title: Multicenter feasibility study of a new coaxial falloposcopy system.
abstract: We compared falloposcopy employing a new coaxial system with traditional laparoscopic chromotubation and hysterosalpingography in a prospective, multicenter clinical trial at five tertiary infertility centers. Based on findings at hysterosalpingography or laparoscopic chromotubation, the 16 women (22 tubes) in group 1 had a presumed diagnosis of proximal tubal obstruction, and the 4 (7 tubes) in group 2 had unexplained infertility. Cannulation was successfully achieved in 83.3% of tubes. In group 1, 85% (17/20) of visualized tubes were patent and 35% (7/20) were normal. In group 2, 40% (2/5) of visualized tubes were abnormal. Management was changed in 52.4% of women as a result of falloposcopic findings. Falloposcopy with this new coaxial system allows improved visualization with less bulky and less traumatic instruments. The system provides valuable information regarding the fallopian tube lumen that correlates poorly with that obtained with more traditional techniques.
