This study was undertaken to evaluate the clinical usefulness of operative laparoscopy in treatment of benign ovarian cysts. A retrospective study was carried on 468 operative laparoscopy cases performed from September 1995 to September 1998 at Yonsei University College of Medicine, Department of Obstetrics and Gynecology. Patient characteristics, specimen pathology, perioperative morbidity, and perioperative complications were reviewed. The percentage of operative laparoscopy increased steadily from 20.7% in 1996, 33.9% in 1997, to 49.7% in 1998. The mean age of patients was 33.66.5 (mean +/- SD) years and the mean hospital stay was less than 2 days. Types of surgery performed were cystectomy (n = 234), salpingo-oophorectomy (n = 126), oophorectomy (n = 63), and fulguration (n = 45), in decreasing order. Depending on the pathology of the ovarian cyst, the mean operation time was in the range of 80 to 110 minutes. Perioperative complications included 5 cases of subcutaneous emphysema, 10 cases of abdominal wall hematoma, 7 cases of trocar site bleeding, 3 cases of bowel injury, and 1 case of bladder injury. In conclusion, operative laparoscopy in treating benign ovarian cysts provides advantages such as less need to perform laparotomy, smaller skin incision, less perioperative discomfort, minimal tissue handling and trauma, and shorter hospital stay. Nevertheless, the risk of unrecognized ovarian malignancy cannot be absolutely excluded, therefore careful patient selection is mandated.

Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

With the advent of B-mode transvaginal sonography, new opportunities are presented to better define ovarian lesions. Since its development in 1966, the transvaginal ultrasound continues to be an essential component in the diagnostic work-up of adnexal masses. This study reviewed the histopathological diagnoses of 387 patients who underwent surgery for removal of a benign ovarian cyst at our institution and compared it with the results of the patient's pre-operative ultrasound examinations done at the ultrasound section. After statistical analysis, this study showed that the B-mode transvaginal ultrasound is accurate in diagnosing the majority of benign ovarian cysts. Although it is more sensitive and specific for some types of benign ovarian cysts over others, it continues to be an important tool in the initial work-up of an ovarian cyst.

The medical records of twenty-one patients with suprascapular nerve palsy were reviewed retrospectively. Nine patients had isolated suprascapular nerve lesions and twelve patients accompanied axillary nerve lesions. In trauma cases, combined nerve lesions were common and severe. In three cases isolated suprascapular nerve lesions were noted spontaneously. Isolated infraspinatus muscle lesions were noted in four cases which were due to compressions of suprascapular nerves at the spinoglenoid notch, and in one case from ganglionic cyst was diagnosed by ultrasonography. At initial examination, three patients showed complete and eighteen patients showed incomplete lesion. Eight patients with incomplete lesion and one patient with complete lesion were followed up. Seven patients with incomplete lesion showed regeneration between 1-7 months after injury. Therefore electrodiagnostic study is necessary to evaluate severity and level of nerve lesion and regeneration.

Ultrasound guided percutaneous interventional therapy has been widely used in clinic. Aiming at the problem of soft tissue deformation caused by probe contact force in robot-assisted ultrasound-guided therapy, a real-time non-reference ultrasound image evaluation method considering soft tissue deformation is proposed. On the basis of ultrasound image brightness and sharpness, a multi-dimensional ultrasound image evaluation index was designed, which incorporated the aggregation characteristics of the organization. In order to verify the effectiveness of the proposed method, ultrasound images of four different models were collected for experiments, including prostate phantom, phantom with cyst, pig liver tissue, and pig liver tissue with cyst. In addition, the correlation between subjective and objective evaluations was analyzed based on Spearman's rank correlation coefficient. Experimental results showed that the average evaluation time of a single image was 68.8 milliseconds. The evaluation time could satisfy real-time applications. The proposed method realizes the effective evaluation of real-time ultrasound image quality in robot-assisted therapy, and has good consistency with the evaluation of supervisors.

Fetal abnormalities in central nervous system are now recognized more often with the increasing use of high-resolution prenatal sonography. Arachnoid cysts, because of their compression of adjacent brain tissue, may require neurosurgical intervention but otherwise they have a good long- term prognosis. The differential diagnosis of intracranial lesions is important to allow accurate counselling and also to optimize neonatal management. We report the two cases of fetal arachnoid cyst diagnosed with prenatal ultrasonography

With the development of fetal ultrasonography, detection of fetal ovarian cysts has been increased. Although ovarian cyst formation during the perinatal period is a self limiting process, there is still considerable controversy regarding the best treatment of the fetal ovarian cyst. The purpose of this study is to evaluate the natural history of fetal ovarian cysts and to analyze the result of treatment. From 1995 to 2004, 31 consecutive fetuses with ovarian cysts were followed by ultrasonography during the perinatal period. The fetal ovarian cyst was diagnosed by prenatal ultrasonography between 25weeks and 38 weeks and the mean size of the cysts was 5cm (ranged from 2 to 8cm). At birth, 3 cysts disappeared. In 2 cases, the diagnoses were changed to multicystic kidney disease and intestinal duplication. During following up of 26 cysts, 15 cysts have resolved completely. Seven cysts required oophorectomy because of cyst torsion (n=3), differentiation of tumorous condition (n=2), increased size of cyst (n=1), and large size (8cm) of cyst at birth (n=1). Fetal ovarian cyst should primarily be observed, and only in the limited cases, surgical treatment would be required for the risk of complications such as torsion and differentiation from benign to malignant pathology.

Ovarian cyst is found in 32% of necropsies in neonates, and can be visualized during gestation by ultrasonography. The clinical evolution of these cysts is variable, but in most cases the prognosis is favorable. Ovarian torsion, bleeding, rupture, and peritonitis have been described as complications. We report a newborn girl with torsion of ovarian cyst. A cystic mass measuring 41.9x31.9 mm on left side of abdomen was identified at 32 weeks of gestation by fetal ultrasonography. Surgery was performed after birth.
