RESUMO

RESUMEN La resección gástrica atípica ha demostrado ser beneficiosa para tumores submucosos. La técnica pre senta mayor riesgo cuando estos se desarrollan próximos a la unión esófago-gástrica (UEG). Para esta limitación se propuso la resección intragástrica mediante una técnica mixta combinando laparoscopia y endoscopia. En nuestro medio no existen publicaciones al respecto. Se trata de una mujer de 42 años, con lesión subepitelial-subcardial de 2 cm, evaluada mediante videoendoscopia alta (VEDA), compa tible con tumor del estroma gastrointestinal (GIST) evaluado mediante ecoendoscopia. La lesión fue resecada mediante abordaje combinado laparoendoscópico. Bajo visión laparoscópica se introdujeron en cavidad abdominal trocares con balón, y bajo visión endoscópica intragástrica se introdujeron estos en el estómago y se fijó la pared gástrica a la pared abdominal insuflando dichos balones. Posterior mente se realizó la resección de la lesión con sutura mecánica. El abordaje combinado es seguro y eficaz, simple en manos entrenadas, pero constituye una opción reproducible en casos seleccionados.


ABSTRACT Atypical gastric resection has proved to be beneficial to treat submucosal tumors. The technique is more difficult when these tumors develop next to the gastroesophageal junction (GEJ). Intragastric resection combining endoscopic and laparoscopic approach was proposed to solve this limitation. There are no publications about this technique in our environment. A 42-year-old female patients with a 2-mm subepithelial tumor below the cardia evaluated by upper gastrointestinal (UGI) videoendoscopy and endoscopic ultrasound suggestive of a gastrointestinal stroma tumor (GIST) underwent resection using the combined laparo-endoscopic approach. Under laparoscopic guidance, balloon-tipped trocars were introduced in the abdominal cavity and then into the stomach using endoscopic view. The balloons were inflated to fix the gastirc wall to the abdominal wall. The lesion was resected using mechanical stapler. The combined approach is safe and efficient, and simple to perform for trained professionals, constituting a reproducible option in selected cases.

RESUMO

RESUMEN La unión del tubo esofágico con el estómago en lo que denominamos el cardias, su tránsito y relacio nes con el hiato diafragmático, las estructuras fibromembranosas que la fijan y envuelven, la existencia de un esfínter gastroesofágico anatómico y su real morfología, así como la interacción de todos estos elementos, han sido materia de controversia por décadas y aún hoy. Este artículo actualiza la descrip ción de tales estructuras.


ABSTRACT The point where the esophagus connects to the stomach, known as the cardia, its transition and re lationship with the diaphragmatic hiatus, its fibromembranous attachments, the existence of an ana tomic gastroesophageal sphincter and its real morphology, and the interaction between all these ele ments, have been subject of debate for decades that still persist. The aim of this article is to describe the updated information of such structures.

RESUMO

Gastric cancer (GC) is the fifth most common cancer worldwide with a varied geographic distribution and an aggressive behavior. In Spain, it represents the sixth cause of cancer death. In Western countries, the incidence is decreasing slightly, with an increase in gastroesophageal junction adenocarcinoma (GEJA), a different entity that we separate specifically in the guideline. Molecular biology advances have been done recently, but do not yet lead to the choice in treatment approach except in advanced disease with overexpression of HER2. Endoscopic resection in very early stage, perioperative chemotherapy in locally advanced tumors and preliminary immune therapy resulting in advanced disease are the main treatment innovations in the GC/GEJA treatment. We describe the different evidences and recommendations following the statements of the American College of Physicians.

RESUMO

Background: Heller myotomy and laparoscopic fundoplication represents the best treatment option for esophageal achalasia, with effective short- and long-term success. However, treatment options in patients in whom primary surgery failed represent a real challenge. We present the resection of the gastroesophageal junction (GEJ) along with a Roux-en-Y reconstruction as a treatment alternative. Materials and Methods: We analyzed the course of 5 patients with achalasia undergoing the resection of the GEJ along with a Roux-en-Y reconstruction for recurrent dysphagia after Heller myotomy and fundoplication, with at least 1 year of follow-up. Symptoms questionnaire and minuted esophagogram before and after treatment were performed in all the patients. Results: Five patients underwent resection of the GEJ along with a Roux-en-Y reconstruction. All the patients had dysphagia and 60% had regurgitations. Eighty percent of the patients had more than one previous redo surgery and 100% had had multiple dilations. Preoperative contrast esophagram of 3 patients show Stage II disease (mild and mark dilated esophagus) and 2 patients with Stage III disease (one esophageal curve and severe dilation). Manometry confirmed the diagnosis. At a mean follow-up of 34 months, all the patients reported a marked improvement in dysphagia, with median overall satisfaction rating of 9 (range 7-10), no symptom of gastroesophageal reflux disease (GERD), and good esophageal emptying in the postoperative contrast esophagram. Conclusions: The resection of the GEJ and Roux-en-Y reconstruction is an excellent treatment for recurrent dysphagia after Heller myotomy. All the patients reported a marked improvement of their dysphagia. No symptoms of GERD were documented after the surgery. This procedure should be taken into account as an alternative to esophagectomy for recurrent dysphagia.

RESUMO

The 7th edition of Union for International Cancer Control (UICC) staging system moved gastroesophageal junction (GEJ) cancers from gastric to esophageal group. Since clinical management is strongly influenced by this staging system, we looked at molecular fingerprints of GEJ tumors and compared to gastric and esophageal profiles. We aimed at elucidating whether GEJ cancers cluster with gastric or esophageal groups according to mRNA and microRNA expression pattern, since this might represent tumor identity. The clinical and expression data were downloaded from The Cancer Genome Atlas (TCGA) with 395 stomach, 184 esophagus and 521 colon samples for mRNA analyses and 392 stomach, 175 esophagus and 459 colon samples for microRNA comparisons. Both Principal Component Analysis (PCA) and Heat Map plots were performed in R platform, using Log2 transformation of RPKM normalized data. Differential Expression Analysis was also performed in R, using RAW data and the DESeq2 package. The mRNAs and microRNAs were tagged as differentially expressed if they met the following criteria: i) FDR adjusted p-value < 0.05; and ii) |Log2 (fold-change)| > 2. Esophagus squamous cell carcinoma (ESCC) clustered apart of the others tumors, while adenocarcinomas (AC) clustered all together according to both mRNAs and microRNAs expression patterns. The HMs of the differentially expressed mRNAs and microRNAs also demonstrated that ESCC belongs to a different group, while AC molecular signature of esophagus looks like AC of the cardia and non cardia regions. Even distal gastric cancers are quite similar to AC of the lower esophagus, demonstrating that esophagus AC relies much closer to gastric cancers than to esophagus cancers. By using robust molecular fingerprints, it was strongly demonstrated that GEJ tumors looks more like gastric cancers than esophageal cancers, despite of tumor heterogeneity.

RESUMO

Resumen Los tumores de células pequeñas extrapulmonares pueden aparecer en múltiples órganos y forman una rara afección clínico-patológica de tumores neuroendocrinos, con gran proliferación epitelial y con comportamiento biológico agresivo. El tubo gastrointestinal es la fuente más común de tumores de células pequeñas extrapulmonares. Nuestro caso clínico describe un paciente con carcinoma de células pequeñas en la unión gastroesofágica, que fue diagnosticado en el contexto de sangrado de tubo digestivo alto. Se excluyó un tumor pulmonar primario; el paciente recibió quimioterapia, quimiorradioterapia y radioterapia cerebral profiláctica, con buena evolución clínica. Nuestro caso se trata de una rara afección clínica, lo que evidencia la importancia de diagnosticar enferemedades poco frecuentes. Existe poca evidencia en la bibliografía de cómo deben tratarse estos pacientes.


Abstract Extrapulmonary small cell carcinomas (EPSCC) can arise in multiple organ sites and form a rare clinicopathological entity of high proliferative epithelial neuroendocrine tumors with aggressive biological behavior. Gastrointestinal is the most common source of EPSCC. We report a case of gastroesophageal junction small cell carcinoma, which was diagnosed in the context of upper gastrointestinal bleeding. A primary small cell lung carcinoma was excluded. Chemotherapy, neoadjuvant chemoradiotherapy and prophylactic cranial radiotherapy were given, with good clinical outcome. Our case of a very rare condition highlights the importance of recognizing atypical pathologic diagnoses. More research needs to be conducted with EPSCC patients in order to better characterize disease pathogenesis, and an optimal disease management.

RESUMO

Los patrones de incidencia de las neoplasias de esófago vienen presentando cambios en las últimas décadas. Es así como en hombres, el adenocarcinoma de esófago es ahora más frecuente que el carcinoma epidermoide. Hay evidencia en las diferencias del comportamiento biológico de los adenocarcinomas y dentro de los mismos carcinomas de células escamosas de acuerdo con su localización. Muchas discrepancias existen en la literatura respecto a la etiología, clasificación y tratamiento quirúrgico para estos tumores. Los adenocarcinomas de la unión gastroesofágica incluyen a los tumores originados en el esófago distal con invasión de la unión gastroesofágica, a los cardiales y a los originados en el estómago proximal. Generalmente se utiliza la clasificación topográfica propuesta por Siewert y Stein, que divide a los tumores en tipo I, cuando hay compromiso proximal a la unión gastroesofágica, tipo II, encontrados directamente en el cardias, y tipo III, encontrados en el estómago proximal. Hacemos la presentación de tres casos. Se lleva a cabo una revisión del enfoque diagnóstico y del manejo de estas lesiones.


Patterns of esophageal tumor incidence have changed in recent decades, now esophageal adenocarcinomas have become more common than squamous cell carcinoma among men. There is evidence of biological differences in behavior among adenocarcinomas and squamous cell carcinomas according to their locations. Many discrepancies exist in the literature regarding the etiology, classification and surgical treatment for these tumors. Adenocarcinomas of the gastroesophageal junction include tumors that arise in the distal esophagus as a result of invasion from the proximal stomach through the gastroesophageal junction and the cardiac glands. The usual topographic classification is that proposed by Siewert and Stein. It divides tumors into Type 1, which is used when the compromise is proximal to the gastroesophageal junction, Type 2 when the tumor is found directly in the cardia, and Type 3 when the tumor is in the proximal stomach. Here we present three cases and a review of the diagnostic approach to, and management of, these lesions.
