The requirement for diagnostic surgical operations of gastrointestinal systemdiseases significantly decreases with the help of proper diagnostic tools. Thesemodalities are also beneficial for identifying postoperative complications, allowing usto diagnose them in earlier stages, and increasing the postoperative survival rates.Biomarkers are considered an integral part of diagnostic examinations.
