Treatment of posterior gastric wall gastrointestinal stromal tumor with gastric sleeve: a case report

Abstract

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial tumors of the gastrointestinal tract. The most usual location is the stomach, followed by the small intestine, where it may cause digestive bleeding and anemia. Surgical resection of the tumor is the gold standard treatment, and definitive diagnosis is based on immunohistochemical analysis of the surgical specimen. We report the case of a 53-year-old man with gastric GIST presenting with endophytic and exophytic growth, located at the posterior wall of the stomach, in the antrum-body transitional zone, treated with gastric sleeve.
