Materials and methodsA 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. ResultsA 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 35mm. 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. ConclusionsThe 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. ER -
