Parastomal Hernia Repair With 3-D Mesh Implants After Radical Cystectomy and Ileal Conduit Urinary Diversion - A Single-center Experience Using a Purpose Made Alloplastic Mesh Implant

Abstract

ObjectiveTo report and evaluate our open surgical technique for the treatment of parastomal hernias (PSH) after ileal conduit urinary diversion and results using a specifically designed, three-dimensional intraperitoneal onlay mesh aiming to minimize PSH recurrence and perioperative complications. MethodsWe retrospectively evaluated all patients who developed a PSH after ileal conduit urinary diversion and were treated with the 3-dimensional alloplastic IPST mesh at the Marien Hospital Herne, Ruhr-University Bochum, Germany between 01/2009 and 12/2015. As a surgical approach, we used a small, open incision in order to reduce the hernia sac and place the mesh. Subsequently, we performed a voluntary follow-up of the surviving patients to evaluate long-term recurrence and complication rates. In addition, we conducted a reassessment of the cross-sectional imaging available. ResultsBetween January 2009 and December 2015, 40 patients underwent hernia repair due to a clinically significant hernia. Out of those patients, 1 suffered from a postoperative wound infection. In total 27 patients participated in a voluntary follow-up with a median follow-up period of 29 months (IQR 16, 63 months). Follow-up examination revealed 2 cases of recurrent PSH (7, .4%), 2 patients who developed stoma stenosis (7.4%) and 5 patients who suffered from minor complications (18.5%). ConclusionOur localized open surgical approach using a 3-dimensional mesh implant presents an effective method of treating a PSH with a low complication and recurrence rate.
