Bleeding in Laparoscopic Liver Surgery
Neuromuscular BlockadeIntraoperative Bleeding1 moreBlood loss during liver resection surgery affects patients morbidity, short and long-term mortality. Among non-surgical interventions to minimize intraoperative blood loss and perioperative blood products transfusion, maintaining conditions of low central venous pressure is considered as standard of care. In animals undergoing laparoscopic hepatectomy, reducing airway pressures represents a minimally invasive measure to reduce central venous pressure and therefore bleeding from the hepatic vein. Neuromuscular blocking agents are usually administered during anesthesia to facilitate endotracheal intubation and to improve surgical conditions: a deep level of neuromuscular blockade has already been shown to reduce peak airway pressures and plateau airway pressures in non-abdominal procedures. Such airway pressures reduction can potentially limit bleeding from hepatic veins during transection phase in liver surgery. The aim of the present study is to evaluate the impact of deep neuromuscular blockade on bleeding (as a consequence of reduced airway peak pressure and plateau pressure) in hepatic laparoscopic resections. Patients undergoing laparoscopic liver resection will be randomized to achieve, using intravenous Rocuronium, either a deep neuromuscular blockade (post-tetanic count = 0 and/or = 1 and train of four count = 0) or moderate neuromuscular blockade (train of four count ≥ 1 and/or post-tetanic count > 5) during surgery. Neuromuscular blockade measurements will be performed every 15 minutes. The primary endpoint is to assess the total blood loss at the end of the resection phase.
Resection And Partial Liver Segmental Transplantation With Delayed Total Hepatectomy
Liver MetastasesRAPID is an auxiliary liver transplantation where a small liver partial graft (namely left lateral segments from living or cadaveric donors) is implanted orthotopically after a left hepatectomy of the native liver. Subsequently, in order to implement a fast regeneration of the transplanted segments a portal flow diversion is operated in the direction of the future remnant. After obtaining a fast regeneration of the auxiliary future remnant liver the native liver hepatectomy is completed as in a two stage- hepatectomy. Peculiar inclusion criteria will be adopted for patient selection with particular reference to the admission of patients with <3 lung metastases radically treated before transplantation.
I-FIGS Feasibility Study
Liver CancerHepatocellular Carcinoma1 moreBackground: Removal of part of the liver (resection) is performed as a treatment for some cancers in the liver. To achieve the best possible outcomes, it is important that the cancer is removed completely (R0 resection) (1). Up to 30-50% patients develop recurrence within 2 years of surgery which could be due to incomplete removal of the cancer (2). Various techniques are used by the surgeons to identify the cancer tissue from the normal liver during the surgery so that it can be removed completely. These include examining with the naked eye, having a feel of the tumour, and performing an ultrasound scan. Even with these techniques it is difficult to identify the exact extent of the cancer. Also, the interpretation of the ultrasound scan can be subjective (3). A robust, objective, real-time navigation technique is required which can differentiate cancer from normal tissue. Indocyanine green (ICG) is a dye which when given through the veins, is taken up and retained by cancer cells in the liver and they appear as fluorescent areas as compared to normal liver which appears dark. This principle can be used to identify the cancerous tissue accurately during the surgery and remove it completely (Indocyanine green Fluorescence Image-Guided Surgery: I-FIGS). It can also potentially detect additional tumours which were not identified before the surgery or during the surgery with standard techniques (4,5). However, there is a lack of good quality evidence on the usefulness of I-FIGS in liver surgery, so this needs to be tested in a large group of patients having liver surgery before any recommendations can be made. Research Aim: This initial study aims to assess whether a larger trial evaluating the role of I-FIGS in complete removal of the cancer tissue is feasible. Investigators will assess if patients are willing to take part in the study and whether they can gather relevant clinical outcome data from them all. Investigators will also gather patients' views about this novel technique and participating in the study. Design and methods: This study will involve 40 patients having planned liver surgery for liver tumour/s recruited from University Hospitals, Plymouth. Patients will be randomly allocated to have I-FIGS plus standard surgery or standard liver surgery alone. Patients in the I-FIGS group will have ICG injection 2-4 hrs prior to surgery (0.03-0.05mg/kg dose) on the day of surgery. The surgical planning will be carried out as per the standard approach using the naked eye and intra-operative ultrasound examination. Once this is all recorded, ICG cameras will be switched on, and the additional findings and change to surgical plan will be noted. Focus groups will explore participants experiences of being in the study. This will inform the design of the future larger trial. Patient public involvement: Investigators have involved patients who have had or are having liver surgery in the development of the study. Their views on the technique, trial procedures and outcome measures have been incorporated. They will continue to be involved and advise on the study. Dissemination: Results will be available via research journals and conferences.
