ABSTRACT
Objective To study the influence of laparoscopic gastric surgery on the gut barrier function (GBF).Methods There were 64 gastric cancer patients undergoing respectively laparoscopic radical procedures (32 cases) and open gastric surgery (32 cases).Blood was drawn on day one before surgery,day 1,day 3 and day 7 after the surgery for the measurement of plasma D-lacate and plasma diamine oxidase activity by using ultraviolet spectrophotometry.Results There was no statistical difference among demographic,clinicopathological characterastics between the two groups (P ＞ 0.05).The difference on the operative time,blood loss and the time starting to take food after the surgery was significant between the two groups,P ＜ 0.05.The differences of plasma D-lacate level and the diamine oxidase (DAO) on perioperatively respective all time points were not significant between the two groups,P ＞ 0.05.Conclusion Laparoscopic radical gastrectomy is comparable to open procedures in causing damage to patient's gut barrier functions.
