Two-staged hepato-pancreatoduodenectomy and interventional pancreaticojejunostomy

Two-staged pancreatoduodenectomy, including exteriorization of the pancreatic juice and second-look pancreaticojejunostomy, has been recommended for high-risk patients to avoid pancreatic leakage, which often causes intra-abdominal hemorrhage. We present a new technique of interventional pancreaticojejunostomy under both fluoroscopy and endoscopy without second-look laparotomy. A 77-year-old woman with local recurrence and liver metastasis from colon cancer underwent hepato-pancreatoduodenectomy with the external drainage of pancreatic juice via the pancreatic duct tube without pancreaticojejunostomy. Two months later, the jejunum was punctured with the insertion of a 5-F needle-knife into the pancreatic fistula during endoscopic observation of jejunal lumen, followed by the insertion of two 0.35-inch guidewires into the jejunum and the pancreatic fistula. Finally, a 10-Fr stenting tube was placed between the jejunum and the pancreatic fistula. No complications developed.     

Decreased plasma adiponectin concentrations in women with low-grade C-reactive protein elevation

OBJECTIVE: Inflammation has been suggested as a risk factor for the development of atherosclerosis, while some components of metabolic syndrome X have been related to inflammatory markers. We hypothesized that adipocyte secreting protein, adiponectin and leptin, for which have been demonstrated an association with metabolic syndrome X and coronary artery disease, may be associated with inflammatory markers in nondiabetic humans. DESIGN AND METHODS: We measured high-sensitivity C-reactive protein (hs-CRP), as an inflammatory marker, and adiponectin and leptin concentrations in 384 nondiabetic Japanese women (mean+/-s.e.m. age 53.6+/-0.8 Years, body mass index (BMI) 23.0+/-0.2 kg/m(2)) undergoing measurement of markers of metabolic syndrome X. RESULTS: The women who had a low-grade hs-CRP elevation (>2.0 mg/l) were significantly older and had higher BMI, body fat mass (BFM), total cholesterol (TC), triglyceride (TG), atherogenic index (AI=(TC-HDLC)/HDLC), where HDLC is high-density lipoproten-cholesterol), fasting blood glucose and leptin concentrations before and after adjustment for BMI or BFM, while lower HDLC and adiponectin concentrations before and after adjustment compared with women with normal CRP levels (<0.5 mg/l). BMI, BFM, TG, AI and leptin before and after adjustment were found to be correlated with hs-CRP levels, while HDLC and adiponectin before and after adjustment were inversely correlated (all P<0.0001). hs-CRP was independently associated with white blood cell count, blood urea nitrogen and AI and inversely with adiponectin/BFM in the stepwise regression analysis model. CONCLUSIONS: These data demonstrate a significant decrease in plasma adiponectin in low-grade chronic inflammation, and suggest that there is an important linkage between inflammation/adipose tIssue/atherosclerosis.     

Soluble Fas ligand and atherosclerosis in hypertensive patients

BACKGROUND : The Fas-Fas ligand (FasL) system is involved in apoptosis in many types of cells. Recently, the expression of FasL on endothelial cells was reported. FasL is cleaved by a metalloproteinase and released in serum as soluble FasL (sFasL). Vasoactive substances, including metalloproteinase, are modulated by endothelial dysfunction. Advanced atherosclerosis and impaired endothelial function are seen in hypertensive patients. The inflammatory response has an important role in the development of atherosclerosis, whereas C-reactive protein (CRP) is associated with the presence and severity of atherosclerosis. OBJECTIVE : To measure the intima-media thickness of the common carotid artery and evaluate the relationship between atherosclerosis and serum sFasL concentrations in hypertensive patients. PATIENTS AND MAIN OUTCOME MEASURES : Forty-seven patients with hypertension participated in the study. The intima-media thickness of the common carotid artery was evaluated by ultrasound imaging. Serum concentrations of sFasL were measured by enzyme-linked immunosorbent assay. RESULTS : Intima-media thickness correlated positively with age (r = 0.362, P = 0.012) and sFasL concentrations (r =0.332, P = 0.022), and negatively with creatinine clearance (r = -0.399, P = 0.0055). A general linear model analysis with atherosclerotic risk factors and sFasL revealed that age, sFasL, high-density lipoprotein-cholesterol and systolic blood pressure were significantly associated with intima-media thickness. Furthermore, we demonstrated that serum sFasL is directly associated with CRP concentration (r = 0.316, P = 0.030). CONCLUSIONS : These results indicated that serum sFasL concentration is associated with atherosclerosis and inflammatory disease, in patients with hypertension.
