Future Developments of the Valtrac/Biofragmentable Anastomosis Ring Device

Colorectal cancer is the most common indication for large-bowel surgery, and 60% of such tumours occur in the rectum and sigmoid colon. To date, approximately 50000 Valtrac biofragmentable anastomosis ring (BAR) devices (Davis and Geck, USA) have been used for forming anastomosis in the gastrointestinal tract from the level of the oesophagus to the upper rectum. Since the Valtrac has proved very successful as an anastomotic device, a natural progression in its history is the development of a transanal applicator to facilitate its insertion for rectal anastomosis. Such a device would also allow the assessment of the possibility of using a Valtrac BAR for a low rectal anastomosis. With this in mind, the research department at Davis and Geck, Richmond, UK, has devised a series of instruments for the transanal insertion of a Valtrac BAR device.
