Technical results of falloposcopy for infertility diagnosis in a large multicentre study.
Despite increasing evidence of its potential clinical value, falloposcopy has not yet found widespread use. In a large prospective international multicentre study we investigated the hypothesis that limited technical reproducibility may be of crucial significance in this regard. From 1994 to 1998, data on 367 patients with 639 tubes were recorded from 18 centres (median number of falloposcopies 22). Falloposcopy was performed using hysteroscopic ostium access, coaxial tubal cannulation and retrograde visualization under laparoscopic control. The procedure was successful in 69.6% of the tubes. Failures occurred in 6.1% during hysteroscopy, in 10.6% during the cannulation step and in 16.4% during visualization. While predominantly intracavitary pathology or thick endometrium were found to interfere with hysteroscopic ostium access, technical insufficiencies resulting in catheter damage or vision disturbing light reflexions were identified to be responsible for most cannulation and visualization failures, confirming the importance of these factors. The number of patients who received a complete falloposcopic evaluation did not exceed 57%. Additionally, 23.7% of patients may have profited from unilateral success depending on the individual indication. As a consequence of these technically limited results it was concluded that the method currently qualifies for selected indications rather than for routine clinical application.
