Summary

Sarcoma is a rare malignancy made up by several sub types that can occur throughout the body. Roughly speaking, the division into soft tissue sarcoma (STS) and skeletal sarcoma (SS) can be made. STS of the limbs and trunk are primarily treated by surgical removal of the tumour and a margin of surrounding healthy tissue. Since size, depth and locale of tumours vary widely, surgery is seldom standardised. Both STS and SS commonly result in large resections, leaving tissue defects that are prone to local complications such as seroma formation, wound dehiscence and infection. A wound complication following surgery can be considered minor if it does not call for additional surgery, i.e. seroma formation, a superficial infection or delayed wound closure that can be helped by oral antibiotics or wound care. A major wound complication is one that requires surgical treatment like debridement surgery, secondary suture of a ruptured wound or flap-reconstruction. It is known that some tumour related factors increase the risk of wound complications, e.g. certain anatomical areas such as the inner thigh, large size and higher grade of the tumour. Other patient related factors known to influence the risk of complication are smoking, malnutrition and diabetes. There is some research on orthopaedic patients looking at intraoperative factors that could affect risk of infection. Time in surgery, prophylactic antibiotics and bleeding have all been shown to influence outcome. Enhanced Recovery After Surgery (ERAS) is a project implemented in other fields of surgery. It is a complete take on the risk factors for complications surrounding a patient and their surgery, as well as recovery afterwards. Some patient-related (intrinsic) risk factors associated with complications, such as obesity and alcohol abuse, take time to change. In other cases, even a short duration of for example smoke-cessation, correction of anaemia or better nutrition could have an effect on results. Intraoperative environmental (extrinsic) adjustments like surgical haemostasis and administration of Tranexamic acid are known to reduce risk of haematoma formation. This in turn reduces both the need for transfusion and the risk of infection. In other areas, multimodal anaesthesia and analgesia have been shown to decrease use of opioids while still offering sufficient pain relief. This leads to reduced postoperative nausea and further promotes early postoperative mobilisation. The thought behind a structured program addressing risk factors before, during and after surgery being that the collective risk reduction will big enough to be measurable where individual efforts might not be. Since sarcoma surgery is burdened by postoperative complications, every possibility to affect this should be explored.
