Gastrointestinal failure is a kind of severe systemic inflammatory response, and often complicated with multiple organ dysfunction syndrome. Integrated traditional Chinese and Western medicine have a better curative effect in treating it. This study collected the famous veteran TCM physician Yu Guoyou's 175 prescriptions for treating 89 cases of gastrointestinal failure, calculated the frequency of traditional Chinese medicines and their categories, and analyzed the medication regularity with system clustering method, so as to summarize Yu's frequently used drugs and prescriptions. The results showed the top three most frequently used drugs aremagnolia bark, bitter orange, and rhubarb, which are components of Xiaochengqi decoction; Among the traditional Chinese medicines, medicines of tonifying deficiency, regulating qi, clearing heat, eliminating phlegm and dissipating dampness are most commonly used. Among the tonic medicines, those for tonifying Qi accounted for 2/3, which was the largest proportion; At the same time, some new prescriptions and new drug combinations were excavated and could be used as the reference for clinical medication. According to the findings, when differentiating syndromes of gastrointestinal failure, Yu regards the spleen and stomach Qi deficiency as the root cause and the heat toxin, blood stasis, Qi stagnation and dampness as the symptoms. In the treatment of gastrointestinal function failure, Yu gives priority to strengthening spleen, regulating Qi and purgation, prescribes medicines for dissolving blood stasis and detoxication, dissipating dampness, clearing heat and eliminating phlegm according to syndrome types. In other words, the treatment is based on syndrome differentiation, and the prescription is modified according to symptoms. In particular, Yu attaches importance to stomach-Qi recuperation and gastrointestinal function recovery in the process of treatment.
