[Home training as a treatment of faecal incontinence and sphincter dyssynergia]. / Entrenamiento anorrectal domiciliario como tratamiento de la encopresis y disinergia esfinteriana.

OBJECTIVE: The defecation disorders represents the 3% of consultations in pediatrics patients. Our goal was to demonstrate the effectiveness and efficiency of the reeducation of the defecation maneuver through home training in patients with encopresis and sphincter dyssynergia. MATERIAL AND METHODS: Study of patients with fecal incontinence treated with home training at our center between 2014-2015. Anorectal manometry was performed and was valued defecation maneuver by expulsion of rectal probe with or without the ball. Daily sessions were performed using a Foley catheter (18-20Fr.) with progressive filling of the balloon, maximum 20cc. The response to the treatment was assessed in terms of episodes of soiling. RESULTS: Seven patients (6 males and 1 female) with a mean age of 9.7 years (range, 5-15) were included; two patients with anorectal malformation history, 1 Hirschsprung disease, 1 sacrococcygeal teratoma and 3 functional encopresis. Three patients had soiling episodes daily and 4 patients frequently. The mean basal pressure of anal channel was 32.34mmHg (range, 11.74-50.75) with negative defecation maneuver in 2 cases, deficient in 3 and dyssynergic in 2 patients. The mean time of biofeedback therapy to be asymptomatic was 5.14 months (range, 2-11), with a mean of 16.14 months (range, 3-24), with the 7 patients currently maintained clean. CONCLUSIONS: The present study suggests that re-education of defecation maneuver through home training, seems to be an effective and efficient therapy, achieving excellent results in medium term.

OBJETIVO: Los trastornos de la defecación representan el 3% de las consultas en pediatría. Nuestro objetivo fue demostrar la eficacia y eficiencia de la reeducación en la maniobra defecatoria mediante el entrenamiento domiciliario en los pacientes con encopresis y disinergia esfinteriana. MATERIAL Y METODOS: Estudio de los pacientes con encopresis tratados mediante entrenamiento domiciliario en nuestro centro entre 2014-2015. Se realizó manometría anorrectal y fue valorada la maniobra defecatoria mediante la expulsión o no de la sonda rectal con o sin balón. Se realizaron sesiones diarias de forma domiciliaria empleando una sonda de Foley (18-20 Fr.) con llenado progresivo del balón, máximo 20 cc. Se evaluó la respuesta al tratamiento en función de la presencia de manchado. RESULTADOS: Se incluyeron 7 pacientes (6 varones y 1 mujer) con edad media de 9.7 años (rango, 5-15); dos con antecedente de malformación anorrectal, una enfermedad de Hirschsprung, 1 teratoma sacrococcígeo y 3 encopresis funcionales. Tres pacientes presentaban manchado diario y 4 de forma frecuente. La media de presión basal del canal fue de 32,34 mmHg (rango, 11,74-50,75) con maniobra defecatoria negativa en 2 casos, deficiente en 3 y disinérgica en 2. La media de tiempo realizando el entrenamiento intestinal hasta lograr estar asintomáticos fue 5.14 meses (rango, 2-11), con un seguimiento medio de 16,14 meses (rango, 3-24), manteniéndose limpios actualmente los 7 pacientes. CONCLUSIONES: El presente estudio sugiere que la reeducación de la maniobra defecatoria mediante entrenamiento domiciliario parece ser una terapia eficaz y eficiente, logrando excelentes resultados a medio plazo.

[Relationship between the radiological length of the opaque enema and the aganglionic length of the segment in Hirschsprung's disease]. / Relación entre la longitud radiológica del enema opaco y la longitud agangliónica de la pieza en la enfermedad de Hirschsprung.

INTRODUCTION: Barium enema was the first method used for the diagnosis of Hirschsprung's disease, with the appearance of anorectal manometry and its combination with rectal suction biopsy, barium enema has lost value as a diagnosis method but it has also gain importance to decide the surgical technique that will be used for the correction of the disease. AIM: To determine the correlation between the length of the affected segment showed by barium enema valued and the length of the removed piece. MATERIALS AND METHODS: We have studied all Hirschsprung disease's cases diagnosed and treated in our center since 1998, 127 patients underwent Soave-Boley's technique and 51 De La Torre's descent technique. Routinely preoperative barium enema was performed in all cases and determine the location of the transition zone and compared with the aganglionic segment's length specified by pathologist. RESULTS: At 90% of cases the transition zone could be seen at barium enema, it's most common location was rectosigmoid. After statistically analysis the length measured at radiology tests and the length of the anatomic piece showed a low correlation (kappa index 0.0159), being highest values at rectosigmoid transition and very low values at long affected segments. CONCLUSIONS: Barium enema in Hirschsprung's disease is valuable to decide the best surgical technique in each singular case but not to determine the exact length of affected segments. In case of a aganglionic long-segment suspicion, biopsies may be necessary to determinate preoperative length of affected segments.
