Surgical Laparoscopy, Endoscopy & Percutaneous Techniques: August 2018 - Volume 28 - Issue 4 - p 245-249 doi: 10.1097/SLE.0000000000000552 Buy Metrics Abstract In this study, perioperative and short-term postoperative results of totally robotic versus totally laparoscopic rectal resections for cancer were investigated in a comparative manner by considering risk factors including obesity, male sex, and neoadjuvant treatment. In addition to overall comparison, the impact of sex, obesity (body mass index ≥30 kg/m2), and neoadjuvant treatment was assessed in patients who had a total mesorectal excision (TME). Operative time was longer in the robotic group (P<0.001). In obese patients who underwent TME, the mean length of hospital stay was shorter (7±2 vs. 9±4 d, P=0.01), and the mean number of retrieved lymph nodes was higher (30±19 vs. 23±10, P=0.02) in the robotic group. Totally robotic and totally laparoscopic surgery appears to be providing similar outcomes in patients undergoing rectal resections for cancer. Selective use of a robot may have a role for improving postoperative outcomes in some challenging cases including obese patients undergoing TME. Copyright © 2018 Wolters Kluwer Health, Inc.
