CT引导置管引流治疗单发性腹膜后脓肿

CT guided percutaneous drainage in treatment of solitary retroperitoneai abscess

目的探讨单发性腹膜后脓肿CT引导下经皮穿刺置管引流治疗的疗效。方法回顾性总结采用CT引导下经皮穿刺引流治疗的13例腹膜后单发性脓肿,脓肿位于胰尾部4例,胰头旁3例,肾周间隙3例,肾后间隙2例,腰大肌旁1例;脓肿最大径3.5～8.0cm。结果8例患者行1次穿刺引流,3例行2次穿刺引流,2例行3次穿刺引流。13例患者平均引流16d,经过临床、超声及CT随访未发现残存感染灶或复发。结论CT引导下经皮穿刺引流治疗腹膜后脓肿疗效确切、创伤小。

Objective To evaluate the therapeutic efficacy of percutaneous drainage of solitary retroperitoneal abscess under CT guidance. Methods A retrospective analysis was made for percutaneous drainage of solitary retroperitoneal abscess with CT guidance in 13 patients including 4 at the tail of pancreas, 3 nearby the head of pancreas, 3 in perirenal space, 2 in posterior renal space and 1 case was by the side of psoas muscle. The maximum diameters of retroperitoneal abscess were between 3.5 cm and 8 cm. Results Out of 13 patients, 8 with one time drainage, 3 with twice drainages and 2 with thrice drainages. The mean duration of drainage was 16 days with no recurrence or residual lesions during clinical follow up. Conclusion CT guided percutaneous drainage of solitary retroperitoneal abscess is effective and minimally invasive.
