To investigate the feasibility and safety of robotic colorectal resection with hand-sewn anastomosis of the digestive tract and nature orifice specimen extraction.

The clinical date of 10 patients diagnosed with colorectal tumor who were treated with robotic colorectal resection with hand-sewn anastomosis of the digestive tract and nature orifice specimen extraction from May 2020 to July 2022 at the Division of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People’s Hospital were retrospectively studied.

There were 4 males and 6 females, with the age range from 33 to 82 years, received robotic colorectal resection with hand-sewn anastomosis of the digestive tract and nature orifice specimen extraction. The surgical specimen is removed through the rectum. The median operative time was 120(ranged 100 to 190)minutes. The intraoperative blood loss was 40(ranged 10 to 100)ml and there was no intraoperative blood transfusion. The median postoperative hospital stay was 10(ranged 8 to 18)days. There were no transit open surgery, re-operation and mortality. Perioperative complications (Clavien-Dindo grade): 1 case of grade Ⅲ, 2 cases of grade Ⅱ, 1 case of grade Ⅰ; 1 case developed anastomotic leakage, successful through conservative treatment.

Robotic colorectal resection with hand-sewn anastomosis of the digestive tract and nature orifice specimen extraction was effective and safe to treat colorectal tumor with the improvement of intra-abdominal anastomosis technology.
