Effect of early enteral combined with parenteral nutrition in patients undergoing pancreaticoduodenectomy

AIM: To investigate the effect of early enteral nutrition (EEN) combined with parenteral nutritional support in patients undergoing pancreaticoduodenectomy (PD). METHODS: From January 2006, all patients were given EEN combined with parenteral nutrition (PN) (EEN/PN group, n = 107), while patients prior to this date were given total parenteral nutrition (TPN) (TPN group, n = 67). Venous blood samples were obtained for a nutrition-associated assessment and liver function tests on the day before surgery and 6 d after surgery. The assessment of clinical outcome was based on postoperative complications. Follow-up for infectious and noninfectious complications was carried out for 30 d after hospital discharge. Readmission within 30 d after discharge was also recorded. RESULTS: Compared with the TPN group, a significant decrease in prealbumin (PAB) (P = 0.023) was seen in the EEN/PN group. Total bilirubin (TB), direct bilirubin (DB) and lactate dehydrogenase (LDH) were significantly decreased on day 6 in the EEN/PN group (P = 0.006, 0.004 and 0.032, respectively). The rate of grade. complications, grade. complications and the length of postoperative hospital stay in the EEN/PN group were significantly decreased (P = 0.036, 0.028 and 0.021, respectively), and no hospital mortality was observed in our study. Compared with the TPN group (58.2%), the rate of infectious complications in the EEN/PN group (39.3%) was significantly decreased (P = 0.042). Eleven cases of delayed gastric emptying were noted in the TPN group, and 6 cases in the EEN/ PN group. The rate of delayed gastric emptying and hyperglycemia was significantly reduced in the EEN/PN group (P = 0.031 and P = 0.040, respectively). CONCLUSION: Early enteral combined with PN can greatly improve liver function, reduce infectious complications and delayed gastric emptying, and shorten postoperative hospital stay in patients undergoing PD.
