RESUMO
PURPOSE: Anal abscesses are common and, despite correct treatment with surgical drainage, carry the risk of developing fistulas. Studies identifying risk factors for the development of anal fistulas are sparse. This study aimed to identify the risk factors for anal fistulas after anal abscess surgery. METHODS: This was a multicentre, retrospective cohort study of patients undergoing acute surgery for anal abscesses in the Capital Region of Denmark between 2018 and 2019. The patients were identified using ICD-10 codes for anal abscesses. Predefined clinicopathological factors and postoperative courses were extracted from patient records. RESULTS: A total of 475 patients were included. At a median follow-up time of 1108 days (IQR 946-1320 days) following surgery, 164 (33.7%) patients were diagnosed with an anal fistula. Risk factors for developing fistulas were low intersphincteric (OR 2.77, 95CI 1.50-5.06) and ischioanal (OR 2.48, 95CI 1.36-4.47) abscesses, Crohn's disease (OR 5.96, 95CI 2.33-17.2), a history of recurrent anal abscesses (OR 4.14, 95CI 2.47-7.01) or repeat surgery (OR 5.96, 95CI 2.33-17.2), E. coli-positive pus cultures (OR 4.06, 1.56-11.4) or preoperative C-reactive protein (CRP) of more than 100 mg/L (OR 3.21, 95CI 1.57-6.71). CONCLUSION: Several significant clinical risk factors were associated with fistula development following anal abscess surgery. These findings are clinically relevant and could influence the selection of patients for specialised follow-up, facilitate expedited diagnosis, and potentially prevent unnecessarily long treatment courses.

A tailgut cyst is a rare tumour originating from the embryonic remnant of the retrorectal space. The cyst is often asymptomatic, but it can cause abdominal or rectal pain and urogenital symptoms. When diagnosed, resection is the choice of treatment, and traditionally open surgery has been preferred. In this case report, we present a 30-year-old female patient with a painful tailgut cyst. She was found to be candidate for transanal endoscopic microsurgery, which was successfully performed.

Anal abscesses are well-known conditions worldwide. The golden standard of acute treatment is incision and drainage. Knowledge of the anatomy of the anal area and the abscess involvement of perianal spaces is crucial in order to perform safe and correct surgical treatment as summarised in this review. Pre- and perioperative imaging with magnetic resonance imaging, endoanal ultrasonography or CT facilitates correct incision and drainage, while antibiotics as conservative approach have no place in the treatment of abscesses. One third of the patients have an underlying fistula, and if suspected referral to a fistula centre is warranted.
