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

backgroundPostoperative anastomotic leakage is a severe complication after gastric tube reconstruction during esophagectomy. The aim of this study was to evaluate the usefulness of postoperative endoscopic assessment of anastomosis and its correlation with intraoperative indocyanine green (ICG) fluorescence assessment of the gastric tube.

methodsWe retrospectively reviewed 72 consecutive patients who underwent gastric tube reconstruction using the ICG fluorescence method during esophagectomy. Forty-six patients underwent the ICG line-marking method (LMM group; ICG before gastric tube creation). The other 26 underwent the conventional procedure and comprised the control group (ICG after gastric tube creation). Postoperative endoscopic assessment (PEA) of anastomosis was performed 7 days after surgery and results were classified as follows: grade 1 (normal or partial white coat), grade 2 (ulcer comprising less than half the circumference), and grade 3 (ulcer comprising more than half the circumference).

resultsAnastomotic leakage occurred in 7 of 72 patients (9.7%). The incidence of anastomotic leakage in the LMM group was tended to be lower than those in the control group (6.5% vs. 15.4%; P = 0.244). Of the 40 patients who underwent PEA, 3 (7.5%) had leakage. PEA grading was significantly associated with anastomotic leakage (P < 0.001). Better intraoperative ICG assessment was significantly associated with better endoscopic assessment grade (P = 0.041).

conclusionIntraoperative ICG assessment of the gastric tube was associated with PEA grading on anastomosis during esophagectomy.
