KOTZE, Paulo Gustavo et al. Myiasis larvae in rectal prolapse: case report and review of the literature. Rev bras. colo-proctol. [online]. 2009, vol.29, n.3, pp.382-385. ISSN 0101-9880. http://dx.doi.org/10.1590/S0101-98802009000300014.
INTRODUCTION: myiasis is an infection of human tissues with dipterous fly larvae. It is commonly located in human skin, however, it is described in natural orifices. This condition is treated by mechanical extraction of larvae associated with damaged tissue ressection. OBJECTIVE: case report of a patient with myiasis infection of rectal prolapse, emphasizing its incidence, symptoms and treatment options. CASE REPORT: L.C.S., a 36-year-old male, with rectal prolapse complaints for one year, with bad sanitary conditions. Proctological examination revealed rectal prolapsed with necrosis areas affected by myiasis. Larvae remotion was realized with necrotic tissue resection. A loop-sigmoid colostomy was performed due to extensive perineal wound and internal sphincter damage. CONCLUSIONS: rectal prolapse with myiasis infection is rare, and must have prompt diagnosis and treatment. A simple perineal examination is essential. We emphasize continous health education and basic hygiene measures for the population.
