Abstract:
Objective To evaluate the applicant effect of improved flushing suction method for SpyClass choledochoscope operation. Methods Seventy-three patients who underwent SpyGlass choledocho-scopy from February 2013 to January 2015 were enrolled. Negative pressure biopsy channel was used in group A(n= 34)during conducting SpyGlass choledochoscopy with the tube directly connected to the conveying pipe and combined with duodenoscope suction.In group B(n= 39),the biopsy channel of disposable syringe jacket was first connected to a delivery catheter,then the negative pressure pipe was put in the injector coat, combined with duodenoscope suction. Adverse reactions,theⅠ image acquisition time after the placement of SpyGlass delivery catheter to pancreaticobiliary duct,the total operation time,and the occurrence of compli-cations after operation were recorded. Results Sinus bradycardia,arrhythmia,agitation occurred in 7 cases (20. 6%),5 cases( 14. 7%),and 10 cases( 29. 4%) respectively in group A,those were 1 case (2. 6%),0 case(0/ 39),2 cases(5. 1%)respectively in group B with significant difference(P<0. 05). The time to acquire a clear image and the total operation time in group A were 6. 2 min and 24. 9 min,and 3. 3 min and 16. 8 minutes in B group with significant difference(P<0. 05),postoperative cholangitis oc-curred in 5 cases in group A(14. 7%),1 case(2. 6%)in group B with significant difference(P<0. 05). Conclusion New irrigation and suction method has obvious advantages in the SpyGlass system.
