Methods: This prospective, randomized controlled trial enrolled patients diagnosed with moderate to severe acute cholecystitis who underwent PCC. Clinical manifestations and laboratory parameters were monitored for 72 hours following PCC insertion. Patients demonstrating clinical or laboratory improvement were subsequently randomized into two groups: early LC and delayed LC. * Early LC group: Laparoscopic cholecystectomy was performed during the same hospitalization. * Delayed LC group: Laparoscopic cholecystectomy was performed more than 6 weeks after PCC insertion. The primary endpoint/outcome is comprehensive complication index (CCI) from PCC and LC. Secondary endpoints include Nasaar Difficulty Scoring, length of hospital stay, rate of subtotal cholecystectomy, rate of conversion to open cholecystectomy and incidence of bile duct injury. Results and Discussion: The results of this study will provide valuable insights into the timing of LC following PCC and may influence future treatment protocols for moderate and severe acute cholecystitis. By assessing the feasibility and safety of early LC after PCC insertion, the ESCAPE trial aims to reduce the burden of PCC-related complications and optimize patient outcomes.
