肝脏肿瘤的腹腔镜超声检查和活检术:310例经验

目的探讨腹腔镜超声肝脏检查及在其引导下肝脏肿瘤穿刺活检术的价值. 方法 10 mm 7.5 MHz线性超声探头检查肝脏.18G穿刺针进行穿刺.在腹腔镜和超声波共同引导下,穿刺针经皮刺入肿瘤组织.穿刺时,穿刺针要与超声波的平面平行. 结果 310例发现肝脏原发或转移性肿瘤1 080个.穿刺无一例假阴性,无出血性并发症及其他脏器损伤.310例随访6年,穿刺点无肿瘤种植. 结论腹腔镜超声波检查能较准确对肝脏进行全面评估,在其引导下细针穿刺活检术可行.

Laparoscopic ultrasonography and biopsy of hepatic tumors in 310 patients

Objective To describe the technical aspects of ultrasonic imaging and biopsy of hepatic tumors. Methods A 10 mm 7.5 MHz linear, side viewing laparoscopic ultrasonography probe was used for imaging, and an 18G spring-loaded core biopsy gun was used for tissue diagnosis. The biopsy needle was introduced percutaneously into the tumor under the guidance of laparoscopy and ultrasonography. Needle was best targeted into the lesion when inserted parallel to the plane of the transducer. Results A total of 1 080 primary or metastatic liver tumors were found in 310 patients. There were no false negatives. No hemorrhagic complications or injuries of other organs occurred. The patients were followed up with liver CT scans for 6 years, and no evidence of needle tract seeding was identified. Conclusions Imagining and biopsy under the laparoscopic ultrasonography can evaluate the entire liver accurately and are feasible and practicable.
