Although our practice does follow our patients who have had conizations (and no subsequent full term pregnancy) with regular cervical length ultrasounds, Maggie's patient was 32 weeks on 2/1, and the case in point occurred last week. Since she made it to 39-40 weeks, she would not have benefitted by cervical surveillance or cerclage! She made it to term despite all our technologies! She made it to 39 weeks. She doesn't have cervical incompetence.

I don't think anyone suggested pushing forward with a stenotic os; however, having had many women w/ scarring due to cryos or cones, once the scar tissue is broken up (and I have only done this digitally), the cervix opens quite promptly to 3, 4, 5 cm as Dan has suggested. And then the dilatation progresses quite normally.

I agree that persistence in labor in the face of a stenotic, scarred external os is not wise...regardless of prior c/s or not. One primip had a posterior sacculation of the uterus, with the fetus coming thru the posterior LUS because it was the "line of least resistance". This fetus was approximately +3 station and a paper thin LUS, the obstetrician was consulted and (eventually) believed me that this woman was closed, not completely dilated. But it took a spec exam since the uterus was so thin. C/S was uneventful.

Another woman w/ previous c/s and cryo since last birth was admitted in labor w/ stenotic os which we could not break up digitally. Had c/s w/ a window.

I thank those posters who gave suggestions for breaking up this scar tissue. I would certainly attempt this the next time I am faced w/ cervical stenosis. An automatic c/s without attempt at correcting the stenosis is *not* a benign procedure, and the techniques presented here would not cause any undue delay.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit.
