[Early management of foreign bodies in the upper digestive tract with flexible fiberendoscopy]. / Manejo precoz de los cuerpos extraños en el tracto digestivo superior con fibroendoscopia flexible.

We present our five year experience (1983-1988) in 74 patients who intentionally or accidentally ingested foreign bodies, and their management with flexible fibroendoscopy. A higher incidence was observed in children under 6 years of age, and adults between 30 and 50 years of age. The major presenting symptom was the "sentation of foreign body", and 24% of patients presented no symptomatology. The most commonly encountered foreign bodies were: fishbone, coins, chicken bones, and meat fragments. An esophageal location was the most commonly found, predominantly in the proximal third. Flexible endoscopy performed in 59 patients (80%), successfully removing the foreign body in 93.2%. In the remaining cases it was demonstrated previously that the foreign body could not be reached by the endoscope.

[Strongyloidiasic hyperinfestation]. / Hiperinfestación strongyloidiásica.

A study was made of twelve cases of fatal Strongylodiasis with Hyperinfestation which presented a severe picture of the small intestine and colon, some with localization in the lungs, bronchus, and other organs. Preliminary results are given of a prospective study related to the bacterial flora and its role in the pictures of larvarial aggression, which could lead to greater knowledge about the biology of the parasite, and therefore to interesting findings of a therapeutic nature.
