[Effect of the administration of rectal indomethacin on amylase serum levels after endoscopic retrograde cholangiopancreatography, and its impact on the development of secondary pancreatitis episodes]. / Efecto de la administración de indometacina rectal sobre los niveles séricos de amilasa posteriores a colangiopancreatografía retrógrada endoscópica y su impacto en la aparición de episodios de pancreatitis secundaria.

BACKGROUND: Hyperamylasemia and acute pancreatitis represent the most frequent major complication after endoscopic retrograde cholangiopancreatography (ERCP), developing in 1-30% of cases. OBJECTIVE: To determine the incidence of hyperamylasemia and acute pancreatitis after ERCP, and to assess the utility of rectal indomethacin to prevent these events. MATERIAL AND METHODS: A randomized clinical trial. During a 12-month period 150 patients were included. They were divided up into a study group (n = 75), where 100 mg of rectal indomethacin were administered 2 hours prior to the procedure, and a control group (n = 75), which received rectal glycerin. Two hours after ERCP serum amylase levels were measured and classified as follows: 0or=600 IU/L. Clinical pancreatitis episodes were quantified and classified according to Ranson's criteria. RESULTS: Gender distribution: 100 women and 50 men. Mean age: 55.37 +/- 18.0 for the study group, and 51.1 +/- 17.0 for the control group. A diagnosis of benign pathology was present in 56 (74.7%) cases in the study group, and 59 (78.7%) controls. After ERCP 13 (17.3%) patients in the study group and 28 (37.3%) in the control group developed hyperamylasemia (p (2) 0.05). Hyperamylasemia > 600 IU/L was found in 3 patients in the study group, and in 10 in the control group (p = 0.001). Mild pancreatitis was detected in 4 (5.3%) patients in the study group, and in 12 (16%) patients in the control group (p = 0.034). There were no deaths or adverse drug reactions. CONCLUSIONS: Rectal indomethacin before ERCP decreases the risk of hyperamylasemia and pancreatitis. Indomethacine is a feasible, low-cost drug with minimal or nil side effects.

Introducción: hiperamilasemia y pancreatitis aguda representan las complicaciones mayores más frecuentes posteriores a colangiopancreatografía retrógrada endoscópica (CPRE), apareciendo en 1-30% de los casos. Objetivo: determinar la incidencia de hiperamilasemia y pancreatitis posterior a CPRE y evaluar la utilidad de indometacina rectal para la prevención de estos. Material y métodos: ensayo clínico controlado. Durante un periodo de 12 meses se incluyeron 150 pacientes. Estos fueron divididos en grupo de estudio (n = 75), a quienes se administró indometacina rectal 100 mg 2 horas previas al procedimiento, y control (n = 75) que recibió glicerina. Dos horas posteriores a la CPRE se determinó el nivel de amilasa sérica y se clasificaron en: 0 = 600 UI/l. Los episodios de pancreatitis clínica se cuantificaron y clasificaron de acuerdo a los criterios de Ranson. Resultados: distribución por género: 100 mujeres y 50 hombres. Edad media: 55,37 ± 18,0 para el grupo de estudio y 51,1 ± 17,0 para el control. El diagnóstico de patología benigna se presentó en 56 (74,7%) casos del grupo de estudio y 59 (78,7%) del control. Posterior al procedimiento, 13 (17,3%) pacientes del grupo experimental y 28 (37,3%) del control desarrollaron hiperamilasemia (p 600 UI/l en 3 pacientes del grupo de estudio y 10 del control (p = 0,001). Se detectó pancreatitis leve en 5,3% de los pacientes del grupo de estudio y 16% del control (p < 0,05). No hubo mortalidad ni eventos adversos. Conclusiones: indometacina rectal previo a CPRE disminuye el riesgo de hiperamilasemia y pancreatitis. La indometacina es accesible, de bajo costo con mínimos o nulos efectos secundarios
