Successful treatment of Diphyllobothrium latum and Taenia saginata infection by intraduodenal 'Gastrografin' injection.

Tapeworm infections are very difficult to cure completely. Thirteen patients with tapeworm infection, seven with Diphyllobothrium latum and six with Taenia saginata, were treated by the introduction of a radio-opaque contrast medium, 'Gastrografin', into the duodenum through a duodenal tube. The whole tapeworm with the scolex was expelled unfragmented within 1 h in eleven cases. One patient expelled a tapeworm 3 days after treatment; the peristalsis of his intestine had been severely disturbed after an attack of cerebral apoplexy. The tapeworm could not be expelled by the remaining patient, probably because she had severe intestinal adhesion. The injection of gastrografin allowed clear visualisation of the tapeworm, the diagnosis of the infection could be confirmed, and the descent of the tapeworm could be observed serially. This treatment had no serious adverse effects in any of out patients.
