Dietary fibre and probiotics may play a role in the management of diverticular disease. In adults with asymptomatic (AS) or symptomatic uncomplicated diverticular disease (SUDD), this systematic review aims to synthesize evidence on the efficacy of dietary fibre modifications, with or without the use of probiotics, on gastrointestinal function, symptoms, and diverticulitis incidence. Five electronic databases were searched for studies until December 2018. The body of evidence was appraised using the Cochrane Risk of Bias tool and GRADE. Nine studies were included with mean sample ages ranging from 57 to 70 years, and three meta-analyses were performed. Only one study, with high risk of bias, measured the effect of dietary fibre on diverticulitis incidence. Dietary fibre supplementation was found to improve stool weight (MD: 42g/day, P<0.00001; GRADE level of evidence: low), but had no significant effect on gastrointestinal symptoms (SMD:-0.13, P=0.16; GRADE level of evidence: low) or stool transit time (MD:-3.70, P=0.32 GRADE level of evidence: low). There was "very low" confidence for the body of evidence supporting symbiotics for AS or SUDD. A high dietary fibre intake, in line with dietary guidelines, may improve gastrointestinal function and is recommended in patients with AS or SUDD. Dietary fibre supplementation should be considered on an individualised basis to improve bowel function, while the recommendation for symbiotic supplements requires further welldesigned research. Future studies should also measure impact on the incidence of diverticulitis.
Corrupted diet-disease knowledge and fear of food trigger suffering in patients with a history of acute diverticulitis An interpretative phenomenological analysis Malnutrition To understand the impact of dietary restrictions for the management of acute diverticulitis on patient experience. Methods Four semi-structured in-depth face-to-face interviews were conducted with adult patients admitted to a public hospital in South East Queensland, Australia, for acute, uncomplicated diverticulitis treatment. All participants had experienced acute diverticulitis previously, with the first episode ranging from 6months to 30-years ago. Interviews were analyzed following the interpretative phenomenological analysis (IPA) framework.
Influence of inpatient dietary prescription on recovery from and reoccurrence of acute, uncomplicated diverticulitis A 3-year prospective cohort study This study aims to assess the impact of restricted versus liberalized inpatient dietary prescription on recovery from and reoccurrence of acute, uncomplicated diverticulitis. The methods Prospective observational study of adult patients admitted to two metropolitan hospitals in Queensland, Australia, from 2016-2019. Hierarchical multiple linear regression was used to determine the impact of restricted versus liberalized diets on hospital length of stay (a proxy for recovery). Binomial logistic regression was used to determine the impact of restricted versus liberalized diets on 30-day and 6-month reoccurrence of diverticulitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
