Combined hysteroscopic findings and 3-dimensional reconstructed coronal view of the uterus to avoid laparoscopic assessment for inpatient hysteroscopic metroplasty: pilot study.

Study Objective: To assess the use of 3-dimensional (3D) reconstructed coronal view of the uterus and intraoperative hysteroscopic findings to avoid diagnostic laparoscopy during inpatient hysteroscopic metroplasty.

Design: Pilot study (Canadian Task Force classification II).

Setting: University hospital infertility clinic.

Patients: Fifty-nine patients with recurrent abortion and double uterine cavity with 3D sonographic diagnosis of septate uterus undergoing inpatient hysteroscopic metroplasty.

Interventions: Inpatient hysteroscopic treatment of septate uterus without laparoscopic diagnosis. In addition to sonographic observations, 2 intraoperative hysteroscopic criteria were used to confirm the diagnosis: visualization of muscular fibers and myometrial blood vessels.

Measurements And Main Results: Operative parameters (operative time and fluid absorption), complications (incomplete resection and uterine perforation), requirement for a second intervention, and shape of the uterine cavity at hysteroscopic follow-up. In 56 of 59 patients (94.9%), intervention was performed without complications, and in 3 cases, intervention was suspended because of intraoperative suspicion of bicornate uterus. These 3 patients underwent laparoscopy, which confirmed the diagnosis of septate uterus. In all cases, incision was considered sufficient. Postoperative diagnostic hysteroscopy in all patients showed a normal cavity (fundal notch <1 cm).

Conclusions: Combined use of hysteroscopic confirming criteria and 3D sonography seems to be a reliable and simple strategy for characterizing the presence of septate uterus and to perform inpatient metroplasty usually without laparoscopic visualization of the uterine fundus.
