新しい子宮鏡手術機器「Intrauterine BIGATTI Shaver（IBS^®）」―その使用経験と可能性の考察―

抄録

　We describe our experience and modifications regarding the surgeries conducted with the hysteroscopy called Integrated Bigatti Shaver (IBS®). The rigid shaving system consists of two hollow reusable metal tubes fitting to each other. The inner tube rotates within the outer tube. The rotating and oscillating movement of the inner blade of the shaving system cuts the tissue and allows aspiration of specimens for histology. A correct fluid balance is calculated to maintain optimal distension and visualization inside the uterine cavity. Normal saline solution used for irrigation is inexpensive and economical.

　From March 2020, we have performed hysteroscopy with the IBS®. Unlike the conventional resectoscopy, the main advantage of the IBS® is that the tissue chips or adhesions were effectively removed without any thermal injury occurring on the endometrium. The thermal damage of healthy endometrium should be avoided in view of reproduction.

　Further investigations are needed to determine its utility for patients whose fertility preservation is requested.
