Esencia de menta al 1, 6% como espasmolítico intestinalen la colangiopancreatografía retrógrada endoscópica / 1.6% Peppermint oil solution as intestinal spasmolytic in retrograde endoscopic cholangiopancreatography

Objetivos: La aparición de peristaltismo intestinal puede dificultar la realización de exploraciones o intervenciones mediante colangiopancreatografía retrógrada endoscópica(CPRE). Con el fin de disminuirlo es frecuente la utilización de espasmolíticos sistémicos, pese a los efectos adversos anticolinérgicos que presentan. Se propuso formular una preparación de esencia de menta al 1,6% de uso local para evitar estos efectos adversos. Método: Se formuló la preparación de la esencia de menta al 1,6% según la bibliografía encontrada. La efectividad de la fórmula fue valorada de manera semicualitativa según la disminución del peristaltismo. Resultados: Se ensayaron 2 emulgentes siendo polisorbato el más adecuado. El estudio piloto llevado a cabo en 8 pacientes demostró su efectividad y seguridad en la disminución del peristaltismo intestinal. Conclusiones: La esencia de menta al 1,6% constituye una alternativa efectiva y segura a la utilización de espasmolíticos sistémicos. Se requieren posteriores estudios incluyendo un mayor número de pacientes para establecer su utilidad en la práctica clínica habitual (AU)

Objectives: Intestinal peristalsis can impede explorations and interventions using retrograde endoscopic cholangiopancreatography. Systemic spasmolytics are frequently employed to reduce this phenomenon, in spite of the adverse anti-cholinergic effects they are associated with. We proposed a formula using 1.6% peppermint oil solution with local use in order to avoid these adverse side effects. Method: We formulated a preparation of 1.6% peppermint oil solution in accordance with the medical literature. The effectiveness of the formula was evaluated in a semi-qualitative manneraccording to the reduction in peristalsis. Results: We tested two different emulgents, and polysorbate provided the best results. The pilot study carried out with 8 patients demonstrated its effectiveness and safety in reducing intestinal peristalsis. Conclusions: 1.6% peppermint oil solution constitutes an effective and safe alternative to the use of systemic spasmolytics. More studies are needed with a larger sample size in order to establish its usefulness in normal clinical practice (AU)
