IS ENDOSCOPIC SUBMUCOSAL DISSECTION STILL LIMITED TO FEW TERTIARY CENTERS IN THE WEST? RESULTS FROM A NATIONAL SURVEY IN BRAZIL.

Background: Endoscopic submucosal dissection (ESD) enables en bloc excision of superficial neoplasms. Although ESD is widely practiced in Eastern countries like Japan, South Korea and China, its use in the West is supposed to be still limited to few tertiary centers.

Objective: This study aimed to investigate the clinical practice of ESD in Brazil by means of an electronic questionnaire elaborated by the Brazilian Society of Digestive Endoscopy (SOBED).

Risk of lymph node metastasis in early gastric cancer and indications for endoscopic resection: is it worth applying the east rules to the west?

Background: Early gastric cancers are associated with lymph node metastasis (LNM) in 15% of cases. Risk factors for LNM are well established in Eastern countries. Less invasive treatments, such as endoscopic or surgical laparoscopic resection, are well accepted in Eastern countries and a matter of intense debate in the West, were indications for such treatments are still contested The objective of the study is to determine risk factors related to LNM and to validate endoscopic resection indications.

ADENOMA DETECTION RATE EVALUATION AND QUALITY OF COLONOSCOPY IN THE CENTER-WEST REGION OF BRAZIL.

Background: Colorectal cancer is the third commonest cancer in men and the second in women worldwide. Peculiarities of its evolution allow secondary prevention measures through colonoscopy, with high diagnostic and therapeutic capacity. In this context, the quality indicators of the procedure become important, among them the adenoma detection rate (ADR).

Risk factors for esophageal cancer in a low-incidence area of Brazil.

CONTEXT AND OBJECTIVES Esophageal cancer is the eighth commonest type of cancer worldwide, occupying sixth place in terms of mortality. Smoking and alcohol use are known risk factors for this type of cancer. The aim here was to evaluate the risk factors for esophageal cancer in a low-incidence area.

Frequency and predictive factors related to lymphatic metastasis in early gastric cancer.

Background: The standard treatment of gastric cancer still has high morbidity and mortality in western populations. Groups of patients with negligible risk of lymph node metastasis may benefit from less invasive treatments. Data regarding the frequency and predictive factors related to lymphatic metastasis in early gastric cancer are rare.

Peristomal infection in percutaneous endoscopic gastrostomy (PEG): a comparative study of two gastropexy techniques in a before-and-after design.

Introduction: Percutaneous endoscopic gastrostomy (PEG) performed using the Pull technique is associated with a high rate of surgical infections. When PEG is performed using the Introducer technique, a lower rate of infection is seen. However, this technique can pose technical difficulties during gastropexy.

Initial experience in Brazil with endoscopic submucosal dissection for early gastric cancer using insulation-tipped knife: a safety and feasibility study.

Background: Endoscopic resection is an adequate treatment for subgroups of patients with early gastric cancer. Endoscopic submucosal dissection (ESD) represents a recent advance and leads to good results when adequately indicated. There is great experience with this technique in Japan and it is gaining acceptance among Western endoscopists.

Endoscopic mucosal resection of early gastric cancer: initial experience with two technical variants.

Background: When performed in carefully selected cases, the endoscopic treatment of early gastric cancer yields results which are comparable to the conventional surgical treatment, but with lower morbidity and mortality and better quality of life. Several technical options to perform endoscopic mucosal resection have been described and there is a large amount of accumulated experience with this procedure in eastern countries. In western countries, particularly in Brazil, technical limitations associated with the small number of cases of early gastric cancer reflect the little experience with this therapeutic mode.

Metastatic cancer to the stomach.

Background: Metastases in the stomach are rare. The increased use of esophagogastroduodenoscopy (EGD), associated with better treatment results for malignancies, requires them to be acknowledged. The aim of this study was to describe a series of cases of metastasis to the stomach, their primary sites, clinical and endoscopic features, treatment, and results.
