Objective To use data mining technology to analyze the prescription pattern of acupoint selection for postoperative intestinal obstruction treated by acupuncture in modern literature, so as to provide theoretical reference for acupuncture clinical data. Methods The Chinese Journal full-text Database, Wanfang data Resource system and VIP Journal full-text Database were searched, and the literatures about intestinal obstruction after acupuncture treatment from the establishment of the database to October 2020 were searched. After strict screening according to the inclusion criteria and exclusion criteria, MicrosoftExcel and Apriori algorithm in SPSSClementine software were used for information mining and analysis. Results The top 5 acupoints for intestinal obstruction after acupuncture treatment were Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan; the top 3 meridians of acupoints were foot Yangming stomach meridian, Ren meridian and foot Taiyin spleen meridian; in terms of acupoint compatibility, the combination of Tianshu and Zusanli had the highest frequency and the degree of support was 61.67%. When the three acupoints are compatible, Zusanli, Zhongwan, Tianshu or Zusanli, Shangjuxu and Tianshu are the most commonly used, and the degree of support is 40.00%. Conclusion There are certain rules to be followed in the selection of points and prescription of acupoints in the treatment of postoperative intestinal obstruction by acupuncture. This study can provide certain data support for the regulation of the selection and prescription of acupoints in the treatment of postoperative intestinal obstruction by acupuncture.
