Initial Experience of Articulating Laparoscopic Instruments for Benign Gynecologic Disease: A Single-Arm Multicenter Prospective Study (Korean Gynecologic Oncology Group 4002)

Laparoscopic surgery has evolved with technological advances in many aspects and increasing demand for its benefits in cosmetics, fast recovery, reduced complication rates and pain. However, it still possesses drawbacks such as limited surgical movement due to the nature of rigid laparoscopic instruments. In order to overcome such limitations, several laparoscopic jointed instruments have been developed. In this prospective multicenter, single-arm cohort study, we investigated the short-term safety and feasibility of the new articulating laparoscopic instruments in benign gynecologic surgery. A total of 113 patients who were diagnosed with benign gynecologic adnexal diseases underwent laparoscopic surgery with articulating laparoscopic instruments. Surgical outcomes, including intra/postoperative complication rates, operation time and estimated blood loss, as well as surgeon's subjective evaluation of the usage of the instruments, were evaluated. The results demonstrated that the articulating laparoscopic instruments had comparable usability and produced similar surgical outcomes to conventional laparoscopic surgery. The objective parameters, such as the operative time and complication rates, as well as the subjective parameters, such as the surgeon's own evaluation of the surgical instruments' usability, demonstrated potential benefits of the instruments in benign gynecological diseases. Overall, the study demonstrated that the use of this novel articulating device is feasible in gynecologic laparoscopic surgery.
