Treatment of acute cholecystitis is still under debate. The aim of this study was to evaluate the efficacy of early laparoscopic cholecystectomy (ELC) in comparison with conservative treatment followed by delayed laparoscopic cholecystectomy (DLC) in the management of acute cholecystitis. This prospective comparative study involved two groups of patients presenting with acute cholecystitis within 72 hours of the onset of symptoms. ELC was performed in 82 consecutive patients, whereas DLC was performed in 87 patients who previously underwent medical treatment. Surgical variables, hospital stay, and postoperative morbidity were evaluated in both groups. Time of surgery and conversion rate were lower in the ELC group. Postoperative morbidity was similar in both groups. Overall hospital stay was shorter in the ELC group. ELC within 72 hours of the onset of acute cholecystitis is a safe procedure with better results than DLC in terms of surgical timing, conversion rate, and hospital stay.
