Filter by:This study will compare gastrointestinal transit time measured by the SmartPill and the Atmo gas capsule in patients with gastrointestinal motility disorders. Both of these devices allow gastrointestinal transit time to be measured, however the SmartPill senses pH changes whereas the Atmo Capsule measures gas profiles. A total of 60 participants (30 diagnosed with gastroparesis, 30 with slow transit constipation) will attend Macarthur Clinical School at Western Sydney University after an overnight fast. Participants will consume a standardised meal before ingesting the SmartPill and Atmo Capsule. Each participant will carry a data receiver until passage of the capsules. Anatomical landmarks will be defined by pH changes (SmartPill) or oxygen profiles (Atmo Capsule). Statistical analysis will be performed via linear regression and degrees of agreement for measurements between the two devices. Primary end-points will be the agreement between gastric emptying, small intestinal and colonic transit times generated by the devices.
The current diagnostic process of colonic motility disorders often takes a long time and involves multiple invasive, painful and/or unnecessary diagnostic procedures. To improve this diagnostic process, the potential of Electro-Entero-Graphy (EEnG) is investigated. During the EEnG procedure, several surface electrodes are positioned (under ultrasound guidance) on the abdomen so that electrical activity originating in the colon can be measured. Measurements will be performed after a period of fasting (when the colon is 'silent') and just after a meal (when the colon is moving) in both participants suffering from colonic motility disorders and healthy controls. It is hypothesized that these measurements are an indication of colonic motility and can be used as a diagnostic tool for colonic motility disorders. It is also hypothesized that this EEnG procedure is not more burdensome than the Gold Standard procedures for diagnosing colonic motility disorders. This will be assessed using questionnaires.
Study the recurrence rate of constipation after laparoscopic total colectomy with high resection or low resection of rectum
Capsule endoscopy is a non-invasive way to examine the small bowel, but its yield is limited by the battery life. In 20% of cases, the recording stops before the entire length of small bowel is examined. Capsule transit speed is dependent on bowel motility. When we eat, the brain sends signal to the bowel to speed up motility. In this study the investigators wish to determine if chewing bacon (sham feeding) can trick the brain to speed up bowel motility and improve the rate of complete small bowel examination.
