目的:本文旨在探讨直肠腔内B超扫描在术前分期,判断局部浸润和淋巴扩散中的价值。方法:采用日本Aloka-SSD-20型实时超声显像仪,棒状单平面7.5MHz探头对100例直肠肿瘤进行术前直肠腔内扫描。结果:在13例直肠腺瘤中对局部浸润深度的诊断全部正确。87例直肠癌中对局部浸润深度的诊断正确率为82.76%。故全组对局部浸润深度的诊断正确率为85%。对肠外淋巴结受累的诊断正确率为75%。对邻近器官受累的诊断正确率为100%。结论:腔内B超扫描作为一项术前辅助诊断措施,具有方便、安全、无创伤、无痛苦及正确率高等特点。
Objective: This article aims to investigate the value of rectal cavity B-scan in preoperative staging and judging local infiltration and lymphatic spread. METHODS: Preoperative rectal endotracheal scanning was performed on 100 rectal tumors using a Japanese Aloka-SSD-20 real-time ultrasound imaging system and a rod-shaped monoplane 7.5 MHz probe. Results: In 13 cases of rectal adenoma, the diagnosis of local infiltration depth was correct. The diagnostic accuracy of local infiltration depth in 87 cases of rectal cancer was 82.76%. Therefore, the accuracy of diagnosis of local infiltration depth in the whole group was 85%. The diagnostic accuracy of the involvement of the parenteral lymph nodes is 75%. The diagnostic accuracy of the involvement of adjacent organs is 100%. Conclusion: Intraluminal ultrasound scanning as a preoperative auxiliary diagnostic measure is convenient, safe, non-invasive, painless, and high in accuracy.
