The Aveta hysteroscopic tissue removal system showed significantly higher resection efficiency than other morcellation devices in a simulated fibroid model. This improved efficiency may lead to shorter operative times and better outcomes in hysteroscopic myomectomy procedures.
Area of Science:
- Gynecologic surgery
- Minimally invasive procedures
- Urogynecology
Background:
- Hysteroscopic myomectomy is a common procedure for treating uterine fibroids.
- Efficient tissue removal is crucial for operative success and minimizing complications.
- Existing hysteroscopic morcellation devices vary in their resection efficiency.
Purpose of the Study:
- To evaluate the resection efficiency of the Aveta hysteroscopic tissue removal system.
- To compare the Aveta system's performance against three established hysteroscopic morcellation devices.
- To utilize a standardized synthetic fibroid model simulating dense leiomyoma tissue.
Main Methods:
- Prospective, multicenter comparative bench study.
- Simulated hysteroscopic fibroid resections performed by 91 Ob/Gyn physicians.
- Four systems tested: Aveta Flex, MyoSure Reach, MyoSure XL, and TruClear DTSP.
- Resection efficiency measured as mass of fibroid analog removed (g/min).
Main Results:
- Aveta Flex demonstrated the highest resection rate (0.506 g/min).
- Aveta Flex significantly outperformed MyoSure Reach (0.184 g/min), MyoSure XL (0.274 g/min), and TruClear DTSP (0.389 g/min).
- Statistical analyses confirmed significantly higher resection rates for Aveta Flex (p < .005).
Conclusions:
- The Aveta Flex system exhibits superior resection efficiency compared to established hysteroscopic morcellation devices.
- Higher efficiency may positively impact operative duration and complete resection rates.
- Findings suggest potential improvements in hysteroscopic myomectomy workflow and outcomes.
