UNLABELLED: In the school year 2002/2003 there were examined in Poland some of the population of 7-year-old children for the presence of intestinal parasites, continuing countrywide operation launched in 1988. METHODS: The studies were based on the examination of a single faecal specimen and a cellophane swab using the following methods: wet mount preparations in 0.9% NaCl and diluted Lugol's ioine, zinc sulphate centrifugal flotation and decantation. RESULTS AND CONCLUSIONS: The studies included 31 504 children from 15 provinces of Poland. The parasites most frequently encountered in the examinations included: Enterobius vermicularis (in 3 827 of the examined, i. e. 12, 15%), Ascaris lumbricoides (in 263; 0.83%), Giardia intestinalis (in 217: 0.69%), Entamoeba coli (n 189; 0.60%) and Trichuris trichiura (in 39; 0.12%) The overall percentage of the infected children was 15.4%. The highest number of infected children was found in the province warmińsko-mazurskie (29.6%0), the smallest in slaskie (8.8%). The number of infected among children inhabiting country (19%) was significantly higher than among those from the towns (10.4%). The obtained results confirmed hitherto existing views that in Poland the epidemiological situation of infections with intestinal parasites is steadily improving.
In a 60-year-old woman who underwent cholecystectomy and T-tube drainage for biliary ascariasis, postoperative bilirubin levels continued to increase. T-tube cholangiography revealed multiple filling defects in the bile ducts, which suggested roundworm reinfestation. Because the patient could not tolerate endoscopy, a percutaneous transhepatic approach with balloon dilatation of the ampulla of Vater and subsequent advancement of roundworms into the duodenum with an embolectomy balloon was used. The procedure was successful, with no major complications. The use of a percutaneous transhepatic treatment to advancement of roundworms into the duodenum is a feasible alternative to surgery when endoscopic extraction fails.
