          Abstract

          OBJECTIVE: The aim of our study was to analyze whether the presence of content in the rectum influences the anorectal manometry examination results in chronically constipated patients. METHODS: We evaluated 38 chronically constipated patients, 36 women and 2 men, with an average age of 53.55 years of age, all with a score above 10 on the Agachan Constipation Scoring System. All the patients underwent rectal preparation and then had the anorectal manometry examination without rectal content and after 5 min had it with a rectal balloon inflated with 200 ml of air in the rectum. STATISTICAL ANALYSIS: The statistical parametric paired-t test was applied in order to verify the difference in response between the groups after an intervention, adopting a significant level of 5% (p < 0.05). RESULTS: The anal pressure was analyzed from the standard anal manometry examination and we found a statistically significant influence on the manometric results for the patients' average resting pressures, absolute average contractions, average contractions, evacuations, and sustained contractions in the functional anal canals. CONCLUSION: The presence of rectal content influences the manometric values of average resting pressure, average absolute contraction, average contraction, evacuation, and average sustained contractions in the functional anal canal in the group of chronically constipated patients.

          OBJETIVO: O objetivo deste estudo foi analisar se a presença de conteúdo no reto influencia os resultados do exame de manometria anorretal em pacientes cronicamente constipados. MÉTODOS: Foram avaliados 38 pacientes cronicamente constipados, 36 mulheres e dois homens, com média de 53,55 anos de idade, todos com pontuação acima de 10 no Agachan Constipation Scoring System. Todos os pacientes foram submetidos a preparo retal e, em seguida, passaram por um exame de manometria anorretal sem conteúdo retal e, depois de transcorridos cinco minutos, um novo exame foi realizado, agora com um balão retal inflado com 200 ml de ar no reto. ANÁLISE ESTATÍSTICA: Na análise estatística, foi aplicado o teste t paramétrico, com a finalidade de verificar a diferença, em termos de resposta, entre os grupos após uma intervenção. Para tanto, foi adotado um nível de significância de 5% (P <0,05). RESULTADOS: A pressão anal foi analisada com base no exame de manometria anal de rotina; em nossos pacientes, foi observada influência estatisticamente significativa nos resultados manométricos para as pressões médias em repouso, contrações médias absolutas, contrações médias, evacuações e contrações sustentadas nos canais anais funcionais. CONCLUSÃO: A presença de conteúdo retal influencia os valores manométricos da pressão média em repouso, contração absoluta média, contração média, evacuação, e contrações sustentadas médias no canal anal funcional no grupo de pacientes cronicamente constipados.

          Intestinal and anorectal motility and functional disorders.

          Motility and functional disorders of the small intestine, the colon and the anorectum can induce or contribute to symptoms such as diarrhoea, constipation and abdominal pain and may impair nutrient absorption in severe cases. Acute affections of intestinal functions e.g. during gastrointestinal infections usually need no functional diagnostics but resolve spontaneously or with adequate therapy of the underlying disease. By contrast, chronic disturbances of small intestinal, colonic and anorectal motility and/or sensitivity are subject to gastrointestinal function tests. The role of these tests for diagnosis and therapeutic handling of severe intestinal dysmotility/chronic intestinal pseudo-obstruction, severe constipation, diarrhoea, fecal incontinence and irritable bowel syndrome will be discussed in this review that mainly focuses on adults.
