Big appetite to probe the stomach By CATHERINE HEALY Stomach modelling: Former Avondale College student Peng Du is writing his PhD at the Auckland University's Bioengineering Institute. He is studying the bioelectrical activity of the stomach. Through computer modelling, electronics and the good will of sur- gical patients, Peng Du is becoming an expert in the function of the human stomach. His computer modelling techniques illustrate the difference between the function of healthy and diseased stomach cells. A diseased stomach may not contract and empty food properly, leaving the patient bloated. It's important because stomach diseases may not kill you right away, but they're chronic and in terms of quality of life they really affect you,'' the Avondale resident says. The project earned Mr Du the inaugural John Carmen prize for best oral presentation by a graduate student at the Medical Sciences Conference in Queenstown last month. The data he is gathering will give medical professionals a clear picture of the stomach's func- tion. It is also proving useful to medical companies that want to monitor the results of their pacemaker-type devices that stimu- late the stomach. It's not the first time his work has been recognised. In 2009 Mr Du won the top student award at the IEEE Engineering in Medicine and Biology conference in Minneapolis. The 25-year-old says many people do not realise that there is electrical activity connected with the stomach. By monitoring that electrical activity and modelling the data on a computer, bioengineers like Mr Du can create a moving picture that shows a patient's stomach function. To collect the data a flexible strip covered in electrodes like the tech- nology used in computers is inserted into a patient's abdomen and placed over the stomach. We recruited volunteers who were having surgery on other organs and asked them if we could monitor their stomach while their abdominal cavity was open.'' The electrode strip was left on each patient's stomach for 10 minutes to record electrical activity and then removed. We were only able to get 10 minutes on each patient because you can't leave people under anaes- thesia for too long,'' Mr Du says. Mr Du is writing up his thesis on electrical activity of the stomach and hopes to finish it in March.
