Abstract
BACKGROUND: Up to 20% of patients with colorectal cancer present with obstruction. The goal of this study was to compare the short-term outcomes of patients with obstructing colon cancer who underwent resection and primary anastomosis with or without proximal diversion. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program Procedure Targeted Colectomy databases from 2012 to 2014 were reviewed. Patients undergoing colorectal resection with or without diverting ostomy for obstructing colorectal cancer were analyzed. Propensity score-matched cohorts of diverted and nondiverted patients were created accounting for patient characteristics. The primary outcomes were 30-day mortality, postoperative complications, and readmission. RESULTS: There were 2,323 patients (92%) with no proximal diversion and 204 patients (8%) with proximal diversion. In univariate analysis, patients with colorectal resection with diversion were significantly more likely to have any complication (P = .001), sepsis (P = .01), and blood transfusion (P = .001). Diversion patients were also significantly more likely to be readmitted to the hospital within 30 days of the index procedure (P = .02). Proximal diversion was associated with any complication (P = .01), failure to wean off ventilator (P = .05), and longer length of stay (P = .01) in matched cohorts. CONCLUSIONS: Proximal diversion in the setting of obstructive colorectal cancer is associated with higher rates of any complication, deep wound infection, sepsis, and readmission. Surgeons who perform a primary anastomosis with diversion for obstructing colorectal cancer should take into account the significant risk for postoperative complications.
