EUS-guided hepaticogastrostomy (EUS-HGS) is sometimes performed as re-intervention in patients who have transpapillary biliary stent dysfunction associated with conditions such as gastric outlet obstruction. We describe a 92-year-old man in whom a covered self-expanding metal stent (SEMS) had been placed because of distal biliary obstruction caused by unresectable duodenal papilla cancer. The tumor invaded the distal portion of the duodenum, causing food retention and recurrent cholangitis due to duodenobiliary reflux. Although stent-in-stent placement of a plastic stent was performed, stent dysfunction soon occurred, requiring frequent replacement of the stent [Figure 1]. The SEMS was difficult to remove because of tumor ingrowth. We, therefore, designed a new method for large-balloon occlusion and successfully performed EUS-HGS [Video 1 and [Figure 2]]. After EUS-HGS, cholangitis did not occur until the patient died of duodenal papilla cancer. We previously designed and reported the large-balloon occupation technique designed for patients with many bile-duct stones that are difficult to remove. The new technique is based on this procedure. A balloon catheter is inserted into the bile duct upstream to the site of malignant biliary obstruction to induce occlusion. Contrast media and physiological saline solution are then injected into the bile duct to artificially dilate the intrahepatic portion of the bile duct [Figure 3] and perform EUS-HGS [Figure 2]. If the SEMS can be removed, endoscopic nasobiliary drainage is temporarily performed. However, endoscopic nasobiliary drainage is not feasible if the SEMS has been placed in the extrahepatic bile duct, similar to our patient. Adjustment of the expansion site of the balloon can prevent the injection of unnecessary contrast media into the gallbladder. This new technique is a useful procedure for performing EUS-HGS in patients who have undergone the placement of a SEMS for the distal malignant biliary obstruction that is difficult to remove.

A pancreatic plastic stent had been inserted to prevent pancreatitis. Cholangiography showed that contrast media flowed into the duodenum. The SEMS was patent.

A hyperechoic lesion suggestive of biliary sludge was found in the bile duct. Right: About 60 ml of physiological saline solution was injected, dilating the diameter of B3 to 5 mm|
