title: Single-port access laparoscopic radical left colectomy in humans.
abstract: BACKGROUND
  Transumbilical single-port access (SPA) surgery is a rapidly evolving field that combines in part the cosmetic advantage of natural orifice transluminal endoscopic surgery (NOTES) with the ability to perform the operation with standard laparoscopic instruments. We report our experience with the first transumbilical single-port access radical left colectomy conforming to surgical oncologic principle and minimally invasive colectomy technique.
  
  
  METHODS
  Umbilical single-port access (embryonic natural orifice transluminal endoscopic surgery) left colectomy was performed in a patient with sigmoid colon adenocarcinoma in situ. During the same procedure, a single-port access cholecystectomy was performed for chronic cholecystitis.
  
  
  RESULTS
  Transumbilical single-port access radical left colectomy was feasible with conventional laparoscopic instruments. A 39-cm pathologic specimen with sufficient surgical margins and lymph nodes (34) was resected. Final diagnosis revealed an adenocarcinoma in situ. Operative time for left colectomy and cholecystectomy was 213 minutes. No intraoperative or postoperative complications were recorded.
  
  
  CONCLUSIONS
  Single-port access radical left colectomy is feasible when performed by experienced laparoscopic surgeons. Carcinologic surgical principles can be respected using this colectomy technique. Single-port access left colectomy may have a clinical advantage over natural orifice transluminal endoscopic surgery in offering the safety of laparoscopic colectomy. It has yet to be determined whether or not this approach would offer patient benefits, except in cosmesis, compared with standard laparoscopic left colectomy.
