ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (P lt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (P lt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (P gt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.
