Robotic Colorectal Surgery Learning Curve and Case Complexity

To understand the role of case complexity in the learning curve for robotic colorectal surgery. Sixty-two patients who underwent robot-assisted colorectal surgery were retrospectively reviewed. Each case was assigned a category of complexity ranging from I to IV. Overall, groups and categories of segmental colectomy, rectopexy, and proctectomy for cancer were analyzed according to case volume. Forty-eight patients who underwent similar laparoscopic cases during the same period were also reviewed for comparison. Level I complexity cases were identified in 30% of the first 15 cases compared to 3% after the first 15 cases (P
