Perforated jejunal diverticulitis

Case contributed by Dr Domenico Nicoletti


Acute abdomen

Patient Data

Age: 65 years
Gender: Male

There are numerous duodenal and jejunal diverticula.

A jejunal diverticulum shows signs of micro perforation with increased density of the adjacent adipose tissue.There is also a small peritoneal effusion.

In the upper quadrants some loops are dilated with parietal hypertonus, adherent to each other.

Case Discussion

Jejunal diverticula are usually multiple and localized to the proximal jejunum. Jejunoileal diverticula may be composed of mucosa and submucosa only, or of all layers of the jejunal wall. The cause of jejunoileal diverticula is unclear, but intestinal dyskinesia, and high intraluminal pressure have been implicated in the pathogenesis.

The most frequent complications are:

  • complete small bowel obstruction due to a volvulus.
  • development of an abscess
  • diverticular perforation.
  • gastrointestinal bleeding
