Safe resection of gastrointestinal stromal tumor adjacent to the esophagogastric junction: Endoscopic transgastric wedge resection

Abstract

Introduction: Gastrointestinal (GI) tumors are submucosal lesions with malignant potential, most commonly found in the stomach. Materials and Methods: Between 2017 and 2023, patients with a pre-diagnosis of GI stromal tumors (GISTss) located adjacent to the gastroesophageal junction, exophytic growth into the stomach and masses below 5 cm were excised with endoscopic stapler placed transgastrically under endoscopic vision. The gender, age, length of hospitalization, post-operative complications, and pathology results of the patients were recorded retrospectively. Results: 58 patients with a pre-diagnosis of GIST were operated. 19 of them were located adjacent to the esophagogastric junction. 2 of 19 patients underwent total gastrectomy and 3 underwent proximal gastrectomy. 14 patients underwent transgastric resection and 2 of these patients were excluded from the study because the pathology result could not be GIST. No signifcant complications were observed in any of the 12 patients included in the study. Conclusion: Transgastric wedge resection under endoscopic visualization is a safe and organ-sparing surgical method for GISTs below 5 cm located adjacent to the esophagogastric junction.
