About

A feasibility study to assess the early safety and effectiveness of the Colovac 2 device in providing temporary protection of the anastomosis in patients undergoing low anterior resection for colon cancer.

Full description

A primary diverting stoma is widely used by surgeons to bypass the low rectal anastomosis and reduce morbidity associated with anastomotic leaks. Typically, a stoma is created for all high-risk patients which means that many patients are exposed to potentially serious complications associated with the stoma itself without any clinical benefit.

Colovac is a local, temporary, minimally invasive bypass device that protects the anastomosis and safely postpones stoma creation for 10 days after surgery. By postponing stoma creation for 10 days, Colovac allows stoma avoidance in all patients except those whose anastomosis have not healed by 10 days after surgery, allowing the others to return to normal activity more quickly and safely.

Eligible to undergo open or minimally invasive sphincter-sparing low anterior resection with planned diverting loop ileostomy for malignancy, based on multidisciplinary team recommendations
Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 2History of left sided colitis
Willingness to comply with protocol-specific treatment and study visits and to sign a written Informed Consent Form

Exclusion criteria

History of left sided colitis
Known allergy to nickel or other components of the Colovac 2 System
Pregnant or nursing female subject
Concomitant major surgical procedure in combination with Colorectal resection (i.e., hepatectomy)
Any serious or uncontrolled medical disorder that, in the opinion of the investigator, may increase the risk associated with study participation, impair the ability of the participant to undergo protocol described procedures or interfere with the interpretation of study results including, but not limited to:
Stage IV colorectal cancer unless curative intent R0 resection is planned AND there is no associated peritoneal disease
Immunodeficiency (CD4+ count < 500 CU MM)
Systemic steroid therapy within the past 6 months
Systemic infection at the time of surgery or requiring systemic antimicrobial therapy up to 1 week before surgery
Major surgical or interventional procedures within 30 days prior to this study or planned surgical or interventional procedures within 30 days of entry into this study
Diagnosis of bowel obstruction, bowel strangulation, peritonitis, bowel perforation, intraabdominal infection, ischemic bowel, carcinomatosis
Fecal incontinence, involvement of sphincter by the neoplastic disease or evidence of extensive local disease in the pelvis seen on pre-operative imaging
Severe malnutrition which is defined as at least 10% weight loss within 3 months prior to enrollment.
Occurrence of any of the following during the colorectal surgery:
1. Blood loss (>750 cc)
2. Blood transfusion
3. Any new sign of ischemia
4. Positive air leak test
5. Inadequate bowel preparation
6. Anastomosis location greater than 15 cm from the anal verge
7. Other intra-operative risks that preclude the subject from undergoing the procedure with the investigational device
