Initial Experience With Video-Assisted Anal Fistula Treatment in the Philippines.

Abstract

PurposeWe determined the outcomes of patients undergoing video-assisted anal fistula treatment (VAAFT) for fistulain-ano at the Philippine General Hospital.MethodsTwenty consecutive adult patients who underwent the VAAFT procedure from 2016–2018 were included in this investigation. Information detailing baseline demographic and clinical data, fistula type and classification, and previous surgeries were retrieved from in-hospital and operative records. Operative time, identification of the internal opening, method of internal opening closure, and occurrence of immediate postoperative complications were determined. The status of the fistula was assessed at one month, 3 months, and 6 months postoperatively based on outpatient follow-up records. The primary outcomes were healing rate and recurrence rate. Secondary outcomes were 30-day morbidity, postoperative complications, and incontinence using the Wexner score.ResultsEighteen patients (90%) had a preoperative diagnosis of complex fistula, and 13 patients (65%) had undergone a previous fistula surgery. Primary healing rate was 55% at 1 month, 63.16% at 3 months, and 78.95% at 6 months postoperatively. Eighteen patients (94.74%) maintained continence (Wexner score = 0) at 6 months.ConclusionOur study results suggest that VAAFT is a safe, minimally invasive technique for treatment of anal fistula and can preserve anal sphincter function. The technique has an acceptable healing rate with minimal complications.
