RESUMO
BACKGROUND: Gastrointestinal stromal tumors (GISTs) are low-grade malignant tumors that may arise anywhere in the alimentary tract, and in the past, most of them were diagnosed as intestinal leiomyoma or leiomyosarcoma. GISTs of the duodenum make up only 4.5% of all GISTs. MATERIALS AND METHODS: We report a patient presented with upper GI bleeding who exhibited radiological findings of a tumor in the third portion of the duodenum. The patient underwent a segmental duodenectomy. Pathological examination concluded in a GIST. RESULTS: The patient is free of recurrence for one year after surgery. CONCLUSIONS: Our case report, along with other, highlights that surgical resection remains the cornerstone of treatment for patients with localized disease. Along with others, we agree that from oncologic point of view, partial resection of the duodenum is an alternative to a duodenopancreatectomy.

By inducing experimental ulcers in the rabbit with the type 1 Herpes simplex strain, isolated from the herpes vesicles from a vagotomized patient, the authors demonstrate the protective role of vagotomy, the ulcerogenic capacity of the virus, which can be considered as an etiological factor of human gastroduodenal ulceration. They also discuss the possibilities for a new medical therapy of this disturbance.
