Background And Aim:
This study aims to assess the clinical validity and safety of single-operator cholangioscopy system (SOCS) for the treatment of concomitant gallbladder stones and secondary common bile duct (CBD) stones.
Methods:
This retrospective study included 10 consecutive patients who had small-sized stones (< 1 cm) in both the gallbladder and CBD; the patients underwent SOCS treatment from June 2016 to December 2016. The clinical validity of this minimally invasive surgery was determined by the operation success rate, stone removal rate, postoperative hospital stay, hospitalization cost, and contrast images before and after the operation. The clinical safety was evaluated by perioperative complications and outcomes, gallbladder stone recurrence, and gallbladder contractility function.
Results:
Both the technique success rate and the stone removal rate when using SOCS was 100%. There were no serious complications that occurred during the operation; three patients developed acute cholecystitis, and four patients underwent hyperamylasemia after the surgery. The average postoperative hospital stay was 5.8 ± 1.32 days, and the average hospitalization cost was 7466 ± 566.1 dollars. In the follow-up period, which ranged from 3 to 8 months, there was no stone residuals or recurrences in the gallbladder and CBD, and no patient showed a recurrence of biliary colic. In addition, the gallbladder contractility function was proven to be normal within 3 to 6 months after the operation.
Conclusions:
SOCS could successfully manage concomitant gallbladder stones and secondary CBD stones and precisely protect normal biliary function.
