  • Title: [Amebiasis. Surgical treatment in 1989].
    Author: Sigler Morales L, Mier y Díaz J, Melgoza Ortiz C, Blanco Benavides R, Medina González E.
    Journal: Rev Gastroenterol Mex; 1989; 54(3):185-9. PubMed ID: 2682975.
    Abstract:
    Even when the number of patients with invasive amebiasis has decreased, the internist and surgeon must be alert in case that the patient requires an operation. Amebic liver abscess is treated medically; percutaneous evacuation is rarely used and surgical drainage is made when there is not response to medical treatment or there is high risk of abscess rupture. Operation is mandatory when the abscess has ruptured to the abdominal cavity or through the pericardial sac. In fulminant colitis it is necessary to resect the diseased portion of the colon without primary anastomoses. Amebic apendicitis is difficult to diagnosis before an operation. It may be suspected in cases of apendicitis if the cecal wall is inflammed. Colon ameboma requires medical treatment except if it is associated with necrosis or perforation. In a four year period (1985-1988) 294 patients with diagnosis of invasive amebiasis were admitted to three hospitals of the Instituto Mexicano del Seguro Social in Mexico City. 218 had hepatic abscess, 45 required surgical drainage with four deaths (9%) and four not operated patients died. In this series only four patients had their abscess drained percutaneously. 31 patients with amebic colitis were treated; three required colonic resection with one death. Ameboma was seen in five patients and there were 11 cases of amebic apendicitis. No deaths occurred in these last two groups.
