OBJECTIVE: The purpose of this study was to compare the long-term efficacy of the levonorgestrel intrauterine system and transcervical resection of the endometrium in the treatment of menorrhagia.
METHODS: This study was an open, randomized 3-year trial. Patients with menorrhagia were assigned randomly to either the levonorgestrel intrauterine system (n = 30) or endometrial resection (n = 29). Pictorial blood loss assessment charts were used to measure menstrual blood loss. A pictorial blood-loss assessment chart score exceeding 75 (representing menstrual blood loss
60 mL) was used to diagnosis the patient as having menorrhagia. Discontinuations and cases requiring repeat operations were evaluated.
RESULTS: Pictorial blood loss scores decreased from a baseline median of 261.5 (range, 601503) to 7 (range, 0101; P < .001) for the levonorgestrel intrauterine system and from 311 (range, 812506) to 4 (range, 0182; P < .001) for transcervical resection of the endometrium. Nineteen women of 30 using the levonorgestrel intrauterine system completed the 3-year follow-up compared with 22 of 29 for transcervical resection of the endometrium.
CONCLUSION: Both treatments efficiently reduced menstrual bleeding. The high continuation rate suggests that the levonorgestrel intrauterine system is comparable with transcervical resection of the endometrium.
