Background
Previous studies have reported that performing same-day laparoscopic cholecystectomy (LC) for acute cholecystitis is superior to delayed elective cholecystectomy. While this practice is ideal, it requires significant hospital resources. We sought to determine whether prolonged preoperative length of stay (LOS) was associated with increased operative time and length of stay in patients with acute cholecystitis.
Methods
This was a retrospective chart review of patients treated for symptomatic gallstone disease at a large municipal hospital between September 2012 and November 2013. Inclusion criteria were patients age ≥18 years who underwent same-admission cholecystectomy and had a diagnosis of cholecystitis on pathology. Medical records were reviewed and relevant data points were collected. Univariate and multivariate regressions were performed to assess the correlation between time to operation (<36hrs (no delay) or > 36hrs (delay)) and the main outcomes (operative time and total length of stay).
Results
88 patients met all criteria for inclusion. Patients with > 36hrs wait prior to surgery had a total length of stay twice as long as patients with < 36hrs wait (152 vs 8.3; p=0005). Operative times were similar for patients in the delay and no delay groups (2.38 vs 2.01; p=0.1833). The mean (SD) preoperative LOS was 76.2 (±48.6) hours, the mean operative time was 2.3 (±1.1) hours and the mean postoperative LOS was 60.3 (±60.1) hrs. The average total LOS was 136 (±79.8) hrs. There was no association between preoperative and postoperative LOS. These findings remained significant when adjusted for age, sex, radiologic findings, number of preoperative tests and pathology.
Conclusion
Increased preoperative LOS is associated with a statistically but not clinically significant increase in operative time. It was associated with an increased total LOS for patients with acute cholecystitis who undergo same-admission cholecystectomy. The increase in total LOS was associated solely with preoperative LOS.
