Comparison between transpapillary versus transmural endoscopic ultrasound-guided decompression for biliary obstruction: a meta-analysis

Recent advances have led to the development of transmural endoscopic ultrasound guided biliary drainage (EUS-BD) for cases where the duodenal papilla cannot be accessed. We performed a meta-analysis comparing efficacy and complications of both approaches for biliary drainage. English articles were searched in PubMed. Primary outcomes included technical success and complications. Secondary outcomes were clinical success and subsequent stent malfunction. Patient demographics and etiology of obstruction were collected and relative risk ratios and 95% CIs were calculated. P-value
