Extent of unnecessary surgery for benign rectal polyps in the Netherlands.

Minimally invasive techniques are available to safely and efficaciously remove even the largest rectal polyps. This study aimed to investigate the magnitude of cases still referred for radical rectal surgery and the reasons for these referrals and to perform a re-evaluation of cases potentially suitable for endoscopic therapy. A retrospective analysis of data from the Dutch Pathology Registry (Pathologic Anatomic Nationwide Automated Archive) was performed using the records of patients who underwent major surgical treatment for a histologically proven benign rectal polyp between 2005 and 2014 in the Netherlands. In a representative subset of 7 hospitals, detailed analysis was performed. An expert panel of 3 endoscopists reassessed all patient data to judge whether endoscopic treatment would have been a reasonable alternative. In the last decade 575 patients, and 56 patients in the subset of hospitals, were referred for major rectal surgery for a benign rectal polyp in the Netherlands. The number of radical resections declined over the years but stabilized in the last years. The main reasons for surgery were polyp size (34%), suspicion of malignancy (34%), and transanal endoscopic microsurgery failures (20%). In community hospitals, referrals for surgery were relatively more prevalent compared with academic hospitals (P < .01). Thirty-nine percent of patients had perioperative adverse events, and 1 patient (1.8%) died. Seventy-three percent of cases were assessed as "probably feasible" for endoscopic therapy. Over the last 10 years the rate of radical rectal surgery for a benign polyp declined. However, a significant subgroup of patients was still referred for invasive surgery at the cost of high morbidity and mortality. Referral to an expert endoscopist may avoid unnecessary surgery in most cases. Copyright © 2017 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc. All rights reserved.
