Analysis of pregnancy outcome after anastomosis of oviduct and its influencing factors

Abstract

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.

Effectiveness of laparoscopic tubal anastomosis in tubal occlusion patients after laparoscopic salpingostomy for tubal pregnancy

“…Considering the associated factors, our findings suggest that the type of anastomosis significantly affects the pregnancy rate. A study suggested that pregnancy rates were higher after isthmus‐ampulla anastomosis of the oviduct compared with anastomosis at other sites of the oviduct 9,10 . However, our study indicates that the pregnancy rate was lower after isthmus‐ampulla anastomosis of the oviduct when compared with that after anastomosis at other sites.…”

Is there any difference between pregnancy results after tubal reanastamosis performed laparotomically, laparoscopically, and robotically?

“…26 In a study conducted on 156 patients who underwent laparoscopic reanastomosis, it was observed that the pregnancy rate was 81% in the first 6-year interval, 79% in the 6-10-year interval, and this rate was halved in the 10-year or longer interval. 27 In our study, when the time between sterilization and reanastomosis was compared, the pregnancy rate was 76.3% for 1-5 years, 55% for 5-9 years, and 40% for those who were sterilized more than 10 years ago. We think that if the time between sterilization and reanastomosis is less than 5 years, it increases the pregnancy rate.…”

“…In one of the other two studies, the pregnancy rate was reported as 91% between 1–5 years and 72% between 11–15 years, but the effect of the age factor on this rate was not evaluated 26 . In a study conducted on 156 patients who underwent laparoscopic reanastomosis, it was observed that the pregnancy rate was 81% in the first 6‐year interval, 79% in the 6–10‐year interval, and this rate was halved in the 10‐year or longer interval 27 . In our study, when the time between sterilization and reanastomosis was compared, the pregnancy rate was 76.3% for 1–5 years, 55% for 5–9 years, and 40% for those who were sterilized more than 10 years ago.…”

Tasa de éxito de embarazo post recanalización tubárica

“…El presente trabajo demostró que la tasa de concepción más alta fue en las pacientes entre 20 y 35 años al igual que en el estudio de Behera (11). El intervalo entre la salpingectomía y la recanalización tubárica fue mayor a 5 años en este trabajo y presentó una tasa de éxito del 24.6%, por el contrario, en el trabajo de Feng y cols el intervalo de tiempo entre el procedimiento de salpingectomía y el de recanalización tubárica fue entre 1 y 23 años con una media de 8.7 años y con una tasa de éxito del 67.9% (12).…”
