Abstract

Background: Aluminum potassium sulfate and tannic acid sclerotherapy for hemorrhoids produced almost the same effects as excisional hemorrhoidectomy. However, its long-term effectiveness remains unknown.

Objective: The purpose of this study was to investigate the long-term results of sclerotherapy using aluminum potassium sulfate and tannic acid for treating prolapsed hemorrhoids.

Design: This was a retrospective review of a single-institution experience.

Settings: This study was conducted within a coloproctology unit at a community-based hospital.

Patients: In total, 1180 patients with grade II to IV hemorrhoids treated with injection sclerotherapy were enrolled.

Main outcome measures: Efficacy measures included cumulative recurrence rates and postoperative complications.

Results: Recurrence rates at 3, 6, and 9 years were 7.4%, 27.2%, and 47.5%. Postoperative complications included fever ≥38°C in 16 (1.4%) patients, rectal ulcer in 10 (0.9%) patients, rectal stricture in 5 (0.4%) patients, and perianal abscess in 4 (0.3%) patients.

Limitations: This was a retrospective, nonrandomized, single-center study. In addition, office visits after 3 years were optional and the number of follow-ups steadily decreased.

Conclusions: Sclerotherapy using aluminum potassium sulfate and tannic acid offers reasonable long-term results and is associated with low complication rates. Therefore, it seems to be an attractive alternative for patients with prolapsed hemorrhoids.

Antecedentes: La escleroterapia con sulfato de aluminio y potasio, y ácido tánico para las hemorroides produjo casi los mismos efectos que la hemorroidectomía por escisión. Sin embargo, se desconoce su eficacia a largo plazo.

Objetivo: El propósito de este estudio fue investigar los resultados a largo plazo de la escleroterapia con sulfato de aluminio y potasio, y ácido tánico para tratar las hemorroides prolapsadas.

Diseo: Revisión retrospectiva de la experiencia de una sola institución.

Entorno clinico: Este estudio se realizó dentro de una unidad de coloproctología en un hospital comunitario.

Pacientes: En total, 1.180 pacientes fueron inscritos con hemorroides grado II a IV tratados con inyecciones esclerosantes.

Principales medidas de valoracion: Las medidas de eficacia incluyeron tasas acumulativas de recurrencia y complicaciones posoperatorias.

Resultados: La tasa de recurrencia a los 3, 6 y 9 años fue del 7,4%, 27,2% y 47,5%, respectivamente. Las complicaciones posoperatorias incluyeron fiebre ≥ 38 grados Celsius en 16 pacientes (1,4%), úlcera rectal en 10 (0,9%), estenosis rectal en 5 (0,4%) y absceso perianal en 4 (0,3%) pacientes.

Limitaciones: Este fue un estudio retrospectivo, no aleatorio, de un solo centro. Adicionalmente, las visitas al consultorio después de 3 años eran opcionales y el número de seguimientos disminuyó constantemente.

Conclusiones: La escleroterapia con sulfato de aluminio y potasio, y ácido tánico ofrece resultados razonables a largo plazo y está asociada con bajas tasas de complicaciones. Por tanto, parece ser una alternativa atractiva para pacientes con hemorroides prolapsadas. Consulte Video Resumen en http://links.lww.com/DCR/B733. (Traducción- Dr. Francisco M. Abarca-Rendon).
