Abstract

PURPOSE: This study was undertaken to determine the risks of cancer in unresectable polyps and to compare the short-term outcome of laparoscopic colectomy with that of open colectomy for benign polyps. METHODS: A retrospective review of all patients (n = 165) undergoing colectomy for an adenoma unresectable at colonoscopy was performed on patients collected in a prospective database. One hundred four patients underwent laparoscopic colectomy and 61 underwent open colectomy between 1991 and 2003. Follow-up was 7 to 155 (median, 90) months. RESULTS: In the laparoscopic group, 85% of the patients underwent a right colectomy and 15% underwent a left colectomy or a sigmoidectomy. Conversion to open colectomy occurred in 4.8% of the cases. Complications occurred in 14% of the patients, including 1 death. The median length of stay was 4 days. At final pathology, cancer was diagnosed in 15 patients: stage I in 8 patients, stage II in 5, and stage III in 2. In the open colectomy group, 69% of the patients underwent right colectomy. The complication rate reached 23% (P = .13), including death in 2 patients. The median length of stay was 6 days (P < .01). Cancer was diagnosed in 6 patients: stage I in 5 patients, and stage II in 1. Proximal (10 cm) and distal (13 cm) margins, lymph nodes harvest (9), incidence of cancer (13%), and high-grade dysplasia (22%) were similar between groups. There were no local recurrences, trocar site implants, or deaths due to cancer. CONCLUSION: Laparoscopic colectomy for polyps unresectable at colonoscopy is safe. Oncologic resection of the colon should be performed for all colonoscopically unresectable polyps due to the risk of cancer.
