Multiple organ dysfunction caused by fish gallbladder poisoning: a case report and literature review.

BACKGROUND: Ingestion of raw fish gallbladder remains a rare but potentially life-threatening cause of toxin-induced multi-organ dysfunction in certain Asian regions. Case presentation: A previously healthy 57-year-old woman developed acute kidney injury and hepatic dysfunction within 24 h after ingesting a raw fish gallbladder. Rapid laboratory deterioration prompted early initiation of hemoperfusion combined with continuous veno-venous hemodiafiltration, alongside comprehensive supportive management. Organ function gradually improved, and she was discharged without permanent sequelae. Conclusions: Although the toxic effects of fish gallbladder ingestion have been described, this case highlights the importance of early recognition and structured emergency management. Prompt extracorporeal toxin removal and coordinated multi-organ support may improve outcomes in severe presentations.
