¹Studies which were designed to include cases where endoscopic mechanical lithotripsy was performed along with the first session of endoscopic papillary large balloon dilation;

²Calculated by dividing total number of procedures into total number of sessions which was calculated by multiplying each mean number of session with each number of procedures;

³Total number of procedures was 546 due to missing data;

⁴Total number of procedures was 617 due to missing data. EST: Endoscopic sphincterotomy; EML: Endoscopic mechanical lithotripsy; Prior: Prior endoscopic sphincterotomy; NA: Not available.
