Background/Purpose Endoscopic transpapillary gallbladder drainage (ETGBD), including endoscopic nasogallbladder drainage (ENGBD) and endoscopic gallbladder stenting (EGBS), has been reported to be an effective treatment for acute cholecystitis. However, ETGBD is considered to be more difficult than percutaneous transhepatic gallbladder drainage (PTGBD), and few studies have evaluated the factors that affect technical success of the procedure. We investigated the factors predicting its technical success from among patient characteristics and image findings before treatment. Methods Three hundred twenty three patients who underwent ETGBD for acute cholecystitis from November 2006 to December 2018 were analyzed retrospectively. Results The technical success rate was 72.8% (235/323). The technical success rate by cystic duct direction was as follows: proximal/distal, 65.9%/93.6%; right/left: 74.0%/65.2%; cranial/caudal, 83.5%/20.0%. The clinical response rate was 96.2% (226/235). Adverse events were encountered in 5.9% of cases (19/323), including cystic duct injury (11 patients), pancreatitis (five patients), and bleeding (three patients). In both univariate and multivariate analysis, presence of cystic duct stone, dilation of the common bile duct (CBD), and cystic duct direction (proximal and caudal branches) were identified as significant factors affecting technical failure of ETGBD. Conclusion Although ETGBD was an effective and safe procedure for acute cholecystitis, it has a limited success rate. The presence of cystic duct stone, dilation of CBD, and cystic duct direction (proximal and caudal branches) can serve as important predictors of ETGBD difficulties. These findings should be considered before procedures and the necessary adaptation of ETGBD made.
