Colonic diverticula occur when mucosal and submucosal layers protrude through weak points in the muscle wall. Most patients with diverticular disease are asymptomatic, but some may experience abdominal pain without inflammation. Diverticular disease may develop as diverticulitis, with or without perforation, or diverticular hemorrhage. Episodes of acute diverticulitis present themselves with pain in the left or right lower quadrant, depending on the location of the diverticula. Patients may also exhibit fever or other non-specific symptoms like anorexia or nausea. This book provides a review of the symptoms, treatment options and long-term health outcomes of diverticular disease and diverticulitis. It also examines management strategies for acute complicated diverticulitis, and discusses diverticulitis of the right colon.

This concise book explains how to analyze endoscopic mucosal biopsies of the colon obtained for diagnosis and follow up of colitis in general and inflammatory bowel diseases (ulcerative colitis, Crohn’s disease and microscopic colitis) in particular. This is achieved by the presentation of basic lesions in multiple drawings together with an explanatory text and microscopic photographs. The description is completed by a review of various differential diagnostic issues and types of colitis. Colitis: A Practical Approach to Colon Biopsy Interpretation is aimed at general pathologists and pathologists in training and also gastroenterologists to help them understand how a precise diagnosis can be reached.

This easy-to-use atlas comprises a collection of representative common and unusual virtual colonoscopy (CT colonography, CTC) cases that physicians and radiologists may expect to encounter during their clinical practice. The atlas reflects the important recent advances in image acquisition, patient preparation, and image processing and is thus completely up-to-date. Each case is presented with the native CT images, integrated images obtained by 3D image processing, and colonoscopic correlation. Topics covered include normal appearances, anatomical variants, pitfalls, diverticula, lipomas, inflammatory bowel disease, polyps, flat lesions, cancers, and the postsurgical colon. By presenting the main features of anatomy and pathology, this atlas will serve as an invaluable tool both for radiologists performing CTC and for clinicians who need to review the CTC examinations of their patients.

This book offers an overview of the clinical applications of PET/MR imaging through a case-based format. Hybrid PET/MRI provides functional and anatomical information via one setting offering superior imaging quality with lower radiation dose being administered to the patient. The cases in this book focus on the use of this technique in the diagnosis of oncologic, neurologic, cardiovascular, infectious and inflammatory, and pediatric diseases. Each case is presented with the patient history, protocols, interpretation of findings, and pearls and pitfalls accompanied by high quality PET/MR images. The major strength of this book is the discussion of both MRI and PET findings pertinent to each particular case. It expands the discussion of oncologic applications of this modality through a variety of cases that highlight staging, treatment response, and follow up. Illustrating a spectrum of PET/MRI clinical applications, PET/MR Imaging: A Case-Based Approach is a valuable resource for radiologists, nuclear medicine physicians, and residents.

This book aims to familiarize readers with the most common acute surgery topics encountered in clinical practice and is unique in its use of infographics. It will be used in clinical rotations in surgery as a supplement to the knowledge gained, and will also provide instructors with a complementary tool, offering a wide-ranging guide to general aspects of acute surgery, with some hints on gynecologic and urologic emergencies. The book is intended to provide medical students and junior residents in medicine or surgery with a comprehensive and up-to-date overview of the most relevant operative techniques.

This book focuses on the diagnostic impact of CT scans in severe abdominal trauma and in non-traumatic acute abdomen, the two clinical entities that constitute the main reasons for referrals for this imaging technique from the intensive care unit. The concept behind it is that emergency surgeons and physicians not only need the clinical knowledge to manage the different pathological conditions, but that they must also have a full understanding of diagnostic imaging modalities. To this end, each chapter includes a description of a specific acute abdominal disorder. In addition to the clinical presentation and the diagnosis and management guidelines, there is a special focus on imaging studies with clear and concise descriptions, high-quality images and the evolution grading scale to aid interpretation. This easy-to-read book is an ideal source of practical information for acute care surgeons, radiologists and for all the members of the emergency team.

Over past several decades, an increasing number of cases of diverticulitis of colon have been reported making it a major health problem particularly in western countries. The distribution of the disease varies geographically with western population having prevalence rates of 5-45% and Asian population having prevalence rates of 13-25%. Although elderly people are more likely to develop diverticulitis, younger patients may also develop diverticular disease. In fact, it has been reported that disease in younger patients is more aggressive with higher rates of complication and recurrence. According to latest statistical reports acute diverticulitis accounts to nearly 200000 hospital admissions putting a burden of 2.7 billion dollars on healthcare system in America. Diverticular disease can cause significant symptoms, impair quality of life and can prove fatal if left untreated and is considered as the fifth most costly gastrointestinal disorder in the Western world. The book entitled, Diverticulitis; Diagnosis and Treatment, presents an up to date review of the medical and surgical management of diverticulitis. The book comprises of various topics discussing the background, epidemiology, etiology, pathogenesis, presentation, treatment both medical and surgical, and recent advances in the management of diverticulitis. The book will be academic interest for surgeons, physicians, gastroenterologists and Coloproctologists. The book can be used as a reference book by teachers, professionals and students.The main benefit of reading this book is that since this disease entity is common all over the world and its incidence is increasing and is a significant contributor of health care costs, all the relevant and latest information regarding this disease has been published in a comprehensive form which will be helpful to the students, academicians, researchers and professionals dealing with medical healthcare.
