ENDOSCOPIC SUBMUCOSAL DISSECTION FOR THE TREATMENT OF A (GIANT) BALL VALVE SYNDROME

An 82 year-old female performed upper digestive endoscopy for diagnostic work-up of iron-deficiency anemia, which revealed a giant pedunculated gastric polyp obstructing the pylorus with extension to the second part of the duodenum. Biopsies were consistent with tubular adenoma with high-grade dysplasia. After multidisciplinary discussion, endoscopic submucosal dissection was performed and the lesion was successfully resected en-bloc without adverse events. Histopathological analysis of the specimen confirmed complete curative resection. This case highlights the expanding role of endoscopic submucosal dissection, which allowed a careful, controlled en-bloc resection of a giant gastric adenomatous polyp producing ball-valve syndrome.
