The Unusual Case of Alexis St. Martin
Alexis St. Martin survived a near-fatal gunshot wound, leaving an open fistula into his stomach. Instead of sealing it, his doctor, William Beaumont, saw an opportunity for experimentation, believing he could explore the mysteries of digestion. Beaumont used this unique case to test various foods and their digestion times, which greatly advanced the understanding of the digestive process. This situation not only highlighted medical curiosity but also raised ethical questions about patient agency and the power dynamics in doctor-patient relationships.
