PWE-139 Further Validation of Terminal Peptide of Procollagen Iii (PIIINP) for the Detection and Assessment of Nonalcoholic Steatohepatitis in Patien…
2013
Introduction PIIINP has recently been shown to discriminate between simple steatosis (SS) and NASH both in patients without advanced fibrosis and in patients with all degrees of fibrosis 1 . In this study we validated PIIINP as a biomarker of NASH in a cohort of patients with biopsy proven NAFLD and evaluated its performance at the proposed diagnostic thresholds. Methods 71 patients with NAFLD and no evidence of other liver disease were included in this study. Liver biopsies were performed on all patients and analysed by a expert liver histopathologist. All liver biopsies were of suitable size for analysis (> 12mm and > 5 portal tracts) and classified in a dichotomous manner into those with…
Impact of Non-Alcoholic Fatty Liver Disease on Metabolic Comorbidities in Type 2 Diabetes Mellitus.
2021
Abstract Objective Type 2 Diabetes (T2D) is a major risk factor for the development and progression of non-alcoholic fatty liver disease (NAFLD). The published prevelance in epidemiological studies in this high risk population exceeds 70%. The aim of this analysis was to investigate the impact of NAFLD on T2D patients in Germany. Methods Using the Disease Analyzer Database (IQVIA), T2D patients with NAFLD diagnosed in Germany were matched to a cohort without NAFLD controlling for age, sex, physician, index year and metabolic comorbidities and assessed for their risk of developing myocardial infarction, stroke, peripheral arterial disease (PAD) or chronic kidney disease, as well as the type …
Molecular endoscopic imaging: the future is bright
2019
The prediction and final survival rate of gastrointestinal cancers are dependent on the stage of disease. The ideal would be to detect those gastrointestinal lesions at early stage or even premalignant forms which are difficult to detect by conventional endoscopy with white light optical imaging as they show minimum or no changes in morphological characteristics and are thus left untreated. The introduction of molecular imaging has greatly changed the pattern for detecting gastrointestinal lesions from purely macroscopic structural imaging to the molecular level. It allows microscopic examination of the gastrointestinal mucosa with endoscopy after the topical or systemic application of mol…
Sentinel Lymph Node Analysis in Colorectal Cancer Patients Using One-Step Nucleic Acid Amplification in Combination With Fluorescence and Indocyanine…
2018
Purpose: Analysis of the sentinel lymph node (SLN) in colorectal cancer (CRC) patients was proposed for more accurate staging and tailored lymphadenectomy. The aim of this study was to assess the ability to predict lymph node (LN) involvement through analysis of the SLN with a one-step nucleic acid (OSNA) technique in combination with peritumoral injection of indocyanine green (ICG) and near-infrared (NIR) lymphangiography in CRC patients. Methods: A total of 34 patients were enrolled. Overall, 51 LNs were analyzed with OSNA. LNs of 17 patients (50%) were examined simultaneously with hematoxylin and eosin (H&E) and OSNA. Results: SLN analysis of 17 patients examined with H&E and OSN…
Intradiverticular Ampulla of Vater: Personal Experience at ERCP
2013
Introduction. Conflicting results have been reported about the true impact of intradiverticula ampulla (IA) on the technical success and complication rate of endoscopic retrograde cholangiopancreatography (ERCP). Patients. A total of 500 patients who underwent ERCP were divided into two groups according to the presence (group A, 81 patients) or absence (group B, 419 patients) of IA. Success rate, difficulty at cannulation, findings at ERCP, and procedure-related complications were retrospectively reviewed. Results. Successful cannulation was achieved in 100% of group A patients compared to 98% of group B patients (P = ns). There was a significant difference in the type of cannulation that w…
Surveillance colonoscopy in ulcerative colitis: magnifying chromoendoscopy in the spotlight
2004
Chromoendoscopy in ulcerative colitis may offer the possibility of detecting dysplastic or neoplastic changes at a curable stage, and thus expand the indication for chromoendoscopy from screening to surveillance colonoscopy Colonoscopy is the gold standard for colorectal cancer screening.1–3 Detection and complete removal of adenomas disrupt the adenoma-carcinoma sequence and thus prevent the development of colorectal cancer. However, endoscopists still fear that they may have overlooked relevant lesions despite the availability of modern videoendoscopes. This problem is underlined by a relatively high rate of adenomas missed by conventional endoscopy (up to 27%), as determined by back to b…
Conventional Radiology in the Evaluation of the Small Bowel
2015
For many years, the small bowel has been considered as the “black box” of the gastrointestinal system because it could not be evaluated through endoscopy. For this reason, the conventional radiological methods, such as small bowel enteroclysis and small bowel follow-through, have been considered the standard approach for the evaluation of the small bowel in the diagnosis and management of Crohn’s disease for years. However, due to technological limits, the study of small bowel through conventional radiology has been focused mainly on its function than on its anatomy. To date, the conventional examination with the study of intestinal transit is now rarely used, if not obsolete, but it has st…
Colorectal Polyps
2008
Publisher Summary Colorectal cancer (CRC) remains the second leading cause of cancer death for both women and men with more than 130,000 newly diagnosed cases and 50,000 deaths each year in the United States alone. Most colon cancers develop from nonmalignant colonic adenomas or polyps over a comparatively long time period ranging between 24 and 60 months. Reflecting this adenomatous pathogenesis of most colorectal cancers, polyp screening with subsequent polypectomy is used to constitute an effective approach for decreasing the incidence of this malignant tumor. Thus, colorectal screening for polyps may be considered one of the most promising preventive measures in medicine. Most available…
Dolichomegaösophagus bei Achalasie
2004
HISTORY AND CLINICAL FINDINGS A 78-year-old woman suffered from achalasia since 63 years with a progressive decompensation over the last year. 53 years ago, treatment with the Stark Dilator and 24 years ago, pneumatic dilation had been carried out. Currently, the patient presented with dysphagia for liquid and solid food, with permanent retrosternal pain and regurgitation for every meal, leading to a weight loss of 10 kg. INVESTIGATIONS The barium esophagogram showed a marked dilation of the esophagus with retinated secretions and food. The cardia had a maximum width of 15 mm. On endoscopy, reflux esophagitis and an insufficient lower esophageal sphincter were evident. TREATMENT AND COURSE …
Der hyperplastische Polyp des Magens - eine Präkanzerose?
2002
In general, hyperplastic polyps of the stomach are regarded as benign lesions. Still there is the chance to find carcinomas within them as documented in this case report. This finding can be interpreted as an incidental appearance. At the moment there are no standardized guidelines regarding diagnostics and therapy of gastric hyperplastic polyps. Referring to a short review of the literature endoscopic snare polypectomy seems to be a reasonable therapeutic option of hyperplastic polyps with a size of 0.5-1 cm. Although it is possible to determine the histology by forceps biopsy, it is possible to be misled by missing areas of focal carcinomas. Complications after polypectomy are rare and of…
