 We studied the indications for endoscopic mucosal resection(EMR), which has a size limitation, and endoscopic submucosal dissection(ESD)for lump resection of esophageal squamous cell carcinoma(SCC)based on investigation of the results in cases that underwent EMR in our hospital. The study population consisted of 106 patients treated by EMR with lump resection for lesions <25 mm in diameter between January 2005 and December 2006. The depths of invasion in these 106 cases were as follows : T1a-EP(n=76),T1a-LPM(10),T1a-MM(14),SM1(2), and SM2(4). The lesion size distribution was as follows : minute carcinoma≦5 mm(n=13), small carcinoma 5 mm to 10 mm(25),10 mm to 15 mm(36),15 mm to 20 mm(21),>20 mm(11). The ratio of lump resection in each size class were as follows : minute carcinoma≦5 mm,100% ; small carcinoma 5 mm to 10 mm,100% ; 10 mm to 15 mm,97% ; 15 mm to 20 mm,83% ; and >20 mm in diameter,78%.

 In endoscopic resection of early squamous cell carcinoma of the esophagus, complete eradication by one-piece resection and precise histological examinations on resected specimen allow us to avoid local recurrence and to provide appropriate adjuvant treatment. In cases with lesions less than 15mm in size,EMR is recommended for frequent one-piece resection and easier manipulation compared to ESD. Although ESD requires difficult manipulation, it should be indicated for lesions over 15mm in size, for it provides frequent one-piece resection than EMR.
