Gallbladder decompression and hydrodissection as adjuncts for ablation of pericholecystic hepatocellular carcinomas.
Article in Radiology case reports, 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
Microwave ablation is an effective treatment for hepatocellular carcinoma, but tumors adjacent to extrahepatic organs carry a higher risk for thermal injury. Thermoprotective techniques such as hydrodissection and gallbladder decompression can reduce this risk and expand the range of lesions amenable to percutaneous treatment. We present a case of a 68-year-old woman with hepatocellular carcinoma in hepatic segment V, with partial treatment response from prior transarterial chemoembolization. Due to the lesion's proximity to the gallbladder and transverse colon, microwave ablation was performed with concurrent ultrasound- and CT-guided gallbladder decompression and hydrodissection. The ablation was technically successful without post-procedural complications. At 12-month follow-up, MRI demonstrated no residual tumor. This case highlights the feasibility of microwave ablation in anatomically challenging locations using thermoprotective strategies, overcoming technical challenges that may otherwise preclude minimally invasive treatment.
