BACKGROUND: Tissue acquisition from a thickened gastric wall using biopsy forceps may not always lead to diagnosis, given the submucosal location of the pathology. Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) may serve as a minimally invasive diagnostic tool in such cases. Hence, we aimed to assess the diagnostic outcome and safety of EUS-TA from thickened gastric walls. METHODS: Data from patients with gastric wall thickening undergoing EUS-TA at 5 tertiary care centers from August 2020 to August 2022 were retrospectively analyzed...

BACKGROUND: Steroids are an important pharmacologic treatment in patients with eosinophilic esophagitis (EoE). Fluticasone and budesonide are the 2 main steroid medications used in EOE treatment, but current United States (US) guidelines do not recommend one agent over the other. In this study, we conducted a meta-analysis to compare important patient outcomes when both agents are used. METHODS: A comprehensive search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was performed from each database's inception to March 29th , 2023...

BACKGROUND: Gastroesophageal reflux disease (GERD) has a complex pathophysiology and a heterogeneous symptom profile. The brain-esophageal axis in GERD has been studied with functional brain imaging during the last decades, but data from obese patients was just recently reported. A comparison of such a group with non-obese subjects is lacking in the literature. This study aimed to evaluate heartburn perception and brain connectivity responses during esophageal acid stimulation in subjects with and without obesity, controlling for the presence of typical reflux symptoms...

BACKGROUND: Add-on devices with projections, e.g., Endocuff, Endocuff Vision, EndoRings, and Wingcap, placed on the distal tip of the colonoscope promise to improve the detection of precancerous lesions. We performed a meta-analysis to evaluate the performance of these devices exclusively among individuals undergoing colonoscopy for screening purpose. METHODS: A computerized literature search was performed across MEDLINE and Cochrane Library databases for randomized controlled trials that compared standard colonoscopy (SC) to procedures using add-on devices...

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. A dobutamine stress test was also performed...

BACKGROUND: Multidisciplinary team (MDT) meetings aim to optimize patient management. We evaluated the impact of MDT discussions on the management and diagnosis of focal pancreatic lesions in a single tertiary center. METHODS: All patients with an initial diagnosis of solid or cystic pancreatic lesion discussed in our institution's MDT meeting on pancreatic diseases between January 1, 2020, and December 31, 2021, were included. The impact of MDT discussion on patient management, defined as a modification of the initially proposed therapeutic plan after MDT discussion, as well as the criteria leading to this modification, were the primary outcomes...

BACKGROUND: A new subcutaneous (SC) formulation exists for infliximab (CT-P13 SC). The aim of this study was to assess the durability of clinical and endoscopic responses after a switch from intravenous (IV) to SC infliximab. METHODS: Patients were transitioned on maintenance infliximab, including those with dose-optimized therapy. The primary outcome was clinical, biochemical and overall remission at 6 months, as defined by a Harvey-Bradshaw Index <5 for Crohn's disease or a partial Mayo score <3 for ulcerative colitis, C-reactive protein less than 10 mg/L, and fecal calprotectin less than 100 μg/g...

The introduction of biliary plastic stents has been a landmark achievement in the field of endoscopic retrograde cholangiopancreatography, ensuring minimally invasive and highly effective relief of the obstructed biliary system. Attempts to improve the patency and avoid complications after biliary plastic stenting have led to several innovations, but complications due to stent occlusion are still frequent. Because these complications are clinically relevant, and may guide stent choice and patient management, efforts have been made to elucidate the causes of and ways to prevent occlusion of indwelling stents...

BACKGROUND: The incidence of pediatric-onset inflammatory bowel disease (IBD) is rising, while the relapsing and often severe nature of IBD, and its impact on emotional and pubertal development and social maturation underline the need for a successful transition from pediatric to adult care. METHODS: A web-based survey was distributed via the Hellenic Group for the Study of IBD, the Hellenic Society of Gastroenterology Department of North Greece, and the Hellenic Society of Pediatric Gastroenterology, Hepatology, and Nutrition...

BACKGROUND: Acute cholangitis (AC) is an infection of the biliary tract superimposed on stasis. This study aimed to investigate the effects of smoking on inpatient outcomes of AC. METHODS: We identified primary AC hospitalizations using the National Inpatient Sample database (2017-2020). Using a 1:1 matching method, we created a matched comparison cohort of AC patients who were non-smokers, based on demographics, hospital characteristics and comorbidities. RESULTS: We matched 3960 smoker patients with 3960 non-smoker patients within the AC population...

BACKGROUND: Research within the last decade highlights the patients' frailty status as an important predictor of esophageal cancer outcomes, but the literature evaluating frailty's role in these patients remains limited. We evaluated the role of frailty in patients undergoing resection of malignant esophageal neoplasms. METHODS: We used the Nationwide Readmissions Database from 2016 and 2017 to identify patients who underwent excision of a malignant esophageal neoplasm...

BACKGROUND: Type 2 diabetes (T2DM) can accelerate the progression of cirrhosis. The potential for oral diabetes medications to counteract the mortality and morbidity of chronic liver diseases is unclear. METHODS: We compared the effectiveness of dual metformin and glucagon-like peptide-1 receptor agonists (GLP1-RA) vs. metformin treatment alone in reducing mortality and hepatic complications in cirrhotic patients with T2DM. We evaluated propensity score-matched cohorts of T2DM and cirrhosis patients treated with metformin or dual metformin and GLP1-RA therapy...

BACKGROUND: Lumen-apposing metal stents (LAMS) are an evolving option for the management of benign gastrointestinal (GI) strictures. Multiple studies have reported on the efficacy and safety of LAMS for benign GI strictures, but were limited by their small sample size. Hence, we conducted this meta-analysis to assess the critical role of LAMS for the management of benign GI strictures. METHODS: A literature search of various databases from inception until October 2022 was conducted for studies evaluating the outcome of LAMS in patients with benign GI strictures...

Endoscopic radiofrequency ablation (RFA) has emerged as a minimally invasive treatment option in cases of malignant biliary obstruction, pancreatic cancer, and other pancreatic cystic neoplasms. Intraductal biliary RFA is safe, effective, and confers a survival advantage over stenting alone, where it should be used an adjunct to biliary stenting. Endoscopic ultrasound-guided RFA can also provide pancreatic cyst resolution in patients who are not ideal operative candidates. The aim of this review is to describe the endoscopic applications and associated outcomes of RFA...

The COVID-19 outbreak has had severe consequences for global public health, medical communities, and the socioeconomic status of a considerable number of countries. The emergence of COVID-19 has also significantly impacted the world of liver transplantation (LT). Studies from transplantation centers around the world have shown that LTs during the COVID-19 pandemic have been restricted because of the high risk of serious COVID-19 infection in this population. According to the Centers for Disease Control and Prevention, patients with liver disease are considered at higher risk for severe COVID-19 infection...

BACKGROUND: Anorectal function deteriorates with age. The diagnostic performance of the endoscopic pressure study integrated system (EPSIS), an endoscopic carbon dioxide (CO2 ) insufflation stress test of the lower esophageal sphincter has been previously evaluated as a diagnostic tool for gastroesophageal reflux disease. We aimed to evaluate the applicability of EPSIS in improving anorectal function. We hypothesized that EPSIS can be applied to the diagnosis of lower gastrointestinal tract disorders...

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is performed to treat biliary complications after a liver transplantation; however, the previously available literature on the safety of ERCP in liver transplant patients is limited. We aimed to study the safety of ERCP in liver transplant patients. METHODS: We used a National Inpatient Sample database from 2016-2019 to identify patients who underwent ERCP and had a history of a liver transplantation, using the international classification of diseases, 10th revision...

One of the primary methods by which the gut microbiome interacts with its host is through the interactions that occur through the production of the metabolites produced, either directly, or indirectly, through microbial metabolism. Decades of research has demonstrated that these metabolic products play a vital role in human health, either for its benefit or detriment. This review article highlights the main metabolites produced by the interactions between diet and the gut microbiome, bile acids and the gut microbiome, and products produced by the gut microbiome alone...

There are no established standards for the diagnosis of Clostridioides difficile infection (CDI), even though the importance of this infection in humans is well known. The effectiveness of the commercially available techniques, which are all standardized for use with human feces, is also limited in terms of the accuracy of the tests. Furthermore, the current approach lacks a point-of-care diagnosis with an acceptable range of sensitivity and specificity. This article reviews the challenges and possible future solutions for the detection of CDI in adults...
