Dormia Basket versus Extraction Balloon in Proximally Migrated Biliary Stents

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Biliary Interventions

Background:

• Proximally migrated biliary plastic stents pose a retrieval challenge.
• Endoscopic interventions are crucial for managing migrated stents.
• Comparing retrieval methods is essential for optimizing patient outcomes.

Purpose of the Study:

• To compare the efficacy of balloon extraction versus Dormia basket for retrieving proximally migrated biliary plastic stents.
• To evaluate procedural time, success rates, and complication incidence between the two methods.

Main Methods:

• A prospective study involving 80 adult patients with proximally migrated biliary plastic stents.
• Patients were divided into two groups: Group A (Dormia basket) and Group B (balloon extraction).
• Efficacy, procedural time, and complications were analyzed using SPSS 21.

Main Results:

• Balloon extraction (Group B) demonstrated a significantly shorter mean procedure time (37.5 min) compared to Dormia basket (Group A) (57.4 min).
• Fewer patients required a change of method in the balloon extraction group (20%) versus the Dormia basket group (37.5%).
• Complication rates were similar between the two groups (5.0% for balloon extraction vs. 7.5% for Dormia basket).

Conclusions:

• Balloon extraction is a more successful and efficient method for retrieving proximally migrated biliary plastic stents.
• The findings suggest balloon extraction as a preferred endoscopic approach for this indication.
• Further research could explore long-term outcomes and patient-specific factors influencing retrieval success.
