Es. Surrey et al., MULTICENTER FEASIBILITY STUDY OF A NEW COAXIAL FALLOPOSCOPY SYSTEM, The Journal of the American Association of Gynecologic Laparoscopists, 4(4), 1997, pp. 473-478
We compared falloposcopy employing a new coaxial system with tradition
al laparoscopic chromotubation and hysterosalpingography in a prospect
ive, multicenter clinical trial at five tertiary infertility centers.
Based on findings at hysterosalpingography or laparoscopic chromotubat
ion, the 16 women (22 tubes) in group 1 had a presumed diagnosis of pr
oximal tubal obstruction, and the 4 (7 tubes) in group 2 had unexplain
ed infertility. Cannulation was successfully achieved in 83.3% of tube
s. 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 abnorm
al. Management was changed in 52.4% of women as a result of falloposco
pic findings. Falloposcopy with this new coaxial system allows improve
d visualization with less bulky and less traumatic instruments. The sy
stem provides valuable information regarding the fallopian tube lumen
that correlates poorly with that obtained with more traditional techni
ques.
