Acute Acalculous Cholecystitis Caused by <i>Giardia lamblia</i>

Abstract

We report a case of a 70-year-old man with acute acalculous cholecystitis caused by Giardia lamblia. Contrast-enhanced computed tomography (CT) showed distention of the gallbladder due to a pericholecystic abscess without gallstones. Magnetic resonance cholangiopancreatography and drip infusion cholecystocholangiography-CT demonstrated a stricture of the hilar bile duct and cystic duct obstruction. We conducted transpapillary bile duct brush cytology and a biopsy of the hilar bile duct stricture; numerous active trophozoites of Giardia lamblia were observed without malignant findings. We considered this bile duct lesion to be biliary giardiasis. Biliary giardiasis should be taken into consideration when diagnosing acute acalculous cholecystitis.

Abdominal Pain in the Elderly: An Unusual Case of Chronic Mesenteric Ischemia in the Emergency Department

“…He underwent a simultaneous cholecystectomy and elective revascularization of his aortic and visceral occlusive disease. Other case reports present instances of acute acalculous cholecystitis in patients with critical illness causing systemic inflammation such as a severe infection, systemic lupus erythematosus, or burns 7,8,9. Our case contrasts with the above case reports in that our patient’s abdominal pain was chronic and not present on the day of her presentation.…”

Genotypes of Giardia duodenalis in Household Dogs and Cats from Poland

“…There are two morphological stages of G. duodenalis : a trophozoite and a cyst (infective stage). The parasite can colonize the upper small intestine but it was also found in the lower small intestine, stomach, colon and biliary tract [ 3 , 7 ]. G. duodenalis transmission occurs via fecal–oral route (from contaminated water or food and directly from infected individuals) [ 5 ].…”

Closure of the Cystic Duct During Laparoscopic Cholecystectomy by the Ligasure Vessel Sealing System

“…Epidemiological studies showed gall bladder carcinoma to be the 6 th common cancer involving gastrointestinal system (Goodman and Wagman, 2010). Also, many parasites encounterred in Egypt cause acute cholecystitis, as malignant malaria (Abreu et al, 2013) ascariasis (Azhar et al, 2015), toxocariasis (Strickler et al, 2016) and giardiasis (Araki et al, 2017) as well as Staphylococcus saprophyticus, Corynebacterium urinapleomorphum, and Heliobacter pylori (Backert et al, 2018).…”
