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.

We report on a 30-year old patient suffering from acute abdomen. X-ray examinations (abdomen photograph, passage of contrast medium) showed an obstructive ileus of the small bowel. Exploratory laparatomy revealed an obstruction of the small bowel by means of masses of lymphatic nodes as part of a mesenteric lymphadenopathy. M. tuberculosis was identified as growing in cultures of peritoneal smears and material of lymphatic nodes. The retrospective examination of the pre-operative x-ray photographs of the chest showed an old primary complex of the lung. A combination of four antituberculotic drugs: Rifampicin, ethambutol, isoniazid and pyrazinamid was administered following the concept of a 6-month regimen. This treatment was successful: CT-scans of the abdomen showed a reduction of the mesenterial lymphadenopathy and the disappearance of the duodenal impression in the follow-up after 4 weeks of therapy. The abdominal TBC represents a severe disease requiring a differential diagnostic distinction from other abdominal diseases such as ileitis terminalis, Crohn's disease, neoplass as especially gastrointestinal lymphomas, giardiasis, amoebiasis and yersinia enterocolitis. The disease has a special importance among immigrant populations.

Amoebic liver abscess is the commonest extra intestinal manifestation of amoebiasis. Intraperitoneal rupture of liver abscess and fulminant necrotizing amoebic colitis are rare occurrences which complicate a severe form of invasive disease caused by Entamoeba histolytica. These complications are associated with a high morbidity and mortality. Synchronous pathological lesions in colon and liver are rare. Still rare is the occurrence of complicated colonic and hepatic invasive amoebiasis presenting as an acute abdomen. One such presentation of ruptured liver abscess and necrotizing amoebic colitis in a 70 year old male which was successfully managed is being reported.

Amoebiasis, a disease of worldwide distribution, is endemic in tropical countries with suboptimal sanitation facilities. Isolated amoebic appendicitis (IAA) is regarded as a rare manifestation of the disease globally. Because there are no defined clinical features that distinguish IAA from bacterial appendicitis, diagnosis is usually dependent on histopathological examination. A 9-year retrospective study was undertaken to investigate the clinicopathological aspects of IAA. The main complaints were fever and abdominal pain. None of the patients had dysentery. The pre-operative clinical diagnosis was acute appendicitis and acute abdomen in 13 and 8 patients, respectively. In all cases the intra-operative diagnosis was acute appendicitis. Gross pathological appraisal revealed peritonitis and perforation in 19 and 17 cases, respectively. Histopathological examination of these appendices demonstrated appendiceal ulceration, transmural mixed inflammation, haematophagous amoebic trophozoites and necrosis in all cases. Vascular pathology comprised venous and capillary luminal plugging (11 cases), necrotising small vessel vasculitis (11 cases), thrombophlebitis of medium sized veins (9 cases) and arteritis with associated thrombosis (1 case). Organising fibrinopurulent peritonitis was present in 19 cases. Two appendices that appeared normal macroscopically demonstrated ulceration and inflammation that were confined to the mucosa and submucosa. All of 18 patients who were treated with metronidazole survived without further surgery, while three patients who were untreated succumbed to the disease. Appendicectomy, accurate histopathological appraisal thereof and optimal, timely management of IAA were critical to the favourable outcome in the present study.

Strongyloides stercoralis (SS) is an intestinal nematode that is mainly endemic in tropical and subtropical regions and sporadic in temperate zones. SS infection frequently occurs in people who have hematologic malignancies, HIV infection and in individuals undergoing immunosuppressive therapy. In this study, we report a 12- year-old immunocompetent boy who was admitted to our hospital with acute abdomen. Laboratory evaluation showed strongyloidiasis, amebiasis and giardiasis. Clinical and laboratory findings immediately improved with albendazole therapy. Therefore, when diarrhea with signs of acute abdomen is observed, stool examinations should be done for enteroparasitosis. This approach will prevent misdiagnosis as acute abdomen. Complete clinical improvement is possible by medical therapy without surgical intervention.

Acute Fulminant Necrotizing Amoebic Colitis is a rare complication of amoebiasis that is associated with high mortality. Only one to four such cases are seen per year in large hospitals of India, and only few such cases have been reported in the literature. The condition requires early diagnosis and surgical intervention. We recently cared for a patient who presented with acute abdomen with history of intermittent abdominal pain and diarrhea. Before presenting to our institution he was misdiagnosed as a case of inflammatory bowel disease and had been treated with steroids. On emergency exploration, extensive necrosis and multiple perforations in retroperitoneum involving entire colon were seen. Total colectomy with ileostomy was performed. Postoperative course was marked by septicaemia and multi-organ failure followed by death. This case report emphasizes the importance of early diagnosis and treatment of acute FAC, and associated high mortality.

We present a case of fulminant amebic colitis in a human immunodeficiency virus (HIV)-infected homosexual man. The patient developed colonic perforation over a short time despite empirical therapy with metronidazole, and underwent right hemicolectomy. Amebic colitis was pathologically diagnosed by identifying invasive trophozoites of Entamoeba in a surgical specimen. Amebic colitis is one of the important differential diagnoses of acute abdomen in HIV-infected patients and/or homosexual men, especially in East Asia. Although fulminant amebic colitis is a rare manifestation of amebiasis, early diagnosis and treatment are thought to be important to improve the outcome of this highly fatal complication.

Fulminant necrotising amoebic colitis is a complication of untreated amoebiasis. This is seen in mainly low-income countries. It has a high mortality rate and is difficult to diagnose. We present an extremely rare case of fulminant necrotising amoebic colitis that caused diagnostic confusion in mimicking an acute abdomen, presumably caused by a perforated duodenal ulcer.

Amebiasis is still a major healthcare concern, especially in developing countries like Ecuador. The lack of sanitary control and hygiene measures make parasites infections still a burden for patients and physicians. Despite infections due to this parasites are usually mild, severe infections and fatal outcomes although rare still occur. Bowel perforation is a rare complication of amebiasis, and unfortunately, it continues to be almost fatal. We present a case of an Ecuadorian patient who presented to the emergency room with an acute abdomen, despite adequate surgery and critical care, the patient regrettably died. Bowel perforation due to Entamoeba histolytica was the final diagnosis.
