Wire guide cannulation alone is no treatment of proximal tubal occlusion.
Tubal catheterization procedures have become standard of care as a primary treatment of proximal tubal occlusions. They successfully utilize a variety of catheter techniques, though all usually include a wire guide. This raises the question whether guide wire catheterizations alone can be used to treat proximal tubal occlusions. We therefore investigated consecutively 25 women with at least one proximally occluded oviduct by attempting wire guide cannulations bilaterally in 10 and unilaterally in 12 women with two tubes and in three women with a single tube. Among the 10 patients with bilateral occlusion, seven were recanalized bilaterally (70%), one unilaterally (10%) and two not at all (20%). Among the 15 patients with unilateral tubal occlusion, 12 (80%) were recanalized. In total, 27 out of 35 (77%) obstructed oviducts were recanalized. In a follow-up period of 5-17 months only one pregnancy was, however, recorded and this was a tubal pregnancy. We conclude that wire guide cannulation of proximally obstructed tubes achieves tubal patency in a large percentage of cases, comparable to other catheter techniques reported in the literature. In contrast to those, however, wire guide cannulations alone result in much lower pregnancy rates. This observation strongly suggests that wire guides, used with co-axial and balloon catheter systems, are not responsible for the pregnancy success reported for these procedures. Wire guide cannulation alone does not therefore represent adequate treatment for patients with proximally occluded Fallopian tubes.
