Paper Abstract

The human gastrointestinal tract or ‘gut’ is one of the body’s largest functional systems spanning up to 8 metres in length from beginning to end. It is formed of a series of physiologically different sections that perform the various functions required for the digestion of food, absorption of nutrients and water, and the removal of waste products. To enable the gut to perform correctly it must be able to transport digesta through each section at the appropriate rate, and any breakdown or malfunction of this transport mechanism can have severe consequences to on-going good health.

Monitoring motor function deep within the gut is challenging due to the need to monitor over extended lengths with high spatial resolution. Fiber Bragg grating (FBG) manometry catheters provide a near ideal method of monitoring physiologically significant lengths of the gut in a minimally invasive fashion. Following the development by our group of the first viable FBG based manometry catheter we have undertaken a series of clinical investigations in the human esophagus, colon, stomach and small bowel. Each region presents its own technological challenge and has required a range of modifications to the basic catheter design. We present the design of these catheters and clinical results from over 100 in-vivo studies.
