ASA-PS values of patients who are planned to be operated due to gastrointestinal tumor will be recorded, then SORT (The Surgical Outcome Risk Tool) values will be calculated from sortsurgery.com. Sarcopenia measurements will be made by the radiologist from the abdomen CT at the L-3 level.~The pathology results of the patients will be recorded. Morbidity and mortality rates will be recorded in the short and long term.
The ASA-PS, SORT and Sarcopenia scores of the patients who will undergo surgery for a gastrointestinal tumor will be recorded. Thus, the correlation between preoperative indices and mortality/morbidity will be evaluated.
