Not Applicable

Conditions
Colorectal Neoplasms
Interventions
Device: C-REX
Registration Number
NCT06481605
Lead Sponsor
Istituto Clinico Humanitas
Brief Summary

The C-REX device is design to help colorectal anastomoses construction and reduce the risk of anastomotic leak. This study aims to collect preliminary evidence on the effectiveness of C-REX a real-word setting.

Detailed Description

Despite technological advancements, the rate of anastomotic leak after left colon and rectal resection remains high. In most cases, these complications are identified only from the clinical symptoms and the delay in the diagnosis may lead to more severe outcomes. The device C-REX, developed by CarpoNovum, may help the anastomosis construction, providing at the same time a system to monitor the anastomosis until complete healing. This may lead to reduced anastomotic leak rate and severity. This study aims to collect preliminary evidence on the effectiveness of C-REX to develop a future larger multicentric trial. The objective of the study is to provide preliminary data to determine whether the C-REX device may reduce the rate and severity of anastomotic leak after left colon and high rectal resection, providing new insights on the feasibility and effectiveness of the C-REX device in a real-word setting.

Target Recruitment
30
Inclusion Criteria
  • Patients ≥ 18 years old, men or women.
  • Planned primary resection due to colorectal neoplasia (cancer or benign polyps) of the sigmoid colon or rectum (above the peritoneal reflection) that require high anterior resection as the procedure of choice.
  • Patient indicated to elective minimally invasive sigmoid or high rectal resection.
Exclusion Criteria
  • Patients with pre-existing health conditions requiring surgery, such as intestinal obstruction or perforation, local or systemic infections, peritonitis, or intestinal ischemia.
  • Patients with preoperative evidence of distal metastasis.
  • Patients with documented intestinal or anal stenosis or other obstructions distal to the anastomosis.
  • Patients who received radiation therapy to organs in abdomen or pelvis unrelated to current colorectal condition.
  • Patients indicated to defunctioning ileostomy (intention to treat).
  • Any condition that, in the opinion of the investigator, may interfere with the study conduction. In particular, any condition which can cause significant alteration of colonic wall thickness such as chronic and repeated infection which may impair the use of C-REX.

Assess the rate of radiologically confirmed anastomotic leak in the C-REX arm

Secondary Outcome Measures
NameTimeMethod
Severity of anastomotic leaks90 days after surgery

Assess the severity of the anastomotic leaks, classifying the events according to the International Study Group of Rectal Cancer (ISGR) criteria in the C-REX arm

Time of anastomosis constructionIntraoperative

Assess the median time of anastomosis construction in the C-REX arm

Postoperative complications90 days after surgery

Assess the median Comprehensive Complication Index (CCI) in the C-REX arm

Positive C-REX integrity testsIntraoperative

Assess the rate of intraoperative positive C-REX integrity tests in the C-REX arm

Low Anterior Resection Syndrome90 days after surgery

Assess the median Low Anterior Resection Syndrome (LARS) score (ranging from 0 to 40, with 21 indicating significant symtpoms) in the C-REX arm.

Anastomotic stenosis90 days after surgery

Assess the rate of anastomosis stenosis, as assessed by the 90-day endoscopic evaluation in the C-REX arm

Helathcare costs90 days after surgery

Evaluate the median healthcare costs (direct and indirect) in the C-REX arm

Investigator's satisfactionIntraoperative

Evaluate the grade of investigator's satisfaction in using the C-REX device by using a simple likert scale ranging from 0 (completely unsatisfaid) to 5 (completely satisfaid).

Positive leak testsIntraoperative

Assess the rate of intraoperative positive leak tests in the C-REX arm
