胆囊切除术后再发肝内胆管结石的临床研究

The clinic study of recurrent hepatolithiasis afer cholecystectomy

目的探讨胆囊切除术后再发肝内胆管结石的病因及预防措施。方法回顾性分析206例行手术治疗的原发性肝内胆管结石患者的临床资料,调查既往行胆囊切除术的情况,计算胆囊切除术后再发肝内胆管结石患者占原发性肝内胆管结石患者中的比例。结果胆囊切除术后再发肝内胆管结石患者27例,占13.1%,与原发性肝内胆管结石患者相比,其性别、年龄分布无差别。行胆囊切除术时间与再发肝内胆管结石的平均时间间隔为(15.4±7.6)a。结论胆囊切除术后再发肝内胆管结石的发生可能与手术时机、手术操作等相关,更可能与胆囊结石形成时已经存在的成石条件有关。

Objective To study the preventive measure and the etiology of recurrent hepatolithiasis complicated by Cholecystectomy.Methods The clinical data of 206 patients of hepatolithiasis were retrospectively analyzed.To investigate whether they underwent cholecystectomy and calculate the propo rtion of the recurrent hepatolithiasis after the operation.Results 27of 206（13.1%） patients had already undergone cholecytectomy.The distributions of sex and age of these patients are no differences.The mean interval between cholecystectomy and recurrent hepatolithiasis is 15.4±7.6 years.Conclusion The reason of recurrent hepatolithiasis afer cholecystectomy is not only the time and the operation of cholecystectomy itself,but also the conditions already existed when the gallbladder stones were formed.
