Objective: We report a case of spontaneous migration of a dedicated plastic stent after endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) in a patient with surgically altered anatomy.Patient: The patient was a male in his 70s. He underwent EUS-HGS with the successful insertion of a dedicated plastic stent and had no obvious postprocedural complications. However, nine days after the procedure, the patient visited our hospital because of abdominal pain, fever, and stent excretion. We performed EUS-HGS with antegrade stenting, after which the patient had no further complications.Conclusion: Stent migration is considered a complication requiring caution when performing EUS-HGS in patients with surgically altered anatomy.
