Abstract

Background. Incisional hernia (IH) is the most frequent complication after abdominal operation, with an incidence of 11-20% and up to 35% in risk groups. Known risk groups for IH are abdominal aortic aneurysm and obesity. Our hypothesis is that parastomal hernia (PH) might also represent a risk factor for developing IH. Identifying risk factors can help determine the need for preventive measures such as primary mesh augmentation. Methods. In a multicenter cross-sectional study, all patients who were operated between 2002 and 2010 by means of a Hartmann procedure or abdominoperineal resection were invited for a follow-up visit to our outpatient clinic. Primary outcome measures were the prevalence of IH and PH. All possible risk factors for IH were scored. A physical examination was performed and, when available, computed tomography was scored for IH and PH. Results. A total of 150 patients were seen in the outpatient clinic. The median follow-up was 49 months (range, 30-75). IH had a prevalence of 37.1%, and PH had a prevalence of 52.3% during physical examination. On CT the prevalence was even greater, ie, 48.3% and 52.9%. IH and PH were both present in the same patient in 30% of all examined and in 35.6% after CT examination. PH was found to be a risk factor for IH on univariate and multivariate logistic regression analyses of variance, with an odds ratio of 7.2 (95% confidence interval 3.3-15.7). In addition, an emergency operation was found to be a risk factor for IH with an odds ratio of 5.8 in the multivariate analyses. Conclusion. Patients with a PH have a 7 times greater chance of developing an IH compared to patients without PH.
