Complication Analysis with Percutaneous Postoperative Choledochoscopy in 826 Patients: A Single-Center Study.

Background

Advances in choledochoscopy technology lead to an improvement in the treatment of hepatolithiasis. The aim of this study is to analyze the complications and efficacy of percutaneous postoperative choledochoscopy (PPOC) for residual stones. Materials and

Methods

Retrospective analysis of patients who underwent PPOC for residual stones. Main outcome measures included the rate of stone removal and postoperative complications.

Results

Eight hundred twenty-six patients received PPOC. The average duration of choledochoscopy was 30 min (range, 14-42 min). Complications included basket incarceration, T-tube dislodgement, bleeding, bile leaks, and infection. Residual stone clearance rate was achieved in 97% of the cases.

Conclusions

PPOC is a safe and effective approach for residual stones.
