Analysis of spontaneous pregnancy outcome in patients with fallopian tube infertility after hysteroscopy and laparoscopy

ObjectiveTo analyze the spontaneous pregnancy outcomes in patients with different types of fallopian tube infertility after hysteroscopy and laparoscopy.

MethodsA total of 226 cases with fallopian tube infertility were analyzed retrospectively.According to the location and side of tubal obstruction, it was divided into unilateral proximal tubal obstruction, bilateral proximal tubal obstruction, unilateral proximal and unilateral distal tubal obstruction, unilateral distal tubal obstruction, bilateral distal tubal obstruction and incomplete tubal obstruction.Proximal intubation, umbrella end colostomy, umbrella end molding and pelvic adhesiolysis were used, and at least one fallopian tube was unobstructed after operation.The spontaneous pregnancy outcomes in patients with different types of tubal infertility within one year after operation were compared.

ResultsThere was no significant difference in pregnancy rate among patients with unilateral proximal obstruction, bilateral proximal obstruction, unilateral distal obstruction, bilateral distal obstruction and incomplete obstruction(P>0.05).Among 226 patients, 192 cases with pelvic adhesions were found.The clinical pregnancy rate of mild and severe pelvic adhesion was 46.7% and 16.3%, respectively, the difference of which was statistically significant(P < 0.01).The clinical pregnancy rate was 27.5% in patients under 35 years old and 3.8% in patients over or equal to 35 years old, the difference of which was statistically significant(P < 0.01).The clinical pregnancy rate was 37.5% in patients with less than 2 years of infertility, 21.8% in patients with 2-5 years of infertility, and 14.3% in patients with more than 5 years of infertility, the difference of which was statistically significant(P < 0.05).

ConclusionsIt is feasible for patients with different types of fallopian tube infertility to receive corresponding surgical treatment, and there is no significant difference in postoperative pregnancy.Patients with severe pelvic adhesion have a low postoperative pregnancy rate and are not suitable for expectant pregnancy.Age and infertility duration may be independent factors affecting postoperative pregnancy.
