Background: Erythropoietic protoporphyria is a rare disease of heme biosynthesis resulting in excessive accumulation of protoporphyrin in various organs. The most typical symptom is photosensitivity caused by activated protoporphyrins (wavelength ~400 nm). Accumulated protoporphyrin in the liver also causes liver failure, and liver transplantation is the only life-saving treatment. Phototoxic injury to abdominal organs has been reported during liver transplantation. Thus, to avoid phototoxic injury during liver transplantation, it has previously been conducted with only shadowless lights and ceiling lights off in the operating theater. Here, we report a case of a safe and successful liver transplantation in a patient with erythropoietic protoporphyria where the operating theater lights were covered with polyimide film. Case presentation: A 50-year-old man presented with hepatic failure owing to erythropoietic protoporphyria. Before liver transplantation, the shadowless lights and ceiling lights in the operating theater were covered entirely with polyimide film. This filter completely blocked the harmful wavelength of light (400-470 nm). Orthotopic liver transplantation was safely and successfully performed with adequate illumination and patient monitoring. The patient followed a normal postoperative course without phototoxic injuries or protoporphyrin re-accumulation. Conclusion: Covering not only shadowless lights but also all ceiling lights in the operating theater with the polyimide film allowed safe surgery, safe anesthesia, and safe monitoring of the patient who underwent liver transplantation for severe liver failure owing to erythropoietic protoporphyria.
