Objective  To study the effect of probiotics on the change of intestinal permeability and inflammatory reaction after surgery of colorectal cancer. Methods  Sixty patients who underwent colonic surgery were randomly divided into two groups: probiotic group and control group, with 30 cases in each group. Each group received nutritional support of the same nitrogen and calorie from day 3 to day 7 after operation. The patients in probiotic group were orally administrated probiotic (2 g/d) from the first day after surgery for 7 days. Every patient’s body temperature and heart rate were observed after operation, and white blood cell counts were observed before operation and on day 1, 5, 8 after operation. The levels of microbial DNA in whole blood and plasma D-lactate, and urine lactulose/mannito (L/M) ratio were measured before operation and on day 1 and day 8 after operation, respectively. In addition, the occurrence of postoperative systemic inflammatory response syndrome (SIRS) and complications of inflammation were closely observed. Results  The average heart rate in postoperative 5 days was significantly lower in probiotics group than that in control group (P<0.01). The duration of fever and the recovery time for white blood cell counts decreasing to normal were significantly less in probiotics group than those in control group (P<0.01) as well. There was no significant difference of positive rate of microbial DNA in peripheral blood on day 1 after operation between two groups. However, the number of patients that showed positive result of microbial DNA PCR test in probiotic group (1 case, 3.3%) was significantly less than that of control group (7 cases, 23.3%)on day 8 after operation (P<0.05). The level of plasma D-lactate in probiotic group 〔decreasing from (6.90±1.41) ng/ml on day 1 to (0.56±0.18) ng/ml on day 8〕 was also significantly lower than that in control group 〔decreasing from (6.63±1.29) ng/ml on day 1 to (0.95±0.83) ng/ml on day 8〕 on day 8 after operation (P<0.05). Urine L/M ratio increased from 0.053±0.019 on day 1 to 0.063±0.016 on day 8 after operation in control group; while in probiotic group, the ratio decreased from 0.047±0.012 on day 1 to 0.031±0.008 on day 8 after operation, and there was significantly statistical difference of the ratio between two groups on day 8 (P<0.01). There was no significant difference of the occurrence rate of SIRS and complications of inflammation between two groups (P gt;0.05). Conclusion  Probiotics can decrease intestinal permeability and maintain the intestinal barrier function after operation. It may be helpful for the recovery of patients with early inflammatory response after surgery of colorectal cancer.
