Laparoscopy is a surgical procedure used both for diagnosis and for various treatments. A rare but sometimes fatal complication of laparoscopy is pulmonary embolism with CO2 resulting in pulmonary edema. During laparoscopic gynecological surgery in a 29-year-old woman who had previously undergone lower abdominal surgery, the end-tidal CO2 suddenly increased from 40mmHg to 85mmHg and then decreased to 13mmHg with hemodynamic deterioration. These events are characteristic of a CO2 embolism. When this occurred, CO2 insufflation was immediately stopped and the patient was resuscitated. The patient's condition gradually improved with aggressive treatment, but the clinical course was complicated by bilateral pulmonary edema. This case of pulmonary edema was soon resolved with supportive management. The formation of a CO2 embolism during laparoscopy must be suspected whenever there is a sudden change in the end-tidal CO2. In addition, the possibility of pulmonary edema should be considered when a CO2 embolism occurs.

Hepatic peribiliary cysts (HPCs) are characterized by cystic dilatations of the peribiliary glands located throughout the branches of the biliary systems. Specifically, they are mainly located along the hepatic hilum and major portal tracts. The natural history and prognosis of HPCs are uncertain. In fact, almost all HPCs have been discovered incidentally during radiological examination or autopsy, and they are considered to be clinically harmless. Recently, several cases of HPCs associated with obstructive jaundice or liver failure were reported in patients with pre-existing liver disease in several studies. However, until now there have been no reports of such a case in Korea. Herein, we report a case of HPCs that show a disease course with a poor prognosis. These HPCs developed in a 47-year-old man with progressive alcoholic liver cirrhosis.

Clear cell chondrosarcoma is a rare cartilaginous tumour of low-grade malignancy. Although it has a characteristic histological appearance, its radiological features and clinical presentation often mimic a benign lesion. Herein, we describe the case of a patient with a clear cell chondrosarcoma of the right proximal femur that had an atypical appearance of chronic avascular necrosis on initial plain radiographs, which made preoperative diagnosis a challenge. In addition, the tumour also had extensive areas of aneurysmal bone cyst-like changes, which is not only a rare histologic phenomenon in clear cell chondrosarcoma, but also a confounding factor in the interpretation of the radiologic findings.

Objective: To investigate the success rate and safety of percutaneous vasoseminal vesiculography with the disposable vasographic interventional therapy kit (VITK). METHODS: This study included ninety-six 19－65 (mean 43) years old male patients with infertility, hematospermia, seminal vesicle cyst, ejaculatory duct cyst, ejaculatory dysfunction, or vas deferens injury, with disease courses varying from 1 month to 7 years. With an open, multi-centered, single-group, self-controlled design and using the disposable VITK, we treated the patients by percutaneous vasoseminal vesiculography via injection of contrast medium into the vas deferens cavity under local anesthesia. RESULTS: Percutaneous vasoseminal vesiculography was successfully performed in 92 (97.87%) of the patients, which revealed abnormal seminal ducts in 51 cases (54.3%). Among the 28 infertile patients, 3 were found with bilateral and 5 with unilateral vas deferens obstruction. Vesiculitis was detected in 36 (81.8%) of the 44 hematospermia patients and bilateral vas deferens abnormality in 5 (38.5%) of the 13 patients with ejaculatory dysfunction. Transectional damage was observed in 2 patients with vas deferens injury induced by bilateral inguinal hernia repair. Three cases of seminal vesicle cyst and 4 cases of ejaculatory cyst were definitely diagnosed by vasoseminal vesiculography. CONCLUSIONS The disposable vasographic interventional therapy kit, with the advantages of simple operation and high safety, deserves a wide clinical application in vasoseminal vesiculography.
