Abstract
The mucosa of free jejunal autoraft (FJG) was observed and the biopsies were obtained endoscopically in 24 patients operated on the pharyngeal and/or cervical eso-phageal carcinoma. The observation periods were within one year was 14 cases, from 1 to 3 years in 6 cases and over 3 years in 4 cases. The age ranged from 42 to 85. The results obtained were summarized as follows; The mucosal tissue blood flow of FJG was maintained constantly. The finger-shaped and leaf-shaped villi were most frequently observed in FJG and the mixed shape villi were observed in 25% of the patients. Villous height was significantly lower within one year and reached the constant level over one year and the width of villi was wider than the preoperative level within one year. Histologically, the stained zone of the mucin components did not change. It is concluded that, villous height and width show changes within one year and maintained the constant level there after.
