Chinese expert consensus on the theoretical and technical system of laparoscopic portal terri-tory staining guided anatomic liver resection (2023 edition)

The effect of traditional anatomic liver resection for hepatocellular carcinoma is insufficient due to the limitation of technical conditions. Laparoscopic portal territory staining guided anatomic liver resection based on modern three-dimensional reconstruction and portal territory analysis as well as indocyanine green fluorescence navigation system, can achieve higher quality complete resection of tumour‑bearing portal territory to obtain surgical oncology and perioperative effects for hepatocellular carcinoma. Editorial Board of Chinese Journal of Digestive Surgery and Society for Hepato‑pancreato‑biliary Surgery of Chinese Research Hospital Association organize experts in the related field in China to carry out in‑depth discussions and repeated arguments, formu-lating Chinese expert consensus on the theoretical and technical system of laparoscopic portal territory staining guided anatomic liver resection (2023 edition). The purpose of this consensus is to improve and standardize the theoretical and technical system of laparoscopic portal territory staining guided anatomic liver resection, and to lay a foundation for further exploration of scientific questions in this field and the promotion with safety and standard.
