Meckel's diverticulum in Amsterdam: experience in 136 patients.

The object of this study was to establish the relation of symptomatic diverticula to the age and gender of the patients and to the presence of ectopic tissue. A total of 136 patients with surgically treated diverticula were collected from the medical charts of five Amsterdam hospitals; 51 had undergone resection because of diverticulum-related symptoms and 85 during laparotomy for other causes. Obstruction was the predominant symptom (39%) in the 51 symptomatic patients. Hemorrhage, perforation, diverticulitis, and intussusception were the other symptoms (12-14% each). Obstruction occurred mainly in patients under age 10 years and perforation in patients 10 to 30 years old. All symptoms, hemorrhage excepted, occurred two to four times more in men. Hemorrhage and perforation were associated with the presence of ectopic gastric tissue. We concluded that symptoms caused by Meckel's diverticula are mainly due to the presence of bands or ectopic gastric tissue. The symptoms manifest at an early age (77% in those under age 30) and predominantly in males. Diverticula found incidentally in patients younger than 30 years should be resected. In the older patients, resection is indicated if ectopic gastric tissue is suspected. Diverticular bands can simply be cut.

Role of Helicobacter pylori in the pathogenesis of complications of Meckel's diverticula.

OBJECTIVE: To assess the possible role of colonisation of ectopic gastric mucosa in Meckel's diverticula by Helicobacter pylori in causing inflammation, ulceration, perforation and bleeding. DESIGN: Retrospective study. SETTING: Three hospitals in Amsterdam, The Netherlands. MATERIAL: Specimens of 65 diverticula, 49 of which had been resected incidentally, and 16 of which had been thought to be the presenting feature. MAIN OUTCOME MEASURE: The presence of H. pylori in gastric mucosa. RESULTS: 19 Diverticula contained ectopic tissue, 18 gastric and one pancreatic tissue. Gastric tissue was found in 10 of the diverticula removed incidentally, and 8 of those that were thought to be symptomatic. In 5 of the 8 there were signs of complications that might have been related directly to the presence of gastric tissue (perforation--n = 3; bleeding--n = 1; and peptic stenosis--n = 1), and none contained H. pylori. H. pylori was found in only one of the 18 diverticula, in which there were also signs of gastritis. CONCLUSION: H. pylori has no role in the pathogenesis of the complications of Meckel's diverticula.
