Colonoscopy is the bread and butter for endoscopists and advances in the procedure to reduce time, improve efficiency, and prevent errors are very important for this group. The newest advances look at colonoscopy efficiency and a better way to target tissue sampling, which avoids random biopsies and instead looks at ways to predict areas for sampling. The Guest Editors have selected top experts to provide these important updates and they also address current thinking that questions the continued value of colonoscopies as predictors of colon cancer. The issue will be a very popular one, and it needs to be heavily promoted.

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 book provides an overview on the critical role of diagnostic imaging in the assessment of patients with suspected alimentary tract perforation, an emergent condition that requires prompt surgery.

Particular attention is paid to MDCT, with full description of its role in a range of scenarios at various levels of the alimentary tract. Imaging of GI tract perforation in different patient groups, such as pediatric patients, the elderly and oncologic patients, is also addressed. This volume will greatly assist residents in radiology, radiologists and physicians who are daily involved in the management of patients with clinically suspected alimentary tract perforation.

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).

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.

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.

Dr Roy Soetikno and Dr Tonya Kaltenbach are the editors for this issue of Gastrointestinal Endoscopy Clinics of North America, which is devoted to the improved detection and management of early neoplasia in inflammatory bowel disease. An important aspect of Dr Soetikno's outstanding career has been the bridging of endoscopic methods between Japan and the United States. Endoscopists in Japan have a better record of detecting subtle flat GI lesions. From the earliest days of endoscopy, it is fair to say that Japanese endoscopists have emphasized visual identification, analysis, and photo documentation of small GI lesions. The colon has been no exception. Dr Soetikno has incorporated these techniques, which have become increasingly feasible with steady improvement in modern digital endoscopes. Identifying small flat premalignant lesions and early cancers in patients with colitis can be lifesaving. Dr Soetikno and Dr Kaltenbach have edited an extraordinary issue of the Gastrointestinal Endoscopy Clinics of North America devoted to teaching and promulgating these methods, including an extensive photo atlas, which should be an invaluable resource for all academic specialists and practicing gastroenterologists.
