Oesophageal doppler monitoring (ODM) specialist Deltex Medical Group has welcomed positive results from a study looking at the implementation of ODM in colorectal surgery.The findings have led the hospital where the study was carried out to recommend making the enhanced recovery protocols, including ODM, the default protocol for all colorectal surgeries, with the potential to expand into other surgical areas such as urology and gynaecology.The study, which looked at a wider quality improvement initiative in colorectal surgery conducted at Brigham and Women's Hospital in Boston, found the measures led to a 25% reduction in both the median and mean length of stay.Deltex Medical's chief Ewan Phillips said: "We are delighted that our dedicated trainer programme has helped deliver excellent results from such a high calibre and renowned US hospital as Brigham and Women's.""This convergence of our US platform and market development programmes is important validation of our focused strategy to build our US business towards future national roll-out."Shares had risen 9.23% to 7.10p by 14:16.
