A 70-year-old woman presented with extending varicose veins of her left lower extremity. She had a Seventeen years previously she suffered a stab wound in her left lower extremity. She had a thrill in her left groin and a pulsatile mass in her lower abdomen on the left side. Venography showed ‘to and fro’ sign in her popliteal vein. Arteriography and computed tomography (CT) scan revealed left popliteal arteriovenous fistula and dilated femoral artery and vein, in addition to a giant iliac venous aneurysm (9cm in diameter). The shunt ratio was calculated at 3.4. We separated the fistula using ringed ePTFE grafts. After the operation, her varicose veins remarkably diminished. CT scans showed that the iliac venous aneurysm diminished to 3.6cm with no internal thrombus at three weeks after the operation. Cases of traumatic arteriovenous fistula with venous aneurysm that occurred in parts other than the fistula are rare and there are only two cases in the international literature.

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) infectious endocarditis (IE) which was successfully treated with linezolid (LZD). The patient was a 44-year old woman. She was referred to our hospital because of fever of unknown origin. MRSA was detected from blood cultures and echocardiography revealed vegetation on the right coronary cusp of the aortic valve. She was diagnosed with MRSA endocarditis according to the Duke criteria, and was immediately give vancomycin (VCM) and isepamicin. Sixteen days after administration of VCM, she had a progressively increasing skin rash. It was considered a side effect of antibiotics and VCM was replaced with teicoplanin (TEIC). Eventually, LZD was given to her at 22 days after hospitalization because TEIC was not effective. LZD alleviated the fever and diminished the signs of vasculitis due to endocarditis within a week. LZD was continued for 4 weeks with cardiac failure medically controlled, and she underwent aortic valve replacement using a mechanical prosthetic valve. LZD was injected just before the operation and continued for 15 days postoperatively, followed by oral administration of levofloxacin. She was discharged 35 POD and no recurrence of the infection had been observed at 1 year after the surgery. LZD could be an alternative therapy for MRSA endocarditis, but further examinations are warranted to determine the most appropriate regimen.

Objective: The survival benefits of retroperitoneal lymphadenectomy (RLNA) for epithelial ovarian cancer (EOC) remain controversial because clinical behaviors differ among subtypes. The purpose of the present study was to clarify whether RLNA increases the survival rate of advanced high-grade serous carcinoma (HGSC). Methods: This was a retrospective cohort analysis of 3,227 patients with EOC treated between 1986 and 2017 at 14 institutions. Among them, 335 patients with stage IIB-IV HGSC who underwent optimal cytoreduction (residual tumor of <1 cm) were included. Patients were divided into the RLNA group (n=170) and non-RLNA group (n=165). All pathological slides were assessed based on a central pathological review. Oncologic outcomes were compared between the two groups in the original and weighted cohorts adjusted with the inverse probability of treatment weighting. Results: The median observation period was 49.8 (0.5–241.5) months. Overall, 219 (65%) out of 335 patients had recurrence or progression, while 146 (44%) died of the disease. In the original cohort, RLNA was a significant prognostic factor for longer progression-free survival (PFS) (hazard ratio [HR]=0.741; 95% confidence interval [CI]=0.558–0.985) and overall survival (OS) (HR=0.652; 95% CI=0.459–0.927). In the weighted cohort in which all variables were well balanced as standardized differences decreased, RLNA was also a significant prognostic factor for more favorable oncologic outcomes (PFS, adjusted HR=0.742; 95% CI=0.613–0.899) and OS, adjusted HR=0.620; 95% CI=0.488–0.787). Conclusion The present study demonstrated that RLNA for stage III-IV HGSC with no residual tumor after primary debulking surgery contributed to better oncologic outcomes.

Background: The glissonean pedicle approach was introduced by Couinaud and Takasaki in the early 1980s. The key of the glissonean pedicle approach is clamping the pedicle first, secondly confirming the territory, and finally dissecting the liver parenchyma. In this presentation, we introduced our recent refinements of glissonean pedicle approach for liver resection. “Approach to the glissonean pedicles at the hepatic hilus” Couinaud described three approaches to the hepatic hilus. 1) Intra-fascial access (Control method): The conventional dissection at the hilus or within the sheath is referred to as intrafascial access However, dissection performed under the hilar plate is dangerous and surgeons have to consider any variations of the hepatic artery and bile ducts. 2) Extra-fascial access (Glissonean pedicle approach): The glissonean pedicle is dissected from the liver parenchyma at the hepatic hilus before dissecting the liver parenchyma. This procedure prevents intrahepatic metastasis of HCC, which spreads along the portal vein and improves the overall survival after surgery. 3) Extra-fascial and transfissural access: If the main portal fissure or the left suprahepatic fissure is opened after dissecting the liver parenchyma, the surgeon can confirm the pedicles that arise from the hilar plate or the umbilical plate. “Operative techniques” 1) Preoperative 3D simulation of the precise anatomy of portal vein, hepatic artery and bile duct at hepatic hilus should be performed. 2) Right glissonean pedicle: The hilar plate is detached from the quadrate lobe. The assistant pulls the liver parenchyma cranially and the operator conversely pulls the hepatoduodenal ligament caudally. Mayo scissors are inserted along the liver parenchyma between the liver parenchyma and glissonean capsule (Fig.1). Then forceps are inserted in the same way and the right main pedicle is taped (Fig.2). The right anterior and posterior glissonean pedicles are taped as well. 3) Left glissonean pedicle: The hilar plate is detached from the liver parenchyma. Then, the Arantius duct is confirmed and the left pedicle is dissected along the left pedicle at the ventral side of the Arantius duct. “Pitfall of glissonean pedicle approach” The right pedicle should be dissected in the liver side as much as possible to prevent the injury of left hepatic duct. If possible, the right pedicle is recommended to be dissected at the level of the second branches separately (Fig.3). The right posterior hepatic duct sometimes branches from the left hepatic duct and the Arantius duct is confirmed and the left pedicle should be dissected along the left pedicle at the ventral side of the Arantius duct because the right posterior hepatic duct branches from the left hepatic duct at the dorsal side of Arantius’ duct. In addition, the intraoperative cholangiogram should be used in the case with the abnormal anatomy of bile duct. Conclusions: Any anatomical hepatectomy can be performed using “glissonean pedicle approach” which allows simple, safe and easy liver resection.
