Morbidity and mortality after surgery for nonmalignant colorectal polyps.


ABSTRACT:

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.
