Abstract:
Objective:To explore the risk factors for tubal patency after partial salpingectomy and end-to-end anastomosis,and their impact on pregnancy outcomes.Methods:A total of 300 patients with tubal pregnancy who underwent partial salpingectomy and end-to-end anastomosis in Zhengzhou Maternal and Child Health Hospital from January 2020 to April 2023 were enrolled in the study.Hysterosalpingography was performed after surgical treatment to examine the tubal patency.Lasso-Logistic regression was used to analyze the risk factors for postoperative tubal patency,and Spearman's correlation was used to analyze the impact of each risk factor on the pregnancy rate.Results:Hysterosalpingography showed that the fallopian tube was not obstructed in 225 cases(unobstructed group),the tube was not completely patent(n=54)or blocked(n=21)(obstructed group).Univariate analysis showed that age,diameter of the tubal pregnancy sac,location of tubal pregnancy,timing of surgery,pelvic adhesion,anastomotic method,length of remaining tubal,history of pelvic surgery,number of intraoperative electrocoagulation,intraoperative blood loss,and experience of surgeons were factors affecting postoperative tubal patency(all P＜0.01).Lasso regression analysis identified location of tubal pregnancy,pelvic adhesion,anastomotic method,length of remaining tubal,history of pelvic surgery,number of intraoperative electrocoagulation,and experience of surgeons as influencing factors.Multivariate Logistic regression analysis showed that tubal isthmus pregnancy,pelvic adhesion,open anastomosis surgery,history of pelvic surgery,and number of intraoperative electrocoagulation were independent risk factors for postoperative tubal patency,while length of remaining tubal and years of surgeon's work experience were independent protective factors for postoperative tubal patency(all P＜0.01).A total of 295 patients were followed up for 1 year,192 cases(65.08%)were pregnant,including 172 cases of intrauterine pregnancy(89.58%)and 20 cases of ectopic pregnancy(10.42%).Spearman correlation analysis showed that tubal isthmus pregnancy,pelvic adhesion,open abdominal anastomosis surgery,pelvic surgery history,and times of intraoperative electrocoagulation were negatively correlated with postoperative pregnancy,while the remaining tubal length and years of surgeon's working experience were positively correlated with postoperative pregnancy rate(all P＜0.01).Conclusions:For tubal patency of patients after partial salpingectomy combined with end-to-end anastomosis,the history of tubal isthmus pregnancy,pelvic adhesion,open abdominal anastomosis,pelvic surgery,and the number of intraoperative electrocoagulation are independent risk factors,which are negatively correlated with postoperative pregnancy.The remaining tubal length and the years of surgeon's work experience are independent protective factors,which are positively correlated with postoperative pregnancy.
