Abstract    Microecosystem with important physiological functions are dynamically colonized in the human gut，which plays an important role in the health of the host and is a key factor in activating and maintaining intestinal physiological functions.In surgery， a considerable number of patients are bound to be affected by intestinal microbiota due to the fundamental changes in intestinal function and physiological structure. But in the course of clinical nutrition treatment， long-term fasting， application of antacids and the stress of the disease itself can lead to the destruction of micro-ecosystems. Concomitant intestinal infections， antibiotic resistance and so on increase the risk of treatment and prolong the length of stay. Therefore， in the context of the growing importance of gut microecology， how to correct the disturbance of intestinal flora， protect the gut barrier and accelerate the recovery in the surgical nutrition treatment is a concern.

Key words: micro-ecological, gut barrier, nutrition therapy
