Comparison of CT-guided intracystic lidocaine pre-injection versus conventional US-guided single-session ethanol sclerotherapy for simple hepatic cysts.

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
This study aimed to compare a modified CT-guided technique incorporating intracystic lidocaine for pain control versus a conventional ultrasound-guided method for single-session ethanol sclerotherapy of simple hepatic cysts (SHCs), to seek refinements in technical strategies. 113 patients with SHCs underwent ethanol sclerotherapy between January 2019 and June 2023 at two centers. Center A utilized a modified CT-guided technique with intracystic lidocaine pre-injection into the cyst. Center B employed a conventional ultrasound-guided method with pigtail catheter drainage. Primary endpoints included pain during ethanol injection, procedural duration, and safety, while secondary endpoints assessed cyst volume reduction and symptom relief. 99 eligible patients (Center A/B, n = 43/56) were included in the analysis. The modified technique at Center A resulted in significantly lower median VAS scores (1.2 ± 1.2) compared to Center B (5.1 ± 1.1; p < 0.01) during ethanol injection. Ethanol exposure and procedural durations were also shorter at Center A (11.2 ± 1.6 min and 29.9 ± 4.3 min) than at Center B (20.5 ± 3.4 min and 40.6 ± 4.2 min; p < 0.01). No complications were observed at Center A. Both centers achieved similar success rates in reducing cyst size and relieving symptoms at the 6-month follow-up. The modified CT-guided percutaneous single-session ethanol sclerotherapy technique for SHCs significantly reduces pain and procedural duration compared to the conventional method, with similar efficacy and safety profiles.
