III BRAZILIAN CONSENSUS STATEMENT ON ENDOSCOPIC ULTRASOUND.

Background: In the past decades, endoscopic ultrasound has developed from a diagnostic tool to a platform for many therapeutic interventions. Various technological advancements have emerged since the last Brazilian Consensus, demanding a review and update of the recommendations based on the best scientific evidence.

Methods: A group of 32 renowned echoendoscopists selected eight relevant topics to be discussed to generate clinical questions.

The role of endoscopic ultrasound in the staging of tracheal neoplasm: a brief review.

Our case report shows the complexity of dealing with tracheal tumors, highlighting the importance of the method used for staging. In this report, endoscopic ultrasound (EUS) was crucial to identify the involvement of the esophageal muscular propria in a tracheal tumor and change the surgical planning of the case. Staging this kind of tumor represents a challenge for physicians.

ENDOSCOPIC BAND LIGATION FOR THE TREATMENT OF HEMORRHOIDAL DISEASE.

Background: There are several therapeutic options for symptomatic hemorrhoids, from hygienic and dietary measures to conventional surgery. The best technique adopted for alternative and non-surgical treatment for intermediate grade (II and III) hemorrhoidal disease is rubber band ligation. More recently, the technique has been used with the aid of a gastroscope and a kit of elastic rubber bands for esophageal varices.

Rapid on-site cytopathological examination (ROSE) performed by endosonagraphers and its improvement in the diagnosis of pancreatic solid lesions.

Purpose: To evaluate the diagnosis improvement of EUS-FNA when using ROSE performed by the endosonographer.

Methods: A retrospective study was conducted. A total of 48 pancreatic solid masses EUS-FNA were divided into two groups according to the availability of on-site cytology (ROSE) - the first 24 patients (group A-without ROSE) and the latter 24 cases (group B-with ROSE).

Reliability in endoscopic diagnosis of portal hypertensive gastropathy.

Aim: To analyze reliability among endoscopists in diagnosing portal hypertensive gastropathy (PHG) and to determine which criteria from the most utilized classifications are the most suitable.

Methods: From January to July 2009, in an academic quaternary referral center at Santa Casa of São Paulo Endoscopy Service, Brazil, we performed this single-center prospective study. In this period, we included 100 patients, including 50 sequential patients who had portal hypertension of various etiologies; who were previously diagnosed based on clinical, laboratory and imaging exams; and who presented with esophageal varices.

Inflammatory bowel disease activity assessed by fecal calprotectin and lactoferrin: correlation with laboratory parameters, clinical, endoscopic and histological indexes.

Background: Research has shown that fecal biomarkers are useful to assess the activity of inflammatory bowel disease (IBD). The aim of the study is: to evaluate the efficacy of the fecal lactoferrin and calprotectin as indicators of inflammatory activity.

Findings: A total of 78 patients presenting inflammatory bowel disease were evaluated.
