Background: Per-oral endoscopic myotomy (POEM) is a rapidly emerging minimally invasive procedure for management of achalasia. Same-day discharge after POEM is safe and feasible; however, some patients may need hospitalization. We aimed to identify characteristics and outcomes for achalasia patients requiring hospitalizations after POEM in the United States (US).

Background: Several small studies reported high risk of progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) patients who undergo solid organ transplantation (SOT) and implied that this may be due to immunosuppressant use. However, the major shortcoming of these studies was the lack of a control population. Therefore, we aimed to determine the rates of neoplastic progression in BE patients who underwent SOT and compare to that in controls and identify the predictors of progression.

Background: Peptic ulcer disease (PUD) is frequently seen in patients with liver cirrhosis. However, current literature lacks data on PUD in non-alcoholic fatty liver disease (NAFLD) hospitalizations.

Aim: To identify trends and clinical outcomes of PUD in NAFLD hospitalizations in the United States.

Background: Portal vein thrombosis (PVT) is a rare complication of acute pancreatitis (AP) and might be associated with worse outcomes. We aimed to study trends, outcomes, and predictors of PVT in AP patients.

Methods: The National Inpatient Sample database was utilized to identify the adult patients (≥ 18 years) with primary diagnosis of AP from 2004 to 2013 using International Classification of Disease, Ninth Revision.

Background: The prognostic and pathophysiologic significance of the biliary microbiota in pancreaticobiliary malignancies is little understood. Our goal was to find malignancy-related microbiomic fingerprints in bile samples taken from patients with benign and malignant pancreaticobiliary diseases.

Methods: Bile specimens were collected from consenting patients during routine endoscopic retrograde cholangiopancreatography.

Background/aims: Colonic volvulus (CV), a common cause of bowel obstruction, often requires intervention. We aimed to identify hospitalization trends and CV outcomes in the United States.

Methods: We used the National Inpatient Sample to identify all adult CV hospitalizations in the United States from 2007 to 2017.

Background: End-stage renal disease (ESRD) patients are highly susceptible to peptic ulcer bleeding (PUB). We aimed to assess the influence of ESRD status on PUB hospitalizations in the United States (USA).

Methods: We analyzed the National Inpatient Sample to identify all adult PUB hospitalizations in the USA from 2007 to 2014, which were divided into two subgroups based on the presence or absence of ESRD.

Background And Aim: Early readmissions of spontaneous bacterial peritonitis (SBP) are often associated with poor outcomes. We compared characteristics and outcomes for index and 30-day readmissions of SBP in the USA.

Methods: We analyzed the Nationwide Readmissions Database for 2018 to identify all adult (≥ 18 years) 30-day readmissions of SBP in the USA.

Background: This study aimed to assess the trends and characteristics of celiac disease (CeD) hospitalizations in the United States (US).

Methods: The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of CeD. Demographic trends, associations, and other aspects of CeD hospitalizations were analyzed.

Background: The prevalence of Crohn's disease (CD) and ulcerative colitis (UC) is on the rise worldwide. This rising prevalence is concerning as patients with CD and UC may frequently relapse leading to recurrent hospitalizations and increased healthcare utilization.

Aim: To identify trends and adverse outcomes for 30 d readmissions for CD and UC.

Anti-reflux mucosectomy (ARMS) is an emerging endoscopic treatment for refractory gastroesophageal reflux disease (GERD). We conducted a systematic review and meta-analysis to evaluate the safety and efficacy ARMS in refractory GERD. A comprehensive search of multiple databases (through March 2020) was performed to identify studies that reported outcomes of ARMS for refractory GERD.

Objectives: Gastroparesis is a debilitating and difficult to manage problem that has been reported in 20% to 90% of lung and heart-lung transplant recipients. The primary objective was to evaluate the safety and clinical effectiveness of per-oral endoscopic pyloromyotomy in relieving gastroparesis after lung transplant. Secondary objectives evaluated the effect of per-oral endoscopic pyloromyotomy on gastroesophageal reflux and allograft function.

Achalasia is an esophageal motility disorder characterized by esophageal aperistalsis and impaired relaxation of the lower esophageal sphincter. Treatment is palliative, aimed at decreasing the lower esophageal sphincter pressure. Pneumatic dilation (PD) is a safe and effective treatment for achalasia.

Background And Aims: Nanoscale nuclear architecture mapping (nanoNAM), an optical coherence tomography-derived approach, is capable of detecting with nanoscale sensitivity structural alterations in the chromatin of epithelial cell nuclei at risk for malignant transformation. Because these alterations predate the development of dysplasia, we aimed to use nanoNAM to identify patients with Barrett's esophagus (BE) who might progress to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC).

Methods: This is a nested case-control study of 46 BE patients, of which 21 progressed to HGD/EAC over 3.

Goals: Our aim was to compare the diagnostic yield of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) versus combined fine needle aspiration and fine needle biopsy (EUS-FNA + FNB) in the evaluation of solid pancreatic masses (SPMs).

Background: EUS-FNA and EUS-FNB are established methods to diagnose SPMs. No studies have evaluated the efficacy of combination of both (EUS-FNA + FNB).

Article Synopsis
  • The study investigates how to better identify patients with locally advanced esophageal adenocarcinoma (EAC) who could benefit from neoadjuvant therapy, as some are misclassified as early stage based on clinical staging.
  • A retrospective analysis of 97 patients revealed that certain clinical characteristics, such as dysphagia and tumor size greater than 2 cm, can predict the likelihood of advanced disease.
  • A predictive model was created, indicating that those with specific symptoms and tumor features have a 70% chance of having locally advanced EAC, which can improve treatment decision-making.

Background: Existing literature on post-endoscopic retrograde cholangiopancreatography (ERCP) complications in patients with liver transplant remains scarce and largely inconsistent. We therefore aimed to systematically review and analyze the literature on complication rates associated with ERCP in patients with liver transplant.

Methods: We performed a comprehensive literature search in PubMed, PubMed Central, Embase, and ScienceDirect databases from inception through March 2020 to identify all the studies that evaluated post-ERCP complications in patients with liver transplant.

Goals: The aim was to assess the effectiveness of fecal microbiota transplantation (FMT) against medical therapy (MT).

Background: FMT has shown good outcomes in the treatment of Clostridium difficile infection (CDI). We aimed to conduct a systematic review and meta-analysis to compare the effectiveness of FMT versus MT for CDI.

Pseudomelanosis coli is historically associated with anthraquinone laxatives and is often used as a surrogate marker for chronic laxative use. The opioid epidemic has seen an increase in laxative use for chronic constipation. Anthraquinone laxatives have demonstrated tumorigenic potential in animal studies due to their apoptotic effects on colonic epithelial cells.
