Schistosomal colonic disease.

Abstract

This study evaluates 216 patients with schistosomal colonic disease, diagnosed by endoscopic biopsies at the Armed Forces Hospital, Riyadh. The colonoscopic appearance was suggestive of schistosomiasis in 98 of these patients (45.37%), Schistosoma mansoni ova in stool was detected in only 24 of these 216 patients (11-11%). The most common histopathological finding in colonic biopsies of these patients was Schistosoma mansoni ova in the colonic mucosa with no or mild inflammatory celis infiltrates. These findings correlate with the endoscopic appearances in most

Hypertensive portal colopathy in schistosomiasis mansoni: proposal for a classification

“…While vascular lesions in the colonic mucosa of cirrhotic patients with portal hypertension have been reported (Kosareck et al 1991, Viggiano & Gostout 1992, Rabinovitz et al 1995, Chen et al 1996, Ganguly et al 1995, Misra et al 1996, Bresci et al 1998, Bini et al 2000, studies on hepatosplenic schistosomiasis mansoni are scarce (Mohamed et al 1990, Sanguino et al 1993, Geboes et al 1995.…”

“…For ethical reasons, we did not study patients without prior episode of upper or lower gastrointestinal bleeding and the patients selected had already been treated for schistosomiasis to avoid the alterations due to the parasitose per si (Pereira 1962, Mohamed et al 1990, Sanguino et al 1993, Geboes et al 1995.…”

“…Alterations in the colonic mucosa caused by Schistosoma mansoni eggs are described as increased vascular bed, edema, congestion, scattered petechial spots with the aspect of "flea-bites", ulceration, and polyps (Pereira 1962, Mohamed et al 1990, Sanguino et al 1993. Considerable controversy still exists regarding the colonic abnormalities in patients with portal hypertension due to schistosomiasis mansoni (Mohamed et al 1990, Sanguino et al 1993, Geboes et al 1995.…”

“…Considerable controversy still exists regarding the colonic abnormalities in patients with portal hypertension due to schistosomiasis mansoni (Mohamed et al 1990, Sanguino et al 1993, Geboes et al 1995.…”

Colonic polyps in hepatosplenic schistosomiasis mansoni

“…There was hepatosplenomegaly. The hemoglobin was 15.4g/dl, total leukocyte count of 4,500/ mm 3 , and with 68,900 platelets. Stool examination was negative for eggs of S. mansoni.…”
