  • Research summary

    The most common clinical emergency in the upper gastrointestinal (GI) tract is an acute bleed. In the UK, approximately 85,000 cases per year with 4000 death annually (or 10%) require emergency medical attention due to an acute GI bleed. The cost to the NHS for treating acute upper GI bleeds is estimated at £155 million annually, over 60% (£93 million) is spent on hospital stay, 25% (£38.5 million) on endoscopy treatment and 8% (£12.6 million) on blood transfusions.

    The HS1 instrument received CE marking based on its equivalence (In accordance with MEDDEV 2.7/1 revision 4) to the Speedboat RS2 in the lower GI. When the clinical evaluation was reviewed in the context of the upper GI, BSI determined that more clinical data was required to support the use of the microwave energy at 5.8 GHz.

    The next stage is to perform a human clinical trial in 35 patients to demonstrate that 1) our device will effectively seal any bleeding blood vessel or ulcer in the GI tract 2) cause no harm to the patient either during or after the procedure.

    Patient who present at the Queen Elizabeth the Queen Mother (QEQM) Hospital, with GI bleeding will be recruited into the study. Patients will be initially treated using the HS1 device (two attempts will be made), in the unlikely event that the bleed can not be effectively sealed, Dr Tsiamoulos (Chief investigator) will switch to the standard clinical practice to complete the task. Patients will be monitored for 24-72 hours and any adverse events recorded. A follow up assessment will be conducted at 1 & 4 weeks post-surgery.
