Imaging of Gastrointestinal Tract Tumors describes current imaging practice for the most commonly encountered benign and malignant digestive tract tumors and gives a review of the literature for less frequent tumors. General features (anatomic data, frequency, clinical and biologic signs, treatment) are discussed for all pathologies prior to description of imaging techniques, which include barium studies, ultrasonography and angiography, and above all CT. MRI appears particularly indicated for esophageal carcinoma and pelvic recurrences of colorectal cancers. The book is divided into three main section - benign tumors, malignant tumors, and tumors with an indeterminate prognosis - reflecting the value of different imaging strategies as a function of a tumor's natural history. The thorough analysis of literature for both frequent and less common tumors allows global evaluation of the diagnostic possibilities of imaging techniques, making Imaging of Gastrointestinal Tract Tumors a reference work for all specialists concerned with digestive tract pathologies.

The past 20 years have seen a surge of research into colorectal cancer, which is a reflection of the need to improve our methods of treating patients suffering from this increasingly common form of cancer. Greater knowledge of the basic mechanisms involved in colorectal carcinogenesis is an essential prerequisite to improvements in cancer prevention. In this volume the editors have brought together an impressive list of experts to cover the epidemiology, pathophysiology, morphology and basis for new diagnostic and therapeutic approaches to early detection and prevention. This broad scientific approach provides the reader with up-to-date review of our current state of knowl­ edge of colorectal carcinogenesis and indicates how this information can be used to generate more research and create new opportunities for diagnosis and treatment. This is a book of knowledge and ideas, some of them still at the stage of theoretical interest, but others with practical potential for the care of patients. I recommend it to those who have a research interest in colorectal carcinogenesis, as well as to readers who wish to know just how far medical scientists have progressed in their efforts to achieve the ideal of cancer prevention.

Colorectal Surgery: Living Pathology in the Operating Room is two books in one. First, it is an atlas in the classic definition: each chapter is a two-page spread discussing one case. Functionally, each chapter is a case study with both the surgical and pathological perspectives beautifully rendered and fully explained. Visually, every chapter presents the reader with operative and/or diagnostic photos, and anatomic line drawings by the author. The text, more extensive than in many atlases, provides a concise yet complete operative record: patient history/work up, anatomic anomalies, the procedure itself, pathologic findings, and follow up. Key teaching points emphasize the most important and unique aspects of every case. Residents, fellows, and even seasoned practitioners will gain valuable diagnostic and therapeutic insights from this material. The case study presentation provides an excellent review tool for the American Board of Colon and Rectal Surgeryexam.
