Following the development of gray-scale imaging, real-time scanning, Doppler examination, and high-frequency sonography, endosonography is one of the latest major breakthroughs in the history of diagnostic ultrasound.
Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effective, easy-to-use endosono scopic probes.
The availability of specially designed intracorporeal probes for specific natural cavities that are routinely explored by conventional optical endoscopy or palpation has significantly expanded the diagnostic applications of sonography. Transrectal and transvaginal examinations are now performed routinely in many institutions, and virtually all sonographic equipment manufac turers have in their line of products at least one endorectal and one endovaginal transducer.
Most endosonoscopic probes connect to existing scanners, and for radiology departments, the invest ment for transrectal or transvaginal scanning will usually be limited to the purchase of the specific probe. In this book, clinical applications of endosonography excluding transesophageal echocardio graphy are covered by European and North American experts. Current equipment and techniques of examination are described in detail to help newcomers get started in the field of 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. Technical improvements over the past twenty years have made endos copy the procedure of choice for examination of the hollow organs of the genitourinary and gastrointestinal tracts. The development of electro surgical techniques, laser technology, injection therapy, and a wide variety of other modalities now allow the endoscopist to treat many problems that in the past required open surgery.
The simultaneous development of transcutaneous abdominal sonography has had an equally dramatic impact on the practice of gastrointestinal and geni tourinary surgery. The marriage of these proven technologies, known as endoscopic sonography, provides an exciting new modality that promises to further revolutionize the diagnosis and management of many intraabdominal diseases.
Endoscopic sonography opens new frontiers by overcoming the primary limitations of its parent technologies. Fiberoptic endoscopy is limited by the inability to see beyond the luminal surface, this is particularly important when considering neoplastic disease because depth of wall invasion is a key factor in determining treatment.
The limiting factor in transcutaneous sonography is the distance between the transducer and the target organ. With endoscopic sonography, the transducer is placed in close proximity to the target organ.
This allows the use of high frequency waves greater than 5 MHz , which provide better tissue resolution and eliminates the image distortion caused by overlying structures. The available textbooks on endoscopic ultrasound EUS typically focus on technique and interpretation of commonly observed images and scenarios and are aimed primarily at trainees.
However, independent practitioners of EUS are often challenged by unusual cases which they are expected to handle competently despite the absence of authoritative guidance. The case material is organized principally according to anatomic site. Approximately case reports are included, each of which is accompanied by an average of three to five high-quality EUS images; in addition, CT and PET scans are shown when appropriate.
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 Wild and Reid reported the first results of transrectal ultrasound of the prostate [1]. In Lutz introduced an A-mode ultrasonic probe which could be introduced via the biopsy channel of an endoscope [2]. In and 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]. Endosonography 4th Edition.
