Effect of skin incision (SI), laparotomy (LAP), or laparotomy plus mechanical stimulation of the small intestine and caecum (L+M) on intestinal transit in control rats (n = 9-10) and rats treated with metoclopramide (30 mg/kg; n = 9) or cisapride (1 mg/kg; n = 9-10). Results are expressed as cm migration of Evans blue and shown as mean (SEM). *Significantly different from the transit in control rats with the same operation (p⩽0.05); †significantly different from the transit in rats treated with metoclopramide with the same operation (p⩽0.05) (one way analysis of variance followed by the Bonferroni test).
