Use and outcomes of emergent laparoscopic resection for acute diverticulitis

Abstract

Background: The use and outcomes of laparoscopic sigmoid resection during emergency admissions for diverticulitis are unknown.

Methods: The Nationwide Inpatient Sample was queried for colorectal resections performed for diverticulitis during emergent hospital admissions (2003-2007). Univariate and multivariate analyses including patient, hospital, and outcome variables were performed.

Results: A national estimate of 67,645 resections (4% laparoscopic) was evaluated. The rate of conversion to open operation was 55%. Ostomies were created in 66% of patients, 67% open and 41% laparoscopic. Laparoscopy was not a predictor of mortality (odds ratio [OR] =.70; confidence interval [CI], .32-1.53). Laparoscopy predicted routine discharge (OR = 1.31; CI, 1.06-1.63) and a decreased length of stay (absolute days = -.78; CI, -1.19 to -.37). There was no difference in the cost of hospitalization between the 2 groups (P = .45).

Conclusions: In acute diverticulitis, urgent laparoscopic resection decreases the length of stay. However, it is associated with a high conversion rate, no cost savings, and no difference in mortality.
