MPR重建CT引导下经皮腹膜后肿物穿刺活检术应用价值.

Objective To investigate the clinical value and safety of Multi-planner reformation (MPR) reconstruction and CT-guided percutaneous puncture biopsy of retroperitoneal masses. Methods A total of 79 patients who underwent percutaneous retroperitoneal of retroperitoneal masses from August 2019 to August 2022 in this hospital were retrospectively analyzed, including MPR reconstruction CT 44 cases (the MPR group) and 35 cases (the general group) guided by conventional axial CT. The success rates and complications of the two groups were compared. Results The success rate of puncture was 97.7% in the MPR group and 85.7% in the general group, and the difference between the two groups was statistically significant (P=0.045). Among the 73 patients with successful puncture, retroperitoneal masses were malignant lymphoma (39.7%), metastatic tumor (43.8%), schlemma (5.5%) and lymph node tuberculosis (11.0%). The incidence of complications was 20.5% in the MPR group and 45.7% in the general group, and the difference between the two groups was statistically significant (P=0.016). Conclusion MPR reconstruction and CT-guided percutaneous puncture biopsy of retroperitoneal masses is safe and reliable, which can improve the success rate and reduce the incidence of complications compared with general CT-guided puncture, and is worthy of clinical promotion.
