Background: Biliary leaks have been treated with endoscopic management using different techniques with conflicting results. Furthermore the appropriate rescue therapy for refractory leaks has not been established. We evaluated the clinical effectiveness of initial endotherapy for postcholecystectomy biliary leaks using an homogenous approach (sphincterotomy + placement of a 10-French plastic stent) in a large series of patients as well as the optimal and efficacy of rescue endotherapy for refractory biliary leaks.
View Article and Find Full Text PDFIntroduction: C-reactive protein (CRP) and Bedside Index for Severity in Acute Pancreatitis (BISAP) have been used in early risk assessment of patients with AP.
Objectives: We evaluated prognostic accuracy of CRP at 24 hours after hospital admission (CRP24) for in-hospital mortality (IM) in AP individually and with BISAP.
Materials And Methods: This retrospective cohort study included 134 patients with AP from a Portuguese hospital in 2009-2010.
Objectives: Prescription of prophylactic antibiotics in acute pancreatitis (AP) is controversial. We aimed to identify the patients' characteristics that may prompt clinicians to prescribe prophylactic antibiotics in AP.
Methods: This single-center retrospective cohort study included 299 consecutive patients with AP from a Portuguese hospital in 2009 to 2010.
Background: Self-expandable metal stents (SEMSs) can be used for palliation of combined malignant biliary and duodenal obstructions. However, the results of the concomitant stent placement for the duration of the patients' lives, as well as the need for and efficacy of endoscopic revision, are unclear.
Aim: This study evaluated the clinical effectiveness of SEMS placement for combined biliary and duodenal obstructions throughout the patients' lives and the need for endoscopic revision.
Background: Pancreatic panniculitis is a rare complication of pancreatic disease occurring in 2% to 3% of all patients, most commonly those with acute or chronic pancreatitis.
Main Observations: We report the case of a pancreatic panniculitis associated with acute pancreatitis in a 63-year-old man. He presented with a 2-day history of multiple tender subcutaneous nodules, followed by nausea, vomiting, severe epigastric pain and loss of appetite, hours before admission.
Objectives: C-reactive protein (CRP) has been used widely in the early risk assessment of patients with acute pancreatitis. This study evaluated the prognostic accuracy of CRP for severe acute pancreatitis (SAP), pancreatic necrosis (PNec), and in-hospital mortality (IM) in terms of the best timing for CRP measurement and the optimal CRP cutoff points.
Materials And Methods: This was a single-center retrospective cohort study including 379 patients consecutively admitted with acute pancreatitis.
Aims: To determine the prevalence of pre-hypertension (pre-HTN) and hypertension (HTN) in Portuguese adolescents in Lisbon and to ascertain the relationship between blood pressure (BP) levels and the risk factors of gender, obesity, smoking, alcohol consumption, exercise and family history of HTN.
Methods: This was a cross-sectional study in a non-randomized sample of 234 adolescents of both sexes, aged between 16 and 19 years. Information on habits and family history of HTN was obtained through a self-completed structured questionnaire.
