Benign lesions prolapsing through the anus: a differential diagnostic algorithm and evidence-based surgical management-a narrative review.
Review in Frontiers in surgery, 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
Masses prolapsing through the anus represent a frequent diagnostic challenge in coloproctological practice. Misidentification may delay the management of malignant disease or surgical emergencies. This narrative review integrates current evidence on seven benign entities that may prolapse through the anus-complete rectal prolapse, mucosal rectal prolapse, internal hemorrhoids, thrombosed hemorrhoids, anal condylomas, hypertrophied anal papilla, and anal canal polyps-and proposes a clinical decision algorithm based on findings from physical examination. Particular emphasis is placed on the identification of red flags that require exclusion of malignancy or surgical emergency. The evidence supporting the different therapeutic options is critically analyzed. The proposed algorithm prioritizes objective clinical characteristics-fold pattern, texture, mobility, and anatomical location-to guide differential diagnosis and the sequence of complementary studies, optimizing surgical decision-making.
