Background The aim of the present study was to clarify the anatomy between the left triangular ligament ( LTL ) and the appendix fibrosa hepatis ( AFH ) in order not to sever the AFH when dissecting the LTL . Methods Totals of 43 and 27 cadaveric livers were examined macroscopically and histologically, respectively. Results The LTL attached itself to the diaphragmatic surface of the AFH through almost all lengths of the AFH . This might be the reason why AFH is so often dissected together with the LTL . There were two types of relation between the LTL and the AFH ; in one type, the starting point of the LTL existed on the left liver and in the other type, it was on the AFH . Twenty‐five of 27 AFH included remnants of the bile duct and 12 of 25 AFH had comparatively large bile ducts, which was unexceptionally accompanied by the well‐developed peribiliary vascular plexus. AFH showed a variety of shapes, such as rectangular (6/43), long triangular (4/43), short triangular (7/43), triangular plus cordlike (11/43), cordlike (12/43) and bifurcated (3/43) types. Conclusions As AFH sometimes includes relatively large bile ducts, it is recommended for surgeons to sever the AFH not just simply by electrocautery but by ligating its stump securely.
