GALLSTONES AND GALLBLADDER DISORDER AFTER GASTRECTOMY FOR GASTRIC-CANCER

The incidence of gallbladder diseases, in particular of gallstones, wa s investigated in 268 cases during follow-np after resection of a gast ric cancer, Factors investigated for correlation with any incidence in cluded the extent of gastrectomy, reconstruction, and the degree of ly mph node dissection, Moreover, in 20 of these, the contractile functio n test using a cerulein injection was performed, while in a further 6 cases, a sequential contractile function test with fatty meal was perf ormed, The incidence of gallstones was 10.5% after total gastrectomy, 12.4% after distal gastrectomy, Debris was found in a further 6.7% aft er total gastrectomy and in 1.2% after distal gastrectomy, There was n o difference in the incidence of gallstones among the reconstruction m ethods, With respect to lymph node dissection, the incidence of gallst one formation was 16.3% after D3 and 8.5% after D2-1. In the contracti le function test, although the basal area was significantly larger aft er D3 than after D2-1, there was no difference in the contractile rate , The sequential contractile function test showed a peak contraction a t 15 minutes after feeding,vith gradual refilling in both those after D3 and those after D2-1.
