Article: Immediate versus delayed treatment of perimenopausal bleeding due to benign causes by balloon thermal ablation.[show abstract] [hide abstract]
ABSTRACT: To compare the effectiveness and safety of thermal balloon ablation without pretreatment with endometrium-thinning agents compared with delayed ablation with pretreatment for women with perimenopausal menorrhagia. Prospective, randomized, controlled trial (Canadian Task Force classification I). Hospital-based ambulatory medical center. Thirty women age 46 to 51 years with severe enough perimenopausal menorrhagia to make them candidates for either hysterectomy or endometrial ablation. Two patients with submucosal myomas and six who had undergone cesarean section were included. Thirteen patients were randomly assigned to be treated within 30 days and received a single intramuscular administration of gonadotropin releasing hormone (GnRH) analog; 17 women were allocated to be treated within 3 days of enrollment without uterine preparation. A thermal balloon was inserted transcervically under general anesthesia, and after inflation in the endometrial cavity with 5% dextrose in water, was heated to 87 degrees C for 8 minutes. Immediate and long-term major and minor complications and success rates were analyzed. Bleeding patterns and mean duration of menstrual flow were compared between groups at 6-month follow-up. No major intraoperative or postoperative complications occurred in either group, including the women who had recently undergone hysteroscopic myomectomy or had a history of cesarean section. Minor side effects were similar in both groups, and did not exceed 5%. Overall, at 6-month follow-up, 7 women were amenorrheic, 20 hypomenorrheic, and 3 eumenorrheic. No significant differences were noted between women treated with immediate or delayed ablation in either the distribution of bleeding patterns or days of flow per cycle (mean +/- SEM 1.8 +/- 0.42 vs 2.1 +/- 0.75 days, respectively). This pilot study suggests that prompt treatment of perimenopausal menorrhagia with thermal balloon endometrial ablation is as effective and safe as deferred therapy combined with GnRH analog as an endometrium-thinning agent. In light of our results, the theory that previous cesarean section and presence of small submucosal myomas constitute relative contraindications for the procedure merits further consideration.

ABSTRACT: Our objective was to define a subset of women with postmenopausal bleeding in whom the accepted practice of endometrial sampling could be safely omitted. Vaginal endosonographic measurements were compared to the histological findings of curettings following diagnostic dilatation and curettage in 129 women with post-menopausal bleeding who were not receiving hormonal therapy. Atrophy was diagnosed in 49%, slight proliferation in 10%, endometrial polyps in 11%, hypoplasia in 12%, and adenocarcinoma in 12%. Endometrial atrophy was associated with a mean sonographic thickness of 2.6 mm of the double layer (range 0-6.5 mm). Of the women with a final histological diagnosis of atrophy, 92% had an endometrial thickness of 3 mm or less. Furthermore, all women with a sonographic endometrial thickness of 3 mm or less had atrophic endometrium (p < 0.0001). An endometrial thickness of 3 mm or less would have reduced the number of dilation and curettage procedures by 45% and no cases of endometrial pathologies would have been missed. In women presenting with postmenstrual bleeding, meticulous scanning of the endometrium can select a group where endometrial sampling can be omitted from the protocol.Ultrasound in Obstetrics and Gynecology 11/1993; 3(6):426-8. · 3.01 Impact Factor
Article: Gradual cervical dilation for termination of early second-trimester pregnancy with a double balloon device.[show abstract] [hide abstract]
ABSTRACT: Thirty-two women with pregnancies of 12-15 weeks underwent cervical dilation before abortion using a double balloon device. In all cases, satisfactory dilation was achieved and evacuation accomplished. The slow dilation process, resulting from the continuous indirect dilator effect of the balloons, was not associated with patient inconvenience in most cases. Larger dilation was achieved by adding a continuous instillation of extraovular prostaglandin E2 solution through the device. The double balloon device is a convenient and safe cervical dilator and may be a suitable method for cervical dilation before abortion.Obstetrics and Gynecology 01/1992; 78(6):1142-6. · 4.73 Impact Factor
