Abstract
Introduction

Zenker's diverticulum (ZD) is a protrusion of the hypopharyngeal mucosa with a prevalence of 2/100,000 inhabitants. The symptoms of the patients determine the need for treatment, which can be surgical or endoscopic. The latter, known as endoscopic septotomy or diverticulotomy (ED), this involves dissecting the diverticular septum, which can be performed with different dissection devices.

Aim

The aim of our study was to evaluate the efficacy and safety of ED with Stag-Beetle Knife device, as well as to conduct a literature review to assess the position of the technique in the current scientific panorama.

Material and methods

Descriptive retrospective study that includes patients who underwent ED with SB-Knife between June 2017 and February 2020. Literature review of the available evidence between January 2013 and April 2020 of ED with SB-Knife technique and its variants.

Results

Twelve patients (66% male) with a median age of 70.5 years were collected. The median size of diverticular was 32.5 mm and complete remission was observed in 75% of the cases. Fourteen interventions were performed with a technical success of 92.8%. There were no serious complications. A literature review was carried out, finding 13 papers, of which 8 were finally included (6 retrospective studies, a series of cases and a clinical case).

Conclusion

Based on our experience and the reviewed literature, we consider ED with SB-Knife is a safe, effective and reproducible technique, and may be a better alternative to surgery in patients with ZD.

Resumen
Introducción

El divertículo de Zenker (DZ) es una protrusión de la mucosa hipofaríngea con una prevalencia de 2/100.000 habitantes. La clínica condiciona la necesidad de tratamiento, pudiendo ser quirúrgico o endoscópico. Este último, denominado septotomía o diverticulotomía endoscópica (DE), consiste en la disección del septo diverticular, pudiendo realizarse con distintos dispositivos disectores.

Objetivo

El objetivo del estudio es evaluar la eficacia y seguridad de la DE mediante el dispositivo Stag-Beetle Knife, así como realizar una revisión de la literatura para valorar el posicionamiento de la técnica en el panorama científico actual.

Material y métodos

Estudio retrospectivo descriptivo que incluye pacientes intervenidos mediante DE con SB-Knife entre junio de 2017 y febrero de 2020. Revisión de la literatura de la evidencia disponible entre enero de 2013 y abril 2020 de la DE mediante la técnica con SB-Knife y sus variantes.

Resultados

Se recopilaron 12 pacientes (66% hombres) con una mediana de 70,5 años. El tamaño diverticular fue de 32,5 mm de mediana y la remisión completa se objetivó en el 75% de los casos. Se realizaron 14 intervenciones con un éxito técnico de 92,8%. No se produjeron complicaciones graves. Se realizó una revisión de la literatura encontrando 13 trabajos de los cuales se incluyeron finalmente 8 (seis estudios retrospectivos, una serie de casos y un caso clínico).

Conclusiones

En base a nuestra experiencia y a la bibliografía revisada, consideramos que la DE mediante SB-Knife es una técnica segura, eficaz y reproducible, pudiendo ser una mejor alternativa a la cirugía en pacientes con DZ.
