Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) has become increasingly utilized to palliate malignant biliary obstruction in patients with inaccessible papillae as a result of duodenal tumor invasion [1] [2]. Although a covered self-expandable metal stent (SEMS) is preferred to a plastic stent in EUS-HGS because of its lower risk of bile leakage [3], SEMS migration can be a fatal complication [4]. Herein, we present a case in which a SEMS at risk of proximal migration was successfully managed by adding plastic stents to serve as an anchor.
An 82-year-old man, who had undergone transpapillary stenting using a covered SEMS for distal bile duct cancer, presented with duodenal obstruction. The biliary SEMS was removed endoscopically, followed by duodenal SEMS placement, and EUS-HGS was performed in segment 3 using a covered SEMS (modified-GIOBOR, width 10 mm, length 10 cm, 1-cm uncovered portion at the proximal end; TaeWoong Medical Inc., Gimpo, Korea). The following day, percutaneous transhepatic biliary drainage was performed for cholangitis in segment 2. During this procedure, there was proximal dislocation of the SEMS as a result of interference between the percutaneous transhepatic biliary drainage catheter and the SEMS. A therapeutic duodenoscope (JF-260V, Olympus, Tokyo, Japan) was inserted immediately, and the distal SEMS end was barely observed ([Fig. 1]). The SEMS was moved 2 cm into the stomach by grasping its distal end using biopsy forceps. Subsequently, we punctured the covered mesh wall of the SEMS using an endoscopic retrograde cholangiopancreatography (ERCP) cannula and a 0.035-inch guidewire ([Fig. 2]), and placed a 5-Fr plastic stent (Geenen, Cook Endoscopy, Winston-Salem, North Carolina, USA). Another plastic stent was placed similarly in a crisscross manner ([Fig. 3]). The patient did not develop any further complications, including cholangitis or SEMS migration.

The management of SEMS migration in EUS-HGS is technically demanding and potentially requires surgical intervention [5]. Crisscrossing anchor stents can be used as a salvage technique to prevent this complication.
