背景：由于胃肠道肿瘤通常是坚硬的，因此在手术中可以通过触摸来评估肿瘤的存在和范围。然而，不存在用于评价组织硬度的客观尺度。我们开发了一种新的仪器，内窥镜超声触觉传感器，可以客观地评估硬度。在这项研究中的有用性，该设备用于诊断胃癌的程度evaluated.Methods：23例患者的抑郁症或溃疡的早期胃癌和7例患者的活动性或愈合的胃溃疡进行内镜检查与超声触觉传感器胃切除术前。胃癌的组织学类型和溃疡的存在并不影响肿瘤硬度和粘膜癌不能区分粘膜下或更深cancer.Conclusions：这种新的超声触觉传感器是有用的内镜诊断胃癌的程度。
Background: Because gastrointestinal cancers are generally firm, the presence and extent of a tumor can be assessed by touch during surgery. However, an objective scale for evaluating tissue hardness does not exist. We developed a new instrument, the endoscopic ultrasonic tactile sensor, that allows objective evaluation of hardness. In this study the usefulness of this device for diagnosis of the extent of gastric cancers was evaluated.Methods: Twenty-three patients with depressed or ulcerated early gastric cancers and 7 patients with active or healed gastric ulcers underwent endoscopic examination with the ultrasonic tactile sensor before gastrectomy.Results: Gastric cancers were significantly harder than normal mucosa or gastric ulcers. The histologic type of gastric cancer and the presence of ulceration did not affect tumor hardness and mucosal cancers could not be differentiated from submucosal or deeper cancers.Conclusions: This new ultrasonic tactile sensor was useful for endoscopic diagnosis of the extent of gastric cancers.
