摘要

目的：

探讨经直肠超声(transrectal ultrasonography，TRUS)对直肠类癌的诊断及辅助经肛门内镜微创手术(transanal endoscopic microsurgery，TEM)的价值。

方法：

选取2015年1月2016年12月入该院诊治并获得明确病理结果的直肠隆起性病变患者65例，所有患者术前均接受了结肠镜、TRUS和小探头超声内镜(miniprobe sonography，MPS)检查。总结直肠类癌的经直肠超声影像学特征，并比较结肠镜、TRUS、MPS对直肠类癌的诊断准确率。应用TRUS对上述类癌患者行TEM术前定位、术后并发症筛查和随访。

结果：

直肠类癌的TRUS影像学特征表现为黏膜下层的类圆形、低回声、富血供结节，边清，内部回声均匀；TRUS对直肠类癌有较高的诊断准确率(96.9%)，与MPS(95.4%)比较差异无统计学意义(

＞0.05)，优于结肠镜(81.5%)(

＜0.05)。TRUS对直肠类癌TEM的术前定位、术后并发症的发现和随访有重要应用价值。

结论：

TRUS对直肠类癌具有较高的诊断价值，可媲美MPS，可作为辅助TEM手术的首选影像学检查方法。

Abstract

Objective:

To explore the value of transrectal ultrasonography (TRUS) in the diagnosis of rectal carcinoid and assisted transanal endoscopic microsurgery (TEM).

Methods:

Between January 2015 and December 2016

the data of 65 patients with rectal protuberant lesions were collected. Miniprobe sonography (MPS)

colonoscopy

TRUS and pathologic examinations were performed. The TRUS images of rectal carcinoid confirmed by pathology were analyzed to find out the characteristics. The accuracies of colonoscopy

TRUS and MPS in diagnosing rectal

carcinoid were compared. TRUS was applied to localize the lesions before TEM

discover the postoperative surgical complications and follow up.

Results:

The TRUS characteristics of rectal carcinoid includes well-defined boundary

homogeneous echo

hypoechoic nodules with rich blood supply in the submucosa. TRUS had a highaccuracy rate of 96.9% in the diagnosis of rectal carcinoid

similar with MPS (95.4%)

and superior to colonoscopy (81.5%). TRUS was of great value in the preoperative localization of rectal carcinoid

the detection of postoperative complications and follow up.

Conclusion:

TRUS has a high diagnostic value for rectal carcinoid

as good as MPS

and can be used as the first-choice imaging method for TEM.
