Introduction and aims: The aim of the present study was to evaluate the feasibility of endoscopic submucosal dissection (ESD) and determine the clinical and pathologic characteristics of early gastric cancers and premalignant lesions treated with that technique at the Hospital Nacional of the Department of Health and a private clinic in Lima, Peru. Materials and methods: A descriptive study of all pre-malignant and malignant gastric lesions treated with ESD at the Gastroenterology Service of the Hospital Arzobispo Loayza and the Clínica Angloamericana was conducted within the time frame of January 2012 and January 2017. Results: A total of 13 lesions were resected through ESD: 8 adenocarcinomas (61.53%), 3 adeno-mas with high-grade dysplasia (23%), and 2 adenomas with low-grade dysplasia (15.38%). Twelve lesions (92.3%) were located in the lower third of the stomach. Slightly elevated lesions (Paris classification IIa) (4 lesions, 30.76%) and mixed slightly elevated lesions with a depressed component (IIa + IIc) (4 lesions, 30.76%) predominated. The mean size of the resected specimens was 35 mm. Complete resection of all lesions was achieved in 11 cases (84.6%) and en bloc resection was carried out in 11 cases (84.6%). Resection was curative in 6 cases (75%), from the total of 8 resected adenocarcinomas. One case of perforation was the only complication reported (7.6%) and it was surgically resolved. Conclusions: The feasibility and efficacy of ESD for the treatment of early gastric cancer was demonstrated at two healthcare centers in Lima, Peru. The complication rate was similar to that reported in the international medical literature. Resumen: Introducción y objetivos: El objetivo del estudio fue evaluar la factibilidad de la disección endoscópica submucosa (DES) y determinar las características clínico-patológicas de los cánceres gástricos tempranos y lesiones premalignas tratados con esta técnica en un Hospital Nacional del Ministerio de Salud y en una clínica particular en Lima, Perú. Materiales y métodos: Estudio descriptivo de todas las lesiones gástricas malignas y premalignas tratadas con DES en el Servicio de Gastroenterología del Hospital Arzobispo Loayza y la Clínica Angloamericana desde enero de 2012 a enero de 2017. Resultados: Se resecaron un total de 13 lesiones con DES: 8 adenocarcinomas (61.53%), 3 adenomas con displasia de alto grado (23%) y 2 adenomas con displasia de bajo grado (15.38%). Doce lesiones (92.3%) se localizaron en el tercio inferior gástrico. Predominaron las lesiones plano elevadas (IIa de París; 4 lesiones, 30.76%) y las mixtas plano elevadas con componente deprimido (IIa + IIc; 4 lesiones, 30.76%). La media de tamaño del espécimen resecado fue de 35 mm. Se consiguió resección completa, del total de lesiones, en 11 casos (84.6%), y resección en bloque en 11 casos (84.6%). En 6 casos (75%), de un total de 8 adenocarcinomas resecados, se observó una resección curativa. Se reportó una complicación (7.6%) la cual fue perforación y se resolvió por cirugía. Conclusiones: En 2 centros de Lima, Perú, se demostró la factibilidad y eficacia de la DES para el tratamiento del cáncer gástrico precoz, con una tasa de complicaciones similar a la descrita en la literatura internacional.
