Abstract:Objective To observe the effect of colostomy irrigation and oral administration of probiotics on the intestinal flora and the life quality of patients underwent colostomy. Methods Between January 2012 and January 2015, a total of 58 patients underwent abdominal perineal joint colorectal cancer radical operation (Miles operation) in our hospitals were selected and randomly divided into observation group (29 cases) and control group (29 cases). The control group used natural defecation, and the observation group used colostomy irrigation and oral administration of probiotics. Intestinal flora of patiens was fosted and counted at preoperative period, the first time of postoperative defecation, two weeks and one month after operation. At the time of two weeks and one months after the operation, the core quality of life scale questionnaires were measured and compared in both groups. Results At the time of two weeks and one month after operation, intestinal bacteria of the observation group was significantly greater than the control group (P < 0.05). The quality of life in the observation group was significantly better than the control group (P < 0.05). Conclusions After Miles operation, colostomy irrigation and oral administration of probiotics can improve intestinal micro-ecological environment and the quality of life of the colostomy patients.
