Case Report: Endoscopic full-thickness resection using dual and IT knives for a false gastric diverticulum and systematic review.

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
Gastric diverticula are the rarest gastrointestinal diverticula, traditionally managed medically or surgically. We report a case of a long-standing gastric diverticulum with postprandial abdominal pain refractory to acid suppressive therapy for the past year, successfully treated by endoscopic full-thickness resection (EFTR). A 56-year-old woman presented with a 20-year history of postprandial left upper quadrant pain that had initially responded to proton pump inhibitors (PPIs) but became refractory over the past year. Repeated endoscopies revealed a gastric diverticulum with food impaction. She underwent EFTR for resection of the lesion. The postoperative course was uneventful, with no complications, and she recovered well. Postoperative histopathology confirmed a false gastric diverticulum lacking the muscular layer, with no evidence of neoplasia. At one month follow up, her abdominal pain had resolved, and endoscopy showed good healing of the resection site. This case suggests that EFTR is an effective treatment option for small, medication-refractory gastric diverticula. However, further studies are needed to define its optimal indications. Given the potential risk of coexisting neoplasia in false diverticula, more aggressive management and careful histopathological examination may be warranted.
