Abstract: Objective To investigate the value of guidance and clinical significance of enteral nutritional support therapy using a joint of nutritional risk screening 2002 (NRS2002) and a screening tool for controlling nutritional status (CONUT) after radical resection of colorectal cancer.Methods The clinical data of 180 patients who underwent radical resection of colorectal cancer at the Tumor Hospital of Xinjiang Medical University between June 2012 and June 2014 were retrospectively analyzed.Seventy patients with scores of NRS 2002 ≥ 3 were allocated into the A group including 40 with enteral nutritional support therapy in the A1 group and 30 without enteral nutritional support therapy in the A2 group, 60 patients with scores of NRS 2002 ＜ 3 and negative CONUT was allocated into the B group including 30 with enteral nutritional support therapy in the B1 group and 30 without enteral nutritional support therapy in the B2 group, 50 patients with scores of NRS 2002 ＜ 3 and positive CONUT was allocated into the C group including 25 with enteral nutritional support therapy in the Cl group and 25 without enteral nutritional support therapy in the C2 group.The nutritional status of patients was evaluated using a joint of NRS 2002 and CONUT.There was nutritional risk in patients with scores of NRS 2002≥3 or scores of NRS 2002 ＜ 3 and positive CONUT and no nutritional risk in patients with scores of NRS 2002 ＜ 3 and negative CONUT.Patients and their families would choose whether or not to undergo enteral nutritional support therapy after the risks being informed.Enteral nutritional support therapy included tube feeding enteral nutrition or oral nutriments with calories ≥41.84 k J/(kg · d) for more than 3 days.Observed indicators: (l)Nutritional indicators included fasting serum albumin (Alb), prealbumin and transferrin before operation, at postoperative day 1 and day 7.(2)Postoperative recovery included time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay.Measurement data with normal distribution were presented as x ± s, comparison among groups was analyzed using the t test and repeated measures ANOVA, and count data were analyzed using the chi-square test.Results Patients in A, B and C groups had good tolerance without abdominal pain, abdominal distension and diarrhea.Comparisons of nutritional indicators: the levels of fasting serum Alb, prealbumin and transferrin in the A1 group were (29 ±4)g/L, (0.25 ±0.06)g/L and (2.0 ±0.4)g/L before operation, (27 ±4)g/L, (0.19 ± 0.07) g/L, (1.7 ± 0.4) g/L at postoperative day 1 and (33 ± 5) g/L, (0.27 ± 0.05) g/L and (1.9 ± 0.3) g/L at postoperative day 7, respectively.The levels of fasting serum Alb, prealbumin and transferrin in the A2 group were (29 ±5)g/L, (0.24 ±0.04)g/L and(2.0 ±0.4)g/L before operation, (27 ±4) g/L, (0.18 ±0.05)g/L and (1.7 ± 0.4) g/L at postoperative day 1 and (26 ± 4) g/L, (0.16 ± 0.04) g/L and (1.8 ± 0.5) g/L at postoperative day 7, respectively.There were significant differences in the changing trends of the above 3 indicators between the 2 groups (F =3.256, 6.642, 7.152, P ＜0.05).The levels of fasting serum Alb, prealbumin and transferrin in the B1 group were (37 ± 4) g/L, (0.28 ± 0.05) g/L and (2.0 ± 0.3) g/L before operation, (36 ± 4) g/L, (0.21 ± 0.06) g/L and (1.7 ± 0.5) g/L at postoperative day 1 and (38 ± 4) g/L, (0.30 ± 0.05) g/L and (1.9 ± 0.5) g/L at postoperative day 7, respectively.The levels of fasting serum Alb, prealbumin and transferrin in the B2 group were (36 ±4)g/L, (0.28 ±0.06)g/L and (2.1 ±0.4)g/L before operation, (36 ±3)g/L,(0.23 ±0.04)g/L and (1.7 ±0.4)g/L at postoperative day 1 and (37 ±4)g/L, (0.22 ±0.07)g/L and (1.8 ± 0.5) g/L at postoperative day 7, respectively.There was no significant difference in the changing trends of the above 3 indicators between the 2 groups (F =1.562, 0.625, 2.223, P ＞ 0.05).The levels of fasting serum Alb,prealbumin and transferrin in the C1 group were (28 ± 4) g/L, (0.35 ± 0.06) g/L and (2.1 ± 0.4) g/L before operation, (26 ±4)g/L, (0.17 ± 0.07)g/L and (1.7 ± 0.4)g/L at postoperative day 1 and (34 ± 5)g/L,(0.35 ±0.05)g/L and (1.8 ± 0.3)g/L at postoperative day 7, respectively.The levels of fasting serum Alb,prealbumin and transferrin in the C2 group were(28 ± 5)g/L, (0.34 ± 0.04)g/L and (2.0 ± 0.4)g/L before operation, (26 ± 4) g/L, (0.16 ± 0.05) g/L and (1.7 ± 0.4) g/L at postoperative day 1 and (25 ± 4) g/L,(0.16 ±0.04) g/L and (1.8 ±0.5)g/L at postoperative day 7, respectively.There were significant differences in the changing trends of the above 3 indicators between the 2 groups (F =5.625, 4.225, 8.221, P ＜0.05).Postoperative recovery: time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.9 ± 0.5) days, (2.3 ± 0.5) days, (8.6 ± 1.2) days, (14.7 ± 1.1) days in the A1 group and (3.0 ± 0.5) days, (4.5 ± 0.6) days, (11.4 ± 2.2) days, (17.8 ± 1.3) days in the A2 group, respectively,with significant differences between the 2 groups (t =-0.644,-12.200,-8.710,-11.650, P ＜ 0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.2 ± 0.3)days, (3.2 ±0.7)days, (10.3 ± 1.4)days, (14.7 ±2.0)days in the B1 group and (1.5 ±0.5)days, (3.7 ± 0.6) days, (11.0 ± 1.2) days, (16.1 ± 1.5) days in the B2 group, respectively, with no significant difference between the 2 groups (t =-1.929,-1.033,-1.019,-1.171, P ＞0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.8 ± 0.7) days, (2.1 ± 0.5) days,(7.6±1.2)days, (13.9 ±1.2)days in the C1 group and (3.1 ±0.5)days, (4.5 ±0.7)days, (11.4±2.4)days,(17.6 ± 1.3) days in the C2 group, respectively, with significant differences between the 2 groups (t =-5.934,-10.950,-10.010,-11.700, P ＜ 0.05).Conclusions A joint application of NRS2002 and CONUT after radical resection of colorectal cancer is exact and feasible for evaluating nutritional status of patients and guiding enteral nutritional support therapy.Patients should select nutritional support therapy after operation if there is nutritional risk.The proper nutritional support therapy can improve the postoperative nutritional status of patients with colorectal cancer, enhance the postoperative recovery and reduce the duration of hospital stay.
