Introduction: Endoscopic submucosal dissection Hybrid Knife (ESD-HK) is a promising technique for resection of early stage tumors. Few data in Latin America. Patients and methods: Prospective, descriptive study (March 2011-2012). 25 patients (16 men, 9 women), mean age 62.52 years (52-72 years).25 procedures were performed. Indications: sub-epithelial tumors (7), colorectal neoplasia (16) early gastric neoplasia (2) Results: ESD-HK was technically possible in all (25) lesions (100%). En bloc resection and free margins were obtained in all cases. The diameter of dissected mucosa was between 2-7 cms(X=3.8 cms) The time was between 45-120 minutes(X= 84.4 minutes). Perforation occurred in 2 cases being resolved with endoscopic treatment (clips). Mortality was not reported. Conclusions: Our preliminary results suggest that the DSE with Hibrid Knife (DSEH) seems to be a good option for endoscopic treatment of early stage gastric tumors, colon and rectal carcinoid tumors. Studies controlled, randomized DSE with Hibrid Knife, compared with other devices are needed.
