Case Reports[Laparoscopic repair of incarcerated diaphragmatic hernia as a late complication of laparoscopic right hepatectomy: a case report].
Incarcerated diaphragmatic hernia after laparoscopic right hepatectomy is very rare. An 81-year-old man underwent laparoscopic right hepatectomy for giant hepatic hemangioma. Twenty months after the surgery, he began to complain of nausea and abdominal pain and was brought to our hospital. ⋯ After successfully reducing the prolapsed colon back to the abdominal cavity, the diaphragmatic hernia orifice was repaired. Incarcerated diaphragmatic hernia sometimes causes the fatal state. Clinicians must therefore consider such findings a late complication of laparoscopic hepatectomy.

Review Case ReportsLeptomeningeal carcinomatosis originating from advanced gastric cancer--a report of three cases and review of the literatures.
Leptomeningeal carcinomatosis (LMC) is a rare complication of gastric cancer. Case 1. A 57-year-old female was diagnosed with gastric cancer and underwent distal gastrectomy with D2 lymph node dissection. Two years later, the patient suffered from para-aortic lymph node metastases and provided chemotherapy. During the chemotherapy, the patient emergently visited our hospital with chief complaints of a severe headache and dizziness. The above symptoms promptly abated by meningeal drainage, with a high value of the cerebrospinal fluid (CSF) pressure. Despite the administration of subsequent chemotherapy, the patient's clinical state rapidly worsened, including gradual progression of both blindness and hearing loss. Case 2. A 42-year-old male was diagnosed with Stage IV gastric cancer due to both distant lymph node metastases and an ascites. Chemotherapy with S-1 plus docetaxel was initiated. Upon finishing the fifth course of treatment, the patient complained of a severe headache. The magnetic resonance imaging (MRI) findings were suggestive of LMC. Under suspicion of carcinomatous meningitis, the patient underwent both cerebrospinal drainage with a high pressure value of 180 mmH2O and a cytological examination with a diagnosis of Class V. Immediately following the cerebrospinal drainage, the patient's symptoms promptly diminished. Case 3. A 66-year-old female was diagnosed with gastric cancer and underwent total gastrectomy with D2 dissection. About a year later, the patient suffered from the peritoneal dissemination, and provided serial chemotherapy regimens for 13 months. Thereafter the patient suffered from mildly stiff shoulders followed by serial severe headaches, and meningeal drainage was performed. The CSF showed pleocytosis and the presence of neoplastic cells, leading a diagnosis of LMC. After the placement of an Ommaya reservoir, the intrathecal chemotherapy was performed. Within two weeks of treatment, the patient's condition improved significantly, and the cell counts in the CSF obtained from the Ommaya reservoir remained low for six months after the first diagnosis of LMC. ⋯ Although gastric LMC-affected patients often exhibit a fatal clinical course, the administration of intrathecal chemotherapy may improve survival. Systemic chemotherapy may be also administered in a limited number of patients with a superior performance status. At present, each case requires the individual making treatment decisions. Further accumulation of clinical cases and improving the overall understanding of the pathogenesis of this disease is needed in order to advance in the treatment of gastric LMC.

Comparative StudyEffectiveness of fenofibrate in comparison to bezafibrate for patients with asymptomatic primary biliary cirrhosis.
Ursodeoxycholic acid (UDCA) is currently the only available pharmacological treatment for asymptomatic primary biliary cirrhosis (aPBC). Fibrates may be useful for treating aPBC patients who exhibit incomplete responses to UDCA. The mechanism of action of such fibrates involves the regulation of the expression of various kinds of lipids and proteins through the activation of peroxisome proliferator-activated receptor-alpha (PPAR-alpha ), which increases the phospholipid output into the bile and reduces the cytotoxicity of hydrophobic bile acids. Among these fibrates, the binding activity of fenofibrate to PPAR-alpha is stronger than that of bezafibrate. Because the majority of PBC patients exhibit a slow progression of their disease, and since the administration of UDCA plus fibrate may further delay the liver deterioration, cardiovascular risk factors, such as dyslipidemia may thus have a bigger impact on the long-term survival of PBC patients. The aim of this study was to evaluate the effects of fenofibrate in patients with aPBC who are refractory to UDCA and to simultaneously compare the effectiveness of fenofibrate with that of bezafibrate. ⋯ Combination therapies with fenofibrate plus UDCA and bezafibrate plus UDCA induce significant biochemical improvements in patients with aPBC. However, the ability of fenofibrate to reduce the LDL and uric acid levels in aPBC patients is superior to that of bezafibrate. As a result, the use of fenofibrate might translate into a decreased risk of developing cardiovascular events and renal failure in patients with aPBC.

Significance of stroke volume variation during hepatic resection under infrahepatic inferior vena cava and portal triad clamping.
Stroke volume variation (SVV), which is measured by analyzing arterial blood pressure waveform characteristics, is a simple and sensitive indicator of fluid responsiveness. The current retrospective study was to investigate SVV and central venous pressure (CVP) during hepatic resection under clamping of both the infrahepatic inferior vena cava (IVC) and the portal triad. ⋯ SVV is a useful indicator of intraoperative blood loss without the monitoring of CVP during hepatic resection under clamping of both the infrahepatic IVC and the portal triad.
