ObjectiveTo investigate the effects of enteral nutrition support via nasal-jejunal tube on gastrointestinal protection and nutritional status improvement in patients with severe acute pancreatitis. MethodsThe data of 98 patients with severe acute pancreatitis were retrospectively analyzed, and they were divided into two groups according to nutritional support method, with 49 cases in each group. The control group received parenteral nutrition support, and the observation group received enteral nutrition support via nasal-jejunal tube. The gastrointestinal function and nutritional status before and after the treatment, as well as the incidence of complications during hospitalization, were compared between the two groups. ResultsOn the 7th day after stopping nutritional support, the serum diamine oxidase and D-lactic acid levels in the observation group were lower than those in the control group, and the time for diarrhea and abdominal distension release, nausea and vomiting release, bowel sounds recovery, anal exhaust recovery, and oral feeding recovery were shorter than those in the control group, while the serum albumin, prealbumin and transferrin levels were higher than those in the control group (all P＜0.05). During hospitalization, the incidence of complications in the observation group (4.08%) was lower than that in the control group (16.33%) (P＜0.05). ConclusionEnteral nutrition support via nasal-jejunal tube can effectively protect the gastrointestinal tract of patients with severe acute pancreatitis, promote the early recovery of gastrointestinal function, further improve their nutritional status and reduce the incidence of complications.
