Pregnancy Outcome after Office Microhysteroscopy in Women with Unexplained Infertility

BACKGROUND Hysteroscopy offers diagnostic accuracy and the ability to treat uterine pathology. The current study aimed to review the findings and feasibility of the proposed office-based diagnostic and operative microhysteroscopy in previously diagnosed wom- en with unexplained infertility and to evaluate the post-microhysteroscopic pregnancy outcome in a-year follow-up period. MATERIALS AND METHODS This prospective controlled study was conducted between 2006 and 2013. Two hundreds women with unexplained infertility were randomized into two groups: A. study group including 100 women recruited for office micohysteroscopic session and B. control group including 100 without the proposed microhysteroscopic intervention. A malleable fiberoptic 2-mm, 0 and 30 degrees angled hysteroscopy along with an operative channel for grasping forceps, scissors, or coaxial bipolar electrode were used for both diagnostic and operative indications. The findings, complications, and patient tolerance were recorded. A-year follow-up of pregnancy outcome for both groups was also performed. RESULTS Seventy cases (70%) of patients had a normal uterine cavity. Twenty wom- en (20%) had endometrial polyps. Other pathology included submucous myomas in 3 cases (3%), intrauterine adhesions in 3 cases (3%), polypoid endometrium in 3 cases (3%), and bicornuate uterus in one case (1%). The pathological findings were treated in all patients without complication. Also a-year follow-up of the to- tal developing cumulative pregnancy rate (CPR) was evaluated in groups A and B (control). Group A revealed the total CPR of 28.5%, among which 25% in women without pathology, 40% in women with endometrial polyps, 23% in women with adhesions, 33% in women with polypoid endometrium, and 21% in those with bi- cornuate uterus. However, A-year follow-up of spontaneous pregnancy outcome in group B showed a total CPR of 15%. CONCLUSION Women tolerance, safety, and feasibility of simultaneous operative correc- tion make the proposed office microhysteroscopy an ideal and routine procedure in order to diagnose and to treat missed intrauterine abnormalities, especially in cases with un- explained infertility, with additional improvement of the pregnancy outcome after the procedure.
