ABSTRACT

Objective: To present a series of ameboma cases handled along 38 years in a public hospital of Mexico City, Mexico.
Setting: Hospital General de México, Mexico City, Mexico.
Design: Retrospective, observational, transversal study.
Statistical analysis: Percentages as measure of qualitative variables.
Material and methods: All ameboma cases operated from January 1970 to December 2007 were included. Assessed variables were: age, gender, diagnostic certainty, surgical procedure, perioperative mortality, and evolution of this rare complication along the last four decades.
Results: From a total of 25 840 emergency abdominal surgeries and 129 cases of surgical procedures of the colon due to amebiasis, there were six cases of ameboma, four in men and two in women, average age of 42 years (range 37 to 55). All cases corresponded to the ascending colon, and were manifested by acute abdomen or intestinal occlusion symptoms, they were diagnosed and postoperatively confirmed through histopathological studies. Three cases occurred in the 70s and one case in each of the three subsequent studied decades. Surgery consisted of resection of the ascending colon with ileostomy due to suspicion of malignant colon tumor.
Conclusions: The ameboma is a very rare complication of invasive amebiasis and is, in most cases, confused with a neoplasia, giving rise to its ample surgical resection with oncological criteria.
