Colonic mucosal changes in patients with liver cirrhosis

Clinicopathological Evaluation Of Portal Hypertensive Colopathy In Cirrhotic Patients

“…The prevalence of PHC in patients with cirrhosis varies from 25% to 85% in various studies. [7][8][9][10][11] In the present study, portal hypertensive colopathy was observed in 61% (61/100 patients). Portal hypertensive colopathy was found in caecum and Ascending colon in 14 patients, transverse colon in 12, Descending and Sigmoid colon in 10 and rectum in 64 patients.…”

Hypertensive portal colopathy in schistosomiasis mansoni: proposal for a classification

“…This can be explained by the chronic increase of the intraluminal pressure (Misra et al 1997). Endoscopic biopsies of the vascular lesions in the colonic mucosa were avoided due to the high risk of bleeding (Tam et al 1995). However, when it is obtained, the descriptions include dilatation and tortuosity of the mucosa vessels, as well as an increase in the number of small vessels and the wall thickness in the lamina propria (Viggiano & Gostout 1992).…”

“…During the examination, they received an intravenous sedation of meperidine associated with midazolan, monitored through pulse oximetry. In accordance to criteria described by Tam et al (1995), the lesions were characterized as: erythemas (diffuse hyperemia in the mucosa), red spots (hyperemic focus in the mucosa), telangiectasia (dilated and tortuous small vessels), angiodysplasia (coiled vessels measuring about 1 cm), rectal varices (dilated, crooked vessel). The current authors elaborated a classification for the colopathy in patients with schistosomiasis and portal hypertension, based on both literature concerning cirrhotic patients and personal experience.…”

Improvement of Schistosomal Portal Hypertensive Colopathy After Surgical Treatment

“…It was done using a conventional resolution videocolonoscope (Olympus CF-140, Tokyo, Japan.) Colonic mucosal vascular lesions at endoscopy were classified according to the criteria of Tam et al (18) , as follows: erythema (diffuse hyperemic mucosa), telangiectasia (tortuosity and engorgement of small vessels), angiodysplasia (coiled vessels measuring about 1 cm), and red spots (hyperemic focus in the mucosa). Rectal varices were evaluated according to the criteria laid down by The Japanese Research Society (19) , i.e.…”
