**1. Introduction**

American trypanosomiasis ranks as the fourth most frequent disease-causing loss of productive years [1]. Also known as Chagas disease, this disease is a parasitic infection transmitted by hematophagous vectors [2] and is characterized by an acute period with general symptoms, which leads to a chronic phase and the development of complications at different levels of the infected organism. The reports, made by the World Health Organization (WHO), mention that in the world there are between 16 and 18 million infected people which approximately only 1% receives an early diagnosis and full treatment, being the area with the highest incidence is in the Latin American area where this infection is considered endemic. Due to the public health implications and the high percentage of complications that it presents in chronic phases, the Pan-American organization and the World Health Organization consider this disease as the most serious parasitic infection in Latin America [1].

In addition to vector transmission, this infection can be spread vertically through infected women during pregnancy, leading to gestational disease with implications for uterine or neonatal development.

Among the major complications of the chronic stage of Chagas disease, it is the development of the so-called—mega syndromes, within which megaesophagus and Chagasic megacolon are more frequently included, which develop from alterations in the neurosensory system in the muscular layers of these organs. Both scenarios present significant complication rates that condition the loss of productive years, a decrease in the quality of life, and compromise life depending on the presentation of volvulations or eating disorders.

Although the development of complications associated with the chronic stages of Chagas diseases, such as intestinal volvulations [3] in megacolon, is relatively uncommon in Western countries, it is still considered the most severe complication [4], positioning itself as the third cause of lower intestinal obstruction in some countries, only below diverticular disease and colon cancer [1]; with respect to megaesophagus, complications can occur even in patients who are considered asymptomatic, who nevertheless present motor disorders of the esophagus that can lead to the development of neoplasms.
