... Pubmed, and Ovid and extracted data into an abstraction form. Meta-analysis for success rates was analyzed by calculating pooled proportion with inverse variance. A total of 172 SE-ERCPs were included in this analysis from five relevant studies. The pooled success rate of reaching the ampulla by spiral enteroscopy was 75%. SE-ERCP is a viable technique for diagnostic and therapeutic intervention of biliary disorders.
