Anisakiasis is a disease characterized by the abrupt onset of sharp epigastric pain, typically a few hours after eating raw or undercooked seafood. At present, the most common effective treatment is endoscopic removal. However, over 23 years Yamamoto has used an antiallergic drug (Stronger Neo-Minophagen C) and prednisolone to treat more than 190 patients with anisakiasis diagnosed on the basis of symptoms and without endoscopy. In this report, Kurihara reconfirms the effectiveness of this unique treatment for patients with endoscopically diagnosed anisakiasis. On the basis of these findings, we propose that the combination therapy of an antiallergic drug and a corticosteroid is a reasonable, inexpensive, and safe method for treating anisakiasis.
