New device may help colorectal cancer patients avoid a temporary colostomy

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients (18 years of age or older) * Eligible to undergo open or minimally invasive sphincter-sparing low anterior resection with planned diverting loop ileostomy for malignancy, based on multidisciplinary team recommendations. * Willingness to comply with Clinical Investigation Plan-specific treatment and study visits and to sign a written Informed Consent Form Exclusion Criteria: \- Preoperatively : 1. Patient with inflammatory bowel disease 2. Known allergy to nickel or other components of the Colovac+ kit 3. Pregnant or nursing female subject 4. Concomitant major surgical procedure in combination with Colorectal resection (i.e. hepatectomy) 5. 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 Clinical Investigation Plan described procedures or interfere with the interpretation of study results. including, but not limited to: 1. COVID-19 positive (active infection) based on test within 72 hours prior to surgery 2. Metastatic disease - unless previously treated with chemotherapy and resection, and the benefit of exposure to the Colovac device is greater than the risk 1 3. Immunodeficiency (CD4+ count \< 500 CU MM) 4. Systemic steroid therapy within the past 6 months 5. Systemic infection at the time of surgery or requiring systemic antimicrobial therapy up to 1 week before surgery 6. 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 7. Diagnosis of bowel obstruction, bowel strangulation, peritonitis, bowel perforation, intraabdominal infection, ischemic bowel, carcinomatosis 8. Fecal incontinence, involvement of sphincter by the neoplastic disease or evidence of extensive local disease in the pelvis seen on pre-operative imaging 9. Severe Malnutrition defined as 10% weight loss within 3 months prior to enrollment. 6. The subject is currently participating in another investigational drug or device study * Intraoperatively : 7. Anastomosis placement at more than 10cm from anal margin 8. 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 - requiring re intervention on the anastomosis 5. Inadequate bowel preparation 6. Other intra-operative risks that preclude the subject from undergoing the procedure with the investigational device
