Feasibility of a new bariatric fully endoscopic duodenal-jejunal bypass: a pilot study in adult obese pigs.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
This study assessed a new natural orifice transluminal endoscopic surgery (NOTES) bariatric endoscopic procedure in obese adult pigs. This 14-week prospective study compared 6 adult male Yucatan test pigs with baseline mean age 1.5 years to 2 control pigs. The test pigs received a fully endoscopic NOTES-based duodenal-jejunal bypass including measurement of the bypassed limb and creation of a gastrojejunal anastomosis (GJA) using a gastrojejunal lumen-apposing metal stent (GJ-LAMS) at Week 0, placement of a duodenal exclusion device (DED) at Week 2, and endoscopic examinations at Weeks 6 and 10. At Week 14, the pigs were sacrificed for necropsy. All endoscopic procedures were technically successful. By Week 14, the controls had gained a mean 1.1 ± 2.1 kg (+ 1.6%) while the intervention animals lost a mean 6.8 ± 3.9 kg (- 10.5%) since baseline. GJ-LAMS migrations occurred in 3 pigs, two of which also had DED migration and/or partial dislocation. Two other pigs died, one with aberrant splenic vein positioning near the GJA and the other from an unknown cause. An endoscopic bariatric bypass procedure with controlled bypass length was technically successful in all the cases and led to weight loss in test animals. Safety concerns must be further addressed.
