Parasitic myoma developing at the port site after laparoscopic myomectomy; a case report

Parasitic myomas occur especially after laparoscopic myomectomy and its incidence increases due to the use of morcellators. Parasitic myomas can rarely occur at the port entry site, being more commonly seen on the intestines, the omentum, the ureter, the bladder, and the diaphragm in different periods after surgery, the average duration being 24 months. In this article, we present the case of parasitic myoma developing secondary to the port site in a 45-year-old nulliparous woman after the use of laparoscopic myomectomy and morcellation 8 years ago. The patient presented with complaints of pelvic pain and a palpable mass in the left trocar incision line, and an appearance compatible with multiple myomas in the subcutaneous tissue of the left trocar incision line. Besides, myomas were also observed in the mesentery of the rectosigmoid colon and at the uterus in the present study. Numerous and large myomas were observed in the uterus, in the mesentery of the rectosigmoid colon, on the left pelvic peritoneum, and under the skin corresponding to the port entrance. The pathological examination of the myomas excised was reported as leiomyoma. In this article, the diagnosis, the treatment, the possible risk factors, and the complications of myomas were discussed in the light of the literature.

On dissection of the uterine wall during laparoscopic myomectomy

BACKGROUND: Laparoscopic myomectomy is becoming the leading method of surgical treatment of uterine fibroids while preserving reproductive and menstrual functions. Increasingly, ultrasound energy is used to dissect the myometrium. Meanwhile, the mode and direction of the ultrasound energy supply to minimize damage to the underlying tissues have not been specified. AIM: The aim of this study was to perform a comparative analysis of the myometrium and the fibroid pseudocapsule in the projection of the myoma nodule after dissection using ultrasound energy with different initial characteristics of the surgical instrument. MATERIALS AND METHODS: For comparison, we selected two instruments with a longitudinal ultrasound energy supply with an output frequency of 80 MHz ... 2.5 GHz and 47 kHz at intermittent operating mode of 5/10 sec and one torsion instrument with a transverse ultrasound energy supply with an output frequency of 36 kHz at intermittent operating mode of 3/30 sec. RESULTS: Our study has shown that the smallest zone of irreversible changes is formed when using ultrasound energy with an output frequency of 36 kHz at intermittent operating mode of 3/30 sec with its transverse feed at 90 degrees to the blade, and the largest zone of irreversible changes is formed when using ultrasound energy with an output frequency of 47 kHz at intermittent operating mode of 5/10 sec with its longitudinal feed. CONCLUSIONS: Morphometric studies with an analysis of the depth of necrotic and necrobiotic changes in the myometrial tissue showed that from the standpoint of reproductive surgery, it is preferable to use USE with an output frequency of 36 kHz at intermittent operating mode of 3/30 sec with its transverse feed.

Myomectomy or conservative management of uterine fibroids: effects on reproductive potential

AIM: The aim of this study was to analyze reproductive function, pregnancy and labor in women after laparoscopic myomectomy and in women with unoperated myoma. MATERIALS AND METHODS: The main group consisted of 60 patients aged 25-46 years with a scar on the uterus who had laparoscopic myomectomy. Inclusion criteria were full-term pregnancy, uterine scar after laparoscopic myomectomy for subserosal or intramural uterine myoma (3-10 cm), and myomatous nodules (one to three). The comparison group included 30 women aged 25-46 years who were not surgically treated. Inclusion criteria were full-term pregnancy, subserosal or intramural uterine myoma (3-10 cm), and myomatous nodules (one to three). All patients in the main group underwent laparoscopic myomectomy. In all cases, the myomatous nodule was removed intracapsularly, leaving the leiomyoma pseudocapsule, which, with a deep arrangement of the transmural myomatous nodules, avoided opening the uterine cavity; myomatous nodule morcellation being used. With a deep intramural arrangement of the leiomyoma, the myometrial defect was sutured layer by layer with the application of several rows of endosutures. RESULTS: Six months after myomectomy, the patients underwent MRI of their pelvic organs with contrast. In 95% of cases, the uterine scar had no anatomical insolvency. In assessing the anamnesis, gynecological diseases occurred two times more often in women in the main group: 22 (36.7%) patients resorted to the use of the in vitro fertilization method for pregnancy, while among the patients in the comparison group, there were only two (6.7%) of them (2 = 12.8; р 0.001). In the main group, moderate preeclampsia and gestational diabetes mellitus were twice as common. In the main group, all patients were delivered by caesarean section, of which 83.3% were planned and 16.7% were emergency. In the comparison group, 73.3% of patients were delivered through the natural birth canal and 26.7% by caesarean section (2 = 149, p 0.0001). The most unfavorable signs predisposing to obstetric complications and operative delivery were the presence of multiple nodules (OR = 5.96 (1.09-32.72), p 0.05), the location of the nodule or scar in the uterine bottom (OR = 2.52 (1.00-6.33), p 0.05), and their combination with IVF (OR = 9.09 (2.42-34.07), р 0.01). CONCLUSIONS: In 95% of women, the scar on the uterus after myomectomy was consistent, but all these pregnant women were delivered by cesarean section, mainly for combined indications. However, they carried out the pregnancy safely, with a good outcome for the fetus. In women with uterine myoma and its conservative management, there was a lower rate of aggravated gynecological history and obstetric complications, and 73.3% of them were delivered through the natural birth canal. Despite the increased risk of caesarean section, the presence of uterine fibroids, even of a large size (more than 4 cm), should not be considered as a contraindication to vaginal delivery.
