1 · What the graph read from it

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.

2 · The registry

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

Anorectal transplantation (ART) belongs to the emerging field of vascularized composite allotransplantation. Researchers have studied this procedure experimentally for over two decades as a strategy to restore anal function in patients with severe fecal incontinence and permanent colostomy. These conditions significantly impact the quality of life and pose a global public health issue. This narrative review provides a comprehensive analysis of anorectal transplantation research, covering experimental studies in animal models, and ex vivo investigations. It examines and compares different surgical techniques, considering both procedural effectiveness and functional recovery. These experiments indicate that ART can be successfully performed from a technical standpoint. Ex vivo studies demonstrate acceptable surgical times, and studies in animal models confirm graft viability and functional restoration. Future research should refine surgical techniques, investigate neural regeneration mechanisms, and develop immunosuppressive protocols to advance the field toward clinical application. ART holds the potential to completely change the treatment of severe anorectal dysfunction and permanent colostomy, offering a definitive solution to these irreversible conditions.
