Background Recommendations for the duration of antimicrobial therapy in cholangitis after successful endoscopic biliary drainage vary. The aim of this study was to compare the occurrence of local infectious complications in patients with acute cholangitis treated with antibiotics for 3 days or less compared with 4 days or more. Methods We performed a retrospective multicentre study in seven hospitals in the Netherlands. Patients who received a successful biliary drainage by endoscopic retrograde cholangio-pancreatography because of cholangitis due to common bile duct stones between 2012 and 2017 were included. The primary outcome was the occurrence of a local infectious complication within 3 months of endoscopic retrograde cholangio-pancreatography. Secondary outcomes included Clostridioides difficile infection, total length of hospital stay and all-cause mortality. Results A total of 426 patients with cholangitis were identified and 296 patients met all inclusion criteria. Therapy duration was ≤3 days in 137 patients (46.3%). During follow-up, 41 patients (13.9%) developed a local infectious complication. Occurrence of infectious complications did not differ between the two groups ( p = 0.32). No patient developed Clostridioides difficile infection. Median hospital stay was 6 days (interquartile range 4–8 days) in the short antibiotic group compared with 7 days (interquartile range 5–9 days) in the long group ( p = 0.03). Four (1.4%) patients died during follow-up, all were treated for ≥4 days ( p = 0.13 ). Conclusions Antimicrobial therapy of 3 days or less seems to be sufficient after successful biliary drainage in patients with acute cholangitis. Randomized trials should confirm our findings.
The yield of colonoscopy in patients 80 years or older was high and constant over the years. The number of tumors rose less than expected compared to the increase of elderly in the general population.
The P300 complex was derived from the electroencephalogram (EEG) as subjects mentally counted infrequent large checkerboard visual stimuli, presented randomly among frequent small checkerboard stimuli. Use of low contrast (10%) stimuli and four midline scalp electrodes, facilitated separation of cognitive and sensory components and enabled the P300 complex to be resolved into three distinct components--N200, P3a, and P3b. In 20 healthy adult subjects normative data were established and the P3a and P3b components were shown to depend on cognitive function. In 19 age-matched cirrhotic patients without overt hepatic encephalopathy (HE) the EEG and visual evoked potentials (VEPs) were normal, but latencies of P3a and/or P3b were prolonged in 9. Prolonged latencies were not associated with an abnormal number connection test. Ten additional age-matched cirrhotic patients without overt HE, who were alcohol, drug, and caffeine free, were randomized to receive flumazenil (1 mg) and placebo intravenously, double-blind. After flumazenil or placebo, latencies of P3a and P3b and psychometric test results did not change significantly. These findings suggest that in cirrhotic patients without overt HE (i) impaired cognitive sensory function may occur in the absence of abnormalities of a standard psychometric test, the EEG, or VEPs, and (ii) increased latencies of P3a and P3b may constitute a component of subclinical HE, which is not mediated by increased brain levels of central benzodiazepine receptor agonist ligands.
A patient with gastroparesis is presented. Ultimately the diagnosis of paraneoplastic gastroparesis due to an occult small cell cancer of the lung was made. The difficulties in the diagnostic process and the pathogenesis of this very rare manifestation are discussed.
Introduction. Endoscopy of the colon and rectum is increasingly used. Aim of the Study. All consecutive endoscopies of the colon and rectum were studied in order to assess the yearly prevalence of significant endoscopic diagnoses. Methods. All consecutive endoscopies of the colon and rectum were included. Endoscopies were done with endoscopes of Olympus. Significant endoscopic diagnoses were defined as colorectal cancer, polyps, diverticuli, large sessile polyps, and inflammatory bowel disease. Results. In 20 years a total of 24431 endoscopies were done. The yearly number of sigmoidoscopies was mean 96, range of 42–370. The number of colonoscopies was mean 1126, range of 643–1912. The number of colonoscopies significantly increased. The number of colonoscopies on request of an internist or gastroenterologist showed a slow but steady increase. Successful caecal intubation rose from 70% to 92% in 2011. Since 1996 there is a steep increase in the percentage of procedures with abnormalities. The number of cancer and polyps increased in twenty years. No great changes were seen in inflammatory bowel disease. Conclusion. Colonoscopy is a procedure with a high diagnostic yield. The number of patients with tumours rose in twenty years.
(i) Optimal isolation of ERPs is critically dependent on stimulus contrast and electrode placement; (ii) ERPs appear to be more sensitive than primary sensory evoked potentials or the EEG in detecting impaired brain neuroelectrophysiological function; and (iii) Cirrhotic patients without overt encephalopathy in whom P3a and/or P3b latencies are prolonged may have subclinical hepatic encephalopathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
