Future research and developments in hysteroscopy.

Hysteroscopy has become an important tool to evaluate intrauterine pathology. In most cases, the pathology can be diagnosed and treated in the office or outpatient setting. The ability to use normal saline as a distending medium allows the procedure to be performed using bipolar energy. During hysteroscopic myomectomy, visualization can remain unobstructed with the use of a hysteroscopic morcellator. Its use is also associated with decreased operating time. The use of Essure(®) to block the proximal fallopian tube by a hysteroscopic approach is an approved procedure for tubal sterilization. However, it has been increasingly used to prevent hydrosalpinx fluid from entering the uterine cavity in women undergoing in vitro fertilization. The hysteroscopic approach has also been used to treat a variety of conditions such as treatment of interstitial pregnancy, caesarean scar pregnancy and retained placenta. However, the number of cases is still relatively small, and no randomized trial has ever been conducted. One of the potentially important developments is the use of falloposcopy to obtain distal tubal cytology as a screening for ovarian cancer. The technique remains to be refined.
