Hysterosalpingography before and after myomectomy: clinical value and imaging findings.
OBJECTIVE
Myomectomy is being performed increasingly for the treatment of menorrhagia and infertility. The purpose of this study was to describe the findings at hysterosalpingography before and after myomectomy and to correlate the findings with the operative technique and observations at surgery. This study also examined the value of hysterosalpingography in planning surgery, as well as in detecting postoperative complications and residual fibroids.


METHODS
The study group comprised 32 patients who were consecutively referred for hysterosalpingography after myomectomy. The indications for myomectomy were infertility in all cases, associated with menorrhagia in 20, pelvic pain in 15, and urinary frequency in eight. Eighteen of the 32 patients also had hysterosalpingography before surgery. The hysterosalpingographic findings were reviewed without knowledge of the clinical findings and then correlated with surgical and pathologic findings.


RESULTS
Preoperative hysterosalpingograms showed enlargement and/or distortion of the uterine cavity in 13 of 14 patients who had submucous fibroids or mural fibroids with a submucous component (mural/submucous fibroid). Cornual asymmetry was seen in seven of 18 patients, the result of an adjacent fibroid deforming one bilaterally in another two. In all four patients, tubal patency was shown after myomectomy. Intracavitary filling defects consistent with submucous or mural/submucous fibroids were found in 12 of 18 patients. After myomectomy, these defects resolved in eight cases; in the remaining four, persistent filling defects suggested residual submucous enlargement of the uterine cavity in only two of 32 patients; in both, residual mural and/or submucous fibroids were shown on sonography after surgery. Major distortion of the cavity after surgery was found in four patients; it was caused by filling defects consistent with residual submucous fibroids in two and by major synechiae in two. Diverticula at the site of resection of submucous fibroids were found in six patients. Major synechiae were found in two patients, resulting in unilateral or bilateral tubal occlusion.


CONCLUSIONS
Hysterosalpingography before myomectomy can assist the surgeon in planning the surgical approach by showing the presence, size, and location of submucous fibroids and concomitant tubal disease. Hysterosalpingography after myomectomy shows residual fibroids and complications of surgery, such as synechiae and diverticula, that may affect further treatment.
