Mo2009 Factors Associated With Fecal Incontinence and Quality of Life After Perianal Surgery for Cryptoglandular Fistulas

Introduction: Surgical management of perianal fistulas remains a challenge as consequences of repetitive anal surgery can cause profound morbidity and impair experienced quality of life (QOL). In recent years new sphincter sparing procedures such as ligation of the intersphincteric fistula tract (LIFT) have been implemented potentially lowering the chance of developing fecal incontinence (FI). Aim: This study evaluated factors associated with FI and impact on QOL after surgical treatment for perianal sepsis. Methods: All patients with cryptoglandular perianal fistulas who underwent pre-operative endoanal ultrasound (EAUS) between 2002 and 2012 at our tertiary centre and in a local clinic specialised in proctologic surgery were sent questionnaires regarding FI (Wexner (WX)and Vaizey (VS) score) and impact of FI on QOL (FIQL) in October 2013. Data was abstracted regarding patient's demographics and all surgical procedures ever received for perianal sepsis. Predictor variables analysed were sex, age of first complains, age at follow up, fistula type, fistula ramifications, no. of perianal abscesses surgically incised and drained (I&D) (0, 1, or > 1), no. of fistulotomys received (0, 1 or > 1) and no. of sphincter sparing procedures (mucosal advancement flap or fistulectomy) received (0, 1 or 2, or > 2). The likelihood of each of these outcomes was estimated by using a multivariate regression model. The correlation coefficient was calculated
