Filter by: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.
Rationale: The construction of esophageal anastomoses is associated with considerable risk at postoperative anastomotic leakage. Application of TachoSil®, a tissue sealant with human fibrinogen and thrombin, can improve strength of the esophageal anastomosis and potentially prevent anastomotic leakage. Objective: Evaluation of feasibility and safety of TachoSil® application on esophageal anastomoses. Study design: Non-randomized, non-blinded, single-center intervention study. Study population: Patients, 18-80 years old, undergoing an elective total gastrectomy with an esophago-jejunostomy or esophagectomy with a planned esophagogastric anastomosis will be enrolled. A total number of 15 patients will be included in the study. Intervention: Gastric or esophageal resection will be executed according to the common procedures used in the UMC Utrecht. After construction of the esophageal anastomosis, all enrolled participants will receive a TachoSil® patch, which will be applied on the esophageal anastomosis intra-operatively. Hence, TachoSil® is used as an add-on therapy. TachoSil® will be degraded enzymatically in a period of approximately 24 weeks after application. Main study parameters/endpoints: The primary endpoint is feasibility, which is assessed by evaluation of adherence of the patch. A time-action analysis of the application of the Tachosil patch will be performed. Nature and extent of the burden associated with participation: The burden for the patient is minimal. The total surgical procedure will be prolonged with 10-15 minutes. Postoperative care and outpatient visits do not differ from regular protocol. TachoSil® is approved and registered for supportive treatment in surgery for improvement of haemostasis and to promote tissue sealing by the European Commission.
This feasibility trial will evaluate the ability of the SuMO Tissue Access and Resection System (Apollo Endosurgery, Austin, Texas). The SuMO System utilizes balloons to create a submucosal pocket and electrosurgical cutting device to resect the mucosa. The SuMO elevates the tissue from the underlying muscularis using a balloon to distend the submucosa, similar to what is currently performed with injectable saline in a standard EMR. After dissection of the lesion, a separate cutting device will be utilized to resect the tissue by cutting around the border of the targeted tissue. If needed, a standard loop snare will be used to complete the mucosal resection.
