Abstract
Background
Data regarding laparoscopic liver resections(LLRs) for Gallbladder cancer(GBC) and
Intrahepatic Cholangiocarcinoma(iCCA) are sparse. This study compared LLRs with open
liver resections(OLRs) in a high-volume center.
Methods
Data of patients who underwent LLR or OLR for GBC or iCCA at Mayo-Clinic between 01/2016
and 04/2021 were retrospectively compared. Proportional hazards models were used to
compare the approach on survival.
Results
32 and 52 patients underwent LLR and OLR during the study period, respectively. 64
and 20 patients had iCCA and GBC, respectively. LLR had lower median blood loss (250 mL
vs. 475 mL, p = 0.001) and shorter median length of stay compared to OLR (3.0 days
vs. 6.0 days, p = 0.001). LLR and OLR did not differ in post-operative major complication
(25% vs. 32.7%, p = 0.62), negative margin (100% vs. 90.4%, p = 0.15) and completeness
of lymphadenectomy rates (36.8% vs. 45.5%, p = 0.59). The median number of harvested
lymph node was 4.0 and 5.0 for LLR and OLR, respectively (p = 0.347). There were no
associations between approach and 3-year overall and disease-free survival between
LLR and OLR (49.8% vs. 63.2% and 39.6% vs. 21.5%, p = 0.66 and p = 0.69).
Discussion
With appropriate patient selection and when compared to OLRs, LLRs for GBC and iCCA
are feasible, safe and offer potential short-term benefits without compromising on
oncological resection principals and long-term outcomes.
