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

introductionEsophageal atresia (EA) Gross type A is a congenital malformation in which both the upper and lower esophagus have blind ends without a tracheoesophageal fistula. The gap between the segments is often long (long-gap EA), making intraoperative localization challenging. We report a case in which the lower esophageal blind end was readily localized using Tumguide (Otsuka Pharmaceutical Factory, Tokushima, Japan), a device that transmits biologically transparent red light from a light-emitting diode (LED) through an optical fiber. CASE PRESENTATION: The patient was a 2-month-old girl diagnosed at birth with EA Gross type A. A gastrostomy was performed shortly after birth, and esophageal lengthening with the Howard procedure was carried out over the following month. At 2 months of age, she underwent delayed primary esophageal anastomosis. At the start of surgery, the Tumguide was inserted through the gastrostomy site into a Salem Sump gastric drainage tube. The device provided clear localization of the lower esophageal blind end, minimizing the need for dissection of surrounding tissues.

conclusionsFiber-guided red LED illumination, using Tumguide, enabled safe and straightforward intraoperative localization of the esophageal blind end in long-gap EA Gross type A. This approach minimized the need for dissection, thereby reducing the risks of injury to surrounding tissues and postoperative complications such as anastomotic stricture and leakage.
