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.
Design:
This study is a retrospective review of consecutive combined endoscopic-laparoscopic surgeries.
Setting:
This study was conducted at a single institution.
Patients:
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.
Main Outcome Measures:
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.
Limitations:
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.
