Inclusion criteria

Inclusion criteria: From January 2016 to February 2025, patients and endoscopic procedures for bile duct stones in surgical altered anatomy (SAA) treated with either EUS-T or BE-ERCP. Bile duct stone 12mm or more in diameter

Exclusion criteria

Exclusion criteria: In patients who underwent EUS-T sessions following failed BE-ERCP sessions, or BE-ERCP sessions following failed EUS-T sessions, each EUS-T and BE-ERCP both the failed and subsequent alternative sessions was analyzed and compared separately as an individual session series if there was no change in the size and number of target stones. Cases treated alternately with EUS-T and BE-ERCP repeatedly (e.g., first treatment with EUS-T, second with BE-ERCP, third with EUS-T), those treated using the rendezvous technique, those who underwent on going treatment, cases without adequate datasets were excluded.
