Vagotomy is a surgical procedure in which the vagus nerve is cut to reduce gastric acid production. It is rarely performed today due to modern drug therapies.
What is a Vagotomy?
A vagotomy is a surgical procedure in which the vagus nerve (cranial nerve X) is partially or completely severed. The vagus nerve plays a key role in regulating many bodily functions, including the stimulation of gastric acid secretion. By interrupting this nerve pathway, acid production in the stomach can be significantly reduced. Vagotomy was historically used as a primary treatment for peptic ulcers, including both gastric and duodenal ulcers.
Types of Vagotomy
Several types of vagotomy exist, each differing in scope and clinical impact:
- Truncal Vagotomy: Both main trunks of the vagus nerve are completely severed. While this effectively reduces acid secretion, it also affects other abdominal organs such as the intestines, liver, and gallbladder. A drainage procedure (e.g., pyloroplasty or gastroenterostomy) is typically required alongside this approach.
- Selective Vagotomy: Only the gastric branches of the vagus nerve are divided, sparing other organs. A drainage procedure is still usually necessary.
- Highly Selective Vagotomy (Proximal Gastric Vagotomy): Only the nerve fibers supplying the acid-producing parietal cells in the fundus and body of the stomach are cut. The antral innervation and gastric emptying remain intact, eliminating the need for an additional drainage procedure. This was long considered the preferred and most refined technique.
Indications
Vagotomy was primarily indicated for:
- Chronic or refractory gastric ulcers and duodenal ulcers
- Complications such as gastrointestinal bleeding or perforation
- Recurrent ulcer disease unresponsive to medical therapy
Relevance Today
The introduction of proton pump inhibitors (e.g., omeprazole) and the discovery of Helicobacter pylori as a major cause of peptic ulcers in the 1980s and 1990s dramatically reduced the need for vagotomy. Medical management is now the standard of care in the vast majority of cases. Surgical intervention, including vagotomy, is reserved for rare situations such as treatment failure, perforation, or uncontrolled bleeding.
Procedure
Vagotomy is performed under general anesthesia. Traditionally carried out as open surgery, it can in some cases be performed laparoscopically (minimally invasively). The surgeon identifies the relevant vagal trunks or branches and divides or resects the targeted nerve segments.
Risks and Side Effects
As with any surgical procedure, vagotomy carries certain risks and potential complications:
- Dysphagia (difficulty swallowing) due to injury to adjacent structures
- Diarrhea, particularly following truncal vagotomy, due to altered intestinal motility
- Delayed gastric emptying (gastroparesis) if an appropriate drainage procedure is not performed
- General surgical risks including infection, bleeding, and anesthesia-related complications
- Ulcer recurrence in a small percentage of patients
Follow-up Care
Regular follow-up examinations of the gastrointestinal tract are recommended after vagotomy. Patients should monitor for symptoms such as persistent upper abdominal pain, nausea, or changes in bowel habits and seek medical evaluation promptly if these occur. Dietary adjustments may help manage postoperative symptoms.
