Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: At the time of stoma reversal or resiting, the intervention group will have Gore BioA synthetic absorbable tissue reinforcement placed by the operating surgeon in either the pre-peritoneal (retro-rectus) space or deep to the anterior fascia of the abdominal wall at the site of the stoma reversal. The recto-rectus position is preferred. If Gore BioA is to be placed in the retro-rectus position, after developing the pre-peritoneal space, the peritoneum will be closed with 2-0 or 3-0 PGA sutures at the discretion of the surgeon. Ideally the space created should be adequate to place the Gore™ BioA™ FS0808 (8 x 8cm). The Gore BioA is to be secured with 4 x 3-0 polydioxanone sutures. Suture closure of the fascia will be performed with interrupted 0 polydioxanone sutures. The additional time required to place and secure the mesh is estimated to be 10 minutes.

Outcomes
Primary outcome [1] 305234 0
Incisional hernia formation at the site of the stoma one year following stoma reversal or re-siting. An incisional hernia will be defined according to the European Hernia Society definition as “any abdominal wall gap with or without a bulge in the area of post-operative scar perceptible or palpable by clinical examination or imaging”. Classification of incisional hernias will be by size, location and reducibility of the contents. This will be assessed by clinical examination in the surgeon's rooms or the outpatients clinic and by abdominal ultrasound at one year following surgery.
Timepoint [1] 305234 0
1 year
Primary outcome [2] 305235 0
Incisional hernia formation at the site of the stoma three years following stoma reversal or re-siting. There is an ongoing risk of incisional hernia formation after surgery with time. An incisional hernia will be defined according to the European Hernia Society definition as “any abdominal wall gap with or without a bulge in the area of post-operative scar perceptible or palpable by clinical examination or imaging”. Classification of incisional hernias will be by size, location and reducibility of the contents. This will be assessed by clinical examination in the surgeon's rooms or the outpatients clinic and by abdominal ultrasound at three years following surgery.
Timepoint [2] 305235 0
3 years
Secondary outcome [1] 344552 0
Surgical site infection. SSI will be defined according to the Centre for Disease Control (CDC) definitions for surgical site infection surveillance. This will be assessed prior to discharge and at a post-operative follow-up visit at approximately 30 days (range 4 - 6 weeks)
Timepoint [1] 344552 0
30 days
Secondary outcome [2] 344553 0
Superficial wound dehisence. Superficial wound dehiscence will be recorded if a previously closed wound opens spontaneously and may not necessarily be associated with the presence of a SSI. This will be assessed prior to discharge and at a post-operative follow-up visit at approximately 30 days (range 4 - 6 weeks).
Timepoint [2] 344553 0
30 days
Secondary outcome [3] 344554 0
Deep wound dehiscence. Deep wound dehiscence will be recorded if there is clinical evidence of dehiscence of the abdominal wall fascia defined as visualisation of separation of the abdominal wall fascia either at clinical examination or at reoperation. The identification of abdominal viscera in the wound base also equates to deep wound dehiscence. This will be assessed prior to discharge and at a post-operative follow-up visit at approximately 30 days (range 4 - 6 weeks)
Timepoint [3] 344554 0
30 days
Secondary outcome [4] 344555 0
Operating time. The start and finish times of the operation are recorded on the operating count sheet by the scrub nurse in charge of the procedure. This information will be collected by the research team.
Timepoint [4] 344555 0
1 days
Secondary outcome [5] 344556 0
Re-operation. Will be defined as an operation to treat post-operative complications associated with the stoma reversal or resiting within 30 days. This outcome will be recorded by the researchers on patient discharge from hospital.
Timepoint [5] 344556 0
30 days
Secondary outcome [6] 344557 0
Re-admission. Any requirement for the patient to be re-admitted to a hospital to manage a complication of the stoma reversal or resiting operation will be recorded by the research team.
Timepoint [6] 344557 0
30 days
Secondary outcome [7] 344558 0
Wound haematoma. A wound haematoma will be defined as a large collection of blood clot at the surgical wound site. Small volumes of blood on surgical dressings will not be included. This will be assessed prior to discharge and at a post-operative follow-up visit at approximately 30 days (range 4 - 6 weeks).
