For 10 years, 26 patients underwent treatment for complications caused by presence in the stomach and intestine of the foreign bodies with low radio-opacity and echogenicity. All the patients were operated on. At operation, a cause of the disease was established: in 17 cases--a fish bone, in 5--a small chicken bone, in 1--a conifer needle, in 2--a wooden chip, in 1--a home-made toothpick.
