Article Synopsis
  • Severe alcohol-associated hepatitis (SAH) has a high mortality rate, particularly in patients who don't respond to corticosteroid treatment, with 70%-80% dying within 6 months.
  • A study conducted from January 2016 to November 2023 found that patients treated with granulocyte colony-stimulating factor (G-CSF) showed significantly better 90-day overall survival rates compared to those receiving standard medical therapy or corticosteroids.
  • The G-CSF group also experienced lower rates of gastrointestinal bleeding and better long-term survival without the need for a transplant, highlighting its potential as a treatment option for SAH.

Goals And Background: Nonalcoholic steatohepatitis (NASH) is a leading cause of cirrhosis. We aim to explore the clinical outcomes of NASH cirrhosis compared with other etiologies of cirrhosis.

Methods: We utilized an EHR-based database (TriNetX) to study the outcomes of NASH cirrhosis.

Objectives: Although splanchnic vein thrombosis (SVT) is a well-known local complication of acute pancreatitis, extrasplanchnic venous thromboembolism (ESVT) is inadequately studied. Here, we aim to explore the incidence of venous thromboembolism (VTE) in acute necrotizing pancreatitis (ANP) and the associated mortality.

Methods: Adults with a diagnosis of ANP from January 2017 to December 2022 were identified using appropriate International Classification of Diseases, 10th Revision, Clinical Modification codes.

Introduction: Endoscopic ultrasound-guided biliary drainage (EUS-BD) is an alternative to endoscopic retrograde cholangiopancreatography (ERCP)-guided transpapillary drainage in malignant distal biliary obstruction (MDBO). This meta-analysis of randomized controlled trials (RCTs) aims to compare the outcomes of these 2 approaches.

Methods: Electronic databases from January 2005 through December 2023 were searched for RCTs comparing outcomes of EUS-BD and ERCP for treating MDBO.

The advantages of endoscopic submucosal dissection (ESD) over endoscopic mucosal resection for large colorectal neoplasms are well established; however, the technical challenges and lack of adequate training in ESD limit its widespread adoption in Western countries. A literature search was performed in Medline, Embase, Web of Science, and the Cochrane Library for studies conducted in non-Asian countries evaluating the effectiveness of colorectal ESD. A random effects model was used to obtain pooled en bloc, R0 resection rates, and adverse events (AEs).

Objectives: Endoscopic papillectomy (EP) is a minimally invasive therapy for the management of ampullary adenomas (AA). We conducted this multicenter study to assess the incidence of and factors related to the recurrence of AA after EP in patients with familial adenomatous polyposis (FAP) compared to sporadic AA.

Methods: We included patients who underwent EP for AA at 10 tertiary hospitals.

Background And Aims: Real-world data on the adverse events and the survival benefit of Barrett's endoscopic therapy (BET) are limited. The aim of this study was to examine the safety and effectiveness (survival benefit) of BET in patients with neoplastic Barrett's esophagus (BE).

Methods: An electronic health record-based database (TriNetX) was used to select patients with BE with dysplasia and esophageal adenocarcinoma (EAC) from 2016 to 2020.

The prevalence of pancreatic cysts has been rising due to the widespread use of cross-sectional imaging (CT scan and MRI) of the abdomen. While most pancreatic cysts are benign and do not require treatment or surveillance, a significant minority are premalignant and rarely malignant. The risk stratification of these lesions is not straightforward, and individual risk assessment, cyst size, distribution, and alarming morphologic features (when present) can guide the next steps in management.

Background And Objectives: High mortality in pancreas ductal adenocarcinoma (PDAC) is related to delayed diagnosis and lack of cost-effective early detection strategies. Retrospective studies have demonstrated an association between PDAC and acute pancreatitis (AP). Herein, we explore the incidence of PDAC in patients with non-biliary and non-alcoholic AP.

In the modern era of high-quality cross-sectional imaging, pancreatic cysts (PCs) are a common finding. The prevalence of incidental PCs detected on cross-sectional abdominal imaging (such as CT scan) is 3%-14% which increases with age, up to 8% in those 70 years or older. Although PCs can be precursors of future pancreatic adenocarcinoma, imaging modalities such as CT scan, MRI, or endoscopic ultrasound with fine-needle aspiration (EUS-FNA) are suboptimal at risk stratifying the malignant potential of individual cysts.

Background: Gastroparesis is a debilitating condition that may impact morbidity and mortality, but there is a lack of long-term studies examining this relation. The aim of this study was to determine the predictors of mortality in gastroparesis and to determine the nutritional deficiencies.

Methods: Between September 30, 2009 and January 31, 2020, we identified 320 patients (mean age 47.

Goal: We aim to perform a multicenter retrospective cohort study to determine if elevated serum lipase determines clinical outcomes in patients with coronavirus disease 2019 (COVID-19).

Background: Several cases of acute pancreatitis (AP) have recently been reported in association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Most of the evidence is based on elevated serum lipase values without objective demonstration of pancreatic inflammation or necrosis.

Goal: The goal of this study was to study the incidence of fungal infection in necrotizing pancreatitis (NP) and its impact on mortality.

Background: Infected pancreatic necrosis is a major contributor to morbidity and mortality in patients with NP. While pancreatic fungal infection (PFI) has frequently been identified in patients with NP, its effect on the clinical outcomes is unclear.

Pancreatic ductal adenocarcinoma (PDAC) is typically diagnosed at an advanced stage, with systemic therapy being the mainstay of treatment. Survival continues to be limited, typically less than 1 year. The PDAC microenvironment is characterized by a paucity of malignant epithelial cells, abundant stroma with predominantly immunosuppressive T cells and myelosuppressive-type macrophages (M2), and hypovascularity.

Context: Pancreatic cancer (PDAC) is one of the most challenging cancers to treat with modest recent improvements in survival from new systemic therapies. There is growing interest in individualized therapy underpinned by somatic and germline genomic alterations.

Objective: A systematic review of data on therapies targeting somatic and germline alterations, and their downstream pathways in PDAC.

The endoscopic management armamentarium of gastrointestinal disruptions including perforations, leaks, and fistulas has slowly but steadily broadened in recent years. Previously limited to surgical or conservative medical management, innovations in advanced endoscopic techniques like natural orifice transluminal endoscopic surgery (NOTES) have paved the path towards development of endoscopic closure techniques. Early recognition of a gastrointestinal defect is the most important independent variable in determining successful endoscopic closure and patient outcome.
