Background and Aim: The aim of the present study was to examine the etiology of hepatocellular carcinoma (HCC) by underlying cause and determine the characteristics and clinical features of patients with HCC., Materials and Methods: The study comprised 1802 HCC patients diagnosed and followed up by Liver Diseases Outpatient Clinics in 14 tertiary centers in Turkey between 2001 and 2020., Results: The mean age was 62.3±10.7 years, and 78% of them were males. Of the patients, 82% had cirrhosis. Hepatitis B virus (HBV) infection was the most common etiology (54%), followed by hepatitis C virus (HCV) infection (19%) and nonalcoholic fatty liver disease (NAFLD) (10%). Of the patients, 56% had a single lesion. Macrovascular invasion and extrahepatic spread were present in 15% and 12% of the patients, respectively. The median serum alpha-fetoprotein level was 25.4 ng/mL. In total, 39% of the patients fulfilled the Milan Criteria. When we compared the characteristics of patients diagnosed before and after January 2016, the proportion of NAFLD-related HCC cases increased after 2016, from 6.6% to 13.4%., Conclusion: Chronic HBV and HCV infections remain the main causes of HCC in Turkey. The importance of NAFLD as a cause of HCC is increasing., Competing Interests: The authors have no conflict of interest to declare., (© Copyright 2022 by Hepatology Forum.)

Objectives: The aim of the study was to evaluate the relationship among lower esophageal sphincter pressure (LESP), Helicobacter pylori (Hp), and gastroesophageal reflux (GER)., Methods: The retrospective study included patients with isolated hypertensive or hypotensive lower esophageal sphincter (LES) who underwent esophageal manometry in our gastroenterology motility laboratory and had normal manometry results. Demographic characteristics, complaints on admission, upper endoscopy findings, 24-h esophageal pH monitoring results, and presence of Hp in gastric biopsy were evaluated., Results: A total of 1226 patients were included in the study, among whom women comprised 54% of all patients. Mean age was 45.4±13.4 years. Most common presenting complaint was pyrosis (85.4%). Pathological reflux was detected in 61.4% of the patients in 24-h esophageal pH monitoring. Reflux esophagitis was detected in 22.9% and LES laxity was present in 17.4% of the patients. In gastric biopsy, Hp was positive in 40% of the patients. The age of patients with hypertensive LES was significantly higher and female gender and body mass index (BMI) were associated with hypertensive LES. Pyrosis was significantly less prevalent in patients with hypertensive LESP. Esophagitis and LES laxity were significantly more prevalent in patients with hypotensive LES. No significant difference was found among the three groups with regard to reflux and Hp positivity. No significant difference was found between Hp-positive and Hp-negative groups with regard to reflux and reflux esophagitis., Conclusion: No clear relationship was found among LES disorders, GER, and Hp. Moreover, no significant difference was found among LES disorders with regard to GER, while the presence of hypotensive LESP, rather than Hp, was found to be an important factor in the development of reflux esophagitis., Competing Interests: None declared., (© Copyright 2022 by The Medical Bulletin of Sisli Etfal Hospital.)

Aim: The aim of this study was to investigate the incidence, risk factors, and treatment strategies of proximally migrated pancreatic stents., Materials and Methods: The data of 626 sessions of 421 patients with pancreatic duct stenting were retrospectively analyzed between 2010 and 2018, and patients with proximally migrated stents were included in the study., Results: Of 626 stents examined, 77 migrated proximally (12%). The migration rate (MR) was 16%, 2%, and 7%, respectively, in patients treated with chronic pancreatitis, malignancy, and pancreatic leakage indication. The MR was 14% in procedures with pancreatic duct stenosis, 21% in procedures with pancreatic sphincterotomy, and 27% in procedures performed from minor papillae. The MR of the 5, 7, and 10 Fr stents was 4%, 17%, and 10%, respectively. Of the 77 migrated stents, 64 were successfully removed (83%). This success rate (SR) was 84% in procedures with chronic pancreatitis indication, 83% in procedures with pancreatic duct stenosis, 79% in procedures with sphincterotomy, and 75% in procedures performed from minor papillae. The SR of the 5, 7, and 10 Fr stents was 100%, 79%, and 92%, respectively. It was also determined that 33 stents were fractured and migrated (43%). The SR of the fractured stents was 76%. Moreover, of the stents that were successfully removed, 35 were removed with forceps (55%) and 15 (23%) were removed with a balloon. Furthermore, in 47 cases, the stent was removed in the first session (73%). Acute pancreatitis occurred in 5 patients (8%) and perforation occurred in 1 patient (2%)., Conclusion: In this study, it was shown that proximal migration of pancreatic stents is frequent and most of these stents can be removed successfully., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Arrhythmias and electrocardiographic changes are reported in several noncardiac diseases, including liver cirrhosis (LC). We intended to evaluate the interval from the peak to the end of the electrocardiographic T wave (Tp-e), Tp-e/QTc ratio, and fQRS as presumed markers of arrhythmias in LC., Methods: In this cross-sectional study, a total of 88 consecutive patients with LC according to clinical, biological, ultrasonographic, or histological criteria and 73 control subjects were enrolled. The severity of cirrhosis was classified according to Pugh-Child's classification and Model for End-Stage Liver Disease (MELD) score. Tp-e interval, Tp-e/QTc ratio, and fQRS rates were measured from the 12-lead electrocardiogram., Results: Tp-e interval, Tp-e/QTc ratio and fQRS rates were significantly increased in parallel to the severity of LC (P < 0.001, P < 0.001, and P = 0.003, respectively). In correlation analysis, Pugh-Child stage showed a significantly positive correlation with Tp-e interval (r = 0.462, P < 0.001), QTc interval (r = 0.373, P < 0.001), Tp-e/QTc ratio (r = 0.352, P < 0.001), and fQRS (r = 0.407, P < 0.001). Furthermore, Tp-e interval (r = 0.414, P < 0.001) and Tp-e/QTc ratio (r = 0.426, P< 0.001) had significant positive correlation with MELD score., Conclusions: Our study demonstrated that Tp-e interval, Tp-e/QTc ratios, and fQRS rates were significantly increased in parallel to the severity of LC. Thus, these findings may implicate that Tp-e interval, Tp-e/QTc ratio, and fQRS may be novel and useful indicators for prediction of arrhythmias in LC., (© 2016 Wiley Periodicals, Inc.)
