Reviewer's report:
This paper is a well-written article reporting a rare case of situs inversus totalis
(SIT) with jumping metastasis of gallbladder carcinoma.
SIT is congenital anatomic abnormality rarely experienced by gastrointestinal
surgeons. In many cases, standardized techniques for normal anatomy are not
applicable, and the degree of abnormality varies, making it necessary to consider
the appropriate technique for each case. In addition, this case showed jumping
metastasis, suggesting the need for further analysis of the metastatic route in SIT
cases with gastrointestinal cancer. From this perspective, this case report is very
meaningful for gastroenterological surgeons.
However, there are only one point to be commented.
