The aim of our study was to analyze the results of surgical management of gastrointestinal stromal tumors (GIST) at the Vichy Hospital Center. Methodology: Between 2010 and 2020, the data of 6 patients operated at the Vichy Hospital Center for GIST were analyzed. The parameters studied were: age, sex, antecedents, discovery circumstances, imagery, surgical procedure, anatomopathological data, the follow-up and the morbidity-mortality. Results: There were 5 men and one woman with an average age of 72.16 years [58 - 80 years]. The average time of evolution was 8 months (0 - 14 months). The diagnosis was fortuitous in 2 cases. Atypical abdominal pain was the main symptom in 3 cases. One case was received in a clinical picture of peritoneal irritation syndrome. Echo-endoscopy with biopsy specimen histology made it possible to make the diagnosis in 5 cases and the surgical specimen in 1 case. The fusiform type was the predominant histological form. The stomach was the most common location. The average size of GISTs was 7.3 × 4 cm with a positive C Kit in all patients. Neoadjuvant chemotherapy was performed on one patient. Surgery was curative and was done laparoscopically on 4 patients. Adjuvant chemotherapy based on Imatinib at a rate of 400 mg/d in 3 patients was initiated. One patient presented a fistula of the esophagus-jejunal anastomosis on D6 post operation controlled by a drainage and an antibiotic therapy. Mortality was zero. During the surgery, all of the patients were followed up with surgeon, oncologist. Conclusion: GISTs are the most common mesenchymal tumors of the digestive tract with a preferential gastric location. Laparoscopic surgery, with advances in molecular biology and the introduction of targeted therapy has improved the management of these tumors in terms of morbidity and mortality.
