BACKGROUND: This study aimed to determine the risk factors for severe postoperative complications in patients undergoing pure laparoscopic liver resection (LLR) for tumors in the right posterosuperior (PS) segments.
METHODS: The study included 289 patients who underwent parenchyma-sparing pure LLR for tumors in the right PS segments at eight treatment centers between January 2009 and December 2019.
RESULTS: Multivariate analysis revealed tumor size ≥3 cm (P = .016), segmentectomy (P = .044), and liver cirrhosis (P = .029) as independent risk factors for severe postoperative complications. The severe complication rates (2.7% vs 12.1%, P = .0025), median intraoperative blood loss (100 mL vs 150 mL, P = .001), and median operation time (248 minutes vs 299.5 minutes, P = .0013) were lower in the patients without all these three risk factors than those with at least one risk factor. The median length of postoperative hospital stay was shorter in patients with no risk factors than those with at least one risk factor (9 days vs. 10 days, P = .001).
CONCLUSIONS: Tumor size ≥3 cm, segmentectomy, and liver cirrhosis were the risk factors for severe postoperative complications after parenchyma-sparing pure LLR for tumors in the right PS segments. Patients without these three risk factors would be appropriate candidates for safely performing parenchyma-sparing pure LLR in the right PS segments at the outset.
