Endoscopic pedicle flap grafting in the treatment of esophageal fistulas: A case report.
Article in World journal of clinical cases, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundFistulization is a rare complication of esophageal diverticula. Patients with this condition often require surgery, which unfortunately can be invasive and traumatic. Endoscopic therapy is an alternative method for treating esophageal fistula. Hereby we introduce a new endoscopic technique that uses an esophageal pedicle flap to close esophageal fistulas. CASE SUMMARY: A 49-year-old male patient, complaining of backache and choking, was formerly diagnosed with chronic bronchopneumonia. Chest computed tomography and esophagram confirmed the presence of esophageal diverticulum and mediastinal esophageal fistula. The patient was then treated by covering the fistulas using a pedicled flap that was acquired through endoscopic submucosal dissection of a patch from the proximal esophageal mucosa. Then the pedicle flap was reversed 180° to cover the fistula. Titanium clips were used to fix the flap. The procedure ended with percutaneous endoscopic gastrostomy for enteral nutrition. The patient was followed up to evaluate the size reduction of the fistula. Cough, backache, and fever were alleviated within a week. Forty-five days after the surgery, endoscopic examination showed that the fistulas were reduced in size. The larger one reduced from 0.5 cm to 0.2 cm, while the smaller one was fully closed.
conclusionTransplantation of a pedicle flap obtained from the esophageal mucosa endoscopically is minimally invasive for the treatment of fistula.
