The PillBot System is an endoscopic capsule imaging system intended for visualization of the stomach. In contrast to currently used passive capsule endoscopy systems, and FDA cleared active magnetic system, the PillBot System uses active, motorized propulsion technology to facilitate the navigation and positioning of the capsule within the stomach anatomy for imaging of the gastric mucosa by an operator
Endoscopy is the diagnostic modality for most gastroduodenal diseases. During endoscopy mucus and foam may actually interfere with the visibility of the stomach mucosa. So the mixture of mucolytic ( N-acetyl cysteine) and anti-foaming agents ( simethicone) agents may disperse the bubbles and mucus in the stomach and enhance gastric visibility. This unique combination drink given 20-30 minutes prior to endoscopy is absolutely safe. There are previous studies from India, which was retrospective study. So, we have planned to conduct this randomized controlled trial on this issue. Adult patients undergoing diagnostic endoscopy will be randomized and one group (100 patients) will be given the combination drink whereas another group 9100 patients) will undergo an endoscopy after overnight fasting only, as a placebo drink may actually hamper the endoscopic visibility. Our primary outcome, gastric visibility will be assessed using a standard visibility scoring system.
The newly developed linked color imaging (LCI) system (FUJIFILM Co.) creates clear and bright endoscopic images by using short-wavelength narrow-band laser light combined with white laser light on the basis of BLI technology. This system can obtain bright endoscopic images even at a distant view because LCI has more intense white light than the short-wavelength narrow-band laser light. Short-wavelength narrow-band laser light enhances the vessels on the mucosal surface and the patterns of the mucosa. Therefore, LCI may facilitate the detection of gastric mucosal lesions. Further studies are needed to confirm the clinical utility of LCI.
The Investigators institution has used a meal consisting of mashed potato, peas and Beanfeast (soya mince) for gastric emptying studies for a number of decades. Validation of the study method was purportedly performed when the study was first implemented at the hospital, however no historical data has been found. The current normal ranges are also unsubstantiated. There is scientific justification for this research because in vivo studies are instrumental to the validation of a new procedure. There is a need for a meal preparation that is palatable and meets dietary requirements (vegetarian, gluten free e.t.c.) of patients as the diagnosis depends on ingestion of the radiolabelled meal. In addition, reliable normal ranges will ensure that the clinical diagnosis is accurate. Scientific justification extends beyond the local department as publishing the data acquired will allow other hospitals to adopt the same test meals and normal ranges, leading to standardisation of the clinical protocol employed across the UK. Since the investigators institution are recognised as the leading Nuclear Medicine GI centre in the UK and have previously carried out audits and in vitro testing in the area of gastric emptying, it seems fit that they should lead the national change in protocol. The proposed study will involve recruitment of healthy volunteers who will eat a meal containing 10MBq of a radioactive tracer. They will be subsequently scanned using a gamma camera with imaging lasting no more than 3 hours in total. Approximately 40 healthy volunteers (18-70 years old, no history of gastrointestinal problems or other serious health issues e.g. diabetes and pregnant women are excluded) will be recruited and the studies will be conducted on site i.e. within the Nuclear Medicine department at City hospital.
