Table 2 Effect of preparation on transit time

Groups	Emptying gastric time (min)	Small bowel transit time (min)	P value
Group A (n=26)	53.1	216	NS

Group A: prepared by PEG or with SP, group B: prepared by erythromycin, group C: without any preparation, NS: non-significant.

Table 3 Effect of age on transit time

Groups	Emptying gastric time (min)			Small bowel transit time (min)
	Age (yr)			Age (yr)
	17 – 40	41 – 60	> 60	17 – 40	41 – 60	> 60
Group A (n=26)	16.8	46.5	163.7a	234.0	178.1	315.5
