Details and patient eligibility

About

The aim of the clinical trial is to investigate whether the use of a new multichannel endoscopic transanal access device (named UNI-VEC) is safe and effective in the resection of a rectal polyp or tumor that sits in the distal part of the colon (up to about 20 cm from the anal margin). This is the first study to test the device in humans, after proving its good performance in preclinical development (preclinical development has included functional laboratory tests and an animal trial).
