This two-day course will review the principles of oncological surgery with an engaging combination of seminars and practical procedures. Day 1 will introduce the language of oncological surgery and consider the appropriate application of surgery depending on tumour type, location and animal / owner factors. Biopsy and surgical treatment of common abdominal visceral masses will be practiced. Day 2 will focus on reconstruction following excision of superficial masses, considering the core principles of skin flap procedures to maximise the chance of a successful outcome, with the inclusion of challenging locations on the head and distal limb. Techniques to simplify reconstruction and reduce complications following surgery will be emphasised and there will be the opportunity to practice more complex reconstructive procedures to help in these awkward locations.
