Sony OLED Surgical Monitor Case Study

St. Richards Hospital (SRH) in Chichester has taken the next step in the surgical imaging field by introducing Sony’s ground-breaking 25” OLED monitor (PVM-2551MD). It’s the first solution of its kind in the medical sector that harnesses Sony TRIMASTER EL™ technology to provide the stability of colour imaging and high quality contrast to enhance surgical viewing. Leading surgeon Mr. Guy Slater and his team were the first to pilot trial the displays and have benefited from their superior contrast, virtually non-existent blur and more faithful colour reproduction, relative to LCD. Background: St Richard's Hospital is a medium-sized District General Hospital (DGH) located in Chichester, West Sussex, England. SRH has one of the most advanced bariatric surgery departments in the UK that provides specialist surgical weight loss treatment for obese patients. The service was established at St Richard's Hospital in May 2006 and now attracts patients from all over the country who benefit from the specialist care of the hospital's skilled staff. As the largest NHS centre for the bariatric surgery in the South of England, the hospital currently treats over 200 patients a year. Challenge: The bariatric division at SRH is the busiest department in the UK, with a high flow of patients. Mr. Slater Individually operates on 150 – 200 patients a year and 95 % of the surgery that he undertakes is laparoscopic (also called minimally invasive surgery) using monitors and stacks – the hospital does very little conventional open surgery. For that reason, Mr Slater and his department required a technological solution that would enable them to distinguish even the most subtle differences between tissues and blood vessels that can affect an outcome of weight loss surgery. Mr Slater explained: “Display technology is very important in what I do. There's no doubt that having the latest high definition monitors improves the picture quality so I can better see the structures I need to see to perform surgery more accurately. The thought of going back to LCD technology would feel like a step backwards now that I’ve experienced the clarity OLED brings.” The Sony Solution: St Richard’s Hospital needed a solution that would empower its surgeons with the highest quality images. Therefore, Sony provided SRH with 4 PVM-2551MD displays which combine full HD resolution (1,920 x 1,080 pixels) with 10-bit signal processing for accurate colour management and unrivalled image quality. OLED monitors are used particularly in both rigid and flexible endoscopy as well as surgical microscopy procedures to allow the surgeon to see subtle tissue differentiation in low light conditions. Sony’s OLED monitor provides maximum resolution and ultimate precision in image reproduction. Commenting on the installation, John Strudwick of Richard Wolf - specialists in endoscopic cameras who work in partnership with Sony Medical, stated: “Sony’s OLED technology provides the clearest possible image so surgeons can work quickly and efficiently. As a specialist in endoscopic cameras, I can say with confidence that Sony is head and shoulders above its competition. In combination with our modern HD endoscopy cameras, customers like Mr. Slater can recognise even the smallest details, such as in screening for early indications of cancer, in detecting flat lesions, or in differentiating tumours seamlessly in a medical environment.” Why Sony was selected: SRH required a cutting-edge technological solution that would enable them to operate efficiently, educate their trainees effectively on how to provide the highest quality bariatric care as well as helping them to develop their own operating techniques. Sony provided best of breed technology solution to meet those needs, combined with expert consultancy, which was a major driver behind SRH’s investment in OLED. SRH decided to make the transition from its LCD monitors to Sony’s OLED displays as part of an upgrade process for the laparoscopic stacks that they previously used. The hospital was presented with the opportunity of a side-by-side comparison and found Sony's OLED technology provided the clearest possible image to work quickly and efficiently, thus improving the accuracy of surgery. John Herman, European Trade Marketing Manager – Surgical atSony Medical, commented: “OLED is definitely the future for surgical imaging. Surgeons need the best picture quality to be able to perform at their highest standard. I have visited many surgeons having performed side by side comparisons with both OLED and LCD monitors. The feedback that we’ve been given is that OLED is the clear winner.” The Result: Commenting on the significant impact the introduction of OLED technology has had, Mr Salter said: “OLED makes surgery easier, more accurate and much less stressful. The benefits for me are three fold: It handles colour better which makes the surgery more accurate. The speed the image can cope with movement is excellent – you never get blurring as your move the telescope around the abdomen. The ability to work in low light, particularly if you’ve got bleeding which draws the light away the OLED technology allows me to work more accurately despite sub-optimal conditions.” Mr. Slater concluded: “It's very difficult to quantify an improvement from these [OLED] monitors but every step forward is a better increment in terms of accuracy and picture definition. The technology makes my surgery more accurate. If my surgery is more accurate, it's safer for the patient and certainly reduces my stress levels when I can see properly. I’d very much recommend OLED technology to my colleagues: picture definition is excellent, colour handling is superb and I think it’s the way forward.”
