IntroductionEarly laparoscopic cholecystectomy (ELC) is a treatment option for acute cholecystitis (AC). However, the timing of ELC is controversial. Delayed laparoscopic cholecystectomy (DLC) continues to be a common practice. This study aims to determine the optimal timing of ELC in AC.Materials and methodsPatients who underwent surgery for AC between 2014 and 2020 were divided into three groups: immediate laparoscopic cholecystectomy (ILC), prolonged ELC (pELC), and DLC. The demographic, laboratory, radiological findings, and postoperative results of all patients were retrospectively reviewed.ResultsThe study included 178 patients, with 63 in the ILC group, 27 in the pELC group, and 88 in the DLC group. Postoperative outcomes, excluding hospital stay, were similar between the groups. The total hospital stay was significantly longer in the pELC and DLC groups (p<0.05). In addition, postoperative hospital stay was longer in the pELC group (p<0.05), and 17.7% of the patients who waited for delayed surgery experienced recurrent attacks during the interval period.ConclusionILC is recommended in AC to minimize hospital stays.
