This study was a therapeutic research conducted as a retrospective study, aiming to compare the success of complete stone clearance during the second session of endoscopic retrograde cholangiopancreatography between patients with large common bile duct stones who underwent single plastic stent placement and those who received multiple plastic stent placements. The study population comprised 360 patients diagnosed with choledocholithiasis and treated at Hat Yai Hospital, including 180 patients in the Single Plastic Stent Placement group and 180 patients in the Multiple Plastic Stent Placement group. The research instruments consisted of a data collection form for demographic characteristics, health status, and treatment information, along with a record form for complete stone clearance outcomes. Data were analyzed using descriptive statistics, including frequency distribution and percentage calculation, as well as the independent t-test for inferential analysis.
The results indicated that there were no statistically significant differences (p > .05) between the Single and Multiple Plastic Stent Placement groups in baseline stone size prior to ERCP, mean complete stone removal, or residual stone size after each treatment session. However, a highly significant difference (p < .001) was found in the number of plastic stents used, with the Single group receiving only one stent, whereas the Multiple group required more than one stent.
