AIM: @entity5436 ( @entity5436 ) precedes the development of @entity957 . Detection of the lesion is essential to management. This paper describes a prospective study to detect and ablate anal @entity2784 ( @entity2784 ) using white light (WL) narrow band imaging (NBI) and NBI with @entity1543 (NBIA). METHOD: Sixty @entity1 with abnormal anal cytology and risk factors for @entity24103 , underwent examination of the anoderm with a high definition gastroscope and NBIA. Targeted biopsies were taken and the lesions ablated and characterized histopathologically. Visualisation of the anal transitional zone (ATZ) was facilitated by retroflexion and examination through a disposable anoscope. RESULTS: Targeted biopsies were taken from lesions in 58 @entity1 . No lesion was seen in two @entity1 . Histopathology showed @entity2784 in 48 (80.0%) of 60 biopsies. One biopsy showed @entity706 . Biopsies in 9 (15%) of the 60 @entity1 showed normal mucosa. Lesions were seen in white light in 27 (45%) of the 60 cases, NBI in 39(65%) and NBIA in 57(95%) . There was no major morbidity. Sensitivity analysis showed that all methods were significantly different from each other. CONCLUSION: Anal @entity2784 in the ATZ and anal canal can be identified by NBIAPatient selection influences findings. Limitations include small sample size and non-randomization.
