[Efficiency of saline contrast hysterosonography for evaluating the uterine cavity].

Abstract

Diagnostic hysteroscopy is the standard investigation performed in the case of abnormal vaginal blood loss. More recently there has been increasing interest for minimal invasive saline contrast hysterosonography (SCHS) as this technique is less painful and less expensive. SCHS is indicated in case of abnormal uterine bleeding (premenopausal and postmenopausal), bleeding while using tamoxifen, suspicion of a congenital uterine abnormality and Asherman's syndrome. As well as intracavity abnormalities (polyps and myomas) SCHS can also be used to evaluate the intramural extension of myomas, which is necessary to assess whether hysteroscopic resection is possible. The sensitivity and specificity of SCHS for demonstrating intracavity abnormalities (with a prevalence of 54%) are 94% (95%-CI; 91-97) and 89% (95%-CI: 85-94) respectively. The positive and negative predictive values are 91% (95%-CI: 87-95) and 92% (95%-CI: 89-97) respectively. SCHS has a short learning curve and can be performed in an outpatient setting. SCHS fails more frequently in postmenopausal women than premenopausal women (12.5% vs. 4.7%; p = 0.03). The chance of a non-conclusive SCHS is 7.6% and is higher if the uterine volume is greater than 600 cm3 (relative risk: 2.63; 95%-CI: 1.05-6.60) and if two or more myomas are present: (RR 2.65; 95%-CI: 1.16-6.10). SCHS is 2 to 9 times cheaper than diagnostic hysteroscopy. It can replace 84% of the diagnostic hysteroscopies. SCHS, in combination with endometrial sampling, whenever indicated, might be able to replace diagnostic hysteroscopy as gold standard in the evaluation of the uterine cavity.
