Combined robotic and cystoscopic surgery for rectal cancer invading urinary bladder.

ABSTRACT: Although the application of laparoscopic rectal surgery has been widely accepted by accumulated evidence, it remains technically difficult in some cases of obesity, narrow male pelvis, bulky tumors, or involvement of adjacent organs. After robotic rectal surgery has been covered by the health insurance system in Japan since April 2018, we have employed robotic rectal surgery for an increasing number of cases by taking advantages of its 3D vision and wrist function. When a colorectal cancer involves the urinary bladder, the surgical treatment of choice is an anterior resection with en bloc (partial or total) bladder resection, depending on the site and extent of bladder involvement. In the attached video, robotic surgery was conducted with the aid of intraoperative cystoscopy, which resulted in curative resection with negative margin. Given that the robotic system provides excellent stability and dexterity for bladder reconstruction, the robotic approach can be technically suitable for locally advanced T4 colorectal cancer with urinary involvement.
