DUBE, GQ et al. Thirteen-year audit of the management of anorectal fistulae in a tertiary colorectal unit. S. Afr. j. surg. [online]. 2022, vol.60, n.4, pp.235-241. ISSN 2078-5151.

BACKGROUND: Persistent anorectal fistulae are referred for assessment in the Durban Metropolitan area to the colorectal unit at the tertiary hospital. This audit aimed to report the assessment and management of these fistulae to benchmark the outcomes from these approaches at a South African tertiary colorectal unit METHODS: Retrospective analysis of prospectively collected data of patients with anorectal fistulae over a 13-year period at a tertiary referral centre. Data analysed included demographics, clinical presentation, comorbidity, management and outcome. Study outcomes measures were healing time and secondary outcome measures were complications of surgery RESULTS: One hundred and thirty-three patients (median age 44 and M:F ratio 2.8:1) with 206 fistulae were accrued. The initial assessment and diagnostic procedures included insertion of seton (126), fistulectomy (14), and fistulotomy (65). Definitive procedures included two-stage seton fistulotomy (43), ligation of the inter-sphincteric fistula tract (LIFT) procedure (39), modified Hanley procedure (17), and mucosal advancement flap (5). One patient had no surgery and nine did not undergo a definitive procedure. Additional procedures included anal sphincter reconstruction (2) and repair of rectovaginal fistula (2). Residual anal incontinence occurred in 13.5%. The failure rate was 6% and healing occurred in 94%. The median healing time was 8 months after the initial surgery and 4 months following the definitive procedure CONCLUSION: The fistula healing rate overall was 94% and was associated with an incontinence rate of 13.5%
