Few resources exist for surgical learners in interpreting trends in biochemical markers following major hepatic resections. Adult patients who underwent major hepatectomy between 2010 and 2020 were included from twelve international centers. Patients were classified as healthy donor, benign disease, non-alcoholic fatty liver disease, prior chemothe...

Although meta-analyses and systematic reviews have clarified the benefits of robotic surgery, few studies have focused on robotic rectal surgery (RRS) and the use of Endowrist® instruments. Therefore, we evaluated RRS using the double bipolar method (DBM) and compared its short-term outcomes with those of RRS using the single bipolar method (SBM)....

Less morbidity is considered among the advantages of laparoscopic liver resection (LLR) for HCC patients. However, our previous international, multi-institutional, propensity score-based study of emerging laparoscopic repeat liver resection (LRLR) failed to prove this advantage. We hypothesize that these results may be since the study included comp...
