One Hundred and Two Consecutive Robotic-Assisted Minimally Invasive Colectomies-An Outcome and Technical Update

The objective of this study was to review 102 consecutive robotic colectomies at our institution. We evaluated the 8-year experience of one surgeon (DLC) in Peoria, IL using the da Vinci system. An IRB-approved retrospective review was performed. Results were compared with the literature. Changes in technique over the years were evaluated. One hundred and two robotic colectomies, right (59) and sigmoid (43), were performed. Mean age is 63.5 years and mean BMI 27.4 kg/mA(2). Preoperative indications are polyps (53), diverticular disease (27), cancer (19), and carcinoid (3). Mean total case time (TCT) for all cases is 219.6 +/- 45.1 (50-380) min, and mean robot operating time (ROT) is 126.6 +/- 41.6 (12-306) min. Operative times for Right: Port setup time (PST) 32.4 +/- 10.5 (20-64) min, ROT 145.2 +/- 39.6 (53-306) min, TCT 212.3 +/- 46.4 (50-380) min; times for sigmoid: PST 31.2 +/- 9.6 (10-57) min, ROT 101.2 +/- 29.2 (12-165) min, TCT 229.7 +/- 41.6 (147-323) min. Median length of stay for all patients is 3 (2-27) days. The overall complication rate is 18.6%, the overall conversion rate 8.8%, and the anastomotic leak rate is 0.98%. Residents PGY 1-5 participated in 61 cases (59.8%). We report our updated procedural sequence and technical alterations. Experience has allowed residents to evolve to be primary surgeons. We add our results to the current robotic literature.
