Concepts in "fast-track" surgery, which provide optimal perioperative care, have been proven to significantly reduce complication rates and decrease hospital stay. This study explores whether fast-track concepts can also be safely applied and improve the outcomes of major pancreatic resections. Perioperative data from 255 consecutive patients, who underwent(More)
AIM To evaluate changes in the fatty acid composition of erythrocyte membrane phospholipids during severe and mild acute pancreatitis (AP) of alcoholic and nonalcoholic etiology. METHODS All consecutive patients with a diagnosis of AP and onset of the disease within the last 72 h admitted to the Hospital of Lithuanian University of Health Sciences between(More)
BACKGROUND The character of ablation processes with high-frequency electrical current is similar in most biological tissues; however, quantitative characteristics are very different. Consequently, mathematical models of the process have a lot of specific aspects. In this study, we developed mathematical model of radiofrequency ablation in liver tissues with(More)
Finite element model of radiofrequency ablation (RFA) with cooled-tip probe in liver has been developed by employing COMSOL Multiphysics software. It describes coupled electric, thermal and sodium chloride solution infiltration flow phenomena taking place during ablation processes. Features of hydraulic capacity, saturation of the tissue by infiltration,(More)
Heme oxygenase-1 (HO-1) is believed to represent a key enzyme for the protection of cells against "stress." Its overexpression in different types of human cancers supports the notion that HO-1 provides a growth advantage and contributes to cellular resistance against chemotherapy and radiotherapy. Given the poor survival rates of patients with pancreatic(More)
BACKGROUND Non-pancreatic periampullary carcinoma such as ampullary carcinoma (AmpCA), distal cholangiocellular carcinoma (CholCA) and duodenal carcinoma (DuoCA) have a better prognosis than pancreatic head adenocarcinoma (PanCA). This study describes the outcome and parameters, which predict survival of non-pancreatic periampullary carcinoma after(More)
The pathogenesis of pain in chronic pancreatitis remains an enigma. The cause of pain is almost certainly multifactorial and may vary at different stages of the disease process. These factors may include the release of excessive oxygen-derived free radicals, tissue hypoxia and acidosis, inflammatory infiltration with influx of pain transmittent substances(More)
AIM To study secretion patterns of pro- and anti-inflammatory cytokines, and activation of various cellular subsets of leukocytes in peripheral blood. METHODS We have conducted a prospective observational study. One hundred and eight patients with a diagnosis of acute pancreatitis and onset of the disease within last 72 h were included in this study. The(More)
OBJECTIVE Several tools have been developed for severity stratification in acute pancreatitis (AP). They include single biochemical markers and complex scoring systems, all of which aim at an early detection of severe AP to optimize monitoring and treatment of these patients. The aim of this study was to reassess and compare the value of some known and(More)
SUMMARY The role of postoperative supplementary enteral nutrition after gastrointestinal surgery is controversial. Therefore, a randomized clinical trial with attempts to address the question of plenitude of routine application of postoperative enteral feeding on rate of postoperative complications following pancreatoduodenectomy was performed.
