Vagotomy

Vagotomy is a surgical procedure that involves removing part of the vagus nerve, a nerve that transmits information from the brain to the stomach. This procedure is typically performed to treat peptic ulcers that are not responding to medication.

Procedure

Vagotomy is performed under general anesthesia. The surgeon makes an incision in the abdomen and locates the vagus nerve, which runs from the brain to the stomach. The nerve is then cut or removed. This reduces the amount of acid produced by the stomach, which can help to heal peptic ulcers and prevent them from recurring.

There are several types of vagotomy, including:

• Truncal vagotomy: This involves removing a large portion of the vagus nerve. It is often performed in conjunction with a procedure called a pyloroplasty, which widens the opening between the stomach and the small intestine to improve stomach emptying.

• Selective vagotomy: This involves removing only certain branches of the vagus nerve. It is less likely to cause complications than a truncal vagotomy, but it may not be as effective at treating peptic ulcers.

• Highly selective vagotomy: This involves removing only the part of the vagus nerve that controls acid production in the stomach. It is the least likely to cause complications, but it is also the least effective at treating peptic ulcers.

Risks and Complications

Like all surgeries, vagotomy carries some risks, including infection, bleeding, and reactions to anesthesia. Other potential complications specific to vagotomy include:

• Dumping syndrome: This is a condition in which food moves too quickly from the stomach into the small intestine. It can cause symptoms such as nausea, vomiting, and diarrhea.

• Gastric stasis: This is a condition in which the stomach empties too slowly. It can cause symptoms such as nausea, vomiting, and feeling full quickly.

• Recurrent ulcers: Although vagotomy can help to heal peptic ulcers and prevent them from recurring, some people may still develop ulcers after the procedure.

Recovery

Recovery from vagotomy typically takes several weeks. Patients may need to follow a special diet to help their stomach adjust to the changes. They may also need to take medication to control any symptoms or complications.
