Mesentery-Sparing Technique: a New Intracorporeal Approach for Urinary Diversion in Robot-Assisted Radical Cystectomy

Area of Science:

• Urology
• Surgical Innovation
• Oncology

Background:

• Robotic-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) carries risks of morbidity and mortality.
• Ischemia in the ileal anastomosis and diversion loop are key concerns.

Purpose of the Study:

• To present an alternative RARC with ICUD technique preserving mesenteric vascularization.
• To minimize ischemic complications in the intestinal segment used for ICUD.

Main Methods:

• A cohort study of 31 patients undergoing RARC with ICUD using a mesentery-sparing technique.
• Data collected on intraoperative and postoperative complications, including ileus and hospitalization duration.

Main Results:

• No intraoperative or postoperative complications directly linked to the mesentery-sparing technique were observed.
• Median hospitalization was 6 days; 19% experienced postoperative ileus requiring parenteral nutrition.
• Minor complications occurred in 27.6% and major complications in 20.6% of patients.

Conclusions:

• The mesentery-sparing technique is a viable alternative for RARC with ICUD.
• This approach effectively preserves intestinal segment vascularization and reduces complication risks.
