title: Dynamic article: combined endoscopic-laparoscopic surgery for complex colonic polyps: postoperative outcomes and video demonstration of 3 key operative techniques.
abstract: BACKGROUND
  Combined endoscopic-laparoscopic surgery is a novel technique that can be used to avoid bowel resection for complex colon polyps that are not amenable to colonoscopic resection.
  
  
  OBJECTIVE
  The aim of this study was to evaluate the safety and outcomes of combined endoscopic-laparoscopic surgery for complex colonic polyps.
  
  
  METHODS
  This study is a retrospective review of consecutive combined endoscopic-laparoscopic surgeries.
  
  
  METHODS
  This study was conducted at a single institution.
  
  
  METHODS
  All patients that underwent combined endoscopic-laparoscopic surgery for a complex colonic polyp at our center from October 2009 to October 2013 were followed. Each patient's lesion was assessed by a therapeutic endoscopist before referral for combined endoscopic-laparoscopic surgery, and was deemed unresectable based on size, broad base, or location of the polyp.
  
  
  METHODS
  Intraoperative and postoperative complications, length of hospital stay, and recurrence were the primary outcomes measured.
  
  
  RESULTS
  Thirty consecutive patients underwent combined endoscopic-laparoscopic surgery. Twenty (66.7%) patients underwent laparoscopic-assisted colonoscopic polyp excision (10 of these excisions were facilitated by Endoloop placement at the polyp base), 9 (30%) patients underwent colonoscopic-assisted laparoscopic cecectomy, and 1 (3.3%) patient was converted from a colonoscopic-assisted laparoscopic cecectomy to a laparoscopic ileocolic resection. The median length of hospital stay was 2 days (range, 1-16). Twenty-nine (96.7%) of the final pathology results were benign, with 10 (33.3%) showing high-grade dysplasia. One (3.3%) final pathology result was positive for a well-differentiated adenocarcinoma. This patient subsequently underwent a laparoscopic right hemicolectomy and chemotherapy for node-positive disease. One (3.3%) patient experienced a recurrent benign polyp at the previous excision site, which was removed by colonoscopy. The time to detection of recurrence was 274 days.
  
  
  CONCLUSIONS
  This study looked at a small group of patients, over a short follow-up period. However, all consecutive patients were captured, and there were no losses to follow-up.
  
  
  CONCLUSIONS
  Combined endoscopic-laparoscopic surgery for complex benign colonic polyps is a safe procedure, with good clinical outcomes and low recurrence rates.
