Seal-G Safety Study

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02825173
Recruitment Status : Completed

Brief Summary:
The purpose of this study is to farther assess the safety of the Seal-G Surgical Sealant for the reinforcement and protection of gastrointestinal anastomosis.

Condition or disease Intervention/treatment Phase
Elective Surgical Procedures, Digestive System Device: Seal-G Not Applicable

Detailed Description:


Screening will be performed among adult subjects who are scheduled for an elective colorectal surgery. Pre-surgery assessments (after completion of consent process and signed ICF) will be according to the routine practice.


During surgery, an assessment of the intra-operative exclusion criteria will be performed. If the subject does not meet any of the exclusion criteria, the subject will be further enrolled. Surgery will be performed according to the site standard of care (routine practice). Anastomosis will be created either using a stapler device (linear or circular), according to manufacture IFU (Instructions for use) or hand suture according to surgeon best practice technique. Once anastomosis has been created, surgeon will verify the anastomosis and mucosal donuts integrity.

Device (Seal-G) application on anastomotic site

Post-operative follow-up: Follow-up evaluations will be performed daily while hospitalized. There will be one postoperative follow up at one month - clinic visit

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective, Multi-center, Open Label, Non-randomized Study, of Seal-G Surgical Sealant for the Reinforcement of Gastrointestinal Anastomosis
Study Start Date : August 2016
Actual Primary Completion Date : November 2016
Actual Study Completion Date : December 2, 2016

Arm Intervention/treatment
Experimental: Seal-G
A surgical sealant intended for use as an adjunct to standard closure techniques for reinforcement and protection of gastrointestinal anastomoses.
Device: Seal-G


Device: Seal-G Seal-G is applied adjunctively to cover standard closure techniques

Other Name: Seal-G Surgical Sealant

Primary Outcome Measures :
  1. Rate of device related complications [ Time Frame: Postoperative to end of follow up (30±7 days) ]

Secondary Outcome Measures :
  1. Overall rate of complications [ Time Frame: Postoperative to end of follow up (30±7 days) ]
  2. Postoperative length of hospitalization stay [ Time Frame: Postoperative till time for "ready to be discharged" (10±4 days) ]
  3. Duration of sealant application [ Time Frame: Intraoperative: starting from initial spreading on the treatment site to completion of curing, will be recorded (in minutes) ]
  4. Ease of use of the device [ Time Frame: Intraoperative: device application ]
    Ease of use of the device will be rated using a Likert scale from 1 to 5 with: 1 being Very easy, 2 Easy, 3 Neutral, 4 Difficult and 5 being Very difficult. At the day of surgery (after surgery completed) the surgeon will complete a questionnaire regarding the device use and ease of application.
