Meckel's diverticulum is the most common congenital abnormality of the intestinal tract, occurring in 2% of autoptic studies. The case of an 85-year-old man referred to the Emergency Surgery Unit for intestinal obstruction and lower gastrointestinal tract bleeding is reported. Surgical exploration revealed a complicated Meckel's diverticulum full of coproliths, immersed in pus and blood. Examination of the resected diverticulum showed necrotic diverticulitis in the absence of ectopic gastric or pancreatic tissues.

A case of human infection with Heterophyes nocens (Heterophyidae) was incidentally found in a biopsy specimen of the Meckel's diverticulum at the upper part of the small intestine. The patient was a 58-year-old man living in a rural area of Talsonggun, Kyongsangbuk-do. He had gastrointestinal symptoms such as epigastric pain, indigestion, and abdominal discomfort for 3 months, and severe diarrhea, abdominal pain, and vomiting for about 1 month before hospitalization. Endoscopy of the upper part of the small intestine revealed a Meckel's diverticulum, and it was excised and histopathologically examined. Three adult flukes were incidentally found sectioned in the mucosa, and they were identified as H. nocens. The patient had a history of eating raw mullets at a fish market in Pusan 6 months ago, and the mullets were presumed to be the source of infection. This case brings a considerable interest in that specific diagnosis of heterophyid infections could be done by sectional morphology of the worms.

Fluorescein-labeled microspheres were orally administered to chickens and their distribution in intestinal lymphoid tissues was investigated. Polystyrene latex microspheres were observed in Peyer's patches, and also in the Meckel's diverticulum and the jejunum. Their density, however, seemed to be lower than that in Peyer's patches. Microspheres were rarely observed in the other intestinal tissues examined, including the bursa of Fabricius. Of note is that, although microspheres were present in the lumen, few, if any, were observed in the lamina propria of the caecal tonsil and caecum. Polystyrene latex microspheres of diameter 2.0 microm or 4.5 microm were also observed in Peyer's patches, but their density seemed to be lower as compared with the 0.75 microm microspheres. Poly(D,L-lactic/glycolic acid) (PLGA) microspheres were prepared using PLGAs of various molecular weights (MW) and their uptake into Peyer's patches was compared. Microspheres prepared with PLGA of average MW of 20000 were not taken up into Peyer's patches, but those prepared with PLGA of average MW of 61000 or 99 800 were taken up into Peyer's patches.

The authors performed a retrospective analysis of 108 operations performed because of Meckel's diverticulum from Jan. 1, 1980 until Dec. 31, 1997. 87 incidental operations were performed (80.55%) and 21 operations were performed (19.54%) because of complications of Meckel's diverticulum. Of the 87 incidental cases, 44 were males and 43 were females. The diverticulum was resected in 70 cases, was inverted in 16 patients and was left untouched in 1 patient. There were postoperative complications in 10 cases (11.5%), however, only one complication was related to the diverticulum operation. There was one death due to pneumonia in the incidental group (1.14%). Of the 21 cases having complications there were 5 females and 16 males. The following complications were observed: 4 cases of ileus, 7 cases of perforation (a foreign body was found in two cases) and 10 cases of inflammation. The Meckel's diverticulum was resected in 19 cases and the small intestine was resected in 2 cases. Postoperative complications occurred in 3 cases (14.3%), however these were not related to the diverticulum operations. There were 2 deaths due to pneumonia and pulmonary embolism (9.5%). Histological examination revealed 7 cases of heterotopic gastric mucosa in both the incidental group and the group with complications. There was one case of heterotopic pancreatic tissue in the group with complications. The incidence of heterotopy in the incidental group was 8%, whereas in the group with complications the incidence was 33.3%. Histological examination also revealed reflux gastritis-like diverticulitis in 5 of the patients with heterotopic gastric mucosa. Meckel's diverticulum was diagnosed in 2 patients preoperatively by upper gastrointestinal series.

A symptomatic Meckel's diverticulum (MD) may manifest as an intestinal obstruction secondary to a volvulus. We describe a case of a meconium-impacted MD associated with inflammatory adhesions to adjacent viscera that presented as an intestinal obstruction in a 4-h-old infant secondary to an ileal volvulus with resultant infarction of the diverticulum and ileal segment.

Inverted Meckel's diverticulum is an infrequent cause of gastrointestinal blood loss, especially in adults. A high index of suspicion is needed for this rare entity when entertaining the possible differentials of gastrointestinal bleeding.

Chronic intussusception as a cause of persistent abdominal pain in children is often an overlooked diagnosis. Here we present an eight-year-old boy, who at the age of three years had an acute intussusception reduced hydrostatically with barium and who subsequently had been extensively investigated both in Wales and in Switzerland, for persistent colicky abdominal pain. He was found to have chronic intussusception, with a Meckel's diverticulum being the cause of his symptoms.

Although Meckel's diverticulum is the commonest congenital gastrointestinal anomaly, there is still debate concerning the proper management of asymptomatic diverticula. Records of all patients whose Meckel's diverticulum was resected at our hospitals between 1990 and 2002 were reviewed. Clinical characteristics, mode of presentations, and management for all patients were analyzed. Meckel's diverticula were resected in 68 patients. Patients were divided into two groups: the incidental group included 40 patients (24 males) in whom the diagnosis of diverticula was incidental. The symptomatic group included 28 patients (20 males) who presented with diverticulum-related complications. Preoperative diagnosis was possible in only four cases. In four patients from the symptomatic group, Meckel's diverticula were found and left untouched during a previous laparotomy. There was no significant difference between the two groups with respect to gender (p = 0.48). Patients in the symptomatic group were significantly younger than patients in the incidental group (p = 0.002). The diverticula in the symptomatic group tended to be longer (p = 0.001) with a narrower base (p = 0.001) than the diverticula in the incidental group. A diameter of < or = 2 cm was significantly associated with more complications (p = 0.01). Heterotopic tissue was present more significantly in the symptomatic group than the incidental group (p = 0.01). There was no significant difference in the morbidity rate between the two groups (p = 0.71), and there was no mortality in either group. Preoperative diagnosis of Meckel's diverticulum is difficult and should be kept in mind in cases of acute abdomen. Resection of incidentally found diverticula is not associated with increased operative morbidity or mortality.

Video-capsule endoscopy was used in 4 children with unexplained symptoms of the small intestine. Each patient swallowed a capsule of 11 by 27 mm, which contained a camera that takes 2 images per second (in children aged less than 8 years, the capsule was placed in the duodenum under sedation). In a 3-year-old girl with rectal bleeding following partial resection of the colon and small intestine, ulcers were seen proximal to the ileorectal anastomosis. In a 14-year-old boy with Crohn's disease and an abnormal growth curve, multiple stenoses of the small intestine were seen. In an 8-year-old boy with rectal bleeding, a solitary polypoid mass was seen that, upon operation, appeared to be the result of a partially invaginated Meckel's diverticulum. In a 17-year-old boy with weight loss, rectal bleeding and colitis, abnormalities were seen that were consistent with Crohn's disease. Patients were treated based on the endoscopic results and subsequently recovered. Video-capsule endoscopy is non-invasive and painless and provides better images of the small intestine than a standard endoscopic and radiological examination.
