BACKGROUND ERCP can be associated with serious complications. Difficulty in common bile duct (CBD) cannulation is one of the main risk factors for post-ERCP pancreatitis. The double-guidewire technique (DGT) has been considered a promising alternative approach in difficult cannulation situations. OBJECTIVE To compare the performance of DGT with the(More)
Endoscopic submucosal dissection (ESD) has important advantages over endoscopic mucosal resection (EMR) for early gastrointestinal neoplasia treatment, but its difficult learning curve and associated risks have constrained its wider expansion. ESD training includes a comprehensive study of ESD basics, attending live cases and performing initial(More)
Splenic rupture (SR) after colonoscopy is a very rare but potentially serious complication. Delayed diagnosis is common, and may increase morbidity and mortality associated. There is no clear relation between SR and difficult diagnostic or therapeutic procedures, but it has been suggested that loop formation and excessive torquing might be risk factors.(More)
BACKGROUND & AIMS After endoscopic mucosal resection (EMR) of colorectal lesions, delayed bleeding is the most common serious complication, but there are no guidelines for its prevention. We aimed to identify risk factors associated with delayed bleeding that required medical attention after discharge until day 15 and develop a scoring system to identify(More)
OBJECTIVE To describe the administration of drugs through nasogastric tubes by the nursing staff of a tertiary hospital and to identify the most common administration errors. METHODS An observational study was carried out between November of 2010 and March of 2011. The study population was the nursing staff of the hospital. A questionnaire was created(More)
Over the last few years, endoscopic submucosal dissection (ESD) has shown to be effective in the management of early colorectal neoplasms, particularly in Asian countries where the technique was born. In the Western world, its implementation has been slow and laborious. In this paper, the indications for ESD, its learning model, the available methods to(More)
Antimicrobial stewardship programmes promote excellence in the use of antimicrobials by selecting the appropriate antimicrobial agent and the correct dose, route of administration and duration of treatment. However, there is limited experience with such programmes targeting antifungal treatments. We present the results of a non-compulsory programme for the(More)
OBJECTIVE To analyze difficulties in achieving optimal adherence to antiretroviral therapy as perceived by pediatric patient caregivers in relation to treatment characteristics. METHODS Design of a subjective numeric scale-based questionnaire, and its administration to caregivers of pediatric patients undergoing active antiretroviral therapy in our(More)
AIM This study was designed to analyse the drug consumption difference and economic impact of an antibiotic sequential therapy focused on quinolones. METHOD We studied the consumption of quinolones (ofloxacin/levofloxacin and ciprofloxacin) 6 months before and after the implementation of a sequential therapy program in hospitalised patients. It was(More)
