A total of 600 cases, comprising 4 of our cases and 596 others in Japan, was analyzed, and the diagnosis of Meckel's diverticulum was made in only 34 of them. The rate of diagnosis was 5.7 per cent, which is very low. The most common complication of this disease was intestinal obstruction, the second most common was intussusception, the third was inflammation, and the fourth was rectal bleeding. Ectopic tissue, present in ninety-three patients, consisted of ectopic gastric mucosa in fifty-eight. 99mTc-P scanning was performed on fifteen patients. In twelve of them ectopic gastric mucosa was observed. However, it was not found in three, all of whom had false-positive scans.

Examination for Meckel's diverticulum is generally performed in each case of laparotomy where the incision allows observation of the small bowel without danger of spreading the infection. In 65 cases, pathologic alterations were found in 14 (= 21,5%). Postoperative bowel obstruction due to resection of Meckel's diverticulum has been found twice (3%), one patient died. It is suggested that Meckel's diverticulum be removed whenever possible.

Acute intestinal obstruction in a women, aged 56, was caused by a highly malignant adenocarcinoma arising in a Meckel's diverticulum. Despite radical surgery, the tumour recurred after four months, and the patient died nine months after her first operation. This confirms the general bad prognosis associated with carcimomas of Meckel's diverticulum.

A new case of an enterolith, formed within a Meckel's diverticulum and subsequently expellefferential diagnosis from a gallstone ileus is virtually impossible. This nevertheless remains a rare cause of intestinal obstruction.

Calcified enteroliths are an uncommon sign of stasis of intestinal contents in the distal small intestine, usually caused by Meckel's diverticulum, Crohn's disease or other stenosing lesion. Although enteroliths are occasionally associated with intestinal obstruction the clinical picture in this case was dominated by perforation of the ileum by a small enterolith. The relevant literature is discussed.

In twenty years, 66 infants and children with remnants of vitelline duct requiring surgery have been admitted. The patients were classified into three groups: patient vitelline duct (20 cases); Meckel's diverticulum as the primary surgical diseases (19 patients); and Meckel's diverticulum found incidentally at surgery (27 patients). The male preponderance in the groups of patent vitelline duct and symptomatic Meckel's diverticulum was 9:1. In contrast with other data, Meckel's diverticulum requiring surgery occurred with nearly equal frequency up to fourteen years. The gravest complication in the cases of patent vitelline duct were a T-shaped protrusion of ileum and a small bowel volvulus around the fibrous cord or the patent duct; and in the cases of Meckel's diverticulum causing symptoms, intestinal obstruction, bleeding peptic ulceration or inflammation. Three deaths occurred in newborn age in connection with patent vitelline duct, and one patient died who belonged to the group of asymptomatic Meckel's diverticulum.

The mesodiverticular band is an embryologic remnant of the vitelline circulation which carries the arterial supply to the Meckel's diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herinate and become obstruced. Clinical and radiological findings of acute, low, small-bowel obstruction are produced by this band.

To determine the natural history of Meckel's diverticulum, 202 case records of proved disease of Meckel's diverticulum were retrieved, covering a fifteen year period, from all the hospitals of King County, Washington (population, 1,143,800). Using the figure of 2 per cent incidence of Meckel's diverticulum, we calculated that a Meckel's diverticulum has a 4.2 per cent likelihood of causing disease during a lifetime, decreasing to zero with old age. Using previously published mortality and morbidity figures, we calculated that to save one patient's life from the complications of Meckel's diverticulum, it would be necessary to remove approximately 800 asymptomatic Meckel's diverticula. This would be likely to incur a significant amount of postoperative morbidity from postoperative intestinal obstruction and infection. We suggest that the prophylactic removal of Meckel's diverticulum is rarely, if ever, justified.

Meckel's diverticulum is the most common congenital abnormality of the small intestine, occurring in about 2 per cent of the population. Complications of a Meckel's diverticulum, including hemorrhage, inflammation, bowel obstruction, and neoplasms, occur in 15 to 33 per cent of cases and invariably demand operative treatment. When signs or symptoms arise from a Meckel's diverticulum, morbidity and mortality are high. Incidental Meckel's diverticulectomy should be performed at any age when the morbidity and mortality of the primary procedure will not be increased substantially.

Intussusception is one of the leading causes of bowel obstruction in early infancy and childhood. From 1984-1989, 67 patients under 2 years of age with intussusception were diagnosed and treated in our institution. There were 48 boys and 19 girls ranging in age from 2 months to 2 years with a mean of 7.4 months. Presenting symptoms and signs included abdominal pain (96%), vomiting (93%), rectal bleeding (60%) and a palpable mass (67%). Symptoms and signs were present for less than 24 hours in about 80% of cases. Most of the intussusceptions were of the ileocolic type (75%). The overall success rate of hydrostatic barium enema reduction was 49%. The highest rate of reduction by enema was among patients between 9 and 16 months of age (83%). The success rate of barium enema reduction was negligible after 24 hours of cardinal symptoms. Five children underwent surgical exploration without contrast studies because of delayed presentation and signs of an acute abdomen. A pathological lead point was found in only four cases, the commonest being Meckel's diverticulum. The average length of hospitalization was 2.57 days after barium enema reduction and 7.55 days after surgical reduction. There were no deaths. There was no case of perforation during enema reduction. Three children had recurrence within 3 months of initial presentation. The best outcome is associated with early diagnosis and barium enema reduction, or selected surgical intervention when indicated.
