摘要
目的:以前瞻性方式研究对比胆囊颈管结石(n=30)与胆囊体部结石(n=50)对胆总管直径的影响。材料和方法:对比两组胆总管超声内径和术中实测外径。结果:胆囊颈管结石组胆总管超声内径和术中实测外径(69mm,115mm)大于胆囊体结石组(47mm,82mm)。结论:胆囊颈管结石是胆总管轻度扩张的原因之一。
Puppose: This study was aimed at the effect of gallstone on diameter of common bile duct. Materials and Methods: The diameter of common bile duct was determined using ultrasound before and measured directly during operation in patients with gallbladder stones and with gallstone at cystic duct. Results: The results showed that both ultrosonic and measured diameter of group one (stone obstructs the cystic duct) was significantly larger than that of group two (stones located inside gallbladder). Conclusion: It was believed that stone which obstructed the cystic duct of gallbladder might be one factor causing enlargement of common bile duct.
