All of the following are TRUE about amoebic liver abscess, EXCEPT:
Correct Answer: Shows male preponderance of 4:1
Description: "Male preponderance of greater than 10:1 has been repoed in all studies" "A recent retrospective study comparing surgical with percutaneous drainage for large (>5 cm) abscess showed a better success rate with surgical drainage" "Percutaneous drainage of multiple abscess is usually met with a higher failure rate" "Like pyogenic liver abscess, amoebic liver abscess also tend to occur mainly in right liver" The mainstay of treatment of amoebic liver abscess is metronidazole (750 mg orally three times per day for 10 days), which is curative in more than 90% of patients. In general, aspiration is recommended for diagnostic unceainty, failure to respond to metronidazole therapy in 3-5 days, or in abscess felt to be at high risk for rupture. Abscess larger than 5cm in diameter and in the left liver are thought to be a risk for rupture, and aspiration need to be considered.
