Comparative study of early enteral nutrition between laparoscopic and open distal gastrectomy / 肠外与肠内营养

ABSTRACT

Objective:To investigate the effect of early postoperative enteral nutrition (EEN) on laparoscopic and open radical gastrectomy.Methods:From January 2015 to December 2016,68 patients with gastric cancer admited in Anqing Hospital,Anhui Medical University,were randomized into laparoscopic group (33 cases) and open group (35 cases).The following parameters were collected(1) Surgical outcomes and complications;(2) EEN tolerance;(3) postoperative nutritional status;(4) starting time of postoperative chemotherapy.Results:There was no significant difference between groups in terms of operation time,number of lymph node,postoperative complications such as anastomotic fistula,pulmonary infection,incision infection (P ＞ 0.05);whereas the intraoperative blood loss was significantly less in laparoscopic group (P ＜ 0.01).(2) EEN tolerancePostoperative discomforts,such as abdominal distension,diarrhea and other symptoms occurred significantly less in laparoscopic group (P ＜ 0.01),and time for TEN is significantly shorter (P ＜ 0.01).(3) Postoperative nutritional statusOn the 7th day after operation,the nutrition status of the laparoscopic group improved earlier.There was significant difference regarding the detected blood level of prealbumin and C-reactive protein between the two groups (P ＜ 0.01).On the 14th day after operation,the nutritional status of the laparoscopic group improved significantly.The body weight,the right upper arm muscle circumference and the albumin were significantly different between two groups (P ＜ 0.05).(4) The number of cases receiving chemotherapy in patients with advanced gastric cancer was significantly higher in laparotomy group than that with open distal gastrectomy.Conclusion:Laparoscopic surgery for gastric cancer reduces surgical trauma,and leads to better EEN tolerance and earlier achieved TEN,which is conducive to improving postoperative nutritional status,as well as providing good conditions for adjuvant chemotherapy.
