Brief summary

The purpose of this study is to evaluate safety of Seal-G MIST System in reinforcing colorectal anastomosis, in subjects undergoing colorectal surgery.

Detailed description

Study procedures: Pre-surgery: * Screening will be performed among adult subjects who are scheduled for an elective colorectal surgery. Once potential eligibility to the study is determined based on the study's inclusion/exclusion criteria, study procedures will be explained to the candidate and participation will be offered. * Informed consent process. * Pre-surgery assessments will be according to the routine practice at the site and determined by the treating physician. Intra-operative: * During the surgery, after confirmation of the intra-operative exclusion criteria, completion of anastomosis creation and only after leak test was performed , subjects will be allocated to one of the two treatment arms with a 1:1 ratio based on a randomization scheme (either to the Standard of care (SOC) or to Seal-G MIST arms). * Device (Seal-G MIST System) application (to Seal-G MIST treatment arm only). Post-operative follow-up: * Subjects will be followed during post-operative period until discharge from the hospital for clinical and subclinical leaks according to the SOC. * In an event of suspected anastomotic leak, patient will be treated according to severity of leak and PI clinical judgement (conservative treatment, drainage, diversion, anastomosis take down). * Subjects will be followed up for leaks and related AE/SAEs at the day of the surgery and for a period of 15 weeks (±2 weeks) post-surgery, including the following activities: * Daily while hospitalized (in accordance with the site routine procedures) * At 1 month (±1 week) and 15 weeks (±2 weeks) post-surgery (Hospitalization for elective procedure (i.e. chemotherapy treatments) will not be considered as SAEs)

Interventions

Seal-G MIST is an adjunct device that will be applied adjunctively to cover standard closure techniques.

SINGLE (Subject)

Masking description

This study is single blinded. The subject will be blinded to the treatment arm; however, by nature of the type of the proposed study, blinding of the investigator/ surgeon is not feasible. In order to minimize bias, subjects will be randomized during the surgery upon confirmation of the intra-operative exclusion criteria. This will ensure that the surgeon will not know prior to surgery and until completion of anastomosis creation, whether or not Seal-G MIST will be used.

Secondary

MeasureTime frameDescription
Incidence of subclinical/ radiological leaksup to 15 weeks (±2 weeks) post-surgeryAs assessed from Adverse event/Serious Adverse Event reporting form
Incidence of Serious Adverse Events (SAE) complicationsup to 15 weeks (±2 weeks) post-surgeryAccording to Serious Adverse Event (SAE) definition from Medical Device Directive (MEDDEV 2.7/3, Rev 3, May 2015)
Incidence of collection/abscess without demonstrated leakup to 15 weeks (±2 weeks) post-surgeryAccording to Adverse event reporting form
Incidence of clinical anastomotic leaksup to 15 weeks (±2 weeks) post-surgeryAnastomotic leak (AL) is defined as evidence of a defect in the intestinal wall integrity at the anastomotic site leading to local or general peritonitis, abscesses in the proximity of the anastomosis and/or fistula, fecal or purulent discharge from drains.
Incidence of postoperative mortalityup to 15 weeks (±2 weeks)
Hospital length of stayFrom date of surgery until the time for Ready to be discharged (in days), an average of 10±4 days
Incidence of deployment failureduring surgeryonly for treatment arm
