Abstract:
Objective To evaluate the value of intra-biliary contrast-enhanced ultrasound (IB-CEUS) in percutaneous transhepatic cholangial drainage (PTCD).
Methods A retrospective analysis was conducted on 210 patients with biliary obstruction who underwent ultrasound-guided PTCD at Ningbo Second Hospital from January 2020 to July 2021. The patients were divided into a control group (101 cases) and a contrast group (109 cases) based on whether IB-CEUS was performed. The differences in surgical success rate, incidence of complications, and efficacy in treating jaundice were compared between the two groups by the chi-square test.
Results The success rate was 100% in both groups. The total incidence of postoperative complications in the contrast group was 8.3% (9/109), slightly higher than that of the control group (5.0%, 5/101), but there was no statistically significant difference between the two groups (P>0.05). In terms of efficacy, there were 3 cases (2.8%, 3/109) of ineffectiveness in reducing jaundice in the contrast group, and 15 cases (14.9%, 15/101) in the control group. The contrast group had significantly better efficacy in reducing jaundice than the control group (χ2=10.29, P=0.006).
Conclusion The use of IB-CEUS during PTCD surgery can guide drainage strategies and achieve better efficacy in reducing jaundice.
