Plain English Summary

Background and study aims
A stoma is an opening on the outer surface of the abdomen that is surgically created after removal of part of the bowel or urinary system to divert urine or feces into an external pouch. A parastomal hernia occurs when a weakness in the abdominal wall muscles allows tissue to protrude out, creating a bulge around the stoma. The aim of this study is to find out whether creation of the stoma trephine by a stapling technique together with mesh reinforcement can simplify the reinforcement procedure and reduce the incidence of parastomal herniation compared to standard techniques, whether the stoma is constructed by open or laparoscopic (keyhole) techniques.

Who can participate?
Patients aged 18 and over who require a permanent stoma due to bowel disease

What does the study involve?
Participants are randomly allocated into two groups. One group undergoes standard stoma formation with no reinforcement. The other group receives a stapled trephine with mesh reinforcement. This involves use of a circular stapling device to form and simultaneously reinforce the abdominal wall stoma with mesh. The rate of parastomal herniation is assessed at 24 months after surgery.

Scientific titleA randomised controlled trial of Stapled Mesh stomA Reinforcement Technique (SMART) versus standard technique to assess effect on parastomal herniation
Study acronymSMART
Study hypothesisCreation of the stoma trephine by a stapling technique together with mesh reinforcement can simplify the reinforcement procedure and reduce the incidence of parastomal herniation compared to standard techniques, irrespective whether the stoma is constructed by open or laparoscopic techniques.

ConditionParastomal herniation
InterventionPatients who require permanent colostomy or ileostomy will be randomised into two groups:
1. Standard stoma formation, no reinforcement
2. Stapled trephine with mesh reinforcement. This involves use of a circular stapling device (Compact , Frankenman) to form and simultaneously reinforce the abdominal wall stoma with mesh
Intervention typeProcedure/Surgery
Primary outcome measureCurrent primary outcome measures:
The rate of clinically evident parastomal herniation at 24 months post operatively, as assessed by a local investigator blinded to treatment allocation

Previous primary outcome measures:
1. The rate of clinical herniation evaluated clinically at discharge and at 1, 12, 24 and 60 months post operatively
2. The radiological incidence of herniation detected by computerised tomography (CT) scan at 12, 24 and 60 months after surgery
Secondary outcome measuresCurrent secondary outcome measures:
1. The rate of clinically evident parastomal herniation evaluated at all other time points (annually up to a maximum of 5 years), as assessed by a local investigator blinded to treatment allocation
2. The rate of herniation as detected by computerised tomography (CT) scan or other radiological examinations of the abdomen, evaluated at 12 and 24 months after surgery
3. Harms including perioperative morbidity (assessed clinically at hospital discharge and at 6 weeks), 30-day mortality and long-term complications
4. The ease of the technique compared with the standard technique, evaluated by bespoke surgeon questionnaire at surgery
5. Quality of life assessed using EuroQol EQ-5D-3L questionnaires preoperatively and at 12 and 24 months post-operatively

Previous secondary outcome measures:
1. Complications associated with the techniques used for the procedures, evaluated at discharge and at 1, 12, 24 and 60 months post operatively
2. The ease of the technique compared with the standard technique
3. Cost/benefit analysis comparing the cost of the stapled reinforcement technique with Vypro® mesh to the standard technique
4. Quality of life assessed using SF36 version 2 and EuroQol EQ-5D questionnaires preoperatively and at 1, 12, 24 and 60 months post-operatively
