[Recent endoscopic treatment in gastroenterology]

Endoscopic diagnosis and treatment became to be necessary in gastroenterology for last two decades. Indication of endoscopic treatment is amazingly expanding because of developing new techniques and easy-to-use devices. Nowadays, the indication for endoscopic treatment includes the removal of foreign bodies in alimentary tract, the dilatation of stricture lesions by balloon or expandable metallic stent, the resection of polypoid and superficial tumors by polypectomy and EMR (endoscopic mucosal resection) techniques, the injection sclerotherapy and ligation method for gastroesophageal varices, the hemostasis of gastrointestinal hemorrhages by injection method or heat-burn method. In biliary and pancreatic area, there are some endoscopic treatments that are removal and destruction of stones in common bile duct, biliary and pancreatic drainage by tubing method. Our results of endoscopic resection for esophageal and gastric tumors are shown in this papers. In conclusion, complete resection that means histologically tumor negative of lateral and vertical margin of resected specimen is important to prevent recurrence of tumors after resection.
