The patient was given conservative treatment in the form of bowel rest,intravenous fluids and painkillers. After 24 hours of admission, pain subsided. Upper GI endoscopy showed worm movement in duodenam (Figure 2B and 2B) and subsequently with the help of endoscopic snare a worm was taken out (Figure 3).The patient responded to conservative management and on the second day of admission he passed stool. Stool examination revealed presence of fertilized and unfertilized eggs of ascariasis (Figure 4A and 4B). Antihelminthic was administered in the form of albendazole and discharged.

Ascaris lumbricoides is one of the commonest helminthic infections worldwide. Adult worms may be present in gastrointestinal system, hepatobiliary system or peritoneal cavity causing a wide range of clinical manifestations [1]. Straight X ray abdomen can reveal moderately distended small bowel loops,sometimes multiple air-fluid levels. Sonography of abdomen confirms the diagnosis of ascariasis by the presence of the typical signs of “bull’seyes” in transverse section and “railway track” appearance in longitudinal sections [2]. The finding of fertile or infertile eggs or an adult worm in the feces may sometimes serve as only an indicator of ascariasis lumbricoides infestation [3].
