SP1.1.4The Walking Thread – What happens to fistula-in-ano patients who are lost to follow up? A Service Improvement Study
Abstract Aims Management of perianal abscess and resultant fistula-in-ano remains controversial. Studies suggest that 1/3 of idiopathic cryptoglandular abscesses can result in fistula-in-ano. Our current practice is to incise and drain primary abscesses and for patients to return as necessary. Known fistula patients will be appointed for Examination Under Anaesthetic (EUA) at 6-12 weeks. Does this result in best management or do they become “elective emergencies”? Methods A retrospective audit of management of fistula-in-ano over 4 years was conducted, utilising precollected data of Cryptoglandular abscesses, excluding inflammatory, radiation or malignant causes. Patients lost to follow up were analysed including presentation, fistula diagnosed at first or subsequent attendance, number of operations, number of attendances and seton placement. Results 512 patients underwent operations for cryptoglandular abscess causing fistula-in-ano between 2013 and 2017. 10% (N = 50) were lost to follow up despite documented follow up plans for 32. Of these, 18 were elective attendances, 14 emergency. 24 of the 32 had a Seton sited prior to being lost to follow up. Conclusions The various presentations (emergency, elective, clinic) and waiting lists mean these patients are presenting as emergencies whilst awaiting follow-up. Many are simply lost to follow up, with Setons in-situ. We propose a fortnightly hot-clinic system, run by second on-call registrars to assess and manage these patients. This would provide an elective clinic to allow single point of access to fistula-in-ano patients ensuring prompt follow-up and reduction in unnecessary EUA, as well as improving senior colorectal trainees exposure to perianal disease and its management.
