Filter by:Commonly the pressure of about 14 mmHg is applied during laparoscopic liver resection (LLR) with moderate neuromuscular blockade. Lowering the pneumoperitoneum pressure combined with deep neuromuscular blockade may sustain optimal operating space with providing better short-term postoperative results. It has been proved in randomized controlled trials in colorectal or bariatric patients, however there is lack of similar data for laparoscopic liver resection. Doubts about lowering the pneumoperitoneum pressure too hasty are supported by apprehension of worse bleeding control during liver parenchyma transection and its impact on postoperative results. The aim of the trial is to assess the impact of standard (14 mmHg; arm 1) versus low (10 mmHg; arm 2) pneumoperitoneum pressure on intraoperative blood loss, what will be the primary outcome. As secondary endpoints following outcomes will be measured: quality of operating space, intraoperative adverse events, quality of recovery, postoperative renal function, 30-day postoperative complications rate, length of hospital stay. The investigators assume that lower pneumoperitoneum provides non-inferior blood loss control during laparoscopic liver resection with better postoperative results.
Patients with liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were allocated into three groups based on tumor size and number: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA. Evaluative parameters included the Numerical Rating Scale (NRS) scores, consumption of morphine, incidence of complications, and factors influencing perioperative pain.
To explore the objective effectiveness and safety of TACE combined with Lenvatinib in the treatment of advanced liver cancer. After successful down-stage, radical microwave ablation was further performed.
After the two consensus meetings on laparoscopic liver resection in Louisville (2008) and in Morioka (2014) minimally invasive approach for liver resection was finally widely established in liver surgery practice. Successively more countries follow laparoscopic liver pioneers and apply laparoscopic liver surgery for everyday practice. Primary aim of the study is to assess the evolution and diffusion of minimally invasive liver surgery in Poland. Secondly, it will allow to assess the actual short- and long-term results of laparoscopic liver resections and compare it to the international benchmark values. The National Polish Registry of Minimally Invasive Liver Surgery will include data about all cases of laparoscopic liver resections performed in Poland since the first case in 2010. All surgical departments, where laparoscopic liverresection is regularly performed, will be invited. Data of demography, previous medical history, preoperative assessment, intraoperative and postoperative period, histopathological findings and long-term follow-up will be included in the registry. This study will be the first national report about diffusion of minimally invasive surgery in Poland.
This study will comprise the first pilot clinical trial of 3D, ultrasound-based thermal ablation control using echo decorrelation imaging, directly testing the capability of this approach to ensure reliable tumor treatment. The purpose of this study is to determine the ability of ultrasound echo decorrelation to successfully predict complete ablation of human hepatocellular carcinoma, concomitant diseased liver, and metastatic liver cancer and to determine the potential of echo decorrelation imaging to provide effective real-time control of radiofrequency ablation (RFA) in liver tumors.
The objective of this study is to compare open and minimally invasive pancreatic and liver resection techniques and analyze the different outcome variables from the clinical standpoint. The plan is to investigate patient survival, length of stay, complication rates, operative time, transfusion rate, 30 and 90-day readmission rate, and hospital charges.
This will be a randomized study on the effects of hypothermic oxygenated machine perfusion in patients undergoing liver transplantations from donors after brain death with allocation of patients to either end-ischemic hypothermic oxygenated machine perfusion group (at least 2 hours of allograft perfusion at 12 degrees Celsius though hepatic artery and portal vein prior to implantation) or simple cold storage group in a 1:3 ratio. The primary outcome measure of the study will be model for early graft dysfunction (MEAF) score. A total number of 104 patients, including 26 in the hypothermic perfusion group and 78 in simple cold storage group will be included. Data on potential risk factors for worse allograft function and increased ischemia-reperfusion injury will be collected perioperatively. Circulating levels of proinflammatory cytokines (IL-2, IL-10, TNFα), nuclear damage (HMGB-1, 8-OHdG), serum activity of transaminases, gamma-glutamyl-transpeptidase, bilirubin concentration, and INR will be assessed in the perioperative period. Wedge allograft biopsies will be performed 90 minutes post-reperfusion to evaluate activation of innate immunity (TLR4), activation of endothelium (vWF, P-selectin), hepatocyte necrosis, hepatocyte apoptosis (TUNEL assay), ATP content, and oxidative damage (malondialdehyde content). Further, wedge biopsies will be performed at the end of simple cold storage and at the beginning and after two hours of perfusion to determine steatosis and ATP content. During the perfusion, perfusate samples will be periodically tested for lactate, sodium, and potassium concentration, CO2 partiall pressure, and flavin mononucleotide concentration. Patients will be closely monitored in the postoperative period for allograft function and secondary end-points: 2-year recipient and graft survival, 2-year incidence of biliary complications, and 90-day complication rate. Both groups will be compared with respect to the primary and secondary end-points, circulating levels of IL-2, IL-10, TNFα, HMGB-1, 8-OHdG, activity of transaminases and gamma-glutamyl-transpeptidase, and findings in post-reperfusion allograft biopsies. Further, changes of hepatic steatosis and hepatic ATP content during perfusion will be evaluated, and the results of perfusate analyses will be tested as predictors of allograft function in the post-transplant period.
Centralized biological collection of multicentric origin, retrospective and prospective of biological samples (tissues and fluids) taken within the framework of the diagnostic and therapeutic management of children and adolescents with liver tumor, and supported in the centers of French Society for Childhood Cancers (SFCE) with associated clinical database.
"Indocyanine Green (ICG) is a dye used as an indicator of hepatic function considering its capacity to be eliminated only by the bile. Thus, ICG tend to remain in liver tumors. The hypothesis of CAMVIC study is that the use of fluorescence imaging during laparoscopic hepatic surgery will allow to detect small subcapsular superficial lesions undetected by other diagnostic methods, which will improve the results of the oncologic treatment."
The purpose of this research is evaluate the results with laparoscopic ALPPS procedure in a single center. The validity, feasibility and limitations were assessed objectively through our clinical prospective study.The investigators expect laparoscopic ALPPS is safe, effective and feasible.
