[The layers of the gallbladder wall: an ultrasound-anatomic comparative study].
In a sonographic-histological comparative test, operatively withdrawn gallbladders in native and formol-fixed states were examined. The thickness of the gallbladder wall and of its layers was measured sonographically. Afterwards the gallbladders were reexamined microscopically in the sonographic sectional plane and the measurement was repeated. By removal of the single layers of the wall and by repeated sonographic measuring, sonographic and microscopic measurements of the parietal layers could be correlated. Both gallbladder wall thickness and thickness of the single anatomic layers can be evaluated sonographically. The correlation between sonographic and histological measurements is fairly to highly significant. The sonographically measurable layers can be related to the following anatomical layers (when measuring from outwards to inwards): 1. echogenic layer = initial echo and subserosa; 2. echo-poor layer = muscularis; 3. echogenic layer = lamina propria; 4. echo-poor layer = mucosal epithelium; 5. echogenic layer = exit echo.
