Abstract:Objective To investigate the utility of endoscopic characteristic and diagnostic method in early gastric cancer (EGC). Methods The chromoendoscopy and magnifying endoscopy were retrospectively analyzed in 73 patients of EGC, endoscopic biopsy of the abnormal expression mucosa was done according to the surface pattern and microvascular pattern, the cancer was resected by ESD or surgical, the pathological diagnosis of the postoperative as the final diagnosis. To record and analyzed the results of the whole process. Results 86 lesions in 73 patients were examined with white light endoscopy, which included 9 patients with 2 lesions and 2 patient with 3 lesions, the type of 0-IIc was 43.84% .The pit patterns of 23 lesions were type Ⅲ, 44 lesions were type Ⅳand 19 lesions were type Ⅴ. The microvascular pattern of 51 lesions were regular (59.30%), 29 lesions were irregular (33.72%) and microvessel structure of 6 lesions wasn't found (6.98%). The coincidence rate in white light endoscopy and pathological diagnosis was 60.46% (52/86), basic coincidence rate was 72.09% (62/86). The complete coincidence rate in magnifying endoscopy and pathological diagnosis was 93.02% (80/86) and the basic rate was 96.51% (83/86), there were significant differences between in the diagnostic accuracy between the two groups methods, P < 0.05. Conclusion The medical imaging characteristics of EGC by endoscopy may be found, we can to improve the recognition ability and the level of diagnosis of EGC.
