Analysis of the occurrence of interstitial pregnancy during the re-pregnancy after modified tubal resection or ligation

Abstract

Objective: To investigate the effect of modified tubal resection or ligation on the incidence of interstitial pregnancy during the re-pregnancy. Methods: Patients who underwent tubal resection or ligation in our hospital from June 2017 to June 2019 were selected as research subjects and randomly divided into observation group and control group, with 43 cases in each group.The observation group received modified tubal resection or ligation, while the control group received traditional tubal resection or ligation, and the occurrence of re-gestation interstitial pregnancy was followed up. Results: A total of 86 subjects were included, with an average age of (32.3±2.6) years old, 2-5 pregnancies, and 2-4 births. There was no statistical difference in general data between the two groups.The success rate of operation in both groups was more than 95%, with 6.98% (3/43) patients in the observation group having temporary fever and other discomforts after operation, and 9.30%(4/43) patients in the control group having good outcomes.In the observation group and the control group, 36 and 34 patients underwent in vitro fertilization and embryo transfer three months after the operation, respectively, and 23 pregnancies were successful in each group. All pregnancies in the observation group were intrauterine, and no ipsilateral tubal interstitial pregnancy occurred; in the control group, 19 were intrauterine pregnancies, and 4 cases of ipsilateral tubal interstitial pregnancy occurred.Ipsilateral tubal interstitial pregnancy after modified tubal ligation was significantly lower than that after traditional tubal resection or ligation (χ(2)=4.195, P=0.041). Conclusion: Modified tubal ligation and resection can effectively reduce the occurrence of interstitial pregnancy during the re-pregnancy.
