title: Robotic colorectal surgery: first 50 cases experience.
abstract: OBJECTIVE
  Laparoscopic colorectal surgery is believed to be technically and oncologically feasible. However, some limitation of traditional laparoscopic surgery may cause difficulties. Robotic-assisted surgery may overcome these pitfalls.
  
  
  METHODS
  From December 2005 to July 2007, 50 patients were selected for robotic-assisted colorectal resection mainly for cancer.
  
  
  RESULTS
  Of the 50 patients enrolled, 32 (64 percent) were men and 18 (36 percent) were women. Their mean age was 66.7 (range, 37-92) years. The American Society of Anesthesiologists' (ASA) class distribution was 13 (26 percent) ASA I, 24 (48 percent) ASA II, 12 (24 percent) ASA III, and 1 (2 percent) ASA IV. Forty-four patients suffered from cancer and six patients from benign disease. Amongst the cancer patients, 3 percent were at UICC (International Union Against Cancer) Stage 0, 36 percent at UICC Stage I, 24 percent at Stage II, 28 percent at Stage III, and 9 percent at Stage IV. The global conversion rate was 4 percent. The mean operative time was 338.8 minutes. It decreased as the experience increased (419 minutes in the first 20 cases vs. 346 minutes in the last 30 cases; P = 0.036). As a gross comparison, the results of a coeval standard laparoscopy group of patients were shown.
  
  
  CONCLUSIONS
  Robotic laparoscopic colon surgery is feasible and safe. A longer operating time is needed.
