Ultrasonic cutting-coagulation devices (UCCD) are surgical instruments which use ultrasonic energy to cut through and coagulate tissue. An Ethicon version (trademarked "Harmonic Scalpel" and "Ultracision") is used in a variety of surgical procedures. Its surgical performance has been directly compared with that of electrically powered diathermy instruments in animal and clinical trials. LOTUS is a company based in Ashburton, Devon, which has developed a UCCD that works in a slightly different way to the Harmonic Scalpel. There are also bipolar feedback diathermy instruments which use electrical energy to seal blood vessels, such as LigaSure. The aim of this project is to obtain data to design a fully powered trial to answer the research question: do LOTUS and Ethicon UCCDs and LigaSure bipolar device reliably seal and divide blood vessels? The investigators will also be examining the degree of collateral tissue damage caused by each instrument.
- LOTUS UCCD, Ethicon Harmonic Scalpel and LigaSure are equivalent at sealing and dividing mesenteric blood vessels.
- LOTUS UCCD, Ethicon Harmonic Scalpel and LigaSure cause equal amount of collateral damage when sealing and dividing blood vessels.

Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.
