Brief Summary:
Adhesions develop in more than 90% of patients undergoing an intra-abdominal surgical leading to serious consequences and complications at reoperation.
The investigators initiate a prospective, randomized, controlled, multicenter trial to assess whether the use of C-Qur™ Film decreases the incidence of adhesion formation in subjects undergoing colorectal surgery. Treatment with the application of C-Qur™ Film as an adhesion prevention barrier for colorectal surgery will be compared with the control group at the second stage ostomy takedown procedure. The primary outcome evaluation will be assessment of adhesions to the incision site.

The primary outcome evaluation will be assessment of adhesions to the incision site.
Detailed Description:
Rationale:
Adhesions are fibrous bands that connect tissue surfaces where anatomical connections do not normally exist. Adhesion tenacity appears to be related to maturity, as they can be filmy or heavily vascularized with sensory nerve fibers. Adhesions are formed after a tissue surface has been injured (abrasion, desiccation, lysis, etc.) and the subsequent process of fibrinolysis is interrupted. Adhesions develop in more than 90% of patients undergoing an intra-abdominal surgical procedure. The clinically relevant symptoms of adhesion formation are small bowel obstruction, secondary infertility and pain. Other consequences and complications of postsurgical intra-abdominal adhesion formation include inadvertent enterotomy and increased dissection time due to adhesiolysis during repeat surgery. The C-Qur™ Film offers reduction of adhesion formation and the corresponding potential reductions in small bowel obstruction, secondary infertility, pain and incidence of enterotomies and prolonged dissection time during subsequent abdominal surgery.
Objective:
The primary objective is to assess whether the use of C-Qur™ Film decreases the incidence of adhesion formation in subjects undergoing colorectal surgery with a temporary loop ileostomy or loop/split colostomy. Treatment with the application of C-Qur™ Film as an adhesion prevention barrier for colorectal surgery will be compared with the control group at the second stage ostomy takedown procedure. The primary outcome evaluation will be assessment of adhesions to the incision site.
Safety objective is to assess the number and type of post-operative complications.
Study design:
This is a prospective, physician initiated, randomized, controlled, multicenter trial. Eligible subjects undergoing colorectal resection requiring temporary loop ileostomy or loop/split colostomy by laparotomy or hand assisted laparoscopy will be included in the trial. Before closure, patients are randomized 1:1 to either the treatment arm (C-Qur™ Film) or control arm (no adhesion barrier). Subjects will return 8-16 weeks post-colorectal resection to have their loop ileostomy or colostomy surgically taken down. During the loop ileostomy/colostomy takedown, adhesions will be evaluated for incidence, extent, and severity.
Study population:
Males and females 18 years of age or older, undergoing elective open or hand assisted laparoscopic colorectal resection for any colorectal disease with the formation of a temporary loop ileostomy or loop/split colostomy.
Intervention:
In subjects assigned to the treatment arm, the C-Qur™ Film must be applied under the incision. Preferably it is also applied to other areas considered to be adhesiogenic, except the anastomosis. The number of C-Qur™ Film sheets placed in the abdomen is limited to a maximum area of coverage of 774cm2 (Please refer to Table 2 in section 6.6 for the maximum number of sheets for each size).
Main study parameters/endpoints:
The primary endpoint is the incidence of adhesions to the incision site in subjects undergoing colorectal surgery with a temporary loop ileostomy or loop/split colostomy.
Secondary endpoints include:
* Incidence of adhesions to the loop ileostomy or colostomy site
* Extent and severity of adhesions to the incision site
* Extent and severity of adhesions to the loop ileostomy or colostomy sites
* Duration of ileostomy takedown from the start of the takedown to the time the bowel is repositioned in the abdomen
* Percentage (%) of abdominal wall with adhesions
Safety:
• Type and frequency of surgical and medical complications, including all types of surgical site infections
