WHAT IS HYSTEROSCOPY

The concept of video endoscopy concerns the use of a scope (endoscope), which may be hard or flexible, in order to view, diagnose or perform surgical procedures by using minimally invasive techniques for organs or cavities which present or not a via natural opening.

Video hysteroscopy is currently considered to be the preferred method (gold standard) for the investigation of uterine cavity and cervical canal.

• Diagnostic Video Hysteroscopy (TUSS: 40201155) uses a scope enveloped in a steel casing with an internal space which allows the passage of light and CO2.

• Surgical Video hysteroscopy with targeted biopsy (TUSS 31303170) allows a better accuracy for the evaluation of focal lesions, being performed on outpatients in the majority of the cases. This procedure uses a scope with a smaller diameter (2,9mm) and a steel casing (Bethochi) with two conduits: one for the scope and the fluid (generally a 0.9% saline), for distension and continuous flushing of the cavity, considering the fact it may present bleeding during the procedure, and other for the proper tweezers for targeted biopsy and/or scissors for the lysis of small lesions.

• Surgical Video hysteroscopy with use of resectoscope (TUSS 31303188) presents a set of steel casings called working element (which has the light provided from a Xenon light source, coupled with an optical fiber light cable); the resection loop and the cable for the passage of electric current coupled to a device with: monopolar energy (uses glycine or sorbitol mannitol solutions) and/or bipolar energy (uses a 0.9% saline.)

A distension medium for the cavity is mandatory, since the uterine cavity is virtual and its view is only possible after its secure distension through a power injection, which allows the performance of procedures such as: endometrial ablation, myomectomy, polypectomy, lysis of synechiae and septoplasty.
