1/260. A mullerian duct remnant myoma misdiagnosed as ovarian cancer in a woman with vaginal agenesis--a case report.

    Leiomyoma are very common in the normal uterus; however, they are rather rare in mullerian duct remnant. We report a case of mullerian duct remnant leiomyoma associated with vaginal agenesis. The mass had papillary growth with cystic-solid components by ultrasound. Ovarian cancer was suspected preoperatively. Finally, a fibroid with hyalinization and chondroid metaplasia was diagnosed histopathologically. To the best of our knowledge, this is the first case of mullerian duct remnant leiomyoma with degeneration, mimicking ovarian cancer by ultrasound. We provide the clinical details of this case and discuss a diagnostic pitfall.

2/260. Laparoscopic ultrasound guidance for laparoscopic resection of benign gastric tumors.

    Laparoscopic excision of gastric leiomyoma is technically feasible and safe, but it may fail to localize the exact placement of the lesion because of the lack of tactile sensitivity. The authors present two cases of small gastric leiomyomas that were resected by a totally laparoscopic approach, assisted with intraoperative laparoscopic ultrasonography because the lesions could not be palpated. A gastric wedge resection with tumor-free margins was performed with an endostapler device. Use of a harmonic scalpel to divide the gastroepiploic vessels facilitated the laparoscopic procedure.

3/260. Case report: intrahepatic portal-hepatic venous shunts associated with a huge pelvic leiomyoma.

    We present a case of portal-systemic encephalopathy due to intrahepatic multiple portal-hepatic venous shunts. A 71-year-old woman was admitted to our hospital because of recurrent episodes of disturbed consciousness. She showed no clinical signs of portal hypertension. liver function was normal, except for an indocyanine green retention rate of 34% at 15 min and blood ammonia level of 282 microg/dL. Portal venography revealed dilatation of the portal vein and multiple portal-hepatic venous shunts, and a liver biopsy specimen revealed almost normal liver. Further clinical examination revealed a huge pelvic tumour. At laparotomy, two dilated veins were seen to arise from the pelvic tumour with blood flow into the mesentery. The tumour was resected successfully and a histological diagnosis of leiomyoma was made. The blood ammonia concentration decreased to the normal range postoperatively. A follow-up portal venogram demonstrated decreased portal vein dilatation and minor portal-hepatic venous shunts, considered to be congenital in origin. It is concluded that hepatic encephalopathy was produced in this patient due to an excess portal blood flow from the huge pelvic leiomyoma via the mesentery, with portosystemic shunting through pre-existent (probably congenital) intrahepatic anastomoses.

4/260. Vision disturbances after operative hysteroscopy.

    Vision disturbance after transurethral resection of the prostate using glycine (1.5% aminoacetic acid) as the irrigating fluid is well known (TURP syndrome). Not so commonly seen or reported is transient blindness after operative hysteroscopy with glycine. It occurred in a 38-year-old woman who underwent hysteroscopic myomectomy and endometrial resection in which the distention medium was glycine. (J Am Assoc Gynecol Laparosc 6(2):213-215, 1999)

5/260. Pulmonary leiomyomatosis in women after hysterectomy for uterine myoma. Benign metastasizing leiomyoma?

    INTRODUCTION: Leiomyomas, which usually occur multilocular in uterus, can develop even if rarely in other organs with smooth muscle cells. The tumour is considered benign; 2 case reports supports the hypothesis that uterus myoma could metastasize, and in the metastasis sites grow invasively. methods: 2 female patients 44 y. and 29 y. old were admitted to our clinic for MPL. Due to increasing tumor size respectively dypnea, they were operated on. Multiple nodules of the left lung in one case, and a mediastinal tumour in the other were resected; resected tumour was histologically examined. RESULTS: In both cases it was a matter of well-differentiated leiomyosarcoma. The mediastinal tumour has already invade the N. phrenicus. Postoperatively there were no complications. patients discharged in well-doing state, medical control one year later revealed no new growth. CONCLUSION: Multiple pulmonary leiomyomas are rare, they occur in sexually mature women in coincidence with uterus myoma. Even though many authors assume that MPL is a lung metastasis of benign tumours, the pathogenesis is still hypothetical. Supporting this thesis is the hormone dependence of both the uterine and the pulmonary tumours; against it, is that extrapulmonary locations are too rarely observed. The still open pathogenetical question has no therapeutical consequence. Whenever technically possible, a radical, parenchyma-saving surgical therapy should be the first choice. Otherwise hormon-ablation is a good alternative.

6/260. Sonographic evaluation of a leiomyoma of the broad ligament of the uterus.

    Leiomyomas of the uterus generally have a characteristic ultrasound appearance. We present a case of leiomyoma of the broad ligament of the uterus. A 46-year-old woman who had previously undergone a hysterectomy had a pelvic mass with a whorled appearance and acoustic shadowing suggestive of a leiomyoma on sonography. Based on the sonographic appearance, a preoperative diagnosis of a leiomyoma was made despite the unusual location. Histologic examination of the excised mass revealed leiomyoma originating from the broad ligament.

7/260. Effectiveness of an inferior vena caval filter as a preventive measure against pulmonary thromboembolism after abdominal surgery.

    In three patients with a previous history of pulmonary thromboembolism, inferior vena caval filters were inserted before elective laparotomies to prevent a recurrent pulmonary thromboembolism. Two patients had colon cancer and underwent colectomies, while the other had myoma uteri, which might have been the cause of deep vein thrombosis, and thus a hysterectomy was performed. In spite of their poor risks, their postoperative courses were fairly good owing to perioperative management including anticoagulant therapy, and no recurrence has been observed since the operation in every case. A pulmonary thromboembolism is a fatal complication which follows deep vein thromboses. In patients with such a previous history, the risk is much higher after a laparotomy because of long-term bed rest, hypercoagulability, and so on. The mortality rate after a recurrence of pulmonary thromboembolism is reported to reach 30% without adequate therapy, whereas it is reduced to 8% with anticoagulant therapy, and to 0.8% with additional inferior vena caval filter placement. Considering the feasibility of insertion and the low incidence of complications, preoperative inferior vena caval filter placement is thus recommended for patients having a previous history of either pulmonary thromboembolism or deep vein thrombosis.

8/260. Torsion of a functional ovarian cyst in a premenopausal patient receiving tamoxifen.

    We report a case of torsion of an ovarian follicular cyst that developed during treatment with tamoxifen for breast cancer. A 40-year-old Japanese woman was admitted complaining of acute lower abdominal pain. Eight months earlier, she had undergone a partial mastectomy and local irradiation for ductal carcinoma of her left breast, estrogen receptor-positive stage I (T(1a) N(1b) M(0)). The administration of tamoxifen, 20 mg/day, and doxifluridine, 600 mg/day, were started immediately postoperatively. Pelvic examination after admission revealed the left ovarian cyst and enlarged uterus. Transvaginal ultrasonography and computed tomography revealed a multilocular cystic mass in the pelvic cavity. The pathological diagnosis of the tumor after total hysterectomy and bilateral salpingo-oophorectomy was a typical follicular cyst with torsion and uterine leiomyoma. This ovarian cyst was believed to have developed during tamoxifen administration.

9/260. Giant myoma and erythrocytosis syndrome.

    The objective of this study is to discuss the myomatous erythrocytosis syndrome in a patient with a giant subserous uterine myoma. She presented with plethora and an abdominal mass. After venesection of 4 units of blood, the preoperative haematocrit value of 53.3% and haemoglobin value of 17.5 g/dL had decreased to 48.6% and 16.8 g/dL levels, respectively. After the operative extraction of the giant subserous myoma with attached uterus weighing 14.2 kg, the haematocrit and the haemoglobin values had regressed to 40.3% and 14.3 g/dL levels, respectively. The findings indicated that the giant subserous myoma was the cause of the myomatous erythrocytosis syndrome in this patient.

10/260. Leiomyoma of the testis.

    testis leiomyoma is a very rare neoplasm. It is very difficult to perform an exact preoperative diagnosis; only histological examination can prove the presence of a leiomyoma. In our case radical orchidectomy was performed because of complete substitution of normal parenchyma, the extreme rarity at long-term follow-up of a reported benign intratesticular neoplasm, and the imperfect sensitivity of the extemporary histological examination.
