Together with Consulting Editor Dr. Charles Lightdale, Dr. Qiang Cai has put together a comprehensive issue devoted to gastroparesis. Expert authors have contributed clinical review articles on the following topics: Epidemiology and Pathophysiology of Gastroparesis; Non-Diabetic Gastroparesis; Clinical Manifestations and Natural History of Patients with Gastroparesis; Evaluation of Patients with Suspected Gastroparesis; Symptomatic Management of Gastroparesis; Gastric Electrical Stimulator for treatment of Gastroparesis; Surgical Treatment for Gastroparesis; Botulinum Toxin Injection for Treatment of Gastroparesis; Stent Placement for Treatment for Gastroparesis; Technical Aspects of Per Oral Endoscopic Pyloromyotomy; Gastric Emptying Scintigraphy for Evaluation of Patients with Gastroparesis before Per Oral Endoscopic Myotomy; Outcomes of Per Oral Endoscopic Pyrolomyotomy in France; Outcomes of Per Oral Endoscopic Pyloromyotomy in China; Outcomes of Per Oral Endoscopic Pyloromyotomy in the United States.. Readers will come away with the information they need to improve endoscopic techniques and improve patient outcomes.

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.

Dr. Soetikno has organized a comprehensive issue devoted to the detection and diagnosis of non-polypoid colorectal neoplasms with special emphasis on sessile or flat colon adenoma.? Top experts in the field have supplied the latest clinical information in the following areas: Non-Polypoid Colorectal Neoplasms in Ulcerative Colitis; Detection and Diagnosis of Non-Polypoid Colorectal Neoplasms; Image-Enhanced Endoscopy to Detect and Diagnose Non-Polypoid Colorectal Neoplasms; CT Colonography and Non-Polypoid Colorectal Neoplasms, as well as Endoscopic Mucosal Resection of Non-Polypoid Colorectal Neoplasms.? This issue is an important one as there are not many references on the topics that are as comprehensive.
