Amoebic liver abscess; incodence and outcome

ABSTRACT

Amoebic liver abscess is a common infection in third world countries like ours due to poor sanitary arrangements. It presents with severe pain and high grade fever and if not diagnosed and treated promptly, may lead to complications and mortality. To estimate the incidence, need for aspiration and treatment outcome. Case series study. At respective consultations centers in Faisalabad. From 1[st], January, 2007 to 31[st] December 2008. All patients suspected of the diagnosis of liver abscess whether presenting to physicians or surgeon were referred for ultrasonography for the confirmation of the diagnosis. Basic biodata, coexisting medical or surgical diseases and relevant investigation were recorded, and patient was assessed for the need to aspirate the abscess. After initial treatment patients were reassessed for the need to aspirate the abscess on third, tenth and twentieth day both clinically and ultrasonically. We had 188 cases in the study. There were 128 [68%] males and 60 [32%] females. Majority, 156 [76.6%], of the abscesses were single, 40 [21%] had double and 4 [2%] had three abscesses. 166 [83%] were situated in the right lobe, 28[15%] in the left lobe and 4 [2%] had abscess in both lobes. 16 [9%] were aspirated at presentation due to their size or position. Only 4 [2%] were aspirated at first follow-up on third day due to non resolution of pain or fever or increase in size. All the patients who were not lost from follow up responded to standard treatment of metronidazole. Amoebic liver abscess is a common diagnosis in our setup. Patients presents with right upper quadrant pain and fever. Clinical background and ultrasonogram give a reasonable suggestion about amoebic etiology. If initial aspiration is not indicated due to size larger than 5cm. or proximity to surface or nonresolution of symptoms or lesion in left lobe, conservative treatment with oral or intravenous metronidazole is successful
