Study summary

Megachannel is a newly developed colonic access system allowing rapid and multiple passes of the colonoscope to the right colon.

The investigators want to conduct a multinational study to evaluate the safety and clinical feasibility of placing a 100 cm Megachannel prototype in the right colon.

Read the detailed description

Patients scheduled for colonoscopy with suspected right colonic polypoid lesions will be included. The prototype will loaded onto a 160 cm lower GI endoscope and introduced via colonoscopic guidance. Time to cecum, total investigation time, clinical feasibility and complications will be recorded.
