Brief Summary:
A randomized trial to assess the safety and efficacy of CG-100 for reducing stoma creation rate in subjects undergoing mesorectal excision.

Condition or disease Intervention/treatment Phase
Rectal Cancer Rectal Tumor Rectal/Anal Device: CG-100 intraluminal bypass device Procedure: Stoma Not Applicable

Detailed Description:

A primary diverting stoma is widely used by surgeons in order to bypass the low rectal anastomosis and reduce morbidity associated with anastomotic leaks. Today a stoma is created for all high-risk patients even though the expected anastomotic leak rate is less than 20%. This means that 80% of patients are exposed to potentially serious complications associated with the stoma itself without any clinical benefit.

CG-100, a removable, temporary intraluminal bypass device, developed by Colospan, is designed to address this need by safely postponing the creation of a protective stoma until 10 days after surgery only for patients who need it (i.e. have a defect in the anastomosis); thereby allowing patients with an intact anastomosis a quicker and safer return to normal activity.
