JEJUNAL MUCOSAL APPEARANCES IN THE ρ-SHAPED ANASTOMOSIS PATIENTS AFTER TOTAL GASTRECTOMY: STUDIES USING DISSECTING MICROSCOPE AND HISTOLOGICAL METHODS

Jejunal biopsies from 14 patients with ρ-shaped anastomosis after total gastrectomy (postoperative group) were examined and compared with specimens from 28 control subjects for a purpose of studying changes of jejunal mucosal appearances after total gastrectomy. A dissecting microscope and histological methods were used.
Dissecting microscopy showed that the villi numbered 9.7±1.8 per square millimeter in the postoperative group and 21.2±3.8 in the control group. In the postoperative group, finger-shaped villi were found in 10.1±7.8% and leaf-shaped villi 84.2±8.5% ; while, in the control group, they were 25.7±16.0% and 67.1±15.1% respectively. According to the classification of the predominant villous shape, which Scott et al. postulated, mucosal appearances were categolzed into “subnoml” villous pattern.
Histological examination showed that the height of the villi was 524±87μm in the control group and diminished to 307±57μm in the postoperative group. Normal height of.the villi was found in 57% and partial villous atrophy in 43% of the postoperative group. Inflammatory findings in the lamina propria were of edema, small cell infiltration, congestion and lymphangioectasis: but no irreversible changes as fibrosis were seen.
These studies pointed out that jejunal mucosal changes in the ρ-shaped anastomosis patients were minor at the most.
