Abstract
To compare the impact of traditional and fast bowel preparation on the changes of gut flora in the patients following colorectal resection. Sixty patients undergoing colorectal resection from March 2010 to March 2011 in the Nanfang Hospital were randomly divided into the control group(n=27, 3 days of bowel preparation) and the experimental group(n=33, 1 day of bowel preparation). Fresh feces were collected before bowel preparation and on the first defecation after surgery. The postoperative changes in gut flora and septic complications were observed. Gut flora disturbance was found in both groups. The postoperative population of Bifidobacterium and Lactobacillus decreased significantly(P<0.05), and the decrease was more significant in the experimental group compared to the control group(P<0.05), while E.coli and Staphylococcus were much higher than the preoperative level(P<0.05), which was more significant in the control group. The incidence of postoperative infection was 9.1%(3/33) in the experimental group, which was significantly lower than 29.6%(8/27) in the control group(P<0.05). Fast bowel preparation is effective in reducing gut flora disturbance and the incidence of postoperative infection.
