ABSTRACT

Background:

Barrett’s esophagus (BE) is the main risk factor for esophageal adenocarcinoma. Its therapeutic approach is controversial and surgical treatment in the presence of high-grade intraepithelial neoplasia may be indicated. Endoscopic approach is an alternative with lower mortality and morbidity rates and favorable results.

Objective:

To define the best option, according to literature, to treat Barrett’s Esophagus. Materials and

methods:

Design:

Systematic review of PUBMED, EMBASE, LILACS, and Cochrane Library databases was conducted and articles of randomized, controlled studies on BE endoscopic ablative treatment were selected. The systematic review through PUBMED retrieved results with higher evidence level and available recommendation grade regarding BE ablative therapy. Nine articles on randomized, controlled studies classified as A or B according to the Oxford table were selected. Cryotherapy, laser, photodynamic therapy (PDT), multipolar electrocoagulation (MPEC), and ablation through argon plasma coagulation (APC) and radiofrequency were considered ablation therapies. Patients 649 patients from 10 different studies were analysed.

Results:

PDT was found to present an increase in treatment failure compared with APC, NNH = -7. BE ablation through MPEC or APC was found to have similar risk for treatment failure in meta-analysis. PDT associated with proton pump inhibitor (PPI) is beneficial for BE ablation regarding PPI use alone, NNT = 2. Radiofrequency with PPI is an efficient method to reduce risk of treatment failure, NNT = 1.

Conclusions:

There are no studies demonstrating the benefit of indicating cryotherapy or laser therapy for BE endoscopic approach. APC ablation was found to have superior efficacy compared with PDT and ablation through APC and MPEC was found to present effective, similar results. Radiofrequency is the most recent approach requiring comparative studies for indication.
RESUMEN

Introducción:

El esófago e Barrett (BE) es un factor de riesgo importante para adenocarcinoma de esófago.Su manejo terapéutico es controversial y el tratamiento quirúrgico en la presencia de neoplasia intraepitelial de alto grado puede estar indicado. El manejo endoscópico es una alternative con menores tasas de morbilidad y mortalidad y con resultados favorables.

Objetivo:

Definir la major opción de tratamiento del esófago de Barrett de acuerdo a la literatura. Materiales y

métodos:

Diseño:

Se realize una revisión sistemática de PUBMED, EMBASE, LILACS yla librería Cochrane y los artículos randomizados, controlados en ablación endoscópica de BE fueron seleccionados. Esta revisión de PUBMED mostró resultados de una evidencia muy alta y recomendación alta para el uso de terapia ablativa. Nueve artículos de studios randomizados y controlados fueron catalogados grado A o B de aacuerdo a la table de Oxford y fueron seleccionados.Fueron consideradas como terapia ablativa, la crioterapia, laser,terapia fotodinámica (PDT),electrocoagulación multipolar (MPEC) ,ablación con coagulación por argón plasma (APC) y radiofrecuencia. Pacientes 649 pacientes de 10 estudios diferentes fueron analizados.

Resultados:

El PDT se halló que tenía mas fallas que el APC , NNH=-7. La ablación del esófago de barrett por MPEC o APC tuvieron el mismo riesgo de fracaso terapéutico en los meta-análisis.La PDT asociado al uso de Inhibidores de bomba de protones (PPI) es beneficiosa versus el uso de, los PPI solos, NNT=2. La radiofrecuencia con PPI es un método eficiente para reducer el riesgo de fracas terapéutico, NNT=1.

Conclusiones:

No hay studios que demuestren el beneficio de la crioterapia o la terapia con laser para el esófago de Barrett, se encontró que tiene una eficacia superior comparada con el PDT y la ablación por APC y MPEC tenían resultados efectivos y similares.La radiofrecuencia es el manejo más reciente y requiere estudios comparativos para su indicación.
