A prospective study of robotic rectal surgery for carcinoma rectum assessing the functional and oncological outcomes: Hype or hope?

Abstract

661Background: Robotic surgical systems have dramatically changed minimally invasive surgery as they could potentially address limitations of laparoscopic rectal surgery. This prospective observational study is conducted to evaluate the safety, technique, and outcomes (operative, postoperative,functional and oncological long term) of robotic-assisted rectal surgery for carcinoma rectum in the Indian set up. Methods: This was a prospective observational study conducted between 2010 and 2018, including 135 patients, diagnosed of rectal carcinoma. Patients underwent robotic rectal cancer surgery in form of either low anterior resection (LAR) or abdominoperineal resection (APR). Intraoperative, postoperative data were analysed. Results: Out of 135 patients, 67.5% were male, aged between 34-80 years, 85% had ECOG 0. All patients had adenocarcinoma rectum, with 15% mid rectum and 55% in lower rectum. 85% had stage III disease. 77.5% had received neoadjuvant chemoradiation. 82.5% had LAR and 17.5% APR. Average o...
