Gastroesophageal reflux disease (GERD) is a common chronic disorder affecting millions of people worldwide. This is a review of a number of published studies in the past year that increase current understanding or raise important issues about this disorder. Among the areas covered are the epidemiology and role of genetics in GERD; its pathogenesis with(More)

BACKGROUND The adoption of standardized protocols and specialized multidisciplinary teams for esophagectomy involve changes in routines with the implantation of expensive clinical practices and deviations from ingrained treatment philosophies. AIM To evaluate the prevalence of standardized protocols and specialized multidisciplinary teams in São Paulo(More)
BACKGROUND The use of prosthetic materials to reinforce the abdominal wall is associated with a low index of recurrence; however, intraperitoneal placement of a foreign body may lead to adhesions. The present investigation was designed to determine adhesion formation with commercially available meshes implanted laparoscopically in rabbits. METHODS Three(More)
BACKGROUND/AIMS Endoscopic therapy for esophageal varices may lead to esophageal dysmotility. High-resolution manometry is probably the more adequate tool to measure esophageal motility in these patients. This study aimed to evaluate esophageal motility using high resolution manometry following eradication of esophageal varices by endoscopic sclerotherapy.(More)
BACKGROUND The upper esophageal sphincter is composed of striated muscle. The stress of intubation and the need to inhibit dry swallows during an esophageal manometry test may lead to variations in basal pressure of this sphincter. Upper esophageal sphincter is usually only studied at the final part of the test. Was observed during the performance of high(More)
Multichannel intraluminal impedance (MII) for the evaluation of esophageal diseases was created in 1991 trying to solve previous limitations of esophageal function test. MII-pH is able to determine the physical characteristics of the refluxate (liquid, gas, or mixed) and nonacidic GER. MII-manometry can determine the presence of bolus and its relation with(More)
BACKGROUND AND OBJECTIVES Biliary leakage through the cystic duct stump due to clip dislodgement has been a concern since the advent of the laparoscopic cholecystectomy. The authors proposed a cadaveric model to test the safety of cystic duct clipping in a hypertensive biliary tract in healthy and cirrhotic livers. METHODS Twenty fresh cadavers were(More)
