    Abstract:
    BACKGROUND: Patients with large benign colon polyps not amenable to endoscopic removal commonly undergo resections. Polyp removal using combined endolaparoscopic surgery may be an effective alternative to bowel resection in select patients. OBJECTIVE: The aim of this study was to evaluate short-term and long-term outcomes of patients who underwent endolaparoscopy at our institution. DATA SOURCES: Medical records and a prospectively maintained database were reviewed. STUDY SELECTION: This study constituted a retrospective review of consecutive patients who underwent endolaparoscopy for benign polyps from 2003 to 2012. INTERVENTIONS: Combined endolaparoscopic surgery was performed. MAIN OUTCOME MEASURES: The primary outcomes measured were success rate, rate of recurrence, rate of malignancy, length of stay, and complication rate. RESULTS: A total of 75 patients were taken to the operating room with the intention of endolaparoscopy. The most common indications were large polyp size and difficult location. Based on intraoperative findings, 10 patients were suspected of having cancer and underwent immediate laparoscopic colectomy. Of 65 attempted cases, 48 patients (74%) underwent successful combined endolaparoscopic surgery. Median follow-up time was 65 (8-87) months. Patients in whom combined endolaparoscopic surgery was unsuccessful were converted to colectomy (2 open, 15 laparoscopic). Two patients were converted because of concerns of cancer and 15 because of technical difficulties. Median operative time for successful endolaparoscopy was 145 (50-249) minutes. The complication rate was 4.4% (2/48). Median length of stay was 1 (0-6) day for endolaparoscopy vs 5 (3-19) days for those converted to colectomy. Median polyp size was 3 (1.0-7.0) cm. One patient was found to have cancer on final pathology, but refused to have further surgery. Sensitivity and specificity of predicting malignancy based on clinical findings were 33% (4/12) and 98.5% (64/65). Four of 5 patients who had recurrence (10%) after endolaparoscopy had complete endoscopic polypectomy. One patient required delayed laparoscopic colectomy for a second recurrence. LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: Combined endolaparoscopic surgery appears to be a safe and effective alternative to colectomy in all parts of the colon in patients who have benign polyps not removable with colonoscopy alone.
