Intraperitoneal rupture of amoebic liver abscess.

A retrospective analysis of 23 cases of amoebic liver abscess with intraperitoneal rupture is presented. Group I consisted of 16 patients with clinical features of generalized peritonitis. Eight of these patients were treated surgically, and four died. Group II consisted of seven patients with features of localized peritonitis and all were treated conservatively. In all cases the diagnosis of liver abscess was established by liver scan or ultrasound examination; peritonitis was established either at operation or, in the conservatively managed group, by aspiration of pus from the peritoneal cavity. Amoebiasis was diagnosed by serology. Eight group I and all group II patients were managed conservatively by aspiration of the liver abscess, antibiotics and amoebicides. There were no deaths in this group. It is suggested that, if the diagnosis can be made early, conservative treatment offers the best chance of cure for patients of amoebic liver abscess with intraperitoneal rupture.
