Disección sub-mucosa endoscópica en cáncer gástrico incipiente

Abstract

Endoscopic sub-mucosal dissection for early gastric cancer Introduction: Gastric cancer is the leading cause of mortality in Chile and the survival rates are in direct relation with the stage of the disease. Early gastric cancer is defined as that confined to the mucosa or submucosa, regardless of the presence or absence of regional lymph node metastases and it is characterized for its great prognosis, with a survival rate of more than 90% at ten years of follow up. Endoscopic submucosal dissection is a technique described and developed in Japan that allows the endoscopic complete en-bloc resection of lesions of more than 2 cm with tumor cell-negative margins. Method: Databases (Pubmed, EBSCO, Cochrane) were reviewed under the terms "gastric cancer", "early gastric cancer", "endoscopic submucosal dissection". Results: The results of published series demonstrate survival rates comparable to standard surgery with less morbidity and without mortality. The present revision describes the endoscopic submucosal dissection technique in early gastric cancer, its indications, the results, the analysis of the resected pieces, the complications and the follow up of the patients. Conclusion: Endoscopic submucosal dissection is a feasible technique, with excellent oncologic results and low morbidity in selected patients.

“…La técnica de DSE ha sido descrita ampliamente [21][22][23][24] . Básicamente se tiñe el tumor con índigo carmín y se marca todo su perímetro en mucosa sana unos 3 a 5 mm fuera de la lesión.…”
