Sarcopenia is the loss of muscle mass that occurs usually with aging, but it may have multiple contributing factors, especially related to chronic diseases such as colorectal cancer.~When present, sarcopenia is predictive of poor post-operative course. The identification of sarcopenia needs either the identification of low muscle strength, low muscle quantity/quality, or finally a low physical performance.~Multiple clinical, biological or radiological tools were proposed. Our purpose is to compare the post-operative outcome of sarcopenic and non sarcopenic patients using a simple, available, reproducible and rapid radiological method, which will help the healthcare professionals to rapidly identify high risk patients for possible complicated and long post-operative course allowing them to take appropriate perioperative measures to reduce the risks.
The purpose of this study is to compare the post-operative course in patients suffering from sarcopenia who had colorectal surgery for cancer. Our primary outcome is the comparaison of the length of hospital stay in sarcopenic and non sarcopenic patients.
