Abstract

Aim: to evaluate the early results of endoscopic submucosal tunnel dissection (ESTD for large benign colon neo-plasms. Patients and methods: a prospective non-randomized comparative study included 100 patients with large benignepithelial colon neoplasms (more than 3 cm in diameter). The main group included 50 patients who underwentendoscopic submucosal tunnel dissection. The control group included 50 patients who underwent traditional endo-scopic submucosal dissection (ESD). Results: Four (4 %) patients (1 in the main and 3 in the control group) were excluded from the study due to theconversion of endoscopic procedure. The incidence en bloc removal of neoplasms and the negative resection margins were significantly higher in the main group than in the control one — 98 % and 87.2 % (p = 0.04) and 89.8 % and 70.2 %, respectively (p = 0.01). Conclusion: ESTD for large benign epithelial colon neoplasms shows better radicalness in comparison with endo-scopic submucosal dissection.
