Hysteroscopy as an investigation tool in recurrent implantation failure in vitro fertilization.

OBJECTIVES: To evaluate the use of hysteroscopy in the assessment of uterine pathologies in infertile women with repeated implantation failure (RIF) after in vitro fertilization (IVF) and determine whether removal of such pathologies increased pregnancy rates in women with RIF.

METHODS: This prospective study was conducted at King Fahd Hospital of the University, Al-Khobar, Kingdom of Saudi Arabia, between January 2010 and December 2015. The inclusion criteria were women who underwent IVF treatment cycles and ended in more than 2 RIF, and women who underwent hysterosalpingography (HSG). Hysteroscopies were performed, findings were recorded, and the clinical pregnancy rates were compared and assessed in patients with and without uterine cavity abnormality. All hysteroscopic procedures were performed by a single consultant.

RESULTS: Hysteroscopies were performed on 266 women who  had at least 2 RIF. The average duration of infertility was 7.2±3.1 years. In 162 patients (60.9%), a hysteroscopy did not find any abnormality of the uterine cavity. In 104 patients (39.1%) there were one or more abnormal hysteroscopic findings. Hysterosalpingography was able to detect only 54 abnormalities (51.9%). The pregnancy rate was significantly higher in patients who were treated by a hysteroscopy for a detected uterine abnormality (39.4%).

CONCLUSION: A hysteroscopy was able to detect intrauterine pathologies which were missed by other investigative modalities. We believe patients with a history of RIF should undergo hysteroscopic examination before any further cycles are considered.
