Hysteroscopic cannulation for proximal tubal obstruction: a change for the better?
OBJECTIVE
To compare overall the results of hysteroscopic tubal cannulations and resection anastomosis for proximal tubal occlusion.


METHODS
Nonrandomized retrospective analysis of patients operated on by two surgeons.


METHODS
University and large tertiary referral private practice.


METHODS
Seventy-four patients over a 10-year period, with bilateral or unilateral proximal occlusion of a single tube.


METHODS
Hysteroscopic cannulation, resection anastomosis, or both.


METHODS
Intrauterine and ectopic pregnancy rates, long-term tubal patency, and pathology of tubal segments.


RESULTS
In patients with normal distal tubes, intrauterine pregnancy rates were similar (12/21, 57% versus 12/24, 50%) and ectopic pregnancy rates were lower (0/21, 0% versus 7/24, 29.1%) in the cannulation group. One-year patency rates in nonpregnant patients was higher in the anastomosis group (12/15, 80% versus 3/8, 33%).


CONCLUSIONS
Hysteroscopic cannulation should be first choice in the management of proximal tubal obstructions in selected patients. It may be a treatment option for delayed occlusion after successful cannulation or resection anastomosis.
