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

Cases We reported five patients with unilateral or bilateral tubal discontinuity between the ampulla and fimbria, occasionally detected through laparoscopy combined with hysteroscopy at the Reproductive Hospital Affiliated to Shandong University from 2017 to 2023. Three cases were observed to have this malformation on the left fallopian tube, one cases on the right side, and one case bilaterally. None of these cases were combined with urological malformations. Outcomes After surgery there was one instance of postoperative delivery, one ongoing pregnancy and three not yet conceived. Conclusion 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 potential improving pregnancy outcomes.
