Core Tip
Core tip: A novel chromoendoscopy procedure using an acetic acid indigocarmine mixture (AIM) is effective for recognizing the margins of early gastric cancer (EGC). In some cases the color of the EGC area gradually becomes reddish after instillation of the AIM solution. The study shows that the sensitivity of AIM-chromoendoscopy (AIM-CE) in the diagnosis of EGC was significantly higher than that of white light endoscopy, but the specificity and accuracy were not. AIM-CE may have potential for screening EGC in patients initially diagnosed as gastric adenoma by forceps biopsy.
