Case Report: Intractable hiccups induced by gallbladder necrosis after laparoscopic distal D2 radical gastrectomy: two cases report.

Gallbladder necrosis after gastrectomy is very rare, and intractable hiccups caused by gallbladder necrosis is even more rare. Its clinical presentations and management strategies have not been described in available literature. This report firstly describes the clinical presentations, cause, management strategies, and treatment outcome of intractable hiccups immediately after gastrectomy. When intractable hiccups occurs after gastrectomy and abdominal computed tomography (CT) indicates gallbladder enlargement, gallbladder necrosis should be considered. After cholecystectomy or ultrasound-guided percutaneous gallbladder drainage, the patients were successfully treated.
