Wriggling Worms in the Gut During Endoscopy

1. Image 1 A 71-year-old man presented to the outpatient clinic with a 10hour history of severe cramping epigastric pain. He reported that he ate sea eel sashimi a day ago. On physical examination, tenderness of the epigastrium was noted and the initial laboratory test results were unremarkable. Esophagogastroduodenoscopy showed a light-gray colored, 2.5 cm-length linear worm wriggling on the posterior wall of the lower body of the stomach. One side of the worm penetrated into the gastric wall, with the mucosa showing localized erythema, swelling, and exudate. The worm and surrounding gastric mucosa were grasped with forceps and removed slowly and gently (Figure 1).
