Percutaneous transhepatic gallbladder drainage versus endoscopic gallbladder stenting for managing acute cholecystitis until laparoscopic cholecystectomy.

Introduction: Gallbladder drainage by methods such as percutaneous transhepatic gallbladder drainage (PTGBD) or endoscopic gallbladder stenting (EGBS) is important in the early management of moderate to severe acute cholecystitis.

Methods: In patients undergoing laparoscopic cholecystectomy (LC) for acute cholecystitis after a month or more of gallbladder drainage, the clinical course was compared between patients initially treated with PTGBD or EGBS.

Results: Among 331 patients undergoing LC for cholecystitis between 2018 and 2022, 43 first underwent 1 or more months of gallbladder drainage. The median interval between drainage initiation and LC was 89 days (range, 28-261) among 34 patients with PTGBD and 70 days (range, 62-188) among nine with EGBS (p = 0.644). During this waiting period, PTGBD was clamped in six patients and removed in five. Cholecystitis relapsed in three PTGBD patients (9%) and four EGBS patients (44%; p = 0.026). Relapses were managed with medications. Cholecystectomy duration (p = 0.022), intraoperative blood loss (p = 0.026), frequency of abdominal drain insertion (p = 0.023), and resort to bailout surgery such as fundus-first approaches (p = 0.030) were significantly greater in patients with EGBS. Postoperative complications were somewhat likelier (p = 0.095) and postoperative hospital stays were longer (p = 0.007) in the EGBS group.

Conclusion: Among patients whose LC was performed 1 or more months after initiation of drainage, daily living during the waiting period associated with drainage was well supported by EGBS, but LC and the postoperative course were more complicated than in PTGBD patients.
