International consensus to define outcomes for trials of chemoradiotherapy for anal cancer (CORMAC-2): defining the outcomes from the CORMAC core outcome set.

Variation in outcomes definitions and reporting limit the utility of clinical trial results. The Core Outcome Research Measures in Anal Cancer (CORMAC) project developed a core outcome set (COS) for chemoradiotherapy trials for anal squamous cell carcinoma (ASCC) through an international healthcare professional and patient consensus process. The CORMAC-COS comprises 19 outcomes across 4 domains (disease activity, survival, toxicity, life impact).

An Approach for Combining Clinical Judgment with Machine Learning to Inform Medical Decision Making: Analysis of Nonemergency Surgery Strategies for Acute Appendicitis in Patients with Multiple Long-Term Conditions.

Background: Machine learning (ML) methods can identify complex patterns of treatment effect heterogeneity. However, before ML can help to personalize decision making, transparent approaches must be developed that draw on clinical judgment. We develop an approach that combines clinical judgment with ML to generate appropriate comparative effectiveness evidence for informing decision making.

Surgeon perceptions of personality as an influencing factor on anastomotic decision-making: A qualitative analysis.

Aim: Surgeon personality is a factor influencing rectal anastomotic decision-making. However, it is unclear how or why this may be the case, or what aspects of personality are involved. The aim of this study was to investigate the views of colorectal surgeons on how their individual personality may influence variation in anastomotic decision-making.

Psychosocial outcomes following emergency laparotomy (POLO) study: a study protocol for a multicentre mixed-methods prospective cohort study assessing the psycho-social outcomes following emergency laparotomy in adults.

Introduction: Morbidity from an emergency laparotomy (EmLap) is difficult to define and poorly understood. Morbidity is a holistic concept, reliant upon an interplay of bio-psychosocial outcomes that evolve long after discharge. To date, no previous study has explored the psychosocial outcomes following EmLap as a collective, nor their change over time.

The management of complicated colorectal cancer in older patients in a global perspective after COVID-19: the CO-OLDER WSES project.

Background: Colorectal (CRC) cancer is becoming a disease of the elderly. Ageing is the most significant risk factor for presenting CRC. Early diagnosis of CRC and management is the best way in achieving good outcomes and longer survival but patients aged ≥75 years are usually not screened for CRC.

Dissecting the surgeon's personality: cross-cultural comparisons in Western Europe.

Aim: The surgeon's personality contributes to variation in surgical decision-making. Previous work on surgeon personality has largely been reserved to Anglo-Saxon studies, with limited international comparisons. In this work we built upon recent work on gastrointestinal surgeon personality and aimed to detect international variations.

Appendectomy versus antibiotic treatment for acute appendicitis.

Background: Acute appendicitis is one of the most common emergency general surgical conditions worldwide. Uncomplicated/simple appendicitis can be treated with appendectomy or antibiotics. Some studies have suggested possible benefits with antibiotics with reduced complications, length of hospital stay, and the number of days off work.

International consensus is needed on a core outcome set to advance the evidence of best practice in cancer prehabilitation services and research.

Prehabilitation aims to optimise patients' physical and psychological status before treatment. The types of outcomes measured to assess the impact of prehabilitation interventions vary across clinical research and service evaluation, limiting the ability to compare between studies and services and to pool data. An international workshop involving academic and clinical experts in cancer prehabilitation was convened in May 2022 at Sheffield Hallam University's Advanced Wellbeing Research Centre, England.

Postoperative outcomes and identification of risk factors for complications after emergency intestinal stoma surgery - a multicentre retrospective study.

Aim: Approximately 4000 patients in the UK have an emergency intestinal stoma formed each year. Stoma-related complications (SRCs) are heterogeneous but have previously been subcategorized into early or late SRCs, with early SRCs generally occurring within 30 days postoperatively. Early SRCs include skin excoriation, stoma necrosis and high output, while late SRCs include parastomal hernia, retraction and prolapse.

Influencing factors in surgical decision-making: a qualitative analysis of colorectal surgeons' experiences of postoperative complications.

Aim: When making anastomotic decisions in rectal cancer surgery, surgeons must consider the risk of anastomotic leakage, which bears implications for the patient's quality of life, cancer recurrence and, potentially, death. The aim of this study was to investigate the views of colorectal surgeons on how their individual attributes (e.g.

Validation of the emergency surgery score (ESS) in a UK patient population and comparison with NELA scoring: a retrospective multicentre cohort study.

Introduction: Accurate risk scoring in emergency general surgery (EGS) is vital for consent and resource allocation. The emergency surgery score (ESS) has been validated as a reliable preoperative predictor of postoperative outcomes in EGS but has been studied only in the US population. Our primary aim was to perform an external validation study of the ESS in a UK population.

SF-CORNER (splenic flexure colorectal cancer): an international survey of operative approaches and outcomes for cancers of the splenic flexure.

Aim: The optimum surgical approach to splenic flexure cancers (SFCs) remains uncertain. The aim of this survey was to explore the opinions of an international surgical community on the management and outcomes of SFC.

Method: A questionnaire was constructed comprising five sections (information about respondents; definition and prognosis of SFC; operative approach; approach in specific scenarios; outcomes) and circulated through an international dissemination committee and social media.

Beyond high-risk: analysis of the outcomes of extreme-risk patients in the National Emergency Laparotomy Audit.

Patients who require emergency laparotomy are defined as high risk if their 30-day predicted risk of mortality is ≥ 5%. Despite a large difference in the characteristics of patients with a mortality risk score of between 5% and 50%, these outcomes are aggregated by the National Emergency Laparotomy Audit (NELA). Our aim was to describe the outcomes of the cohort of patients at extreme risk of death, which we defined as having a NELA-predicted 30-day mortality of ≥ 50%.

Patient-reported impact of emergency laparotomy on employment and health status 1 year after surgery.

Background: Whilst there has been significant improvement in mortality outcomes after emergency laparotomy, there is little information on longer term outcomes in the year after discharge. The main aim of the study was to assess the impact that an emergency laparotomy has on patients' and employment and health status 1 year after surgery.

Methods: This study was a questionnaire study conducted in a single centre district general hospital of patients who had undergone an emergency laparotomy between October 2015 and December 2016.

Investigation of frailty markers including a novel biomarker panel in emergency laparotomy: protocol of a prospective cohort study.

Background: Emergency laparotomy (EmLAP) is one of the commonest emergency operations performed in the United Kingdom (approximately 30, 000 laparotomies annually). These potentially high-risk procedures can be life changing with frail patients and/ or older adults (≥ 65 years) having the poorest outcomes, including mortality. There is no gold standard of frailty assessment and no clinical chemical biomarkers existing in practice.

Collaboration is key: the role of social media in advancing surgical research.

Social media has revolutionized how we design, deliver, and disseminate surgical research for the better. The rise of collaborative research groups has been a major contributor to and beneficiary of social media, leading to increased involvement from clinicians, medical students, healthcare professionals, patients, and industry. Everyone benefits from collaborative research by widening access and participation and delivering more impactful research with increasing validity of results applicable to global populations.

The impact of intestinal stoma formation on patient quality of life after emergency surgery-A systematic review.

Aim: Elective stoma formation has a negative effect on patient quality of life (QoL), with a potential detrimental impact on body image, confidence and social functioning being shown previously. However, the impact of emergency stoma formation on QoL has been explored less frequently. This systematic review aims to synthesize all available literature exploring QoL via patient-reported outcome measures.

CT-derived measures of muscle quantity and quality predict poorer outcomes from elective colorectal surgery: a UK multicentre retrospective cohort study.

Purpose: To assess whether preoperative radiologically defined lean muscle measures are associated with adverse clinical outcomes in patients undergoing elective surgery for colorectal cancer.

Methods: This retrospective UK-based multicentre data collection study identified patients having had colorectal cancer resection with curative intent between January 2013 to December 2016. Preoperative computed-tomography (CT) scans were used to measure psoas muscle characteristics.

Adapting Patient and Public Involvement processes in response to the Covid-19 pandemic.

Background: The COVID-19 pandemic brought rapid and major changes to research, and those wishing to carry out Patient and Public Involvement (PPI) activities faced challenges, such as restrictions on movement and contact, illness, bereavement and risks to potential participants. Some researchers moved PPI to online settings during this time but remote consultations raise, as well as address, a number of challenges. It is important to learn from PPI undertaken in this period as face-to-face consultation may no longer be the dominant method for PPI.

Quantitative futility in emergency laparotomy: an exploration of early-postoperative death in the National Emergency Laparotomy Audit.

Background: Quantitative futility is an appraisal of the risk of failure of a treatment. For those who do not survive, a laparotomy has provided negligible therapeutic benefit and may represent a missed opportunity for palliation. The aim of this study was to define a timeframe for quantitative futility in emergency laparotomy and investigate predictors of futility using the National Emergency Laparotomy Audit (NELA) database.
