Patient's question:
Tubal blockageDoctor's answer:
Fimbrial occlusion accounts for 10% to 25% of female tubal diseases. Recanalization of proximal tubal occlusion can be achieved through hysteroscopic COOK catheter recanalization or partial tubal resection and anastomosis. Hysteroscopic catheter recanalization involves inserting a COOK catheter into the interstitial part of the fallopian tube under hysteroscopy for tubal hydrotubation. The recanalization is facilitated by the separation, dilation effect of the catheter, and the impact of the fluid, which recanalizes the interstitial and isthmus parts of the fallopian tube. The surgical procedure is relatively simple but more expensive. Approximately 85% of proximal tubal obstructions can be resolved through proximal catheter dilation. However, postoperative pregnancy rates vary widely, ranging from 12% to 39%, with an ectopic pregnancy rate of 2% to 9%. For patients who cannot undergo catheter recanalization, partial tubal resection and anastomosis can be considered to locate and treat the obstruction.
