小肠自体移植完全阻断小肠的淋巴引流,也切断来自系膜和肠壁的神经支配,这些改变可能严重影响肠道的生理功能。研究旨在确定空回肠去神经后对空肠襻水、电解质、葡萄糖和叶酸盐净吸收的作用。犬分两组每组6条。A组(对照组,神经完整):取80cm空肠作改良的Thiry-Vella近端空肠襻,在保留的近端空肠和游离空肠襻间作2cm宽4cm长的无粘膜肌
Autotransplantation of the small intestine completely blocks the lymphatic drainage of the small intestine and also severs the innervation of the mesentery and the intestinal wall, and these changes may seriously affect the intestinal physiological function. The aim of the study was to determine the effect of empty ileum denervation on the net absorption of jejunum water, electrolytes, glucose and folate. Dogs divided into two groups of 6 each. Group A (control group, neurologically intact): 80 cm jejunum was used as the modified Thiry-Vella proximal jejunum, and 2 cm wide and 4 cm long mucosal muscle was reserved between the retained proximal jejunum and the free jejunum
