Health is defined not only as the absence of disease, but as a state of complete physical, mental and social well-being. Consequently, the evaluation of the quality of life should include these parameters. With the increase in survival rates of patients subjected to liver transplantation for end-stage liver disease or surgical resections for malignancies of the digestive system, much of the attention of health systems has focused on the quality of life of these patients after appropriate treatment. Several studies have assessed the physical, mental and social well-being of patients undergoing surgical treatment. In this review, we summarize what is known so far of the quality of life after liver transplantation, pancreatectomy, oesophagectomy, colectomy, hepatectomy or gastrectomy.
