Why does hiccups occur after surgery for hepatobiliary stones?

Hiccups after surgery for hepatobiliary duct stones may be caused by gastrointestinal gas release, surgical stimulation, or the effects of anesthetics. The details are as follows:

1. Gastrointestinal Gas Release

After surgery, patients need to rest in bed for a prolonged period, which may lead to the accumulation of large amounts of gas in the gastrointestinal tract, requiring release through hiccups.

2. Surgical Stimulation

During the operation, surgeons perform procedures on the patient's abdomen. This stimulation may affect the phrenic nerve, causing contractions of respiratory muscles and resulting in hiccups.

3. Effects of Anesthetics

Anesthetics used during surgery may impact the respiratory center and gastrointestinal motility, thereby triggering hiccups.

In addition, intra-abdominal fluid accumulation could also be a possible cause. If symptoms are severe or persist for a long time, it is recommended to consult a doctor for further evaluation and treatment.
