The majority of fibroids are asymptomatic and do not require any intervention or other exploratory measures. However, in some cases fibroids are symptomatic, their treatment should aim to improve symptoms and quality of life. Objectives: Describe the epidemiological-clinical aspects of uterine fibroids in the gynecology and obstetrics department of the reference health center of commune VI of the Bamako district. Methodology: This was a retrospective descriptive study carried out over a period of one year. It concerns all patients seen in consultation in the gynecology and obstetrics department of the reference health center of commune VI. Results: during the study period, the uterine fibroid frequency was 1.80%. During this same period, fibroids represented 5.59% of gyneco-obstetric pathologies operated on in the department. The 30 - 45 year old age group was the most represented with a frequency of 75.63%. The average age was 36.87 years ± 6.2 years with extremes of 25 and 63 years. Married women were the most represented 97.48%. The vast majority of our patients 95.8% were not postmenopausal. The multigravidas were the most represented, i.e. 37.50% with a large part of the pauciparous 41.29%. In our patients, 96.64% had a clinical symptom on their fibroid with the main reason for consultation being the sensation of a pelvic mass in 97.48%. We recorded three cases of infertility as associated factors. Ultrasound was performed in all patients. The location of the myxomatous nuclei was subserosal in the majority in 42.86% and with multiple nodules in 84.85% of cases. The main indication for myomectomy was the failure of medical treatment in 86.49% of cases. Surgical treatment was mainly a myomectomy 93.30%, a hysterectomy was indicated in 6.70%. No cases of death were recorded. Conclusion: Uterine fibroid is a gynecological pathology that exists in our department;its frequency is estimated at 5.59%. For better management of fibroids, it is necessary to have a good knowledge of the factors favoring the occurrence of uterine fibroids, their growth and the symptoms to prevent the appearance of it or even at best to operate. This prevention must be a concern for public health because fibromatous pathology is frequent, costly and hampers quality of life.展开更多

Due to the difficulties caused by its enormous size, the usual surgical treatment is a simple total hysterectomy. The surgery may be performed by either laparoscopy or laparotomy. However, the case presents a 45-year-old woman who was diagnosed with a giant myoma of 23 cm. The patient is asymptomatic and does not accept the indication of a simple total hysterectomy because of her fear to lose her femininity and a feeling of mutilation and unfulfilled genesic desire. A personalized procedure was performed: myomectomy by laparotomy with subsequent uterine reconstruction. The case is described to focus the interest on giant uterine myomas, taking into account the limited availability of literature on the topic, and to highlight the reconstruction after myomectomy.展开更多

Existing procedures such as performing myomectomy before hysterectomy or performing retrograde hysterectomy remain suboptimal in expanding the operative field, especially in cases with a huge cervical myoma. In this report, we introduce a new procedure, the “HALF-CUTTING METHOD” which can be used to obtain an adequate surgical field during hysterectomy.展开更多

Every woman was administrated mifepristone 150 mg in the first two days and Misoprostol 1 000 μg on d 3.Results The complete abortion rate was 89. 13%. The average bleeding duration was 11. 89± 6. 87 d. The expulsion time of gestational cyst was affected by the size of myoma. The bleeding duration and the expulsion time of gestational cyst were affected by the size of myoma and gestational cyst. The location and the number of myoma had no effect on the bleeding duration and the recovery of menses.Conclusion Mifepristone and Misoprostol could be safely and effectively used in the termination of early pregnancy with myoma.展开更多

文摘Background：The relationship between intramural myomas and fertility remains unclear.The main debate rests on whether cavity-distorting intramural lnyomas （CDMs） adversely affect fertility more than non-CDMs.We aimed to compare the effects ofenucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility.Methods：We prospectively recruited 83 women undergoing myomectomy for unexplained infertility with intramural myomas between June 2008 and November 2012 and classified them into non-CDMs group （n =45） and CDMs group （n =38）.We then compared postoperative infertility rates,spontaneous pregnancy rates,pregnancy outcomes,live birth rates,and obstetric complications.For continuous variables,we calculated the mean ± standard deviation,median and interquartile range,and analyzed the data using Student＇s t-test and the Mann-Whitney U-test.For categorical variables,the Pearson＇s Chi-square test,the continuity correction test,and Fisher＇s exact test were used.Results：Patients＇ demographics and myoma characteristics were comparable between the two groups.The overall spontaneous pregnancy rate increased from 0% to 68.42% following myomectomy.The postoperative infertility rate was significantly higher in the non-CDMs group than that in the CDMs group （50.00% vs.23.53%,t =5.579,P =0.018）,whereas the postoperative spontaneous pregnancy rate was significantly lower in the non-CDMs group than that in the CDMs group （47.62% vs.70.59%,t 4.067,P =0.044）.Compared with the enucleation ofnon-CDM,the enucleation of CDM patients was a protective factor for the fertility restoration （risk ratio [RR] =3.717,95% confidence interval [CI]：1.284-10.753,P =0.015）,although postoperative fertility restoration declined with age （RR =1.141,95% CI：1.005-1.295,P =0.041）.Conclusions：Intramural myomas are associated with impaired fertility.Women experiencing unexplained infertility,and possessing intramural myomas,have a better chance of conception following myomectomy,and these benefits are more obvious for younger patients and patients with CDM.
