title: Initial experience of reduced port surgery using a two-surgeon technique for colorectal cancer.
abstract: BACKGROUND
  With the decreasing number of surgeons on surgical teams, reduced port surgery (RPS) operations have become popular. We herein present our initial experience with RPS, which was successfully performed using a two-surgeon technique. A retrospective analysis was performed to compare the two-surgeon technique with conventional laparoscopic colectomy and evaluate its efficacy.
  
  
  METHODS
  A total of 535 patients were eligible among 749 registered patients. Conventional multiport laparoscopic colectomy with three surgeons and RPS using the two-surgeon technique with a surgeon and surgeon's assistant were performed in 429 and 106 cases, respectively. The patient characteristics, short-term outcomes (including intraoperative and postoperative findings) and pathological results were recorded and analyzed.
  
  
  RESULTS
  The two groups were similar with respect to age, gender, BMI, history of abdominal surgery, depth of tumor invasion and TNM classification. Reconstruction via extracorporeal functional end-to-end anastomosis was performed in a significantly higher number of patients in the two-surgeon technique group (74 %) than in the conventional laparoscopic colectomy group (57 %). Furthermore, the mean operative time in the two-surgeon technique group (117.9 min) was significantly shorter than that observed in the conventional laparoscopic colectomy group (170 min), and the median postoperative hospital stay was significantly shorter in the two-surgeon technique group (6 days) than in the conventional laparoscopic colectomy group (7 days). There were no major postoperative complications. The final TNM stage was similar in both procedures.
  
  
  CONCLUSIONS
  RPS using the two-surgeon technique compares favorably with conventional laparoscopic colectomy and is considered to be a safe and successful procedure.
