Echoendoscopy with elastography in mediastinal lymph nodes.

Elastography is a widely used procedure in conventional ultrasonography that has recently been incorporated in echoendoscopy. This is an innovative and promising technology that aims to increase the negative predictive value of endoscopic ultrasonography and fine-needle aspiration punctures. It is useful for directing punctures in suspect areas and, consequently, improves diagnostic performance.

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.

Minimally invasive endoscopic treatment of necrotizing pancreatitis: A case report with images and review of the literature.

Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.

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).

Modified "Roux en Y" hepaticojejunostomy to permit transgastric endoscopic access.

Purpose: To present an option technique during the accomplishment of a "Roux-en-Y" hepaticojejunostomy that, allows future transgastric endoscopic access to the biloenteric anastomosis.

Methods: The side-to-side "Roux-en-Y" hepaticojejunostomy is carried through transmesocolic, retrogastric short tunnel. A distal jejunal loop of approximately 10,0 to 15,0 cm must be kept far from the anastomosis that allows its setting, without tension, in the anterior gastric wall bellow the small bending, between body and of the stomach antrum.

Rectal cancer staging: Correlation between the evaluation with radial echoendoscope and rigid linear probe.

Background And Objectives: The National Cancer Institute estimated 40,340 new cases of rectal cancer in the United States in 2013. The correct staging of rectal cancer is fundamental for appropriate treatment of this disease. Transrectal ultrasound is considered one of the best methods for locoregional staging of rectal tumors, both radial echoendoscope and rigid linear probes are used to perform these procedures.

Endoscopic ultrasonography-fine-needle aspiration of solid pancreatic lesions: A prospective, randomized, single-blinded, comparative study using the 22 Gauge EchoTip® ProCoreTM HD (A) and the 22 Gauge EchoTip® Ultra HD (B) endoscopic ultrasound needles.

Introduction: In order to improve diagnostic efficacy of pancreatic masses, a new endoscopic ultrasonography-fine-needle aspiration (EUS-FNA) needle was developed (EchoTip(®) ProCore™ HD). Very few studies have compared these two needles and none could avoid selection biases.

Aims: The present study intends to compare the results obtained by these two needles when performing EUS-FNA of pancreatic solid lesions.

Endoscopic ultrasound-guided fine needle aspiration for the diagnosis of nonfunctional paragangliomas: a case report and review of the literature.

Paraganglioma is a rare tumor that should be included in the differential diagnosis of retroperitoneal tumors. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has emerged as an effective tool in the diagnosis of these lesions. A 37-year-old female patient with a history of microcytic anemia underwent EUS-FNA and was diagnosed with a neuroendocrine tumor by histopathological and immunohistochemical analysis.
