ATIK, Fernando Antibas et al. Large intestine obstruction complicated with perforation: a rare manifestation of Schistosoma mansoni infection. Sao Paulo Med. J. [online]. 1998, vol.116, n.4, pp. 1781-1783. ISSN 1806-9460. http://dx.doi.org/10.1590/S1516-31801998000400008.
The authors report a case of a 25 year old Brazilian man with a history of crampy abdominal pain in the left iliac fossa for 2 weeks, abdominal distention, mucous diarrhea and anorexia. The patient presented signs of hemodynamic instability and a hard mass palpated in the left iliac fossa presented peritoneal irritation. At laparotomy, fecal peritonitis and a punched-out perforation of the midsigmoid colon were found. A left hemicolectomy was performed with terminal colostomy. Specimen examination revealed a thickened rectosigmoid wall, narrow lumen and multiple mucosal polyps. Microscopically, chronic granulomatous colitis with Schistosoma mansoni eggs confirmed the etiology. To the authors' knowledge, this is the first case of obstruction complicated with perforation due to mansoni schistosomiasis reported in the literature.
