Summary

Paradiverticulitis, minor bleeding from colonic diverticula, is a source of fecal occult blood. This study identifies three types of paradiverticulitis, clarifying its role in positive occult blood tests.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery

Background:

  • Colonic diverticula are known causes of massive gastrointestinal bleeding.
  • The contribution of colonic diverticula to fecal occult blood loss remains poorly understood.

Purpose of the Study:

  • To investigate the potential for minor bleeding from colonic diverticula and diverticulosis.
  • To identify and characterize sources of fecal occult blood loss in patients with diverticula.

Main Methods:

  • Retrospective analysis of 737 cases of colonic diverticula diagnosed between April 1989 and May 1994.
  • Colonoscopic evaluation to identify sources of positive fecal occult blood tests.
  • Prospective study of 595 diverticula cases over two years.

Main Results:

Related Experiment Videos

  • Thirty-seven cases (5%) of diverticula were identified as sources of positive occult blood tests.
  • Three types of bleeding were identified: intradiverticular, peridiverticular, and interdiverticular.
  • Prospective study identified 67 cases (11.3%) of paradiverticulitis.

Conclusions:

  • Paradiverticulitis, encompassing bleeding from intradiverticulitis, peridiverticulitis, and interdiverticulitis, is a significant cause of fecal occult blood loss.
  • This research clarifies the role of colonic diverticula in minor gastrointestinal bleeding.
