To explore the effect of standardized sequential nutrition support in the postoperative treatment of elderly patients with colorectal cancer.

From January 2014 to September 2018, 123 elderly patients with colorectal cancer admitted to the Affiliated People's Hospital of Nanchagn Universiy were divided into group A (62 cases) and group B (61 cases). The group A received standardized parenteral and enteral sequential nutritional support treatment, while the group B received conventional parenteral nutrition after operation, then convert to a regular diet. To compare the nutrition related indicators, postoperative recovery, and related complications between the two groups. T test was used to compare the measurement data between the two groups, and χ² test was used to compare the count data.

On the third day after operation, the level of prealbumin in group A was significantly lower than that in group B (t=2.670, P<0.01); on the seventh day after operation, the level of prealbumin and albumin in group A was significantly higher than that in group B (t=2.344, 2.677, P<0.05 or P<0.01). The time of anal exhaust/defecation in group A was significantly shorter than that in group B (t=2.113, P<0.05). There was no significant difference in the incidence of postoperative nutritional support complications between the two groups (t=2.736, P>0.05).

Standardized sequential nutritional support therapy for elderly patients with colorectal cancer can effectively improve postoperative nutritional status and enhance postoperative recovery of gastrointestinal function.
