Laparoscopic Management of an Intrauterine Fallopian Tube Incarceration After Curettage for a Non-progressing Pregnancy

Study ObjectiveTo report and demonstrate a case of a laparoscopic repair of an intrauterine fallopian tube incarceration as complication of curettage.DesignA step-by-step explanation of the surgery using video (instructive video) (Canadian Task Force classification III).SettingUniversity Hospital Estaing, Clermont-Ferrand, France.PatientA 29-year-old woman experiencing a nonevolving pregnancy at 8 weeks underwent curettage. After 9 months, she complained of abnormal vaginal discharge. Ultrasound evaluation showed a right parauterine mass. She reported a maternal medical history of ovarian cancer in a context of Lynch syndrome. Magnetic resonance imaging revealed a right hydrosalpinx 12 mm in diameter, with a suspect fimbriae lesion of the tube and a 7-mm endometriosis nodule of the uterine torus.InterventionWe decided to explore the fallopian tube by laparoscopy and to perform hysteroscopy. A fallopian tube incarceration was suspected during hysteroscopy: a defect of the uterine wall was observed, through which there was protrusion of a tubal fimbriae. The laparoscopic view of the pelvis confirmed incarceration of the right fallopian tube through the uterine wall. It was carefully extracted out of the uterine defect, and the uterine wall defect was repaired with an X-point using Monocryl 1.Measurements and Main ResultsA tubal patency test was performed, which was positive on both sides. Because phimosis responsible for the hydrosalpinx had been treated, salpingectomy was not performed.ConclusionCurettage for miscarriage or undesired pregnancy is not exempt from complications, such as hemorrhage, simple perforation, and infection. Intrauterine fallopian tube incarceration is uncommon but can affect fertility. This diagnosis is important to avoid destruction of the fimbriae and necrosis of the tube and also to reduce the risk of ectopic pregnancy.
