Jenny Myers is a Clinical Scientist Oesophageal Function, CALHN (Queen Elizabeth Hospital &Royal Adelaide Hospital) and a Senior Lecturer and member of the research team in the University of Adelaide Department of Surgery. Her clinical and research interests are in the area of upper gastrointestinal motility with specific interests in motility disorders, gastro-oesophageal reflux and upper GI surgery, including fundoplication cardiomyotomy and bariatric surgery. Jenny completed a higher degree (PhD) evaluating factors that contribute to increased risk of troublesome dysphagia after anti-reflux surgery. Expertise in high resolution manometry, intra-luminal impedance and ambulatory reflux monitoring.
Oesophageal Function in Health and Disease
Upper GI Research Group
The overarching aim of my clinical research is to develop scientific measures of upper GI function and oesophageal function that lead to better understanding of symptoms for improved treatment outcomes.
Our aims are to:
- Advance physiological measurements that better inform management of Upper GI diseases, including
- Oesophageal motility disorders
- Gastro-oesophageal reflux disease (GORD)
- Laparoscopic surgery, including fundoplication, cardiomyotomy, bariatric procedures
Recent discoveries include:
- Exploration of dysphagia after fundoplication revealed
- 'Oesophageal ileus’ contributes to dysphagia in the early period after fundoplication
- Sub-optimal relationship between swallow pressure and bolus flow increases dysphagia risk
- Asymmetrical oesophago-gastric junction pressure and troublesome dysphagia after antirelfux surgery may relate to hiatal repair
The current research programs are:
- Examining the relationship between luminal diameter and flow through the oesophago-gastric junction, with regard to the symptom of dysphagia after fundoplication;
- Incidence of bile reflux after bariatric surgery, such as sleeve gastrectomy and gastric bypass surgery;
- High resolution manometry with intraluminal impedance in patients with dysphagia.
