目的

探讨可分离式系线磁控胶囊内镜(ds-MCE)技术对于十二指肠乳头的检出率,通过观察十二指肠乳头形态,预测内镜下逆行胰胆管造影术(ERCP)时胆管插管风险。

方法

选取2022年1月至2022年10月经遵义医科大学第五附属(珠海)医院收治的20例ERCP术前完善ds-MCE检查患者为研究对象,对20例行ds-MCE检查患者的十二指肠乳头检出率进行回顾分析。分析此检查对于十二指肠乳头的检出率并观察其乳头形态,预测选择性胆管插管风险。

结果

ds-MCE十二指肠乳头的检出率为70%(14/20);形态I型11例、IV型3例;均行ERCP,选择性插管良好,平均时间为2.93 min,未出现术后胰腺炎(PEP)及高淀粉酶血症。

结论

ds-MCE可以提高十二指肠乳头的检出率,并可进一步观察乳头形态预测ERCP时胆管插管风险。

Objective

To investigate the detection rate of the duodenal papilla using detachable string magnetically controlled capsule endoscopy technology, and to predict the risk of bile duct intubation during endoscopic retrograde cholangiopancreatography (ERCP) by observing the morphology of the duodenal papilla.

Methods

A retrospective analysis was conducted on the detection rate of duodenal papilla in 20 patients who underwent ERCP with complete ds-MCE examination before surgery and were admitted to the Fifth Affiliated Hospital of Zunyi Medical University(Zhuhai)from January 2022 to October 2022. Analyze the detection rate of duodenal papilla by this examination and observe its papilla morphology to predict the risk of selective biliary catheterization.

Results

The detection rate of ds-MCE duodenal papilla was 70% (14/20); 11 cases of Type I and 3 cases of Type IV morphology; All patients underwent ERCP, with good selective intubation and an average time of 2.93 minutes.No postoperative pancreatitis or hyperamylasemia occurred.

Conclusion

ds-MCE can improve the detection rate of duodenal papilla and further observe papilla morphology to predict the risk of bile duct catheterization during ERCP.
