Aim: To compare the surgical management of perianal abscesses carried out by Basic Surgical Trainees (BSTs) and Higher Surgical Trainees (HSTs).Subjects and methods: The study comprised two groups of subjects: 50 BSTs (Group 1) and 50 HSTs (Group 2). All participants were interviewed regarding their preferred method of 'incising and draining' perianal abscesses. This was done by means of a telephone questionnaire. The data was recorded and sorted using Microsoft Excel. The results were compared with the consensus view of four colorectal surgeons which identified a 'gold standard' method of surgical management. Statistical analyses were carried out using Prism. P values less than 0.05 were considered significant. Results: All subjects completed every section of the questionnaire. Only 10% of BSTs and 12% of HSTs met the 'gold standard' as defined by the consultant surgeons. There was no statistical difference in the responses given by the two groups with regard to choice of anaesthesia; incision; curettage, de-roofing and packing of cavity; probing for fistulae, rectal examination and follow up. HSTs tend to send tissue for histology (p=0.003), whilst BSTs were more likely to washout the cavity (p=0.023). In addition, responses given by trainees within their groups were also not consistent. Conclusion: There is a need for a protocol for incision and drainage of perianal abscesses, which is one of the most common emergency procedures undertaken by surgical trainees. Introduction A perianal abscess is the suppuration of tissues in the perianal space. The majority are caused by cryptoglandular infection 1,2,3 but other causes include Crohn's disease, malignancy and tuberculosis.4 The first event is infection of the anal glands, which spreads to the intersphincteric space and then extends to emerge at the border of the anal canal as a perianal abscess. Although this affects all age groups, there is a larger incidence in patients between the age of 30 and 49 years.5 Incision and drainage of perianal abscesses is one of the most common unsupervised procedures carried out by surgical trainees. Simple drainage of an abscess leads to immediate symptomatic relief but other procedures should be carried out in order to optimise the treatment and reduce the risk of recurrence. Several methods have been described in the literature, which include; traditional incision, drainage and packing,4 drainage and primary fistulotomy,6,7 de Pezzer catheter drainage,8,9 and incision, drainage and primary suture with or without local antibiotic.10,11 There seems to be no general consensus regarding the optimal surgical management of this condition. This telephone survey was performed to compare the techniques of simple incision and drainage of perianal abscesses between surgical trainees, and also against the ‘gold standard' treatment identified by four consultant surgeons. Subjects and Methods 50 BSTs and 50 HSTs were selected at random via the different hospital switchboards in the London region and interviewed by telephone using the questionnaire (see Appendix). Staff grades were excluded from the survey due to the diversity in their baseline training. The data was recorded and sorted using a Microsoft Excel spreadsheet. Statistical analyses were carried out using Prism. A p value less than 0.05 was considered significant. All participants completed every section of the questionnaire and there were no refusals. Four Consultant Colorectal Surgeons were interviewed regarding their preferred method of incision and drainage. The trainees' responses were then compared with this ‘gold standard' of surgical management. Results The representation from different years amongst BSTs and HSTs is shown in Figure 1 below.The results from different sections of the questionnaire are outlined below.
