Amebic peritonitis
Abstract:
A total of 18 patients with amebic peritonitis were studied. Fourteen of these cases were due to rupture of amebic liver abscess into the peritoneum and the remaining cases were due to perforation of amebic colitis. No initial suspicion of amebic etiology was made in more than half of the cases. In the group of ruptured liver abscesses, nearly half of the patients showed right lower lung syndrome. The diagnosis in 13 of 14 cases of rupture of liver abscess was confirmed on aspiration. Patients with ruptured amebic liver abcess were of two types: 1. Diffuse type with diffuse signs, shorter duration of illness and poor prognosis. 2. Localized type with longer duration of illness, marked signs of peritonitis and better prognosis. Once the diagnosis of peritonitis was made, the management was surgical. Conservative treatment was tried only in cases with signs of localization. The mortality rate had been 33% in amebic liver abscess rupturing into the peritoneum and 75% in perforation of the intestine. A high index of suspicion of amebiasis in patients with an acute abdomen and institution of early treatment are recommended to help in reducing this mortality. Amebic liver abscess and amebic dysentery should be treated energetically to avoid this fatal complication and surgical intervention whenever indicated should not be delayed.
Insights
Amebic peritonitis, often from liver abscess rupture, requires high suspicion for early diagnosis and treatment. Prompt surgical intervention improves outcomes, reducing high mortality rates associated with this condition.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Surgical Pathology
Background:
- Amebic peritonitis is a severe complication of amebiasis.
- Etiologies include rupture of amebic liver abscess and perforation of amebic colitis.
- Amebic etiology is often not suspected initially.
Purpose of the Study:
- To analyze the clinical presentation, diagnosis, management, and outcomes of amebic peritonitis.
- To identify factors influencing prognosis in patients with amebic peritonitis.
Main Methods:
- Retrospective study of 18 patients with amebic peritonitis.
- Review of clinical data, diagnostic methods (including aspiration), and treatment approaches.
- Classification of ruptured amebic liver abscess cases into diffuse and localized types.
Main Results:
- Rupture of amebic liver abscess accounted for 14 cases; 4 cases were due to amebic colitis perforation.
- Right lower lung syndrome was observed in nearly half of ruptured liver abscess cases.
- Mortality rates were 33% for ruptured liver abscess and 75% for intestinal perforation.
- Localized type of ruptured liver abscess had a better prognosis than the diffuse type.
Conclusions:
- A high index of suspicion for amebiasis is crucial in patients presenting with an acute abdomen.
- Early diagnosis and energetic treatment of amebic liver abscess and dysentery are vital.
- Timely surgical intervention is recommended to reduce mortality in amebic peritonitis.
