Avoiding surgery in patients with colorectal polyps.
OBJECTIVE
Colonic polyps are sometimes difficult to remove endoscopically and are referred for surgical resection. This study was performed to determine how many polyps referred for surgery could actually be managed endoscopically.


METHODS
An endoscopic database with data entered prospectively and consecutively was used to identify patients referred for surgery for a colonic polyp. Rectal polyps were excluded. All patients underwent colonoscopy before surgery to see if the polyp could be managed endoscopically. Cases were reviewed to see the method and outcome of treatment.


RESULTS
The study population consists of 58 patients referred for surgical resection of a colorectal polyp. Endoscopic polypectomy was initially successful in 48. Five of the 48 needed surgery later for a final success rate of 43/58 avoiding surgery. There were no deaths, four complications of endoscopic polypectomy (three bleeds, one post-polypectomy syndrome) and two patients had complications of surgery (one splenic injury, one ventral hernia). Polyps ranged in size from 1.5 cm to 8.0 cm. Seven polyps contained invasive cancer (three needing surgical resection), eight contained intramucosal cancer (one operated) and 11 had severe dysplasia (three operated). Rate of persistent polyp was 16/37 at first follow up, 7/23 at second, 1/14 at third and 0/8 at fourth.


CONCLUSIONS
Most polyps referred for surgical resection were successfully managed endoscopically. Patients with colonic polyps that are difficult or potentially dangerous to remove endoscopically should be sent for a second opinion before surgery is performed.
