Changes in the Plasma ADH Level During and After Surgery for Esophageal Cancer

It is well known that surgical stress produces hypersecretion of antidiuretic hormone (ADH) and oliguria [1, 2]. However, there has been little study of the relationship between plasma ADH level and urine volume under surgical stress. The purpose of this study is (1) to analyze the factors causing the elevation of plasma ADH level during surgery and (2) to investigate the relationship between plasma ADH level and urine volume by measuring plasma ADH level of patients undergoing surgery for esophageal cancer and gastric cancer.
