TWO CASES OF NECATOR AMERICANUS DIAGNOSED AND CAPTURED BY DUODENOFIBERSCOPY

Abstract

The prevalence of parasites has decreased remarkably due to an improvement of public health, but in some cases parasite infection causes abdominal symptoms. So it is necessary to recall parasitic infection when diagnostic screening of abdominal symptoms is made. Some cases that ascaris lumbilicoides or anisakis parasited in the digestive tract were captured by the f iberscope are reported but Necator americanus is too small to be found by X-ray series and is easily overlooked during endoscopic examination. Here two such cases of Necator americanus infection were reported. The patients came to the hospial with chief complaint of epigastric pain. ERCP was intended to be performed in order to diagnose pancreatitis or not. On that occasion Necator americanus (red in color) were found moving near the duodenal papilla and they were captured using biopsy forceps. One patient was found to have chronic pancreatitis but the other had no leision and the both have enjoyed their life since the insecticide was prescribed.
