Abstract:
Transcervical tubal cannulation using tactile guidance has a similar rate of successful cannulation compared with that with US guidance (78% versus 73%) but takes less time to perform (2.3 +/- 1.8 minutes versus 8.7 +/- 6.2 minutes, mean +/- SD) and is associated with less pain and bleeding. This appears to be because of the design of the Labotect tubal cannulation set that uses a special speculum and tenaculum to straighten the uterus before insertion of the guide cannula and a less traumatic ball-tipped guide catheter.
