BackgroundThis study aims to investigate the influencing factors of pregnancy after laparoscopic oviduct anastomosis.MethodsThe data of 156 cases of laparoscopic oviduct anastomosis in our hospital were analyzed.ResultsThe pregnancy rate decreased with age (P < 0.005). The pregnancy rate after six years of anastomosis was higher in those with ligation (P < 0.005). The postoperative pregnancy rate significantly increased in subjects with oviduct lengths of > 7 cm (P < 0.01). The pregnancy rate of isthmus end-to-end anastomosis was higher (P < 0.005). The pregnancy rate after bilateral tubal recanalization was higher than that after unilateral tubal recanalization (P < 0.005). The pregnancy rate after laparoscopic tubal ligation and laparoscopic anastomosis was higher than that of open tubal ligation and laparoscopic anastomosis (P < 0.005).ConclusionThe pregnancy rate after laparoscopic oviduct anastomosis is higher in subjects below 35 years old, with a ligation duration of < 6 years, and a length of oviduct of > 7 cm, and those who underwent isthmus anastomosis and laparoscopic oviduct ligation and recanalization.
Objective: This study aims to investigate the clinical efficacy of laparoscopy and hysteroscopy in the treatment of tubal-factor infertility (TFI) to provide a basis for predicting postoperative pregnancy rates.Methods: The clinical data of 336 patients who underwent laparoscopy and hysteroscopy for TFI between February 2018 and December 2018 in the Department of Reproductive Gynecology at the First People's Hospital of Yunnan were retrospectively analyzed. After implementing the inclusion and exclusion criteria, 278 patients were included in the study. The patients were grouped according to pelvic adhesions, hydrosalpinx, twisted fallopian tubes, and fimbriae structure. The impact of the extent of fallopian tube diseases on postoperative pregnancy outcomes was analyzed.Results: Of the 278 patients, 129 got pregnant (pregnancy rate = 46.4%). Pelvic adhesions, hydrosalpinx, twisted/folded fallopian tubes, and damage to the fimbriae of the fallopian tubes were found to affect the natural pregnancy rate after surgery, and it decreased significantly with the aggravation of the disease (P < 0.001). Of the 129 patients who had natural pregnancies, 29 had ectopic pregnancies (ectopic pregnancy rate = 22.48%). Twisted/folded fallopian tubes and damage to the fimbriae structure significantly increased the incidence of postoperative ectopic pregnancy (P < 0.001).Conclusion: Laparoscopy and hysteroscopy are effective treatments for TFI. Pelvic adhesions, twisted/folded fallopian tubes, hydrosalpinx, and damage to the fimbriae of the fallopian tubes can affect postoperative pregnancy outcomes and lead to failure of a natural pregnancy after the operation. The incidence of ectopic pregnancy increases with the degree of fallopian tube twisting/folding and the degree of damage to the fimbriae of the fallopian tubes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
