Amebic peritonitis secondary to amebic liver abscess

Area of Science:

• Gastroenterology
• Hepatology
• Infectious Diseases

Background:

• Amebic liver abscess (ALA) is a common parasitic infection, but its rupture leading to amebic peritonitis is a rare and serious complication.
• This study focuses on the clinical presentation, management, and outcomes of patients with amebic peritonitis secondary to a ruptured ALA.

Purpose of the Study:

• To present a series of patients with amebic peritonitis secondary to ruptured amebic liver abscess.
• To analyze the clinical characteristics, surgical management, and mortality factors associated with this condition.

Main Methods:

• Retrospective review of 19 patients treated for amebic peritonitis secondary to ruptured ALA over an 18.5-year period.
• Surgical management included removal of necrotic material, wide drainage, and in select cases, intestinal bypass.

Main Results:

• Amebic peritonitis represented 2.4% of ALA cases. The majority of patients were male, with ages ranging from 6 to 70 years.
• Common symptoms included abdominal pain and fever; physical findings included abdominal tenderness, liver enlargement, distention, and jaundice.
• The overall mortality rate was 42%, significantly higher in patients over 50 years and those with incorrect preoperative diagnosis.

Conclusions:

• Rupture of an amebic liver abscess leading to peritonitis is associated with high morbidity and mortality.
• Early and accurate diagnosis, followed by prompt surgical intervention, is critical for improving patient outcomes.
• Advanced age and delayed diagnosis are significant risk factors for increased mortality in amebic peritonitis.
