Cutting of Sphincter in Fistulectomy with Primary Closure in Complex Fistula-in-Ano: Is it Feasible?

Abstract

Abstract Introduction Treatment of complex fistulas such as inter- or transsphincteric, recurrent, and high fistulae have high rate of recurrence or incontinence. Fistulectomy with primary sphincter reconstruction might represent an effective and safe alternative to reduce rate of recurrence and incontinence. The aim of this study is to assess incontinence and recurrence after fistulectomy with primary sphincter reconstruction for management of complex fistulas. Material and Methods There were 60 patients with complex fistulae involving the sphincter, with 56 male and 4 female, mean age 40.6 years, operated by fistulectomy and primary sphincter repair over a period of 7 years. Patients were followed up for 6months for any complications, recurrence, and incontinence. Results The majority of patients (50, 83.3%) had complete wound healing in 2 weeks, while 4 (6.6%) patients had hematoma and superficial wound dehiscence, which were managed conservatively and healed in 4 weeks. There was one recurrence. All patients had good continence postoperatively, except for mild fecal incontinence (FI, score 3), seen in 6 (10%) patients. However, all these patients regained continence within 6 weeks. Conclusions Primary reconstruction of anal sphincter with fistulectomy is a safe option for complex fistula-in-ano.
