Background

Digestive diseases have been associated with obesity, including gastroesophageal reflux disease, gallstone disease, cancers and colonic diverticular disease. However, the relationship between obesity and diverticular complications is yet to be defined. We conducted the present study to clarify the association of central obesity with the risk of complicated diverticulitis.

Methods

151 patients were selected, who were diagnosed with colonic diverticulitis by abdominal CT. For measuring obesity, body mass index (BMI) was calculated and the visceral fat area (VFA), subcutaneous fat area (SFA), total fat area (TFA) and abdominal circumference(AC) were determined from CT images. All parameters were analyzed using univariate statistics and multivariate logistic regression models.

Results

Out of the 151 patients with colonic diverticulitis, 143 (94.9%) cases involved the proximal colon. In 39 patients with complicated diverticulitis, 27 cases involved abscess formations and 12 cases showed perforated diverticulitis. Univariate analysis identified age, male sex, VFA, VFA/TFA and AC as risk factors associated with complicated diverticulitis (P < 0.05). However, after adjusting for age and sex, none of the parameters showed increased risk for complicated diverticulitis.

Conclusions

Central obesity may not be a risk factor for increasing the risk of complicated colon diverticulitis in the Korean population.
