Clinical efficacy and safety of endoscopic ultrasound‐guided gallbladder drainage replacement of percutaneous drainage: A multicenter retrospective study

摘要

Objectives Percutaneous transhepatic gallbladder drainage ( PTGBD ) is widely used for patients with acute cholecystitis. There are little data on the efficacy and safety of endoscopic ultrasound‐guided gallbladder drainage ( EUS ‐ GBD ) replacement of PTGBD in patients who cannot undergo cholecystectomy. Methods This multicenter retrospective study in Japan reviewed records of patients who underwent EUS ‐ GBD to replace PTGBD between January 2010 and December 2017. Outcomes evaluated included technical success, defined as successful stent placement between the gastrointestinal lumen and the gallbladder; clinical success, defined as subsequent removal of the percutaneous catheter; adverse events; and stent patency. Results EUS ‐ GBD was performed in 21 patients (14 women, mean age 77.5 ± 8.0 years) to replace PTGBD that had been instituted for acute cholecystitis ( n = 19) or obstructive jaundice ( n = 2). Technical success was achieved in 19 (90.5%). The median period from PTGBD placement to EUS ‐ GBD was 11 days (range, 6–68 days). The mean procedure time was 19.5 ± 5.1 min. No early adverse events were observed. There were three late adverse events, distal stent migration in two cases and stent occlusion causing recurrent cholecystitis in one patient. Reintervention was required in two patients. The percutaneous catheter was removed after EUS ‐ GBD in 17 patients at a median of 7 days (range, 2–20 days). The duration of stent patency was 139 days (range, 8–664 days). Conclusions Where ongoing gallbladder drainage is required, conversion from PTGBD to EUS ‐ GBD is a feasible, effective, and safe technique for patients who cannot undergo cholecystectomy.
