Endoscopic closure versus surgical revision in the management of gastrogastric fistula after Roux-en-Y gastric bypass.

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
Background: Gastrogastric fistulas (GGFs) occur in 1.3% to 6% of Roux-en-Y gastric bypass (RYGB) patients and can be associated with abdominal pain, reflux, weight regain, and onset of diabetes. Endoscopic and surgical treatments are available without prior comparisons. The aim of this study was to compare endoscopic and surgical treatment methods in RYGB patients with GGF. Methods: In a retrospective matched cohort study of RYGB patients who underwent endoscopic closure (ENDO) or surgical revision (SURG) for GGF, 1:1 matching was performed based on age, sex, body mass index, and weight regain. Patient demographics, GGF size, procedural details, symptoms, and treatment-related adverse events were collected. A comparison of symptom improvement and treatment-related adverse event rates was performed. Fisher exact test, Student Results: Ninety RYGB patients with GGF (45 ENDO, 45 matched SURG) were included. GGF symptoms included weight regain (80%), GERD (71%), and abdominal pain (67%). At 6 months, the ENDO and SURG groups experienced 0.59% and 5.5% total weight loss (TWL) ( Conclusion: Endoscopic GGF treatment produces greater improvement in abdominal pain and fewer overall and serious treatment-related adverse events. However, surgical revision appears to yield greater weight loss.
