Medium term complications of endoscopic biliary sphincterotomy

Area of Science:

• Gastroenterology
• Endoscopic Procedures
• Biliary Tract Surgery

Background:

• Choledocholithiasis (common bile duct stones) is a frequent complication after cholecystectomy.
• Endoscopic biliary sphincterotomy (EBS) is a primary treatment for choledocholithiasis.
• Assessing the long-term outcomes and complications of EBS is crucial for patient management.

Purpose of the Study:

• To evaluate the medium-term outcomes and complications of endoscopic biliary sphincterotomy for choledocholithiasis.
• To assess patient symptoms, common bile duct stone clearance, and adverse events following EBS.

Main Methods:

• A retrospective review of 115 patients who underwent successful EBS for choledocholithiasis.
• Follow-up ranged from 18 months to 5 years, including interviews and postal questionnaires.
• Radiological assessment was used to evaluate common bile duct patency and sphincter function.

Main Results:

• Most patients (81%) had undergone prior cholecystectomy.
• Common bile duct stone clearance was documented in 76% and presumed in 17%.
• No serious new problems were reported; cholangitis and recurrent stones were rare. Bile duct gas was observed in 41% of patients, indicating sphincter incompetence.

Conclusions:

• Endoscopic biliary sphincterotomy demonstrates a low rate of medium-term complications for choledocholithiasis.
• Successful stone clearance and symptom resolution are common post-procedure.
• Sphincter incompetence is a potential finding but does not appear to lead to significant adverse events in the medium term.
