| [ Summary ] | Precise resection was impossible with EMR because a snare was used to resect lesions. However, large, precise resection may be performed with ESD. Therefore, when the cut margin was positive after ESD, the reason may be misdiagnosis of lateral extension. Diagnosis of lateral extensions of superficial gastric cancer was sometimes difficult with conventional endoscopy. However, vascular and pit patterns observed by magnified endoscopy could help achieve precise diagnosis. Acetic acid and Narrow Band Imaging (NBI) provide additional information. When the diagnosis of lateral extensions is difficult with conventional endoscopy, precise diagnosis may be possible by employing magnified endoscopy with acetic acid and NBI system. |
