This book is a completely up-to-date review of the basic tests available in gastroenterology. It is based on a detailed critical analysis of recently described procedures and the review of more traditional methods; each is as signed its correct place in the modern management of patients. Emphasis is placed on those techniques with which the authors have practical experience. The most useful investigations are indicated in the table of contents by heavy type. Comprehensive references are included to provide information about the selection, performance and interpretation of tests. The book is designed for trainees and clinicians without special expertise in gastroenterology, as well as being a shelf manual for the gastroenterologist and the staff of gastrointestinal investigation units. Special thanks are due to the nursing staff of the Day Ward, Bishop Auck land General Hospital; Mr P. Grencis, Medical Photographer; Dr S. Desai, Radiologist; and Amanda Gallagher who typed the manuscript. Malcolm C. Bateson Ian A. D. Bouchier 1988 xu CHAPTER 1 Intubation The passage of various forms of nasogastric, duodenal and intestinal tubes is basic to many of the diagnostic procedures performed in the gastrointestinal system. Method Whenever possible the patient's fullest co-operation should be obtained. If the patient is taking any drugs which might influence the test to be under taken these should be discontinued."

These exercises are meant for students and practitioners who wish to familiarize themselves with the normal and pathologieal computerized tomographie radioanatomy of the abdomen. The iconography is suffieiently characteristic to be read without the help of clinical or biological data. It comprises both normal and pathologie findings. Analysis of scans is comprised of two steps. The first part consists of the detailed study of normal scans, whieh serve as a reference. For this, eight main slice levels have been considered necessary and sufficient: neces sary since a certain number of slices are indispensable for the exploration of the abdomen; sufficient because a larger number of slices would risk rendering memorization difficult. The second part involves a study of the pathologie findings, organ by organ. Acknowledgements. Appreciation is extended to all those who have helped in realizing this study and, more particularly, to our friends and colleagues, J. L. DIETEMANN, C. Roy, J. L. BURGUET, M. VOUGE, and J. W. SOUITER. We would also like to thank Dr. J. WIECZOREK for his friendly assistance and advice in the planning and presentation of figures and schemata. 1 Technical Note Computerized tomography of the abdomen begins with an initial image called "scout view". This numbered radio graph of the abdomen is an analogous representation of the information and allows the location of the eight selected slice levels; these are represented by horizontallines. The slices are 10 mm thick and are taken at intervals of 2.5 cm.

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.

Fibrin plays a central role in wound healing. It has a hemostatic effect by forming a temporary wound closure and assists in neovascularization and fibroblast prolifera- tion. It therefore makes the repair of injured or severed parts of the human body by simple glueing possible, a notion that men have dreamed of since ancient times. The first modern attempts in this direction, using clotting substances derived from human blood to achieve hemostasis, were reported by Bergel (in 1909), Grey (in 1915), and Harvey (in 1916), who used fibrin powder or fibrin patches to control bleeding from parenchymatous organs. Two decades later Young and Medawar (1940) and Cronkite (1944) used blood plasma or fibrin solutions, adding thrombin to seal nerve anastomoses and to fix skin grafts in humans. Due to the poor adhesive strength of the fibrinogen the results were unsatisfactory. In 1972 a new era in fibrin sealing was initiated by Matras. By using highly concentrated fibrinogen in combination with factor XIII (fibrin-stabilizing factor) and by delaying fibrinolysis with a fibrinolysis inhibitor (aprotinin), a method was developed which after satisfactory results in animals, soon began to be applied in humans.

In OCtober 1986, recognized authorities from a variety of disciplines met in Lisbon, Portugal, to review recent knowledge on eicosanoids - i. e., prostaglandins, throm boxane A , and leukotrienes - and their role in gastrointestinal diseases. 2 Briefly, in the stomach endogenous as well as exogenous prostaglandins may mediate cytoprotective actions in that they stimulate gastric mucus production, bicar bonate secretion and cellular regeneration while providing adequate mucosal blood flow. In contrast, thromboxane A2 by vasoconstriction may act as an ulcerogenic substance. Diarrheal states may be associated with prostaglandins of types E and F as they are capable to enhance intestinal water and electrolyte secretions. In chronic in flammatory bowel disease, mucosal synthesis of leukotrienes was found to be increased more markedly than that of prostaglandins suggesting that leukotrienes may have a major part in the pathogenesis of that disease. In this volume, which is an elaborated collection of the papers given on occasion of the above-mentioned symposium, the facts and problems associated with prostanoid substances are dealt with in four sections on 1. biochemistry, biology and pharmacology of eicosanoids, 2. physiologic and pathophysiologic aspects, 3. established therapeutic implications, and 4. treatment perspectives. We believe that the publication of these contributions by leading workers in the given fields provides a comprehensive and up-to-date appraisal of the role of eicosanoids in gastrointestinal diseases, and it is hoped that this volume will be of value to both basic scientists and practicing clinicians.

Die Endoskopie vermochte bisher Gewebsformationen zu dehnen, zu durchtrennen, abzutragen und zu zerstoren. Gewebedefekte auszufullen, miteinander zu vereinigen und zu heilen, war bislang endoskopisch nicht moglich. Die Einfuhrung von Fibrinklebern eroffnete neue Anwendungsbereiche. Der Kleber kann, in seine Komponenten getrennt, uber doppellumige Sonden uber beliebig weite Strecken an den vorgesehenen Einsatzort unter Sicht des Endoskopes transportiert werden. Die Klebung von Fisteln, Rupturen oder Leckagen an Bronchusstumpfen, im Lungenparenchym oder an gastrointestinalen Anastomosen kann heute komplizierte Heilungsverlaufe und riskante operative Re-Interventionen ersetzen. Die spezielle Technik der endoskopischen Fistelklebung wird in diesem Buch erstmals zusammenfassend und interdisziplinar erortert. Daneben werden neue Moglichkeiten zur Stillung gastrointestinaler Blutungen mit Fibrin durch intramurale Injektion oder oberflachlichem Spray besprochen. Grundlegende Untersuchungen zeigen, dass im Vergleich zu anderen Substanzen, die Fibrinapplikation in das Gewebe zu deutlich geringerer Traumatisation und zu geringeren entzundlichen Reaktionen bei gleichem Hamostaseeffekt fuhrt. Ziel des vorliegenden Buches ist, verstreute Einzelbeobachtung zu sammeln, zu ordnen und zu vergleichen, um dem interessierten Leser die neue Technologie der Verklebung von Defekten und der Hamostase mit biologischen Substanzen zu vermitteln.

Das Spektrum der in den westlichen Industrienationen filhren- den Krankheiten und der darauf basierenden Thdesursachen hat sich in den letzten J ahrzehnten gewandelt. Wahrend frliher die Infektionskrankheiten und speziell die Thberkulose den hochsten Todeszoll forderten, sind in den Jahrzehnten nach dem zweiten Weltkrieg mit steigendem Wohlstand die Herz- und GefaBkrankheiten an die erste Stelle gerlickt. Trotz gewis- ser Erfolge in der Pravention in einigen Uindern wie z. B. in den USA, Kanada, Australien; aber auch in einigen Gebieten West- europas, in denen die Zahl der tOdlichen Hirnschlage und Herzinfarkte inzwischen wieder rlicklaufig ist, wird die Spit- zenposition in der Todesursachenstatistik hier auch weiterhin von diesen Krankheiten eingenommen. In anderen Uindern wie z. B. in Osteuropanehmen die Erkrankungsraten weiter zu. Wenn man sich fragt, was getan werden kann, urn weitere Er- fqlge auf diesem Gebiet zu erzielen, dann ist ein Blick in die Lander des Fernen Ostens hilfreich. In der Volksrepublik Chi- na undin J apanliegt die Sterblichkeit an koronarer Herzkrank- heit bzw. an Herzinfarkten flinf- bis zehnmal niedriger als in der Bundesrepublik Deutschland. Arteriosklerotische Durch- blutungsstorungen der unteren Extremitaten, auch diabeti- sche GefaBerkrankungen kommen dort kaum vor. Vergleicht man die Lebensweise der Bevolkerung in diesen Uindern mit den Verhaltnissen in den westlichen Industriena- tionen, so fallenerhebliche Unterschiedeinder Ernahrungauf. Wahrend in China Fleisch und Molkereiprodukte in deutlich geringeren Mengen als bei uns verzehrt werden, besteht der Hauptanteil der Ernahrung aus einer an pflanzlichem EiweiB und Schlackenstoffen reichen Kost.

Management of Swallowing and Feeding Disorders in Schools examines the most significant issues in swallowing and feeding facing school-based speech-language pathologists (SLPs). Topics addressed are unique to the school setting, ranging from organizing a team procedure in a district to serving children with complex medical issues, behavioral feeding disorders, and neurological feeding disorders. Ethical, legal, and cultural issues are also addressed.Many students exhibit the signs and symptoms of dysphagia, and children who were originally treated for dysphagia in hospitals and other settings often begin attending public schools at three years old. The difficulty they had with swallowing and feeding frequently follows them to the school setting. Further, there are many students who develop swallowing and feeding disorders as a result of traumatic brain injury, neurological disorders and syndromes, behavioral disorders, and so forth. The range of students needing services for swallowing and feeding disorders in the school setting can be from three to twenty-two years of age and from mild dysphagia to tube feeding.The identification and treatment of swallowing and feeding disorders in schools is relatively new. There are still many districts in the country and internationally that do not address the needs of children with dysphagia. As school-based SLPs take on the challenge of this population there is a need for information that is current, accurate, and thorough. University programs include very little training, if any, at this time in the area of swallowing and feeding in the school setting. This text is appropriate for both a dysphagia course as well as courses that train SLP students to work with school-aged students.

N. Rietbrock Wachsendes Qualitatsbewusstsein beschrankt sich nicht nur auf die Guter des taglichen Bedarfs, sondern gilt auch fur die im Krankheitsfall zu verordnenden Arzneimittel. Die Qualitat ist vom pharmazeutischen Hersteller im Zulassungsverfahren nachzuwei- sen. So schreibt der im zweiten Gesetz zur Anderung des Arzneimittelgesetzes vom 16. August 1986 neu eingefugte 11a bindend vor, dass in der Fachinformation "die pharma- kologischen und toxikologischen Eigenschaften und Angaben uber die Pharmakokinetik und Bioverfugbarkeit, soweit diese Angaben fur die therapeutische Anwendung erfor- derlich sind ..." enthalten sein mussen. Damit schrankt der Gesetzgeber aber auch bewusst die Angaben zur Pharmakokinetik und Bioverfugbarkeit auf therapeutisch relevante Arzneigruppen ein. Folglich bleibt die Erbringung der Daten praktikabel. Es liegt nicht im Sinne des Gesetzgebers noch in dem des Herstellers in Anbetracht der limitierten Zahl der medizinischen Institute mit ent- sprechender Ausrichtung, des relativ grossen Zeitaufwandes und der nicht unerheblichen Kosten fur alle Arzneimittel eine generelle Regelung zu treffen. Pharmakokinetik und Bioverfugbarkeit sind fur die therapeutische Anwendung erforder- lich unter anderem bei Arzneimitteln, die bei Uberdosierungen zu gravierenden unerwunschten Wirkun- gen fuhren konnen; bei Arzneimitteln, die vorwiegend renal eliminiert werden und bei denen die Gefahr einer verstarkten Kumulation bei eingeschrankter Nierenfunktion besteht; bei Arzneimitteln mit einem "first pass" Effekt; bei allen Arzneimitteln mit geringer therapeutischer Breite. Damit wird aber auch der Zweck solcher Studien klar: Qualitat ist ein relatives Merkmal eines Arzneimittels. Die Validitat dieses Merkmals ist immer im Zusammenhang mit dem klinischen Krankheitsbild zu sehen.

This book, the seventh in the series Exercises in Radiological Diagnosis, deals with sonography, an imaging procedure in which the ability of the radiologist plays an exceptionally important role. The author, Catherine Roy, has very extensive experience in the clinical use of sonography. She has selected the images, which are of excellent quality, with great care to illustrate a wide range of conditions and has supplemented them by commentaries and discussions which are easy to comprehend. The systematic use of schematic drawings to interpret the images makes it possible for the reader to follow the author's approach without any difficulty. Schematic drawings are par ticularly important in sonography because the relationship be tween the details in the images and the anatomy may be very weak. Images, schematic drawings, and text (both commentaries and interpretations) are three didactic elements which Cathe rine Roy has skill-fully combined in these exercises into an excellent whole. A.

It has brought about changes in the procedure of additional investigations and even rendered part of conventional radiology redun dant, particularly that concerning the bile ducts. These exercises are meant for students or physicians who already have basic knowledge of ultrasound diagnosis. It has not been possible to cover the entire spectrum of abdominal pathology, especially trauma, with 114 cases.

This book is an extraordinary achievement by Jonathan Halevy. To condense the material of three major gastrointestinal textbooks would be triumph enough, but to add a distillate of the contents of ten journals, from 1980 to 1985, requires Herculean vigor. To reorganize all the material under headings which extract concise "facts" from wheat and chaff requires a passionate interest in pa tients together with an understanding of physiology. Fortunately, Jonathan Halevy has just the right combination of clinical and lab oratory interest for him to select the details of what is important. Such compulsive dedication has now made it possible for the prac ticing phYSician, gastroenterologist, or house officer, interested in preparing for board examinations or simply browsing in the field, to have at his fingertips a series of definitions and to put in his pocket the key facts for diagnosis and therapy. Of course, facts by themselves are something of which to be a little wary. Scientists first, doctors regard facts the way farmers look at sheep-to be sheared for their utility. Medicine too often is only a fact-gathering occupation (some lectures send me to wool gathering), in which having the facts sometimes clouds clinical judgment about what is important for the individual patient. - vii viii FOREWORD tionalism and romanticism lie at the two poles of medical practice, but rationalism rules in the 1980s."

Cell surface receptors are multifunctional proteins with binding sites towards the external environment and effector sites which mediate intracellular events. The purpose of this symposium was to bring together investigators who have a com mon interest in those receptors which are located in the liver, and who have studied endocytic mechanisms for various macromolecules like insulin, lipoproteins, epi dermal growth factor and others. Experiments in this particular field of research date back to the early 60-ies but have only recently led to new and important in sight in the molecular basis of receptor mediated uptake in the liver. The structural features which control these mechanisms are currently under intense investigation in many laboratories. Though this symposium largely emphasizes lipoprotein up take and catabolism by the liver, it was the particular intention of the organizers to discuss methodology and results with investigators who are also interested in he patic uptake of macromolecules. This might then eventually lead to new and com mon concepts for both receptor-ligand interaction and internalization processes in the liver. Biochemists, pathologists and gastroenterologists met for two and a half days and discussed their latest data in this so rapidly developing field of basic rese arch. This conference is part of a series on current topics in gastroenterology and hepatology arranged regularly by the Departments of Medicine and Surgery at the University Hospital Eppendorf. If is our hope, that such exchange of information between the different disciplines in medicine will continue. i. k."

In spite of years of tuition and examination, newly qualified doctors are often left inadequately prepared for real-world clinical practice. The major concern is that 'book knowledge' gleaned at medical school does not always translate to safe and effective practical knowhow.Based on the author's many years of expertise as an educator globally, this book helps final-year students make the difficult transition to first-year doctors. Drawing on the latest evidence-based information, it focuses on aspects important to clinical practice in the areas of gastroenterology, cardiology and respiratory medicine such as differentials, investigations and management with full references provided throughout. Also detailed are examination skills; although not the routine form of how to examine but what to be thinking when asked to examine: what conditions should be prevalent in a doctor's mind? And how can these conclusions be reached before even seeing the patient? Practical knowledge like this defines an effective clinician.Clear, concise and rigorous in its approach, this comprehensive volume is indispensable companions to any new doctor in the above fields.

In this age of specialization most patients with diseases of the hind gut and anus are still managed by general physicians or surgeons. The speciality of coloproctology has grown from the art of 'anology', a study of conditions limited to that distance from the anal verge that could be inspected easily by torch- or candlelight or with the aid of a simple speculum. Two centuries ago many proctological ills were often treated by itinerant quacks, partly because the physician considered himself rather too grand to meddle around the anus and the medical profession in general tended to look down on those who studied anal disease. Today, in certain countries, coloproctology has become a speciality every bit as exclusive as urology or orthopaedic surgery, with its own training programme and examinations, usually undertaken after the end of general surgical training. Such super-specialization has undeniable advantages with rapidly advancing technology and therapeutic possibilities. There is no doubt that for the patient suffering from a low rectal carcinoma or severe inflammatory bowel disease there are advantages in being treated by surgeons who are dealing with several cases in a year rather than by a general surgeon who sees such problems relatively rarely. Such specialized colorectal surgery units makes good sense medically and economically in large centres of population with good communications.

The Anglo-Swiss Colo-Proctology Meeting, held at Lausanne in May 1983, enabled numerous specialists to share their experiences of lower gastrointestinal tract pathology. The focus was on ischae mic disease and tumours of the colon, rectum and anus. By featuring ischaemic disease in our programme we hoped to give this too often underestimated process a fair hearing. Ischaemic lesions are far more common than is recognised on clinical grounds alone, particularly in the gastrointestinal tract. Large intestine is chaemia is often confused with other syndromes, especially since the clinical features evoked are, in most cases, atypical. Thus diag nosis is frequently late, with dramatic consequences. The oncology section basically discusses the early diagnosis of gastrointestinal tumours, a prerequisite for improving survival in af fected patients, and also presentation and treatment of certain rare tumours. The third section of this volume covers various diverse subjects including surgical technique, functional disorders of the large intes tine, inflammatory bowel disease, haemorrhoids and investigatory procedures. Several of the articles come from international authorities in their field. Some communications contain unpublished results, and others may lead to new diagnostic and therapeutic methods. We feel that the quality and variety of the texts from the Anglo-Swiss Colo Proctology Meeting merit wide appreciation. We are grateful to Springer-Verlag for accepting these proceed ings for publication."

"Gastrointestinal Disease" is the first monograph in a new series on management and treatment in major clinical subspecialties and patient groups. Further volumes will be published over the next few years. Each book is complete in its own right. The whole series, however, has been prepared to fill a gap, perceived by the publisher, myself and the volume authors, between standard textbooks of medicine and therapeutics and research reviews, symposia and original articles in specialist fields. Each volume aims to provide a concise, up to date account of treatment in its subject area with particular reference to drug therapy. Traditional clinical and therapeutic approaches have been presented in the context of developments in clinical pharmacology. Wherever possible, authorship has been under taken by practising clinicians who themselves have training and experience in clinical pharmacology. The volumes are intended to be guides to treatment, to assist in the choice of drug and other treatment and to provide easy references to drug interactions and adverse reactions. It is expected that these monographs will be particularly useful for the young hospital doctor in training for higher qualifications. However, they should also be valuable to or senior medical students and to those in established hospital general practice who are seeking to update their knowledge and to view recent developments in other fields in a balanced context. The aims of the series should be upheld by this volume on "Gastrointestinal Disease.""

This book of diagnostic exercises cannot be used to good advantage without a good grasp of elementary sonoanatomy and the most common pathologic l images . We have tried to follow a pedagogical progression from the simple to the complicated for each group of clinical situations. We recommend that the sonograms at the beginning of each case study be thoroughly analysed before proceeding to the commentaries which explain the grounds for the final diagnosis. These explanatory remarks are accompanied by the same sonograms, but with arrows and letters added so as to pinpoint the details referred to as the diagnosis progresses. In reading the commentaries it will therefore be a good idea to cover over the figures in which the details are picked out for you, uncovering them one by one as required. 1 Which the reader may obtain from our previous books: Ed., 1982) Ultrasonography of Digestive Diseases (Mosby Publ., 2nd Renal Sonography (Springer Verlag, 1981) 1 Chapter 1 In Which the Reader is Invited to Clean His Glasses 1.1.

Ever since the invention of the fiberoptic endoscope in 1888, gastrointestinal endoscopy has grown increasingly popular in day-to-day patient management. Most recently, a variety of therapeutic procedures are also being performed through the endoscope. With increasing technological advances, new endo scopic procedures will be appearing on the horizon. It, therefore, becomes extremely relevant for the gastrointestinal nurse or assistant to be familiar with various endoscopic procedures. Gastrointestinal Endoscopy and Related Procedures will be a useful and practical guide in the making of a qualified gastrointestinal assistant. This book is notable for its elegant style, illustrations, detailed account of procedures, and especially the instructions on patient care. Discussions on physical preparation of gastrointestinal procedures, helpful hints and instrument care add to the value of this book. The psychological impact on the patient undergoing endo scopic procedures and the nurse's role in alleviating 'the fear of the unknown' also is properly covered in the text. It is refreshing to see a nursing perspective in the writing of this text. Throughout the whole book, one can feel a warm and humane approach towards patients with gastrointestinal disease. All these and more are, of course, a result of Sister Morag Ravenscroft's vast experience along with the guidance of Dr Charles Swan. It is a textbook worth reading and relishing.

Howard C. Thomas In normal subjects the regulatory apparatus of the immune system permits responses to foreign antigens but suppresses those directed to "self' components. Autoimmune disease occurs as a failure ofthis system either as a result of a primary defect in the regulatory apparatus (primary autoimmunization) or because of a change in the antigenicity of the tissues (secondary autoimmunization). Autoaggressive reactions are characterised by the presence of autoantibodies. When these are directed to membrane displayed antigens (Fig. 1) they are probably of importance in the lysis of hepatocytes. Those directed to cytoplasmic antigens may be useful diagnostically but are of unknown pathogenic significance. When no extrinsic aetiological factor can be identified, the process is assumed to be the result of a failure ofthe regulatory system, allowing the spontaneous expansion of a clone of autoreactive lymphocytes. The defect may be generalised or specific to certain groups of self-antigens and thus the autoimmune disease may be either multi- or unisystemic. The recent development of techniques to enumerate and measure the functional activity of the suppressor lymphocytes which control the effector limbs of the immune system has enabled investigators to test whether the various purported autoimmune diseases do have as their basis a generalised defect in immunoregu lation. Assessment of antigen-specific immunoregulatory function is, however, not yet readily available. liver Membrane I Antigen (LIM) I Liver I HLA, A, B, C, Sensitisation to Specific -;::!IIIL. .

The acute abdomen often perplexes the expert as well as the young physician. There are few areas in medicine in which Hippocrates' aphorism-the art is long, life is short, decision difficult, and delay perilous-is more applicable than here. Too often the harried physician fails to listen to the patient who is trying desperately to suggest the diagnosis. The significance of various types and location of pain often are neglected by the doctor. Physical findings are influenced by experience; the presence or absence of tenderness or a mass may be answered in entirely different ways by various observers. Because solid facts frequently are lacking, attempts to resolve diagnostic dilemmas by computer analysis or by algorithms are not likely to be successful. Fortunately, in the great majority of cases, unusual and difficult diagnostic procedures are not necessary for the identification of the acute abdomen and of the major disease. Astute clinical judgment must be based primarily upon careful attention to the pa tient's words and detailed observation."

This book provides a practical overview of the treatment and management of celiac disease. It examines new data which can be merged with clinical aspects to provide a global perspective for the busy clinician. The disease represents 1% of the population and often goes unnoticed for a long time; however, this book aims to reduce the instance of misdiagnoses of symptoms by providing clear guidance in a single book, with contributions from esteemed experts in the field. Advances in Celiac Disease - Improving Paediatric and Adult Care addresses the clinical characterisation of the disease, in both paediatric and adult populations. The clinical symptoms are clearly defined as well as treatment options and follow-up. This book will be an essential resource for clinicians seeking a clear, concise resource to identifying, treating, and managing celiac disease in both adults and children.
