Abstract Background Hepatocellular carcinoma (HCC) is prevalent in Taiwan, primarily due to the high incidence of hepatitis B and C infections, with high recurrence rates of 50–70% within five years after initial treatment. Treatment options for recurrent HCC include salvage liver transplantation, trans-arterial chemoembolization, re-hepatectomy, and radiofrequency ablation. Repeat hepatectomy exhibits superior oncological outcomes compared with alternative approaches. Although laparoscopic liver resection has demonstrated safety and feasibility for primary HCC resection, the persistence of intrahepatic recurrence necessitates effective intervention. However, repeat liver resection poses several challenges including adhesions from previous surgeries, limited access to recurrent tumors, altered liver structure post-regeneration, difficulties in obtaining hilar control, and compromised liver reserves. Suggesting a laparoscopic approach for recurrent HCC is typically based on the surgeons’ experience and confidence. In this study, we reconfirmed the safety, feasibility and oncological outcome of laparoscopic repeat liver resection and investigated the optimal timing for initiation of this procedure by a pioneering team in minimally invasive liver resection. Methods We retrospectively reviewed our collective experience of 57 patients with recurrent HCC between January 2009 and December 2021.The patients were followed until June 30, 2024. Among them, 37 underwent laparoscopic approaches and 20 opted for open procedures. Results Both groups exhibited similar operative times and perioperative outcomes, with significantly reduced hospital stays in the laparoscopic cohort (median: 5 vs. 7, p |
