Data are expressed as median (range) or mean ± SD, unless stated otherwise. In the paper from Belli, operation time, bleeding and postoperative hospital stay are described separately for patients whose previous hepatectomy was open (upper) or laparoscopic (lower). LLR: Laparoscopic liver resection; LR: Liver resection; HCC: Hepatocellular carcinoma; LLS: Left lateral sectorectomy; Met: Metastasis; Minor: Resection of 2 segments or less; Major: Resection of 3 segments or more; ND: Not documented; Pt: Partial resection; Sec: Sectionectomy; Seg: Segmentectomy; Subseg: Subsegmentectomy; IQR: Interquartile range; NC: Not countable.
