Under the guidance of the concept of fast tract surgery (FTS), peri-operative managements including pre-operative, intra-operative and post-operative treatments can be optimized to accelerate the rehabilitation of surgery patients. Post-operative recovery of gastrointestinal functions is one of the key links of FTS, in which Chinese medicine has certain features and advantages over it. Current assessments on post-operative gastrointestinal functions recovery include clinical and laboratory assessments, but there is still no industrial assessment received by all. The current situation of post-surgery assessment of peri-operative gastrointestinal functions was studied in this paper, and the research orientation of this field was analyzed and prospected.
