RESUMO
OBJECTIVES: Myomas are defined as benign tumours that arise from smooth muscle cells of the uterus. Clinically, they are found in 5-77% of women of reproductive age. The prevalence rate varies considerably in the literature and a large number of fibroids do not cause symptoms. The lifetime risk of acquiring myomas is 70% for Caucasian women and ≥ 80% for African American women. MATERIALS/METHODS: The data of 265 patients undergoing surgery for symptomatic myomas by laparoscopy or laparotomy, performed in the gynaecological department of Hannover Medical School, Hannover, Germany, between 2009 and 2013, were retrospectively analysed in this retrospective design study. RESULTS: High pregnancy rates (up to 70%) and birth rates (up to 86%) after myomectomy, regardless of the surgical approach adopted, were found in the current study. The trend was that ≥ 3 myomas and those that were ≥ 6 cm in size were almost always removed by laparotomy in our clinic. It was possible to remove up to 42 myomas without having to perform a hysterectomy. A statistically significant negative correlation was observed in relation to the association between the size of the largest myoma extracted and the pregnancy rate (p = 0.02). A statistically significant correlation between the number of removed myomas and the pregnancy rate was observed for patients who wished to bear children (p = 0.010). Elevated complication rates (of up to 50%) were reported for more than three extracted myomas with a statistically significance (p = 0.0471). CONCLUSIONS: It is necessary to ensure sound preoperative selection of the surgical approach in order to achieve the most optimal results, especially for those patients who wished to bear children.

Introduction: Besides the typical complaints and symptoms, myomas can cause sterility, infertility and complications during pregnancy. Laparoscopic interventions reach their limits with regard to organ preservation and the simultaneous desire to have children in the removal of multiple and larger intramural myoma nodes. The aim of this study is to examine fertility status and pregnancy outcome after myoma removal by minilaparotomy (skin incision maximal 8 cm) in women with pronounced uterus myomatosus. Materials and Methods: This retrospective study makes use of the data from 160 patients with an average age of 34.6 years. Factors analysed include number, size and localisation of the myomas, complaints due to the myoma, pre- and postoperative gravidity, mode of delivery, and complications of birth. Results: Indications for organ-sparing myoma enucleation were the desire to have children (72.5â%), bleeding disorders (60â%) and pressure discomfort (36.5â%). On average 4.95 (SD ± 0.41), maximally 46 myomas were removed. The largest myoma had a diameter of 6.64 cm (SD ± 2.74). 82.5â% of the patients had transmural myomas, in 17.5â% the uterine cavity was inadvertently opened. On average the operating time was 163 minutes (SD ± 45.47), the blood loss 1.59 g/dL (SD ± 0.955). 60.3â% of the patients with the desire to have children became pregnant postoperatively. 75.3â% of the pregnancies were on average carried through to the 38th week (28.4â% vaginal deliveries, 71.6â% Caesarean sections). In the postoperative period there was one case of uterine rupture in the vicinity of a previous scar. Discussion: By means of the microsurgical "mini-laparotomy" even extensive myomatous uterine changes can, in the majority of cases, be operated in an organ-sparing manner with retention of the ability to conceive and to carry a pregnancy through to maturity of the infant. The risk for a postoperative uterine rupture in a subsequent pregnancy and during delivery is minimal.
