Intestinal and biliary infection with Ascaris lumbricoides in gastrointestinal endoscopy

Abstract

A 54-year-old female patient with no relevant history underwent colonoscopy for rectal bleeding. An ascaris worm was seen at the appendiceal orifice, which was withdrawn using a polypectomy snare and sent to microbiology for diagnosis confirmation. Treatment consisted of single-dose albendazole. CASE REPORT 2A female patient was admitted because of epigastric pain radiating to the right hypochondrium, associated with nausea and vomiting, over the past 24 hours. Laboratory tests: leukocytosis 17,500/mm 3 , polymorphonuclear leukocytes 75%, amylase 1956 U/L, AST: 89 U/L, ALT 120 U/L. Abdominal ultrasounds: dilated extrahepatic bile tract with repletion defects. ERCP: dilated common bile duct with a filiform repletion defect folded onto itself, occupying the entire extrahepatic bile tract. The bile tract was cleared using a Fogarty balloon, and a cylindrical, 23-cm-long worm was withdrawn, together with biliary mud and two bile stones smaller than 10 cm in size. The bile tract was flushed with saline, and therapy with oral albendazole 400 mg for 4 days was prescribed. The patient was discharged with no symptoms on the 7 th day after admission.

“…Table 4. Selected studies reporting autochthonous and imported cases of ascariasis in the European Union (2000-2016, [26,27,28,29,30,31,32,33,34,35,36,37,57,58,82,83,84,85,86,87,88,89]). Also, we have detected more cases of parasitism in the last years in Spain than previous studies in larger countries such as the USA in the same period of time [1].…”
