Over the last two decades, there have been major advances in imaging, endoscopy, and laparoscopy in the field of Gastrointestinal (GI) surgery. GI surgery is the newest sub-specialty branch of general surgery, where enhanced expertise and high-volume centres have made a difference in the outcomes of complex operations. Surgeons can now do difficult procedures with low morbidity and mortality rates, and greatly improved overall results. This volume provides detailed and up-to-date information on diseases of the appendix, colon, and rectum. It covers the anatomy, surgical and non-surgical approaches to different conditions, dedicated chapters on rectal and colon cancer, plus current and future surgical techniques. Written and edited by experts in the field, this book will be a valuable resource for specialist surgeons and trainees, general surgeons, researchers, and medical students.
