Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. Evolution of laparoscopic techniques helps to a great extent in facilitating and replacing the conventional surgical maneuvers. This article describes the novel use of narrow band imaging (NBI) in laparoscopic radiofrequency ablation (LRFA) of exophytic HCC to ensure its adequate ablation. In total, 11 patients with proven HCC were recruited to perform LRFA; NBI were applied during and after completion of ablation session, with NBI, the exophytic HCC appears dark green or blue in color and after start of LRFA; the tumor capsule turned into red color denoting hemoglobin coagulation and vascular damage; in 5 cases and after completion of ablation; the tumor capsule was still dark green or blue denting viability which necessitates needle repositioning and ablation continuation. NBI helps to a great extent in confirmation of successful ablation of exophytic HCC.
肝细胞癌（HCC）是全球癌症死亡的第二大主要原因。腹腔镜技术的发展在很大程度上有助于促进和取代传统的外科手术操作。本文描述了窄带成像（NBI）在腹腔镜下对肝外生型HCC进行射频消融（LRFA）中的新应用，以确保充分消融。总共招募了11例经证实的HCC患者进行LRFA；在消融过程中和完成后应用NBI，在NBI下，肝外生型HCC在消融开始后呈深绿色或蓝色；肿瘤包膜变为红色，表示血红蛋白凝固和血管损伤；在5例患者中，消融完成后，肿瘤包膜仍为深绿色或蓝色，表明仍有活力，这需要重新定位针并继续消融。NBI在很大程度上有助于确认肝外生型HCC的成功消融。
