Efficacy and Factors Affecting Procedure Results of Short-Type Single-Balloon Enteroscopy–assisted ERCP for Altered Anatomy: a Multicenter Cohort in Japan
Gastrointestinal endoscopy(2022)
摘要
Background and Aims: Although single-balloon enteroscopy (SBE)-assisted or short-type SBE (short SBE)assisted ERCP has been reported as useful in patients with surgically altered anatomy, most studies had small sample sizes or single-center designs. This study aimed to evaluate the efficacy and factors affecting the procedure results of short SBE-assisted ERCP in patients with surgically altered anatomy. Methods: This multicenter, retrospective study was conducted at 8 tertiary referral care centers in Japan. The data of patients who underwent ERCP-related procedures using short SBE between September 2011 and August 2019 at each facility were analyzed. Results: Overall, 1318 patients were included in this analysis. The enteroscopy (reaching the target site), cannulation, and total procedural success rates were 87.9% (95% confidence interval [CI], 86.1%-89.6%), 87.0% (95% CI, 84.9%-88.8%), and 74.9% (95% CI, 72.5%-77.2%), respectively. Adverse events occurred in 7.7% of patients (95% CI, 6.4%-9.3%). Multiple logistic regression analysis indicated that age (>= 75 years), Roux-en-Y reconstruction, pancreatic indication, and malignancy were factors affecting the total procedural failure. Conclusions: This large-scale study proved that short SBE-assisted ERCP in patients with surgically altered anatomy was effective. Moreover, it clarified factors affecting procedure results. Proficiency with alternative treatment techniques is required in difficult cases.
