Summary

This study tests whether taking spirulina tablets before and after liver surgery can protect the liver and help it recover faster. Thirty adults with bile duct cancer will take either spirulina or a placebo for three weeks before and three weeks after surgery. Researchers will measure liver function, inflammation, and side effects to see if spirulina offers any benefit.
