Hiccup is usually a self-limiting condition, and can be treated with medications and physical maneuvers. However, hiccup episodes continuing for days or weeks can be incapacitating, and disturb work, sleep, and eating. Therefore, timely therapeutic intervention is needed to achieve early resolution of this treatable condition. We report on a successful phrenic nerve block for intractable hiccups, which consisted of thoracoscopic nerve clipping under general anesthesia and reversal under local anesthesia. This method has the advantage of assured diaphragmatic functional recovery while controlling intractable hiccups.
