View clinical trials related to Major Liver Resection.
Filter by:This will be a prospective, randomized, double blind trial enrolling patients who will undergo major liver resection. Patients will be randomized in a 1:1 ratio to receive either octreotide or placebo in the postoperative period. The patients will receive octreotide intravenously continuously for five days after operation. During this period the patients' health will be monitored by performing blood tests including complete metabolic profile, Complete Blood Count (CBC) with/diff., INR and PTT. The functioning of heart will also be monitored post-operatively by EKG. Up to 80 participants will be accrued over a 2 year period. Volumetric CT scans will be performed prior to hepatectomy, 1 week after hepatectomy and 3 months after hepatectomy to evaluate liver regeneration.
Surgery is in almost all cases the only potentially curative treatment option for patients with primary or secondary malignancies of the liver. However, in most cases oncological resections ("R0-resections") can only be achieved by performing major liver resections (4 or more liver segments), which is related to considerable postoperative complications such as systemic infections and postoperative liver insufficiency (postresectional liver failure (PRLF)). Despite optimized preoperative and postoperative strategies of care presently, up to 32-55% of patients display severs postoperative complications (Clavien score ≥ 3a) and 5% even suffer from a severe PRLF. Recent observations in murine disease models as well as human patients suggested that postoperative alterations of hemodynamics within the portal vein tract as well as postoperative modulations of the immune response facilitates the translocation of gut bacteria in the blood, leading to systemic infections and sepsis. Moreover it became apparent that inflammatory mediators, released by the gut microbiota might negatively affect postoperative liver regeneration. Rifaximin (Xifaxan®) is a novel and potent, semisynthetic antibiotic that efficiently acts against most enteric bacteria and significantly reduced liver inflammation and liver fibrosis in animal studies. Moreover, Rifaximin is very well tolerated, even in patients with liver insufficiency.
