Percutaneous image-guided cryoablation of umbilical endometriosis: safety, feasibility, clinical, and imaging outcomes.
Article in European radiology, 2026. 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
objectivesTo evaluate the safety, feasibility and imaging outcomes of percutaneous image-guided cryoablation as a minimally invasive treatment for umbilical endometriosis (UE). MATERIALS AND
methodsBetween March 2017 and December 2024, 17 women (median age: 38 years; [IQR, 32-38]) underwent percutaneous cryoablation of UE at a single institution. Procedures were performed under ultrasound (US) alone or combined US/CT-scan guidance. Pain severity was assessed using the visual analog scale (VAS), imaging (US and MRI) and cosmetic outcomes were compared before and after treatment. Adverse events were reported according to the Society of Interventional Radiology classification (SIR).
resultsMedian lesion volume was 2.42 cm
conclusionPercutaneous image-guided cryoablation appears to be safe and feasible for umbilical endometriosis, offering significant pain relief, substantial nodule volume reduction and satisfactory cosmetic outcomes with predominantly minor adverse events. KEY POINTS: Question Umbilical endometriosis causes disabling pain and cosmetic concerns. Surgical excision is invasive and minimally invasive image-guided alternatives with proven efficacy and safety remain lacking. Findings Percutaneous cryoablation of umbilical endometriosis achieved durable pain relief (82%), significant nodule reduction (73%), and high cosmetic satisfaction in 82% of patients, with few adverse events, confirming its feasibility and safety. Clinical relevance Percutaneous cryoablation represents a minimally invasive, outpatient alternative to surgery for umbilical endometriosis, offering durable symptom relief and improved cosmetic outcomes, with low morbidity, potentially improving patients' quality of life and broadening therapeutic options for this rare entity.
