Background
Salpingotomy may change the anatomical structure and patency of the fallopian tube, which may affect the fallopian function. This study is to investigate the clinical efficacy of preliminary hysteroscopic tubal hydrotubation (HTH) after laparoscopic salpingotomy for tubal ampullary pregnancy.
Methods
A retrospective study was carried out, 140 women underwent laparoscopic salpingotomy for ampullary pregnancy from March 2013 to March 2017. Some patients received HTH in the 1st month and hysterosalpingography (HSG) in the 3rd month after salpingotomy (HTH group; n = 95), and some patients only received HSG in the 3rd month after salpingotomy (control group; n = 45). Clinical data, tubal patency and fertility outcome were evaluated after follow-up of 15 months.
Results
The tubal patency rate of the operated side was significantly higher in the HTH group than that in the control group (89.47% vs 68.89%, P < 0.05). The intrauterine pregnancy (IUP) rate was significantly higher in the HTH group (76.47% vs 51.11%, P < 0.05), and the recurrent ectopic pregnancy rate in the operated side was significantly lower in the HTH group than in the control group (9.41% vs 22.22%, P < 0.05). Logistic regression analysis showed that the positive factor for IUP was HTH (OR = 3.109, 95% CI 1.439–6.714, P = 0.004), while the negative factors were history of pelvic inflammatory disease (PID) (OR = 0.167, 95% CI 0.074–0.377, P < 0.001) and history of tubal infertility (OR = 0.286, 95% CI 0.113–0.723, P < 0.05).
Conclusion
Preliminary HTH after laparoscopic salpingotomy for ampullary pregnancy could improve reproductive function and lead to a better fertility outcome. Patients without history of PID or tubal infertility may be the most suitable ones for HTH after salpingotomy.
