Comparing two techniques of skin closure, purse string closure and linear closure, in terms of the incidence of surgical site infection in adults undergoing elective reversal of ileostomy

Skin closure technique for ileostomy reversal, purse string closure. This intervention is used once on each participant in this arm of the study. The intervention involves the technique used for skin closure during the elective operation to reverse the participants ileostomy. This intervention is definitive method of closure of the skin after reversal of the participants ileostomy, it is a permanent procedure. The follow up period for detection of surgical site infection (the primary outcome measure) is 30 days post surgery. Patients will be followed up for as much as a further 2 years to assess the secondary outcome measure, cosmetic result. "Purse string closure" differs from the comparator treatment "linear closure" in terms of the technique use for closure of the skin following the reversal of ileostomy. "Purse string closure" involves a suturing technique that draws the skin together in a circular fashion, in contrast to "linear closure" which abuts the edges of the skin defect, and sutures them closed in a traditional linear fashion.
