Gastroenterologic Endosonography

The introduction of endosonographically guided fine-needle biopsy has led to increasing use of longitudinal scans in the endosonographic diagnosis of tumors and other diseases of the upper gastrointestinal tract as well as of the pancreas. In this handbook, experts concentrate primarily on practical aspects of using endosonography with longitudinal scans. Examination techniques, interpretation of the ultrasound images, and normal anatomy with important guiding structures are demonstrated by means of 3D CT images and the corresponding endosonographic images. In addition, pathological endosonographic findings and the current status of diagnosis using fine-needle biopsy are described.

Endoscopic ultrasound has revolutionized the approach to lesions inside and outside the gastrointestinal tract. It has opened the door for gastroenterologists to explore organs outside of the GI lumen, such as the lymph nodes, lung, pancreas, and liver. Endoscopic Ultrasound covers all aspects of endoscopic ultrasound, from the basics to the interventional indications. Richly detailed chapters describe the utility of EUS in different parts of the body and are organized based on body site Pioneers in the field summarize new studies, and the direction of EUS in practice. Endoscopic Ultrasound provides a ready reference that will help physicians and support staff that are beginning EUS, as well as trained ultrasonographers who wish to arm themselves with a comprehensive reference and explore the future of the field.

A must-have reference for both beginning and experienced endosonographers, Endosonography, 5th Edition, coves the full spectrum of endoscopic ultrasound (EUS) in a single, convenient resource. Concise, easy-to-navigate chapters keep you abreast of changes in this dynamic field, and nearly 150 procedural videos reinforce techniques of common, clinically relevant procedures. Covering both standard and newer techniques, this authoritative reference covers everything you need to know—from basic applications to advanced interventions. Guides you step by step through both introductory and advanced techniques, covering everything from interpretation and accurate diagnosis to treatment recommendations. Employs a user-friendly, templated format to cover all topics from basic applications to advanced interventions, with procedures organized by body system. Includes a new chapter on Endo-Hepatology, and an increased focus on using EUS for interventions. Features 20 new procedural videos covering topics such as esophageal and gastric cancer; mediastinal lesions and lung cancer; pancreatic tumors; and bile duct, gallbladder, and ampullary lesions. Covers recent improvements and new applications in guided fine-needle EUS for diagnosis and cancer staging. Features high-quality images with correlative illustrations, diagnostic algorithms, examination checklists, and key points boxes throughout. Provides nearly 150 how-to-videos of both diagnostic and therapeutic procedures performed by expert endosonographers that demonstrate effective techniques and the proper use of equipment. Provides practical information on establishing an endoscopic practice, from what equipment to buy to effective cytopathology services.

Year on year, there continue to be dramatic changes in endoscopic ultrasonography (EUS) since it was first introduced 30 years ago. Advances in technology have meant that as well as being used in the diagnosis of gastrointestinal disorders, EUS is now one of the primary diagnostic and therapeutic modalities used in GI endoscopy. Back and improved for a new edition, Endoscopic Ultrasonography is the market-leading book covering the topic. Written by leading experts in the field, it provides a technical how-to approach to learning this advanced endoscopic procedure. The highly-acclaimed authors provide step-by-step guidance to the fundamentals of EUS, giving clear instructions on the instruments involved, the correct sedation procedures to follow and how EUS should be performed safely and effectively. Every chapter discusses a specific aspect of EUS as it relates to a particular gastrointestinal disorder or organ system. Brand new to this edition are: 1) Seven new chapters on the hottest topics in EUS: Learning Anatomy for EUS; Elastography; Lung Cancer; Autoimmune Pancreatitis; EUS for Liver Disease; Biliary Access; Pancreatic Fluid Collection Drainage 2) A complete update of all previous chapters to reflect the most current clinical recommendations 3) A host of new color images in every chapter Endoscopic Ultrasonography 3rd edition is the ideal tool to consult to improve EUS skills and improve patient management, and an essential purchase for all gastroenterologists and endoscopists.

Transcutaneous ultrasonography is an established procedure for diagnosis and therapy in gastroenterology. However, ultrasonic images can often be hampered by pulmonary and intestinal gas and by bony and adipose tissue. In 1956 Wild and Reid reported the first results of transrectal ultrasound of the prostate [1]. In 1976 Lutz introduced an A-mode ultrasonic probe which could be introduced via the biopsy channel of an endoscope [2]. In 1978 and 1980 Hisanaga performed echocardiography using an ultrasonic transducer attached to the tip of a flexible instrument [3, 4]. In animal studies and later on in humans Di Magno has used an echoendoscope in which a small transducer was attached at the tip of a fiberoptic endoscope [5, 6]. The purpose was to overcome the limitations of transcutaneous ultrasonography by directly approaching target lesions with a high-frequency ultrasound source via the gastroin testinallumen. SJlbsequently, the first series of endoscopic ultrasonography (EUS) examinations were reported during the European congress in Stockholm [7]. The purpose of this book is: 1. To evaluate the technique and the equipment for endoscopic ultrasonography 2. To evaluate in detail the endosonographic pattern of the normal and abnormal wall structure 3. To analyze a large consecutive series of various gastrointestinal malignancies in order to determine the usefulness and accuracy of EUS in the detection, staging, and therapy of malignant diseases 4. To compare EUS with other imaging techniques References 1.

Since endoscopic ultrasonography was first used approximately 15 years ago, it has become a valuable adjunct tool, supplementing endoscopy, conventional ultrasound, and CT for a large number of specific indications. Features of this book include: physical laws and technology as necessary for an understanding of the imaging technique; indications and clinical value of the method for specific indications; examination technique in normal findings as the basis of evaluation: for example, passage through the esophagus and stomach are shown step by step using more than 30 illustrations. All original photographs are explained with correlated line drawings, aiding the unexperienced examiner to interpret images with confidence. Written by authors who were pioneers in the method, and who have established an international reputation.

This volume provides a comprehensive, state-of-the-art overview on interventional endoscopic ultrasound (EUS). Each chapter covers a single procedure or related group of procedures, features a detailed literature evaluation and tips on these cutting edge endoscopic techniques, and is accompanied by a comprehensive endoscopic video and illustrative endoscopic and ultrasonographic images. The text also reviews adverse events related to interventional EUS, both how to avoid them and how to manage them when they arise. Written by to endoscopic experts in the field, Interventional Endoscopic Ultrasound is a valuable resource for practicing gastroenterologists who perform advanced endoscopy.
