A Case of Partial Intestinal Obstruction due to Ascaris lumbricoides / 대한소화기내시경학회지

ABSTRACT

Ascaris lumbricoides (A. lumbricoides) is the largest and most common human intestinal helminth in the world. However, the prevalence of ascariasis has, in recent years, been very low in Korea. The majority of patients infected with A. lumbricoides are asymptomatic. However, sometimes these infections may give rise to intestinal obstructions or pancreatobiliary disease, via retrograde migration through the ampulla of Vater. Intestinal obstruction associated with A. lumbricoides is a complication that is frequently observed in children living in endemic areas. However, no cases of A. lumbricoides-associated intestinal obstruction have been reported in Korea since 1967. In this report, we describe the case of a 78-year-old man, who presented with sustained nausea and postprandial vomiting, and was diagnosed with a partial intestinal obstruction due to A. lumbricoides after undergoing an esophagogastroduodenoscopy.
