Inverted diverticula of the gastrointestinal tract are rare. This paper briefly presents the roentgen findings of an inverted Meckel's diverticulum and is the first reported case of the roentgen appearance of an inverted colonic diverticulum.

Diverticula, or multiple sacculations, of a Meckel's diverticulum are a relatively unknown and undocumented pathologic entity. A case is reported, and another case recalled. In both cases, the sacculations were in the fundus. There was partial or complete absence of muscular layers in the saccular wall. A congenital origin of these muscular defects is more likely than is an origin from acquired hydrostatic pressure.

Many small bowel abnormalities selectively involve the mesenteric or antimesenteric borders of small intestinal loops solely or predominantly. This report documents the roentgen localization and diagnosis of a variety of intraabdominal disease states by their effects specifically on the mesenteric or antimesenteric margins of small bowel loops. The conditions with selective or predominant involvement of either the mesenteric or antimesenteric borders include diverticulosis, Meckel's diverticulum, intestinal duplication, seeded metastases, hematogenous metastases, regional enteritis, lymphoma, and intestinal ischemia and intramural bleeding.

99mTc-pertechnetate scintigraphy in a 67-year-old woman with chronic gastrointestinal bleeding showed an area of increased activity in the right lower quadrant which appeared at the same time the stomach was visualized. At first this was thought to be a Meckel's diverticulum; however, superior mesenteric angiography subsequently revealed a small arteriovenous malformation which proved to be the bleeding site on laparotomy. This false-positive finding emphasizes the importance of comparative evaluation of early and late images in scintigraphy for suspected 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.

A case report of hemoperitoneum following perforation of Meckel's diverticulum as a rare complication is presented. Symptoms and diagnostic problems are discussed.

An infrequent case of puncture of Meckel's diverticulum whose aetiopathogenesis was attributed to a segmentary intestinal dyskinetic phenomenon is reported. The pneumoperitoneum consequent on the puncture was not associated with peritonitis and histology showed that the diverticulum did not show either inflammatory phenomena or areas of ectopic mucosa, namely none of the causes which are usually at the origin of Meckel's diverticulum puncture.

99mTc-pertechnetate scintigraphy of the digestive tract was performed on 4 children with intestinal bleeding. Two of them showed a focal uptake in the right lower abdominal quadrant and a diagnosis of bleeding Meckel's diverticulum was confirmed by surgery. This procedure being easy to perform, non-invasive and remunerative, should be systematically applied in paediatric intestinal bleeding.

Thirty pneumoperitoneograms were performed postmortem and 5 were performed for diagnosis: the technique itself, the radiological anatomy of the umbilical region, and the usefulness of the procedure in diagnosis are discussed. Pneumoperitoneum may be indicated in the investigation of a bleeding Meckel's diverticulum, in the exclusion or confirmation of remnants of the omphalomesenteric duct, in chronically moist lesions of the umbilicus resistant to symptomatic treatment, in suspected cases of non-communicating urachal cysts which cannot be diagnosed by cystogram, and in the differential diagnosis of abdominal tumours related to the umbilical region.

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.
