Background and Aims:The Endoscopic Retrograde Cholangiopancreatography (ERCP) is currently used for therapeutic purposes. In experienced hands the success rate is over 95%. The failure of ERCP to drain the bile duct in patients with biliary obstruction varies between 6% and 7%. In order to remedy failures, alternative techniques have emerged, such as Percutaneous Transhepatic Biliary Drainage (PTBD) and Endosonography-guided Biliary Drainage (EUS-BD). The objective of this systematic review was to assess which of the two techniques would be the best choice after ERCP failure.
Materials and Methods: We searched the databases, such as MEDLINE, Embase and Cochrane Central Library. Literature articles comparing EUS-BD vs. PTBD were included: randomized, prospective, non-randomized and retrospective trials.
Results:Fourteen articles were selected among them: randomized clinical trials (3), retrospective (10) and non-randomized prospective (1). Overall, we obtained 1,281 patients: 759 allocated to the EUS-BD group (intervention) and 522 to the PTBD group (comparison). Technical and clinical success was not statistically significant. And in relation to the number of adverse events, it had better statistical significance in the cases of RCTs. In technical success the risk difference IC 95%: 0.03 (-0.05, 0.11) with p>0.05 with heterogeneity of 26%, in clinical success the risk difference IC 95%: 0.00 (-0.12, 0.13) with p>0.05 with 0% heterogeneity. And in adverse events the risk difference IC 95%: -0.23 (-0.36, -0.09) with p<0.05 with 0% heterogeneity.
Conclusion:Technical success and clinical success did not have statistical significance, but with adverse events, the technique through endosonography had a decrease with adverse events.
