Proximal sigmoid fecaloma after stapled hemorrhoidopexy: a diagnostic pitfall and stepwise nonoperative management.
Article in Journal of surgical 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
Stapled hemorrhoidopexy (SH) is used for prolapsing hemorrhoids and is associated with less short-term postoperative pain. While constipation is common after SH, proximal sigmoid fecaloma is rarely reported. We report a 49-year-old woman who presented with severe abdominal pain and obstipation 14 days after SH. Although digital rectal examination revealed an empty rectum, computed tomography (CT) demonstrated a large fecaloma in the proximal sigmoid colon, 15 cm proximal to the intact staple line. A rectal tube enema failed, but a targeted high enema via flexible sigmoidoscopy achieved partial softening, followed by successful evacuation with nasogastric polyethylene glycol irrigation. This case highlights that an empty rectum on digital examination does not exclude proximal fecal impaction after SH. Early CT may help differentiate proximal fecaloma from staple-line complications and support stepwise nonoperative management in selected stable patients.
