〔Abstract〕 Objective To study the application value of modified Xiaochengqi Decoction in promoting the recovery ofgastrointestinal function after obstetrics and gynecology. Methods 90 patients with gynecological and obstetric surgery treated in Zhumadian Hospital of traditional Chinese medicine from November 2018 to November 2019 were randomly divided into observation group and control group, with 45 cases in each group. The control group was treated with conventional western medicine after operation, and the observation group was treated with modified Xiaochengqi Decoction on the basis of the control group. The anal exhaust time, postoperative defecation time, bowel sound return to normal time, intestinal dysfunction score and curative effect of the two groups were compared and analyzed. Results After treatment, the anal exhaust time and bowel sound recovery were lower than the control group, but there was no significant difference (P > 0.05); the observation group was lower than the control group, which was significant (P < 0.05). After treatment, bowel dysfunction scores decreased in both groups and significantly lower than the control group, statistically significant (P < 0.05); overall treatment efficiency in the observation group was 95.56%, significantly higher than 82.22%, and statistically significant (P < 0.05). Conclusion The soup can effectively promote the recovery of gastrointestinal function and improve the treatment efficiency.
