Background: This study analyzed poorly understood relationship of two overlapping conditions: metabolic syndrome (MeS) and inflammatory bowel disease (IBD), both associated with inflammation in the visceral adipose tissue. Methods: Newly diagnosed 104 IBD patients, of which 50 Crohn's disease (CD) and 54 ulcerative colitis (UC), and 45 non-IBD controls were examined for MeS-related obesity and lipid markers. Th-17 immune genes IL17A, IL17F, IL23A, and TLR9 mRNAs were measured in intestinal mucosa by qRT-PCR. Subjects were genotyped for obesity-associated FTO variant rs9939609 by polymerase chain reaction–amplification refractory mutation system. Results: CD was associated with MeS (P = 0.01), while both CD and UC were associated with central obesity (P = 10−5, P = 0.002, respectively) and low levels of high-density lipoprotein (HDL) cholesterol (P = 5 × 10−6, P = 6 × 10−6, respectively). IBD lipid profile was characterized by decreased total and HDL cholesterol, while low-density lipoprotein cholesterol was reduced only in CD. Negative correlations were found between total cholesterol and CD activity index (P = 0.005), waist circumference and IL17A as well as IL17F mRNA levels in inflamed CD colon (P = 0.003, P = 0.001, respectively). Carriers of FTO rs9939609 AA genotype showed increased risk of CD (OR 2.6, P = 0.01). Conclusions: MeS, central obesity, and dyslipidemia could be important for IBD pathogenesis. This could influence therapeutic approaches and prevention strategies in high-risk groups.

Non-alcoholic fatty liver disease and colonic diverticulosis are widespread, obesity-related diseases. It hasrecently become clear that non-alcoholic fatty liver disease is a systemic disease and may play a key rolein metabolic syndrome; therefore, the term metabolic-dysfunction-associated fatty liver disease has beenintroduced in the literature. Excess visceral adipose tissue is an important predictor of complications in bothnon-alcoholic fatty liver disease and colonic diverticulosis. Current evidence suggests that intestinal dysbiosismay be involved in the development of both non-alcoholic fatty liver disease and colonic diverticulosis, andthat metabolic syndrome is a consequence rather than a cause of this complex relationship. In this review, ouraim was to assess the current knowledge of the complex interplay between metabolic syndrome, non-alcoholicfatty liver disease, and colonic diverticulosis.

Recently, there has been a growing interest in the application of artificial intelligence (AI) in medicine, especially in specialties where visualization methods are applied. AI is defined as a computer’s ability to achieve human cognitive performance, which is accomplished through enabling computer “learning”. This can be conducted in two ways, as machine learning and deep learning. Deep learning is a complex learning system involving the application of artificial neural networks, whose algorithms imitate the human form of learning. Upper gastrointestinal endoscopy allows examination of the esophagus, stomach and duodenum. In addition to the quality of endoscopic equipment and patient preparation, the performance of upper endoscopy depends on the experience and knowledge of the endoscopist. The application of artificial intelligence in endoscopy refers to computer-aided detection and the more complex computer-aided diagnosis. The application of AI in upper endoscopy is aimed at improving the detection of premalignant and malignant lesions, with special attention on the early detection of dysplasia in Barrett’s esophagus, the early detection of esophageal and stomach cancer and the detection of H. pylori infection. Artificial intelligence reduces the workload of endoscopists, is not influenced by human factors and increases the diagnostic accuracy and quality of endoscopic methods.

Background and Objectives: The aim of the study was to determine the association between presences of fatty pancreas (FP) with the features of metabolic syndrome (MeS) in patients with non–alcoholic fatty liver disease (NAFLD) and to establish a new noninvasive scoring system for the prediction of FP in patients with NAFLD. Material and Methods: 143 patients with NAFLD were classified according to FP severity grade into the two groups and evaluated for diagnostic criteria of MeS. All patients underwent sonographic examination with adiposity measurements and the liver biopsy. Liver fibrosis was evaluated semi-quantitatively according to the METAVIR scoring system and using non-invasive markers of hepatic fibrosis. Results: Waist circumference (WC) was predictive for increased risk of FP in NAFLD patients. Elevated fasting plasma glucose, total cholesterol, serum amylase and lipase levels were associated with presence of severe FP (p value = 0.052, p value = 0.007, p value = 0.014; p value = 0.024, respectively). Presence of increased amounts of mesenteric fat was associated with severe FP (p value = 0.013). The results of this study demonstrated highly significant association between NAFLD and presence of FP. The model for predicting the presence of FP was designed with probability value above 6.5. Conclusion: Pancreatic fat accumulation leads to worsening of pancreatic function which in turns exacerbates severity of metabolic syndrome associated with both, NAFLD and NAFPD.

Background: The increasing incidence of duodenal neoplasm has underlined different methods of resection depending on the clinical presentation, endoscopic features and histopathology. In this comprehensive review, we systematically describe the current knowledge concerning the diagnosis and management of duodenal adenomas (DAs) and discuss data considering all possible therapeutic approaches. Summary: Among a variety of duodenal lesions, including neuroendocrine tumors and gastrointestinal stromal tumors, DAs present precancerous lesions of the duodenal papilla or non-ampullary region necessitating removal. DAs can occur sporadically (SDA) as rare lesions or relatively common in polyposis syndromes. The endoscopic resections of DA are associated with an increased degree of complexity due to distinctive anatomical properties of the duodenal wall, luminal diameter and the presence of ampulla with pancreatic and biliary drainage. The endoscopic techniques including cold snare polypectomy (CSP), endoscopic mucosal resection (EMR), and argon plasma coagulation ablation are suggested to be less invasive than surgical treatment, associated with shorter hospital stay and lower cost. According to the current clinical practice, surgery has been accepted as standard therapeutic approach in familial adenomatous polyposis patients with severe polyposis or DA not amenable to endoscopic resection. Key Messages: The strategy for endoscopic resection of DAs depends on the lesion size, morphology, location, and histopathology findings. Small adenomas are most frequently diagnosed and removed by standard CSP techniques, while large laterally spreading lesions and ampullary adenoma are referred for EMR or endoscopic papillectomy respectively. Screening colonoscopy is indicated in patients with SDA. Additional studies for new endoscopic strategies and techniques for curative therapy of DAs are needed to refine future management decisions. Complete resection of DA is considered curative, but nevertheless, long-term endoscopic follow-up is still required to detect and treat any recurrent arising lesions.
