    Objectives. Caffeic acid phenethyl ester (CAPE) has been subjected to considerable investigations that have revealed its antioxidant and anti-inflammatory activities in different conditions. But there is not a previous investigation about its effect on cholestatic liver injury. The aim of this study was to investigate the effect of CAPE in rat liver against cholestatic liver injury induced by bile duct ligation. Methods. Swiss-albino rats were recruited in the study as follows; Group 1 rats subjected to simple laparotomy known as the sham group; Group 2 rats subjected to bile duct ligation (BDL); Group 3 bile duct ligated rats treated with CAPE. The third group received CAPE (10 mu mol/kg) intraperitoneally daily throughout 14 d. Results. Data showed a decrease in gamma glutamyl transferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase levels (ALT) of the CAPE treated rats, compared with BDL group (P < 0.001, P < 0.01, and P < 0.02, respectively). In the CAPE treated rats, tissue levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were significantly lower than that of the BDL group (P < 0.001). The levels of glutathione (GSH) in CAPE treated rats were significantly higher than that of BDL group (P < 0.001). In CAPE treated group, the levels of interleukin-1alpha (IL-1 alpha) and interleukin-6 (IL-6) were significantly lower than that of BDL group (P < 0.03, P < 0.02, respectively). Administration of CAPE in the rats with biliary obstruction resulted in inhibition of necro-inflammation. Conclusion. These results suggest that treatment of CAPE maintains antioxidant defenses, reduces oxidative liver injury, cytokine damage, and necro-inflammation in bile duct ligated rats. Thus, CAPE seems to be a promising agent for the attenuation of cholestatic liver injury. (C) 2010 Elsevier Inc. All rights reserved.

    Resection and primary anastomosis with or without modified blow-hole colostomy for sigmoid volvulus
    (W J G Press, 2008) Coban, Sacid; Yilmaz, Mehmet; Terzi, Alpaslan; Yidiz, Fahrettin; Ozgor, Dincer; Ara, Cengiz; Yologlu, Saim
    AIM: To evaluate the efficacy of resection and primary anastomosis (RPA) and RPA with modified blow-hole colostomy for sigmoid volvulus. METHODS: From March 2000 to September 2007, 77 patients with acute sigmoid volvulus were treated. A total of 47 patients underwent RPA or RPA with modified blow-hole colostomy. Twenty-five patients received RPA (Group A), and the remaining 22 patients had RPA with modified blow-hole colostomy (Group 13). The clinical course and postoperative complications of the two groups were compared. RESULTS: The mean hospital stay, wound infection and mortality did not differ significantly between the groups. Superficial wound infection rate was higher in group A (32% vs 9.1%). Anastomotic leakage was observed only in group A, with a rate of 6.3%. The difference was numerically impressive but was statistically not significant. CONCLUSION: RPA with modified blow-hole colostomy provides satisfactory results. It is easy to perform and may become a method of choice in patients with sigmoid volvulus. Further studies are required to further establish its role in the treatment of sigmoid volvulus.

    Small bowel perforation after drawing a blood sample in the femoral artery: a case report
    (Turkish Assoc Trauma Emergency Surgery, 2010) Ara, Cengiz; Coban, Sacid; Isik, Burak; Ozcan, Canan Ceran; Yilmaz, Sezai
    Small bowel perforation is a rare complication of femoral artery access in cases of femoral hernia. A 48-year-old woman was admitted to the intensive care unit due to pulmonary insufficiency. After a routine femoral arterial blood gas analysis, severe abdominal pain and nausea began. She underwent emergency laparotomy due to acute abdomen. Laparotomy revealed small bowel perforation. Segmental resection and end-to-end anastomosis were performed. The femoral canal was closed using plaque mesh. Special attention is needed during femoral artery access to avoid accidental small bowel perforation. As seen in this case, a careful examination should be done in cases of femoral hernia.
