To evaluate clinical impact and benefits of trans-sphincteric injection of silicone in patients with anal incontinence using validated incontinence score and quality of life scale. 35 incontinent patients related to internal and external anal sphincter defects were selected for ambulatorial trans-sphincteric silicone injection. Inclusion criteria were: anal incontinence associated or not to internal sphincter defects and/ or one quadrant external sphincter defects. All patients were submitted to clinical evaluation before and after injections including an incontinence scoring system (Cleveland Clinic Florida) and quality of life scale (Fecal Incontinence Quality of Life) with 4 domains: depression, self-perception, embarrassment and lifestyle. Results: 28 female and 7 male patients with a mean age of 60.3(19-80) years underwent ambulatorial trans-sphincteric injection of silicone. Mean incontinence score improved significantly after injection: 11.3 to 4.3 (p<0.001). All domains in the quality of life scale demonstrated significant improvement after injection (p<0.0001). Conclusion: In selected cases, trans-sphincteric silicone injection is a valuable option for the treatment of anal incontinence, improving significantly patient's quality of life.
