[Changtong oral liquid for prevention of postoperative intestinal adhesion: an experimental study]

Abstract

Objective: To observe the effect Changtong oral liquid (CTOL), a traditional Chinese drug preparation, on the prevention of postoperative intestinal adhesion.

Methods: Fifty-four male SD rats were randomly divided into 6 equal groups, namely the normal control, model control, Simo decoction (SMD, another traditional Chinese drug preparation), and CTOL groups, and CTOL group included three subgroups treated at low, moderate and high doses. Except for those in the normal control group, all the other rats were subjected to operation with Ellis' method for establishing intestinal adhesion models. After the operation, the rats in the normal control and model groups received intragastric administration of distilled water (10 ml/kg), SMD group received SMD administration in similar manner at the dose of 10 ml/kg, and the three CTOL groups had CTOL at the doses of 4.3, 8.6 and 17.2 g/kg, respectively. On day 7 after surgery, blood sample were taken from all the rats to determine the white blood cell (WBC) count and fibrinogen (FIB) concentrations, and the intestinal adhesion was graded.

Results and conclusion: CTOL evidently reduced the severity of postoperative adhesion and decreased WBC count and plasma FIB level, suggesting the efficacy of CTOL in inhibiting the formation of postoperative intestinal adhesion.
