Objective:To investigate the clinical application of enternal nutrition support via jejunostomy catheter after esopha-geal carcinoma excision. Methods:The patients of the parenteral nutrition group (PNn group) received completely parenteral nutrition support. The patients of the external nutrition group (EN group) received total intravenous nutrition support on the first day after the sur-gery. And the nutritional targets and immunological function were timely examined at different points. Results:The time of postopera-tive exhaust, defecation and hospital stay were all shorter in EN group than in the PN group (P<0.05). The index of nutritional and im-mune function was better in en group than in pn group. Conclusion:The enteral nutrition can improve the nutritional status, and can maintain and promote the postoperative gastrointestinal function of the esophageal cancer patients.
