SP2.1.6 A Systematic Review of the Incidence and Predictors of Incisional Hernias in Robotic Prostatectomy

Abstract

Abstract Aims To conduct a systematic review of the literature to identify the incidence and predictors of incisional hernia (IH) following robotic prostatectomy; and to provide recommendations to reduce the risk factors for IH development post-operatively. Methods The review was performed adhering to PRISMA guidelines, using search terms pertaining to robotic prostatectomy and incidence of IH via electronic databases (MEDLINE, EMBASE and Cochrane database). All original peer-reviewed articles in English were assessed for inclusion and quality by two independent reviewers. A quantitative analysis was conducted to evaluate methodologies, patient demographics, and the incidence of IH following robotic prostatectomy. Results We included 18 studies with a total of 17,965 patients. Average age of patients was 61.83 years and with an average BMI of 27.35. A transperitoneal, 6 port technique was the commonest robotic approach. Main sites of herniation included supraumbilical and lateral ports. The estimated incidence of IH was 1.49% (95% CI 1.28 to 4.25). Studies examining risk factors found age, high BMI, previous hernia repair and wound infections to be contributory to IH development. Only 6 studies reported surgical repair of IH with 3 patients requiring emergency operations. 5 studies reported reduction in IH following modifications in surgical technique. Conclusions Incisional hernias following robotic prostatectomy are a rare complication which can result in high patient morbidity. Our review demonstrated a variable incidence rate with increasing age and high BMI as common potential risk factors. Prevention strategies can result in reduction of IH; however, the studies were heterogenous with inconsistent data quality.
