Background: Sequential liver-kidney transplantation (SeqLKT) from the same living donor has shown excellent results in children with primary hyperoxaluria type 1 (PH1), yet its experience is limited due to the invasiveness of two major procedures for liver-kidney procurement in a single donor. Despite laparoscopic nephrectomy and hepatic left lateral sectionectomy (LLS) being considered standard procedures in living donation, the sequential use of the two laparoscopic approaches in the same living donor has never been reported. Methods: Herein, we present the first two case series of laparoscopic liver-kidney procurement in the same living donor for SeqLKT in children with PH1 and review of the current literature on this topic. Results: In the first case, a 15-month-old boy received a SeqLKT from his 32-year-old mother, who underwent a laparoscopic LLS and, after 8 months, a laparoscopic left nephrectomy. In the second case, a 34-month-old boy received a SeqLKT from his 40-year-old father who underwent laparoscopic LLS followed by hand-assisted right nephrectomy after 4 months. Both donors had uneventful postoperative courses and were discharged within 5 days from each surgery. The first recipient had no complication; the second child after liver transplantation developed a partial thrombosis of the inferior vena cava, which did not preclude the sequential kidney transplantation. After 12 months, donors and recipients displayed normal liver and renal functions. Conclusions: Sequential laparoscopic liver-kidney procurement in the same living donor is safe and feasible, and might be considered as a possible strategy to promote SeqLKT in children with PH1 from the same living donor.
