Öğe Acute pancreatitis in Turkey: Results of a nationwide multicenter study(Elsevier, 2024) Koksal, Aydin Seref; Tozlu, Mukaddes; Sezgin, Orhan; Oguz, Dilek; Kalkan, Ismail Hakk; Altntas, Engin; Yaras, SerkanBackground: Acute pancreatitis (AP) is the most common gastrointestinal disease requiring hospitalization, with significant mortality and morbidity. We aimed to evaluate the clinical characteristics of AP and physicians ' compliance with international guidelines during its management. Methods: All patients with AP who were hospitalized at 17 tertiary centers in Turkey between April and October 2022 were evaluated in a prospective cohort study. Patients with insufficient data, COVID-19 and those aged below 18 years were excluded. The definitions were based on the 2012 revised Atlanta criteria. Results: The study included 2144 patients (median age:58, 52 % female). The most common etiologies were biliary (n = 1438, 67.1 %), idiopathic (n = 259, 12 %), hypertriglyceridemia (n = 128, 6 %) and alcohol (n = 90, 4.2 %). Disease severity was mild in 1567 (73.1 %), moderate in 521 (24.3 %), and severe in 58 (2.6 %) patients. Morphology was necrotizing in 4.7 % of the patients. The overall mortality rate was 1.6 %. PASS and BISAP had the highest accuracy in predicting severe pancreatitis on admission (AUC:0.85 and 0.81, respectively). CT was performed in 61 % of the patients, with the majority (90 %) being within 72 h after admission. Prophylactic NSAIDs were not administered in 44 % of the patients with post-ERCP pancreatitis (n = 86). Antibiotics were administered to 53.7 % of the patients, and 38 % of those received them prophylactically. Conclusions: This prospective study provides an extensive report on clinical characteristics, management and outcomes of AP in real -world practice. Mortality remains high in severe cases and physicians ' adherence to guidelines during management of the disease needs improvement in some aspects. (c) 2023 IAP and EPC. Published by Elsevier B.V.

We conducted a case-control study in order to evaluate whether gastric xanthelasma is an indicator of advanced atrophic gastritis and intestinal metaplasia. The study was conducted among 1400 patients who underwent elective upper endoscopy. Patients with gastric xanthelasma and atrophy and/or intestinal metaplasia constituted the study group (n = 55). The control group involved patients with only atrophic gastritis and/or intestinal metaplasia (n = 50). Histopathologic findings of the groups including the distribution of atrophic gastritis and/or intestinal metaplasia, operative link on gastritis assessment score, operative link on gastritis intestinal metaplasia assessment (OLGIM) score, and presence of dysplasia and malignancy were compared. Subgroup analysis was performed in order to establish the relation between the characteristics (size, number, and localization) of xanthelasmas, atrophy, and intestinal metaplasia. Multifocal atrophic gastritis was significantly more common in patients with a gastric xanthelasma (41.8 vs. 26.0 %, p = 0.03). Patients with multiple xanthelasmas had a significantly higher rate of intestinal metaplasia (p = 0.02) and a higher OLGIM score (p = 0.02) compared to those with a single xanthelasma. Dysplasia was detected in 8 (14.5 %) patients with a xanthelasma and 4 (8.0 %) patients without a xanthelasma (p = 0.2). Gastric xanthelasma(s) is a warning endoscopic sign for the presence of multifocal atrophic gastritis and advanced intestinal metaplasia.Öğe Prevalence of Pancreatic Steatosis and Its Associated Factors in Turkey: A Nation-Wide Multicenter Study(Aves, 2024) Sezgin, Orhan; Yaras, Serkan; Cindoruk, Mehmet; Kasap, Elmas; Unal, Hakan; Koksal, Aydin Seref; Yildirim, Abdullah EmreBackground/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.Öğe RAPIDLY RECURRING GASTRIC POLYP AFTER ENDOSCOPIC POLYPECTOMY(Lippincott Williams & Wilkins, 2015) Koksal, Aydin Seref; Kalkan, Ismail Hakki; Yildiz, Hakan…Öğe A simple method to improve adenoma detection rate during colonoscopy: Altering patient position(Pulsus Group Inc, 2013) Koksal, Aydin Seref; Kalkan, Ismail Hakki; Torun, Serkan; Taskiran, Ismail; Oztas, Erkin; Kayacetin, Ertugrul; Sasmaz, NurgulBACKGROUND: Colonoscopy is currently considered to be the gold standard method for detecting and removing adenomatous polyps. However, tandem colonoscopy studies reveal a pooled polyp miss rate of 22%. OBJECTIVE: A prospective randomized trial was conducted to assess whether alteration of patient position during colonoscopy withdrawal increases the adenoma detection rate (ADR). METHOD: The study group included 120 patients who presented for elective colonoscopic examination. After reaching the cecum, patients were randomly assigned in a 1: 1 ratio to examination in either the left lateral position or other positions (left lateral position for the cecum, ascending colon and hepatic flexure; supine for transverse colon; and supine and right lateral position for splenic flexure, descending and sigmoid colon) first. Examination of the colon was performed segment by segment. The size, morphology and location of all polyps were recorded. Polyps were removed immediately after examination of a colon segment when all positions were completed. ADR and polyp detection rates (PDR) were calculated. RESULTS: A total of 102 patients completed the study. Examination in the left lateral position revealed 66 polyps in 31 patients (PDR 30.3%) and 42 adenomas in 24 patients (ADR 23.5%). PDR increased to 43.1% (81 polyps in 44 patients) and the ADR to 33.3% (53 adenomas in 34 patients) after the colon was examined in the additional positions (P< 0.001 and P= 0.002, respectively). The increase in the number of adenomas detected was statistically significant in the transverse and sigmoid colon. The addition of position changes led to a 9.8% increase in the ADR in the transverse colon, splenic flexure, and descending and sigmoid colon. The frequency of surveillance interval was shortened in nine (8.8%) patients after examination of the colon in dynamic positions. CONCLUSION: Alteration of patient position during colonoscopy withdrawal is a simple and effective method to improve ADR.
