[Treatment with endoscopic endoprosthesis in choledocholithiasis]

Area of Science:

• Gastroenterology
• Endoscopic procedures
• Biliary tract interventions

Background:

• Choledocholithiasis, the presence of gallstones in the common bile duct, poses significant clinical challenges.
• Endoscopic retrograde cholangiopancreatography (ERCP) with endoprosthesis placement is a key intervention for managing choledocholithiasis.
• Assessing the long-term efficacy and safety of endoscopic endoprosthesis is crucial for patient management.

Purpose of the Study:

• To review the outcomes of endoscopic endoprosthesis placement in patients with choledocholithiasis.
• To evaluate the effectiveness of endoprosthesis as both a provisional and permanent treatment modality.
• To analyze complications and recurrence rates associated with endoscopic endoprosthesis.

Main Methods:

• Retrospective review of 51 patients undergoing endoscopic endoprosthesis placement for choledocholithiasis between October 1991 and December 1995.
• Categorization of endoprosthesis placement into provisional (13 cases) and permanent (38 cases).
• Follow-up assessment of clinical outcomes, including complications, recurrent obstructions, and need for further interventions.

Main Results:

• Endoscopic endoprosthesis was used provisionally in 13 cases and permanently in 38 patients.
• Three patients required prosthesis extraction; six experienced recurrent biliary obstruction, necessitating surgery or re-intervention.
• Only three mild episodes of cholangitis were observed as complications; most patients remained asymptomatic.

Conclusions:

• Endoscopic endoprosthesis is an effective provisional treatment for acute choledocholithiasis.
• It offers a permanent alternative for patients with unextracted stones post-sphincterotomy who are ineligible for other procedures.
• This technique is particularly valuable for patients with a limited life expectancy.
