Postendoscopic Mucosal Injury Syndrome Mimicking Postpolypectomy Electrocoagulation Syndrome After Colonoscopic Biopsy.

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 case report describes a rare, severe presentation of postendoscopic mucosal injury syndrome mimicking postpolypectomy electrocoagulation syndrome (PPECS) in a 40-year-old woman. After an uncomplicated colonoscopy with mucosal biopsies, the patient developed septic shock with hemodynamic instability, requiring intensive care. Computed tomography findings raised suspicion for colonic perforation, prompting an exploratory laparotomy. Surgical exploration, however, revealed no perforation but significant serosal inflammation and reactive lymphadenopathy consistent with a PPECS-like inflammatory process. This case highlights the diagnostic challenge of distinguishing severe PPECS-like presentations from true perforation and underscores the potential for life-threatening complications even in the absence of documented electrocautery or polypectomy.
