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

backgroundThe Barnett continent reservoir has long been used as a surgical option for patients requiring continent ileostomies, but complications such as valve leakage, obstruction, and pouch failure often necessitate revisions. Conversion to a Kock (K) pouch offers an alternative with potentially improved outcomes. This study evaluated the safety (postoperative complications), feasibility (technical completion of conversion), and effectiveness (long-term pouch salvage) of conversion.

methodsWe conducted a retrospective cohort study of patients who underwent Barnett-to-K-pouch conversion (conversion group) or remained with a Barnett pouch (non-conversion group) between 1991 and April 2024. The conversion technique included disconnection of the afferent limb, preservation and 180° rotation of the reservoir, resection of the collar valve, creation of a stapled nipple valve, and pouch-neo-afferent limb anastomosis. Demographics, surgical history, and long-term follow-up were collected. Pouch salvage was defined as retention of a functional continent pouch; failure was defined as excision with permanent ileostomy.

resultsOut of 30 patients with Barnett pouch patients included, 16 underwent conversion and 14 did not. Median age was 51.5 versus 60.5 years, and median body mass index (BMI) was 24.7 versus 22.3 kg/m

conclusionsConversion of Barnett to K-pouch improves pouch salvage and reduces failure. While technically complex, the procedure can be safely offered to motivated patients seeking to avoid permanent ileostomy.
