Microwave coagulation using HS1 InstrumentDevice
Microwave therapy at 5.8 GHz
| Study group | Role | What they receive |
|---|---|---|
| patients receiving microwave therapy using the HS1 Instrument | Experimental | Not described Receives: Device: Microwave coagulation using HS1 Instrument |
What is being measured
The primary outcome is the main question the study is designed to answer.
Effective coagulation of of actual or potential non-variceal bleeding in the upper Gastrointestinal (GI) tract.
Primary haemostasis at day 0 using microwave coagulation of active bleeding or pre-coagulation of exposed vessels.
Measured: Perioperative
Secondary outcomes (3)
Identification and incidence of intra-procedural complications
Measured: Day 0
Identification and incidence of post-procedural complications
Measured: At 24-72 hours, 1 week and 4 weeks
Change in Glasgow-Blatchford score
The Glasgow-Blatchford score will be recorded prior to and after microwave intervention
Measured: Day 0 for initial screen and then 24-72 hours post-procedure for second score.
