Abstract
The hemodynamics and treatment strategy of rectal varices were evaluated 19 cases that were treated in our hospital. The rectal varices were mainly supplied by the dilated inferior mesenteric vein (IMV). On the superior mesenteric arteriography and/or splenic arteriography, the backflow phenomenon of dilated IMV could be observed, and on the abdominal computer tomography (CT), the dilation of caliber of the IMV could be observed. 18 cases were treated with endoscopic therapy (sclerotherapy and/or band ligation) and one case with IMV-IVC shunt ligation. Although one case died rupture from the recurrent rectal varices and six cases required additional treatment, the other12 cases passed without additional treatment (mean followup period 30.6 months). In conclusion, 1) endoscopic therapy for the rectal varices was effective, convenient and safe, and it could be a standard treatment for the rectal varices excluding atypical cases, 2) CT with contrast medium was very useful to evaluate the hemodynamics and curative effects of the rectal varices.
