Leading experts in the fields of gastroenterology, surgery, and radiology comprehensively review the pathophysiology, diagnosis, management, and treatment of acute bleeding disorders of the GI tract. The authors break down acute bleeding into upper and lower GI tract sources and provide a differential diagnosis for each disease, evidence-based algorithms for clinical practice, treatment modalities for its management, and standards of care. The authors outline the many dilemmas faced by physicians in their approach to their patients, such as localization of the bleeding source (upper vs lower), the need and timing for emergency endoscopy, and the timing for radiologic intervention and/or surgery.

Colorectal cancer is the third most common malignancy in the United States and the third leading cause of cancer mortality in both men and women. As gastroenterologists and primary care physicians are faced with patients with colorectal cancer, the future road to decreasing these numbers begins with increased knowledge and awareness of the effects that biology, genetics, environment, and lifestyle have on the disease. In "Early Detection and Prevention in Colorectal Cancer", Dr. Karen Kim and her esteemed contributors take a comprehensive look into the world of colorectal cancer and the ways that today's physician can positively impact the patient's outcome. Unique features include: novel screening modalities; disparities in colorectal cancer; latest information on genetic testing for colorectal cancer; screening algorithms for average and high risk patients; and economics of screening and prevention. Some chapter topics include: Colonic carcinogenesis; Environmental factors and colorectal cancer; Chemoprevention of colorectal cancer; Biomarkers and colorectal cancer; and Health policy and colorectal cancer prevention. With cutting-edge technology and information, "Early Detection and Prevention in Colorectal Cancer" should be in the hands of all gastroenterologists, primary care physicians, and those in training. Only by understanding the biology and genetics of this disease, and the effects that environment and lifestyle have on it, can gastroenterologists truly make a difference with the treatment of their patients.
