BACKGROUND: Although isolated caudate lobe (CL) liver resection is not a contraindication for minimally invasive liver surgery (MILS), feasibility and safety of the procedure are still poorly investigated. To address this gap, we evaluate data on the Italian prospective maintained database on laparoscopic liver surgery (IgoMILS) and compare outcomes between MILS and open group.METHODS: Perioperative data of patients with malignancies, as colorectal liver metastases (CRLM), hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), non-colorectal liver metastases (NCRLM) and benign liver disease, were retrospectively analyzed. A propensity score matching (PSM) analysis was performed to balance the potential selection bias for MILS and open group.RESULTS: A total of 224 patients were included in the study, 47 and 177 patients underwent MILS and open isolated CL resection, respectively. Theoverall complication rate was comparable between the two groups; however, severe complication rate (Dindo-Clavien grade≥3) was lower in the MILS group (0% versus 6.8%, P=ns). In-hospital mortality was 0% in both groups and mean hospital stay was significantly shorter in the MILS group (P=0.01). After selection of 42 MILS and 43 open CL resections by PSM analysis, intraoperative and postoperative outcomes remained similar except for the hospital stay which was not significantly shorter in MILS group.CONCLUSIONS: This multi-institutional cohort study shows that MILS CL resection is feasible and safe. The surgical procedure can be technically demanding compared to open resection, whereas good perioperative outcomes can be achieved in highly selected patients. (The IgoMILS – Sg1 Group)

Abstract
BACKGROUND: Although isolated caudate lobe (CL) liver resection is not a contraindication for minimally invasive liver surgery (MILS), feasibility and safety of the procedure are still poorly investigated. To address this gap, we evaluate data on the Italian prospective maintained database on laparoscopic liver surgery (IgoMILS) and compare outcomes between MILS and open group.METHODS: Perioperative data of patients with malignancies, as colorectal liver metastases (CRLM), hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), non-colorectal liver metastases (NCRLM) and benign liver disease, were retrospectively analyzed. A propensity score matching (PSM) analysis was performed to balance the potential selection bias for MILS and open group.RESULTS: A total of 224 patients were included in the study, 47 and 177 patients underwent MILS and open isolated CL resection, respectively. Theoverall complication rate was comparable between the two groups; however, severe complication rate (Dindo-Clavien grade≥3) was lower in the MILS group (0% versus 6.8%, P=ns). In-hospital mortality was 0% in both groups and mean hospital stay was significantly shorter in the MILS group (P=0.01). After selection of 42 MILS and 43 open CL resections by PSM analysis, intraoperative and postoperative outcomes remained similar except for the hospital stay which was not significantly shorter in MILS group.CONCLUSIONS: This multi-institutional cohort study shows that MILS CL resection is feasible and safe.
