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.

The Guest Editors have assembled key opinion leaders to provide state of the art articles on this important update on ERCP.

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.

Upper gastrointestinal bleeding is the leading emergency leading to hospitalization and urgent endoscopy. The field of gastrointestinal bleeding is rapidly evolving. The epidemiology is changing with more complex older patients on anticoagulant and antithrombotic agents presenting with upper gastrointestinal bleeding. The initial management has rapidly evolved with new transfusion thresholds, the use of risk stratification scores and no more nasogastric tubes. There is new data and recommendations on optimal timing of endoscopy. Medical therapies have also evolved with changes in proton pump inhibitor administration and the use of prokinetics to improve endoscopic visualization. Many modifications in endoscopic therapy have recently been advanced including the use of endoscopic ultrasound guided angiotherapy, topical sprays (i.e. Hemospray) and over-the-scope clips. In order to give optimal care to patients, it is critical that practicing gastroenterologists are aware of the many recent advances in management of patients with upper gastrointestinal bleeding.
