Robotic left colectomy and intracorporeal overlap anastomosis for descending-sigmoid cancer with da Vinci Xi® robotic platform-a video vignette.

ABSTRACT

This video vignette illustrates the application of the da Vinci Xi® robotic platform for robotic left colectomy and intracorporeal overlap anastomosis in a 51-year-old patient diagnosed with sigmoid-descending colon junction cancer. Emphasizing the advantages of robotic surgery in colorectal procedures, the video showcases a complete mesocolic excision, involving steps such as medial-to-lateral dissection, mobilization of the splenic flexure, ligation of the left colic and sigmoid arteries, and resection of an abdominal wall nodule. The presentation highlights the surgical precision and efficiency achieved, including minimal blood loss and no complications, with an operation time of 190 min. The postoperative outcome was favorable, with the patient discharged on the eighth day and subsequent management involving chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) for stage pT4bN1aM1c moderately differentiated adenocarcinoma. This case underscores the enhanced capabilities of robotic platforms in complex colorectal surgeries, particularly in achieving cytoreductive surgery (CRS) and ensuring anastomosis safety with improved R0 resection rates.
