COmparing Urolift and Standard Transurethral resection of prostate Ahead of Radiotherapy in men with urinary symptoms secondary to prostate enlargement in Southwest London and North Cumbria (CO-STAR): a study protocol for a randomised feasibility study.

INTRODUCTION: Patients undergoing prostate radiotherapy with an enlarged prostate can have short-term and long-term urinary complications. Currently, transurethral resection of the prostate (TURP) is the mainstay surgical intervention for men with urinary symptoms due to an enlarged prostate prior to radiotherapy. UroLift (NeoTract, Pleasanton, CA, USA) is a recent minimally invasive alternative, widely used in benign disease but is untested in men with prostate cancer. METHODS AND ANALYSIS: A multicentre, two-arm study designed in collaboration with a Patient Reference Group to assess the feasibility of randomising men with prostate cancer and coexisting urinary symptoms due to prostate enlargement to TURP or UroLift ahead of radiotherapy. 45 patients will be enrolled and randomised (1:1) using a computer-generated programme to TURP or UroLift. Recruitment and retention will be assessed over a 12 month period. Information on clinical outcomes, adverse events and costs will be collected. Clinical outcomes and patient reported outcome measures will be measured at baseline, 6 weeks postintervention and 3 months following radiotherapy. A further 12 in-depth interviews will be conducted with a subset of patients to assess acceptability using the Theoretical Framework of Acceptability. Descriptive analysis on all outcomes will be performed using Stata (StataCorp V.2021). ETHICS AND DISSEMINATION: The trial has been approved by the Research Ethics Committee (REC) NHS Health Research Authority (HRA) and Health and Care Research Wales (HCRW). The results will be published in peer-reviewed journals, presented at national meetings and disseminated to patients via social media, charity and hospital websites. TRIAL REGISTRATION NUMBER: NCT05840549.

The 'hub and spoke model' for the management of surgical patients during the COVID-19 pandemic.

During the on-going COVID-19 pandemic a number of key public health services have been severely impacted. These include elective surgical services due to the synergetic resources required to provide both perioperative surgical care whilst also treating acute COVID-19 patients and also the poor outcomes associated with surgical patients who develop COVID-19 in the perioperative period. This article discusses the important principles and concepts for providing important surgical services during the COVID-19 pandemic based on the model of the RMCancerSurgHub which is providing surgical cancer services for a population of approximately 2 million people across London during the pandemic. The model focusses on creating local and regional hub centres which provide urgent treatment for surgical patients in an environment that is relatively protected from the burden of COVID-19 illness. The model extensively utilises the extended multidisciplinary team to allow for a flexible approach with core services delivered in 'clean' sites which can adapt to viral surges. A key requirement is that of a clinical prioritisation process which allows for equity in access within and between specialties ensuring that patients are treated on the basis of greatest need, while at the same time protecting those whose conditions can safely wait from exposure to the virus. Importantly, this model has the ability to scale-up activity and lead units and networks into the recovery phase. The model discussed is also broadly applicable to providing surgical services during any viral pandemic.

Shared perioperative decision making: a shift in the doctor-patient paradigm.

The high-risk surgical patient only constitutes approximately 4% of the elective non-cardiac surgical population but contributes to the vast majority of in-hospital deaths following surgery. This, in conjunction with a high morbidity rate, can lead to a perioperative pathway fraught with challenges. It is incredibly difficult to anticipate which complications may arise and the risks involved before surgery. It is for this reason that patients need to be engaged in the decision-making processes regarding their perioperative care involved before major surgery. A combination of good medical practice, medicolegal influences and a governmental drive have begun to result in a shift away from paternalistic medicine to a shared decision-making approach. This article defines shared decision making, explores its benefits and limitations and addresses the relevant legal literature.

A clinician's guide to viscoelastic testing in the perioperative period.

Viscoelastic tests provide a global and dynamic assessment of the coagulation system and thus are becoming increasingly relied upon in the perioperative period. Many clinicians are unfamiliar with viscoelastic testing, so this article provides an overview of their use and interpretation in the management of perioperative bleeding.

Cardiopulmonary exercise testing for predicting postoperative morbidity in patients undergoing hepatic resection surgery.

OBJECTIVES: Cardiopulmonary exercise testing (CPET) may predict which patients are at risk for adverse outcomes after major abdominal surgery. The primary aim of this study was to determine whether CPET variables are predicative of morbidity. METHODS: High-risk patients undergoing elective, one-stage, open hepatic resection were preoperatively assessed using CPET. Morbidity, as defined by the Postoperative Morbidity Survey (POMS), was assessed on postoperative day 3. RESULTS: A total of 104 patients underwent preoperative CPET and were included in the analysis. Of these, 73 patients (70.2%) experienced postoperative morbidity. Oxygen consumption at anaerobic threshold (V˙O2 at AT, ml/kg/min) was the only CPET predictor of postoperative morbidity on multivariable analysis, with an area under the curve (AUC) of 0.66 [95% confidence interval (CI) 0.55-0.76]. In patients requiring a major hepatic resection (three or more segments), a V˙O2 at AT of <10.2 ml/kg/min gave an AUC of 0.79 (95% CI 0.68-0.86) with 83.9% sensitivity and 52.0% specificity, 80.6% positive predictive value and 62.5% negative predictive value. CONCLUSIONS: The application of a cut-off value for V˙O2 at AT of <10.2 ml/kg/min in patients undergoing major hepatic resection may be useful for predicting which patients will experience morbidity.

A prospective cohort study of intrathecal versus epidural analgesia for patients undergoing hepatic resection.

BACKGROUND: The aim of this prospective observational study was to compare peri/post-operative outcomes of thoracic epidural analgesia (TEA) versus intrathecal morphine and fentanyl patient-controlled analgesia (ITM+fPCA) for patients undergoing a hepatic resection (HR). METHOD: Patients undergoing elective, one-stage, open HR for benign and malignant liver lesions, receiving central neuraxial block as part of the anaesthetic, in a high-volume hepato-pancreato-biliary unit, were included in the study. The primary outcome measure was post-operative length of stay (LoS). RESULTS: A total of 73 patients (36 TEA and 37 ITM+fPCA) were included in the study. The median (IQR) post-operative LoS was 13 (11-15) and 11 (9-13) days in the TEA and ITM+fPCA groups, respectively (P = 0.011). There was significantly lower median intra-operative central venous pressure (P < 0.001) and blood loss (P = 0.017) in the TEA group, and a significant reduction in the time until mobilization (P < 0.001), post-operative intra-venous fluid/vasopressor requirement (P < 0.001/P = 0.004) in the ITM+fPCA group. Pain scores were lower at a clinically significant level 12 h post-operatively in the TEA group (P < 0.001); otherwise there were no differences out to day five. There were no differences in quality of recovery or postoperative morbidity/mortality between the two groups. CONCLUSION: ITM+fPCA provides acceptable post-operative outcomes for HR, but may also increase the incidence of intra-operative blood loss in comparison to TEA.
