【摘要】：目的探讨经直肠超声(ERUS)术前评估直肠癌累及直肠系膜筋膜(MRF)的价值。方法 44例直肠癌患者术前均接受ERUS检查,其中18例接受新辅助放化疗,26例未接受;所有患者于接受ERUS检查后1周内行全直肠系膜切除手术(TME)。以术后病理诊断环周切缘(CRM)的结果为金标准,判断ERUS术前评估直肠癌累及MRF的诊断效能。结果 44例患者中,术后病理诊断T1期2例,T2期17例,T3期25例;CRM阳性2例,CRM阴性42例。低位直肠癌16例,中位直肠癌28例。肿瘤位于前壁和前侧壁26例,后壁和后侧壁13例,累及肠壁全周5例。ERUS对术前接受和未接受新辅助放化疗的患者诊断准确率分别为83.33%(15/18)和92.31%(24/26);肿物位于前壁和前侧壁时,诊断准确率为80.77%(21/26),而肿物位于后壁和后侧壁时为100%(13/13);对于低位和中位直肠癌,诊断准确率分别为75.00%(12/16)和96.43%(27/28);总准确率为88.64%(39/44)。结论 ERUS是术前评估直肠癌是否累及MRF的有效辅助检查方法。
[Abstract]:Objective to investigate the transrectal ultrasound (ERUS) in preoperative assessment of rectal cancer involving the mesorectal fascia (MRF) underwent ERUS examination value. Methods 44 cases of patients with rectal cancer before operation, among which 18 patients received neoadjuvant chemotherapy, 26 patients received; all patients to accept ERUS examination within 1 weeks after total mesorectal excision (TME) with the postoperative pathological diagnosis of circumferential resection margin (CRM) results as the gold standard, ERUS to determine the preoperative evaluation of rectal cancer involving the diagnostic efficacy of MRF. Results in 44 cases, postoperative pathological diagnosis of T1 2 cases, T2 17 cases, T3 25 cases; 2 cases were CRM positive, 42 cases of CRM negative. 16 cases of low rectal cancer, rectal cancer in 28 cases. The median anterior wall and anterior wall tumors in 26 cases, posterior wall and posterior wall in 13 cases, involving the whole intestinal wall in 5 cases of.ERUS patients received neoadjuvant chemotherapy diagnosis accuracy was 83.33% before operation (15/18) and 92.31% (24/26); the tumors located at the anterior and The front side wall, the diagnostic accuracy was 80.77% (21/26), and the tumor located in the posterior wall and posterior wall was 100% (13/13) for low rectal cancer; and the median, the diagnostic accuracy was 75% (12/16) and 96.43% (27/28); the total accuracy rate was 88.64% (39/44). Conclusion ERUS is an effective assessment auxiliary examination methods for preoperative rectal cancer whether involving MRF.
