INTRODUCTION:
Through the past decades, various surgical techniques have been introduced as modern modalities for the treatment of perianal fistula, to provide an effective and minimally invasive option in comparison with the conventional lay open technique which is thegold standard surgical treatment.

AIM:
The aim of this study was to compare two different techniques for management of simple perianal fistula which are FiLaCTM combined with LIFT as a modern technique vs classic lay-open technique as regarding the following parameters: -
incidence of postoperative painusing Visual Analogue Scale pain scoring (VAS), duration needed for wound healing, fecal incontinence using Cleveland Clinic Fecal Incontinence Severity Scoring System(CCIS), quality of life using Global Quality of Life Scale and recurrence. The last three parameters were assessed till six months post-operative.

PATIENTS AND METHODS:
This study was conducted at Alexandria Main University Hospital. Sixty cases withsimple trans-sphincertric perianal fistula were enrolled in our study, thirty cases were treated with FiLaCTM+ LIFT (group A) and thirty cases with classic lay open (group B). Assessmentof postoperative pain for one month and duration needed for wound healing were reported. Also assessment offecal incontienece,quality of life and recurrence were recorded for six months and all the data was analyzed.
