O30 THE INCIDENCE OF INCISIONAL HERNIA AT OSTOMY-REVERSAL SITE

Abstract

Abstract Aim The purpose of this study was to evaluate the rate of incisional hernias at the ostomy site after reversal of the ostomy. Material and Methods We used retrospectively compiled database of patients who had undergone ostomy formation and ist reversal. All patients had their surgery performed between Jan. 2011 and December 2019. Patients history, added by clinical examination and CT-scan were performed in order to identify the incidence of incisional hernias. Different variables, like gender, surgical site infection (SSI) and BMI were evaluated as possible risk factors for hernia occurrence. Results Among totally included 224 patients in the study, 190 of all patients had reversal after loop-ileostomy (85%) and 34 patients had reversal after loop-colostomy (15%). Among all stoma reversal patients, 12,8 % developed incisional hernia at the stoma reversal site (n = 28). The incisional hernia occurrence at the ostomy reversal site was present in 20,0% in patients with clinically relevant SSI and only in 9,4% in patients where SSI was absent (p = 0,03). There was no statistical significance in hernia occurrence between both genders and among patients with low, normal and high BMI in our cohort of patients. Conclusions Incisional hernia after ostomy reversal is a common late surgical complication. All measurements that reduce SSI at the reversal site are important for lower hernia incidence. Prophylactic mesh implantation at stoma reversal sites may be considered in these patients.
