To analyze factors involved in procedural failure and to discuss responses by using the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) carried out a short-type single-balloon enteroscope (short SBE) patients with surgically altered gastrointestinal anatomy.The study sample included who underwent ERCP-related procedures short SBE between September 2011 2018 at our hospital. Outcomes, including success rate, were studied retrospectively failure.Analysis 191 121 patients. Procedural rate was 85.9% an adverse event 8.4%. Causes malignant biliary obstruction (odds ratio [OR] 2.89, 95% confidence interval [CI] 1.19-7.25, P = 0.02), first ERCP attempt (OR: 5.32, CI: 1.30-36.30, Roux-en-Y reconstruction 0.08, 0.004-0.39, < 0.001). With regard response failure, cases obstruction, reattempted SBE-assisted difficult because invasion small intestine or papilla. A large number these required alternative treatment (10 15 cases, 66.7%) percutaneous transhepatic drainage (PTBD) ultrasound-guided (EUS-BD).Endoscopic is safe effective, being specific cause failure. Technical proficiency different modalities, such as PTBD EUS-BD, necessary respond cases.
