the omphalomesenteric duct , also referred to as the vitelline duct or yolk stalk . Gastric mucosa is the mucous membrane layer of the stomach. Imaging for 60 min can be performed when clinical suspicion is high and the initial 30-min images are negative (61). Due to the fact that it is rarely the source of illness in the surgical patients our treatment of this entity is based upon anecdotal reports and . The erythrocyte labeling techniques are summarized in Table 3. The radionuclear imaging procedure, also known as Meckel's scan or scintigraphy, uses a larger field-of-view (LFOV) gamma camera to detect the concentration of radioactive substances (radioisotopes such as technetium-99m pertechnetate, injected intravenously) in ectopic gastric mucosa in the diverticulum. Each of them images the vascular compartment, although some tracers stay in the vascular compartment longer than others. American College of Radiology website. Learn about the early signs of pregnancy and when to take a pregnancy test. Nuclear medicine specialists use advanced imaging techniques such as CT scans to diagnose diseases and monitor therapies. Michal Lotem, Ayala Hubert, Olga Lyass, Michael A. Goldenhersh, Arieh Ingber, Tamar Peretz, Alberto Gabizon. [26] Primary outcomes were length of stay (LOS), readmission rate, and 30-day mortality; secondary outcomes included operating time, anesthesia time, postoperative complications, and reoperation rate. Examples of bleeding at these 3 major sites are illustrated in Figures 35. Sign In to Email Alerts with your Email Address. Complications manifest as the following: In an excellent population-based study by Cullen et al that covered patient data over a period of 42 years, the lifetime risk of developing a complication that required surgery was estimated to be 6.4%.

After recovery, resection of Meckel's diverticulum generally has no effect on gastrointestinal functioning or nutrition. Multiple parenchymal liver metastases as the first site of recurrent ovarian carcinoma: a case report and review of the literature. A lateral image of the pelvis can be helpful to exclude the presence of a rectal bleed and clarify what may be only physiologic penile activity. Laparoscopy and complicated meckel diverticulum in children. The prevalence of lower gastrointestinal bleeding increases by more than 200 times between the ages of 30 and 90 y (7). This is a condition that occurs as a baby is developing during pregnancy, in which a small pouch (or sac) forms in the ileum (the lower end of the small intestine). In addition to clarifying unclear sites of radiolabeled erythrocytes, SPECT or SPECT/CT has been applied to further define the location of the bleedinguseful in therapeutic planning, particularly angiography or surgery. Meckel's diverticulectomy: a multi-centre 19-year retrospective study. The most common congenital cause of a Meckel diverticulum is failed closure of the omphalomesenteric duct, most commonly in the distal ileum. Laparoscopic diverticulectomy or laparoscopic-assisted resection of symptomatic Meckel diverticulum in children? 62.1).Paired vitelline arteries arise from the dorsal aorta and run parallel to the omphalomesenteric duct to supply the . With both approaches, Meckel's diverticulum is resected, the ulcerated area is identified, and the bleeding is stopped. When a patient presents with painless lower GI bleeding, Meckel diverticulum should always be suspected. National Cohort Study: What Is the Cancer Risk in Patients With Diverticular Disease? Karadeniz Cakmak G, Emre AU, Tascilar O, Bekta S, Uan BH, Irkorucu O, et al. . After the patients erythrocytes have been labeled and readministered, a dynamic acquisition of the abdomen and pelvis is performed with a 1282 matrix. Thirunavukarasu P, Sathaiah M, Sukumar S, Bartels CJ, Zeh H 3rd, Lee KK, et al. Abdominal pain. Learning Objectives: On successful completion of this activity, participants should be able to describe (1) diagnostic uses of gastrointestinal bleeding scintigraphy; (2) proper methodology for performing the procedure; (3) the importance of correlative and hybrid imaging; (4) interpretive criteria to make a clinical diagnosis; (5) special considerations in children; and (6) imaging of Meckel diverticula. Complications from Meckel's diverticulum can develop at any age, and it is estimated that there is a 4 percent to 25 percent lifetime risk of complications occurring. Is SPECT/CT with a hybrid camera useful to improve scintigraphic imaging interpretation? RADAR medical procedure radiation dose calculator and consent language generator. In this redox reaction, Tc7+O4 is the oxidizing agent and the stannous ion (Sn2+) is the reducing agent (11,20,21). Meckel's diverticulum is a congenital malformation in the lower part of the ileum ( Figure 1 ). Approximately 21 of every 100,000 adults in the United States require hospitalization for lower gastrointestinal bleeding annually (4). Shopping for over-the-counter medications can be confusing, but your local pharmacist can help. However, in some individuals, the secretion of acid by Meckel's diverticulum may cause peptic ulcers in the small intestinal lining. 2007 Feb 21. [9] This isotope, administered intravenously, is readily taken up by the gastric mucosa. Other lesions with ectopic mucosa can include enteric duplications, gastrogenic cysts, and duplication cysts (63). Given its distribution in periphery of abdomen (arrows), focus is typical of large-bowel bleed originating in descending colon.

Brungardt JG, Cummiskey BR, Schropp KP. Quantification and predictors of prostate position variability in 50 patients evaluated with multiple CT scans during conformal radiotherapy. This is a PDF-only article. Similarly, salivary activity can be reduced by a host of medical conditions, medications, or prior therapies (e.g., Sjgren syndrome, Parkinson disease, antihistamines, diuretics, antipsychotics, chemotherapy, prior surgical disruption, external-beam radiation therapy, and 131I-sodium iodide therapy). The action you just performed triggered the security solution. An upper GI series with small-bowel follow-through also detects a diverticulum. Pharmaceuticals that Augment Visualization of Meckel Diverticulum (11,58). Pegylated liposomal doxorubicin (doxil): reduced clinical cardiotoxicity in patients reaching or exceeding cumulative doses of 500 mg/m2. SNMMI designates each JNM continuing education article for a maximum of 2.0 AMA PRA Category 1 Credits. Radiography of the abdomen may indicate an ileus or frank stepladder air-fluid levels, as observed in dynamic intestinal obstruction. J Pediatr Surg. A Meckel's scan can help identify this abnormal tissue. Patients may also present with weakness and anemia and may have a history of self-limiting episodes of intestinal bleeding. In light of the significant mortality, timely diagnosis and evaluation are critical, as emergent intervention may be needed. (See the image below.). When a fistula is present, intestinal mucosa may be identified on the skin. False-Positive Results on Meckel Scanning (11,58). Let us know if this information is out of date or incorrect. Meckel's diverticulum is often encountered incidentally during laparotomy and is infrequently a cause of morbidity and mortality in the surgical patients. [QxMD MEDLINE Link]. Rectal bleeding requires a systematic approach to evaluation. GIBS is preferred in the pediatric population because of the lower absorbed radiation dose, and CTA should be avoided (60). [20] Intestinal resection was associated with a slightly longer operating time. found that grading the intensity of bleeding may be helpful in predicting angiographic positivity (44). Acute gastrointestinal bleeding: value of MDCT. Soltero MJ, Bill AH. Benjamin Nisman, Joel Lafair, Norman Heching, Olga Lyass, Mario Baras, Tamar Peretz, Vivian Barak.

Insights from a population-based epidemiological study and implications in surgical management. [QxMD MEDLINE Link]. [Full Text]. Care must be taken to ensure that each patient receives back his or her own radiolabeled blood product. The symptom most commonly seen in young children is painless rectal bleeding. Perforation of the inflamed diverticulum leads to peritonitis. Localizing the main arterial distribution is helpful when planning angiographic intervention. In preparation for the examination, the patient should fast for 34 h for best sensitivity, although this is not required (64). 53 (3):493-508. nuclear medicine study, payment may be made for the agent under the appropriate code for the radiopharmaceutical administered. A portion of small intestine may also twist around an anchored Meckel's diverticulum. Society of Nuclear Medicine. Comparison of Whole-Body Absorbed Radiation Dose Evaluated by GIBS vs. CTA (56,72). McKay R. High incidence of symptomatic Meckel's diverticulum in patients less than fifty years of age: an indication for resection. All these radiopharmaceuticals assist in compartmental localization. As a small molecule with a single negative charge, pertechnetate is secreted into the stomach as well as any ectopic gastric mucosa. Some work has suggested a prognostic benefit to delayed GIBS (27). These occur in up to 10% of patients and consist of fistulas, sinuses, cysts, and fibrous bands between the diverticulum and the umbilicus. found that positive GIBS within 12 min of scanning correlated with a positive angiogram (40). Meckel's diverticulum is a congenital (present at birth) outpouching or bulge in the lower part of the small intestine. [1] As a congenital anomaly, it is a true diverticulum that includes all three coats of the small intestine. A study of 202 cases of diseased Meckel's Diverticulum found in King County, Washington, over a fifteen year period. Technetium-99m pertechnate radioisotope scanning. Diagnosis of a bleeding Meckel diverticulum is established by means of technetium-99m (99mTc) pertechnetate radioisotope scanning. If it causes symptoms, Meckel's diverticulum can be repaired with surgery. The condition is named after German anatomist Johann Friedrich Meckel, who first described the condition in 1809. It is possible that you used an outdated or expired MedicineNet link or you [1] A European multicenter retrospective study by Baltes et al examined the use of small-bowel capsule endoscopy (SBCE) in 69 patients with Meckel diverticulum (median age, 32 y; male-to-female ratio, 3:1). Buy Abstract Administration of cimetidine prior to pertechnetate imaging in two patients with Meckel's diverticulum resulted in demonstrating the abnormality with unusual clarity. [4] As a result, they advocated diverticulectomy for asymptomatic disease even in the older age group. Prompt performance of GIBS, early time to positivity on GIBS, relative intensity of activity, and prompt performance of angiography subsequent to GIBS were found to lead to a positive angiogram by Lee et al. Example of bleeding originating from branch of inferior mesenteric artery. A Meckel scan assists in localizing the abnormal tissue in preparation for surgical removal. Other techniques for labeling red blood cells with greater efficiency were developed later, but the practice of evaluating gastrointestinal bleeding with scintigraphic techniques had already become established in clinical practice. [QxMD MEDLINE Link]. It frequently contains heterotopic tissue An epidemiologic, population-based study. 3333 Burnet Avenue, Cincinnati, Ohio 45229-3026. Digital subtraction has been found helpful in this setting (7). Intraoperative photograph of Meckel diverticulum. This is known as segmental volvulus and is associated with compromised blood supply and intestinal obstruction. Typical imaging appearance of Meckel diverticulum. The majority of studies require the patient to be injected with a radioactive isotope. Correlation of toxicity with pharmacokinetics of pegylated liposomal doxorubicin (Doxil) in metastatic breast carcinoma. Looking for something else? When referencing appropriateness criteria for lower gastrointestinal bleeding, both GIBS and CTA are ranked similarly according to the American College of Radiology (50). There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. Gezer H, Temiz A, nce E, Ezer SS, Hasbay B, Hisnmez A. Meckel diverticulum in children: Evaluation of macroscopic appearance for guidance in subsequent surgery. If a dual-head -camera is used for evaluation, acquiring the images with both camera heads may enhance visualization of a rectal bleed (7). Meckel's diverticulum can also cause intestinal obstruction. Other physiologic activity can occasionally confuse the interpreter; this activity is usually fixed. Focus crosses midline several times and thus is most compatible with small-bowel bleed. Yale New Haven Hospital Preparation for this Exam: Nafisa K Kuwajerwala, MD is a member of the following medical societies: American College of Surgeons, American Society of Breast Surgeons, American Society of Breast DiseaseDisclosure: Nothing to disclose. Epidemiology Gastrointestinal bleeding scintigraphy performed with 99mTc-labeled autologous erythrocytes or historically with 99mTc-sulfur colloid has been a clinically useful tool since the 1970s. 2016 Jul. The diverticulum may also form the lead point of an intussusception and cause obstruction. [QxMD MEDLINE Link]. The CT slices are quite thin, on the order of 12 mm (49). Given this disagreement, it is uncertain how well GIBS performs for surgical planning in all centers. A systematic review. A diverticulum is an out-pouching, or small pocket, in the wall of the large intestine. Lower gastrointestinal bleeding originates distal to the ligament of Treitz and is fairly common, accounting for approximately 21% of gastrointestinal bleeding overall (6) but is usually self-limited. The incidence of false-negative results is high, especially in adults; therefore, a negative scan finding does not exclude a Meckel diverticulum. Pitfalls in detection of acute gastrointestinal bleeding with multi-detector row helical CT. Azmath Mohammed, MD Resident Physician in General Surgery, Beaumont Health System The diagnosis of bowel obstruction due to Meckel diverticulum may not be established preoperatively. Occasionally it may also be seen as a cyst, raising a different differential diagnosis of intestinal duplication which however is said to have regular margins 2. Scintigraphy is indicated for evaluation of overt gastrointestinal bleeding. These ulcers can bleed or perforate (rupture), causing intestinal waste products to leak into the abdomen. Physicians should claim only credit commensurate with the extent of their participation in the activity. [QxMD MEDLINE Link]. Olga Lyass, Beatrice Uziely, Rami Ben-Yosef, Dinah Tzemach, Norman I. Heshing, Michal Lotem, George Brufman, Alberto Gabizon, Doxil (Caelyx): an exploratory study with pharmacokinetics in patients with hormone-refractory prostate cancer, Ayala Hubert, Olga Lyass, D Pode, Alberto Gabizon. The recommended administered activity is based on the European Association of Nuclear Medicine pediatric dosage card, which uses a baseline activity of 56 MBq multiplied by a weight-based factor and a minimum administered activity of 80 MBq (7,59). In complicated cases, the diverticulum must be resected. [11, 12, 13], In a study that included 21 pediatric patients with bloody diarrhea, Qi et al found double-balloon enteroscopy (DBE) to be a potentially useful tool for diagnosing Meckel diverticulum and guiding subsequent minimally invasive treatment. Accurate localization can help to streamline therapy and achieve an earlier therapeutic response. Meckel's Scan. Areas of free pertechnetate seen on scintigraphic images include the stomach, salivary glands, thyroid gland, and choroid plexus (29). Because the omphalomesenteric duct may be attached to the abdominal wall by a fibrotic band, a volvulus of the small bowel around the band may occur. 2014 Oct-Dec. 18 (4):[QxMD MEDLINE Link]. Scintigraphic imaging of gastrointestinal bleeding remains important in nuclear medicine. Meckel . The variation in sensitivity is likely related to the lack of a gold standard, but detection rates clearly increase when the study is performed as intendedwhen the patient is actively bleeding. [19, 21, 22, 23] With advances in technology, minimally invasive therapeutic interventions, such as intracorporeal resection or laparoscopic-assisted extracorporeal resection, Human embryos initially have convex umbilical loops of primitive gut that communicate freely with the yolk sac through the omphalomesenteric duct. The first page of the PDF of this article appears above. Drugradiopharmaceutical drug interactions. Cisplatin-induced non-convulsive encephalopathy. Imaging is generally performed for 2030 min with 99mTc-sulfur colloid, decreasing the opportunity to visualize the classically intermittent lower gastrointestinal bleed. Before initiation of scanning, it is important to learn more about the patient and the patients symptoms. In other countries, 99mTc-human serum albumin diethylenetriaminepentaacetic acid is used for the diagnosis of gastrointestinal bleeding (19). It is considered the most common structural congenital anomaly of the gastrointestinal tract. Some people are born with this irregularity in their small intestine. Find out which medical conditions are ranked as the most painful, according to experts. This abnormality, called a Meckel's diverticulum, is fairly common. All of these allow for treatment planning and risk stratification (8). Find Continuing Care Retirement Communites. 1996-2021 MedicineNet, Inc. All rights reserved. The current techniques and interventions have been described in this review. Water and hyperdense oral contrast agent are avoided. Indications: To establish the presence of Meckel's diverticulum. A Meckel's diverticulum normally does not cause any symptoms, but rarely can cause bleeding into the intestine. Infrequently, a tumor arising in the wall of the diverticulum may form the lead point for intussusception. Hosn MA, Lakis M, Faraj W, Khoury G, Diba S. Laparoscopic approach to symptomatic meckel diverticulum in adults. [4]. Division of Nuclear Medicine Procedure / Protocol _____ MECKEL'S DIVERTICULUM STUDY CPT CODE: 78290 UPDATED: APRIL 2010 _____ Indications: To establish the presence of Meckel's diverticulum. 2014 Sep. 42 (3):163-9. 1976 Aug. 132 (2):168-73. See all conditions on Dr. Lyass'. 99mTc-pertechnetate is the radiopharmaceutical of choice as it localizes to gastric mucosa. Camarillo California Gastroenterologist Doctors physician directory - Learn about duodenal diverticulum (extramural and intramural) causes, symptoms, complications (gallstones, pancreatitis), diagnosis, and treatment options. In early fetal life, the dorsal portion of the yolk sac gives rise to the primitive midgut, and the omphalomesenteric duct connects the ventral portion of the yolk sac to the developing small intestine (Fig. Are you wondering if you might be pregnant? For these reasons, multiple studies have found 99mTc-erythrocytes to be superior (1618). Upper and lower gastrointestinal bleeding require different clinical approaches, but although each has its usual signs the source of bleeding can be difficult to distinguish clinically. Postvoiding images or a urinary catheter can be helpful should the diverticulum be obscured by excreted activity in the urinary bladder. Understanding clinical descriptions of gastrointestinal bleeding such as overt or occult is helpful in elucidating patient history from our clinical colleagues (Table 1) (8). 2007 Mar. GIBS will detect a bleeding rate of 0.050.2 mL/min (3,37). Always consult with your health care provider to make an informed decision. Absolute indications for resection in Meckel diverticulum are hemorrhage, intestinal obstruction, diverticulitis, and umbilicoileal fistulas. Cureus. Occult bleeding identified by guaiac fecal testing is not an appropriate indication: the microscopic blood; slow, intermittent bleeding; or low-volume blood identified in stool is below the scintigraphic detection limit (7). SPECT SPECT/CT CTA pediatric GI bleeding by age Meckel's diverticulum It was in 1977 that Alavi et al., at the University of Pennsylvania, originally described evaluating gastrointestinal bleeding with scintigraphic methods using 99m Tc-sulfur colloid ( 1 ). JSLS. If you are Dr. Lyass and would like to add insurances you accept, please update your free profile at Doximity. Heterotopic tissue, including gastric mucosa and pancreatic tissue, is . This compilation of top pharmacist-recommended over-the-counter medicines and health products may make your next trip to the drugstore easier. The high level of background activity in the liver and spleen can obscure upper-gastrointestinal bleeding sources. This article reviews the history of the techniques, the different methods of radiolabeling erythrocytes, the procedure, useful indications, diagnostic accuracy, the use of SPECT/CT and CT angiography to evaluate gastrointestinal bleeding, and Meckel diverticulum imaging. False-positive results can occur from intussusception, volvulus, abscess, appendicitis, neoplasm, angiodysplasia, Crohn disease, ulcerative colitis, or other forms of colitis (6670). It is the most common congenital abnormality of the gastrointestinal tract, occurring in 1% to 3% of the population. Focus of increasing intensity is identified in upper abdomen, moves in anterograde fashion, and conforms to bowel. 13 (7):1141-3. Focus of increasing intensity is identified in left upper quadrant and shows anterograde movement. While symptoms of infection and blockage generally occur before adolescence, they can appear at any time in life and can cause mild to severe abdominal pain and discomfort. [9]. described diagnosing and localizing gastrointestinal bleeding with 99mTc-erythrocytes (3). Additional surgical considerations include the following: Principles of surgical treatment include the following: All procedures may be carried out either by handsewn technique or by stapling, depending on the preference of the surgeon. Take control of your mental health with these active ways to fight depression. Dr. Lyass' office is located at The sensitivity of GIBS has been reported to be 93% and the specificity 95% (16,17), although some investigators have cited lower rates (38,39). Table 6 provides more information on gastrointestinal and nongastrointestinal causes of false-positive results on Meckel scans. 6) (11,20). All have one thing in common: use of a redox reaction (Fig. Rationale: While a Meckel's diverticulum occurs in 1.5-3% of population, clinical symptoms appear in only 25-30% of these patients. The omphalomesenteric duct incompletely regresses to form a blind pouch at the antimesenteric border of the gut. False-positive results are observed in patients with intussusception, volvulus, obstruction of the small intestine, acute appendicitis, carcinoid of the appendix, or carcinoma of the cecum. Is There Still a Role for Tubal Surgery in the Modern World of IVF? Choi SY, Hong SS, Park HJ, Lee HK, Shin HC, Choi GC. Evaluation of Tissue Polypeptide Specific Antigen, CYFRA 21-1, and Carcinoembryonic Antigen in Nonsmall Cell Lung Carcinoma Does the Combined Use of Cytokeratin Markers Give Any Additional Information? Rationale: Meckel's diverticulum is the vestigial remnant of the omphalomesenteric duct and represents the most common congenital anomaly of the gastrointestinal tract, with an incidence of 1%- 3% in the general population. Special pictures are taken after a medicine is injected into a vein. Enter multiple addresses on separate lines or separate them with commas. Surgical management of Meckel's diverticulum. This can result in a serious abdominal infection called peritonitis.

Prognostic factors for survival in metastatic breast cancer during first-line paclitaxel chemotherapy. You are being redirected to 73 (3):271-5. ACR appropriateness criteria: radiologic management of lower gastrointestinal tract bleeding. 99mTc-sulfur colloid has a short circulating half-life of 3 min and an equally quick extraction by the reticuloendothelial system (liver, spleen, and bone marrow) (11). With incidental diverticulectomy for asymptomatic disease, the morbidity is 2%, the late postoperative complication rate is 2%, and the mortality is 1%. This is the pathology least commonly associated with Meckel diverticulum and is reported in approximately 4-5% of complicated Meckel diverticulum cases. Olga Lyass, Alexander Lossos, Ayala Hubert, Maya Gips, Tamar Peretz, Hepatic arterial bolus chemotherapy for colorectal metastases using an implantable port, S Lyass, Olga Lyass, Alberto Gabizon, Tamar Peretz, Ahmed Eid, Michael Muggia-Sullam, Arie L.

[15] The most common findings were the double-lumen sign and a visible diverticular entrance, sometimes in conjunction with ulcerative lesions. Meckel's diverticulum is a common congenital gastrointestinal malformation on the ileum resulting from incomplete atrophy of the vitelline duct in the embryo. The patient complains of passing bright red blood in the stools. 1999-2022 Cincinnati Children's Hospital Medical Center. Some institutions perform delayed dynamic imaging, which may not accurately localize the origin of bleeding unless the 4 criteria are met. CME Credit: SNMMI is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to sponsor continuing education for physicians. The imaging technique otherwise generally follows that for adults. The color of blood may vary from bright red (35 percent) to dark red or . A Meckel's Diverticulum Scintigraphy is a nuclear medicine test that detects the abnormally-located gastric mucosa. 2018 Sep. 97 (38):e12457. Gastrointestinal bleeding is one of the major causes of death in the United States, with mortality ranging from 10% to 30% (4). This method has the highest labeling efficiency, which improves the target-to-background ratio and decreases the likelihood that free pertechnetate will interfere with interpretation of the results. Mesenteric angiography for lower gastrointestinal hemorrhage: are there any predictors for a positive study? Laparoscopic management of Meckel diverticulum has largely been limited to symptoms of abdominal pain and GI bleeding. Venkata Subramanian Kanthimathinathan, MD Fellow in Bariatric/Advanced Laparoscopic Surgery, University of Missouri HealthcareDisclosure: Nothing to disclose. There is research indicating which characteristics of positive GIBS can be predictive of positivity on a subsequent angiographic examination.

Nuclear medicine has a few methods-scintigraphy with red blood cells labelled by means of (99m)Tc for detection of the source of bleeding in the small intestine, Meckel's diverticulum scintigraphy . nausea and vomiting . The iodinated contrast load is also greater (there is no nephrotoxic aspect to GIBS), although with greater localization less contrast agent might be used on a more selective angiographic evaluation or intervention. A Meckel's scan looks for the presence of Meckel's Diverticulum in the large intestine. The Meckel's Diverticulum Nuclear Medicine Study depicts the uptake of pertechnetate within the abdomen. Several potential false-positive findings can occur in GIBS. In CTA, 3 discrete CT scans of the abdomen and pelvis are generally acquired: unenhanced phase (some institutions do not obtain this phase), contrast-enhanced arterial-phase, and delayed-phase. The symptom most commonly seen in young children is painless rectal bleeding. The following anomalies are caused by the persistence of the omphalomesenteric duct: Although most commonly discovered as an incidental finding on laparotomy or laparoscopy, Meckel diverticulum can be associated with life-threatening disease states. Performance & security by Cloudflare. found that immediate visualization of bleeding on GIBS, defined as 2 min or less, was associated with a positive angiogram (43). Focus (arrows) increases in intensity over time, similar to level of gastric uptake. Meckel's diverticulum (MD) is the most frequent congenital malformation of the small intestines due to incomplete degeneration of an omphalomesenteric duct or a vitelline duct, which takes place around 5-7 weeks of the fetal period [1,2].Complications of the MD have been reported to include hemorrhage, perforation, inflammation, intestinal obstruction, stone formation, and hemia []. Meckel diverticulum, which fits well into the stapling device, is easy to remove, and removal has a low complication rate, especially when the diverticulum was found incidentally. Pluripotential cells line the omphalomesenteric duct; thus, gastric, colonic, duodenal, and pancreatic mucosa may be present. [QxMD MEDLINE Link]. None of these papers evaluated surgical planning with GIBS SPECT/CT, which enhances localization, sensitivity, and specificity. Red cell transfusion for the management of upper gastrointestinal haemorrhage. Symptoms occur only if the diverticulum bleeds, becomes infected or causes an obstruction, and they are twice as common in males than in females. Trends on gastrointestinal bleeding and mortality: where are we standing? Referencing the SNMMI procedure guideline for SPECT/CT imaging is recommended (36). Meckel's diverticulum: Rarely demonstrates an outpouching on the . To provide a patient with the best of care, timely evaluation by angiography is important after obtaining GIBS results positive for a gastrointestinal bleed. Your IP: Health Meckel's diverticulum is an abnormality in the small intestine that is present at birth. [QxMD MEDLINE Link]. Stasis in the diverticulum, especially in one with a narrow neck, causes inflammation and secondary infection leading to diverticulitis. Laparoscopic techniques are increasingly being used for Meckel diverticulectomy and intestinal resection. Yvan J Silva, MD, FACS, FRCSC Professor of Surgery, Program Director of Surgery, North Oakland Medical Centers, Wayne State University School of Medicine J Nucl Med Technol. It was in 1977 that Alavi et al., at the University of Pennsylvania, originally described evaluating gastrointestinal bleeding with scintigraphic methods using 99mTc-sulfur colloid (1). 61 (2):225-231. We recall the rule of 2s for Meckel diverticulum: 2 feet from the end of the small intestine, 2 inches in length, 2% of the population, 2 times more common in males, and presenting in the first 2 decades of life and often within the first 2 years. A discharging sinus should be approached surgically with a view toward correction. Nafisa K Kuwajerwala, MD Staff Surgeon, Breast Care Center, William Beaumont Hospital In September 2014, the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the European Association for Nuclear Medicine (EANM) issued a practice guideline for the use of scintigraphy for Meckel diverticulum. This strategy could help reduce morbidity and mortality, especially in elderly patients. Hematochezia is most often due to a lower bleed, but a brisk upper bleed could have a similar appearance. A Meckel's scan is an imaging test to look for or diagnose Meckel's diverticulum (an irregular pouch in your small intestine). Meckel diverticulum develops if the omphalomesenteric (vitellointestinal or vitelline) duct, which connects the primitive midgut with the yolk sac, fails to obliterate, which normally occurs at 7-8 weeks of gestation. [QxMD MEDLINE Link]. Meckel's diverticulum can upset your digestive system and cause nausea or vomiting. For symptoms of obstruction, diagnostic laparoscopy is not recommended, because of difficulties in establishing pneumoperitoneum. Hemorrhage is the most common complication of Meckel diverticulum, accounting for about 20-30% of all complications. In the workup of patients with obscure gastrointestinal bleed, does 64-slice MDCT have a role? Most surgeons generally do not resect a diverticulum with a wide mouth. Other reported complications in Meckel diverticulum include the following: A diagnosis of symptomatic or complicated Meckel diverticulum is difficult to confirm on the basis of traditional history, physical examination, and laboratory testing. 2020 Aug. 36 (8):869-874. Lipoma within inverted Meckel's diverticulum as a cause of recurrent partial intestinal obstruction and hemorrhage: a case report and review of literature. Previously reported sources of error include renal activity from a morphologically normal kidney, a transplanted or horseshoe kidney, urine in the bladder or urine contamination, a urinary diversion, a dilated abdominal aorta, bowel ischemia, hepatic hemangioma, vascular collaterals such as caput medusa or dilated mesenteric veins, angiodysplasia, the left ovarian artery and gallbladder in patients with renal failure, the penis, the uterus, and a uterine leiomyoma (7,20). In the few negative cases with high clinical suspicion, a repeat exam may have an additional value in detecting the Meckel's diverticulum. Focus of increasing intensity is identified in lower abdomen at midline (arrows) and shows anterograde and retrograde movement conforming to bowel lumen. The patient receives an intravenous injection of stannous pyrophosphate, which is allowed to circulate for a few minutes, followed by intravenous injection of 99mTc-pertechnetate. If this happens, your child's doctor may recommend surgery to remove it. In particular, investigators have found that SPECT or SPECT/CT can increase the sensitivity and specificity of bleeding-site localization (30). Learn about the potential risks and benefits of taking antidepressants while pregnant. 12 (10):e11065. 4100 Guardian St, Simi Valley, CA. A case of ectopic gastric adenocarcinoma has been reported. The omphalomesenteric duct is the primitive connection between the fetal yolk sac and developing midgut. Small-bowel capsule endoscopy in patients with Meckel's diverticulum: clinical features, diagnostic workup, and findings. [QxMD MEDLINE Link]. Cullen et al reported that prophylactic diverticulectomy is warranted to eliminate the possibility of future deaths. On imaging, a Meckel diverticulum is identified as a focus of activity in the lower abdomen or upper pelvis that generally appears at the time of stomach visualization and increases as stomach activity increases (Fig. Outcomes of laparoscopic resection of Meckel's diverticulum are equivalent to open laparotomy. With significant and ongoing blood loss, additional tests such as bleeding scan, colonoscopy, and angiography may be performed. The first page of the PDF . However, this risk decreases with age. [Full Text]. Surgical dissection and excision depend on the evident pathology. 2019 Mar/Apr. Vitelline cysts at umbilicus and in fibrous remnant of yolk stalk. Stapling enables faster resection of a Meckel diverticulum without the need to open the bowel's lumen, thus avoiding potential septic and postoperative complications. Dr. Nathanael Sabbah is a Nuclear Medicine Specialist in Simi Valley, CA. If the patient has had recent bowel or other abdominal surgery, prominent activity can be seen related to normal postoperative hyperemia. Please verify your coverage with the provider's office directly when scheduling an appointment. Ruscher KA, Fisher JN, Hughes CD, Neff S, Lerer TJ, Hight DW, et al. Good intravenous access is key; the patient should have 1 or 2 large-bore intravenous lines and fluid resuscitation products available on demand on entry to the nuclear medicine area. Time trends in organ position and volume in patients receiving prostate three-dimensional conformal radiotherapy. What causes a Meckel's diverticulum? Lipoma and angioma have also been found. Lyass, O., Brufman, G., Edelmann, D. Z., Prus, D., Lebensart, P. D., Peretz, T. Cardiac safety of pegylated liposomal doxorubicin (Doxil/Caelyx) demonstrated by endomyocardial biopsy in patients with advanced malignancies. Please confirm that you would like to log out of Medscape. It can do this by infolding on itself into the passageway of the intestine (intussusception). Journal of Nuclear Medicine July 1999, 40 (7) 1226-1232; Article; Info & Metrics; PDF; This is a PDF-only article. In an adult, Meckel diverticulum should be entertained in the diagnosis for lower GI bleeding, which would also include angiodysplasias, malignancy, arteriovenous malformations, and other causes. Meckel's diverticulum arises from the omphalomesenteric duct. Please try searching using the search field above.

A symptomatic Meckel's diverticulum should be resected (removed) with an operation. Am J Surg. The dynamic images can be reframed or summed on an as-needed basis to increase the information density per frame. Meckel's scans are safe, minimally invasive tests. This agents mechanism of localization is via both the parietal cells and the mucin-secreting cells of the gastric mucosa (11).
