On page 250, the authors would like to add the following sentences and reference numbers 14 and 15 to the section
“Combined resection of the caudate lobe”:
In 1986, in an English-language journal, Mizumoto et al. of Mie University reported the surgical treatment of 32 patients
with perihilar cholangiocarcinoma. Of these patients, 26 underwent operation; 12 had invasion of the liver at the hilum
and 11 had invasion of the caudate lobe. They investigated the anatomy of the hilar area, including vascular structures
of the caudate lobe in 106 cadavers in details. Based on these ﬁndings, the necessity of the combined resection of the
caudate lobe was proposed . Thereafter, this procedure has been widely performed for perihilar cholangiocarcinoma,
leading to the improvement of surgical outcomes of this disease .
