To explore the pathogenesis of anterior resection syndrome by magnetic resonance imaging rectal defecography

Table 1 Evaluation of three different methods in the experimental group 6 months after operation and 12 months after operation

	Six months after operation	Twelve months after operation	P value
LARS score (n = 34)	37.02 ± 4.91	32.58 ± 3.43	< 0.001
Defecation rate% (n = 34)	39.47 ± 0.15	35.53 ± 0.17	0.411
MRI-RC score (n = 34)	4.41 ± 2.40	4.82 ± 2.92	0.165

LARS: Low Anterior Resection Syndrome Score; MRI-RC: Magnetic resonance imaging-rectal compliance.
