Meckel's diverticulum is the most common congenital abnormality of the small bowel. The majority of patients with this anomaly will remain asymptomatic; however, several complications may occur, including obstruction, intussusception, perforation, diverticulitis, and gastrointestinal haemorrhage. These complications may produce a variety of different clinical features and radiological appearances. The purpose of this article is to review the potential imaging manifestations of Meckel's diverticulum and its complications and discuss the advantages and disadvantages of the imaging techniques available.

Intussusception of the bowel is defined as the telescoping of a proximal segment of the gastrointestinal tract within the lumen of the adjacent segment. This condition is frequent in children and presents with the classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass. However, bowel intussusception in adults is considered a rare condition, accounting for 5% of all cases of intussusceptions and almost 1%-5% of bowel obstruction. Eight to twenty percent of cases are idiopathic, without a lead point lesion. Secondary intussusception is caused by organic lesions, such as inflammatory bowel disease, postoperative adhesions, Meckel's diverticulum, benign and malignant lesions, metastatic neoplasms or even iatrogenically, due to the presence of intestinal tubes, jejunostomy feeding tubes or after gastric surgery. Computed tomography is the most sensitive diagnostic modality and can distinguish between intussusceptions with and without a lead point. Surgery is the definitive treatment of adult intussusceptions. Formal bowel resection with oncological principles is followed for every case where a malignancy is suspected. Reduction of the intussuscepted bowel is considered safe for benign lesions in order to limit the extent of resection or to avoid the short bowel syndrome in certain circumstances.

Intussusception with the Meckel's diverticulum is a rare but well-known cause of small bowel obstruction in the adult. After blunt abdominal trauma, intussusception is exceedingly rare and has been reported previously only in few cases. We present a case of a previously healthy 28-year-old man developing four days after blunt abdominal trauma signs of small bowel obstruction. Ileo-ileal intussusception was suggested by computed tomography. Exploration revealed ileo-ileal intussusception with Meckel's diverticulum. A diverticulectomy with small bowel resection was performed.

Meckel's diverticulum (MD) has varied clinical manifestations and is a diagnostic challenge for pediatricians. This study investigates the clinical and diagnostic characteristics of MD in children with different presentations. We retrospectively reviewed the medical records of pediatric patients diagnosed with MD from 1988 to 2008. The data including the age, sex, clinical features, laboratory data, sensitivity of diagnostic methods, and pathological finding were recorded. These patients were classified into three groups: diverticulitis, intestinal obstruction, and intestinal bleeding. A total of 47 children (35 boys and 12 girls) with a median age of 5.6 years were enrolled and categorized as follows: diverticulitis (n = 12), obstruction (n = 12), bleeding (n = 21), and two diagnosed incidentally. Patients with intestinal obstruction were significantly younger than those with bleeding (3.7, 95% CI, 1.6-5.7 vs. 6.6, 95% CI, 4.5-8.7, P = 0.04). In the obstruction group, intussusception was found in eight of 12 patients, of whom 62.5% were aged older than 3 years. Heterotopic tissues were found in 46.3% of surgical specimens and more frequently existed in patients with bleeding than those with diverticulitis (P = 0.02) and obstruction (P = 0.047). Tc-99m scans yielded a diagnostic sensitivity of about 65% in bleeding patients. Repeated Tc-99m scans and red blood cell (RBC) scans can be good supplementary tools in Tc-99m scan-negative bleeding patients. In conclusion, manifestations of childhood MD are variable and may depend on the presence of heterotopic tissues and the patients' age. Tc-99m scans supplemented with RBC scans are appropriate to diagnose childhood MD with bleeding.

Meckel's diverticulum is the most common congenital anomaly of the gastro-intestinal tract. It is generally asymptomatic. Occasionally, it may cause some complications such as bleeding, obstruction, diverticulitis and intussusception. We present a case of a 21-year-old female with intussusception due to inverted Meckel's diverticulum. Diagnosis and therapy of inverted Meckel's diverticulum is a subject of debate because of its rarity and the limited number of reports in the literature.

We report colonoscopic features of an intussuscepted Meckel's diverticulum, presenting with hematochezia. A 35-year-old woman presented to the emergency room with acute onset, transient, sharp, severe epigastric pain that began 6 h earlier. Colonoscopy revealed a reddish, soft, fist-sized polypoid lesion in the terminal ileum. The lesion was misinterpreted as a hematoma by an inexperienced endoscopist. The patient began to complain of intermittent, severe periumbilical pain following the colonoscopic examination. Subsequent computed tomography showed an enteric intussusception. An exploratory laparotomy revealed an intussuscepted Meckel's diverticulum, with transmural infarction. Colonoscopy was of little use in assessing the intussusception. However, colonoscopic examination may be performed initially, especially in an intussuscepted Meckel's diverticulum presenting with hematochezia. Endoscopists should note the endoscopic features of an intussuscepted Meckel's diverticulum.

Colocolonic intussusception is an uncommon cause of intestinal obstruction in children. The most common type is idiopathic ileocolic intussusception. However, pathologic lead points occur approximately in 5% of cases. In pediatric patients, Meckel's diverticulum is the most common lead point, followed by polyps and duplication. We present a case of recurrent colocolonic intussusception which caused colonic obstruction in a 10-year-old boy. A barium enema revealed a large polypoid mass at the transverse colon. Colonoscopy showed a colonic polyp, 3.5 centimeters in diameter, which was successfully removed by endoscopic polypectomy.

Meckel's diverticulum (MD) is the most common congenital anomaly of the small intestine. We searched and analyzed the records of 62 cases with MD admitted in University Emergency Hospital Bucharest between 2001-2009. Sex ratio was M:F 3:1, with 74% male and 26% female. 51.6% (n = 32) of this where symptomatic and 48.4% (n = 30) asymptomatic, discovered during laparotomy for other reasons. The analysis highlights an increased frequency of symptomatic diverticulum at early ages, with a medium age of about 39.2 years comparing to asymptomatic group with a medium age of about 54.2 years. The diverticulum complication generated: occlusion--43.7% (n = 15), inflammation--37.5% (n = 12), bleeding, two cases of diverticulum tumor, an intussusception case and a perforation case with unknown object. 25% of the diverticulectomies were followed by postsurgery complications, the parietal suppuration being the most frequent (50%). Three patients died independent of the diverticulum or its resection, all three having an asymptomatic diverticulum. The difficult diagnosis and the seriousness of diverticulum complications force us to take into consideration DM in all cases of severe or chronic abdominal pain. The diverticulum has to be surgically removed to all patients under 50 years, especially men.

Abdominal pain in child could be related to surgical pathologies in 10 to 20 % of cases. The more frequent etiology remains appendicitis. Regarding to clinical presentation, age and medical history, intestinal intussusception, incarcerated hernia, adhesive occlusion and Meckel's diverticulum could be evocated. But the most dreadful diagnosis is malrotation with volvulus, because of mortality and morbidities induced by bowel necrosis. Usually, medical history and clinical exam allowed diagnosis. Ultrasound remains the more helpful exam in children with surgical pathologies and in some selected cases, CT scan and others biological and/or radiological exams could be performed.

Adult intussusception due to Meckel's diverticulum (MD) is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report two cases of intussusception due to MD in adults. A diverticulectomy using a TA stapler was performed in the first patient. In the second patient extensive fibrosis of the adjacent mesentery and thickening of jejunal mucosa were observed, so a segmental resection of the small bowel or affected ileal part and a hand-sewn anastomosis was performed. The postoperative period along with the long term follow-up was uneventful for both patients. The decision between diverticulectomy vs bowel resection can be based on the intussuscepted bowel condition. Early surgical intervention may ensure a favorable outcome.
