Abstract: BACKGROUND: There is an increasing preference for early laparoscopic cholecystectomy (ELC) as compared to delayed LC (DLC) in the management of acute cholecystitis (AC). Conversion to open cholecystectomy (LOC) remains an important outcome. We aim to compare ELC and DLC outcomes and identify LOC predictors. METHODS: Retrospective analysis of 466 patients who underwent LC for AC from June 2010 to June 2015 was performed. Patients were divided into ELC and DLC groups, defined as LC performed within 7 days and between 4 to 24 weeks of symptom onset, respectively. Peri-operative outcomes and predictors for LOC were analyzed. RESULTS: Conversion rates were comparable [ELC, 8.6% vs. DLC, 8.0%] (P=0.867). While median operative time was longer in ELC (101.5 min [83.0-130.1]) than DLC (88.0 min [62.3-118.8]) (P<0.001), intraoperative (ELC, 1.9% vs. DLC, 3.0%; P=0.541) and postoperative morbidity (ELC, 13.5% vs. DLC, 12.5%; P=0.688) was comparable. Median total length of stay (LOS) was shorter in ELC (4 days [3-6]) than DLC (5 days [4-9]) (P<0.001). Univariate analysis showed increased age (LC, 57 [45-66] vs. LOC, 60 [56-72]; P=0.016), presence of comorbidities (LC, 69.0% vs. LOC, 87.8%; P=0.009), previous abdominal surgery (LC, 6.1% vs. LOC, 17.1%; P=0.014), fever (P=0.001), Murphy's sign (P=0.005) and lower albumin (LC, 42.0 [39.0-45.0] vs. LOC, 40.0 [36.0-43.0]; P=0.003) to be predictors for LOC. CONCLUSIONS: ELC provides shorter LOS and eliminates the risk of gallstone-related morbidity while awaiting surgery. It should be advocated for patients with AC. The presence of comorbidities, increased age, previous abdominal surgery and low albumin are predictors for conversion. � 2017 EDIZIONI MINERVA MEDICA.
