ARTICLE HIGHLIGHTS
Research background
Diverticulosis coli is one of the leading causes of morbidity in Western countries. Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis.
Research motivation
Despite its high prevalence, the pathogenesis of colonic diverticulosis remains poorly understood.
Research objectives
We sought to assess whether previous abdominal surgery, presumably by means of adhesion-related increased colonic intraluminal pressure, is associated with colonic diverticulosis or diverticulitis.
Research methods
Patients undergoing colonoscopy completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking and alcohol use, and co-morbidities. The presence of diverticulosis was identified via colonoscopy.
Research results
Three hundred and fifty-nine patients were included in the study. The overall prevalence of colonic diverticulosis was 25% (91/359) and 48% of the patients had previous abdominal surgery. There was no difference in the rate of previous abdominal surgery between patients with or without diverticulosis (49% vs 47%, P = 0.78). In regards to specific surgeries, inguinal hernia repair was significantly associated with diverticulosis (52% vs 20%, P = 0.001), but not diverticulitis. In contrast, appendectomy was not associated with diverticulosis (6% vs 14%, P = 0.048).
Research conclusions
These findings suggest that post-operative abdominal adhesions inducing high colonic intraluminal pressures do not appear to be the mechanism for diverticula formation. Rather, inguinal hernia and diverticulosis may share similar connective tissue pathologies with no causative relationship between them.
Research perspectives
The pathogenesis of colonic diverticulosis remains unclear and future studies are needed.
