Diverticular disease of the small bowel.

BACKGROUND/AIMS: The clinical picture of small bowel diverticula has not been well-clarified because of its infrequent incidence and limited case number in most published reports. We evaluated a large series of small bowel diverticula and further compared the clinical picture of the diverticula at different parts of small bowel.

METHODOLOGY

The medical records of 88 patients with diverticular disease of the small bowel were reviewed from 1979-1997. This study included all diverticula from duodenum to ileum.

RESULTS

The most common small bowel diverticulum was duodenal diverticulum (45%), followed by Meckel's diverticulum (23%). The most common clinical presentation was abdominal pain (48.9%), followed by gastrointestinal bleeding (29.5%). However, among the Meckel's diverticula, gastrointestinal bleeding (60%) was the most common presentation. The accurate diagnostic rate for diverticula, overall, was 25.0%. Thirty-nine (44.3%) of the diverticula were found incidentally. Twenty-three cases (26.1%) were diagnosed by gastrointestinal barium study. Thirty-eight (42.1%) diverticula were left alone without any sequela, and the remaining 55 (56.8%) diverticula needed either bowel resection (30.7%) or diverticulectomy (26.1%). All of the Meckel's diverticula were treated by surgery. Postoperative complication occurred in 9 (10.3%) patients. Hospital mortality rate was 3.4%.

CONCLUSIONS

Duodenal diverticulum was the most common small bowel diverticulum. Abdominal pain and gastrointestinal bleeding were the most common clinical presentations. The small bowel diverticula, except for Meckel's diverticulum, did not need to be treated if there were no significant symptoms.
