Curative resection remains the only hope of cure for hepatocellular carcinoma (HCC), but postoperative complications can have a significant impact on long-term survival. However, only scarce data on such impact can be found in the literature.This retrospective study reviewed the prospectively collected data of patients who underwent primary liver resection for HCC at our hospital during the period from December 1989 to December 2014. Patients with and without postoperative complications were compared. A 1:1 propensity score matching was adopted by matching age, comorbidity, Model of End-stage Liver Disease score, tumor stage, and extent of resection...

BACKGROUND: A moderate insufflation pressure and deep neuromuscular blockade (NMB) have been recommended in laparoscopic surgery in consideration of the possible reduction in splanchnic perfusion due to the CO2-pneumoperitoneum. Since the liver is the major organ for rocuronium metabolism, the question of whether NMB of rocuronium would change with the variation of liver perfusion during pneumoperitoneum during laparoscopic surgery merits investigation. METHODS: In this prospective study, a total of sixty female patients scheduled for either selective laparoscopic gynaecological surgery (group laparoscopy) or laparotomy for gynaecological surgery (group control) were analyzed...

OBJECTIVE: Microvascular decompression(MVD)surgery has been established as a standard treatment for hemifacial spasm. However, because decompression surgery results in unfavorable outcomes in some cases, a more critical monitoring strategy is required. To improve surgical outcome for hemifacial spasms, abnormal muscle response(AMR)has been proposed as a tool for intraoperative electrophysiological monitoring during MVD surgery. Here, we report a single case of surgical MVD monitoring using artery wall stimulating electromyography(AWS-EMG)...

BACKGROUND: Multimodal analgesia inclusive of periarticular injection with a local anesthetic agent has been rapidly assimilated, with demonstrated safety and efficacy, into the care of patients undergoing elective lower-extremity arthroplasty. The present study was performed to evaluate the efficacy and safety of a surgical-site, multimodal drug injection for postoperative pain control following operative management of femoral fractures. METHODS: There were 102 patients undergoing operative intervention (plate fixation, intramedullary device, or arthroplasty) for a broad range of femoral fracture patterns who were prospectively randomized either to receive an intraoperative, surgical-site injection into the superficial and deep tissues containing ropivacaine, epinephrine, and morphine or to receive no injection...

OBJECTIVE: Reviewing our experience in intracranial video-EEG monitoring in the presurgical evaluation of patients with refractory epilepsy. METHODS: We report on 62 out of 202 (31%) patients with refractory epilepsy, who underwent a long term video-EEG monitoring (LTM). The epileptogenic zone (EZ) was localised either based on the results of LTM or after intracranial EEG recordings from depth, subdural or foramen ovale electrodes. The decision on the location of the electrodes was based upon semiology of the seizures, EEG findings and the lesions visualised in MRI brain scan...

The neonatal brain is extremely vulnerable to injury during periods of hypoxia and/or ischemia. Risk of brain injury is increased during neonatal cardiac surgery, where pre-existing hemodynamic instability and metabolic abnormalities are combined with long periods of low cerebral blood flow and/or circulatory arrest. Our understanding of events associated with cerebral hypoxia-ischemia during cardiopulmonary bypass (CPB) remains limited, largely due to inadequate tools to quantify cerebral oxygen delivery and consumption non-invasively and in real-time...
