Gallbladder volume and contraction after a fatty meal was determined in 14 patients with gastric cancer before and 3-4 months after gastrectomy (7 total and 7 subtotal gastrectomies) with Roux-en-Y anastomosis. All patients had an increased gallbladder resting volume (p less than 0.001) and 10 of 14 patients (6 after total gastrectomy and 4 after subtotal gastrectomy) had an increased minimal residual volume after fatty meal stimulation (p less than 0.01) in the postoperative state, when compared to the preoperative values. It can be concluded that gastrectomy is followed by an impairment of gallbladder tone and contraction, both possibly increasing the risk of gallstone formation.
对14例胃癌患者在胃切除术前以及胃切除（7例全胃切除和7例次全胃切除）并采用Roux-en-Y吻合术3 - 4个月后测定其进食脂肪餐后的胆囊容积及收缩情况。与术前值相比，所有患者术后胆囊静息容积均增加（p < 0.001），14例患者中有10例（全胃切除术后6例，次全胃切除术后4例）在进食脂肪餐刺激后最小残余容积增加（p < 0.01）。可以得出结论，胃切除术后胆囊张力和收缩功能受损，这两者都可能增加胆结石形成的风险。
