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

Table 1

Distribution of cases according to study groups and intensity of myositis in esophagus and colon with or without mega.

	Esophagus				Colon
Miosytis	Without mega		With mega		Without mega		With mega
	𝑛	%	𝑛	%	𝑛	%	𝑛	%
Present	9	47	18	90	4	16	19	76
Mild	4	21	6	30	4	16	7	28

Fisher's exact test to compare the presence or absence of myositis: esophagus × colon 𝑃=0.0033, esophagus without mega × megaesophagus 𝑃=0.0057; colon without mega × megacolon 𝑃<0.0001; without megaesophagus × without megacolon 𝑃=0.0044; megaesophagus × megacolon 𝑃=0.2692.
