Overview

This research started with the development of a system combining manometry and video fluoroscopy to enable a more detailed analysis of oesophageal manometry data. The first stages of the work were submitted as an MSc in 1996. Although fluoromanometry has been previously carried out using perfusion based manometry systems the goal was to develop a system that could be used in every day clinical practice using miniature strain gauge based manometry system and digital video recording.

This was followed by further developments of the system and a clinical study of fluoromanometry data from 25 patients, this formed the core of the research presented as a PhD thesis in 2000. This work included looking at mechanisms of modelling the system of excitation of the oesophagus and examining the complexity of the signals and information gained from the study. It also includes some simple modelling examining the parameters that need to be measured to quantify acid clearance, levels and swallowing efficiency. The thesis finishes with an examination of some new techniques that may be useful in future oesophageal and GI studies

Notes to readers

I would be grateful for any comments regarding the results and work presented here. It is of note that there is little evidence of medical engineers and physical scientists being involved in GI studies with most research coming from a clinical perspective. The work presented here, although involving a collaboration with clinicians, has followed a more medical engineering based direction of study. It is hoped that this will be of interest to both clinicians and medical engineers and they will be able to follow the arguments and details presented.
