摘要
目的：探讨美蓝染色对胃良恶性病变的定牲及判定癌浸润深度的价值。方法：将０．３％美蓝用喷洒管经内镜直接在病变处喷洒染色。结果：５３例中Ⅰ型６例，Ⅱ ａ型６例，Ⅱ ａ＋Ⅱｃ型４例，Ⅱｃ型６例，Ⅲ型１９例，Ⅱｃ＋Ⅲ型１２例；粘膜内癌 ２４例，粘膜下癌 ２９例。染色后对癌浸润深度判断的准确率为粘膜内癌 ８２．５％，粘膜下癌 ８６．２％。结论：美蓝染色可使病变更加清晰，增加立体感，补充肉眼观察的不足，对鉴别病变的良恶性及判定癌浸润深度具有重要的价值。
Purpose: To evaluate the value of methylene blue staining to differentiate benign from ma- lignant lesions and estimate the depth of invasion. Methods: 0. 3 % methylene blue was sprinkled to the le- sions of 53 patients with early gastric carcinoma using spray tube under endoscopy. Results: Of 53 patients, 6 cases were Ⅰ type, 6 Ⅱ a type, 4 Ⅱ a+ Ⅱ c type, 6 Ⅱ c type, 19 Ⅲ type and 12 Ⅱ c+ Ⅲ type. 24 pa- tients with mucosal cancer and 29 submucosal cancer were determined by operation and endoscopic resec- tion. The correct rate of invasive depth of carcinoma determined by staining was 82. 5 % in mucosal cancer, 86. 2 % in submusocal cancer. Conclusions: Methylene blue staining can show distinctly the lesions, supple- ments insufficiency of observation with the naked eye. It has important value to differentiate benign from malignant lesions and estimate the invasive depth.
