主 题：Chronic Liver Disease Lymphangiogenesis Microsurgery Collateral LymphaticCirculation
摘 要：The splanchnic inflammation inchronic liver disease increases intestinal angiogenesis. In the current study our aim was demonstrating that the small bowel lymphangiogenesis is associated with angiogenesis in chronic cholestasis in the rat. A stereological study of the lymphatic microcirculation in the small intestine was performed in cholestatic rats. Portal enteropathy in cholestasis increases lymphatic microvessels in the mucosa and submucosa layers. Thus, the lymphatic microvessel volume fraction was superior (p 0.001) in the mucosa (0.16 ± 0.01) and submucosa (0.16 ± 0.01), in regard to the muscle layer 0.015 ± 0.01. The lymphatic microvessel length density was higher in the mucosa (76.89 ± 2.86 mm-2;p -2;p 0.01), in relationship to the muscle layer (5.04 ± 2.92 mm-2). These alterations predominate in the duodenum (volume fraction: 0.10 ± 0.01 and length density: 33.55 ± 5.98 mm-2) and ileum (volume fraction: 0.16 ± 0.01 and length density: 38.62 ± 6.07 mm-2). This study demonstrates the predominance of an increased lymphangiogenic response in both end sides of the small bowel associated with chronic liver disease. Since the porto-systemic venous collateral circulation in the chronic liver insufficiency is developed in the ends of the gastrointestinal tract, the excessive duodeno-ileal lymphangiogenesis could suggest the development of amesenteric-systemic lymphatic bypass in the chronic portal hypertension.
