Potential Factors Affecting Results of Short-Type Double-Balloon Endoscope-Assisted Endoscopic Retrograde Cholangiopancreatography

Research output: Contribution to journalArticle

Abstract

Background: Short-type double-balloon endoscope (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) has been developed as an alternative approach for cases with a surgically altered gastrointestinal anatomy. However, this technique is sometimes technically challenging and carries a risk of severe adverse events. Aims: To evaluate the factors affecting the technical success rate and adverse events of DBE-ERCP. Methods: A total of 319 patients (805 procedures) with a surgically altered gastrointestinal anatomy underwent short DBE-ERCP. The factors affecting the technical success rate and adverse events, and the learning curve of the trainees were retrospectively evaluated. Results: The technical success rate of all procedures was 90.7%. Adverse events occurred in 44 (5.5%) procedures. A multivariate analysis indicated that Roux-en-Y reconstruction and first-time short DBE-ERCP were factors affecting the technical failure and adverse event rates, while the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction was a non-risk factor for adverse events. The trainee caseload did not affect the technical success or adverse event rates significantly; however, trainees tended to perform cases involving the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction. The success rate of scope insertion increased according to experience; however, the overall success rate did not differ to a statistically significant extent. Conclusion: Short DBE-ERCP was useful and safe for managing cases with a surgically altered anatomy; however, trainees should concentrate on accumulating experience with easy cases, such as those with the modified Child method after subtotal stomach-preserving pancreaticoduodenectomy reconstruction or a history of DBE-ERCP.
