Incisional hernia after loop ileostomy closure

Introduction: Incisional hernia at the stoma site after loop ileostomy reversal has a high incidence reaching 48 % in some studies. Risk factors have not been largely studied. Material and methods: This retrospective study includes all consecutive patients who underwent stoma reversal between 2010 and 2018 at the Department of General Surgery of the Basurto Hospital in Bilbao (Spain). Results: A total of 134 patients (42.54 % female, 57.46 % male) had a stoma reversal operation. A postoperative incisional hernia at the stoma reversal site developed in 11.19 % during a median follow-up of 47-52 months. Body mass index over 30, was associated with incisional formation at the stoma reversal. Conclusions: Incisional hernia rate at the former stoma site in our study was moderated, obesity was the main risk factor.
