A case of transverse vaginal septum with modified Garcia technique / 대한산부인과학회지

The incidence of all transverse vaginal septum is 1:2,100 - 1:72,000. The transverse vaginal septum is a developmental defect of vagina which may be fused incompletely between the Mullerian duct component and the urogenital sinus component of vagina. Serious complications may be hematocolpos, hematometra and hematosalpinx. Simple surgical excision or simple incision have been developed to treat congenital transverse vaginal septa, but also caused common complications such as secondary tissue contracture. Garcia technique using eight vaginal mucosa flaps was developed to avoid common complication of secondary vaginal stenosis. Here, we present a case of contracted transverse vaginal septum who has been performed a simple incision 13 years ago, successfully performed the modified Garcia technique without serious postoperative complication.

A case of focal uterine cystic adenomyoma / 대한산부인과학회잡지

The clinical and pathological features of an apparently unique case of an adenomyoitc cyst of the uterus are reported. The cyst was located within the myometrium of a 30-year-old woman suffering from vaginal bleeding for 6 months. Saline infusion sonohysterography revealed uterine cyst. After excision of the cyst, patient's symptoms improved. On histological examination, the cyst most closely resembled an adenomyotic cyst.

Comparative Results of Laparoscopically Assisted Vaginal Hysterectomy and Vaginal Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: To compare the outcomes of a method of assigning patients to a vaginal or laparoscopically assisted vaginal approach to hysterectomy. METHOD: Hysterectomy is the most common gynecologic operation. A clinical evaluation was attempted to analyze 100 cases of LAVH which was performed at St. Paul hospital from May 1997 to March 2000, and to compare them with 100 cases of vaginal hysterectomy at the same hospital. we used simple electrosurgical technique without using the disposable staples and other instruments. RESULTS: The mean age of the patients for LAVH was 46.18 years and that of VTH was 50.23 years. The most common indication for LAVH and VTH was Myoma uteri. The mean Hb change in LAVH was 2.15 and the Hb change of VTH was 2.17. The mean operative time of LAVH was 142.96 minutes and that of VTH was 77.06 minutes. The mean weight of uterus for LAVH was 221g and the mean weight of VTH was 182 g. The total percentage of urinary tract injury for LAVH was 3 % and that for VTH was 2 %. CONCLUSION: VTH, if possible, must be considered as a primary choice since it is were efficient than LAVH in cost, cosmetic aspects and complications. Further LAVH may be replaced with a laparotomy for hysterectomy in case of an insufficient operational experience, a previous abdominal operation hystory and the incapability of being indicated for VTH.

Expression of alpha-smooth muscle actin and collagenIV in villous stroma of placental terminal villi and congestion fetal capillary in growth restricted pregnancies with severe preeclampsia / 대한산부인과학회잡지

OBJECTIVE: Preeclampsia is the major cause of prenatal mortality and morbidity. The functional disorder of uteroplacental insufficiecy is caused by the impaired uteroplacental blood flow and diffusion barrier in the villi. Functional disorders like placental circulating disorders results in morphological changes of terminal. villi as functional unit of placenta. We studied to investigate the differences in villous stoma of placental terminal villi and fetal capillary between growth restricted pregnancies with severe preeclampsia and normal preterm pregnancies. METHOD: Terminal villi was examined using light microscopy and by immunohistochemical localization of matrix molecule (alpha-smooth muscle actin and collagenIV) and the immunoreactivity of alpha-smooth muscle actin and collagenIV were evaluated in 17 cases of severe preeclampsia with intrauterine growth restriction as a study group and in 17 cases of gestational age matched normotensive preterm pregnancies as a control group. Fetal capillary congestion in terminal villi was also evaluated by Hematoxylin-Eosin staining. The patterns of immunohistochemical staining were all determinated in a visual qualitative manner (0-25%: -, 25-50%: +, 50-75%: ++, 75-100%: +++) by one pathologist. Congestion was considered to be present in a failed where the majority (>90%) of the capillaries demonstrated densely packed erythrocyte. RESULT: Expression of alpha-smooth muscle actin in the terminal villous stroma was significantly increased in study group compared with control group (P=0.0001). Expression of collagen IV in the terminal villous stroma was significantly increased in study group compared with control group (P=0.0001). Fetal capillary congestion was also significantly increased in study group compared with control group (P=0.049). CONCLUSION: The result suggests that there be the structural or biochemical difference in the villous stroma between normotensive preterm pregnancies and severe preeclampsia with intrauterine growth restriction and that the extravascular contractile system might be in the villous stroma in the severe preeclampsia intrauterine growth restriction.

The Utility of Matrix Metalloproteinase-2 as a tumor marker in cervical cancer / 대한산부인과학회잡지

OBJECTIVE: Degradation of the extracellular matrix and the basement membrane is believed to be associated with tumor invasion and metastasis. To evaluate the roles of Matrix metalloproteinase-2 (MMP-2) in cervical cancer and its utility as a potential diagnostic tumor biomarker, we investigated the expression of MMP-2 in cervical cancer tissue and sera. METHODS: Through the zymography of MMP-2 in cervical cancer tissues from 35 patients, we investigated the extent and distribution of MMP-2. Also, up-regulation of its gene expression was examined by reverse transcription-polymerase chain reaction (RT-PCR) analysis. Then, we attempted to investigate by ELISA serologic responses in the sera obtained from 35 cervical cancer patients, and examined its utility as diagnostic and prognostic tumor marker in cervical cancer by comparing it with conventional tumor markers SCCA and CEA. RESULTS: In zymography, the active form of MMP-2 was detected in 66kDa. In cervical cancer the active form of MMP-2 is more strongly reacted with the substrates than those in normal tissues. Also, the mRNA of MMP-2 was more up-regulated in cervical cancer tissue than in normal one. MMP-2 was detected in the sera of cervical cancer patients, and its amount differed according to clinical situations. While it was not more effective than previous tumor markers SCCA and CEA in diagnosis, it was more useful in monitoring of the cancer. The effect was especially remarkable when it was combined with any other conventional tumor markers. CONCLUSIONS: The results suggest that the expressions of MMP-2 correlate with cervical cancer invasion and metastasis. Also, it may be useful in the monitoring of the cervical cancer lesion.

Effects of treatment sequence of cisplatin and paclitaxel (taxol) on cell cycle and cell death in NIHOVCAR-3 cell line / 대한산부인과학회잡지

The overt effects of the anticancer drugs such as cisplatin and taxol appear to be DNA modification and microtubule stabilization respectively. But the mechanism by which these drugs affect tumor cell cycle perturbation and their correlation to apoptosis and cytotoxicity are not well understood, especially in combined sequential treatment of cisplatin and paclitaxel (taxol). In this study, to elucidate the action mechanisms as a function of cell cycle changes and cytotoxicities and to determine the adequate treatment sequence of cisplatin and taxol to acquire more enhanced cytotoxic effects when they are combined, we evaluated the cell cycle perturbations and its correlation to cytotoxic effects, which is measured by the extents of apoptosis and the fractions of cellular debris and live cells after combination treatment of cisplatin and taxol changing their treatment sequences in NIHOVCAR-3 ovarian cancer cell line. Our results were as follows; (1) The accumulation in S phase inhibited the entrance of tumor cells to G2M phase when the cisplatin treatment was preceded to taxol in their combination. (2) The tumor cells were not accumulated in S phase but most of them entered to and accumulated in G2M phase and they were leading to cell death when the taxol treatment was preceded to cisplatin in their combination. (3) Apoptotic peaks in taxol pretreatment group were detected earlier and persisted longer than that of cisplatin pretreatment group. (4) The cytotoxicities represented by the decreased fractions of live cells and the increased fractions of cellular debris were higher in taxol pretreatment group than those of cisplatin pretreatment group. These results suggested that the taxol pretreatment is more effective in combination of cisplatin and taxol and the relative decrease in the cytotoxicity in cisplatin pretreatment group was considered to be derived from the inhibition of entrance of tumor cells to G2M and protected them from the action by taxol. From these results, we concluded that the taxol pretreatment will enhance the cytotoxic effects to tumor cells when cisplatin and taxol will be administered and it indicates that correlations between cell cycle perturbation, apoptosis and cell death have to be considered in the future combination treatment of other drugs and in the development of new treatment regimens.

Total Laparoscopic Hysterectomy: A review of 300 cases / 대한산부인과학회잡지

OBJECTIVE: We analyzed our experience with total laparoscopic hysterectomy to evaluate the clinical data such as operation time, blood loss, hospital stay, and complications. METHODS: A retrospective study was carried out in 300 women who underwent total laparoscopic hysterectomy (TLH). RESULTS: The most common indications for TLH were uterine myomas, chronic pelvic pain (severe endometriosis), cervical intraepithelial neoplasia. Mean operating time was 90 minutes (range 50-200 min) and hospital stay was 3 days (range 2 days-7 days). The most important factors for the surgery time were uterine size, assistant's skill, presence of adhesions (obliteration of the cul-de-sac due to severe endometriosis). Several techniques were used, including bipolar coagulation of the uterine vessels, and suture of the stump. A special uterine manipulator (RUMITM uterine manipulator with colpotomizer and pneumooccluder balloon) used in all procedures aided in anatomic definition and performing the circumferential colpotomy. We had three bladder injuries during operation which was diagnosed and immediately repaired laparoscopically. We had two cases of ureterovaginal fistula and one case of postoperative ileus. But there were no cases of death, thrombophlebitis neither other pulmonary complications. CONCLUSIONS:Total laparoscopic hysterectomy can be performed safely and effectively when the surgical team is sufficiently trained. And we believe that total laparoscopic hysterectomy offers benefits to the patients in the form of less post-operative pain, shorter time in hospital.

A Case of Nonimmune Hydrops Fetalis with neuroblastoma / 대한산부인과학회잡지

Hydrops fetalis is diagnosed when abnormal fluid collections are manifest in two or more fetal compartmnets including abdominal ascite, pleural effusion, percardial effusion, skin edema, polyhydroamniosis and placental edema. Although fetal hydrops was historically most commonly associated with Rh blood group isoimmunization, the availability of Rh immunoglobulin has increased the proportion of fetuses affected due to nonimmune etiologies. Neuroblastoma is a malignant tumor which originates in the autonomous nervous system. Congenital neuroblastoma is the most common solid malignant tumor of the neonatal period, incidence ranges 1:10,000 of all live births, retroperitoneal space being the most frequent localization. We have experienced a case of nonimmune hydrops fetalis with neuroblastoma at 32 weeks of gestation in 39 year old woman and reported that with brief review of related literatures.
