Usefulness of Endoscopic Retrograde Cholangiopancreatography (ERCP)-Related Procedures for Gallstone Pancreatitis.

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) are said to be useful procedures for gallstone pancreatitis. However, there have been few reports on a large number of patients to whom they were used. The clinical usefulness of ERCP and EST is herein examined retrospectively.

METHODS

ERCP and EST were performed to evaluate their clinical usefulness and safety in 108 patients who had gallbladder stones from December 1985 to October 2017 and were diagnosed as having gallstone pancreatitis. Of 108 patients, 83 were mild, and 25 were severe. Following the procedures, clinical courses were observed for three years in 108 patients who underwent the treatments.

RESULTS

Cholangiogram was successfully conducted in 108 patients. Bile duct stones were noted in 90 patients, and the stones were removed after EST. Of 18 patients who did not show bile duct stone in cholangiogram, 13 patients underwent EST, while five patients taking anticoagulants completed procedures only with cholangiogram. Accidental symptom was hemorrhage in three patients (2.7%; 3/108), but it was mild and conservatively resolving. During the three-year observation period, acute cholangitis was noted in three patients (2.7%; 3/108), but no relapsing pancreatitis was noted.

CONCLUSIONS

It was suggested that ERCP and EST could be useful therapies for gallstone pancreatitis.
