Investigation of prevalence for perioperative venous thromboembolism and risk factors of the present situation in Chinese adults patient with inguinal hernia(CHAT-1) / 中国实用外科杂志

ABSTRACT

OBJECTIVE: To investigate and analyze the current situation of inguinal hernia treatment and postoperative venous thromboembolism(VTE)events in Chinese adults. METHODS: From January 1, 2017 to December 31, 2017, the patients who were hospitalized with inguinal hernia in 58 large hospitals in mainland China were retrospectively analyzed by means of questionnaire. After data cleaning, all patients were stratified and statistically analyzed using Caprini score.RESULTS: A total of 14 322 questionnaires were received from 58 different hospitals. After data patching and data cleaning, a total of 13 886 questionnaires(97.0%) were retained in accordance with the standard. The ratio of laparoscopic surgery and open surgery was 51.2% and 48.8% respectively. A total of 16 VTE events were observed,accounting for 0.1%(95% CI 0.11-0.13). The incidence of VTE was 0.2%(95%CI 0.18-0.20) in the high-risk group and 0.02%(95%CI 0.01-0.03) in the middle-risk group. The incidence of VTE in the high-risk group was significantly higher than that in the middle-risk group(P=0.000). No VTE event was found in the low-risk group. Of all patients, only 3250(23.4%) underwent Caprini risk assessment,with 13.2% receiving any prevention, whether appropriate or not, and only 1.2% receiving appropriate prevention. CONCLUSION: The incidence of VTE event after operation of inguinal hernia in Chinese adults is severely underestimated, and has not been paid enough attention by surgeons at present.
