What is the evidence for dietary modification in the management and prevention of malignant bowel obstruction? A scoping review.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeDietary modification is one tool in the multidisciplinary and multi-faceted management of malignant bowel obstruction (MBO). However, the evidence for this has not been systematically explored and no guidelines currently exist. The purpose of this review was to identify the type and breadth of published evidence available to support the use of dietary modification in MBO, and to identify key characteristics of dietary interventions and outcome measures used in evaluating these interventions.
methodsSystematic searches of three databases were conducted, last in September 2024. Title and abstract screening and full-text review were conducted before data were extracted using a data extraction tool.
resultsOnly seven records met the criteria for inclusion. Quality of interventions was low, with four abstracts, one retrospective review and two feasibility studies identified. Most interventions focused on gynaecological cancers, where MBO is most prevalent. Key characteristics of dietary modification included a low-fibre diet and modification of the texture of the diet. These approaches were often used in conjunction and in a stepwise manner (progressing from liquid to soft to low-fibre diet). All records reported benefit of dietary modification, but with limited justification. The number, type and quality of records retrieved might reflect that this is a novel area of research, with local practice and clinical experience being published as abstracts. We found no methodologically robust, large-scale interventions.
conclusionThis review demonstrates a lack of evidence to support the use of dietary modification in MBO. High-quality studies assessing the efficacy and impact of dietary modification are needed to support the advice commonly being provided in clinical settings. However, this research is ethically and logistically challenging to conduct. Nutritional management guidelines based on expert consensus might be a useful resource for clinicians managing MBO given the lack of research evidence currently available to inform practice.
