Anatomical distribution of hemorrhoidal piles in advanced disease: clinical insights and correlations.
Article in Techniques in coloproctology, 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
backgroundA precise evaluation of the positional distribution of hemorrhoidal piles has not been distinctly conducted. We hypothesized that the distribution of hemorrhoidal piles follows a predictable anatomical pattern influenced by disease duration and recurrence.
methodsOur retrospective study analyzed the demographic data, surgical records, operative photographs, previous treatments, and associated colorectal symptoms of patients who underwent invasive procedures for advanced hemorrhoidal disease (2020-2024).
resultsOf the 171 patients (123 male; 71.9%; median age 41 ± 12.04 years, range 18-88), 35 had prior interventions (recurrent cases). The largest pile was most commonly in the left lateral quadrant (40.14%), followed by right posterior (31.97%), right anterior (23.47%), and atypical locations (4.42%). Left lateral predominance was significantly higher in primary cases than in recurrent cases (p = 0.031). Most patients had more than one pile (87.7%). Symptom duration positively correlated with pile number (Spearman's rho = 0.229, p = 0.013), but not with hemoroid grade (p = 0.977). No significant differences in pile distribution were observed in patients with defecation disorders, labor history, or concomitant anal fissure (p > 0.05). Of the 48 patients with anal fissure had significantly shorter symptom duration compared to those without fissure (p = 0.011).
conclusionThe classical three-quadrant distribution is confirmed, with the left lateral pile being predominant in primary cases. The association between prolonged symptom duration and increased pile number offers novel insights, highlighting left lateral predominance in primary cases and its reduction in recurrence, enhancing clinical understanding and management.
