Meckel's diverticulum is the congenital anomaly of the gastrointestinal tract affecting about 2% of the population. It is a true diverticulum containing all layers of the ileum wall. Heterotopic tissue is frequently present (25%): gastric mucosa, duodenal mucosa, jejunal mucosa and pancreatic tissue. Meckel's diverticulum is localized about 50 cm from the ileo-colic valve on the external border of the ileum. Most of Meckel's diverticula are clinically silent; clinical symptoms (19%) are in cases of complications such as: strangulation of the bowel in a ring formed by the diverticulum, intussusception of the diverticulum into the ileum, volvulus, incarceration of the diverticulum in hernia, tumour originating in the diverticulum. The diagnosis of Meckel's diverticulum is very difficult. The most useful in the diagnosis are plain abdominal radiographs, barium studies, CT, sonography and scintigraphy Abdominal sonography shows a tubular fluid structure localized far from the coecum. The wall of the diverticulum is swollen and in the lumen are chyme or fat.

Herein, we report on an adult with intussusception of an invaginated Meckel's diverticulum presenting mainly with acute intermittent lower gastrointestinal bleeding, whereas the common symptom of abdominal pain, indicating intussusception, was absent. Colonoscopy revealed a reducible polypoid lesion in the ileocecal area. Computed tomography led to suspicion of an intussusception. Surgical resection revealed a Meckel's diverticulum containing an aberrant pancreas. The unique clinical symptoms and the methods of diagnosis are discussed.

A 63-year-old male was referred because of colicky pain due to an intussusception of a Meckel's diverticulum and of the ileum into the cecum.

Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract with a potential risk to develop complications such as obstruction, diverticulitis or intussusception. Lower gastrointestinal bleeding due to ulceration of heterotopic gastric tissue of the diverticulum is a known phenomenon in children and young adults. We present two cases of a 15-year-old girl and a 20-year-old man that revealed a massive lower gastrointestinal hemorrhage of unknown origin. In this emergency situation laparotomy was performed in combination with lower endoscopy as rendezvous manouver. In both cases a Meckel's diverticulum with peptic ulceration was the source of hemorrhage, in one case the bleeding was active and visible. After resection of a short small bowel segment and end-to-end anastomosis the postoperative course was uneventful. We prefer in the case of lower gastrointestinal hemorrhage with hemodynamic instability laparotomy with intraoperative endoscopy instead of laparoscopy.

Intussusception due to an inverted Meckel's diverticulum is considered a rare occurrence. We present a case of a 37-year-old male with anemia and melena due to an inverted Meckel's diverticulum at the base of an ileoileal intussusception. To our knowledge, this is the first case in which small bowel enema, computed tomography, and magnetic resonance imaging showed the pathology.

Nowadays, laparoscopy appears to be an attractive alternative to conventional surgery in the management of small bowel obstruction. Adult intussusception is an unusual cause of intestinal obstruction, and a wide range of pathologic conditions can result with intussusception. In this report, we present a very rare case of intussusception secondary to inverted Meckel's diverticulum in an adult who underwent laparoscopic surgery. The diagnostic modalities and surgical management of intussusception are discussed.

Indications and contraindications for diagnostic laparoscopy in cases of intestinal obstructions are discussed in connection with a 16-year-old patient's case report with small bowel obstruction including intussusception, volvulus and appendicitis caused by an inflammatory Meckel's diverticulum. The use of diagnostic laparoscopy in cases of intestinal obstructions is controversial. In the described case we performed completely laparoscopically the derevolving and desusception of the volvulus and intussusception, the appendectomy and resection of the diverticulum. The procedure itself and the postoperative course were uneventful.

We describe a case of Meckel's diverticulum containing ectopic gastric epithelium being the leading point in an ileoileal intussusception. This is usually an acute or subacute condition, but in this case the course was protracted and the case was misdiagnosed and treated as Crohn disease.

To determine the morbidity and mortality of Meckel's diverticulum (MD) as a cause of acute abdominal disorders and to evaluate the relationship between patient age, MD complications, and postoperative complications. We reviewed 74 patients who underwent surgery between 1990 and 2000 for an acute abdominal syndrome with a MD diagnosed intraoperatively. Forty children were treated before 1995 and reviewed retrospectively, while the remaining 34 were reviewed prospectively. The average age was 4.8 years; the male/female ratio was 2.5/1; 34 (46%) were less than 2 years old, 32 were between 2 and 8 years, and 8 were older than 8 years. None of the symptoms was suggestive of the diagnosis of MD. Thirty-nine MDs were asymptomatic (21 intussusception, 18 volvulus), but all were the secondary cause of the acute abdomen. The remaining 35 children had a symptomatic MD (diverticulitis in 14, diverticular bleeding in 11, diverticular perforation in 10). The risk of complications due to a MD occurring in children under 2 years and between 2 and 8 years of age was significantly higher compared to children older than 8 years (P = 0.02). Postoperative complications occurred more commonly in children between 2 and 8 years of age compared to other patients. There is thus an increased risk of morbidity in a symptomatic MD in patients less than 2 and between 2 and 8 years of age, and there is no predictive factor for the development of diverticular complications. Resection of the MD is recommended in all children younger than 8 years, including asymptomatic ones, in the absence of absolute contraindications.

Intussusception occurs commonly in children, but rarely is observed in adults. Whereas the hydrostatic pressure of a contrast enema often proves diagnostic as well as therapeutic in infants and children, resection usually is required for an underlying bowel pathology in older children and adults. Conventionally, the resection is accomplished at laparotomy. We report the case of a 20-year-old woman who presented with diarrhea and vomiting of 1 week duration. She was found unexpectedly to have intussusception on abdominal ultrasonography. The intussusception was laparoscopically reduced, and a segment of the middle small bowel that harbored an inverted Meckel's diverticulum was resected laparoscopically, after which an intracorporeal anastomosis was fashioned. The ileus resolved on postoperative day 4, and the patient was discharged from hospital on postoperative day 5. The role of the laparoscopic approach in the management of intussusception is discussed.
