【摘要】 目的 提高内镜下粘膜切除术对消化道早期癌的完全切除率。方法 采用复方碘溶液、煌蓝、美蓝对食管、胃、直肠早期癌灶染色，然后行内镜下外套管粘膜切除术。结果 从1994年至1998年共治疗12例早期癌病例。平均病灶直径(15.7±9.8)mm(3～30mm)。术后1、3、6、12、24及36个月复查胃镜或肠镜并活检。其中2例癌细胞残留，1例为食管癌，另1例为直肠癌。这2例原发病灶均大于25mm，辅以放射治疗或外科手术。内镜下完全切除率为83.3%，其中8例随访期>36个月，存活率为87.5%。结论 染色技术加内镜下外套管粘膜切除术可提高消化道早期癌的完全切除率。

【Abstract】 Objective The modified methodswere used simply to raised the likelihood of complete mucosectomy for early cancer ofdigestive tract.Methods Lugol’s solution , brilliant and methyleneblue were taken as dyes to stain mucosal lesions for better visualization ; endoscope without-pipe was applied to facilitate procedures.Results 12 patients withearly cancer were treated in past 5 years. The lesions treated ranged 3～30 ( mean 15.7±9.8)mm in diameter. All were rechecked by endoscopy and pathology at 1, 3, 6, 12, 24 and 36months postoperatively.Most (83.3%) had complete removal,8 being followed up for more than3 years, with a survival rate of 87.5%. Residual cancer cells were found in 2 caseswith lesions as large as 25 mm followed by surgery and radiation.Conclusion The percentage of complete mucosectomy for early cancer could be increased with thismodification.
