Patient public perspectives on digital colorectal cancer surgery (DALLAS).

Introduction: The importance of patient perspectives is increasingly appreciated in clinical practice and academia with formal engagement processes developing worldwide. Digital surgery encompasses intraoperative patient data (including surgical video) analysis and so requires public-patient involvement (PPI).

Methods: Engagement events were conducted based on NIHR and GRIPP2 LF guidelines.

Clinical validation of 3D virtual modelling for laparoscopic complete mesocolic excision with central vascular ligation for proximal colon cancer.

Introduction: Laparoscopic Complete Mesocolic Excision (CME) with Central Vascular Ligation (CVL) in colon cancer surgery has not been broadly adopted in part because of safety concerns. Pre-operative 3-D virtual modelling (3DVM) may help but needs validation.

Methods: 3DVM were routinely constructed from CT mesenteric angiograms (CTMA) using a commercial service (Visible Patient, Strasbourg, France) for consecutive patients during our CMECVL learning curve over three years.

Impact of Simulation Training on Core Skill Competency of Undergraduate Medical Students.

Introduction: Simulation based medical training (SBMT) is gaining traction for undergraduate learning and development. We designed, implemented, and independently assessed the impact of an SBMT programme on competency in surgical history taking and clinical examination for senior clinical students.

Methods: With institutional ethical approval and initial pilot study of student volunteers that ensured format appropriateness, we implemented an SBMT programme weekly for ten weeks during the core surgery module of our Medicine degree programme.

Technical and functional design considerations for a real-world interpretable AI solution for NIR perfusion analysis (including cancer).

Near infrared (NIR) analysis of tissue perfusion via indocyanine green fluorescence assessment is performed clinically during surgery for a range of indications. Its usefulness can potentially be further enhanced through the application of interpretable artificial intelligence (AI) methods to improve dynamic interpretation accuracy in these and also open new applications. While its main use currently is for perfusion assessment as a tissue health check prior to performing an anastomosis, there is increasing interest in using fluorophores for cancer detection during surgical interventions with most research being based on the paradigm of static imaging for fluorophore uptake hours after preoperative dosing.

The age of surgical operative video big data - My bicycle or our park?

Background: Surgery is a major component of health-care provision. Operative intervention often employs minimally invasive approaches incorporating digital cameras creating a 'digital twin' of both intracorporeal appearances and operative performance. Video recordings provide richer detail than the traditional operative note and can couple with advanced computer technology to unlock new analytic capabilities capable of driving surgical advancement via quality improvement initiatives and new technology design.

Peroperative personalised decision support and analytics for colon cancer surgery- Short report.

Advanced instrumentation whether robotic or non-robotic- hasn't itself made for better surgery as all critical measures of operative success depend still on intraoperative surgeon judgement and decision-making. Computer assisted surgery, or digital surgery, refers to the combination of technology with real-time data during an operation and is often assumed to need new hardware platforms to become a reality. However, methods to support personalised surgical endeavour exist now and can be deployed today within standard laparoscopic paradigms.

Is There Variability in Scoring of Student Surgical OSCE Performance Based on Examiner Experience and Expertise?

Objective: To investigate the influence of clinical experience and content expertise on global assessment scores in a Surgical Objective Structured Clinical Exam (OSCE) for senior medical undergraduate students.

Design: Scripted videos of simulated student performance in an OSCE at two standards (clear pass and borderline) were awarded a global score on each of two rating scales by a range of clinical assessors. Results were analysed by examiner experience and content expertise.
