Worming Your Way Through the Gastrointestinal Tract: A Case of Strongyloidiasis

A 45-year-old man originally from Peru was referred for endoscopic evaluation for ongoing symptoms of generalized abdominal pain and bloating. His symptoms had been present for more than 20 years but had worsened recently. His last travel to Peru was 4 years ago. Stool examination for ova and parasite were negative. Stool cultures for Salmonella, Shigella, Campylobacter, Escherichia coli O157, and Yersinia infections also were negative. Esophagogastroduodenoscopy showed normal-appearing stomach and duodenum.
