METHODS： A total of 112 patients with over 10 mm EGC were treated with IT-ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 5 year period from January 2002 to December 2006, including 40 patients with over 20 mm EGC. We compared patient backgrounds, the one-piece resection rate, complete resection （CR） rate, operation time, bleeding rate, perforation rate between patients with over 20 mm EGC [over 20 mm group （21-40 ram）] and the remaining patients （under 20 mm group）. RESULTS： We found no significant difference in the rate of underlying cardiopulmonary disease （over 20 mm group vs under 20 mm group, 5.0% vs 5.6%）, one- piece resection rate （95% vs 96%）, CR rate （85% vs 89%）, operation time （72.3 rain vs 66.5 rain）, bleeding rate （50 vs 4.2%）, and perforation rate （0% vs 1.4%） between the 2 groups. Three patients in each group had submucosal invasion and two in each groups underwent additional surgery. CONCLUSION： There was no significant difference in the outcome resulting from IT-ESD between the 2 groups. Our study proves that IT-ESD is a feasible treatment for patients with over 20 mm mucosal gastric cancer although the long-term outcome should be evaluated in the future.展开更多

However, there are many uncertain areas such as indications of EIR, best treatment methods, management of complications and follow-up methods after the procedure. Host studies on this topic have been carried out by researchers in Japan. In Korea, gastric cancer is the most common malignant disease, and the second leading cause of cancer death. In these days, EIR for EGC is widely performed in many centers in Korea. In this review, we will provide an overview of the bechniques and outcomes of EIR in Korea.展开更多

A case of esophagotracheal fistula secondary to esophagitis 9 years after esophagectomy and gastric pull-up for treatment of esophageal carcinoma is described. It was successfully treated with transposition of a pedicled pectoralis major muscle flap.展开更多
