The incidence of fallopian tube patency after transcervical resection of the endometrium including rollerball diathermy to the tubal ostia

ObjectiveTo evaluate the incidence of tubal patency as well as the shape of the endometrial cavity after transcervical resection of the endometrium.DesignAn open observational trial.SettingThe obstetrics and gynecology unit at a district hospital in Norway.PatientsFifty consecutive patients who had undergone treatment for menorrhagia and metrorrhagia by resection of the endometrium and coagulation of the tubal ostium were included in the study.InterventionA hysterosalpingogram was performed with a semistiff catheter and injection of 20 mL contrast dye 5 to 12 months after transcervical resection of the endometrium and fibroids.Main outcome measuresTubal patency and uterine cavity morphology.ResultsForty-four patients showed total occlusion of the fallopian tubes, and the uterine cavity showed fibrosis and narrowing of the cavity. Three patients showed bilateral and three patients unilateral tubal patency.ConclusionShrinkage and fibrosis of the uterine cavity occur after endometrial resection. A significant number of women after transcervical resection of the endometrium have patient tubes (13%) despite coagulation of the tubal ostia.
