Objective: To explore the analysis of pregnancy status and related risk factors after uterine laparoscopic surgery of EMT complicated with infertility. Methods: A total of 342 patients with EMT complicated with infertility,who underwent laparoscopic radical surgery in our hospital from January 2014 to June 2016 were selected as the observation group, 13 patients were lost during the follow-up period. According to whether the patients were pregnant two years after operation, the patients were divided into non-pregnancy group (n=124) and pregnancy group (n=205).The basic information of the two groups was compared for single factor analysis, and the significantly different single factors were analyzed by non-conditional logistic regression analysis, the influence factors for non-pregnancy and the forecast model were established. Results: Among the 329 patients with EMT, the incidence of non-pregnancy was 37.69% (124/329). The differences in age, duration of infertility, staging of endometriosis, type of infertility, tubal obstruction, adenomyosis, reproductive aids, administration of GnRH-a and fertility index of endometriosis were statistically significant (P<0.05). Logistic regression analysis showed age (OR=1.478, 95% CI:1.213~1.802), infertility time (OR=2.667, 95% CI:1.367~5.204), tubal blockage (OR=1.831, 95% CI:1.242~2.700), reproductive assistance technology (OR=0.417, 95% CI:0.281~0.619), endometriosis fertility index (OR=0.312, 95% CI:0.168~0.580) and secondary infertility (OR=2.252, 95% CI:1.525~3.327) were independent influencing factors of pregnancy (P<0.05), and logit(P)=-0.764+0.391X1+0.981X2+0.605X3-0.874X4-1.164X5+0.812X6, X1 representing age, X2 representing infertility time, X3 representing tubal blockage, X4 representing reproductive assistive technology, X5 representing endometriosis fertility index and X6 representing secondary infertility.Conclusion: Among the 329 patients with EMT complicated with infertility, the incidence of non-pregnancy was 37.69% (124/329). Age, infertility time, tubal blockage, reproductive assistant technology, endometriosis index and secondary infertility are the independent influencing factors of pregnancy. Clinical measures should develop targeted program to improve postoperative pregnancy rates according to the above indexes.
