RESUMEN
Gastrointestinal mesenchymal tumors are classified as tumors that originate from smooth muscles. Gastrointestinal stromal tumors [GIST] are the most common types of the proposed tumors and can be seen in the GI tract from the esophagus to the anus, but they are mostly seen in the stomach. Mostly from the stomach and asymptomatic, the majority of patients would benefit from surgery as the best method of treatment. In this retrospective study we evaluated the data of patients with the diagnosis of esophageal or gastric mesenchymal tumors admitted in Ghaem and Omid Hospitals affiliated to Mashhad University of Medical Sciences in Iran, from 1992 to 2010. We analyzed factors such as age, sex, presenting symptoms and signs, diagnostic methods, types of pathology, types of treatment, morbidity, mortality and 3-year survival rates. Twenty four patients [16 male, 8 female] with a mean age of 50 were included in the study. The common site of tumor was gastric fundus. The most common symptom at the time of diagnosis was epigastric fullness which was observed in almost 50% of the patients. The most common type of surgery in the patients was subtotal gastrectomy and no hospital mortality was recorded. Paralytic ileus was the commonest complication seen in five patients [20.5%]. Adjuvant therapy had been performed in eight patients [33.1%]. Following the patients three years postoperatively, there were only three deaths [12.45%]. Regarding to the low mortality and morbidity of the surgeries, surgical treatment, if tolerated, is recommended for all Esophagogastric mesenchymal tumors patients
