Research on Trypanosoma cruzi and Analysis of Inflammatory Infiltrate in Esophagus and Colon from Chronic Chagasic Patients with and without Mega

Table 2

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

	Esophagus				Colon
Ganglionitis	Without mega		With mega		Without mega		With mega
	𝑛	%	𝑛	%	𝑛	%	𝑛	%
Present	16	84	19	95	4	16	18	72
Mild	9	47	4	20	4	16	7	28

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.
