Preoperative and intraoperative gastric tumor localization

ABSTRACT

As the incidence of early gastric cancer increases, gastric tumor localization has become an important issue. Several diagnostic methods have been proposed for preoperative and intraoperative gastric tumor localization. These include endoscopic metal clipping, computed tomographic gastrography, endoscopic tattooing, and intraoperative endoscopy. However, in spite of various methods, tumor localization has its limitations; thus, new diagnostic alternatives need to be developed.
