Background: The incidence of hepatocellular cancer in complicated alcoholic and non-alcoholic fatty liver diseases is on the rise in western countries as well in our country. Vascular adhesion protein-1 (VAP-1) levels have been presented as new marker. In our study protocol, we assessed the value of this serum protein, as a newly postulant biomarker for hepatocellular cancer in patients with a history of alcoholic and non-alcoholic fatty liver diseases. Methods: Pre-operative serum samples from 55 patients with hepatocellular cancer with a history of alcoholic and non-alcoholic fatty liver diseases and patients with cirrhosis were assessed by a quantitative sandwich ELISA using anti-VAP-1 mAbs. This technique is used to determine the levels of soluble VAP-1 (sVAP-1) in the serum. Results: sVAP-1 levels were evaluated in patients with hepatocellular cancer and liver cirrhosis. There was a significant difference in mean VAP-1 levels between groups. Serum VAP-1 levels were found higher in patients with hepatocellular cancer. Conclusion: These findings indicate that the serum level of sVAP-1 might be a beneficial marker of disease activity in chronic liver diseases.
T-Tube Bridging for the Management of Biliary Tree Injuries
(int Scientific Literature, inc, 2012) Olmez, Aydemir; Hatipoglu, Sinan; Itik, Veyis; Kotan, Cetin
Background: Injuries of the biliary tree, which mainly occur as a complication of laparoscopic cholecystectomy, are a potentially life threatening cause of high morbidity and mortality. The reported frequency of biliary injuries after laparoscopic cholecystectomy is from 0.5-0.8%. Such injuries may sometimes become too complicated for surgical repair. Presented here is the case of a patient with a major bile duct injury for whom bile duct continuity was achieved using a T-tube. Case Report: A 53-year-old man, who developed bile duct injury following a laparoscopic cholecystectomy performed in another center for cholelithiasis, was referred to our clinic. A Roux-en-Y hepaticojejunostomy was performed in the early postoperative period. However, ensuing anastomotic leakage prompted undoing of the hepaticojejunostomy followed by placement of a T-tube by which bile duct continuity was achieved. Conclusions: For injuries with tissue loss requiring external drainage, T-tube bridging offers a feasible option in that it provides bile duct continuity with biliary flow into the duodenum, as well as achieving external drainage, thus alleviating the need for further definitive surgery.
