Hysteroscopic myomectomy: our experience and review

Abstract

Objective: To analyze the results of hysteroscopic myomectomy in our center and to compare the results to those published in the literature.

Methods: We performed a retrospective study of the clinical histories of patients who had undergone hysteroscopic myomectomy with a resectoscope between January 1992 and December 1999. Procedures were performed at a hysteroscopic clinic in the Department of Obstetrics and Gynecology at the University Public Hospital in Madrid's south zone. One hundred twenty pre-, peri-, and postmenopausal women with submucous myomas were included in the study. All patients underwent hysteroscopic resection with a monopolar loop.

Results: We performed 120 hysteroscopic myomectomies. The patients' median age was 44.8 years (23 to 74). Abnormal uterine bleeding (AUB) was the most frequent indication (84.1%). Inability to reproduce was the indication in 14 (11.6%) cases. GnRH analogue preparation was used in 60% of cases. We operated on 52 (43.3%) type 0, 51 (42.5%) type I, and 17 (14.1%) type II myomas, according to Wamsteker and Blok classification. A median of 32.5 (10 to 105) minutes was required for the interventions. The myomectomy was combined with another operation (12 polypectomies, 24 endometrial resections, and 1 laparoscopic ovarian cystectomy) in 32 patients. The median retention of glycemia was 281 cc (0 to 1300). We could not complete the resection in 22 patients. Twelve underwent reoperation (3 hysterectomies and 9 second myomectomies). No serious complications occurred, and the median hospital stay was 25.4 hours. The histological study confirmed leiomyoma in all the cases. The intervention results were satisfactory after a follow-up period of 12 months to 7 years, AUB being controlled in 88.5% of the patients.

Conclusion: Hysteroscopic myomectomy is a reliable procedure that is effective in controlling abnormal uterine bleeding. It is a good alternative to hysterectomy and has an acceptable surgical time and minimum hospital stay. To reduce the need of reintervention, appropriate patient selection and improved technique are necessary. The technique also offers significant economic savings compared with the conventional surgical methods.
