Although endoscopic ultrasound (EUS) guided celiac neurolysis (CN) is mostly a safer procedure than the percutaneous posterior approach, severe complications such as paraplegia have been reported.Publication Metadata only Patient selection bias and inappropriate stent selection leading to false conclusions in the comparison of metal and plastic stents(2016-01-01T00:00:00Z) Koker, Ibrahim Hakki; KÖKER, İBRAHİM HAKKIPublication Metadata only The Role of Serum Cytokines in the Pathogenesis of Hepatic Osteodystrophy in Male Cirrhotic Patients(2012-01-01T00:00:00Z) Soylu, Ali Riza; Tuglu, Cengiz; Arikan, Ender; Yetisyigit, Tarkan; Kunduracilar, Hakan; Koker, Ibrahim Hakki; Unsal, Gulbin; Tezel, Ahmet Huseyin; Umit, Hasan; Berkarda, Sakir; KÖKER, İBRAHİM HAKKIObjective. In this study, we aimed to investigate the possible role of serum cytokines in the development of hepatic osteodystrophy. Matherial and Methods. 44 consecutive male cirrhotic patients (17 alcoholic, 20 hepatitis B, 7 hepatitis C), 15 age- and sex-matched chronic alcoholics without liver disease, and 17 age- and sex-matched healthy controls were included in the study during one year period. Bone mineral density was measured by dual X-ray absorptiometry in the lumbar vertebrate and femoral neck. Serum interleukin levels were measured by ELISA method. Results. Although osteopenia frequency between our cirrhotic patients was 20%, there was no difference in T-scores among the controls and other groups. Serum interleukin-1, interleukin-8, and tumor necrosis factor-alpha levels were not different between all groups. Serum interleukin-2 and interleukin-6 levels were higher in the cirrhotics than controls (P < 0.001). However, there were no significant difference between osteopenic and nonosteopenic cirrhotics. Conclusion. According to the results of the study in this small population of 44 male cirrhotic patients, frequency of hepatic osteopenia is small and serum interleukins 1, 2, 6, 8, and tumor necrosis factor-alpha may not play a role in the pathogenesis of hepatic osteodystrophy. Further studies in which large number of patients involved are necessary in this field.Publication Metadata only Prognostic value of increased B type natriuretic peptide in cases with acute pancreatitis(2012-06-01T00:00:00Z) Bugdaci, Mehmet Sait; Oztekin, Erkan; Kara, Ekrem; Koker, Ibrahim; Tufan, Ayhan; KÖKER, İBRAHİM HAKKIBackground: Acute pancreatitis (AP) is a systemic disease with a rising incidence. Cardiac dysfunction may occur as an early complication of AP. B type natriuretic factor (BNP) is a diagnostic and prognostic indicator of cardiac disorders. Therefore, in this study we aimed to assess the relationship between serum BNP concentrations and severity of AP.Publication Metadata only Importance of ascites adenosine deaminase in diagnosing abdominal tuberculosis with ascites(2015-07-01T00:00:00Z) Koker, Ibrahim Hakki; KÖKER, İBRAHİM HAKKIPublication Metadata only The relationship between serum histon levels and the severity of acute pancreatitits(2019-05-01) biberci keskin, elmas; Sümbül Gültepe, Bilge; Köker, ibrahim Hakkı; Şentürk, HAKAN; BİBERCİ KESKİN, ELMAS; İNCE, ALİ TÜZÜN; KÖKER, İBRAHİM HAKKI; ŞENTÜRK, HAKANPublication Metadata only The role of plasma exchange in hypertriglyceridemia-induced acute pancreatitis(2019-06-01T00:00:00Z) Koçhan, K; Şentürk, H; Köker, İH; Gülen, B; İnce, ALİ TÜZÜN; BİBERCİ KESKİN, ELMAS; KOÇHAN, KORAY; KÖKER, İBRAHİM HAKKI; İNCE, ALİ TÜZÜN; ŞENTÜRK, HAKANBackground Hypertriglyceridemia (HTG)-induced acute pancreatitis (AP) leads to higher morbidity and mortality compared with other etiologies. The role of plasma exchange (PE) in this context is still not well established. We aimed to assess the clinical outcomes of patients with HTG-induced AP who underwent PE and compare it with those who did not. Patients and methods We retrospectively evaluated the data of patients who were admitted with HTG-induced AP between January 2013 and May 2018. The endpoint of the study was to assess the clinical outcomes, which included complication rates, mortality, and pancreatitis recurrence rate. Results Overall, 41 patients were included in the final analysis. Of these, 12 (29.2%) underwent PE. Patients undergoing PE had more severe pancreatitis on the basis of the Japanese Severity Score [10 (83.3%) vs. 14 (48.3%), P=0.03, respectively). Although mortality was higher in patients who underwent PE [three (25.0%) vs. zero, P<0.01, respectively], there was no difference in terms of complications and recurrence rates. Over a median 21 months of follow-up, 11 (26.8%) patients had recurrent AP. Conclusion Although PE effectively reduced plasma triglyceride levels, there was no decrease in mortality or recurrences.Publication Metadata only The largest colorectal polyp cohort study in Turkey: Should more details be evaluated?(2014-10-01T00:00:00Z) Koker, Ibrahim Hakki; KÖKER, İBRAHİM HAKKI
