Fecal incontinence is a common symptom found in pathologies of organic and functional origin. Incontinence affects the quality of life of the patient, self-esteem and social inclusion. During the last 2 years in the IMSP Mother and Child Institute, the National Practical Scientific Center of Pediatric Surgery Academician "Natalia Gheorghiu" 107 children with fec incontinence of different degree were examined of which 9 children had post-traumatic sphincter dysfunction. We describe the clinical case of a 13-year-old boy who suffered a road accident, following which he chooses with: fracture of the right femur; bruised wound of perineum imply external and internal anal sphincter, rectal ampulе; contusion of the abdominal organs; post-traumatic shock. Surgery was performed for the perineal plastic reconstruction with own tissues, under the protection of the colostoma. The infected wound, with a length of 11 cm, a depth of 9-10 cm which penetrated into the perirectal space, simultaneous hurts the colorectal apparatus. Over 3 months the clinical-paraclinical examination was performed, ano-rectal revision, ano-rectal manometry, anal canal profilometry were performed and electromyography of the external anal sphincter. A regeneration with keloidal scar was determined on the region of the wound, the positive rectoanal inhibitory reflex, the sensitivity present at the filling of 15-20 ml of air, the profilometry of the anal canal determined the asymmetry of the channel on the scar area, with the pressure decrease up to 25 mmHg on the affected side, the contraction of the external anal sphincter decreased by 40% in the affected quadrant compared to the intact one. The results obtained after the postoperative neurophysiological examination of the rectal region, showed us that this child, previously healthy, with normal fecal continence, has a possible fecal incontinence after stoma removal. Aft examining the child more than 2 months after the surgery, we determined that he has daily defecation, with normal stool and episodes of fecal incontinence (on average 2 times/week). Perineal trauma with colorectal aparatus afection had an increased risk for the occurrence of fecal incontinence, despite adequate surgical sphincteroplasty, which will requires specialized individual treatment for each patient apart.
