Hysteroscopic Surgery in Treatment of Intrauterine Abnormalities

Study Overview
=================
Brief Summary
-----------------
With the ongoing developments in the field of hysteroscopy during the past 15 years, hysteroscopic surgery is becoming safer and less invasive for the patient. Improved technology has enabled surgeons to perform many operative procedures in an ambulatory setting without significant patient discomfort and with potentially significant cost savings. Office operative hysteroscopy (see and treat hysteroscopy) reduces the distinction between a diagnostic and an operative procedure, shifting the focus in health care away from inpatient diagnosis and treatment. The development of smaller-diameter hysteroscopes with continuous-flow system features and working channels, through which operative instruments can be introduced, has made it possible to treat some uterine and cervical diseases without the traditional need for cervical dilation or general anesthesia. Use of specially designed hysteroscopic 5F mechanical instruments (e.g., scissors, biopsy cup, graspers, and corkscrews) has long been the only way to perform operative procedures in an ambulatory setting. However, although grasping forceps and scissors are excellent for treating adhesions, cervical polyps, and endometrial polyps smaller than or the same size as the larger endometrial polyps, or thick lesions (e.g., submucous fibroids) were difficult to treat successfully using such miniature, fragile instruments and without cervical dilation. An important technologic advance occurred in 1997 with the introduction of a versatile bipolar electrosurgery system dedicated to hysteroscopy, the Gynecare VersaPoint (Ethicon, Inc., Somerville, NJ, USA), which represents a key point in the history of office operative hysteroscopy. With the use of 5F bipolar electrodes, the number of pathologic conditions treated using office operative hysteroscopy has increased tremendously, reducing the use of the resectoscope and the operating room to a smaller number of cases. More recently, a new generation of electrical generators, allowing the use of bipolar energy on miniaturized electrodes, has been presented (Autocon 400 II; Karl Storz Endoscopy, Tuttlingen, Germany). The main advantage of these instruments is that they are reusable, thereby reducing the costs of office operative as those described for the Versapoint system. The feasibility of ambulatory uterine surgery is not just dependent on recent technological advances in instrumentation such as miniaturization of equipment, but also the favorable anatomical characteristics of the uterus itself. The sensitive innervations of the uterus originate in the myometrium and extend to the outer serosal surface, whereas the endometrium and any fibrotic tissue within the cavity are less sensitive. Thus, procedures can be carried out without the use of analgesia or anesthesia. However, a careful operative technique is of paramount importance, in particular, avoiding inadvertent deep penetration of the superficial myometrium when resecting lesions such as polyps, maintaining the lowest possible distension pressures, and expediting procedures through efficient surgical techniques.
