原发性骶前肿瘤的诊断与治疗

Diagnosis and Treatment of Primary Presacral Tumor

为探讨骶前肿瘤的诊断与治疗，分析了３７例骶前肿瘤的诊断和治疗情况。肿瘤直径３～１６ｃｍ。术前诊断主要依靠直肠指诊、Ｂ超、ＣＴ等相关检查。手术方法有：经骶尾部切除１５例，经腹切除１０例，经腹尾部联合入路切除６例。其中合并切除直肠４例，肿瘤完整切除２１例，部分切除１０例，未切除６例，切除率８３．８％。并发症有出血、直肠损伤、术后骶前感染、脓肿形成。作者认为合理选择手术径路、手术方式是切除肿瘤的关键。

To study the diagnosis and treatment of presacral tumor (PST), we analysed the clinical data of 37 patients with presacral tumors retrospectively. The mean diameter of the tumors was 10.2cm (ranged from 3 to 16cm). Clinical diagnosis was made mainly by routine digtal anal examination, ultrasound and CT scans. The operative ways included through sacrococcygeal position (15 cases), abdomen (10 cases) and combinated the two ways (6 cases). Combination of tumor and rectum resection was performed in 4 patients. The tumor was completely resected in 21, partially resected in 10, unable to be resected in 6. Tumor resective rate was 83.8 percent. Operative complications included haemorrhage, rectal injury, presacral abscess formation. The authors believe that the key point to resect tumor lies in a rational selection of operative way and type. Preoperative imaging examination was helpful to the location of tumor and choice of the operation type.
