1Mediastinal node staging by positron emission tomographycomputed tomography and selective endoscopic ultrasound with fine needle aspiration for patients with upper gastrointestinal cancer:Results from a regional centre显示文摘AIM To investigate the impact of endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA) and positron emission tomography-computed tomography(PET-CT) in the nodal staging of upper gastrointestinal(GI) cancer in a tertiary referral centre.METHODS We performed a retrospective review of prospectively recorded data held on all patients with a diagnosis of upper GI cancer made between January 2009 and December 2015. Only those patients who had both a PET-CT and EUS with FNA sampling of a mediastinal node distant from the primary tumour were included. Using a positive EUS-FNA result as the gold standard for lymph node involvement, the sensitivity, specificity, positive and negative predictive values(PPV and NPV) and accuracy of PET-CT in the staging of mediastinal lymph nodes were calculated. The impact on therapeutic strategy of adding EUS-FNA to PET-CT was assessed.RESULTS One hundred and twenty one patients were included. Sixty nine patients had a diagnosis of oesophageal adenocarcinoma(Thirty one of whom were junctional), forty eight had oesophageal squamous cell carcinoma and four had gastric adenocarcinoma. The FNA results were inadequate in eleven cases and the PET-CT findings were indeterminate in two cases, therefore thirteen patients(10.7%) were excluded from further analysis. There was concordance between PET-CT and EUS-FNA findings in seventy one of the remaining one hundred and eight patients(65.7%). The sensitivity, specificity, PPV and NPV values of PET-CT were 92.5%, 50%, 52.1% and 91.9% respectively. There was discordance between PET-CT and EUS-FNA findings in thirty seven out of one hundred and eight patients(34.3%). MDT discussion led to a radical treatment pathway in twenty seven of these cases, after the final tumour stage was altered as a direct consequence of the EUS-FNA findings. Of these patients, fourteen(51.9%) experienced clinical remission of a median of nine months(range three to forty two months). CONCLUSION EUS-FNA leads to altered staging of upper GI cancer, resulting in more patients receiving radical treatment that would have been the case using PET-CT staging alone.Chris Harrington Lyn Smith Jennifer Bisland Elisabet López González Neil Jamieson Stuart Paterson Adrian John Stanley 2018World Journal of Gastrointestinal Endoscopy2018,10,1:4
2Utility of faecal calprotectin analysis in adult inflammatory bowel disease显示文摘The inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis, are chronic relapsing, remitting disorders. Diagnosis, along with assessment of disease activity and prognosis present challenges to managing clinicians. Faecal biomarkers, such as faecal calprotectin, are a non-invasive method which can be used to aid these decisions. Calprotectin is a calcium and zinc binding protein found in the cytosol of human neutrophils and macrophages. It is released extracellularly in times of cell stress or damage and can be detected within faeces and thus can be used as a sensitive marker of intestinal inflammation. Faecal calprotectin has been shown to be useful in the diagnosis of IBD, correlates with mucosal disease activity and can help to predict response to treatment or relapse. With growing evidence supporting its use, over the last decade this faecal biomarker has significantly changed the way IBD is managed.Lyn A Smith Daniel R Gaya 2012World Journal of Gastroenterology2012,18,46:3
3Catastrophic gastrointestinal complication of systemic immunosuppression显示文摘We present a case of acute upper gastrointestinal haemorrhage in a patient with systemic vasculitis immunosuppressed on cyclophosphamide and prednisolone.The patient presented with a diffuse haemorrhagic oesophagitis and a non-specific duodenitis.Biopsies taken from the oesophagus and duodenum demonstrated infection with herpes simplex virus(HSV)and cytomegalovirus(CMV)respectively.Viral infection of the upper gastrointestinal tract is a recognised complication of immunosuppression and HSV is one of the most common pathogens.CMV on the other hand most commonly causes a colitis or less commonly oesophagitis.CMV enteritis is rare as is the synchronous infection with two viral agents in an immunocompromised patient having being described in a few case series only.Viral infection of the gastrointestinal tract in immunocompromised patients should be treated with systemic anti-viral medication and consideration to withdrawal of the immunosuppressive therapy if possible and appropriate.The authors highlight the need for a high suspicion of viral infection in immunosuppressed patients presenting with upper gastrointestinal bleeding.Lyn Alexandra Smith Mitali Gangopadhyay Daniel R Gaya 2015World Journal of Gastroenterology2015,21,8:2
