We evaluated the usefulness of the high-frequency ultrasound probe (HFUP, 20 MHz) to determine the depth of tumor invasion in 45 patients with superficial colorectal tumors. The correct diagnostic rate was 66% (30/45) when the depth of tumor invasion was classified into the following 6 layers: mucosa (m), upper 1/3 (sm1), middle 1/3 (sm2), and lower 1/3 (sm3) areas of the submucosa, muscularis propria (mp), and the subserosa or deeper areas (s). However, when the depth of tumor invasion was evaluated in 3 layers (m-sm1, sm2-sm3, and mp-deeper layer), which is the classification used to select cases for endoscopic mucosal resection, the correct diagnostic rate was 88.9% (40/45). These results suggest that the HFUP is useful to determine the depth of invasion to select treatment for superficial colorectal tumors.
我们评估了高频超声探头（HFUP，20MHz）在45例结直肠浅表肿瘤患者中确定肿瘤浸润深度的实用性。当肿瘤浸润深度分为以下6层时，正确诊断率为66%（30/45）：黏膜（m）、黏膜下层上1/3（sm1）、中1/3（sm2）和下1/3（sm3）区域、固有肌层（mp）以及浆膜下层或更深区域（s）。然而，当按照用于选择内镜黏膜切除术病例的分类方法将肿瘤浸润深度评估为3层（m-sm1、sm2-sm3和mp-更深层）时，正确诊断率为88.9%（40/45）。这些结果表明，高频超声探头对于确定浸润深度以选择结直肠浅表肿瘤的治疗方法是有用的。
