Foram utilizados os testes Kruskal-Wallis e qui-quadrado para as análises estatísticas. Os pacientes responderam a um questionário referente ao sabor da solução ingerida e efeitos colaterais. Os exames foram analisados quanto ao grau de distensão intestinal e distinção da parede intestinal por dois examinadores em consenso. MATERIAIS E MÉTODOS: Estudo prospectivo, randomizado e duplo-cego em 30 pacientes submetidos a tomografia computadorizada de abdome e pelve com administração de contraste oral neutro, divididos em três grupos: leite, água e polietilenoglicol.
OBJETIVO: O objetivo deste estudo foi avaliar o desempenho de contrastes orais neutros, comparando a capacidade de distensão intestinal, a distinção da parede intestinal, a aceitação e os efeitos colaterais. Preparation with polyethylene glycol resulted in the best bowel distention, but it presented the worst taste and highest incidence of diarrhea as reported by patients.ĬONCLUSION: Bowel preparation with oral polyethylene glycol results in higher degree of bowel distention than with water or milk, but presents worst acceptance related to its taste and frequency of diarrhea as a side effect. RESULTS: Among 40 studied intestinal segments, appropriate bowel distension (intestinal loop diameter > 2 cm) was observed in 14 segments (35%) in the milk group, 10 segments (25%) in the water group and 23 segments (57%) in the polyethylene glycol group ( p = 0.01). Kruskal-Wallis and chi-square tests were employed for statistical analysis. The patients responded to a questionnaire regarding the taste of the ingested solution and on their side effects. The images were consensually analyzed by two observers, considering the degree of bowel distention and intestinal wall distinction. MATERIALS AND METHODS: Prospective, randomized, and double-blinded study involving 30 patients who underwent computed tomography of abdomen and pelvis with administration of neutral oral contrast agents, divided into three groups according the contrast agent type: milk, water, and polyethylene glycol. OBJECTIVE: The purpose of this study was to assess the performance of neutral oral contrast agents, comparing intestinal distention, distinction of intestinal wall, acceptance and side effects.
