Over a short few decades, the field of pediatric endoscopy has matured from the exploratory to the routine. Performance of endoscopic procedures in children is now a fundamental aspect of the practice of more than 2000 pediatric gastroenterologists in North America, and endoscopic instruments are increasingly being developed with an eye to their pediatric applications. Ensuring safe and effective endoscopy in children requires specific medical knowledge and technical competency, in addition to appropriately designed equipment and settings. Obtaining consent from parents, as well as assent from patients, for the purposes of performing diagnostic and therapeutic gastrointestinal procedures begins with a deep understanding of risks and benefits that endoscopy affords and is typically gained through formal training in the field. Diagnostic endoscopy may help to confirm common pediatric conditions including eosinophilic esophagitis and inflammatory bowel disease, while therapeutic procedures to treat strictures in the GI tract may help children avoid more invasive surgeries. Using endoscopy in children to achieve hemostasis or to remove commonly swallowed foreign bodies, such as lithium batteries or high-powered magnets, can be lifesaving, and the insertion of feeding tubes can help medically complex patients to thrive. In short, pediatric endoscopy is an integral component of healthcare for children, and gaining and understanding of its best practices may help all clinicians to better recognize its role in pediatric disease outcomes.

Helicobacter pylori (H. pylori) infection is a worldwide disease with a significant morbidity and mortality; it is the leading cause of non-ulcer dyspepsia, peptic ulcers and gastric tumors, including low-grade mucosa-associated lymphoid tissue-lymphoma and adenocarcinoma. In addition, it has also been recognized that the interaction between H. pylori and non-steroidal, anti-inflammatory drugs is damaging to the gastroduodenal mucosa. H. pylori treatment still remains a challenge for physicians, since no current first-line therapy is able to cure the infection in all treated patients. This issue will serve to update gastroenterologists on current therapies, evaluation and management of disease progression, and the future of management of H. pylori infection.

This issue of Gastroenterology Clinics of North America is all about acute upper GI bleeding and is divided into two distinct sections: section I is devoted to nonvariceal upper GI bleeding and section II is devoted to variceal upper GI bleeding. Acute nonvariceal upper GI bleeding may originate from the esophagus, stomach, or duodenum, essentially anywhere proximal to the Ligament of Treitz. In Section I, Dr Gianluca Rotondano, Hospital Maresca, Torre del Greco, Italy, begins with a review of the epidemiology and diagnosis of acute nonvariceal upper GI bleeding. We then turn to patient presentation, risk stratification, and how to initially medically manage these bleeding patients. I am pleased to have one of our emergency medicine colleagues, Dr Andrew Meltzer, Department of Emergency Medicine, George Washington University, contribute this important article and provide a unique viewpoint from the emergency department where most of these patients initially present. As we all know, endoscopic hemostasis is the accepted standard of care for patients with acute nonvariceal upper GI bleeding. Moreover, peptic ulcer bleeding is the most common nonvariceal cause of acute upper GI bleeding; thus, Drs Yidan Lu, Yen-I Chen, and Alan Barkun from McGill University, Montreal, Canada, provide an in-depth review of the endoscopic management of peptic ulcer bleeding. Drs Eric Tjwa, I. Lisanne Holster, and Ernst Kuipers from the Erasmus Medical Center University Hospital, Rotterdam, The Netherlands, review the endoscopic management of all other causes of acute nonvariceal upper GI bleeding, and in addition, Drs Louis Wong Kee Song and Michael Levy from the Mayo Clinic, Rochester, Minnesota discuss emerging endoscopic hemostasis treatments, such as topical sprays and over-the-scope clipping devices. Although endoscopic hemostasis is very highly effective, there are unfortunately cases where bleeding is unable to be controlled or when significant rebleeding occurs that is not amenable to endoscopic therapy. Therefore, I have included two articles that provide insight into the question.what if endoscopic hemostasis fails? The first article, written by Drs Philip Wai Yan Chiu and James Yun Wong Lau, from Prince of Wales Hospital, The Chinese University of Hong Kong, focuses on tried and true surgical treatment options. The second article, by Dr Sujal Nanavati, University of California at San Francisco, Department of Radiology and Biomedical Imaging, addresses the alternative treatment strategy of angiographic embolization, which has now emerged as the often preferred salvage treatment strategy. One of the most feared complications of cirrhosis and portal hypertension is variceal hemorrhage. In Section II of this issue, the focus is on variceal causes of acute upper GI bleeding. Usually due to esophageal variceal rupture, this complication occurs in an entirely different epidemiologic and clinical setting than nonvariceal upper GI bleeding. Thus, this topic requires an understanding of many critical issues, including diagnosis and management. We begin Section II with a review of the epidemiology, diagnosis, and early patient management strategies in bleeding esophagogastric varices by Drs Sumit Kumar, Sumeet Asrani, and Patrick Kamath from Mayo Clinic, Rochester, Minnesota. Drs Jawad Ilyas and Fasiha Kanwal from the Baylor College of Medicine, Houston, Texas go on to present the latest evidence on primary prophylaxis of variceal bleeding, both medical and endoscopic. However, for those patients who present with acute esophagogastric variceal bleeding, endoscopic management is the cornerstone of patient management. Drs Andres Cardenas, Anna Baiges, Virginia Hernandez-Gea, and Juan Carlos Garcia-Pagan from the GI/Endoscopy Unit and Barcelona Hepatic Hemodynamic Laboratory, Liver Unit, Barcelona, Spain, provide an evidence-based review of endoscopic hemostasis techniques in acute esophageal variceal bleeding, and Drs Frank Weilert and Kenneth Binmoeller from Waikato Hospital, Hamilton, New Zealand and the California Pacific Medical Center, San Francisco, respectively, discuss the recommended endoscopic management of bleeding gastric varices, including emerging techniques such as EUS-guided intravascular therapies. Next, Drs Sanjaya Satapathy and Arun Sanyal contribute a comprehensive review of nonendoscopic management strategies for esophagogastric variceal bleeding, and last but not least, Drs Kamran Qureshi and Abdullah Al-Osaimi, from Temple University, Philadelphia, Pennsylvania, discuss how to manage the patient with portal hypertensive gastropathy and gastric antral vascular ectasia (also known as watermelon stomach).

By the time this issue of Gastroenterology Clinics of North America is released, it will have been 16 years since infliximab was approved by the US Food and Drug Administration for the treatment of moderate to severe Crohn disease. Not only have we come a long way in understanding the efficacy and safety of infliximab, we are beginning to understand how and when to use the drug. Furthermore, as of this writing, we have five other biologic agents approved for either Crohn disease or ulcerative colitis, and there are many more molecules currently in drug development for these indications. In this issue,the Editors have assembled a collection of experts to provide the most cutting-edge information on the status of biologic therapy for inflammatory bowel disease.

This issue would review a broad range of endoscopic complications throughout the entire GI tract and include complications related to almost all types of endoscopic procedures. Typically, articles and endoscopy courses only briefly mention specific types of complications related to one or two endoscopic procedures. To date, this would be the only issue whose sole focus is on endoscopic complications and their management and will prove a useful resource for the gastroenterologist. The authors will be expert endoscopists from around the country whose knowledge of this topic should be far ranging and include use of new devices.

This issue will be an informative treatise on gastroparesis, a symptomatic chronic disorder of the stomach characterized by delayed gastric emptying in the absence of mechanical obstruction. Gastroparesis is an increasingly recognized and diagnosed disorder. Treatment can be challenging due to several mechanisms which play a role in causing the symptoms. Symptoms of gastroparesis are variable and include early satiety, nausea, vomiting, bloating, and upper abdominal discomfort. These symptoms can range from mild to severe leading to such complications as malnutrition, functional disability, and multiple hospitalizations. The three most common etiologies are diabetes, post-surgical, and idiopathic (unknown). Treatment consists of dietary manipulation, medical, and surgical therapy. The articles will provide a comprehensive review and in-depth information on gastroparesis. Each chapter will be written by an expert in the area. This issue will give the reader a better appreciation for the breadth of gastroparesis.

This issue devoted to Esophageal Function Testing highlights these tests that are complimentary to endoscopy and should be considered after endoscopy is performed. In fact, a prerequisite for performing many of these studies is a negative endoscopy and thus, the endoscopist should be well-informed regarding the indication and utility of these tests. Additionally, some of these newer technologies require endoscopy to be performed during the study as the placement or positioning of the measurement tool will require endoscopic landmarks or direct placement. There have been major advances in most of these older techniques, and new novel measurement paradigms have been created that allow for a more visual and accurate depiction of physiologic and anatomic data. These technologies have evolved to be more akin to an imaging technique and thus, the visual display and data acquisition is much more intuitive and easier to teach to trainees. This review would be of the utmost importance to readers of GI Endoscospy Clinics.
