The rise in incidence of esophageal cancer (EC) in the USA over the last four decades has been well documented; however, data on trends in long‐term survival and impact on modern therapies associated with survival are lacking.

Purpose of review To highlight the gastrointestinal helminths in the context of renewed global commitment to control or eliminate neglected tropical diseases in the coming decade. Recent findings Two key documents, namely the 2012 London Declaration for Neglected Tropical Diseases and the 2013 World Health Assembly resolution, emphasize the importance of mass drug administration (MDA) for controlling several key neglected tropical diseases. These documents, together with the Global Burden of Disease Study 2010, establish the major gastrointestinal helminth infections, including the soil-transmitted helminthiases – ascariasis, trichuriasis, hookworm, and strongyloidiasis – in addition to the intestinal and liver fluke infections, as some of the most important gastrointestinal infections of humankind. Current MDA approaches using single-dose albendazole or mebendazole are effective for ascariasis, less so for other soil-transmitted helminth infections. Expanded use of albendazole in combination with ivermectin would ensure improved drug efficacies against trichuriasis and strongyloidiasis. There is no effective elimination strategy for targeting hookworm and liver and intestinal fluke infections through current MDA approaches. Summary The global community must expand current MDA efforts, while simultaneously developing additional drugs, diagnostics, and vaccines alongside better utilizing transmission dynamics and modeling, if it is to successfully meet the goals and targets established by policymakers.

Esophageal variceal bleeding is a severe complication of portal hypertension with significant morbidity and mortality. A substantial portion of cirrhotics fail to respond to conventional medical therapy and band ligation, necessitating alternative treatments including self‐expanding metal stent (SEMS) placement for acute refractory esophageal variceal bleeding. In the present study, we carried out a systematic review and structured meta‐analysis of all eligible studies to evaluate the technical feasibility, safety, clinical efficacy, and survival advantage of SEMS placement for the treatment of of acute esophageal variceal bleeding.

Letter to the Editor: We read with great interest the article by Leithead et al ,1 which showed that non-selective beta-blocker (NSBB) therapy was found to be beneficial for patients with ascites, and associated with reduced waitlist deaths even in those with refractory ascites. The study by Serste et al 2 was the first to suggest that NSBB therapy is associated with an increased mortality in patients with cirrhosis and refractory ascites. This led to the NSBB ‘therapeutic window’ hypothesis that claimed that the window would close once a patient developed refractory ascites.3 However, the issue remains controversial as subsequent publications have shown disparate results. In a recent study by Bossen et al ,4 which compiled data from three randomised …

Gastroparesis has traditionally been a largely medically managed disease with refractory symptoms typically falling under the umbrella of the surgical domain. Surgical options include, but are not limited to, gastrostomy, jejunostomy, pyloromyotomy, or pyloroplasty, and the Food and Drug Administration approved gastric electrical stimulation implantation. Endoscopic management of gastroparesis most commonly involves intrapyloric botulinum toxin injection; however, there exists a variety of endoscopic approaches on the horizon that have the potential to radically shift standard of care. Endoscopic management of gastroparesis seeks to treat delayed gastric emptying with a less invasive approach compared to the surgical approach. This review will serve to highlight such innovative and potentially transformative, endoscopic interventions available to gastroenterologists in the management of gastroparesis.

Recurrence of hepatitis C virus (HCV) following liver transplantation (LT) is universal for those with ongoing viraemia and is associated with higher rates of allograft failure and death. However, the optimal timing of HCV treatment for patients awaiting transplant remains unclear.

Introduction: Esophageal variceal bleeding is a severe complication of portal hypertension with significant morbidity and mortality. Although traditional screening and grading of esophageal varices has been performed by endogastroduodenoscopy (EGD), wireless video capsule endoscopy provides a minimally invasive alternative that may improve screening and surveillance compliance. Aim of the Study: The aim of the study was to perform a systematic review and structured meta-analysis of all eligible studies to evaluate the efficacy of wireless capsule endoscopy for screening and diagnosis of esophageal varices among patients with portal hypertension. Methods: Searches of PubMed, EMBASE, Web of Science, and the Cochrane Library databases were performed through December 2015. Bivariate and hierarchical models were used to compute the pooled sensitivity and specificity, and to plot the summary receiver operating characteristics curve with summary point and corresponding 95% confidence region. Bias of included studies was assessed using the quality assessment of diagnostic accuracy studies-2. Results: Seventeen studies from 2005 to 2015 were included in this meta-analysis (n=1328). The diagnostic accuracy of wireless capsule endoscopy in the diagnosis of esophageal varices was 90% [95% confidence interval (CI), 0.88-0.93]. The diagnostic pooled sensitivity and specificity were 83% (95% CI, 0.76-0.89) and 85% (95% CI, 0.75-0.91), respectively. The diagnostic accuracy of wireless capsule endoscopy for the grading of medium to large varices was 92% (95% CI, 0.90-0.94). The pooled sensitivity and specificity were 72% (95% CI, 0.54-0.85) and 91% (95% CI, 0.86-0.94), respectively, for the grading of medium to large varices. The use of capsule demonstrated only mild adverse events. A sensitivity analysis limited to only high quality studies revealed similar results. Discussion: Wireless esophageal capsule endoscopy is well tolerated and safe in patients with liver cirrhosis and suspicion of portal hypertension. The sensitivity of capsule endoscopy is not currently sufficient to replace EGD as a first exploration in these patients, but given its high accuracy, it may have a role in cases of refusal or contraindication to EGD.

Early transjugular intrahepatic portosystemic shunt (TIPS) used as preventive therapy prior to recurrent bleeding has been recommended in patients presenting with acute esophageal variceal bleeding (EVB) who are at high risk of further bleeding and death. We investigated the impact of early TIPS on outcomes of US patients hospitalized with EVB from 2000 to 2010.

Diverticular hemorrhage is the most common reason for lower gastrointestinal bleeding (LGIB) with substantial cost of hospitalization and a median length of hospital stay of 3 days. Bleeding usually is self-limited in 70–80% of cases but early rebleeding is not an uncommon problem that can be reduced with proper endoscopic therapies. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed by interventional endotherapy including injection, heat cautery, clip placement, and ligation to achieve endoscopic hemostasis. This review will serve to highlight the various interventions available to endoscopists with specific emphasis on superior modalities in the endoscopic management of diverticular bleeding.
