Preoperative splenic artery embolization in moderate splenomegaly undergoing elective laparoscopic splenectomy: a randomized controlled trial.
Trial report in Surgical endoscopy, 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
backgroundLaparoscopic splenectomy (LS) for moderate splenomegaly remains technically demanding due to limited working space and increased vascularity. Pre-operative splenic artery embolization (SAE) has shown benefits in massive splenomegaly, but its role in moderate cases is unclear.
methodsThis open-label randomized controlled trial was conducted at a tertiary care center. Patients aged 15 years and above with moderate splenomegaly undergoing elective LS were randomized into two groups: Group A (pre-operative SAE + LS) and Group B (LS alone). Primary outcomes included intra-operative blood loss, conversion to open surgery, mean operative time, and post-operative length of stay. Secondary outcomes included short-term post-operative complications and post-splenectomy hematological changes.
resultsA total of 40 patients were randomized (20 per group). The intraoperative blood loss was comparable between Group A [100(50-550)] ml and Group B [100(50-2000)] ml, p < 0.228). The conversion rates were similar across both groups (5% in Group A vs. 10% in group B). Operative time was slightly longer in Group B (79.9 ± 19.2 min) compared to Group A (90.5 ± 32.0 min; p = 0.210), but not statistically significant. Mean post-operative hospital stay was similar (4.35 ± 0.8 days in Group A vs. 4.75 ± 1.4 days in Group B) Post-operative complications, including pancreatic leak and atelectasis, were similar across both the groups.
conclusionThe results of preoperative SAE with LS are equivocal to LS alone in patients undergoing elective LS for moderate splenomegaly. While SAE resulted in reduced intraoperative blood loss, the results were not statistically significant. Randomized trials with larger sample sizes and multicentric studies are required to achieve a consensus.
