In recent years, epidemiological studies have shown a significant increase of incidences regarding ulcerative colitis (UC) in most regions of the world. At present, a common therapeutic modality for inflammatory bowel disorders is the use of anti-inflammatory agents, including sulfasalazine and acetylsalicylic acid, steroid hormone, and other immunosuppressive agents. Most of these treatments are symptomatic and palliative because the etiology of the disease is not yet established. As a result of no proper drug available to treat UC, patients with UC are at a high risk of developing colitis-associated cancer (CAC). It is necessary to understand the genetic and molecular mechanisms involved in the pathogenesis of UC and CAC that lead to the path of new drug discoveries. Diagnostic and Treatment Methods for Ulcerative Colitis and Colitis-Associated Cancer provides innovative insights that describe the fundamental understanding of UC and CAC and the molecular mechanisms behind the etiology as well as modern diagnostic methods that are employed in UC and CAC. Current prevention and therapeutic strategies practiced in the pre-clinical level are also discussed. The content within this publication examines alternative medicine and dietary intervention and drug delivery techniques. It is designed for healthcare professionals, physicians, academicians, researchers, R&D organizations, and medical students involved in drug discovery and clinical and therapeutic research.
As the number of patients with colitis-associated cancer (CAC) is on the increase, the purpose of this book is to review the latest topics concerning management of the disease. In recent years, the diagnostic power of endoscopy and molecular pathology has also grown tremendously, as a result of which they now have a far greater influence on the treatment of CAC. At the moment, appropriate monitoring programs for ulcerative colitis and Crohn’s disease remain uncertain. At the same time, the latest findings on DNA methylation and microRNAs hold the promise of making revolutionary changes in these areas. Moreover, recent drug advances in the treatment of inflammatory bowel diseases have changed surgical indications. On the other hand, the indication of mucosectomy on colorectal cancer in ulcerative colitis and prophylactic abdominoperineal resection for Crohn’s disease remain controversial. This book provides the latest information on the remaining issues of CAC from the point of view of expert surgeons.
Now published in two volumes to accommodate new chapters on the many advances in understanding and treatment options, this volume represents the definitive reference on inflammatory bowel disease, a spectrum of diseases that is receiving increasing attention as our understanding of the etiological factors increases and diagnostic tools are refined. Basic research accelerated at the beginning of this decade and is now yielding new, more targeted treatments than were available just a few years ago. Volume 1 is on IBD and Ulcerative Colitis, and Volume 2 is on IBD and Crohn's Disease. All areas that were covered in the second edition have been expanded and updated. New sections include one addressing etiology and pathophysiology of IBD, including environmental influences and effect of age at onset, and one with a focus on aggravating factors in the IBD patient such as infectious agents, non-steroidal anti-inflammatory drugs, and pregnancy.
This book conjoins the latest advances on the use of endoscopy to diagnose, monitor, and treat patients with inflammatory bowel disease. Chapters include the historical use of rigid sigmoidoscopy, non-interventional imaging procedures, and the correlation of pathology and endoscopic visualization. This is the first book to include individual chapters in gastroenterology, colorectal surgery, and IBD texts, the preeminent role of endoscopic imaging in the management of chronic ulcerative colitis, and Crohn's disease. It also includes chapters on capsule endoscopy and balloon and overtube-assisted enteroscopy to define the presence and activity of Crohn's enteritis and additional chapters defining the use of random biopsies versus chromoendoscopy, and computer enhanced imaging to define possible dysplasia development. The book also includes access to online videos, making it the ultimate verbal and visual tool for all medical professionals interested in the advances in the field over the last several decades. Endoscopy in Inflammatory Bowel Disease is a concise text that is of great value to practicing endoscopists, gastroenterologists, general or colorectal surgeons, physicians in training, and all medical professionals caring for patients with inflammatory bowel disease.
During the past decade, the medical and surgical treatment of ulcerative colitis has undergone dramatic advances, including the widespread use of immunomodulators, biological drugs, and restorative proctocolectomy. In order to correctly balance the risks and benefits of medical therapies and surgical procedures, there is a need for improved diagnosis of colonic disease, acute complications, extraintestinal manifestations, and early and delayed postoperative complications. Cross-sectional imaging techniques are therefore playing an increasing role in the assessment of ulcerative colitis and provide an essential complement to clinical data and endoscopy. This practical, illustrated volume on the role of cross-sectional imaging is aimed at radiologists, gastroenterologists, and surgeons who are engaged or interested in the diagnosis and care of patients with inflammatory bowel disease, particularly ulcerative colitis. After an overview of diagnostic imaging techniques, state-of-the-art assessment of colorectal inflammatory disease with CT colonography using water enema is discussed, followed by description of the plain radiographic and CT findings in patients with acute exacerbations and surgical complications. Subsequent chapters review the diagnostic findings and role of cross-sectional imaging in the assessment of sclerosing cholangitis (with emphasis on MR cholangiopancreatography), vascular complications (particularly portal and mesenteric thrombosis), associated neoplasms, such as colorectal cancer and abdominal desmoids, and perianal inflammatory disease. Normal postoperative appearances and early and delayed complications in patients treated with proctocolectomy and ileal pouch-anal anastomosis are also comprehensively reviewed.
Ulcerative colitis (UC) is a chronic inflammatory disease that affects the colon. According to the literature, some thirty percent of UC patients may require a subtotal colectomy and ileostomy due to failure of medical treatment, acute toxic colitis or dysplasia/cancer diagnosis. Some patients choose to get continence restored with either an ileorectal anastomosis (IRA) or an ileal pouch-anal anastomosis (IPAA). Worldwide most surgeons prefer an IPAA to an IRA, despite reports of pouchitis, impaired fertility and fecundity. Fear of recurring proctitis and fear of rectal cancer in the remaining rectum is contributing to the choice of an IPAA. Little is known regarding the outcomes of IRA compared with IPAA in UC patients. We aimed to investigate the anorectal function, quality of life (QoL), risk of failure and rectal cancer in patients with UC restored with IRA and IPAA respectively. Methods: Data about all Inflammatory bowel disease (IBD) patients was obtained from the Swedish National Patient Register (NPR) between 1964-2014 and in one study from the Linköping University Hospital medical records 2006-2012. Patients who developed cancer were identified from the Swedish National Cancer Register. We investigated the risk of cancer and inflammation, functional outcome and failure as well as the quality of life for IRA and IPAA patients. Investigation of risk for cancer in IRA and IPAA compared with the background population was performed using survival analytic techniques: uni-and multivariate regression, Kaplan Meier curves and standardized incidence ratio. Results: Twelve percent (7,889 /63,795) of UC patients required colectomy according to the NPR. The relative risk for rectal cancer among patients with an IRA was increased (SIR 8.7). However, the absolute risk was 1.8% after a mean follow up of 8.6 years and the cumulative risk 10- and 20-years after IRA was 1.6% and 5.6%, respectively. Risk factors for rectal cancer were primary sclerosing cholangitis in patients with an IRA (hazard ratio 6.12), and severe dysplasia or cancer of the colon prior to subtotal colectomy in patients with a diverted rectum in place (hazard ratio 3.67). Regarding IPAA, the relative risk to develop rectal cancer was (SIR 0.4) compared with the background population and the absolute risk was only 0.06% after a mean of 12.2 years of follow up. Among patients operated at the Linköping University Hospital: IRA patients reported better overall continence according to the Öresland score with in median3 (IQR 2–5) for IRA (n=38) and 10 (IQR 5–15) for IPAA (n=39, p<0.001). There were no major differences regarding the QoL. According to the NPR, after a median follow up of 12.4 years failure occurred in 265(32%) out of 1112 patients, of which 76 were secondarily reconstructed with an IPAA. Failure of the IPAA occurred in 103 (6%) patients with primary and in 6 (8%) patients after secondary IPAA (log-rank p=0.38). Conclusion: IRA is a safe restorative procedure for selected UC patients. Patients should be aware of the annual postoperative endoscopic evaluation with biopsies as well as the need to the use of local anti-inflammatory preparations. However, IRA should not be offered for UC patients with an associated primary sclerosing cholangitis diagnosis due to the increased risk to develop rectal cancer in their rectal mucosa. In such case, IPAA is probably the treatment of choice.
