This clinical trial aims to determine whether perioperative goal-directed nutritional therapy can prevent postoperative pulmonary and other major complications in malnourished esophageal squamous cell cancer patients. Its main question is whether individualized nutritional therapy can improve short-term surgical outcomes and long-term prognosis. Researchers will compare goal-directed and conventional nutritional therapy to identify differences in morbidities and survival.
