Filter by:rhThrombin is a serine protease from human.The study is to assess the Safety, Tolerability, Immunogenicity and efficacy of rhThrombin.
The prognosis of small liver cancer (≤5 cm) with stereotactic body radiotherapy (SBRT) is encouraging, the 1-year local control rate has been reported to be 95-100%, 3-year local control rate about 91%, and 3-year overall survival rate around 70%. So far, there is no randomized controlled study comparing SBRT and surgical treatment for early-stage liver cancer. It is hoped that this study will further compare the efficacy of SBRT and surgery for early stage liver cancer.
Pain after hepatectomy can interfere with the patients' recovery and may contribute to developing long term pain. Opioids, e.g. morphine, fentanyl, sufentanil, works well for postoperative analgesia, but have several side effects such as nausea, vomiting and itching which may be severe enough to affect patients' recovery. In some cases, opioids may cause constipation and urinary retention within the first 24 hours after surgery. Thus, several ultrasound-guided nerve block procedures have been applied to provide postoperative analgesia. Ultrasound-guided thoracic paravertebral block (TPVB) is one of the most used nerve block methods using for post-hepatectomy analgesia. However, in some cases, ultrasound-guided TPVB can cause pneumothorax, hemopneumothorax, and higher block level. The quadratus lumborum block (QLB) is a new developed nerve block which can provide a widespread analgesic effect from T7 to L1. Therefore, this study is to determine whether QLB or TPVB have a better pain control with fewer side effects and complications after laparoscopic and open hepatectomy. The adequate pain control will be assessed by their visual analogue score (VAS) and the postoperative quality of recovery scale (QoR-15, Chinese Version). Additionally, the side effect and complications profile of these two nerve block techniques will also be recorded and compared.
Lidocaine and ketamine both are being used for perioperative analgesia. Perioperative lidocaine infusion has been shown to reduce postoperative pain and opioid consumption. Perioperative low dose Ketamine has shown improved postoperative pain and reduced opioid usage. We therefore tested the hypothesis that the combination would provide better analgesia in the milieu of intrathecal morphine.
- Previous in vitro and in vivo studies detected the Hemopatch Sealing Hemostat® to be a new versatile, self-adhering hemostatic sealing pad consisting of a polyethylene glycol-coated collagen. - Initial study assessed that Hemopatch Sealing Hemostat® can be applied to seal almost any bleeding surface encountered during a range of procedures. The Authors shown that the device is eminently capable in both via laparotomy and laparoscopic approaches, and in patients with impaired coagulation or highly variable anatomies. They support the ease-of-use, application, and immediate hemostatic effect of the patch across a broad range of surgical settings and clinical applications, including solid organ, gastrointestinal, biliopancreatic, endocrine, cardiovascular, and urologic surgeries. - In a recent published case report the authors reported the feasibility in using Hemopatch Sealing Hemostat® for the management of a myocardial wound, performing the procedure on cardiopulmonary bypass, which meant the patient had to be heparinized. Despite these major risk factors for bleeding Hemopatch Sealing Hemostat® managed to contain bleeding and seal the wound without needing any suture. These initial results lead up to future randomized clinical trials with more extensive follow-up to assess which is the real contribution of Hemopatch Sealing Hemostat to reduce postoperative bleeding complications in cases where mechanical or energy-driven hemostasis is not possible or insufficient.
The surgical technique used in liver transplantation has undergone constant Evolution in an effort towards towards a safe, highly standardized procedure. Despite this, the initial step of the recipients' hepatectomy has not been in the focus of clinical research thus far. Due to usually advanced coagulopathy in liver transplantation recipients, this part of the operation still bares the risk of severe hemorrhage. This trial is designed to compare an electrothermic, bipolar vessel sealing device (LigaSureTM) and an ultrasound dissector (HARMONIC ACE®+7) to standard surgical techniques during the recipients' hepatectomy in liver transplantation. In a single center, prospective, randomized, controlled, parallel three armed, confirmatory, open trial, LigaSureTM and HARMONIC ACE®+7 will be compared to standard surgical techniques which, utilize titanium clips and conventional knot tying ligations during the recipients' hepatectomy in liver transplantation. Intraoperative total blood loss is the primary endpoint of the trial. Secondary endpoints include blood loss during the hepatectomy, the duration of both the hepatectomy and the entire surgical procedure, as well as blood transfusion requirements of the procedure. To generate reliable data, intraoperative blood loss will be recorded with respect to all rinse fluids during surgery, ascites and by weighing used swabs to generate reliable data. At 80% power and an alpha of 0.025 for both either of the experimental groups, twenty-three subjects will be analysed per protocol in each study arm in order to detect a clinically relevant reduction of intraoperative blood loss. The intention to treat analysis will include sixty-nine patients. The follow up period for each patient will be 90 days for safety reasons, whereas all clinical outcomes will be measured within the first ten postoperative days. This is the first prospective, randomized trial comparing two innovative, technical methods of vessel sealing and dissection against standard techniques for recipient hepatectomy. This will be done to detect a relevant reduction of intraoperative blood loss during liver transplantation.The results of the trial are expected to improve patients' outcome and safety after liver transplantation and to increase the general safety of this procedure.
The performance of hepatectomy for liver tumors using the thoraco-abdominal approach (TAA) versus the abdominal approach (AA) is still debated. The aim of the study is the analysis of the perioperative outcome of patients operated with or without the TAA for liver tumors.
Bupivacaine is a local anesthetic commonly used to manage postoperative pain. Liver resection patients typically have an epidural catheter placed preoperatively through which they receive a continuous infusion of bupivacaine and hydromorphone for up to 5 days postoperatively. The liver metabolizes bupivacaine, and produces proteins that bind with bupivacaine to take it out of circulation and thereby reduce its toxicity. Because a portion of the liver is being removed due to pre-existing liver disease, investigators hypothesize that liver resection patients have an impaired ability to clear bupivacaine from circulation that may increase their susceptibility to bupivacaine toxicity. To assess this, investigators will measure free and bound bupivacaine in liver resection patients postoperatively to determine whether bupivacaine reaches toxic levels. Investigators will also quantify binding protein levels to determine if these levels are reduced after surgery, which could contribute to the elevated bupivacaine levels in these patients. Finally, investigators will monitor patients for signs and symptoms associated with bupivacaine toxicity.
RAMEC is a phase II, multi-center, randomized trial with a safety test. There will be a safety test to establish the safety and tolerability of Neo-MASCT treatment and assess the immune response to the treatment.The randomized trial will assess DFS and immune response.
The investigators were aiming to evaluate whether dexamethasone administration accelerates the recovery from hepatectomy-related jaundice and decreases the rates of post-hepatectomy liver failure and its safety in the subjects who developed elevated serum total bilirubin.
