Filter by:Liver transplantation are surgeries associated with important bleeding and often require perioperative red blood cell (RBC) transfusions. Overall, between 20 and 85 % of liver transplant recipients receive at least one RBC transfusion during their surgery. Such transfusions are consistently associated with higher morbidity and mortality, although this causal association is still under debate in many surgical populations. Despite the lack of clear causative association between perioperative transfusions and worse outcomes, minimizing bleeding and transfusions is believed to improve postoperative outcomes. Many perioperative variables are associated with higher blood loss and need for perioperative transfusions: liver disease severity, preoperative anemia and coagulopathy, higher cardiac filling pressures and higher fluid administration, among others. However, few perioperative interventions have been shown to reduce bleeding and transfusion requirements in this population. Among them, the use of intraoperative phlebotomies to reduce portal and hepatic venous pressure during the dissection phase is a promising one, also described in liver resection surgery. To further investigate the effects of intraoperative phlebotomies on intraoperative bleeding, perioperative transfusions and mortality, the Principal Investigator will conduct a retrospective cohort study with a propensity score based causal analysis.
The overarching goal of this research is to use machine learning analysis of high-resolution data-collected by wearable technology-of cardiothoracic surgical patients to assess recovery and detect complications at their earliest stage
Most of Colorectal cancer (CRC) diagnosed are candidates for surgical resection with curative intent, although colorectal surgery is associated with some complications that could be life-threatening. Antibiotic prophylaxis is commonly used prior to the admission for the prevention of postoperative complications. However, this intervention can change the composition of intestinal microbiota and promote adverse inflammatory outcomes in CRC patients after surgery. It seems the combination of different fungal extracts could be beneficial because of their role in gut microbiota modulation and their anti-inflammatory activity. Therefore, the fungal extract nutraceutical MICODIGEST 2.0 could be used to reduced the complications after CRC surgery. Based on this hypothesis, we have designed a double-bind randomized clinical trial to evaluate the effect of MICODIGEST 2.0 on the complications after surgery with curative intent for CRC.
The investigators would like to explore whether Hypotension Prediction Index during and immediately after surgery can be used to improve the accuracy of scores that predict postoperative problems.
A five classes (A-E) aggregate risk score predicting 90-day mortality after video-assisted thoracoscopic lobectomy for lung cancer, including as independent factors male sex (3 points), carbon monoxide lung diffusion capacity <60% (1 point) and operative time >150 minutes (1 point), has been recently published. This study aims to assess the effectiveness and reliability of this risk model in a large, independent cohort of patients, in order to confirm its generalizability.
Cancer patients have an increased risk of perioperative complications undergoing surgery procedures. Postoperative complications caused by thrombembolic events after robot- assisted surgery in major urological procedures have been reported and associated with an increased lenght of stay in the hospital. We therefore aimed to investigate in a retrospective analysis 250 patients undergoing robotic-assisted radical cystectomy and prostatectomy procedures for risk factors for thrombembolic events in this specific patient population.
COVID-19 has been a challenge for hospitals; there was an obvious need to reconvert many spaces in specific areas to attend this pathology, without forgetting the attention to other pathologies and surgery. The objective of the investigators is to evaluate the impact of this pandemic in the patients who underwent surgery in Bellvitge University Hospital, analyzing 2 periods of time: the months before the COVID-19 peak and the COVID-19 peak months.
The purpose of the study is to assess feasibility of future large randomised controled study aimed on assessment of effect of goal-directed therapy on incidence of complications in neurosurgery compared to standard care.
This study examined long-term incidence rates of major bleeding associated with hepatectomy. The investigators used data from Taiwan's National Health Insurance Research Database. Patients who underwent hepatectomy between 2000 and 2012 were identified by International Classification of Diseases, Ninth Revision, Clinical Modification codes. Variables including gender, age, comorbidities, and prescribed medications were matched between cases and controls. A total of 1,053 patients with hepatectomy and 4,212 matched non-hepatectomy subjects were included in this study.
This study was conducted as a randomized controlled trial in order to determine the effect of prophylactic negative pressure wound therapy for the prevention of surgical site complications in high-risk colorectal cancer surgery. Hypothesis: Prophylactic negative pressure wound therapy applied after open colorectal cancer surgery to high-risk patients affects surgical wound complications. pNBYT group: The study was completed with a total of 50 patients, 24 of intervention group anda 26 of the control group, who met the inclusion criteria at the surgical oncology service of a university hospital. The data were collected using Patient Identification Form, Surgical Procedure Form, Wound Follow-up Chart and ASEPSİS Wound Scoring System. Ethics committee approval and written informed consent of the individuals was taken in the research. The data were analyzed in SPSS Statistics 24.0 program using Shapiro Wilk test and Q-Q graphs, Independent Sample t test, Mann Whitney U test, Chi-square, Cochran's Q and Friedman test. The value of p<0.05 was accepted for the statistical significance level. It was determined that the groups were similar in terms of identification and surgical procedure characteristics.
