Prophylactic mesh used in ileal conduit formation following radical cystectomy: a retrospective cohort.
PURPOSE: Given the difficulty of durable repairs, there is continued interest in hernia prevention. One emerging prevention technique for parastomal hernias is prophylactic mesh placement, whereby mesh is inserted during the index procedure as hernia prophylaxis. We evaluated our experience using prophylactic mesh when creating an ileal conduit. METHODS: We retrospectively reviewed patients undergoing robotic cystectomy with ileal conduit from 6/2010 to 8/2017. Patient demographics and operative/perioperative outcomes were documented. We evaluated hernia recurrence using postoperative computed tomography scanning or physical exam. Prophylactic mesh was inserted at the operating surgeon's discretion using a synthetic resorbable or biologic mesh. RESULTS: During the study period, 38 patients underwent robotic-assisted cystectomy with ileal conduit formation. Average patient age was 68 years, with 28 (74%) male and 35 (92%) Caucasian patients. Three patients (8%) required conversion to open, and one patient (3%) had a concomitant colorectal resection. Thirty-one (88%) patients had postoperative computed tomography scanning. Prophylactic mesh was used in 18 patients (47%) in a retrorectus position. Of these, 15 (83%) patients had synthetic resorbable mesh and 3 (17%) patients had biologic mesh. At average follow-up of 21 months, one hernia recurred (5%) in a patient without mesh placement at the time of ileal conduit. At an average follow-up of 11 months, there have been no recurrences and no mesh-related complications in the prophylactic mesh group. CONCLUSIONS: Using prophylactic mesh in ileal conduit, creation is feasible and may decrease the parastomal hernia formation rate. Further study of using synthetic resorbable and biologic meshes for hernia prophylaxis is warranted.
