Robotic parastomal hernia repair: A single-center cohort study.

Abstract

Parastomal hernia is a common occurrence following stoma construction, necessitating surgical intervention in symptomatic cases. This study presents a comprehensive analysis of Robotic-Assisted Parastomal Hernia Repair (r-PSHR), utilizing the Da Vinci Xi™ Surgical System. Retrospective analysis was conducted on patients undergoing r-PSHR at a high-volume center. Surgical variables, complications, and recurrence rates were assessed. The primary technique involved a modified Sugarbaker intraperitoneal onlay mesh. Eighty-six patients underwent r-PSHR, predominantly females (59.3%), with mean age 60.8 years. Mean BMI was 31.0. Most patients were classified as ASA 2 (31.4%) or ASA 3 (65.1), with 64.6% having no prior PSH repair. Index procedures primarily involved laparoscopic colonic resections (27.8%) and open abdominoperineal resections (27.8%). Parastomal hernias were mainly associated with end ileostomy (50%) and end colostomy (47.7%). A hybrid modification was required in 22.1% of cases, with only one conversion to open repair. Mean operative time was 257 min. Thirty-day morbidity was 40.7% and includes ileus (24.4%), deep surgical-site infections (7.0%), acute kidney injury (5.8%), and sepsis (5.8%). Grade IIIB complications occurred in 5.8% of cases. Thirty-day readmissions were observed in 19.8% of cases. There were five cases (5.8%) of recurrence within 15 months post-surgery. This study highlights the effectiveness of r-PSHR in managing parastomal hernia. R-PSHR shows promising outcomes with an acceptable post-operative occurrence profile and a favorable recurrence rate.
