Incisional Hernia After Transperitoneal Robot-assisted Radical Prostatectomy: A Call for Greater Awareness Among...

Area of Science:

• Urology
• Surgical Oncology
• Abdominal Wall Surgery

Background:

• Incisional hernia (IH) is a recognized complication of transperitoneal robot-assisted radical prostatectomy (RARP).
• As RARP becomes a standard procedure, understanding its specific risk factors is crucial for improving patient outcomes in prostate cancer treatment.

Purpose of the Study:

• To determine the prevalence of incisional hernias at the supraumbilical extraction site one year after transperitoneal RARP.
• To identify independent risk factors associated with the development of IH following this procedure.

Main Methods:

• A cohort of 629 patients undergoing transperitoneal RARP with supraumbilical specimen extraction (2020-2024) across three French academic centers was analyzed.
• Prevalence of IH at 1-year follow-up was the primary endpoint.
• Multivariable analysis was employed to identify independent predictors of IH.

Main Results:

• The overall prevalence of IH at 1 year was 12.1% (76 out of 629 patients), with 70% requiring surgical repair.
• Independent risk factors identified included higher body mass index, smoking, and postoperative parietal abscess.
• The study suggests a potential underdiagnosis of IH, with implications for bowel obstruction and chronic pain.

Conclusions:

• Incisional hernia is a frequent complication of transperitoneal RARP, often under-reported.
• Optimizing fascial closure techniques and potentially reconsidering supraumbilical extraction site location may mitigate IH risk.
• Systematic imaging for high-risk individuals could enhance early IH detection and management.
