Purpose: An increased incidence of gallstones has been widely reported in patients who had undergone a gastrectomy. But, there has been little information about the pathophysiologic mechanism for the occurrence of gallstones after gastric surgery. Many investigators have considered the cause to be decreased gallbladder motility due to vagal denervation. We observed higher increase in the incidence of gallbladder stones in patients who underwent a Billroth II gastrojejunostomy than in those who underwent a Billroth I gastrojejunostomy after radical subtotal gastrectomy.
Methods: We prospectively studied the change in the motility of the gallbladder after a gastrectomy. The gallbladder ejection fraction (EF) was compared pre- and postoperatively by using gallbladder scintigraphy with 2,6-diisopropyl-iminodiacetic acid (DISIDA).
Results: Twenty patients underwent a Billroth(B) I anastomosis and twelve patients underwent a B-II anastmosis after the gastrectomy. The means of the EF of the B-I group were 75.9%, 46.4%, 68.1% at the preoperative period, at 1 month and 6 months after the gastrectomy respectively. Those of B-II group were 78.2%, 45.3%, 56.3%, respectively. There was no statistically significant difference of EF between the two groups at postoperative 1 month, but the difference at postoperative 6months was statistically significant. The differences of EF between preoperative period and postoperative 1 month, 6 months were significant in the B-I group and the B-II group.
Conclusion: At 6 months postoperative period, there was more recovered gallbladder motility after a gastrectomy with B-I anastomosis than with B-II anastomosis.
