Comparing indications, complexity and outcomes of laparoscopic liver resection between centers with and without a liver transplant program: a French nationwide study.

BACKGROUND: There are no data to evaluate the difference in populations and impact of centers with liver transplant programs in performing laparoscopic liver resection (LLR).

METHODS: This was a multicenter study including patients undergoing LLR for benign and malignant tumors at 27 French centers from 1996 to 2018. The main outcomes were postoperative severe morbidity and mortality.

RESULTS: A total of 3154 patients were included, and 14 centers were classified as transplant centers (N = 2167 patients, 68.7 %). The transplant centers performed more difficult LLRs and more resections for hepatocellular carcinoma (HCC) in patients who more frequently had cirrhosis. A higher rate of performing the Pringle maneuver, a lower rate of blood loss and a higher rate of open conversion (all p < 0.05) were observed in the transplant centers. There was no association between the presence of a liver transplant program and either postoperative severe morbidity (<10 % in each group; p = 0.228) or mortality (1 % in each group; p = 0.915).

CONCLUSIONS: Most HCCs, difficult LLRs, and cirrhotic patients are treated in transplant centers. We show that all centers can achieve comparable safety and quality of care in LLR independent of the presence of a liver transplant program.
