[Relationship between Surgical Site Infection(SSI)Incidence and Prognosis in Colorectal Cancer Surgery].

We examined the relationship between risk factors for surgical site infections(SSIs)and prognosis in 440 patients who underwent colon cancer surgery. We evaluated factors related to SSIs(GradeB II)and compared survival rates by stage. SSIs were observed in 36 patients. An increased SSI incidence was associated with pulmonary dysfunction, mGPS=2, CONUT≥2, PNI≤40, NLR>4.3, location(rectum), depth of tumor invasion(Bsubserosa, SS), lymph node metastasis, laparotomy, resection of other organs, colostomy, blood loss(large), and operative time(long). Survival rates were lower in Stage II/III patients with SSIs. Preoperative risk judgment is important in colorectal cancer surgery.
