Accuracy and efficacy of narrow-band imaging versus white light hysteroscopy for the diagnosis of endometrial cancer and hyperplasia

NBI showed significantly higher values in sensitivity for the detection of low-risk and high-risk hyperplasia, and this could be useful for reducing the risk of missing severe pathologies at hysteroscopy, and improving the diagnosis of preneoplastic and neoplastic pathologies. NBI hysteroscopy showed a very high diagnostic accuracy for the exploration of the uterine cavity, reducing the number of biopsies performed in wrong areas, although multicenter randomized trials are required to establish the true value of this interesting technological advancement.
