【摘要】：目的探討經(jīng)直腸超聲(ERUS)術(shù)前評估直腸癌累及直腸系膜筋膜(MRF)的價值。方法 44例直腸癌患者術(shù)前均接受ERUS檢查,其中18例接受新輔助放化療,26例未接受;所有患者于接受ERUS檢查后1周內(nèi)行全直腸系膜切除手術(shù)(TME)。以術(shù)后病理診斷環(huán)周切緣(CRM)的結(jié)果為金標(biāo)準(zhǔn),判斷ERUS術(shù)前評估直腸癌累及MRF的診斷效能。結(jié)果 44例患者中,術(shù)后病理診斷T1期2例,T2期17例,T3期25例;CRM陽性2例,CRM陰性42例。低位直腸癌16例,中位直腸癌28例。腫瘤位于前壁和前側(cè)壁26例,后壁和后側(cè)壁13例,累及腸壁全周5例。ERUS對術(shù)前接受和未接受新輔助放化療的患者診斷準(zhǔn)確率分別為83.33%(15/18)和92.31%(24/26);腫物位于前壁和前側(cè)壁時,診斷準(zhǔn)確率為80.77%(21/26),而腫物位于后壁和后側(cè)壁時為100%(13/13);對于低位和中位直腸癌,診斷準(zhǔn)確率分別為75.00%(12/16)和96.43%(27/28);總準(zhǔn)確率為88.64%(39/44)。結(jié)論 ERUS是術(shù)前評估直腸癌是否累及MRF的有效輔助檢查方法。
[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.
