Background and purpose:Endoscopic treatment is a promising therapeutic option for superifcial lesions throughout the gastrointestinal tract, this study was aimed to evaluate the efficacy of endoscopic resection (ER) using the new Duette multiband mucosectomy kit (DT-6) on treating esophageal disease. Methods:Since Jun. 2011, ER using DT-6 has been performed on 100 patients in a tertiary medical center. Data from those who have been followed up for over 6 months was analyzed. ER and esophagectomy were compared on treating high grade dysplasia (HGD) lesions and early esophageal cancer. Results:From Jun. 2011 to Jan. 2012, a total of 32 patients with esophageal lesions underwent 34 ER using DT-6 (22 male and 10 female, mean age 59.0 years, range 25 to 83 years). There were (3.4±1.0) specimen resected per operation, and the average greatest diameter was (11.8±2.7)mm. Intraoperative blood loss was (5.45±1.47)mL. The median follow-up period was 8.2 months with a 100%half-year-follow-up rate. Except one pneumothorax occurred during one endoscopic submucosal dissection (ESD), no other complications happened. When Comparing ER and esophagectomy on treating HGD and early esophageal cancer, ER showed advantages in terms of operation time, intraoperative blood loss, hospital stay and complications. Conclusion:ER using DT-6 is safe, simple, minimally invasive and effective for esophageal disease. Prospective study and long follow-up are needed to compare endoscopic resection and esophagectomy for HGD and early esophagus cancer.
