To explore the value of PG-SGA score in predicting postoperative complications in patients with colon cancer.

The clinical data of 200 patients with colon cancer underwent surgical treatment from June 2014 to December 2018 were retrospectively analyzed. The preoperative nutritional status of all patients were evaluated with PG-SGA score. According to the nutritional risk, they were divided into normal nutrition group (PG-SGA score ≥ 4, 112 cases) and malnutrition group (PG-SGA score < 4, 88 cases). Statistical analysis were performed by using SPSS 19.0 software. Measurement data, such as perioperative indicators were expressed as (±s), and were examined by using independent t test. Count data such as incidence of postoperative complication rate and general data were examined by chi square test or Fisher exact probability method. A P value <0.05 was considered as statistically significant difference.

There was no significant difference between the two groups in terms of sex, age, lesion location, ASA score, differentiation, TNM stage, tumor size and pathological type (P>0.05). The duration of hospitalization and the cost of hospitalization of the patients in the normal nutrition group were significantly less than those in the malnutrition group respectively (P<0.05). The incidence of postoperative complications in the normal group was significantly lower than that in the malnutrition group (8.04% vs 32.95%, P<0.05).

The risk factors of postoperative complications in colon cancer patients with PG-SGA score < 4 are high, which deserves clinical attention.
