More DescriptionThe incidence of upper gastrointestinal cancer, particularly gastric and esophageal cancer, is higher in Japan than in any other country and is most likely related to dietary factors. As a result, more resections are performed for these diseases in Japan than in other countries. Japan is internationally known to be taking the initiative in upper gastrointestinal cancer surgery. However, despite most patients who have undergone surgery suffering from a number of long-term symptoms associated with postoperative dysfunction, systematic methods of assessment or support still remain to be established, except for a few articles which have reported that postoperative dysfunction significantly affects patients' quality of life (QOL). To that end, a top priority has been the establishment of a scale enabling the objective assessment of post-operative dysfunction in these patients. Contributors have been working on the development of the first scale in the world for assessing post-operative dysfunction in patients who have undergone upper gastrointestinal surgery. The name of the scale "DAUGS" is named after the Dysfunction After Upper Gastrointestinal Surgery. This book will deepen and broaden international scientific exchange and help improve the QOL of patients after upper gastrointestinal surgery.
