Diagnostic approach to patients with suspected motility disorders: one size does not fit all.

Background: Dysphagia and retrosternal chest pain are considered typical manifestations of major esophageal motility disorders (mEMD). High-resolution manometry (HRM) is the gold standard for mEMD diagnosis, while endoscopy and barium swallow are ancillary tools. We aimed to investigate the frequency of mEMD among patients referred for HRM with typical compared to non-typical symptoms.

Patients with cardinal symptoms of eosinophilic esophagitis. Prejudice affects clinical practice….

Introduction: Dysphagia and bolus impaction are the cardinal manifestations of eosinophilic esophagitis (EoE). Esophageal biopsy sampling is mandatory for EoE diagnosis, data though suggest that clinician do not always obtain biopsies from patients with cardinal EoE symptoms during upper gastrointestinal endoscopy even if no other entity than EoE can explain patients symptoms. We aimed to search for the esophageal biopsy procurement rate as also for factors that drive clinicians to obtain esophageal biopsies among patients with cardinal EoE symptoms.

Incidence and risk factors of acute kidney injury in cirrhosis: a systematic review and meta-analysis of 5,202,232 outpatients, inpatients, and ICU-admitted patients.

Introduction: Acute kidney injury (AKI) is a commonly seen condition in the natural course of cirrhosis. The aim of this study was to evaluate the pooled incidence and risk factors of AKI in different clinical stages and situations in patients with cirrhosis.

Methods: Search was conducted on 13 December 2023 across MEDLINE (PubMed), Embase, and Cochrane databases.

Isolated nonspecific terminal ileitis: prevalence, clinical evolution and correlation with metachronous diagnosis of Crohn's disease: a retrospective study and review of the literature.

Background: The existing literature does not provide adequate guidance on the diagnosis and management of patients with nonspecific terminal ileitis, while data regarding the percentage of patients who ultimately develop Crohn's disease (CD) are scarce. We evaluated the prevalence and natural course of nonspecific terminal ileitis in patients who underwent colonoscopy during a 11-year period.

Methods: All patients with endoscopic findings of terminal ileitis and nonspecific histological findings were included.

Prevalence of cirrhotic cardiomyopathy according to different diagnostic criteria: alterations in ultrasonographic parameters of both left and right ventricles before and after stress.

Background: We estimated the frequency of cirrhotic cardiomyopathy (CCM) using all of the proposed diagnostic criteria, to describe the whole spectrum of cardiac alterations, and to investigate the role of stress in unmasking latent cases of CCM.

Methods: Ninety consecutive patients were recruited. CCM was evaluated using the Montreal, the American Society of Echocardiography 2009 criteria, and the 2019 modified criteria of the CCM consortium.

Sedation during endoscopic procedures: a Hellenic Society of Gastroenterology Position Statement.

Administration of sedation by non-anesthesiologists during gastrointestinal endoscopy remains highly controversial in Greece. The aim of this set of 16 position statements prepared by experts in the field on behalf of the Hellenic Society of Gastroenterology is to aid gastroenterologists in their everyday clinical practice and provide evidence for the best use of drugs for the sedation of patients who undergo an endoscopy. The statements address issues such as the level of sedation required, the best drugs used, their mode of action, their side-effects and possible ways to counter their action, and were adopted if at least 80% of all participants agreed upon them.

Efficacy of citalopram or amitriptyline versus no treatment in patients with functional chest pain.

Background: Functional chest pain (FCP) is characterized by the presence of chest pain of presumed esophageal origin, but with a negative workup on routine investigations, including ruling out gastroesophageal reflux disease (GERD). Antidepressants are frequently prescribed to treat FCP and are presumed to act as neuromodulators of visceral hypersensitivity. However, there is little evidence of their efficacy in patients with FCP.

Endoscopic diagnosis and management of esophagogastric variceal hemorrhage: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

1: ESGE recommends that patients with compensated advanced chronic liver disease (ACLD; due to viruses, alcohol, and/or nonobese [BMI < 30 kg/m] nonalcoholic steatohepatitis) and clinically significant portal hypertension (hepatic venous pressure gradient [HVPG] > 10 mmHg and/or liver stiffness by transient elastography > 25 kPa) should receive, if no contraindications, nonselective beta blocker (NSBB) therapy (preferably carvedilol) to prevent the development of variceal bleeding.Strong recommendation, moderate quality evidence. 2: ESGE recommends that in those patients unable to receive NSBB therapy with a screening upper gastrointestinal (GI) endoscopy that demonstrates high risk esophageal varices, endoscopic band ligation (EBL) is the endoscopic prophylactic treatment of choice.

The Lyon Consensus Criteria for GERD Diagnosis in a Greek Population: The Clinical Impact and Changes in GERD Diagnosis in a Real-World, Retrospective Study.

(1) Introduction/aim: Gastroesophageal reflux disease (GERD) affects 8−33% globally. The gold standard examination technique in diagnosing GERD is 24 h pHmetry ± impedance. Recently, new diagnostic criteria were introduced by the Lyon Consensus for GERD diagnosis.

Comparing 2D-shear wave to transient elastography for the evaluation of liver fibrosis in nonalcoholic fatty liver disease.

Background And Aim: The aim of this study is to evaluate the performance of 2D-shear wave elastography (2D-SWE) in patients with nonalcoholic fatty liver disease (NAFLD) and compare it to transient elastography.

Methods: Over 6 months, 552 patients with NAFLD underwent liver stiffness measurement (LSM) by both 2D-SWE and transient elastography with controlled attenuation parameter (CAP) at the same visit.

Results: LSM was not feasible by transient elastography (M/XL probe) in 18 (3.

Serum zonulin levels in patients with liver cirrhosis: Prognostic implications.

Background: Increased gut permeability and bacterial translocation play an important role in liver cirrhosis. Zonulin is a recently recognized protein involved in the disintegration of the intestinal barrier.

Aim: To investigate possible differences in serum zonulin levels among patients with different cirrhosis stages and their potential prognostic implications.

Comparative Utility of Transient and 2D Shear Wave Elastography for the Assessment of Liver Fibrosis in Clinical Practice.

The aim of the study was to investigate the feasibility and correlation of liver stiffness measurements (LSM) between 2D-shear wave elastography (2D-SWE) and transient elastography (TE) in patients with chronic liver disease. Over 4 months, 421 patients with chronic liver disease of any cause underwent LSM by 2D-SWE and TE (M and/or XL probe) and controlled attenuation parameter at the same visit. LSM was not feasible by TE in 16 (3.

Keratin 7 expression in hepatic cholestatic diseases.

We evaluated keratin 7 (K7) hepatocellular expression in 92 patients with common types of acute and chronic cholestatic diseases caused by bile duct obstruction/destruction or parenchymal lesions [acute hepatitis (n=20), mixed/pure cholestasis (n=16), primary biliary cholangitis-PBC (n=35), primary sclerosing cholangitis-PSC (n=10), vanishing bile duct syndrome (n=3), complete large bile duct obstruction due to space-occupying lesions (n=8)]. K7 immunohistochemical hepatocellular expression and ductular reaction (DR) were semi-quantitatively assessed. Results were correlated with liver enzyme serum levels, cholestasis type, histological features, hepatocellular Ki67 labelling index (LI) and HepPar1 expression.

Assessment of dietary habits and the adequacy of dietary intake of patients with cirrhosis-the KIRRHOS study.

Background & Aims: Undernutrition is widely prevalent in patients with cirrhosis and affects prognosis. Given the lack of data regarding the dietary intake (DI) and habits of patients with cirrhosis, the aim of the present study was to evaluate them by assessing diet's adequacy compared to the new guidelines, and the association of DI with nutritional status indicators.

Methods: One hundred and eighty-seven patients (57.

Predictive performance of newer Asian hepatocellular carcinoma risk scores in treated Caucasians with chronic hepatitis B.

Background & Aims: Recently, several risk scores for prediction of hepatocellular carcinoma (HCC) were developed in cohorts of treated Asian patients with chronic hepatitis B (CHB), but they have not been assessed in non-Asian patients. We evaluated the predictability and comparative utility of our PAGE-B and recent Asian HCC risk scores in nucleos(t)ide analogue (NA)-treated adult Caucasian patients with CHB, with or without well-documented compensated cirrhosis but not previous diagnosis of HCC.

Methods: We included 1,951 patients treated with entecavir/tenofovir and followed up for a median of 7.

Platelet activation and hypercoagulability in patients with early primary biliary cholangitis compared with healthy controls.

Background: Patients with primary biliary cholangitis (PBC) who have advanced disease are hypercoagulable, with no thrombophilic factors compared to non-cholestatic cirrhotics. We investigated whether hypercoagulability is present in early-stage PBC.

Methods: PBC patients with biopsy-documented early disease and healthy controls matched by sex and age were asked to participate in the study.

Differences between fellows and fellowship program directors in their perception of the impact of the COVID-19 pandemic on gastroenterology training: results from a nationwide survey in Greece.

Background: Lockdown measures applied during the SARS-CoV-2 outbreak caused a significant disturbance to hospital routine. We assessed trainees' and fellowship directors' perceptions regarding the impact of the pandemic on gastroenterology fellowship training.

Methods: A web-based survey was anonymously disseminated to all Greek gastroenterology fellows and fellowship program directors.

Similar risk of hepatocellular carcinoma during long-term entecavir or tenofovir therapy in Caucasian patients with chronic hepatitis B.

Background & Aims: A recent study in Asian patients with chronic hepatitis B (CHB) reported that the incidence of hepatocellular carcinoma (HCC) was lower in patients treated with tenofovir disoproxil fumarate (TDF) than entecavir (ETV), but this finding remains controversial. We aimed to identify any differences in HCC incidence, or other patient outcomes, between patients receiving TDF or ETV in the well monitored, multicenter European PAGE-B cohort.

Methods: We included 1,935 Caucasians with CHB, with or without compensated cirrhosis, treated with ETV (n = 772) or TDF (n = 1,163) monotherapy.

New epidemiology of hepatitis delta.

Hepatitis D virus (HDV) is a defective pathogen that needs hepatitis B virus (HBV) for infection. Co-infection of HBsAg-positive individuals with HDV is commonly associated with a more rapid progression to cirrhosis, a higher incidence of hepatocellular carcinoma (HCC) and increased mortality. Initial studies have shown that about 5% of chronic HBV carriers worldwide (15-20 millions) were also infected with HDV.

Hepatocellular carcinoma prediction beyond year 5 of oral therapy in a large cohort of Caucasian patients with chronic hepatitis B.

Background & Aims: Hepatocellular carcinoma (HCC) may develop in patients with chronic hepatitis (CHB) even after 5 years of oral therapy and cannot be easily predicted. We assessed predictors of HCC development and the need for HCC surveillance in this setting.

Methods: Of 1,951 adult Caucasians with CHB included in the PAGE-B cohort, 1,427 (73%) had completed >5 years of follow-up under therapy without developing HCC by year 5.

High prevalence of asymptomatic peptic ulcers diagnosed during screening endoscopy in patients with cirrhosis.

Background: Peptic ulcer disease (PUD) is more prevalent in cirrhotics and this may aggravate prognosis. We investigated the prevalence of PUD in cirrhotics and its potential association with () infection, the underlying etiology and severity of liver disease, and other manifestations of portal hypertension (PH).

Methods: We enrolled consecutive asymptomatic cirrhotic patients who underwent screening endoscopy in a tertiary hospital during a 12-month period.
