In the era of minimally invasive surgery (MIS), parenchyma-preserving liver resections are gaining prominence with the potential to offer improved perioperative outcomes without compromising oncological safety. The surgeon learning curve remains challenging, and simulation plays a key role in surgical training. Existing simulation models can be limited by suboptimal fidelity and high cost. We describe a novel, reproducible, high-fidelity, low-cost liver metastases model using porcine livers from adult Landrace pigs, with porcine perinephric fat used to simulate subcapsular metastases. This model was then utilised in a training session for surgical trainees performing robotic parenchyma-preserving surgery (PPS) under the guidance of expert robotic surgeons, with feedback being recorded. Trainees rated the model highly on its fidelity to human liver simulation (median score 9), tissue handling (median score 8), and overall usefulness (median score 9). Tissue handling was felt to simulate in vivo liver resection closely, while suggestions for improvement included adding simulated blood flow. This is a novel, low-cost, high-fidelity simulation model of liver metastases with high acceptability to surgical trainees, which could be readily adopted by other training centres.

Aims This study focuses on the assessment of patient reported outcome measures (PROMs) following an educational intervention by urological service providers. In the modern era, social media and search engines are used as educational tools for both patients and healthcare providers alike. The aim of the study was to assess patient satisfaction with kidney stone information, through the viewing of a novel kidney stone educational video. Methods A prospective quality improvement study was conducted amongst patients admitted to our urology service with kidney stones undergoing emergency ureteroscopy using a patient satisfaction questionnaire. Results Patients reported increased satisfaction with overall information provided about kidney stone prevention after viewing the kidney stone educational video (4.8 vs 4 p=0.01). They also reported increased satisfaction with information provided about diet and lifestyle modification (4.5 vs3 p=0.02) (4.6 vs 3 p=0.02), information and demonstration on stent removal 4.8 vs 3.17 p=0.029), information on stent pain (4.7 vs 2.6 P=0.016) and availability of educational information and resources after viewing the video (4.8 vs 2.83 p=0.017). There were 17 patients in total included for statistical analysis. Conclusion Patient satisfaction with traditional patient education regarding kidney stones can be further strengthened through the use of a concise, informative, and readily accessible patient education video during and after point of care., Competing Interests: The authors have no conflicts of interest to declare.
