Clinical Trial Summary

A randomised controlled feasibility study to compare two surgery techniques in the formation of a permanent end colostomy; the trans-peritoneal(TP) technique - currently, the most commonly used technique and the investigational extra-peritoneal(EP) technique, which has been reported in small studies to reduce the risk of parastomal hernia . This feasibility study will primarily aim to determine the feasibility viability of progression to a full multi-centre trial and test study design acceptability for participants. Participants will be asked to consent to be randomised to either the TP or EP procedure during surgery. Following surgery, participants will be followed up to a maximum of 12 months and asked to complete quality of life questionnaires (EQ5D and Colostomy Impact Score). Participant data will also be accessed by research teams at site to collect data on stoma appliance use and complications.

Description:

This feasibility study is a multi-centre, single (patient) blinded, randomised controlled trial (RCT). Co-ordination and trial management will be led from Swansea Trials Unit (STU). The study will take place across 3 sites: Swansea Bay University Health Board (SBUHB); Aneurin Bevan University Health Board and Cardiff and Vale University Health Board. Surgeons at all three sites have experience with both interventional extra-peritoneal surgical technique and the most commonly used transperitoneal technique. The investigators aim to recruit 60 participants over 12 months. Local recruitment will be co-ordinated by PIs and research teams. Recruitment is aimed to be equally distributed across all sites. Participants will be equally randomised by arm in each of the three sites: to receive the EP colostomy formation (Intervention) or the standard transperitoneal (TP) technique. Participants will remain blinded as to their treatment until the close of the study. Data collection will be performed by the clinical and research teams, with support from PIs. Data will be stored centrally in REDCap (Research Electronic Data Capture) software. The investigators will explore whether it is possible to establish a research infrastructure in which data can be collected and co-ordinated across sites and for patients to be followed up effectively. The investigators will also look to demonstrate standardisation of the operative technique for EP stoma formation and to determine which outcome measures a future trial should explore. This feasibility trial be evaluated against ACCEPT progression criteria.
