Total fistulectomy, sphincteroplasty and closure of the residual cavity for trans-sphincteric perianal fistula in the elderly patient

Perianal fistula is a complex and frequent disease. At present, no treatment nor technique has shown an absolute superiority in terms of efficacy and recurrence rate. The technique has to be chosen considering the balance between faecal continence preservation and disease eradication. Rarely concomitant perianal abscess and fistula are treated at the same time, and often time to complete recovery is long.
The aim of this study was to evaluate the possibility of treating the abscess and the fistula tract in one procedure with total fistulectomy, sphincteroplasty and an almost complete closure of the residual cavity, thus reducing the healing time in older patients.
A non-randomized single-centre series of 86 patients from 2007 to 2012 with low–medium trans-sphincteric perianal fistula (< 30% of external sphincter involvement) with or without synchronous perianal abscess were treated with total fistulectomy, sphincteroplasty and closure of the residual cavity technique.
Success rate was 97.7% with a healing time of 4 weeks; overall morbidity was 16.2%; recurrence rate was 2.3%; no major alterations of continence were observed.
Fistulectomy, sphincteroplasty and closure of the residual cavity are associated with a low rate of recurrence and good faecal continence preservation in older patients. This technique can be safely used even with a concomitant perianal abscess, with reduction in healing time and in the number of surgical procedures needed.
Total fistulectomy with sphincteroplasty and partial closure of the residual cavity, as described, is a safe procedure but has to be performed by dedicated colorectal surgeons.
