Jejunojejunostomy intussusception following conversion from gastric sleeve to gastric bypass: a case report.
Article in Journal of surgical case reports, 2026. 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
A 46-year-old woman presented 15 months after laparoscopic conversion of sleeve gastrectomy to Roux-en-Y gastric bypass with acute abdominal pain and lactic acidosis. Computed tomography demonstrated free intraperitoneal air and mesenteric swirl sign concerning for jejunojejunal intussusception. Emergent laparoscopy revealed retrograde intussusception at the jejunojejunostomy with three bowel perforations and feculent peritoneal contamination. After reduction, intraoperative assessment confirmed bowel viability with successful reperfusion, allowing primary two-layer repair of enterotomies rather than segmental resection. A Brolin stitch was placed to prevent recurrence, and the incidentally discovered Petersen space defect was closed with permanent suture. Despite developing postoperative septic shock requiring vasopressor support and intensive care, the patient recovered completely with preserved bowel length and normal function at follow-up. This case highlights the importance of prompt surgical intervention for post-bariatric intussusception and demonstrates that primary repair may be feasible when careful intraoperative assessment confirms bowel viability.
