BACKGROUND: The aim of this study was to compare the efficacy of laparoscopic liver resection versus radiofrequency ablation for treatment of small hepatocellular carcinoma. METHODS: This single-centre RCT was conducted at a tertiary referral centre in China. Patients with small hepatocellular carcinoma who had a single nodule no larger than 5 cm, or up to three nodules of 3 cm or smaller, were eligible. Patients were assigned randomly in a 1 : 1 ratio to either laparoscopic liver resection or radiofrequency ablation...

BACKGROUND: Preoperative anaemia is common in patient undergoing colorectal surgery. Understanding the population-level costs of preoperative anaemia will inform development and evaluation of anaemia management at health system levels. METHODS: This was a population-based cohort study using linked, routinely collected data, including residents from Ontario, Canada, aged ≥18 yr who underwent an elective colorectal resection between 2012 and 2022. Primary exposure was preoperative anaemia (haemoglobin <130 g L-1 in males; <120 g L-1 in females)...

BACKGROUND: Major surgery is associated with high complication rates. Several risk scores exist to assess individual patient risk before surgery but have limited precision. Novel prognostic factors can be included as additional building blocks in existing prediction models. A candidate prognostic factor, measured by cardiopulmonary exercise testing, is ventilatory efficiency (VE/VCO2 ). The aim of this systematic review was to summarise evidence regarding VE/VCO2 as a prognostic factor for postoperative complications in patients undergoing major surgery...

Many patients undergoing surgical procedures have a history of hypertension, diabetes mellitus, heart failure, or a combination. Often, these conditions involve the chronic use of a renin-angiotensin system inhibitor, including angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs). Observational studies have suggested that continuing ACEIs/ARBs before major noncardiac surgery can increase the risk of intraoperative hypotension, which might drive postoperative complications such as acute kidney injury, myocardial injury, or stroke...

The conduct and reporting of studies with a noninferiority hypothesis is challenging because of the complexity involved in their design and interpretation. However, studies with a noninferiority design have increased in popularity. A recently published trial reported on the noninferiority of lidocaine infusion to epidural analgesia in major abdominal surgeries. Apart from needing a critical appraisal, this draws attention to improve our understanding of noninferiority study framework and its unique features...

It is important to be able to measure the range of clear focus in clinical practice to advise on presbyopia correction techniques and to optimise the correction power. Both subjective and objective techniques are necessary: subjective techniques (such as patient reported outcome questionnaires and defocus curves) assess the impact of presbyopia on a patient and how the combination of residual objective accommodation and their natural DoF work for them; objective techniques (such as autorefraction, corneal topography and lens imaging) allow the clinician to understand how well a technique is working optically and whether it is the right choice or how adjustments can be made to optimise performance...

OBJECTIVE: To evaluate the accuracy of self-reported conflicts of interest (COIs) for articles published in prominent minimally invasive and general surgical journals. BACKGROUND: Accurate reporting of industry relationships and COIs is crucial for unbiased assessment of a particular study. Despite the enactment of COI laws, such as the Physician Payments Sunshine Act in 2010, prior work suggests that 40-70% of self-reported COIs have discrepancies. METHODS: We utilized three public databases -- Open Payments (USA), Disclosure UK, and Disclosure Australia -- to assess the accuracy of COI disclosures among authors of 918 published articles from these respective countries...

BACKGROUND: Machine perfusion is an organ preservation strategy used to improve function over simple storage in a cold environment. This article presents an updated systematic review and meta-analysis of machine perfusion in deceased donor kidneys. METHODS: RCTs from November 2018 to July 2023 comparing machine perfusion versus static cold storage in kidney transplantation were evaluated for systematic review. The primary outcome in meta-analysis was delayed graft function...

Facial transplantations have become a clinical reality as the last reconstructive option in severely disfigured patients. To date, clinical outcomes remain unclear. The purpose of this paper was to analyse the outcomes in facial transplantation (FT) and determine the risks and benefits of FT based on short- and long-term outcomes. An electronic literature search was performed across PubMed, EMBASE and the Cochrane Central Register for Controlled Trials (CENTRAL) databases to capture all the relevant records relating to outcomes in FTs from 2005 to 2021...

The parasymphysis area of the mandible is highly dynamic because it is subjected to both occlusal and muscular forces. As a result, the fractures in this transition zone have a special pattern, posing a challenge for surgeons whether to use one miniplate versus two miniplates, as per Champy's recommendations. The commonest complication resulting to treat this area is mental nerve paraesthesia due to the dissection and stretching of the nerve. Hence, an in vitro research study of a newly designed 'Zeta' miniplate is performed, to evaluate the biomechanical behaviour using finite element (FE) analysis and biomechanical analysis along with a comparison study with the conventional miniplate configurations...

The anatomically complex craniofacial skeleton demands special consideration when caring for cases of polytrauma or medically compromised patients with craniofacial fractures. This paper utilises a systematic review and multidisciplinary opinions to create an algorithm for the hospital-based care of patients with craniofacial fractures (base of skull, orbit, paranasal sinus, and mandible) who require non-invasive ventilation (NIV). Each fracture location has a unique predisposition to a different type of emphysema and associated morbidity...

BACKGROUND: Dexmedetomidine utilisation in paediatric patients is increasing. We hypothesised that intraoperative use of dexmedetomidine in children is associated with longer postanaesthesia care unit length of stay, higher healthcare costs, and side-effects. METHODS: We analysed data from paediatric patients (aged 0-12 yr) between 2016 and 2021 in the Bronx, NY, USA. We matched our cohort with the Healthcare Cost and Utilization Project-Kids' Inpatient Database (HCUP-KID)...

INTRODUCTION: Cardiac complications after major noncardiac surgery are common and associated with high morbidity and mortality. How preoperative use of beta-blockers may impact perioperative cardiac complications remains unclear. METHODS: In a multicentre prospective cohort study, preoperative beta-blocker use was ascertained in consecutive patients at elevated cardiovascular risk undergoing major noncardiac surgery. Cardiac complications were prospectively monitored and centrally adjudicated by two independent experts...
