Previously we have investigated the cerulein-induced acute pancreatitis and provided data on its micro-rheological impact in the rat. We hypothesized that non-steroid anti-inflammatory agent flunixin, the xanthine-derivate pentoxifylline and the low molecular weight heparin enoxaparin may have various beneficial effects improving microcirculatory and rheological parameters. In female rats, under general anesthesia, 10 g/kg cerulein s.c. was administered and 2 hours afterwards microcirculation was tested by laser Doppler flowmetry on the tongue and after performing laparotomy on the small intestine, liver and pancreas prior to terminal blood sampling. From blood samples hematological parameters, blood pH, lactate concentration, erythrocyte deformability, osmoscan parameters and erythrocyte aggregation were tested. Compared to normal control in acute pancreatitis group we found severe deterioration in tissue microcirculation together with impaired erythrocyte deformability and enhanced aggregation, accompanied by acidic pH and increasing lactate concentration. Improvement was found when using flunixin (s.c.), pentoxifylline (i.p.) or enoxaparin (s.c.). These drugs could partly improve the blood flux on the surface of the investigated organs, and the flunixin had the most expressed improving effects on micro-rheological parameters. Surprisingly, the improving effect of pentoxifylline on micro-rheological parameters was not obvious (red blood cell deformability did not improved better than in the other treated groups), however, microcirculatory parameters improved.

Background: We compared retrospectively the results of the patients who underwent hemihepatectomy through anterior approach (AHH) with those undergoing conventional hemihepatectomy (HH). Patients and Methods: In 119 patients hemihepatectomy was done, 52 of them were anterior approaches. We used this technique if the tumor size was large or if the tumor seemed to be fragile, and thus a liver mobilization would be very dangerous. We started the operation with dissecting parenchyma from the anterior surface toward hilus without preparation of the hilus. Resection of the liver was performed with the help of CUSA dissector. Results: No patient died following AHH. Two re-operations were performed in the HH group, and 2 patients died. The operation time was not significantly different in both groups. The need for blood transfusion was much less during AHH. The average nursing days were also similar in both groups. However, in those cases in which the operations were performed because of liver malignancies, there were no differences in the survival rate after 32-month follow-up between both groups. Conclusions: AHH can be performed safely. The blood consumption during AHH is significantly lower than during HH. The median survival rate was similar in both groups. Our team suggest the anterior approach for liver resection in those cases when the hilar structures and the hepatic veins cannot be isolated easily.

Beneficial effect of triclosan against Gram positive bacteria could not be confirmed in our study due to the relatively low number of patients with SSI. Furthermore, triclosan did not influence the incidence of SSI due to Gram negative bacteria. SSI rate decreased by 50% compared to our previous study, however, it was regardless of the use of coated or uncoated PDS loop. Finally, operative factors were more important than patient's risk factors in terms of incidence of SSI. In case SSI developed, delayed discharge from hospital as well as special wound care significantly increased overall cost of treatment.

Female patients suffering from severe biliary acute pancreatitis have higher morbidity and mortality rate. Therefore an elective cholecystectomy is suggested in old female patients with serious co-morbidity and gallstones, before any complications.
