Abstract

Objective: Evaluating the correlation of invasion depth and DOI vascular characteristics in early esophageal cancer. Materials and method: This was a Cross-sectional descriptive study on 82 patients with lesions suspected of early esophageal cancer (UTTQS), who underwent diagnostic endoscopy and evaluated the depth of invasion (DOI). Endoscopic submucosal dissection at K hospital. After intervention, patients were evaluated for the correlation between the depth of invasion on histopathology and the depth of invasion through endoscopy before intervention. Results: The mean age of the patients was 58.22 ± 6.58, the mean lesion size was 29.30 ± 15.02  mm. The most common macroscopic are flat type 0IIb (43.8%) and slightly superficially depressed type 0IIc (39%). Lesions of squamous cell carcinoma in situ accounted for mainly 58.5%, esophageal carcinoma invade mucosae was less common (26.8%). The percentage of cases with a negative cross section reaches 93.9%. Conclusions: 82 patients had endoscopic features consistent with the results of early esophageal cancer and There is a correlation between the depth of invasion after intervention and the depth of invasion before intervention assessed through narrow-band endoscopy with magnification.
