BACKGROUND AND AIMS: Despite evidence that most nonmalignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a nonmalignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We describe 30-day postoperative morbidity and mortality and explore risk factors for adverse events in patients undergoing surgical resection for nonmalignant colorectal polyps.
METHODS: We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program. Our analysis included 12,732 patients who underwent elective surgery for a nonmalignant colorectal polyp from 2011 through 2014. We report adverse events within 30 days of the index surgery. Modified Poisson regression was used to estimate risk ratios and 95% confidence intervals.
RESULTS: Thirty-day mortality was .7%. The risk of a major postoperative adverse event was 14%. Within 30 days of resection, 7.8% of patients were readmitted and 3.6% of patients had a second major surgery. The index surgery resulted in a colostomy in 1.8% and ileostomy in .4% of patients. Patients who had surgical resection of a nonmalignant polyp in the rectum or anal canal compared with the colon had a risk ratio of 1.58 (95% confidence interval, 1.09-2.28) for surgical site infection and 6.51 (95% confidence interval, 4.97-8.52) for ostomy.
CONCLUSIONS: Surgery for a nonmalignant colorectal polyp is associated with significant morbidity and mortality. A better understanding of the risks and benefits associated with surgical management of nonmalignant colorectal polyps will better inform discussions regarding the relative merits of management strategies.
