Ideal timing of early cholecystectomy for acute cholecystitis: An ACS-NSQIP review.

Background: Current guidelines fail to specify optimal timing of early cholecystectomy for acute cholecystitis. We hypothesized delaying operation past hospital day (HD) 2 would result in increased 30-day morbidity and mortality.

Methods: The ACS-NSQIP database was queried from 2012 to 2015 for all cholecystectomies for acute cholecystitis from HD 1-7.

Results: Delay in cholecystectomy to HD 3-7 was observed in 30% of patients with acute cholecystitis. Patients undergoing operation on HD 3-7 were older with higher rates of comorbidities (median 58yrs; 66%) than HD 1 (48yrs; 51%) or HD 2 (51yrs, p < 0.001; 55%, p < 0.001). Operations on HD 3-7 had increased 30-day mortality (1.0%) and morbidity (12%) in comparison to HD 1 (0.3%, 7%) or HD 2 (0.5%, p < 0.001; 8%, p < 0.001). On multivariable analysis, HD was an independent predictor of mortality (OR 1.15, 95% CI [1.04-1.26]).

Conclusions: Acute cholecystitis should be treated with an urgent operation within 2 days of admission due to increased morbidity and mortality when delayed past HD 2.
