Video-assisted anal fistula treatment versus fistulectomy and sphincter repair in the treatment of high cryptoglandular anal fistula: a randomized clinical study.

ABSTRACT:

Background

Video-assisted anal fistula treatment (VAAFT) may have a recurrence rate comparable to that of fistulectomy and sphincter repair (FSR) in the treatment of high anal fistula and with potential advantages in wound healing, functional outcome and quality of life. The aim and objectives of the study are to compare the outcome of VAAFT with that of FSR for high cryptoglandular anal fistula.

Methods

This was a single-centre randomized controlled trial of adults with high anal fistula comparing FSR with VAAFT. Primary outcome was fistula recurrence. Secondary outcomes were results of anal manometry, quality of life and faecal continence. A power calculation of 33 patients in each arm (1 : 1) was based on recurrence in the FSR and VAAFT groups of 5 per cent and 30 per cen
