BACKGROUND: The advent of flexible CO2 laser fiber to gynecology arena might represent a turning point in the use of laser energy on a large-scale basis in gynecological surgery. However, there might be some concerns regarding the degree of surgical skills required to use the flexible system. The purpose of our study is to evaluate whether flexible CO2 laser fiber is technically accessible.
METHODS: Fourteen residents in Obstetrics and Gynecology without surgical experience attending laparoscopic box training with both flexible CO2 laser fiber and traditional line-of-sight CO2 laser using Lumenis AcuPulse Duo CO2 laser (Lumenis, Yokne’am Illit, Israel) were prospectively enrolled. Participants were tested at sequential time points on specific surgical tasks and results obtained with the flexible CO2 laser fiber and the traditional line-of-sight CO2 laser were compared. Results were compared by means of paired t-test and a two-tailed P value <0.05 was considered significant.
RESULTS: Mean grading at the beginning of training were similar between flexible fiber and line-of-sight CO2 laser. At the end of training, significant improvement in surgical skills was obtained for both techniques, with a statistically significant higher grading for flexible fiber CO2 laser compared to line-of-sight CO2 laser.
CONCLUSIONS: Our study found that residents without surgical experience show better skills with the flexible CO2 laser fiber delivery system compared to the standard line-of-sight CO2 laser system after a two-month training period with gynecological laparoscopic box. According to our results, flexible CO2 laser fiber delivery system is technically accessible and holds a potential in gynecological surgery.
