Duplicación esofágica: caso clínico / Esophageal duplication: a case report

We report an 11-month infant case, who consults electively to perform a laparoscopic Nissen fundoplication, given her background of gastro-esophageal reflux and hiatal hernia. Intraoperatively, a malformation of the distal third of the esophagus was found. The preoperative images showed no evidence of the lesión. The lesión was resected and sent to anatomopathologic analysis, confirming the diagnosis.

Se presenta el caso de una lactante de 11 meses con antecedentes de reflujo gastroesofágico y hernia hiatal que ingresa electivamente a la Sección de Cirugía Pediátrica, con el objetivo de realizar una fundoplicatura de Nissen laparoscópica. En el intraoperatorio se detecta una malformación en el tercio distal del esófago. En las imágenes realizadas previamente no se observó una alteración compatible. La lesión fue resecada y luego analizada en anatomía patológica, confirmándose el diagnóstico de una duplicación esofágica.

Isolated oesophageal cyst connected with the bronchus

We report an unusual case of a patient with an oesophageal cyst connected to the bronchus. A 24-year old male with a two-year history of repeated attacks of chest infection and haemoptysis was found to have a cyst of 4 x 4 cm affecting the anterior and apical segments of the right upper lobe. The cyst was excised in its entirety and the histopathological study of the cyst showed stratified squamous epithelium with submucosal and muscular layer but no cartilage. The pathological diagnosis was an oesophageal cyst. No previous case of isolated oesophageal cyst connected to the bronchus has been reported according to the available literature.

Unusual Bronchopulmonary Foregut Malformation Associated with Pericardial Defect: Bronchogenic Cyst Communicating with Tubular Esophageal Duplication

We report a case of unusual bronchopulmonary foregut malformation composed of a mediastinal bronchogenic cyst with sequestrated lung tissue and communicating tubular esophageal duplication associated with complete pericardial defect. A 18-yrold man, who had suffered from dry cough and mild dyspnea, was admitted because of an incidentally detected chest mass. A computed tomography scan demonstrated a cystic mass with an air fluid level connected with esophagus in the middle mediastinum. The surgically resected mass was a pleural invested accessory lobe of the lung (8.0x7.0x4.5 cm) connected with the esophageal wall by a tubular structure (3.0 cm in length and 2.0 cm in diameter). A complete left pericardial defect was also identified. Histologically, the cystic wall was composed of fibrovascular connective tissue with a smooth muscle layer, mixed seromucous glands and cartilage, and the inner surface of the cyst was lined by ciliated pseudostratified columnar epithelium. The inner surface of the tubular structure was lined by non-keratinizing or keratinizing squamous epithelium, and the wall contained submucosal mucous glands, muscularis mucosa, and duplicated muscularis propria. This case is important in understanding the embryological pathogenesis of the variable spectrum of the bronchopulmonary foregut malformation.

Intra-abdominal Esophageal Duplication Cyst in an Adult

Esophageal duplication cysts are congenital anomalies of the foregut that are rarely found in the abdomen. An accurate preoperative diagnosis is not always possible, so the definitive diagnosis can be made by histologic examination of the surgical specimen. We experienced a case of Intra-abdominal esophageal duplication cyst in a 52-year-old female, who initially presented with an esophageal submucosal tumor on upper gastrointestinal endoscopy. She did not have any gastrointestinal symptoms. Barium esophagography, chest computed tomography scan and endoscopic ultrasonography demonstrated the cystic lesion in the intra-abdominal esophagus. Transhiatal enucleation of the lesion was performed successfully via the abdominal approach with no postoperative complications. Histologic study showed that the cyst wall contained a two-layered muscle coat and the surface of the lumen was lined by pseudo-ciliated columnar epithelium. The patient has been doing well without any complaints for 3 months of follow-up period.

Quiste esofágico de duplicación / Esophageal duplication cyst

El quiste esofágico de duplicación es una patología intratorácica infrecuente. Presentamos un paciente de 38 años que consulta por afagia brusca y dolor retroesternal, al que se estudió mediante Rx, endoscopia y TC, realizándose el diagnóstico definitivo por anatomía patológica

Tumores benignos de esófago / Benign esophageal tumors

Los tumores benignos de esófago constituyen una entidad patológica poco frecuente, ocupando el 0,5 a 0,8 por ciento de las neoplasias de esófago. Se dividen en intraluminales, intramurales y extramurales. Se localizan más frecuentemente en el tercio distal y la mayoría corresponden a leiomiomas (50 por ciento). Otros tipos de lesiones son los fibromas, lipomas, neurofibromas y pólipos. Los leiomiomas se presentan en gente joven. La edad promedio de presentación es de 38 años. Pueden ser múltiples (3-10 por ciento). Se diagnostican con radiografía de esófago estómago y duodeno e idealmente con ecografía endoscópica. El tratamiento ideal es la enucleación quirúrgica que se efectúa en los tumores mayores de 5 cm. Entre los otros tumores el schwannoma es el tumor primario benigno más frecuente del mediastino, aunque representa sólo el 8 por ciento de todos ellos. Se presenta más frecuentemente en la mujer entre la quinta y sexta década de la vida. La biopsia endoscópica tiene un alto porcentaje de error. Se presenta caso clínico de una paciente con un schwannoma esofágico que se intervino en nuestro servicio practicándose una esofagectomía parcial con buen resultado
