Comparison of Electrocautery and Quantum Energy Surgical Devices in Experimental Partial Hepatectomies

The quantum energy surgical device (QESD) is a new medical instrument that uses kinetic energy to heat the atoms of argon gas to a high temperature and to apply them on tissues. Unlike other devices operating on the principle of argon plasma technology, the QESD can be used in tissue vaporisation, resection, coagulation and superficial sterilisation of tissues. This study aimed to compare the amount of bleeding, duration of liver incision, duration of the whole operation and histopathological changes occurring on the surface of the incision in partial hepatectomies performed by QESD and bipolar electrocautery. The study was carried out on 16 rabbits, and showed that the QESD caused less bleeding and made it possible to perform the operations in a shorter period of time. Histopathologic examination revealed that in both the groups of rabbits operated on either by QESD or bipolar electrocautery, various changes occurred on the surface of the incision due to thermal trauma. However, the former technique was superior to the latter in terms of the efficiency of haemostasis. Deneysel Parsiyel Hepatektomilerde Elektrokoter ve QESD (Quantum Energy Surgical Device) Cihazlar›n›n Karfl›laflt›r›lmas› Ozet: Yeni bir medikal enstruman olan QESD (Quantum energy surgical device, kuantum enerji operasyon cihaz›), kinetik enerji verilerek yuksek s›cakl›¤a c›kar›lm›fl olan argon gaz› atomlar›n›n dokulara uygulanmas› prensibi uzerine tasarlanm›flt›r. Dier argon plasma teknolojisiyle cal›flan cihazlardan farkl› olan QESD ile doku buharlaflt›rma, rezeksiyon, koagulasyon ve dokular›n yuzeysel sterilizasyonu yap›labilmektedir. Bu cal›flmada QESD ve bipolar elektrokoter ile yap›lan parsiyel hepatektomilerde kanama miktar›, karacier ensizyon suresi, toplam operasyon suresi ve kesit yuzeyindeki histopatolojik deiflimler incelenmifltir. Toplam 16 tavflanda gerceklefltirilen bu deneysel cal›flma sonucunda, QESD ile yap›lan uygulamalarda kanaman›n cok daha az olduu ve operatif prosedurlerin daha k›sa surede tamamland›¤› saptanm›flt›r. Histopatolojik incelemelerde kesit yuzeylerinde her iki grupta termal travmaya iliflkin farkl› deifliklikler saptanmakla birlikte, hemostaz etkinlii yonunden QESD grubunun ustunlu¤u ortaya
