MEGACÓLON PSICOGÊNICO EM PACIENTE PORTADOR DO TRANSTORNO DO ESPECTRO AUTISTA: UM RELATO DE CASO

Introduction: Psychogenic megacolon (PM) is a rare dysfunction usually found during childhood. This condition is characterized as an abnormal and irreversible dilation of the intestinal colon of psychogenic etiology, that is, such motility disorder is linked to some emotional disorder. A full understanding of this disorder is still a long way off due to its scarce description in the medical literature, however, authors such as Liu et al (2019) define it as a persistent dilation of the colon in the absence of any underlying organic or physiological causes, highlighting its diagnosis as purely eliminatory due to its symptomatic similarity with congenital megacolon (Hirschprung's disease). Objectives: The following case report aims at a retrospective and cross-sectional study, arising from the analysis of the patient's medical records, in order to lay scientific foundations for future research addressing the thematic axis of MP in conjunction with the development of new, more effective therapeutic proposals for the disease. Methods: The data provided in this study were obtained from the active collection of information from the patient's medical record, analyzed in line with others extracted from an interview with the person responsible, however, a literature review was carried out using data platforms as sources of good origin such as Scielo Platform, Google Scholar and PubMed. Results: The case describes a 3-year-old male patient, diagnosed with autism spectrum disorder (ASD) and with a history of previous hospitalizations related to urinary tract infection (UTI) and médium acute otitis (MAO). In the current history, the patient was admitted due to an acute infectious condition unrelated to MP, however, a distended and painless abdomen was found with increased peristalsis with decreased frequency of bowel movements and the presence of a large fecal cake. via ultrasound, with the diagnosis of megacolon, the clinic was related to the diagnosis of ASD and the patient's difficulty in adapting to the hospital environment, making the hypothesis of MP very likely. Conclusion: The report above describes a highly suggestive picture for MP, while this study seeks to raise the hypothesis of its correlation with ASD, while this neurodevelopmental disorder can influence the bowel habits of those patients historically included within the age group conducive to the manifestation of this disease.
