Distribution of cases according to the study groups and intensity of esophagus and colon ganglionitis.

	Esophagus				Colon

Fisher's exact test to compare the presence or absence of ganglionitis: esophagus × colon P < 0.0001; esophagus without mega × megaesophagus P = 0.3416; colon without mega × megacolon P = 0.0001; without megaesophagus × without megacolon P < 0.0001; megaesophagus × megacolon P = 0.0592.
