ERCP术后胆管支架置入对结石复发的影响

Effect of bile duct stent placement after ERCP on the recurrence of calculus

目的研究经内镜逆行性胰胆管造影术后胆总管结石的复发情况,评价胆管塑料支架对胆总管结石复发率的影响。方法回顾性分析收治的118例胆总管结石患者的临床资料,按照术式分为胆管支架组和鼻胆管组,比较2组患者的性别、年龄、结石数量等指标有无统计学差异,通过电话随访、制订问卷等方式了解患者结石首次复发情况。结果 2组患者在性别、年龄、结石数量等指标比较差异均无统计学意义(P>0.05);胆管支架组患者复发率为24.59%,鼻胆管组复发率为10.53%,放置胆管支架术后结石复发率高于鼻胆管组(P<0.05)。结论胆管塑料支架置入术后结石复发率要高于鼻胆管引流组。

Objective To study the recurrence of choledocholithiasis after endoscopic retrograde cholangiopancreatography(ERCP) and to evaluate the effect of plastic stents on the recurrence rate of choledocholithiasis.Methods The clinical data of 118 patients with choledocholithiasis admitted were retrospectively analyzed. They were divided into the biliary duct stent group and nasobiliary duct group according to the surgical procedure, and the age, gender and the number of stones in the two groups were compared. The follow-up by telephone and the formulating questionnaires were used to understand the first recurrence of stones.Results There was no significant difference between the two groups in gender, age, the number of stones and other indicators(P>0.05). The recurrence rate of the biliary duct stent group was 24.59%,the recurrence rate of the nasobiliary duct group was 10.53%,and the stones recurred rate after biliary stent placement was higher than that of the nasobiliary duct group, and the difference was statistically significant(P<0.05).Conclusion The recurrence rate of calculus after biliary plastic stent placement is higher than that of the nasobiliary drainage group.
