Therapeutic hysteroscopic procedures

Abstract

Hysteroscopy has evolved from a diagnostic procedure into a therapeutic method for a variety of conditions. Instruments specifically designed for hysteroscopic operative procedures have improved. The indications for therapeutic hysteroscopy are increasing and its proper applications can improve patient's gynecologic care. These facts should stimulate the gynecologist to become proficient with hysteroscopy for diagnosis and the treatment of many intrauterine abnormalities. In selected patients there are major advantages including the avoidance of a laparotomy with the potential sequelae that can follow operations requiring entrance into the peritoneal cavity. The operative techniques have been refined and, with experience, good postoperative results and low morbidity have become evident. The septate uterus can be treated by hysteroscopic metroplasty with improved reproductive outcome. Symptomatic submucous myomas in selected patients can be removed hysteroscopically. Lysis of intrauterine adhesions has become the standard method of therapy. Foreign bodies lost in the uterine cavity or embedded IUDs can be removed atraumatically under direct vision. As the approach to intrauterine problems is refined, other applications are being investigated such as tubal cannulation, endoscopic chorionic villus sampling, and application of hysteroscopy to new reproductive technologies such as the placement of gametes in the fallopian tubes. Because of the simplicity of approaching the uterotubal ostia transcervically, hysteroscopy remains in the front line of investigation as a possible approach for inducing tubal occlusion as a permanent or temporary method of contraception. Finally, laser energy is being used in patients with intractable uterine bleeding to photocoagulate the endometrium and to create amenorrhea by means of inducing severe intrauterine adhesions.
