Background and purpose Abdominal surgery is the main department of gynaecology operation. Accelerating the recovery of gastrointestinal function after surgery can not only make patients early recovery diet, but also can reduce the common complications such as pelvic adhesion. It’s important to the rehabilitation and prognosis of patients. The Chinese medicine has been proven to accelerate the recovery of bowel function after the gynecologic abdominal surgery. Most of the indicators used to evaluate gastrointestinal motility recovery are scattered, and there is no standardized evaluation criterion so far. We found that there is not a scale for evaluating the gastrointestinal motility in perioperative period after reviewing a large number of literatures. The Postoperative Clinical Evaluation Criteria for Gastrointestinal Motility (PCECGM) became the local standard of Guangdong province (DB44/t 1581-2015) issued by the quality supervision bureau of Guangdong province in 2015, and a clinical evaluation now is necessary. Study design Cohort study (Diagnostic); Level of evidence, 2. Methods This prospective study was performed in the department of gynecology department at the Guangdong Province Traditional Medical Hospital from Mar. 2015 and Jun. 2017. Patients who diagnosed with benign lesion after laparoscopic total hysterectomy were included in this study. The purpose of this research was to evaluate reliability, validity and responsiveness of the PCECGM. Results 202 patients were included in this study, and the response , completion rate, complete time of the scale were 100%, 99.01% and（95.49士16.69）min, showing the good acceptability. The Cronbach’s Alpha coefficient and spearman-brown were 0.62 and 0.71 respectively. KMO is 0.58, and Bartlett's Test of Sphericity is 181.01, P<0.001. Two factors were extracted according to the factor analysis, and the cumulative contribution rate is 56.33%. The total score of the patients after treatment was significantly higher, P<0.001, and standardized effect value and standardized reaction mean were all 1.32, indicating a high degree of reactivity. Conclusions The properties of “Postoperative clinical evaluation criteria for gastrointestinal motility” are acceptable. It is an effective tool for the evaluation of gastrointestinal motility after the gynecologic abdominal surgery. Introduction Perioperative gastrointestinal dysfunction refers to the perioperative gastrointestinal function of all aspects such as sports secretion defense digestion absorption excretion disorders or weakened. Gastrointestinal motility disorder is the main cause of postoperative gastrointestinal dysfunction. At present, there is no uniform standard for postoperative gastrointestinal motility evaluation in clinical practice. It’s important to the rehabilitation and prognosis of patients. The Postoperative Clinical Evaluation Criteria for Gastrointestinal Motility (PCECGM) became the local standard of Guangdong province (DB44/t 1581-2015) issued by the quality supervision bureau of Guangdong province in 2015.
