Early Laparoscopic Cholecystectomy Versus Percutaneous Cholecystostomy Followed by Delayed Laparoscopic Cholecystectomy in Patients with Grade II Acute Cholecystitis According to Tokyo Guidelines TG18

Introduction: In the past, most patients with acute cholecystitis (AC) were treated conservatively. However, strong evidence from various studies has shown that laparoscopic cholecystectomy (LC) is safe and should be the primary treatment for AC. However, this may not be the case for all AC grades. This study aimed to compare two recommended approaches for grade II AC as outlined in the Tokyo guidelines TG18, focusing on early operative outcomes. Methods: We conducted a retrospective review of medical records for all patients diagnosed with grade II AC. The study compared patients who underwent early LC (group A, n = 130) with those who initially received percutaneous cholecystostomy (PC) followed by LC (group B, n = 90). Results: Both groups had similar Tokyo classification parameters. However, there were significant differences in baseline data, operative challenges, and postoperative complications. Cholecystostomy-related complications were observed in seven patients. The conversion rate for was 25% for group A and 5% for group B. The incidence of intraoperative biliary injury was 10% for group A and 2.2% for group B. In group A, 92% of patients with biliary injury and 80% of those who required conversion to open surgery had evidence of localized inflammation around the gallbladder. Conclusion: For selected patients with grade II AC and higher risks, PC placement can be beneficial in preventing life-threatening consequences. The study suggests a 2-month interval between PC and subsequent LC. Overall, performing LC after PC was found to be easier than early LC. Local inflammatory changes, including empyema, were associated with higher complication rates in the early LC group.
