To assess gallbladder (GB) volume variations in response to a standard meal.
We assessed these variations with ultrasonography at brief intervals over the postprandial period, which included the emptying and refilling phases of the GB.
During both emptying and refilling of the GB, the volume fluctuated continuously, with brief alternating volume decrements and increments. The phases of emptying and refilling appear to be the net result of the algebraic sum of these volume fluctuations. In the emptying phase, the volume decrements showed a greater volume (35.7 +/- 10.7 ml vs. 14.8 +/- 8.4 ml) and lasted longer (158 +/- 37 min vs. 85 +/- 44 min) than the volume increments, whereas the opposite took place in the refilling phase (4.3 +/- 3.4 ml vs. 16.4 +/- 12.2 ml; 39 +/- 20 min vs. 84 +/- 37 min).
It is probable that the continuous GB volume fluctuations are the expression of hepatic bile recycling in the GB during the entire postprandial period, and the amount of bile recycled by the GB is greater during the emptying than the refilling phase.
评估胆囊（GB）容积对标准餐的反应变化。
我们在餐后短时间间隔内用超声检查评估这些变化，其中包括胆囊的排空和再充盈阶段。
在胆囊排空和再充盈过程中，容积持续波动，有短暂的交替性容积减少和增加。排空和再充盈阶段似乎是这些容积波动代数和的最终结果。在排空阶段，容积减少的幅度更大（35.7±10.7 ml对14.8±8.4 ml），持续时间更长（158±37分钟对85±44分钟），而容积增加的情况则相反，在再充盈阶段（4.3±3.4 ml对16.4±12.2 ml；39±20分钟对84±37分钟）。
整个餐后期间胆囊容积持续波动很可能是胆囊内肝胆汁循环的表现，且胆囊在排空阶段回收的胆汁量比再充盈阶段更多。
