Efficacy and Safety of Endoscopic Removal for Asymptomatic Common Bile Duct Stones in Comparison with Symptomatic Stones.

OBJECTIVE

Endoscopic removal is recommended for common bile duct stones (CBDs). However, in patients with asymptomatic CBDs, follow-up without treatment may be recommended because of the increased complication risks associated with asymptomatic CBDs removal. The objective of our study was to investigate the efficacy and safety of CBDs removal in asymptomatic patients.

METHODS

Consecutive patients with naive papilla who underwent endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of CBDs from April 2016 to August 2020 were retrospectively analyzed. We compared the efficacy and safety of CBDs removal in asymptomatic and symptomatic patients.

RESULTS

We enrolled 300 patients, 53 asymptomatic and 247 symptomatic patients. Endoscopic CBDs removal was successful in all patients, except one symptomatic patient. However, the complete stone removal rate in a single session was significantly higher in the asymptomatic group than that in the symptomatic group. ERCP-related complications did not differ between the asymptomatic and symptomatic patients. The incidence of post-ERCP pancreatitis was similar and liver cirrhosis was the only significant risk factor for pancreatitis.

CONCLUSION

Complication risks associated with endoscopic CBDs removal was not significantly different between asymptomatic and symptomatic patients. Liver cirrhosis was a significant risk factor of ERCP-related pancreatitis.
