Abstract

Objectives Conventional bowel preparation for colonoscopy confines patient to clear liquid diet the day before and such non-nutritive dietary regimen often caused discomfort and hunger. The purpose of this study is to determine the feasibility of feeding patient with low-residue, lactose-free semi-elemental enteral formula (PEPTAMEN®) compare to conventional clear liquid diet during bowel preparation before colonoscopy.

Methods This was a randomised, endoscopist-blinded study. Patients were randomised into two groups, those receiving oral PEPTAMEN® and mechanical bowel preparation (A) and those receiving clear liquid while undergoing mechanical bowel preparation (B). Documentation was made with regard to the type of bowel cleansing agents used, completeness of the colonoscopy, cleanliness quality score, and hunger score.

Results A total of 97 patients were included in the study, A = 48 and B = 49. Eight patients, who were not compliant to the bowel-cleansing agent or had an incomplete colonoscopic examination, were excluded from the study. In terms of the overall cleanliness score, no statistical significant difference was seen (p = 0.25) between the two groups, A (fair or poor 37.5%, good or excellent 62.5%) and B (fair or poor 49%, good or excellent 51%) whereas the hunger score showed a significant difference (p = 0.016), A (no hunger 41.7%, slight hunger 12.5%, hungry 12.5%) and B (no hunger 24.5%, slight hunger 38.8%, hungry 36.7%).

Conclusions These data suggest that the addition of oral PEPTAMEN® as part of the bowel preparation regimen did not significantly alter the luminal cleanliness score during colonoscopy while alleviating hunger.

Resumo

Objetivo A preparação intestinal convencional para a colonoscopia confina o paciente à dieta líquida clara no dia anterior; esse regime dietético não nutritivo frequentemente causa desconforto e fome. O presente estudo teve como objetivo determinar a viabilidade de alimentar o paciente com fórmula enteral semielementar sem lactose e pobre em resíduos (PEPTAMEN®) em comparação com a dieta líquida clara convencional no preparo intestinal para colonoscopia.

Métodos Este foi um estudo randomizado no qual o endoscopista foi cego quanto ao tipo de preparo. Os pacientes foram randomizados em dois grupos: aqueles que receberam PEPTAMEN® oral e preparo intestinal mecânico (A) e aqueles que receberam dieta líquida clara e preparo intestinal mecânico (B). Os pacientes foram avaliados quanto ao tipo de agente de limpeza intestinal utilizado, a completude da colonoscopia, o escore de qualidade de limpeza e o escore de fome.

Resultados Um total de 97 pacientes foram incluídos no estudo, 48 no grupo A e 49 no grupo B. Oito pacientes foram excluídos por não aderirem ao agente de limpeza intestinal ou apresentarem um exame incompleto de colonoscopia. Quanto ao escore geral de limpeza, não se observou diferença estatisticamente significativa (p = 0,25) entre os grupos A (resultado regular ou ruim, 37,5%; bom ou excelente, 62,5%) e B (resultado regular ou ruim, 49%; bom ou excelente, 51%). Por outro lado, o escore de fome apresentou diferença significativa (p = 0,016) entre os grupos A (sem fome, 41,7%; fome leve, 12,5%; fome, 12,5%) e B (sem fome, 24,5%; fome leve, 38,8%; fome, 36,7%).

Conclusões Os dados sugerem que a adição de PEPTAMEN® oral como parte do regime de preparo intestinal não altera significativamente o escore de limpeza luminal durante a colonoscopia, mas alivia a fome.
