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 use of the cap and underwater technique as an aid in endoscopic diagnosis and treatment of upper gastrointestinal bleeding: case series.

Background And Aims: Upper GI bleeding (UGIB) is a medical emergency associated with elevated mortality and significant costs to the health care system. EGD is currently the method of choice for the diagnosis and management of these conditions. However, the location of bleeding lesions and technical difficulties in achieving endoscope stability may challenge even the most experienced endoscopists.

Pancreas-preserving duodenectomy after living donor liver transplantation for invasive cytomegalovirus disease.

CMV infection plays an important role in the postoperative course following solid organ transplantation. We present the case of an 11-year-old male patient who underwent LDLT due to severe hepatopulmonary syndrome and biliary cirrhosis. Four weeks after LDLT, he developed persistent GI bleeding and was subjected to repeated endoscopic treatment and radiological arterial embolization to stop the bleeding from duodenal ulcers.

Septotomy and Balloon Dilation to Treat Chronic Leak After Sleeve Gastrectomy: Technical Principles.

Background: Chronic leaks after laparoscopic sleeve gastrectomy (LSG) are often difficult to treat by endoscopy metallic stent. Septotomy has been indicated as an effective procedure, but the technical aspects have not been detailed in previous publications (Campos JM, Siqueira LT, Ferraz AA, et al., J Am Coll Surg 204(4):711, 2007; Baretta G, Campos J, Correia S, et al.

Protective action of green tea catechins in neuronal mitochondria during aging.

Mitochondria are central players in the regulation of cell homeostasis. They are essential for energy production but at the same time, reactive oxygen species accumulate as byproducts of the electron transport chain causing mitochondrial damage. In the central nervous system, senescence and neurodegeneration occur as a consequence of mitochondrial oxidative insults and impaired electron transfer.
