Application of high-resolution narrow band imaging and endocytoscopy for early diagnosis of esophageal neoplasia.

The worldwide incidence of esophageal carcinoma has been rising rapidly over the past few decades. However, in only 31% of patients the carcinoma is detected early in situ. It is essential to detect the malignancy early and to determine the extent of the disease to ensure the best option for a cure. Recent advances in endoscopic technology, including high-resolution magnification endoscopy, narrow-band imaging and endocytoscopy, have increased detection rates of oesophageal microcarcinomas. We report three cases of esophageal malignancy where the use of newer diagnostic techniques ensured an early diagnosis which led to a modified course of management.
