Core Tip

Core Tip: For surgeons, to understand the general aspects of how the site and extent of gastrectomy affect postoperative patient’s quality of life (QOL) is important. Therefore, we investigated this concern by the nationwide multi-institutional collaborative study called Postgastrectomy Syndrome Assessment Study. The overview of the effects of the six main gastrectomy procedures on the patient’s dairy living revealed that the postoperative QOL differed greatly depending on the site and extent of gastrectomy. The severity and characteristics of postgastrectomy syndrome should be considered to select gastrectomy procedures, overcome surgical shortcomings, and enhance postoperative care.
