Description
Summary:Aim: the aim of this study was to assess the effectiveness of topical glyceryl trinitrate (GTN) in the treatment of anal fissure. Patients: eighty consecutive patients were randomized to receive 0.2% GTN gel twice a day during a minimum of 6 weeks. Of these 80 patients 34 were males and 46 female, with ages be-tween 20 and 78 years. All patients underwent a work-up that included gender, age, symptom duration, site, previous treatment attempts, pain score, associated diseases, and maximum anal resting pressure. These patients were followed at regular intervals of 4, 8, and 12 weeks to assess symptom outcome, rate of healing, adverse effects, and recurrence rate. Results: pain scores were significantly reduced during the treatment period in 65% of cases. After 4 weeks, 55% of patients had healed, and 78% after 9 weeks. In 18 patients (22%), anal fissures did not heal even with 6 additional weeks of treatment, and 12 of them (15%) underwent lateral sphincterotomy. Sixty one percent of patients had flushing and 15% severe headaches. Conclusion: the results of this study have demonstrated the significant benefit of topical GTN when administered to patients suffering from anal fissures.<br>Objetivo: el objetivo de este estudio era la valoración de la aplicación tópica de gliceril trinitrato en el tratamiento de las fisuras anales. Pacientes: un total de 80 consecutivos pacientes eran randomizados recibiendo gliceril trinitrato al 0,2% gel dos veces al día, durante un mínimo de 6 semanas. De los 80 pacientes, 34 eran varones y 46 mujeres, con edad comprendida entre 20 y 78 años. En los pacientes se controlaba sexo, edad, duración de síntomas, duración de tratamiento, localización, patología previa asociada, y valoración del dolor. Seguimiento a 4, 8 y 12 semanas, para controlar la sintomatología, el grado de curación, los efectos adversos y la relación de recidiva. Resultados: la disminución del dolor fue significativa en el 65% de los casos y se consiguió la curación de la fisura a las 4 semanas en el 55% de los pacientes, y el 78% a las 9 semanas de tratamiento. El tratamiento falló en 18 (22%) casos, requiriendo intervención quirúrgica en 12 (15%) de ellos. Un 61% de los pacientes refirieron cefalea leve y rubicundez facial tras la aplicación de GTN, y en 12 (15%) pacientes la cefalea era intensa. Conclusión: estos resultados han demostrado el significativo beneficio de la aplicación tópica de gliceril trinitrato al 0,2% en las fisuras anales.
