Congenital interruption between the ampulla and fimbria of the fallopian tube: case report.

ABSTRACT

We reported 5 patients with unilateral or bilateral tubal discontinuity between the ampulla and fimbria, occasionally detected through laparoscopy combined with hysteroscopy at the Reproductive Hospital Affiliated with Shandong University from 2017 to 2023. Three cases were observed to have this malformation on the left fallopian tube, 1 case on the right side, and 1 case bilaterally. None of these cases were combined with urological malformations. After surgery, there was 1 instance of postoperative delivery, 1 ongoing pregnancy, and 3 not yet conceived. The congenital ampulla and fimbria interruption of the fallopian tube may be independent of other significant deformities of reproductive or renal tracts. However, it can lead to hydrosalpinx and primary or secondary infertility. Surgical management options, such as salpingostomy, salpingectomy, and tubal ligation, have shown the potential to improve pregnancy outcomes.
