Iw. Scudamore et al., FALLOPOSCOPIC COMPARISON OF UNILATERAL AND BILATERAL PROXIMAL TUBAL OCCLUSIVE DISEASE, Human reproduction, 9(2), 1994, pp. 340-342
The purpose of this study was to compare the appearance of the entire
length of the oviductal canal in women with unilateral versus bilatera
l proximal tubal occlusion. Eleven women had apparent unilateral disea
se and 18 had apparent bilateral occlusion. Proximal occlusion was con
firmed both by hysterosalpingography and laparoscopy. Falloposcopic ex
amination was performed by retrograde visualization using the linear e
version catheter, in office. Bilateral apparent proximal occlusion was
found to have a significantly higher incidence of actual proximal occ
lusion and distal intralumenal abnormalities. However, five proximal s
egments and six distal segments were found to be abnormal where the pr
e-examination diagnosis was unilateral occlusion. Furthermore, the con
tralateral oviductal canal was found to be abnormal in four women with
apparent unilateral disease, indicating that apparent unilateral prox
imal tubal occlusion is associated with actual pathology. These data d
emonstrate the value of intralumenal assessment of apparent proximal o
cclusion.
