A patient aged under 65 at the time of the primary curative resection carries a 2% 5-year risk of metachronous cancer, implying that 3 year surveillance colonoscopy is justified. Whereas patients aged over 75 carry less than a 2% 10-year risk, implying that it is seldom warranted to repeat the colonoscopy more frequently than every 5 years. A stratified approach to the frequency of surveillance colonoscopy requires further consideration.

Surgical site infection (SSI) is associated with increased morbidity, length of stay, and cost. Cyanoacrylate glue is a low‐cost, fluid‐proof, antimicrobial barrier. The aim of this systematic review is to assess the use of cyanoacrylate glue after standard wound closure versus dressings in the reduction of SSI. Medline, Embase, Cochrane Library, and clinical trial registries were searched with no restrictions in accordance with PRISMA guidelines. Eligibility criteria were prospective studies comparing glue versus dressings after standardised wound closure. Two reviewers independently screened articles and utilised GRADE for quality assessment. Meta‐analysis was not performed because of the heterogeneity of the data. Three articles were included in the review. Study quality was uniformly low. Incidence of SSI was low, between 0% and 4%. No significant differences were reported in the single randomised controlled trial. A single non‐randomised parallel group trial reported a significant reduction in the incidence of SSI in the cyanoacrylate group. There was no consistent evidence demonstrating reduction in SSI as a result of the use of cyanoacrylate glue. Future studies should assess the use of cyanoacrylate in procedures with a higher rate of SSI, for example, lower limb bypass.
