Abstract

We report the case of a 71-year-old man with afferent loop obstruction (ALO) after Roux-en-Y reconstruction due to gastric cancer. Computed tomography showed a distended afferent loop and a dilatated bile duct. We could not reach the stricture site in the afferent loop using a gastroscope. We performed percutaneous transhepatic biliary drainage (PTBD) and placed a self-expanding metallic stent (SEMS) in the duodenal stricture through the PTBD route. Although an endoscopic approach is preferable, when PTBD can be performed, percutaneous transhepatic SEMS placement might be an alternative option for treating ALO in cases in which it is not possible to reach the site of stenosis with an endoscope.
