[Vagotonía. The medical thesis of Salvador Zubirán]. / Vagotonía. La tesis recepcional de Salvador Zubirán.

Salvador Zubirán submitted his thesis for his MD degree in 1923. This thesis falls within the context of the new Mexican physiological medicine and denotes the visionary character of its author. Zubirán appears here as the introducer in Mexico of the physiopharmacological approach in autonomic nervous system disorders.

The history of vagotomy.

The anatomic characteristics of the vagus nerve were described by Galen in the second century AD, and its physiology was studied by Pavlov almost a century ago. Therapeutic possibilities of vagal denervation of the stomach was explored by several surgeons in the first quarter of this century. The most auspicious effort was that of Latarjet. The rebirth of vagotomy in 1943 by Dragstedt was based on cumulative new data supporting the concept that vagal denervation should favorably influence the clinical course of duodenal ulcer. This now proved concept renders vagotomy in some form a basic part of all operations for duodenal ulcer. The Dragstedt operation, vagotomy and pyloroplasty, is particularly useful in cases of acute bleeding and obstruction. Vagotomy and antrectomy has the lowest ulcer recurrence rate. Parietal cell vagotomy has the lowest mortality and morbidity rates and is the procedure of choice in patients with uncomplicated, intractable duodenal ulcer.

Lester R. Dragstedt and his role in the evolution of therapeutic vagotomy in the United States.

The date October 22, 1993, marks the centenary of the birth of Lester R. Dragstedt. He emerged from humble roots of Swedish immigrant parents to become one of the pre-eminent surgical innovators of the twentieth century. Early in his scientific career, Dragstedt was profoundly influenced by another Swede, A. J. Carlson, who was initially employed as a Lutheran minister in Dragstedt's hometown of Anaconda, Montana. Carlson left the ministry for graduate school and later became chairman of The Department of Physiology at the University of Chicago. When Dragstedt finished his schooling, Carlson convinced him to attend the University of Chicago. In addition to Carlson, Dragstedt's research was influenced by many prominent physiologists and surgeons, including Pavlov and Latarjet. Their work, along with his own investigations, helped him both to formulate his hypotheses on the regulation of gastric acid secretion and to formalize the operation of truncal vagotomy. In 1943, Dragstedt initiated the clinical use of this procedure in North America. Although he studied his patients carefully and documented his results meticulously, the operation initially met with considerable resistance from both his medical and surgical colleagues. Over time, many other surgeons accepted vagotomy as a viable procedure and further modified his technique. The unique ability of Dragstedt to transfer his research studies to the development and implementation of rational surgical therapy remains an enduring example for the surgical profession.

Complications of vagotomy and pyloroplasty.

Vagotomy and pyloroplasty are associated with technical complications, the most important being rupture of the esophagus, splenic injury, leak at the pyloroplasty, and intra-abdominal bleeding. This operation can also be associated with other complications including epigastric fullness, dysphagia, vomiting of food, bilious vomiting, dumping, and diarrhea. The historical background and specific complications of each procedure are discussed.

Acid secretion after gastric operations.

In the early 20th century, the commonest surgical treatment of peptic ulcer was gastroenterostomy. Crohn and Wilensky demonstrated that this operation did not achieve its aim of markedly reducing gastric acidity or of accelerating motility. These results were highly controversial, but led to Lewisohn visiting Haberer in Austria in 1922, and convincing Dr. A.A. Berg to abandon gastroenterostomy and use partial gastrectomy as the standard ulcer operation, with additional vagotomy in those patients with duodenal ulcer with high acidity. In 1929, a few patients were treated by vagotomy and gastrojejunostomy by Dr. Ralph Colp, with discouraging results. It was only in the 1940s that Mount Sinai surgeons adopted transthoracic or subdiaphragmatic vagotomy and gastroenterostomy (or later, pyloroplasty) as their standard, effective acid-lowering treatment of peptic ulcers.

Vagotomy.

Peptic ulcer disease was for years a common indication for surgery in Danish hospitals and considerable experience in partial gastrectomy was gained. In spite of an unquestionable mortality rate and a number of patients having postgastrectomy complaints, results were generally recognized as acceptable. Danish surgeons were for long reluctant to take up vagotomy and drainage as a primary ulcer operation, but when they did start a large number of procedures were performed. In fact, the use of this treatment culminated during two to three decades. However, on a basis of experiences from these years, Danish research contributed actively to the international evolution of the surgical vagotomy technique, the evaluation of clinical results and the studies of postoperative alterations in gastric physiology.

A relic or still relevant: the narrowing role for vagotomy in the treatment of peptic ulcer disease.

BACKGROUND: Given the rise of medical treatment for peptic ulcer disease (PUD), surgical treatment is necessary only in select cases and emergencies. The authors assess the current relevance of surgical vagotomy to treat PUD and its complications. DATA SOURCES: Although historically significant, selective and highly selective vagotomy is very technically challenging, and highly selective vagotomy has a relatively narrow indication and high recurrence rates. Vagotomy and gastrectomy is associated with significant side effects. Two types of vagotomy remain relevant, within a narrow scope. Truncal vagotomy and pyloroplasty is safe and efficacious through a laparoscopic approach in certain emergent cases. Vagotomy and Roux-en-Y gastrojejunostomy can be used to treat severe PUD refractory to medical management. CONCLUSIONS: The role of vagotomy in the management of PUD has a rich history but predated pharmacologic control of acid and understanding of the role of Helicobacter pylori in the disease. Thus, the current role of vagotomy is significantly limited. Specifically, the emergent use of truncal vagotomy is warranted for patients who are either resistant or allergic to proton pump inhibitors.
