Hysteroscopic myomectomy: Long-term effects on menstrual pattern and fertility

Objective: To determine the effects of hysteroscopic myomectomy on menorrha gia and infertility and the influence of intramural extension on surgical f easibility and long-term outcomes. Methods: We studied 108 women who had first-line hysteroscopic resection of submucous pedunculated (n = 54), sessile (n = 30), or intramural (n = 24) leiomyomas over 7 years at an academic department specializing in endoscopi c surgery. Results: The mean (+/- standard deviation) operating time and distension me dium deficit were 18 +/- 7 minutes and 204 +/- 276 mt in the pedunculated l esion group, 23 +/- 9 minutes and 278 +/- 269 mt in the sessile lesion grou p, and 32 +/- 8 minutes and 335 +/- 272 mt in the intramural lesion group, respectively. More than one procedure was required to complete myoma remova l in 14 (26%) of 54, eight (26%) of 30, and 12 (50%) of 24 subjects in the pedunculated, sessile, and intramural lesion groups, respectively. After a mean follow-up of 41 months, myomas recurred in 27 subjects, with a 3-year cumulative rate of 34%. Twenty women had recurrent menorrhagia, with a 3-ye ar cumulative probability of 30%. The 3-year cumulative probability of conc eption was 49% in women with pedunculated lesions, 36% in those with sessil e lesions, and 33% in those with intramural lesions. The study had 80% powe r to detect five- and three-fold increases in menorrhagia recurrence and co nception rates, respectively, in the mainly intramural myoma group compared with the completely or mainly intracavitary myoma group. Conclusion: Hysteroscopic resection of submucous myomas gives satisfactory menorrhagia control and limited recurrence, but the benefit for infertility was less impressive. Myoma intramural extension did not have a substantial influence on any of the long-term outcomes but affected operating time and the number of procedures needed for complete removal.
