Clinical Performance Status and Technical Factors Affecting Outcomes from Percutaneous Transhepatic Biliary Interventions; A Multicentre, Prospective, Observational Cohort Study.

PURPOSE: The purpose of this study was to evaluate the predictive value of a 'Modified Karnofsky Scoring System' on outcomes and provide real-world data regarding the UK practice of biliary interventions. MATERIALS AND METHODS: A prospective multi-centred cohort study was performed. The pre-procedure modified Karnofsky score, the incidence of sepsis, complications, biochemical improvement and mortality were recorded out to 30 days post procedure. RESULTS: A total of 292 patients (248 with malignant lesions) were suitable for inclusion in the study. The overall 7 and 30 day mortality was 3.1% and 16.1%, respectively. The 30 day sepsis rate was 10.3%. In the modified Karnofsky 'high risk' group the 7 day mortality was 9.7% versus 0% for the 'low risk' group (p = 0.002), whereas the 30 day mortality was 28.8% versus 13.3% (p = 0.003). The incidence of sepsis at 30 days was 19% in the high risk group versus 3.3% at the low risk group (p = 0.001) CONCLUSION: Percutaneous biliary interventions in the UK are safe and effective. Scoring systems such as the Karnofsky or the modified Karnofsky score hold promise in allowing us to identify high risk groups that will need more careful consideration and enhanced patient informed consent but further research with larger studies is warranted in order to identify their true impact on patient selection and outcomes post biliary interventions.

Pain Management Protocols During Uterine Fibroid Embolisation: A Systematic Review of the Evidence.

BACKGROUND: Uterine fibroid embolisation (UFE) is an effective treatment for fibroids. There are varying analgesia protocols published to control procedure associated pain. We aimed to assess what protocols are most effective in controlling post-procedural pain. MATERIALS AND METHODS: A systematic review of the Embase and Medline databases was conducted according to PRISMA guidelines. Studies regarding analgesia protocols post-uterine fibroid embolisation with Visual Analogue Scale or Numerical Rating Scale pain scores were included. The mean maximal pain scores of patients post-procedure were evaluated. ANOVA and t tests were performed. RESULTS: We identified 26 studies (total 3353 patients), with a mean procedural success rate of > 87%. We stratified protocols into four groups. Mean pain scores were: opioids ± NSAIDs ± acetaminophen (4.84, SD = 1.56); opioids ± NSAIDs ± acetaminophen + nerve block (4.7, SD = 1.37); opioids ± NSAIDs ± acetaminophen + intrauterine artery drug administration (4.09, SD = 0.60); and opioids ± NSAIDs ± acetaminophen + other (5.30, SD = 1.13) without significant difference between groups (p = 0.71). Similarly, there was no difference (p = 0.057) between groups for time to discharge or side effects. CONCLUSIONS: There is no evidence to suggest that there is any superiority of one protocol above another in the published literature. Appropriate use of opioids ± NSAIDs ± acetaminophen alone appears to be sufficient to control pain post-UFE. However, due to large heterogeneity of the literature no firm conclusions can be reached, and further research is warranted. LEVEL OF EVIDENCE: Level 1, Systematic review.
