The contemporary management of parastomal varices by interventional radiology: a systematic review.
Review in CVIR endovascular, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundParastomal varices are a rare but serious complication in patients with portal hypertension, characterised by bleeding that can be life-threatening in a predominantly comorbid population. Traditional surgical approaches to managing parastomal varices are associated with high morbidity and recurrence rates, prompting increased interest in minimally invasive techniques. This systematic review aims to evaluate the efficacy and safety of interventional radiology (IR) procedures, including transjugular intrahepatic portosystemic shunt (TIPS), sclerotherapy and embolisation, in managing parastomal varices.
methodsA comprehensive literature search was conducted across multiple databases, including MEDLINE, EMBASE and Web of Science, to identify studies published up to January 2025 that reported IR interventions for parastomal varices. Data were extracted on patient demographics, procedural success, recurrence rates and complications. A pooled proportions meta-analysis was performed.
resultsFive studies, encompassing 45 patients, met the inclusion criteria. The pooled technical success rate of IR procedures was 91.3%, with a clinical success rate of 80.5% over a mean follow-up of 618.4 days. The pooled mean proportion of rebleeding, predominantly minor and non-life-threatening, was 36.4%. TIPS showed the highest efficacy, but is traditionally associated with increased procedural risks compared to other interventional radiology methods.
conclusionIR offers a highly effective and safe alternative to traditional surgical management for parastomal varices in contemporary terms. The low recurrence and complication rates highlight the potential of IR ab initio as a first-line treatment; consequently, we advocate for its use, particularly in patients unsuitable for surgery in the minimally invasive era.
