Abstract

Background: Anal fistula is a common disease in the anal-rectal area, ranking second after hemorrhoids with nearly 24.5% of diseases in this area. Understanding this disease with information such as epidemiological characteristics, clinical and paraclinical features, and diagnosis plays a very important role in treating this disease. Objective: Describe the clinical and paraclinical characteristics of patients with recurrent anal fistula at Can Tho Central General Hospital. Research method: Retrospectively describes over 80 patients who have been operated on at least once and are still not cured (including patients with previous surgeries at the lower level, and patients with abscess incisions) but have been diagnosed with a definite abscess, anal fistula. Results: Average age: 42.9 ± 14.86 (17 - 79), 31 - 50 years old accounted for 51.3%. Male/female ratio ≈ 6.3/1. The reason for admission to the hospital was anal discharge accounting for the majority with 66.3%. There are 75% of patients with 1 external opening, 66.7% of external openings are located in the back half, the distance from the external opening to the anal edge is from 2 to 4 cm, accounting for 76.4%. 86.1% found an internal hole, 77.8% had 1 internal hole, 76.8% were consistent with Goodsall's law. 15% (12 patients) had an MRI scan of the fistula with the results of all 12 patients having the internal hole and fistula location described on the MRI results. Regarding ultrasound, 45% of patients have combined lesions (abscess + fistula). According to fistula classification, 72.4% sphincter oblique fistula, 21.3% simple abscess, 6.3% complex fistula. Conclusion: It is necessary to identify the clinical and paraclinical characteristics of anal fistula disease and accurately classify the fistula with the right treatment to help prevent patients from having to undergo repeated surgery without referring the patient to the hospital. specialist line.
