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

purposeLaparoscopic sleeve gastrectomy (LSG) is the most frequently performed procedure; however, the treatment of staple line leakage is very complicated. Therefore, this study assessed the incidence and treatment outcomes of staple line leakage in Japan.

methodsThe first survey of patients with leakage after LSG until September 30, 2022, was sent to 83 Japanese institutions. The second survey was sent to institutions that reported patients with leakage after LSG. The timing of conversion to curative surgery was statistically analyzed.

resultsThirteen institutions (15.7%) reported staple line leakage in 21 patients after LSG. The incidence was 0.41%, and the leakage sites were close to the angle of His in > 90% of the patients. Initial management was successful in 30.0% of patients, while the remaining patients required additional management. After intervention, 25.0% of patients underwent conversion surgery as curative management, and the optimal timing was 83.5 days after leakage detection.

conclusionsThe rate of staple line leakage after LSG was low, but difficult to treat. Conversion to curative surgery may be determined after approximately 12 weeks.
