Abstract

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal neoplasms of the gastrointestinal tract. They can originate in any sector of the gastrointestinal tract and represent 0.1 to 3% of all gastrointestinal tumors. Their most frequent topography is gastric (60%). In reference to the surgical treatment of gastric GIST tumors, these depend on several factors to be taken into account; the extension of the lesion (tumor stage), the size of the lesion and the topography. The fundic location close to the esophageal-gastric junction increases the risks of generating an eventual narrowing. The surgical treatment of tumors in this topography is a therapeutic challenge because it implies a mixed technique; combining laparoscopic surgery with endoscopy. The aim of the following article is to present the combined laparoscopic and endoscopically guided treatment of an atypical gastric resection for a GIST tumor. The combination of laparoscopic surgery and endoscopy are complementary techniques that provide safety and can be a valid therapeutic option in selected cases, especially in those with tumor location close to the esophageal-gastric junction.
