Normal neuronal features of the human gallbladder and structural changes in cholelithiasis patients

Report on a histological study of ten gallbladders, of which five were from normal subjects and five from patients with cholelithiasis. In normal controls a higher number of nerve cells was found in the neck (23.45 +/- 10.14 per mm2) and a lesser one in the body (7.70 +/- 8.45 per mm2) and fundus (5.60 +/- 3.66 per mm2). In the lithiasic gallbladder wall the higher number of the nerve cells was present in the neck (5.83 +/- 4.92 per mm2), and a lowest one in the body (2.63 +/- 1.56 per mm2) and fundus (1.03 +/- 0.71 per mm2).
