Objective: To build the application clinical patterns of parenteral nutrition support in acute intestinal obstruction postoperative recovery. Methods: Selected 56 patients with surgical treatment of acute intestinal obstruction from January 2015 to December 2015 as study group, in which patients received parenteral nutrition support treatment; 47 cases with surgical treatment of acute intestinal obstruction from January to December, 2014 was selected as control group, in which patients received enteral nutrition support treatment, analyzed the recovery of two groups with different way of nutritional support effect.
