"Dovetail" gastric resection: a novel model in the treatment of gastrointestinal stromal tumors

Gastrointestinal stromal tumors (GISTs) are the most common malignant subepithelial lesions of the gastrointestinal tract. The prognosis of this disease is associated with the tumor size and mitotic index. The standard treatment of a GIST without metastasis is surgical resection. The stomach is the most frequent site of the disease and many technical solutions have recently been proposed as shown also by the dramatic increase in publications on this field. There are many studies that suggest laparoscopy may be an acceptable surgical treatment option compared to open surgery for gastric GIST. However, open surgery assumes great importance in large tumors located in difficult to access locations. Here, we present a case involving a 60-year-old man who was diagnosed with gastric antrum GIST, according to a preoperative examination and postoperative pathology. Then, the patient successfully underwent an atypical gastric resection. We proposed a novel surgical technique to be considered in case of gastric benign disease or GIST localized at the gastric antrum
