BACKGROUND Patients with liver cirrhosis frequently undergo diagnostic or therapeutic upper GI endoscopy (UGIE), and the liver disease might impair the metabolism of drugs usually administered for sedation. OBJECTIVE AND SETTING To compare sedation with a combination of propofol plus fentanyl and midazolam plus fentanyl in cirrhotic outpatients undergoing(More)
According to the WHO, 16-18 million people in Central and South America are infected by Trypanosoma cruzi. Chagasic achalasia affects between 7.1% and 10.6% of the population. The aim of this study was to evaluate the effects of Botox injections in the clinical response and esophageal function of patients with dysphagia due to chagasic achalasia. In total,(More)
CONTEXT Band ligation (BL) is the most appropriate endoscopic treatment for acute bleeding or prophylaxis of esophageal variceal bleeding. Sclerotherapy with N-butyl-2-cyanoacrylate (CY) can be an alternative for patients with advanced liver disease. Bacteremia is an infrequent complication after BL while the bacteremia rate following treatment with CY for(More)
BACKGROUND Pancreatic pseudocyst endoscopic drainage has been described as a good treatment option, with morbidity and mortality rates that are lower than surgery. The aim of our study is to describe the efficacy of different forms of endoscopic drainage and estimate pseudocyst recurrence rate after short follow up period. PATIENTS AND METHODS We studied(More)
OBJECTIVE To determine whether Model for End-stage Liver Disease (MELD) Child-Turcotte-Pugh (CTP) classification, AST to platelet ratio index (APRI), and laboratory tests could predict the presence of esophageal varices (EV) or varices which need prophylactic therapy (medium or large size EV). METHODS Three hundred patients with cirrhosis (193 men; mean(More)
Retroperitoneal perforation during therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is uncommon and is usually manifested by abdominal pain, fever and leukocytosis. We report the case of a patient with post-ERCP subcutaneous emphysema, pneumomediastinum and pneumothorax treated conservatively. A 79-year-old woman with a diagnosis of(More)
AIM To evaluate the efficacy and safety of undiluted N-butyl-2 cyanoacrylate plus methacryloxysulfolane (NBCM) as a prophylactic treatment for gastric varices (GV) bleeding. METHODS This prospective study was conducted at a single tertiary-care teaching hospital between October 2009 and March 2013. Patients with portal hypertension (PH) and GV, with no(More)
BACKGROUND AND STUDY AIM Chronic radiation coloproctopathy (CRCP) is a well-recognized complication of radiotherapy, with rectal bleeding the most common presentation. It is frequently refractory to conservative management, but the optimal endoscopic treatment of bleeding secondary to CRCP is still controversial. The efficacy and safety of bipolar(More)
Chronic radiation proctopathy (CRP) is a troublesome complication of pelvic radiotherapy. The most common presentation is rectal bleeding. CRP symptoms interfere with daily activities and decrease quality of life. Rectal bleeding management in patients with CRP represents a conundrum for practitioners. Medical therapy is ineffective in general and surgical(More)
BACKGROUND The results of variceal band ligation (VBL) in patients with advanced liver disease are unknown. Cyanoacrylate injection (CI) might have a better outcome than VBL in the treatment of esophageal varices (EV) in these patients. AIM To compare VBL and CI in the treatment of EV in patients with advanced liver disease. PATIENTS AND METHODS(More)
