Fluorescence ureteral navigation for colorectal cancer invading seminal vesicle with peritoneal dissemination – A video vignette

Abstract

Laparoscopic extended colectomy is a standard procedure for hepatic flexure tumours. Complete mesocolic excision improves specimen quality and lymph node yield [1-3]. In the case of cT4b colon cancer, the laparoscopic procedure may be challenging due to the involvement of other visceral organs and also cost consuming due to the use of multiple endo-staplers.Video S1 demonstrates a step by step approach to laparoscopic extended colectomy with complete mesocolic excision for a hepatic flexure tumour involving the jejunum with emphasis on radicality of the surgery and cost reduction.

Fluorescence urethral navigation for transperineal minimally invasive abdominoperineal resection for rectal cancer

“…Video S1 shows Tp‐APR for rectal cancer after radiotherapy using a near‐infrared ray catheter fluorescent ureteral catheter (NIRFUC). This catheter's built‐in NIR fluorescent resin enables ureteral visualization under near‐infrared observation 5–7 . We inserted the NIRFUC preoperatively.…”
