Background: Large colonic polyps or polyps that lie in anatomical locations that are difficult to access at endoscopy may not be suitable for endoscopic resection and therefore may require partial colectomy. This approach eradicates the polyp and allows an oncologic resection should the polyp prove to be malignant. The purpose of this study was to assess outcomes of a laparoscopic approach for the management of these polyps. Methods: Patients referred for laparoscopic colectomy for colonic polyps were identified from the prospective colorectal laparoscopic surgery database. Demographics, operative details, and final pathology were reviewed. Results: Fifty-one consecutive patients (27 male) with a mean age of 68 ± 11.4 years, ASA classification (1/2/3/4) of 0/21/27/3, and body mass index (BMI) of 26.5 ± 4.9 were identified. Right (RHC) and left (LHC) colectomy was performed for 39 right and 12 left colonic polyps. Mean operating time (OT) was 87 ± 30 min (81 for RHC, 105 for LHC) and mean hospital stay was 3.1 ± 1.9 days. There were six complications (17.7%), including anastomotic leak (n = 1), small bowel obstruction (n = 2), abscess (n = 1), and exacerbation of preexisting medical conditions (n = 2). Four patients were readmitted (7.8%); one required CT scan-guided abscess drainage (1.9%) and two required reoperation (3.9%). Five patients (9.8%) were converted because of adhesions (n = 3), obesity (n = 1), and inability to identify the area that was tattooed at colonoscopy (n = 1). Mean polyp size was 3.1 cm, and pathology revealed tubular (n = 14), tubulovillous (n = 33) and villous adenoma (n = 2), pseudopolyp (n = 1), and prolapse of the appendix into the cecum mimicking an adenoma (n = 1). High-grade dysplasia was seen in four tubular (33%) and five tubulovillous adenomas (15.5%). Adenocarcinoma not identified at colonoscopy was found in 11 polyps (20%), 9 tubulovillous (27.8%) and both villous adenomas (100%). Conclusions: Large colonic polyps unresectable at colonoscopy are associated with a high rate of unsuspected cancer. This requires a formal colectomy rather than transcolonic polypectomy. Laparoscopic colectomy offers safe and effective management of these polyps with the benefits of accelerated postoperative recovery.
