Persistent exacerbation of a peptic ulcer may lead to complications (perforation and\/or bleeding). There has been a trend toward the use of a less invasive surgical simple suture, simple local suture or non\u2010operative (endoscopic\/angiography) hemostasis rather than acid\u2010reducing vagotomy (i.e., vagus nerve severance) for treating complicated peptic ulcers. Other studies have shown the relationship between high vagus nerve activity and survival in cancer patients via reduced levels of inflammation, indicating the essential role of the vagus nerve. We were interested in the role of the vagus nerve and attempted to assess the long\u2010term systemic effects after vagus nerve severance. Complicated peptic ulcer patients who underwent truncal vagotomy may represent an appropriate study population for investigating the association between vagus nerve severance and long\u2010term effects. Therefore, we assessed the risks of subsequent ischemic stroke using different treatment methods in complicated peptic ulcer patients who underwent simple suture\/hemostasis or truncal vagotomy\/pyloroplasty.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We selected 299,742 peptic ulcer patients without a history of stroke and Helicobacter pylori infection and an additional 299,742\u00a0matched controls without ulcer, stroke, and Helicobacter pylori infection from the National Health Insurance database. The controls were frequency matched for age, gender, Charlson comorbidity index (CCI) score, hypertension, hyperlipidemia history, and index year. Then, we measured the incidence of overall ischemic stroke in the two cohorts.

In complicated peptic ulcer patients, those who received truncal vagotomy and pyloroplasty had a lower risk of ischemic stroke than patients who received simple suture\/hemostasis (HR = 0.70, 95% CI = 0.60\u20130.81).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our findings suggest that patients with peptic ulcers have an elevated risk of subsequent ischemic stroke.
