总结骶前发育性囊肿的临床特点及探讨经骶尾入路手术的治疗效果。

回顾性分析中山大学附属第六医院于2007年8月至2016年8月经骶尾入路手术治疗的43例骶前发育性囊肿患者的临床资料。

本次研究中，男性4例，女性39例，临床症状不典型，在最终确诊前有16例患者曾被误诊。手术治疗均采用经骶尾入路，手术时间为（125±43）min，术中出血量为（157±56）ml，术中32例患者切除尾骨，4例患者切除部分骶骨及尾骨。术后伤口感染2例（4.6%）。术后病理结果：尾肠囊肿15例，表皮样囊肿9例，畸胎瘤14例，皮样囊肿4例，恶性畸胎癌1例。术后所有患者均获得随访，平均随访时间45（6~74）月，有1例患者复发，复发率2.3%。

骶前发育性囊肿患者症状不典型，初诊时易被误诊，经骶尾入路手术可以治疗大多数骶前发育性囊肿，手术创伤小，出血少，明显降低了术后的并发症。

To summarize the clinical features of presacral developmental cysts and investigate the therapeutic effect of transsacrococcygeal approach.

Clinical data of 43 patients with presacral developmental cysts underwent transsacrococcygeal approach from August 2007 to August 2016 was retrospectively analyzed.

In this group, four male and 39 female patients were included. The clinical presentations were nonspecific and sixteen patients were misdiagnosed before the correct diagnosis was made. All patients were treated with tanssacrococcygeal approach. The operative duration was (125±43) min and the blood loss of each operative approach was (157±56) ml. Coccygectomy was performed in 32 patients and partial sacral resection was performed in four patients. The surgical incision infection occurred in two patients (4.6%). Postoperative pathological findings: fifteen patients had tailgut cysts, nine patients had epidermoid cysts, fourteen patients had teratomas, four patients had dermoid cysts and one patient had malignant teratocarcinoma. The patients were followed up for 6~74 months (mean, 45 months) and the tumor relapsed in one patient (2.3%).

The clinical presentations were nonspecific and patients with presacral developmental cysts were easily misdiagnosed at first visit. Transsacrococcygeal approach can be used to manage majority of presacral developmental cysts with less blood loss and lower complication rate.
