This book gives in depth information of the pre and post operative management of patients undergoing gastrointestinal surgery, with emphasis on the care required to lessen the potential complications post operation. Patients having undergone surgery face a 10 per cent risk of adverse reaction to the treatment and certain gastrointestinal operations have a 50 per cent risk of postoperative complications, particularly among cancer patients. Consequently preventing complications from arising is of paramount importance. That's what this book sets out to do.
