Background/Aims: Esophageal variceal bleeding (EVB) is an important cause of mortality and morbidity in liver cirrhosis. In this study, we aimed to predict the possibility of EVB in patients with cirrhosis using a non-invasive score.Methods: A total of 359 patients with cirrhosis were divided into two groups based on the presence or absence of EVB. ChildTurcotte-Pugh (CTP) score, a model for end-stage liver disease, aspartate aminotransferase to alanine aminotransferase ratio, aspartate aminotransferase to platelet ratio index (APRI), fibrosis-4-index (FIB-4), aspartate aminotransferase to alanine aminotransferase ratio/platelet ratio index (AARPRI), and S-index were measured for all participants. Receiver operating characteristic curves were obtained for all parameters, and the optimal cut-off value was determined in predicting EVB.Results: In patients with EVB, the number of platelets (PLT) were low (p<0.001) and APRI, AARPRI, FIB-4, and S-index were significantly higher than those in patients without EBV. APRI, AARPRI, FIB-4, PLT, and S-index were statistically significant predictors of EVB (p<0.05).Conclusions: FIB-4 and AARPRI, which are non-invasive markers of fibrosis, can be used to predict EVB. In addition, the 66.5 109/L cut-off value for PLT is important for EVB.

Acute pancreatitis (AP) is a clinical condition that arises acutely in the pancreas through various inflammatory pathways due to multiple causes. Turkish Society of Gastroenterology Pancreas Working Group developed comprehensive guidance statements regarding the management of AP that include its epidemiology, etiology, clinical presentation, diagnostic criteria, disease severity, treatment, prognosis, local and systemic complications. The statements were developed through literature review, deliberation, and consensus opinion. These statements were ultimately used to develop a conceptual framework for the multidisciplinary management of AP. Cite this article as: Öğütmen Koç D, Bengi G, Gül Ö, et al.

Background/Aims: Pancreatic steatosis (PS) is a pathology associated with metabolic syndrome (MS), endocrin and exocrine disfunctions of the pancreas, and fatty liver. The data on the frequency of PS are very limited. We aimed to evaluate the frequency of PS detected by transabdominal ultrasonography (TAU) in gastroenterology clinics located in different geographical regions of Turkey and the factors associated with it. Materials and Methods: Volunteers were evaluated by TAU for PS and hepatosteatosis (HS), and its degree. Pancreatic stiffness was evaluated by ultrasonographic shear wave elastography (SWE). All demographic, physical, and biochemical parametres were measured. Results: A total of 1700 volunteers from 14 centers throughout Turkey were included in the study. Mean age was 48.03 +- 20.86 years (56.9% female). Prevalance of PS was detected in 68.9%. In the PS group, age, body mass index (BMI), waist circumference, systolic blood pressure, fasting blood glucose (FBG), lipid levels, insulin resistance, diabetes mellitus, hypertension, MS frequency, and pancreatic SWE score were increasing, and fecal elastase level was decreasing in correlation with the degree of PS. The frequency of HS was 55.5%. Hepatosteatosis [odds ratio (OR): 9.472], increased age (OR: 1.02), and BMI (OR: 1.089) were independent risk factors for the occurrence of PS. Lean-PS rate was 11.8%. The lean-PS group was predominantly female and younger than non-lean PS. Also it has lower blood pressure, FBG, liver enzymes, lipid levels, and HS rates. Conclusion: The frequency of PS was found 68.9% in Turkey. Its relationship was determined with age, BMI, HS, MS (and its components), pancreatic stiffness, and fecal elastase level.

Background and aims: Chronic viral hepatitis (CVH) has a spectrum from asymptomatic disease to cirrhosis and hepatocellular carcinoma. In our study, we aimed to establish the relations between disease stage, illness perception, coping strategies and psychological morbidity in CVH. Methods: A total of 182 patients with chronic hepatitis B (CHB) (n = 136) and chronic hepatitis C (CHC) (n = 46) were enrolled. Illness perceptions were measured with the Brief Illness Perceptions Questionnaire. Coping strategies were measured with the Carver Brief Coping Questionnaire. Anxiety and depression were measured with the Hospital Anxiety and Depression Scale. Relations were evaluated by structural equation modeling (SEM). Results: In CHB, combining the questionnaire data using SEM resulted in a final model with an excellent fit [χ ² (2) = 0.00, P = 1.000, χ ²/N = 0.00, root mean square error of approximation (RMSEA) < 0.001, comparative fit index (CFI) = 1.000, goodness-of-fit index (GFI) = 1.000]. Disease stage had a significant direct influence on illness perceptions (β = 0.23, P = 0.006). Illness perceptions had a significant direct influence on emotional coping strategy, depression and anxiety (β = 0.20, P = 0.019; β = 0.33, P < 0.001; β = 0.59, P < 0.001, respectively). While the use of emotional coping strategies was associated significantly (P = 0.01) with the presence of anxiety, problem-focused coping strategy was associated with depression (P = 0.004). In CHC, SEM resulted in a final model with an excellent fit [χ ² (2) = 0.078, P = 0.962, χ ²/N = 0.039, RMSEA 0.05). Illness perceptions had a significant direct influence on depression and anxiety (β = 0.27, P = 0.023; β = 0.44, P < 0.001, respectively). Conclusion: The psychological consequences of the disease vary depending on the person’s perception of illness and coping strategies.

Background and Aim: The histological diagnosis of autoimmune hepatitis (AIH) is challenging. A new consensus recommendation was provided by the International AIH Pathology Group to address the problems in the histological diagnosis. The purpose of this study is to compare the 2008 ‘simplified’ criteria for AIH with the ‘consensus recommendation’ of 2022 in terms of diagnostic sensitivity. Materials and Methods: A retrospective analysis was conducted on pathological specimens of patients diagnosed with Autoimmune Hepatitis (AIH) between 2010 and 2022. Out of 188 patients enlisted, 88 were selected based on exclusion criteria. The specimens were examined by two experienced hepatopathologists and a resident pathologist. All specimens were analyzed using both the “simplified” criteria and the new consensus recommendations. Results: Out of a total of 78 patients, the 2022 consensus recommendations raised the diagnostic category of 16 patients (20.5%) to a higher level. Six patients who were previously diagnosed as “atypical” were now considered “possible AIH”, while 10 patients with a “compatible” diagnosis were elevated to “likely AIH” category. No patients were found to fall into a lower diagnostic category according to the new recommendations. A significant difference in diagnostic sensitivity was observed between the 2008 criteria and the 2022 consensus report (p
