Tratamiento endoscópico del divertículo de Zenker / Endoscopic management of Zenker's diverticulum

Introducción: el divertículo de Zenker es un saco que se produce como resultado del aumento de presión a nivel de la pared posterior de la hipofaringe que lleva a la protrusión de mucosa y submucosa a través de los músculos constrictor inferior de la faringe y cricofaríngeo. Discusión: es característico de los pacientes adultos mayores en la séptima y octava década de la vida, con una discreta predilección por el sexo masculino. El síntoma principal es la disfagia y en casos severos episodios de broncoaspiración. Tiene diferentes opciones de tratamiento, entre las que se encuentran el abordaje quirúrgico y endoscópico, siendo esta última la técnica más recomendada dado sus buenos resultados y menores tasas de complicaciones descritas.

Introduction: Zenker ́s diverticulum is a saccular formation in the posterior wall of the hypopharynx due to increased pressure, leading to mucosal and sub-mucosal herniation between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle. Discussion: it is primarily seen in elderly individuals in the seventh and eighth decades of life, with a discrete higher predominance in men. Dysphagia is the main symptom and episodes of pulmonary aspiration may present in severe cases. There are several treatment options, among which is endoscopic surgical approach. The latter constitutes the most recommended technique for it has shown good results and lower complication rates.

Zenker Diverticulum: Does Size Correlate with Preoperative Symptoms?

Abstract Introduction Zenker diverticulum (ZD) usually affects adults after the 7th decade of life. Treatment for ZD is indicated for all symptomatic patients, but some patients prefer to defer surgical treatment until symptoms get worse and decrease their quality of life. Objective To evaluate the association of the preoperative symptoms in ZD patients with the size of the ZD. Methods A retrospective study design. Electronic medical records were used to identify patients diagnosed with ZD and treated over 11 years. Data collection included the chief complaints and symptoms, medical history, and findings on radiologic swallow evaluations of the patients. The diverticulum size was stratified into 3 groups: small (< 1 cm), moderate (1-3 cm), and large (> 3 cm). Results A total of 165 patients were enrolled and stratified by diverticulum size (48 small, 67 medium, and 50 large). Dysphagia, cough, and regurgitation were the most prevalent symptoms. Dysphonia was more frequent among patients with a small pouch. Logistic regression analysis showed that dysphagia and choking were associated with large and medium diverticulum size (p < 0.05). Additionally, dysphonia was significantly associated with the presence of a small-sized ZD (p < 0.04). Conclusion Upper gastrointestinal symptoms such as dysphagia and choking may be associated with a ZD > 1 cm and should always be evaluated. Additionally, the presence of dysphonia was found to be correlated with a ZD < 1 cm, suggesting that a prompt and appropriate fluoroscopic evaluation must be considered in those patients in whom no other clear cause of dysphonia is evident.

Caso clínico-radiológico: divertículo de Zenker / Clinical-radiological case: Zenker's diverticulum

Zenker's diverticulum develops in the hypopharynx, usually between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle, at the level of the C5 and C6 vertebrae. It often manifests clinically with dysphagia, persistent reflux, and halitosis. Its reference diagnosis is through barium video swallowing observed by fluoroscopy. Management is surgical with a cervical or transoral approach, the latter having a better safety profile

Preescolar con divertículo de Zenker y hallazgo intraoperatorio de cuerpo extraño esofágico / Preschool-age child with Zenker's diverticulum and intraoperative finding of an esophageal foreign body

Introducción. El divertículo de Zenker es una evaginación sacular ciega que puede presentarse a nivel faringoesofágico. No se conoce exactamente su incidencia en la edad pediátrica, constituyendo una patología muy infrecuente. La sintomatología es inespecífica, lo que dificulta el diagnóstico precoz y determina un mayor riesgo de complicaciones asociadas. Caso clínico. Paciente preescolar femenina con cuadro recurrente de emesis con deshidratación, posteriormente asociado a disfagia, a quien se le diagnosticó un divertículo de Zenker. Se realizó tratamiento quirúrgico con hallazgo intraoperatorio de dilatación esofágica, un área de estenosis secundaria al hallazgo incidental de un cuerpo extraño y divertículo de Zenker en la región lateral del esófago dilatado. Discusión. Esta patología es extremadamente rara, pero se debe tener en cuenta dentro de los diagnósticos diferenciales en pacientes con sintomatología faringo-esofágica. Conclusión. Se presenta una preescolar sin antecedente de procedimientos esofágicos o malformaciones congénitas asociadas con diagnóstico de un divertículo de Zenker y dilatación esofágica por un cuerpo extraño, tratada quirúrgicamente de forma exitosa.

Introduction. Zenker's diverticulum is a blind saccular evagination that can present at the pharyngoesophageal level. Its incidence in pediatric age is not exactly known, constituting a very infrequent pathology. The symptoms are nonspecific, which makes early diagnosis difficult and determines a higher risk of associated complications.Clinical case. Female preschool patient with recurrent dehydration due to emesis, later associated with dysphagia, who was diagnosed with Zenker's diverticulum. Surgical treatment was performed with intraoperative finding of esophageal dilation, an area of stenosis secondary to the incidental finding of a foreign body, and a Zenker's diverticulum in the lateral region of the dilated esophagus. Discussion. This pathology is extremely rare, but it should be taken into account within the differential diagnoses in patients with pharyngo-esophageal symptoms. Conclusion: We present a preschool female patient with no history of esophageal procedures or congenital malformations associated with a diagnosis of Zenker's diverticulum and esophageal dilation due to a foreign body, successfully treated surgically.

Divertículo de Zenker: manejo endoscópico con o sin diverticulotomo / Zenker's diverticulum: endoscopic treatment with or without diverticulotome

Resumen El divertículo de Zenker se define como un divertículo localizado en la pared esofágica posterior que tiene como cuello proximal al músculo cricofaríngeo. La mayoría de los pacientes presenta síntomas después de los 60 años de edad. Antes el manejo estándar se realizaba la diverticulotomía quirúrgica, pero desde hace más de 20 años se introdujo el manejo endoscópico. Desde hace más de 15 años se introdujo un diverticulotomo que facilita la realización del procedimiento, pero su uso no se ha instaurado ampliamente en Colombia. Por ello, el objetivo de este estudio es evaluar si la diverticulotomía endoscópica con el uso de este dispositivo es más fácil (rápida) que el método estándar. Materiales y métodos: se realizó un estudio prospectivo evaluando dos métodos endoscópicos para tratar el divertículo de Zenker, con el objetivo principal de conocer en cuál de ellos el tiempo de incisión del tabique era menor. El tiempo del procedimiento se contaba después de la colocación de la sonda en el método estándar o después de colocar el diverticulotomo en posición (método con diverticulotomo), ya que es el momento exacto en el cual se inicia el corte del tabique y se contabilizaba el tiempo (registro en video) cuando este corte terminaba. Resultados: de enero de 2015 a diciembre de 2018 en total se incluyeron 20 pacientes. El diagnóstico de Zenker fue realizado por una endoscopia y esofagograma para clasificar el tamaño del mismo. El promedio de edad de los pacientes fue de 61 años (46-85). En cada uno de los grupos se asignaron 10 pacientes. En 7 pacientes del grupo método estándar se resolvieron los síntomas, en comparación con 9 del grupo del método con diverticulotomo. Los tres pacientes que no respondieron presentaron en el seguimiento a 18 meses un estadio II de la escala de deglución de resultados funcionales. El tiempo promedio del procedimiento fue de 32 (25-45) minutos en el grupo del método estándar y 12 (7-15) minutos en el grupo de método con diverticulotomo (p < 0,001). Conclusiones: La miotomía del divertículo de Zenker con el uso de endoscopia flexible utilizando el diverticulotomo tiene beneficios potenciales en términos de tiempos operatorios más cortos, estancias posoperatorias más cortas y un inicio más temprano de la dieta. Desde el punto de vista técnico, permite una mejor exposición del tabique, lo que facilita su corte, pero se necesitan estudios más grandes para confirmar estos resultados.

Abstract Zenker's diverticulum is defined as a diverticulum located in the posterior esophageal wall, just above the cricopharyngeal muscle. Most patients experience symptoms in this area after the age of 60. In the past, the standard treatment was surgical diverticulotomy, but endoscopic treatment was introduced over 20 years ago. For more than 15 years, overtubes are introduced to facilitate the procedure, but their use is not been widely established in our country. Therefore, this study aims to evaluate whether endoscopic diverticulotomy with the use of this device is easier (faster) than the standard method. Materials and methods: A prospective study was conducted to establish which of the two endoscopic methods to treat Zenker's diverticulum (ZD) made the septum incision time shorter. The time count was done using video recording and started when the probe -standard method (SM)- or the overtube (MD) were placed, as this is the exact moment when septum cutting begins. The count stopped when the cut was finalized. Results: A total of 20 patients were treated from January 2015 to December 2018. Zenker's diverticulum diagnosis was achieved by endoscopy and esophagogram to classify the size of the tumor. The average age of the patients was 61 years (46-85). Ten patients were assigned to each group. Symptoms resolved in 7 patients of the SM group, compared to 9 in the MD group. The three patients who did not respond to the treatment were classified as stage II in the functional outcome swallowing scale at 18 months of follow-up. The average time of the procedure was 32 (25-45) minutes in the SM group and 12 (7-15) minutes in the MD group (p <0.001). Conclusions: ZD myotomy with flexible endoscopy using an overtube has potential benefits in terms of shorter operative times, shorter post-operative stays, and an earlier reintroduction of food. From a technical point of view, this method allows for better exposure of the septum, which facilitates cutting. However, more extensive studies are needed to confirm these results.

The Esophageal Diverticulum: About Two Cases

The hypopharyngeal diverticulum of the cervical esophagus, also knows as Zenker's diverticulum, is the most common esophageal diverticulum. It develops at the junction of the hypopharynx and the esophagus. Themost present symptom is dysphagia. Between the period of 01/01/2018 to 31/12/2018, we accessed two patients with esophageal diverticulum.both underwent surgical treatment -diverticulectomy at department of the visceral surgery II of the Military HospitalMohamed V of Rabat.Morocco.The aim of this report is to evaluate the diagnostic methods and the surgical outcomes by comparing them to others technics used in the treatment of the esophageal diverticulum

A Case of Zenker's Diverticulum Mimicking a Right Side Thyroid Nodule

Zenker's diverticulum, a pulsion diverticulum of the hypopharynx, is a rare lesion that commonly occurs in left side of hypopharynx. The incidence of esophageal diverticula is much lower than that of focal lesions or nodules of thyroid. In an ultrasonography, the outpouching just like a focal thyroid lesion, may present as an oval or circular structure. The food remnants or gas bubbles present in the diverticulum may mimic microcalcifications presented in papillary thyroid carcinoma. We reported a case of right side Zenker's diverticulum mimicking a thyroid cancer in thyroid ultrasonography.

Uso seguro y eficaz del IT-Knife-2 en el manejo endoscópico del divertículo de Zenker (DZ) / Efficacy and safety of the endoscopic management of Zenker diverticulum with IT-Knife 2 device

Objetivo: Evaluar la eficacia y seguridad del manejo endoscópico del DZ con IT-knife 2. Materiales y métodos: Estudio prospectivo, multicéntrico (Hospital Nacional Edgardo Rebagliati Martins y la Clínica El Golf). Se incluyeron todos los pacientes con DZ sintomáticos desde setiembre 2013 a agosto 2016, los cuales fueron sometidos a miotomía cricofaringea endoscópica. Técnica: se afrontó el septo del DZ con un cap y luego se seccionó con el IT-Knife 2 (ENDOCUT Q Efecto 3-2-5) hasta su base. Se comparó la escala de disfagia antes y después del procedimiento, al 1er mes y luego de los 3 meses. Resultados: Se incluyeron 20 pacientes (11 varones; edad promedio: 71 años). El tamaño promedio del DZ fue de 40,5 mm. El tiempo promedio de la miotomía cricofaringea fue de 13,75 minutos. El éxito clínico fue del 100%, presentando un descenso estadísticamente significativo (p<0,001) en el score de disfagia de 2+/-0,86 pre-tratamiento a 0,05+/-0,22 al primer mes post- tratamiento. La recurrencia clínica a partir del tercer mes fue de 15%, resolviendo por completo con un segundo tratamiento endoscópico. No se presentó ningún caso de perforación ni sangrado. Dos pacientes cursaron con neumonía. Conclusión: El tratamiento endoscópico del DZ mediante el uso del IT-knife 2 es altamente eficaz y seguro, y de menor complejidad que la experiencia previa

Objective: To evaluate the efficacy and safety of the endoscopic management of Zenker Diverticulum with IT-Knife 2 device. Materials and methods: prospective and multicenter study (Edgardo Rebagliati Martins National Hospital and Golf Clinic). We included all patients with sintomatic Zenker Diverticulum that were treated with endoscopic cricopharyngeal miotomy from september 2013 until august 2016. Technique: the diverticulum septum was faced with a cap, and then it was cut by the IT-Knife 2 (ENDOCUT Q, effect 3-2-5) until its baseline. Disphagia score was compared before and 1 and 3 months after the procedure. Results: 20 patients were included (11 men; average age: 71 years). The median size of Zenker Diverticulum was 40.5 mm. The median duration of the cricopharyngeal miotomy was 13.75 minutes. Clinical success was 100%. There was a significative decrease (p<0.001) in the disphagia score from 2+/-0.86 before the procedure to 0.05+/-0.22 one month after it. Recurrence after 3 months was 15% and it was completely solved after a second endoscopic treatment. Niether perforation nor bleeding was reported. Two patients had pneumonia. Conclusion: the endoscopic management of Zenker Diverticulum with IT-Knife 2 is highly effective, safe and less complex than previous technique experience

Septotomía endoscópica del divertículo de Zenker / Endoscopy septotomy in zenker diverticulum

Introducción: La Diverticulotomía o Septotomía endoscópica en el divertículo de Zenker, es una alternativa a otros abordajes terapéuticos. El presente estudio muestra nuestra experiencia de esta técnica endoscópica. Pacientes y Métodos: Análisis retrospectivo, entre el 2009 y 2017 en pacientes con divertículo de Zenker. La septotomía se realizó utilizando videoendoscopio flexible, esfinterótomo aguja, electrobisturi para DSE tipo Hibridknife, mediante una técnica ya estandarizada. Resultados: Se trataron 25 pacientes con edad promedio de 71 años (rango etario de 45 a 84 años). En una paciente su mejoría fue muy poca, por lo que se sometió a intervención quirúrgica, donde tampoco hubo resultados consistentes. Veintiún pacientes mostraron un alivio completo de la disfagia. Tres pacientes que tuvieron recurrencia sintomática fueron tratados con el mismo método endoscópico entre 2 y 4 sesiones evolucionando de forma satisfactoria. Conclusiones: La septotomía endoscópica del divertículo de Zenker es un método eficaz y seguro, por lo tanto representa una alternativa real a la cirugía.

Introduction: Diverticulotomy or Endoscopic septotomy in Zenker's diverticulum is an alternative to others therapeutics approaches. The present study shows our experience of this endoscopic technique. Patients and methods: Retrospective analysis between 2009 and 2017 in patients with Zenker's diverticulum. The procedure was performed using a flexible video endoscope and a needle knife, Erbe hybrid knife probe, using an already standardized technique. Results: Twenty-five patients with an average age of 71 years (age range 45-84 years) were treated. In one patient his improvement was very little, therefore surgical procedure was performed, nevertheless this procedure had not consistent results. Twenty-one patients showed complete relief of dysphagia. Three patients who had symptomatically relapsed were retreated with the same endoscopic method between 2 and 4 sessions with good results. Conclusions: Zenker's endoscopic septotomy of the diverticulum is an effective and safe method; thereby it represents a real alternative to surgical treatment.

The application of dynamic high-frequency ultrasound in the diagnosis of Zenker diverticulum / 中国医学装备

Objective:To explore the diagnostic value of high-frequency ultrasound for Zenker diverticulum.Methods: 15 patients who were suspected as Zenker diverticulum through the diagnosis of using high frequency ultrasound were analyzed in the research. Their appearances of ultrasound were summarized, and these results were compared with barium meal at upper gastrointestinal tract and results of postoperative pathology, respectively.Results: In 15 patients, 4 cases were confirmed by adopting barium meal at upper gastrointestinal tract, and 11 cases were confirmed by adopting postoperative pathology. All of lesions in 15 cases were located on the back of left side of the thyroid gland, and there were 3 kinds of sonographic appearance. The first kind was equal echo lesion, and there were spots and schistoses without echo inside lesion, their form showed a semicircle shape. The second kind was hypoechoic, the form showed irregularity or semi cyclic annular, and the border was clear, and there were strong echogenic spots. The third kind was hyperechoic lesions, and the strong echo were movable with morphological changing after the slight pressure of search unit, and slim half ring low echo wall can be seen indistinctly around lesions.Conclusion:High-frequency ultrasonography is a convenient, rapid and non-invasive method for the diagnosis of Zenker diverticulum, and it is helpful to grasp its ultrasonogram characteristic and examination method in early detection of disease, avoiding misdiagnosis and missed diagnosis. Therefore, it has important clinical value.

Tratamiento actual para el divertículo de Zenker / Current treatment of Zenker´s diverticulum

Introducción: la cirugía es el tratamiento de elección para los divertículos de Zenker, pero existen diferencias en relación con el acceso a utilizar: abierto o endoscópico. Objetivo: comparar los resultados del tratamiento quirúrico del divertículo de Zenker de acuerdo con el acceso utilizado. Métodos: se realizó una revisión bibliográfica en PubMed/Medline con las palabras: divertículo, Zenker, faringoesofágico, cricofaríngeo, diverticulectomía, diverticulopexia, diverticulotomía, diverticulostomía publicados entre 2006 y 2016. Se incluyeron estudios con más de 40 casos, comparativos o no, en los idiomas inglés, español, portugués, francés e italiano. Las variables estudiadas fueron: indicaciones quirúrgicas, recidiva del divertículo, tiempo quirúrgico, tiempo para la alimentación oral, estadía hospitalaria, reoperaciones, complicaciones, mejoría de los síntomas y mortalidad. Resultados: no se encontraron ensayos aleatrorizados. Se incluyeron cuatro revisiones sistemáticas y un metanálisis, además de un grupo de estudios que comparan los accesos peroral y transcervical y otros que comparan los resultados entre diferentes técnicas de los accesos endoscópico y convencional. La mayoría de los estudios son de carácter retrospectivo.Para evaluar los resultados a largo plazo se tomaron los artículos con seguimiento mayor de 12 meses. Conclusiones: con el acceso abierto se logran mejores resultados a largo plazo, pero tiene más complicaciones inmediatas. Es preferible usarlo en pacientes jóvenes y cuando existen condiciones anatómicas desfavorables para la endoscopia. El tratamiento endoscópico constituye una opción adecuada para pacientes de alto riesgo quirúrgico y anestésico(AU)

Introduction: Surgery is the treatment of choice in Zenker´s diverticula, but there are different opinions about the access to be used, that is, open or endoscopic. Objective: To compare the results of the surgical treatment results of Zenker´s diverticulum according to the access employed. Methods: A literature review was made in PubMed/Medline using the keywords: diverticulum, Zenker, pharyngoesophageal, crycopharyngeal, diverticulectomy, diverticulopexy, diverticulotomy, diverticulostomy in articles published from 2006 to 2016. There were included several studies of more than 40 cases, either comparative or not in English, Spanish, French, Italian and Portuguese languages. The studied variables were surgical indications, recurrence, surgical time, length of time for oral feeding, hospital stay, reoperations, complications, symptoms improvement and mortality. Results: Randomized studies were not found. Four systematic reviews, one meta-analysis, comparative studies on perioral and transcervical access and others which compare the results of the endoscopic and of the conventional access were all included. Most of them were retrospective. For evaluation of long-term results, those articles with follow-up periods over 12 months were taken. Conclusions: The open access provides better long-term results, but it has more immediate complications. It is advisable to use it in young patients and when anatomic conditions are unfavorable for the endoscopic treatment. Finally, the endoscopic treatment is an adequate choice for patients with high surgical and anesthetic risk(AU)

Acquired Pharyngeal Diverticulum after Anterior Cervical Fusion Operation Misdiagnosed as Typical Zenker Diverticulum

A pharyngeal diverticulum is a rare complication of an anterior cervical discectomy and fusion (ACDF). We present a case of a pharyngeal diverticulum after an ACDF, which was misdiagnosed as a typical Zenker diverticulum. A 54-year-old woman presented with dysphagia and a sense of irritation in the neck following C5 through C7 cervical fusion 3 years prior. The patient underwent open surgery to resect the diverticulum with concurrent cricopharyngeal myotomy. An ACDF-related diverticulum is difficult to distinguish from a typical Zenker diverticulum.

ASSESSMENT OF MECHANICAL AND MANUAL SUTURE IN THE SURGICAL TREATMENT OF THE PHARYNGOESOPHAGEAL DIVERTICULUM / AVALIAÇÃO DA SUTURA MECÂNICA E MANUAL NO TRATAMENTO CIRÚRGICO DO DIVERTÍCULO FARINGOESOFÁGICO

Background: The occurrence of the pharyngoesophageal, or Zenker diverticulum is not frequent in the national scenario, and the technique of the diverticulectomy with cricomyotomy in medium and great dimension diverticula is still the most indicated. Because the resection of the diverticulum requires the suture of the pharynx, dehiscence can occur, thereafter delaying swallowing. Hence, the idea is to accomplish this surgical procedure, comparing the manual and mechanical suture, in order to evaluate the real benefit of the mechanical technique. Aim: To evaluate the results of the pharyngoesophageal diverticulectomy with cricomyotomy using manual and mechanical suture with regard to local and systemic complications. Method: Fifty-seven patients with pharyngoesophageal diverticula diagnosed through high digestive endoscopy and pharyngeal esophagogram were studied. The applied surgical technique was diverticulectomy with myotomy of the cricopharyngeal muscle, done in 24 patients (42.2%) the mechanical suture (group A) with the mechanical linear suture device and in 33 (57.8%) a manual closure of the pharynx (group B). Results: In the postoperative period, one patient of group A (4.1%) presented fistula caused by dehiscence of the pharyngeal suture, and three of group B (15.1%) presented the same complication, with a good outcome using a conservative treatment. In the same group, three patients (9.0%) presented stenosis of the suture of the pharynx, with good outcome and with endoscopic dilatations, and no patient from group A presented such complication. Lung infection was present in five patients, being two (8.3%) of group A and three (9.0%) on B, having good outcomes after specific treatment. In the late review, done with 43 patients (94.4%) of group A and 22 (88.0%) on B, the patients declared to be pleased with the surgical procedure, because they were able to regain normal swallowing. Conclusion: The diverticulectomy with myotomy and pharyngeal closure using mechanical suture was proven appropriate, for having restored regular swallowing in most of the patients, and the mechanical closure of the pharynx proved to be more effective in comparison to the manual one, because it provided a lower index of local post-surgical complications.

Racional: A ocorrência do divertículo faringoesofágico, ou de Zenker, é pouco frequente no cenário nacional, sendo que a técnica da diverticulectomia com cricomiotomia em divertículos de média e grandes dimensões ainda é a mais indicada. Devido à ressecção do divertículo necessitar de sutura da faringe ocorre possibilidade de deiscência, o que retarda o retorno da deglutição. Daí a ideia de realizar este procedimento cirúrgico, comparando a sutura manual com a mecânica, para avaliar o real benefício da técnica mecânica. Objetivo: Avaliar os resultados da diverticulectomia faringoesofágica com cricomiotomia utilizando à sutura manual e mecânica em relação às complicações locais e sistêmicas. Métodos: Foram estudados 57 pacientes com divertículos faringoesofágicos diagnosticados através da endoscopia digestiva alta e faringoesofagograma. A técnica cirúrgica empreendida foi a diverticulectomia com miotomia do músculo cricofaríngeo, sendo a sutura mecânica realizada em 24 pacientes (42,2%, grupo A) com o aparelho linear e em 33 (57,8%, grupo B) a manual para o fechamento da faringe. Resultados: Na avaliação do pós-operatório precoce, um paciente do grupo A (4,1%) apresentou fístula consequente à deiscência da sutura da faringe e três do grupo B (15,1%) ambos com boa evolução com tratamento conservador. Neste mesmo grupo, três pacientes (9,0%) apresentaram estenose da sutura da faringe, com boa evolução com dilatações endoscópicas sendo que nenhum do grupo A apresentou esta complicação. A infecção pulmonar esteve presente em cinco pacientes, dois (8,3%) do grupo A e três (9,0%) do grupo B, com boa evolução com tratamento específico. Na avaliação tardia, realizada em 43 pacientes, 17(94,4%) do grupo A e 22 (88,0%) do grupo B, os pacientes referiram estarem satisfeitos com o procedimento cirúrgico, pois conseguiram resgatar a deglutição normal. Conclusões: A diverticulectomia com a miotomia do cricofaríngeo demonstrou ser procedimento cirúrgico ...

Abordagem endoscópica do divertículo de Zenker / Endoscopic approach for Zenkers diverticulum

O Divertículo de Zenker (DZ) é o mais comum dos divertículos do esôfago. Consiste numa desordem rara caracterizada pela protrusão da hipofaringe posterior numa região de fragilidade anatômica. É uma doença do idoso, do sexo masculino que tem, como principal sintoma, a disfagia e possui tratamento essencialmente cirúrgico. O objetivo deste estudo é relatar quatro casos clínicos de divertículo de Zenker com enfoque para o tratamento endoscópico dessa afecção, demonstrando as principais vantagens desse procedimento em relação às técnicas de cirurgia aberta.

Zenkers diverticulum is the most common esophageal diverticula. It is a rare disorder characterized by the protrusion of the posterior hypopharynx in an anatomic weak region. It is a male, elderly disease whose main symptom is dysphagia and it has surgical treatment essentialy. The aim of this study is to report four clinical cases of Zenkers diverticulum focusing on endoscopic management of this problem, showing the main advantages of this procedure compared to open surgery techniques.

Dysphagia Lusoria and Zenker's Diverticulum / Dysphagia Lusoria y Diverticulum de Zenker. Reporte de caso

An 81-year-old woman was referred for evaluation of dysphagia which she had suffered for four years. An upper gastrointestinal endoscopy revealed a Zenker's diverticulum and extrinsic compression of the esophagus. A thoracic CT scan confirmed the presence of extrinsic compression caused by an aberrant right subclavian artery, which compromised the posterior esophageal wall thus confirming a diagnosis of dysphagia lusoria. An association between Zenker's diverticulum and dysphagia lusoria is so uncommon that there have been no previously published cases.

Una mujer de 81 años fue remitida para evaluación de una disfagia que padecía desde hacía cuatro años. Una endoscopia gastrointestinal reveló un divertículo de Zenker y una compresión extrínseca del esófago. Un escaneo computadorizado del tórax confirmó la presencia de la comprensión extrínseca, causada por una arteria subclavia derecha aberrada, que comprometía la pared esofágica posterior, lo que confirmó un diagnóstico de disfagia lusoria. Una asociación entre el divertículo de Zenker y la disfagia lusoria es tan poco común que no han sido publicados sus casos con anterioridad.
