BACKGROUND Radiofrequency ablation is a popular method of treating unresectable liver tumors but tumors greater than 3 cm in diameter have a much greater risk of local recurrence after treatment. Bimodal electric tissue ablation is a modified form of radiofrequency ablation that creates significantly larger ablations by the addition of extra direct current(More)
Radiofrequency ablation (RFA) is a method of treating non-resectable liver tumors by use of a high-frequency alternating electrical current. Concerns have been raised as the local recurrence rates following treatment have been reported to be as high as 47%. The size of the ablation is limited by charring of adjacent tissues. It is hypothesized that by(More)
OBJECTIVE Diverticular disease is common in our community. Most patients remain asymptomatic and the development of diverticular complications is rare. A common clinical observation is that patients presenting with complications of diverticular disease are obese. The aim of this study was to examine the relationship of obesity to the complications of(More)
BACKGROUND Bimodal electric tissue ablation is a novel variation to standard radiofrequency ablation that produces significantly larger ablations by the addition of a direct electrical current. The negative electrode is attached to the radiofrequency current and the positive electrode is placed nearby. It has been identified that an electrolytic injury can(More)
Numerous techniques are used to maintain intraoperative heart viability. The studies presented here evaluated heart function and metabolism after various periods of preservation up to 4 hours with intermittent warm and cold blood perfusion. Using a heterotopic heart model cooled to 10 degrees C and maintained for 1, 2, 3, and 4 hours, various preservation(More)
INTRODUCTION The role and timing of postoperative radiotherapy (PORT) in the management of retroperitoneal sarcoma (RPS) remains controversial. METHOD This is a retrospective cohort review of patients undergoing curative resection for RPS at a single institution between January 2011 and July 2016. Patient selection was through the South Australian Soft(More)
