Laparoscopic myomectomy in premenopausal women with and without preoperative treatment using gonadotrophin-releasing hormone analogues.

Abstract

The present study was undertaken in order to evaluate the usefulness or otherwise of preoperative gonadotrophin-releasing hormone (GnRH) analogue treatment prior to laparoscopic myomectomy. From June 1993 through December 1996, 60 premenopausal women aged between 25 and 42 years and with a sonographic diagnosis of intramural or subserous myomas were selected for laparoscopic myomectomy at the Department of Obstetrics and Gynaecology of the Catholic University of The Sacred Heart, Rome. According to a computer-generated sequence, 30 patients were submitted to three cycles of GnRH analogue treatment prior to surgery, whereas no preoperative treatment was prescribed to the other 30 patients. Laparoscopic myomectomy was successfully performed in all patients for a total of 174 myomas excised laparoscopically. The patients' mean age, the number of myomas per patient, the mean diameter of the myomas, parity and estimated blood loss were similar in both groups. The operative time was significantly longer in the group of patients submitted to GnRH analogue treatment than that of the group of patients not submitted to any preoperative medical therapy (157.5±74.71 versus 112.33±54.71 min; P = 0.01). No intra-operative complications occurred. In no case was blood transfusion necessary. Two patients developed post-operative fever (temperature >38°C.). The mean length of hospital stay was 2.39 days and was similar in both groups. Thirteen spontaneous pregnancies occurred among 24 infertile patients (54.1%). The pregnancy rate for these patients was similar in both groups. The viable term delivery rate was 45.8%. The authors conclude that laparoscopic myomectomy is a feasible and safe procedure. The post-operative pregnancy rate for infertile patients is similar to that following laparotomic myomectomy. The present study suggests that preoperative GnRH analogue treatment does not offer any significant advantages for laparoscopic myomectomy.
