The Success Rate Is Lower but Completion Rate of Laparoscopic Cholecystectomy Is higher in Endoscopic Transpapillary Gallbladder Drainage than Percutaneous Gallbladder Drainage for Acute Cholecystitis

Background: We investigated the success and complication rates of endoscopic transpapillary gallbladder drainage (ETGBD) and percutaneous transhepatic gallbladder drainage (PTGBD) and the outcomes of subsequent cholecystectomy for acute cholecystitis. Methods: Patients (N=178) who underwent cholecystectomy after ETGBD or PTGBD were retrospectively assessed. Results: ETGBD was successful in 47 (85.5%) of 55 procedures, whereas PTGBD was successful in 123 (100%) of 123 sessions ( P <0.001). Complications related to ETGBD and PTGBD occurred in 6 (12.8%) of 47 and 16 (13.0%) of 123 patients, respectively ( P =0.97). After propensity matching, 43 patients from each group were selected. Median time from drainage to cholecystectomy was 48 (14 to 560) days with ETGBD and 35 (1 to 90) days with PTGBD ( P =0.004). Laparoscopy was selected more often in the ETGBD group (97.7%) than in the PTGBD group (79.1%) ( P =0.007), and conversion from laparoscopy to open cholecystectomy was more common with PTGBD (41.2%) than with ETGBD (7.1%) ( P <0.001). Mean operation time was significantly shorter with ETGBD (135.8±66.7 min) than with PTGBD (195.8±62.2 min) ( P <0.001). The incidence of Clavien-Dindo grade ≥III postoperative complications was 9.3% with ETGBD and 11.6% with PTGBD ( P =0.99). Conclusions: The success rate is lower but completion of laparoscopic cholecystectomy is more in endoscopic gallbladder drainage than percutaneous gallbladder drainage for acute cholecystitis.
