Preditores de prognóstico nos Tumores Neuroendócrinos Gástricos: um estudo retr...

Resumo Introdução/Objetivo: Os tumores neuroendócrinos gástricos (TNEs-G) têm frequentemente um curso indolente, apesar do seu potencial metastático. O objetivo deste trabalho foi identificar fatores de prognóstico associados à sobrevida global e à metastização nos doentes com TNEs-G e avaliar o impacto da análise seriada de cromogranina A (CgA). Methods: Estudo retrospectivo in-cluindo doentes consecutivos admi...

Anastomotic Leaks following Esophagectomy for Esophageal and Gastroesophageal J...

Abstract Introduction: Anastomotic leakage after esophagectomy is associated with high mortality and impaired quality of life. Aim: The objective of this work was to determine the effec-tiveness of management of esophageal anastomotic leakage (EAL) after esophagectomy for esophageal and gastro-esophageal junction (GEJ) cancer. Methods: Patients submitted to esophagectomy for esophageal and GEJ cancer at a terti...

Endoscopic Resection of Gastrointestinal Neuroendocrine Tumors: Long-Term Outco...

Abstract Introduction: Gastrointestinal neuroendocrine tumors (GI-NETs) are being more frequently diagnosed and treated by endoscopic resection (ER) techniques. However, comparison studies of the different ER techniques or long-term out-comes are rarely reported. Methods: This was a single-center retrospective study analyzing short and long-term outcomes after ER of gastric, duodenum, and rectal GI-NETs. Compar...

Anastomotic Leakages after Surgery for Gastroesophageal Cancer: A Systematic Re...

Abstract Introduction: With the increase of esophageal and gastric cancer, surgery will be more often performed. Anastomotic leakage (AL) is one of the most feared postoperative complications of gastroesophageal surgery. It can be managed by conservative, endoscopic (such as endoscopic vacuum therapy and stenting), or surgical methods, but optimal treatment remains controversial. The aim of our meta-analysis wa...

Gastric Cancer: A Practical Review on Management of Individuals with Hereditary...

Abstract Gastric adenocarcinoma is one of the most frequent and deadly cancers worldwide. However, its incidence is variable, being higher in eastern countries where screening the general population is recommended. On the other hand, in low to intermediate-risk countries, screening the general population may not be cost-effective, and therefore, it is necessary to be aware of high-risk populations that may bene...

Diagnosis of MALT Lymphoma from Surveillance Endoscopy of a Patient with a CDH1...

Abstract Carriers of the mutated CDH1 gene have an increased risk of developing early-onset signet-ring cell (diffuse) gastric cancer. We present a case of a young patient with a confirmed mutation of the CDH1 gene, who was diagnosed with a gastric marginal zone B-cell lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT lymphoma) from surveillance endoscopy. He underwent Helicobacter pylori eradication tr...

Improving the Diagnosis and Treatment of Early Gastric Cancer in the West

Abstract Gastric cancer is the third leading cause of cancer-related death. In Western countries, its lower prevalence and the absence of mass screening programmes contribute to late diagnosis and a slower implementation of minimally invasive treatments. A secondary prevention strategy through endoscopic surveillance of patients at high risk of intestinal-type gastric adenocarcinoma or by screening gastric canc...

Endoscopic Skills Training: The Impact of Virtual Exercises on Simulated Colono...

Abstract Background: A previous study suggested that psychomotor training improves the performance on colonoscopy. Since then, newer exercises have been included in the latest generation of GI Mentor®. In order to optimize a colonoscopy training program, we aimed to determine the impact of 3 virtual exercises in simulated colonoscopy skills. Methods: This was a prospective and randomized study. Nineteen residen...

Neuroendocrine Tumors of the Gastrointestinal Tract: A Focused Review and Pract...

Abstract: Neuroendocrine tumors (NETs) are rare tumors derived from the neuroendocrine cell system, and more commonly found in the gastrointestinal (GI) tract. Over the last decades, the incidence of GI-NETs has been steadily increasing, partly due to the expanding indications for endoscopy. Most patients with NETs are asymptomatic, and their NETs are noticed during screening examinations; thus, endoscopists ar...
