Insufflation esophagoscopy.

A new electroscope has been designed from the conventional Haslinger tubes. The new rigid scope combines the advantage of air insufflation in the flexible system with the therapeutic possibilities of the rigid tubes and is trustworthy in the following esophageal procedures; a) finding entrance of severe strictures; b) introducing nasogastric feeding tubes; c) extraction of foreign bodies; d) tumor coagulation/spur in hypopharyngeal diverticuli; e) washing and suction in cases with severe food retention; f)making tumor smears in patients with clotting disorders; g) taking substantial biopsies with an optical forceps, and h) objective photodocumentation of esophageal pathology.
