[Endoscopic retrograde cholangiopancreatography in patients aged less than 18 years old: our experience]. / Colangiopancreatografía retrógrada endoscópica en pacientes menores de 18 años: nuestra experiencia.

BACKGROUND: There is scant information on the use of endoscopic retrograde cholangiopancreatography (ERCP) in patients under 18. OBJECTIVE: To analyze our experience in all patients under 18 who underwent ERCP. PATIENTS AND METHODS: We performed a retrospective study of all ERCP conducted in patients under 18 between 1993 and 2006. We analyzed indications, endoscopic and radiologic findings, diagnostic and therapeutic success, and complications. RESULTS: We included 31 patients who underwent 36 ERCP in total. The mean age was 9.89 +/- 5 years old. We used general anesthesia in 58.3% (21 patients), with a mean age of 8 +/- 5 years. The most frequent indications were complications after liver transplantation in 33.3% (12 patients), suspicion of biliary obstruction in 27.7% (10 patients), and pancreatitis in 22.2% (8 patients). We achieved cannulation and repletion in the selected duct in 94.4%. The most frequent pathologic findings were changes in the biliary tract after liver transplantation in 25% (9 patients). The results of ERCP were normal in 10 patients (27.7%). Therapeutic maneuvers were indicated in 17 out of the 34 (50%) examinations considered, achieving therapeutic success in 76.47% (13/17). Complications consisted of hemorrhage after simple sphincterotomy in one patient (2.8%) and mild pancreatitis in two patients (5.6%). CONCLUSIONS: We found ERCP to be a safe procedure with a high diagnostic and therapeutic success rate, and a low rate of early complications.

ANTECEDENTES: Hay una escasa información sobre el empleode la colangiopancreatografía retrógrada endoscópica(CPRE) en pacientes menores de 18 años.OBJETIVO: Analizar nuestra experiencia en todos los pacientesmenores de 18 años sometidos a CPRE.PACIENTES Y MÉTODOS: Estudio retrospectivo de todas lasCPRE realizadas a pacientes menores de 18 años entre 1993y 2006. Se analizaron las indicaciones, hallazgos endoscópicosy radiológicos, el éxito diagnóstico y terapéutico, y lascomplicaciones.RESULTADOS: Se incluyeron 31 pacientes a los que se realizaron36 exploraciones en total. La edad media fue de 9,89 ± 5años. Se utilizó la anestesia general en un 58,3% de los pacientes(n = 21), con una edad de 8 ± 5 años. Las indicacionesmás frecuentes fueron, por este orden, las complicacionespostrasplante hepático (12 casos; 33,3%), la sospecha de obstrucciónbiliar (10 casos; 27,77%) y la evaluación de pancreatitis(8 casos; 22,2%). Se logró la canulación y la replecióndel conducto deseado en un 94,4% de los casos. Los hallazgospatológicos más frecuentes fueron las alteraciones en la víabiliar postrasplante hepático (9 casos; 25%). La exploraciónfue compatible con la normalidad en 10 casos (27,7%). Se indicaronmaniobras terapéuticas en 17 de las 34 exploracionesconsideradas como éxito diagnóstico (50%), lográndose eléxito terapéutico en 13 de ellas (76,4%). Las complicacionesregistradas fueron un caso de hemorragia leve postesfinterotomía(2,8%) y 2 pancreatitis leves (5,6%).CONCLUSIONES: La realización de CPRE en nuestra serie hasido segura, con un alto índice de éxito diagnóstico y terapéutico,y pocas complicaciones precoces
