NCT ID NCT06152276

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study involved 132 adults with colorectal cancer who had standard surgery (low anterior resection) and a temporary ileostomy (a stoma to divert waste). The goal was to measure major complications after surgery and create a single safety endpoint. This will help doctors compare standard care to newer treatments in the future.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could establish a clear safety benchmark for comparing standard surgery to newer treatments for colorectal cancer.
What could go wrong
This is an observational study that does not test a new treatment, so it won't directly improve patient outcomes. Results may not change current practice.

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

Inclusion Criteria: 1. Adult patients (18 years of age or older) 2. Eligible to undergo open or minimally invasive sphincter-sparing low anterior resection with planned diverting loop ileostomy for malignancy, based on multidisciplinary team recommendations. 3. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 2 4. Willingness to comply with protocol-specific treatment and study visits and to sign a written Informed Consent Form Exclusion Criteria: Preoperative 1. History of left colitis 2. Known allergy to nickel or other components of the Colovac System (not applicable for control cohort) 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 protocol described procedures or interfere with the interpretation of study results including, but not limited to: 1. Stage IV colorectal cancer unless curative intent R0 resection is planned AND there is no associated peritoneal disease 2. Immunodeficiency (CD4+ count \< 500 CU MM) 3. Systemic steroid therapy within the past 6 months 4. Systemic infection at the time of surgery or requiring systemic antimicrobial therapy up to 1 week before surgery 5. 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 6. Diagnosis of bowel obstruction, bowel strangulation, peritonitis, bowel perforation, intraabdominal infection, ischemic bowel, or carcinomatosis 7. Fecal incontinence, involvement of sphincter by the neoplastic disease or evidence of extensive local disease in the pelvis seen on pre-operative imaging 8. 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. Occurrence of any of the following during the colorectal surgery: 1. Blood loss (\>750 cc) 2. Blood transfusion 3. Any new sign of bowel ischemia 4. Positive air leak test 5. Inadequate bowel preparation 6. Anastomosis location greater than 10 cm from the anal verge 7. Any other surgical complications or intra-operative risks that may place the patient at greater risk from study procedures
