Gastric and Peptic Ulcer Surgery

Gastric and peptic ulcer surgery is the operative management of peptic ulcer disease and its complications. Once a high-volume elective field built around acid-reducing operations such as vagotomy and gastric resection, it has contracted sharply since peptic ulceration was shown to be driven largely by Helicobacter pylori and by non-steroidal anti-inflammatory drugs, both of which are now addressed medically. Surgery today is dominated by the emergency treatment of complications — perforation, bleeding, and obstruction.

Definition

Gastric and peptic ulcer surgery comprises operations performed for peptic ulcer disease and its complications, including repair of perforation, control of bleeding, treatment of gastric outlet obstruction, and the historically common acid-reducing procedures such as vagotomy with or without gastric resection.

Scope

This entry describes the historical and contemporary role of surgery in peptic ulcer disease, the principal complications that bring patients to operation, the classic acid-reducing procedures of the pre-Helicobacter era, and the repair techniques used for perforation. It treats the topic as a reference subject within gastrointestinal surgery and does not give operative instructions or individualized treatment advice.

Core questions

• Why did elective surgery for uncomplicated peptic ulcer become rare?
• Which ulcer complications still require operation, and how are they categorized?
• What were the classic acid-reducing operations and what trade-offs did they carry?
• How is perforated peptic ulcer managed surgically in principle?

Key concepts

• Peptic ulcer disease
• Helicobacter pylori
• Perforation
• Upper gastrointestinal bleeding
• Gastric outlet obstruction
• Vagotomy
• Omental (Graham) patch repair
• Partial gastrectomy

Mechanisms

Peptic ulceration results from an imbalance between mucosal defence and acid-peptic aggression, most often in the setting of Helicobacter pylori infection or NSAID use; the recognition of the bacterial cause (Marshall & Warren, 1984) explained why eradication and acid suppression could heal ulcers that had previously been treated by surgically reducing acid secretion. The historical operations acted on this physiology — vagotomy interrupting vagal acid stimulation and gastric resection removing acid-secreting mucosa — at the cost of altered gastric emptying and nutritional sequelae. When an ulcer erodes through the wall it perforates, releasing gastric contents and causing peritonitis; surgical principles centre on controlling contamination and closing or patching the defect, commonly with an omental (Graham) patch, alongside treatment of the underlying cause (Soreide et al., 2015). Standardized grading of the resulting complications follows the Clavien-Dindo framework (Clavien et al., 2009).

Clinical relevance

Understanding when peptic ulcer disease crosses from a medically managed condition to a surgical emergency is central to acute general surgery, and the topic illustrates how a shift in disease understanding can transform a surgical field. This entry is educational and descriptive; it is not a guide to diagnosis or treatment, which require qualified clinical assessment.

Epidemiology

The incidence of elective peptic ulcer surgery has fallen dramatically over recent decades following H. pylori eradication and proton-pump-inhibitor therapy, while emergency presentations with perforation or bleeding remain clinically important and carry substantial mortality, particularly in older patients and those presenting late (Soreide et al., 2015).

History

For much of the twentieth century, elective surgery — vagotomy, pyloroplasty, and various gastric resections — was a mainstay of treatment for intractable peptic ulcer, and Lester Dragstedt's work on vagotomy shaped that era. The 1984 demonstration by Marshall and Warren that a curved bacterium colonizes the stomach in gastritis and peptic ulceration, later confirmed as Helicobacter pylori, overturned the acid-centred surgical paradigm; combined with effective acid-suppressing drugs, it left surgery largely to the management of complications, chiefly perforation and bleeding.

Debates

Open versus laparoscopic repair of perforated peptic ulcer

Laparoscopic repair of perforation can reduce wound complications and pain in selected stable patients, but its advantage over open repair in the sickest patients and its effect on leak and mortality remain debated.

Frequently asked questions

Why is surgery rarely used now for uncomplicated peptic ulcers?

Most peptic ulcers are caused by Helicobacter pylori infection or NSAID use and heal with eradication and acid-suppressing drugs, so the acid-reducing operations once used electively are now seldom needed.

When is surgery still needed for peptic ulcer disease?

Surgery is mainly reserved for complications such as perforation, bleeding that cannot be controlled endoscopically, and gastric outlet obstruction.
