Endoscopic resection (ER) has gained more and more importance in the treatment of early gastrointestinal neoplasia over the last few years. The choice of the different available techniques depends on the site, the macroscopic type of the tumour and the personal experience of the endoscopist. The 'suck-and-cut' technique with ligation device or cap should be favoured to normal strip biopsy in the oesophagus because of the size of the resected specimen and its technical feasibility. A recently described method of ER in the stomach is the circumferential mucosal incision with a type of needle-knife and subsequent en-bloc resection following prior injection under the lesions. ER of high-grade intraepithelial neoplasia and mucosal adenocarcinoma in Barrett's oesophagus should be considered as the treatment of choice. First mid-term results of endoscopic therapy of early squamous-cell neoplasia in the oesophagus show promising results; however, long-term results are awaited. Studies with large numbers of patients in Japan proved the efficiency and safety of ER in low-risk early gastric carcinoma. Duodenal lesions and adenomas of the major duodenal papilla were also proved to be treated successfully by ER. In the colon, ER is used successfully for resection of adenomas and small well-differentiated or moderately differentiated carcinomas that are restricted to the mucosa. ER of gastrointestinal lesions is a safe and effective method but should be performed only by experienced endoscopists.
