Eight adult patients with visceral Chagas' disease were studied twice within an interval of 64 months. In each case the esophagus was evaluated radiologically and manometrically. None of the patients had esophageal symptoms and no significant change in resting gastroesophageal sphincter pressure was observed during the study. However in 3 patients incomplete sphincteric relaxation was noted. Normal progressive contractions did not change. The importance of these findings are discussed.
八名患有内脏型恰加斯病的成年患者在64个月的间隔内接受了两次研究。对每例患者均进行了食管放射学和测压评估。所有患者均无食管症状，且在研究期间未观察到静息时胃食管括约肌压力有显著变化。然而，有3例患者出现了括约肌不完全松弛。正常的进行性收缩未改变。本文讨论了这些发现的重要性。
