title: HyCoSy--as good as claimed?
abstract: Hysterosalpingo contrast sonography (HyCoSy) has been compared favourably in the literature with hysterosalpingography (HSG). It does not require ionizing radiation and demonstrates the uterus and ovaries. HyCoSy is reported as being a safe, well tolerated, quick and easy investigation of Fallopian tube patency. Over a 1-year period HyCoSy was performed by two operators on 118 consecutive women who were thought likely to have patent Fallopian tubes. The examinations were graded using a local scale to assess discomfort and were correlated with tubal patency. HSG was performed on 116 patients by the same operators and discomfort recorded. 15 patients underwent both examinations. The degree of pain or reaction was graded 0 (no pain) to 4 (maximum) according to a locally devised scale. Costs of the two examinations were estimated. 89 patients examined by HyCoSy were graded 0-2. However, 23 had severe protracted pain and/or vasovagal reactions with bradycardia and hypotension. Of these, seven required resuscitation owing to prolonged symptoms, requiring treatment with atropine. 19 of the 23 had bilaterally patent Fallopian tubes. Where subsequent HSG was performed, tubal occlusion was confirmed in 8 of 15 women. Other pathologies were noted in 29 of the HyCoSy patients and there were six technical failures. During the same period no severe adverse reactions occurred in 116 patients having HSG performed by the same operators. Three of the HSG examinations were technically unsuccessful. Discomfort following HyCoSy was much greater than that reported previously. Possible mechanisms are discussed but it does not appear to be related to tubal occlusion. Diagnostic accuracy, costs and discomfort compare unfavourably with HSG.
