Biomedical Optics in Otorhinolaryngology: Head and Neck Surgery gives an overview of current technology in biomedical optics relevant to the field of Otorhinolaryngology and head and neck surgery. It provides a comprehensive source of knowledge for researchers and active clinicians seeking information on the principles and practical use of novel diagnostic and therapeutic technology. While most books focus exclusively on laser surgery, which has been largely unchanged for the past 15 years, optical diagnostics and head and neck PDT (photodynamic therapy) are usually entirely overlooked. This book contains a basic introduction into the physics of light and its propagation, lasers and low-coherent light sources, and photon-tissue interaction in relation to therapeutic and diagnostic use. The principles of various imaging techniques are also discussed ( i.e. optical coherence tomography in its variations), as well as the principles and practice of lasers for surgical use on the therapeutic side.

This book comprehensively summarizes the current state of knowledge on malignancies of the gastrointestinal tract. Dedicated organ-based chapters evaluate current treatments and management and provide information on incidence, etiology and biological characteristics. The state of the art in the radiologic and endoscopic staging of gastrointestinal malignancies is described, and guidance is offered on the role of interventional radiology and interventional gastroenterology in the treatment of these challenging tumors. In addition, the book explores novel and evolving treatments, including personalized systemic therapy and minimally invasive surgical and radiology techniques, and addresses patient-reported outcomes and survivorship challenges. It closes by discussing animal models of gastrointestinal malignancies and examining the significance of the Ras superfamily of GTPases. It will be of benefit to all surgeons, oncologists and other specialists who treat these malignancies, as well as to trainees looking to increase their understanding of the field.

This book presents a theoretical and practical overview of computational modeling in bioengineering, focusing on a range of applications including electrical stimulation of neural and cardiac tissue, implantable drug delivery, cancer therapy, biomechanics, cardiovascular dynamics, as well as fluid-structure interaction for modelling of organs, tissues, cells and devices. It covers the basic principles of modeling and simulation with ordinary and partial differential equations using MATLAB and COMSOL Multiphysics numerical software. The target audience primarily comprises postgraduate students and researchers, but the book may also be beneficial for practitioners in the medical device industry.

This book is derived from a series of articles written for dental practitioners and first published in Dental Update. The articles were written as a consequence of running a weekly clinic, concerned largely with the correction of referred endodontic problems. In most cases the 'problems' did not exist and were treated simply by redoing the root filling or by undertaking a straightforward apicectomy. Regrettably, in many other cases, the problem would not have existed had the previously undertaken, and potentially simple, apicectomy been carried out competently. There is no good reason why apical surgery should not be undertaken by the general dental practitioner as part of the patient's overall treatment. After all, the problem will usually have arisen either during, or as a result of, routine dental treatment. In addition, the tooth may require to be restored, either at the time of surgery or fairly soon thereafter. Regrettably, inexperience in the handling of soft tissues, and concern about the risk of damage to associated structures, often deters the dentist from attempting what is, if sensibly approached, an uncomplicated minor dento-alveolar operation. Chapters 1-8 introduce the reader to the basic techniques of apicectomy. Chapters 9, 12, 16 and 17 will, it is hoped, help the interested dentist to develop a competence to treat more complex cases, once he or she has become proficient in the basic skills.

This book is part of a series covering surgical specialties. The volumes are multi-authored, containing brief chapters, each of which are devoted to one or two specific questions or decisions within that specialty that are difficult or controversial. The volumes are intended as a current and timely reference source for practicing surgeons, surgeons in training, and educators that describe the recommended ideal approach, rather than customary care, in selected clinical situations.

This book provides a concise, focused and clinically relevant summary of complications and emergencies related to bariatric surgery. The first section of the text addresses general complications related to anesthesia and the stress of surgery, including issues such as deep vein thrombosis, pulmonary embolism, hemorrhage, pneumonia and cardiac complications. Additionally, this section addresses the workup of the bariatric patient with abdominal pain. The second portion of the text focuses on gastric bypass and sleeve-specific complications, including staple line and anastomotic leaks, internal hernia, marginal ulceration, GI obstruction, hernia formation and gallstone disease. The third portion of the book examines metabolic, nutritional and psychological complications after bariatric surgery. The text also covers management of weight loss failure. Bariatric Surgery Complications and Emergencies serves as a very useful resource for physicians and surgeons who are involved in any parts of evaluation or management of bariatric patients suffering from postoperative complications or emergencies including bariatric surgeons who perform these operations on a regular basis, non-bariatric general surgeons who cover such patients when on-call, surgical trainees, and primary care physicians.

Despite the fact that the incidence of gastric cancer is declining in the Western world, it remains a significant problem with respect to accurate diagnosis and treatment since it has a high mortality rate. In June 1989 an International Conference was held at the University of Rome "La Sapienza" entitled "New Trends in Gastric Cancer: Background and videosurgery." During this meeting background information on the aetiopathogenesis of gastric cancer was presented together with talks and video presentations on the latest advances in the treatment of gastric carcinoma, both from the European and Japanese experience. Because of the poor prognosis of gastric carcinoma there is increasing pressure for early detection. Some of the problems in the early detection of gastric carcinoma are discussed together with methods of surveillance of high-risk subjects. It is generally accepted that the surgical approach to gastric carcinoma should take into account the site and extent of the lesion and there are chapters on new methods for pre and intraoperative staging of the disease which allow a more logical approach to surgery. A comparison between Japanese and Western rule and results was attempted and reasons for the differences were investigated. Since the field is still evolving not all aspects could be covered, and those angles not approached in this book will be addressed in a second International Conference to be held in Rome in June 1990.

This book provides a state-of-the-art update, as well as perspectives on future directions of research and clinical applications in the implementation of biomechanical and biophysical experimental, theoretical and computational models which are relevant to military medicine. Such experimental and modeling efforts are helpful, on the one hand, in understanding the aetiology, pathophysiology and dynamics of injury development and on the other hand in guiding the development of better equipment and protective gear or devices that should ultimately reduce the prevalence and incidence of injuries or lessen their hazardous effects. The book is useful for military-oriented biomedical engineers and medical physicists, as well as for military physiologists and other medical specialists who are interested in the science and technology implemented in modern investigations of military related injuries.

This thesis lays the groundwork for the automatic supervision of the laser incision process, which aims to complement surgeons' perception of the state of tissues and enhance their control over laser incisions. The research problem is formulated as the estimation of variables that are representative of the state of tissues during laser cutting. Prior research in this area leveraged numerical computation methods that bear a high computational cost and are not straightforward to use in a surgical setting. This book proposes a novel solution to this problem, using models inspired by the ability of experienced surgeons to perform precise and clean laser cutting. It shows that these new models, which were extracted from experimental data using statistical learning techniques, are straightforward to use in a surgical setup, allowing greater precision in laser-based surgical procedures.
