Abstract

Background: Due to a lack of evidence regarding the dietary
management of acute uncomplicated diverticulitis, practice
varies for discharge nutrition recommendations, and may
include modified dietary fibre diets, fibre supplementation,
and/or probiotic supplementation. However, these therapies
alone or in conjuction have not yet been sufficiently evaluated
for the prevention of diverticulitis recurrence and impact on
recovery; the lack of consistency may increase patient burden,
health care costs and decrease efficacy and adherence.
Therefore, this systematic review aims to review the evidence
and develop recommendations for dietary fibre modifications,
either alone or alongside probiotics, versus any comparator
on reoccurrence, gastrointestinal symptoms and health care
use for adults following an episode of acute, uncomplicated
diverticulitis.
Methods: Intervention and observational studies in any
language were located using five electronic databases up
until March 31st, 2017, using a combination of keywords and
controlled vocabulary. GRADE was used to evaluate the overall
quality of the evidence and to develop recommendations.
Results: Three studies were included which used dietary fibre
modifications and none used probiotic supplementation. Due
to lack of consistent reporting, data could not be pooled. There
was “very low” quality of evidence for using a high dietary
fibre diet or supplements as opposed to a standard or low
dietary fibre diet following resolution of an acute episode to
improve reoccurrence and gastrointestinal symptoms. GRADE
was used to develop clinical recommendations considering
existing and generalised evidence, safety, preferences of
stakeholders, and feasibility.
Conclusions: Health care providers should recommend a
long-term high dietary fibre intake (meeting or exceeding the
nationally recommended intake for gender and age) after the
acute episode of uncomplicated diverticulitis has resolved
(strong recommendation based on very low-quality evidence).
Further well conducted randomised controlled trials are
required.
