Day versus night laparoscopic cholecystectomy for acute cholecystitis: A comparison of outcomes and cost.

Background: Recent studies have suggested higher complication and conversion to open rates for nighttime laparoscopic cholecystectomy (LC) and recommend against the practice. We hypothesize that patients undergoing night LC for acute cholecystitis have decreased hospital length of stay and cost with no difference in complication and conversion rates.

Methods: A retrospective review of patients with acute cholecystitis who underwent LC from October 2011 through June 2015 was performed.
