Background/Aims: Pancreatic exocrine insufficiency (PEI) is a prevalent disease that is often underdiagnosed and undertreated, leading to resulting in diminished health-related quality of life. The PEI questionnaire (PEI-Q), a patient-reported outcome questionnaire developed to diagnose and evaluate PEI, is available only in English. The study aimed to provide a Turkish translation of PEI-Q and validate its reliability and diagnostic performance in a Turkish-speaking population with PEI. Materials and Methods: This study included 161 participants: 98 patients with PEI and 63 healthy controls. Participants underwent the PEI-Q test, and the results were statistically analyzed for reliability and validity. The diagnostic value of PEI-Q was determined using receiver operating characteristic (ROC) curves. Cronbach’s alpha was used to assess internal consistency, while exploratory factor analysis was performed to determine construct validity and reveal the factor structure. Results: The mean age of participants was 45.0 years, and 60.2% were male. Participants with PEI were significantly older than those without. Scores for abdominal, bowel movement, and total symptoms were significantly higher in patients with PEI than in controls. ROC analysis revealed good diagnostic value for PEI-Q, with areas under the curve ranging from 0.798 to 0.851 for different symptom scores. Cronbach’s alpha coefficients were above 0.70, indicating good internal consistency, and exploratory factor analysis supported a 4-factor structure, accounting for 68.9% of the total variance. Conclusion: The Turkish version of the PEI-Q is a reliable, easy-to-use, and valid screening tool for diagnosing PEI. It consistently assesses symptoms and quality of life in patients with PEI, helping to inform diagnosis and treatment.

Background/Aims: This study aimed to evaluate the diagnostic efficacy of cell block (CB) and liquid-based cytology (LBC) for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in pancreatic tumors. Materials and Methods: The study included patients who underwent EUS-FNA for pancreatic tumors between January 2015 and February 2021 and whose cytology samples were both processed for LBC and CB. Results: Data of 390 patients (220 men, mean age: 64.2 ± 11.4 years) were retrospectively analyzed. Of the detected lesions (size: 17-120 mm; mean: 39.9 ± 13.9 mm), 220 (56.4%) were located in the head and uncinate process of the pancreas. Lesions in 339 (86.9%) patients were diagnosed as malignant using CB and/or LBC and suspicious for malignancy in 44 (11.3%) patients. In 7 patients with non-diagnostic (6 cases) or negative for malignancy (1 case) EUS-FNA results using both methods, the diagnosis of malignancy was established via ultrasound-guided percutaneous biopsy. Malignancy was detected in 324 (92.4%), 313 (87.9%), and 298 (87.9%) patients using CB, LBC, and both CB and LBC, respectively. Final diagnosis was obtained in 339 (98%) patients by using CB and/or LBC. The combined use of the both methods exhibited significantly superior diagnostic accuracy compared with CB and LBC alone (P < .001). Conclusion: Liquid-based cytology and CB exhibit high diagnostic accuracy for the detection of pancreatic tumors in patients undergoing EUS-FNA. The combined use of both methods showed a significantly higher diagnostic accuracy than LBC and CB alone.

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.

Introduction: Data on the relationship between Coronavirus disease-2019 (COVID-19) and acute pancreatitis are limited. This study aimed to investigate the possible role of COVID-19 in the etiology of acute pancreatitis in a tertiary-care educational university hospital by retrospectively evaluating the incidence of acute pancreatitis in adult hospitalized patients with COVID-19. Materials and Methods: Severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) polymerase chain reaction (PCR)-positive adult inpatients from March 15, 2020, to February 1, 2021, constituted the study group in our hospital. This cohort was analyzed for acute pancreatitis criteria, including acute abdominal pain, increased amylase and/or lipase more than three times the normal value, and radiological finding supporting the disease. Patients who met at least two of the acute pancreatitis diagnostic criteria were determined, and those who met the criteria during or after SARS-CoV-2 PCR positivity detection were included in the study. These patients were further analyzed for COVID-19-related data and pancreatitis severity status. Results: Our hospital had 1227 inpatients with COVID-19 diagnosis in one year. A total of four cases met the inclusion criteria. Acute pancreatitis rates were detected at 0.3% and 1.07% for all cohorts (n=1227) and the pancreatic enzyme-tested group (n=372), respectively. Of these four patients, two (50%) were females (50%) and the mean age was 70.7 (range: 64-79) years. There was no correlation between COVID-19 pneumonia and pancreatitis severity scores, including Ranson, Acute Physiologic Assessment and Chronic Health Evaluation 2, and modified computed tomography severity scores. Conclusion: COVID-19 is a rare risk factor for acute pancreatitis and did not affect the pancreatitis severity or mortality in our cohort.
