The clinical profile of patients with PSC in Singapore appears to differ with other published data, with a greater number presenting with hepatobiliary sepsis and less frequent association with IBD and pANCA. It is hypothesized that this may be related to differences in environmental triggers and genetic susceptibility.
In this paper, we aimed to provide professional guidance to practising gastrointestinal (GI) endoscopists for the safe conduct of GI endoscopy procedures during the current coronavirus disease 2019 (COVID-19) pandemic and future outbreaks of similar severe respiratory tract infections in Singapore. It draws on the lessons learnt during the severe acute respiratory syndrome (SARS) epidemic and available published data concerning the COVID-19 pandemic. It addresses measures before, during and after endoscopy that must be considered for both non-infected and infected patients, and provides recommendations for practical implementation.
Long-term biliary stenting is a feasible option for patients who decline or are medically unfit for further elective endoscopic or surgical procedures. Close follow-up is mandatory to detect and treat late complications.
Both H. pylori eradication and prokinetic therapy resulted in symptom improvement in two-thirds of dyspeptic patients at 1 year. More patients tended to achieve complete symptom relief with H. pylori eradication.
Stratification of H. pylori strains based on their potential for carcinogenesis, such as those strains that are seropositive for the 19.5 kDa antigen and seronegative for the 35-kDa antigen, may provide a basis for selective eradication of H. pylori infection and future vaccine development.
In this paper, we aim to provide professional guidance to clinicians who are managing patients with chronic liver disease during the current coronavirus disease 2019 (COVID-19) pandemic in Singapore. We reviewed and summarised the available relevant published data on liver disease in COVID-19 and the advisory statements that were issued by major professional bodies, such as the American Association for the Study of Liver Diseases and European Association for the Study of the Liver, contextualising the recommendations to our local situation.
When CT shows gastric wall thickening: (a) Nnormal upper endoscopy is strongly associated with normal EUS; (b) abnormal upper endoscopy is associated with abnormal EUS in 70% of cases; (c) clinical variables such as age, sex, and the presence of symptoms do not predict or increase the likelihood of abnormal EUS. Therefore, in patients with thickened gastric wall on CT, upper endoscopy should be used to select patients for EUS.
Background and aim: The role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis and staging of lung cancer is still not fully explored. This prospective study aimed to define the effectiveness of EUS-FNA as an adjunct to computer tomography (CT) and bronchoscopy in the evaluation of suspected lung cancer in routine clinical practice. Methods: Over a period of 20 weeks, the data of 16 consecutive patients suspected of lung cancer on account of respiratory symptoms, and/or the findings of either a mass or mediastinal lymph nodes on helical CT, who were referred for evaluation by EUS, were prospectively collected. Fourteen of these patients underwent sequential bronchoscopy followed by EUS-FNA in the same setting. Results: Bronchoscopy was performed in 15 patients, while EUS was performed in all 16 patients. Bronchoscopy diagnosed 9 cases of non-small-cell lung cancer (NSCLC) but was falsely negative in 3 cases of malignancies, which were all established by EUS-FNA of mediastinal lymph nodes (2 cases of NSCLC and 1 case of esophageal squamous cell cancer). EUS-FNA also diagnosed advanced NSCLC in another patient who did not undergo bronchoscopy, such that eventually 13 patients were diagnosed to have malignancies. Distant metastases were diagnosed by EUS-FNA in 4 cases of NSCLC (2 cases of left adrenal gland and 2 cases of pancreatic metastases). Two patients were diagnosed to have sarcoidosis and 1 patient was diagnosed to have pneumoconiosis eventually. Conclusions: EUS-FNA is useful as an adjunct to CT and bronchoscopy in the evaluation of suspected lung cancer.
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.
