Abstract
Background
Up to 50% of patients with acute complicated diverticulitis require operative management on their index admission. There is ongoing debate as to whether primary anastomosis with diverting ileostomy versus a Hartmann’s procedure is the optimal surgical approach for these patients. This study aims to compare postoperative complications in patients undergoing either Hartmann’s procedure or primary anastomosis and diverting ileostomy for perforated diverticulitis using recent National Inpatient Sample data.
Methods
Patients who underwent either primary anastomosis with diverting ileostomy or Hartmann’s procedure for acute complicated diverticulitis from the 2015 to 2019 NIS database sample were included. Primary outcomes were postoperative in-hospital mortality and morbidity. Secondary outcomes were postoperative cause-specific complications, total admission cost, and length of stay (LOS). Univariate and multivariate regression were utilized to compare the two operative approaches.
Results
Overall, 642 patients underwent primary anastomosis with diverting ileostomy and 4,482 patients underwent Hartmann’s procedure. There was no difference in in-hospital mortality (OR 0.93, 95%CI 0.45–1.92, p = 0.84) or in-hospital morbidity (OR 1.10, 95%CI 0.90–1.35, p = 0.33). Adjusted analysis suggested shorter postoperative LOS for patients undergoing Hartmann’s procedure (MD 0.79 days, 95%CI 0.15–1.43 days, p = 0.013) and decreased total admission cost (MD $4,893.99, 95%CI $1,425.04-$8,362.94, p = 0.006).
Conclusions
The present study supports that primary anastomosis with diverting ileostomy is safe for properly selected patients presenting with complicated diverticulitis. Primary anastomosis with diverting ileostomy is associated with greater total hospitalization costs and LOS.
