Aim
Prior studies have demonstrated a reoperation rate ranging from 5.8 to 7.6% following colorectal surgery. However, the indications for reoperation have not been extensively evaluated. We aimed to describe the indications for reoperation and associated procedures following colorectal resection.
Methods
This is a retrospective cohort study of all patients undergoing colorectal resection at a single institution from 2003 to 2013. For patients who returned to the operating room, the primary indication was categorized into mutually exclusive categories and all procedures performed within 30 days of the initial operation were indexed. Univariate and multivariate analyses were performed.
Results
We identified 2793 patients who underwent colorectal operations, of which 407 (14.6%) were emergent. A total of 178 (6.7%) patients returned to the operating room. On multivariate analysis, emergent operation, malnutrition, corticosteroid use, and operative duration were independently associated with reoperation; independent functional status was protective. The most common indications for reoperation were anastomotic leak and bowel obstruction. The most common procedures performed were ostomy creation, bowel resection, and adhesiolysis.
Conclusions
Reoperation after colorectal surgery is a relatively common occurrence for which we have identified the risk factors, most common indications, and specific procedures performed. This knowledge will help identify areas for improvement.
