Acute massive gastric dilatation with necrosis and portal vein gas accumulation-a case report.
Article in Frontiers in medicine, 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
Acute gastric distension (AGD) is a rare but life-threatening acute abdominal condition. Despite the rich blood supply to the stomach, extreme distension can lead to ischemic necrosis, perforation, and gas accumulation in the portal vein, with a mortality rate as high as 80-100%. We report the case of a 15-year-old male patient who presented with severe abdominal pain, bloating, and vomiting following a binge-eating episode. Physical examination revealed signs of diffuse peritonitis and shock (heart rate 154 beats per minute). Laboratory results showed severe metabolic acidosis (pH 7.265) and hyperlactatemia (11.3 mmol/L). An abdominal CT scan confirmed massive gastric distension and gas accumulation in the portal vein, biliary tract, and esophageal wall. The patient underwent emergency laparotomy within 2 hours of admission. Intraoperatively, the stomach was found to be distended into the pelvic cavity, with two areas of hemorrhagic necrosis: one on the lesser curvature (4 cm × 5 cm) and another on the posterior wall of the greater curvature (3 cm × 4 cm). Gastric decompression, debridement of the necrotic areas, and creation of a gastrostomy were performed. After 5 days of intensive care unit (ICU) monitoring (for treatment of septic shock), the patient recovered well and was discharged on the 14th postoperative day; follow-up revealed no recurrence. This case demonstrates that even healthy individuals without eating disorders may develop AGD due to acute binge eating. Portal air is a critical warning sign of mucosal necrosis. Early diagnosis via CT and prompt surgical decompression are key to saving the lives of patients with ischemia and shock.
