title: [Open submucosal dissection: first case described].
abstract: Endoscopic submucosal dissection is a new treatment, basically for the management of early gastric cancer, it is also a good option for large benign lesions if a "una pieza" resection needs to be performed. However this technique requires not only gastroenterologist with proven technical skill, but also some special devices not necessarily disposables in our country. The present paper describes the case of a patient with a large hyperplastic polyp located in the upper third of the stomach who underwent an open endoscopic submucosal dissection to resect the lesion owing to its size and characteristics. According our knowledge this is the first case in the medical literature describing the use of this technique during an open surgery.
