Publication Metadata only BOUGIE DILATATION IN BENIGN ESOPHAGEAL STRICTURES: EVALUATION OF ADJUVANT METHYLPREDNISOLONE INJECTION(2022-05-01T00:00:00Z) KÖKER, İBRAHİM HAKKI; ŞENTÜRK, HAKAN; KÖKER, İBRAHİM HAKKI; ŞENTÜRK, HAKANObjective: Mechanical dilatation and adjuvant injection of tri-amcinolone acetate (TA) effectively preserve the opening pro-vided and reduce the number of bougie dilation (BD) in benign esophageal strictures. In this study, we aimed to evaluate the role of Methylprednisolone (MP) injection after BD in providing permanent/long-term lumen opening.Publication Metadata only Comparison of LMA® Gastro™ airway and gastrolaryngeal tube in endoscopic retrograde cholangiopancreatography: a prospective randomized observational trial(2021-05-13T00:00:00Z) Uysal, Harun; Senturk, HAKAN; Calim, Muhittin; Daskaya, Hayrettin; Guney, Ibrahim A; Karaaslan, Kazim; UYSAL, HARUN; ŞENTÜRK, HAKAN; DAŞKAYA, HAYRETTİNBackground: New generation airway devices with different designs have been developed as an alternative to endotracheal intubation in order to avoid adverse events associated with sedation in endoscopic procedures and to provide patent airway. We aimed to compare two supraglottic airway devices (SGADs), the LMA® Gastro™ airway and gastrolaryngeal tube (GLT), in terms of airway efficiency, performance during procedure and adverse events in endoscopic retrograde cholangiopancreatography (ERCP). Methods: A hundred-three ERCP patients without high risk of aspiration were included. Patients were randomly allocated to the LMA Gastro and GLT groups. The primary study outcomes were the comparison of the two SGADs in terms of oropharyngeal leak pressure (OLP). Secondary study outcome was SGADs-related adverse events. Results: Procedures were completed with SGADs in fifty patients in each group. The rate of successful insertion at first attempt was 72% in GLT and 96% in LMA Gastro (P=0.004). The mean OLP of LMA Gastro Group (31.8 cmH2O) was significantly higher than that of the GLT Group (26.5 cmH2O), (P=0.0001). However, endoscopists' satisfaction was higher in GLT (P=0.0001). Mucosal damage and sore throat were lower in LMA Gastro Group. Conclusions: LMA® Gastro™ had a higher OLP than GLT. However, GLT was better for endoscopist satisfaction, as it provides more satisfying maneuverability. As to secondary outcome advers events were lower in LMA® Gastro™. The lower complication rates associated with the device and providing a more patent airway also highlighted the apparent clinical efficacy of LMA® Gastro™ than GLT, in ERCP.Publication Metadata only Effect of pre-operative red blood cell distribution on cancer stage and morbidity rate in patients with pancreatic cancer.(2014-09-15T00:00:00Z) ŞENTÜRK, H; YILMAZ, A; Malya, FATMA ÜMİT; OZTURK, G; CITGEZ, B; OZDENKAYA, Y; ERSAVAS, C; AGAN, A; KARATEPE, O; MALYA, FATMA ÜMİT; ŞENTÜRK, HAKANPublication Metadata only Early prediction of the severe course, survival, and ICU requirements in acute pancreatitis by artificial intelligence(2023-01-01) İnce A. T.; Silahtaroğlu G.; Seven G.; Koçhan K.; Yıldız K.; Şentürk H.; İNCE, ALİ TÜZÜN; SEVEN, GÜLSEREN; KOÇHAN, KORAY; ŞENTÜRK, HAKANAbstractObjectiveTo evaluate the success of artificial intelligence for early prediction of severe course, survival, and intensive care unit(ICU) requirement in patients with acute pancreatitis(AP).MethodsRetrospectively, 1334 patients were included the study. Severity is determined according to the Revised Atlanta Classification(RAC). The success of machine learning(ML) method was evaluated by 13 simple demographic, clinical, etiologic, and laboratory features obtained on ER admission. Additionally, it was evaluated whether Balthazar-computerized tomography severity index(CTSI) at 48-h contributed to success. The dataset was split into two parts, 90% for ML(of which 70% for learning and 30% for testing) and 10% for validation and 5-fold stratified sampling has been utilized. Variable Importance was used in the selection of features during training phase of machine. The Gradient Boost Algorithm trained the machine by KNIME analytics platform. SMOTE has been applied to increase the minority classes for training. The combined effects of the measured features were examined by multivariate logistic regression analysis and reciever operating curve curves of the prediction and confidence of the target variables were obtained.ResultsAccuracy values for the early estimation of Atlanta severity score, ICU requirement, and survival were found as 88.20%, 98.25%, and 92.77% respectively. When Balthazar-CTSI score is used, results were found as 91.02%, 92.25%, and 98% respectively.ConclusionsThe ML method we used successfully predicted the severe course, ICU requirement and survival, with promising accuracy values of over 88%. If 48-h Balthazar-CTSI is included in the calculation, the severity score and survival rates increase even more.Publication Metadata only The clinical feature and outcome of groove pancreatitis in a cohort: A single center experience with review of the literature(2022-08-01T00:00:00Z) DEĞER, KAMURAN CUMHUR; KÖKER, İBRAHİM HAKKI; Destek, Sabahattin; TOPRAK, HÜSEYİN; Yapalak, Yunus; GÖNÜLTAŞ, CEREN; ŞENTÜRK, HAKAN; DEĞER, KAMURAN CUMHUR; KÖKER, İBRAHİM HAKKI; TOPRAK, HÜSEYİN; GÖNÜLTAŞ, CEREN; ŞENTÜRK, HAKANBACKGROUND: Groove pancreatitis (GP) is a rare form of chronic pancreatitis that is less common and is now gaining awareness with multimodal imaging modalities. Our aim is to analyze the mid-long term outcomes of patients diagnosed with GP with different treatment approaches.Publication Metadata only Routinely evaluated clinical assays and laboratory tests [real test] and fibrosis stages of chronic hepatitis B and C(2014-10-01T00:00:00Z) Bugdaci, Mehmet Sait; KORKMAZ, HÜSEYİN; Demir, Ali; BIYIK, MURAT; Temel, Tuncer; GÖKTÜRK, HÜSEYİN SAVAŞ; Ozakyol, Aysegul; HATEMİ, Ali İbrahim; Baysal, Birol; Karaca, Cetin; ŞENTÜRK, HAKAN; ŞENTÜRK, HAKANBackground/Aims: To provide a new mathematical formula to predict liver fibrosis in patients with chronic viral hepatitis.Publication Metadata only A Rare Cause of Acute Pancreatitis - Annular Pancreas: A Case Report(2015-12-01) KAYAR Y.; YİĞİT M.; EKİNCİ İ.; ATAY M.; ŞENTÜRK H.; EKİNCİ, İSKENDER; ŞENTÜRK, HAKANPublication Metadata only Gastric myoelectrical activity abnormalities of electrogastrography in patients with functional dyspepsia(2016-09-01T00:00:00Z) Kayar, Yusuf; Danalioglu, Ahmet; Al Kafee, Abdullah; Okkesim, Sukru; ŞENTÜRK, HAKAN; ŞENTÜRK, HAKANBackground/Aims: Pathogenesis of functional dyspepsia (FD) is unclear and not well documented. Some gastric motility abnormalities have been reported to be important factors. Transcutaneous electrogastrography (EGG) is an experimental method that is used to assess FD. We aimed to compare FD patients with control subjects in terms of motility abnormalities according to the EGG results.Publication Metadata only Comparison of the optimized direct spectrophotometric serum prolidase enzyme activity assay method with the currently used spectrophotometric assay methods and liver fibrosis indexes to distinguish the early stages of liver fibrosis in patients with chronic hepatitis B infection(2023-04-01) Kayadibi H.; Köker I. H.; Şentürk H.; Merzifonlu S. C.; İnce A. T.; ŞENTÜRK, HAKAN; İNCE, ALİ TÜZÜNPublication Metadata only EUS-guided FNA of a portal vein thrombus in hepatocellular carcinoma(2015-06-01T00:00:00Z) Kayar, Yusuf; Turkdogan, Kenan Ahmet; Baysal, Birol; ÜNVER, NURCAN; Danalioglu, Ahmet; ŞENTÜRK, HAKAN; ÜNVER, NURCAN; ŞENTÜRK, HAKANPortal vein thrombosis is a relatively rare but well-known complication of cirrhosis that has a prevalence of between 1% and 5.7%. On the contrary, in case of hepatocellular carcinoma (HCC), it is a much more frequent complication. In this paper, we presented three cases that had liver cirrhosis, mass and portal vein thrombosis in liver. We were not able to diagnose the cases through imaging methods, laboratory results or histopathologically, however, they were diagnosed with endoscopic ultrasonography-fine needle aspiration EUS-FNA from portal vein thrombus.
