Minimally invasive approaches are increasingly being applied in surgeries and have recently been used in living donor hepatectomy. We have developed a safe and reproducible method for minimally invasive living donor liver transplantation, which consists of pure laparoscopic explant hepatectomy and pure laparoscopic implantation of the graft, which was inserted through a suprapubic incision. Pure laparoscopic explant hepatectomy without liver fragmentation was performed in a 60-year-old man with alcoholic liver cirrhosis and hepatocellular carcinoma. The explanted liver was retrieved through a suprapubic incision. A modified right liver graft, procured from his 24-year-old son using the pure laparoscopic method, was inserted through a suprapubic incision, and implantation was performed intracorporeally throughout the procedure. The time required to remove the liver was 369 min, and the total operative time was 960 min. No complications occurred during or after the surgery. The patient recovered well, and his hospital stay was of 11 days. Pure laparoscopic living donor liver transplantation from explant hepatectomy to implantation was performed successfully. It is a feasible procedure when performed by a highly experienced surgeon and transplantation team. Further studies with larger sample sizes are needed to confirm its safety and feasibility.
Minimally invasive surgery has been introduced for liver transplantations. Although laparoscopic or robot‐assisted living donor hepatectomy is being used, minimally invasive surgery is rarely performed in recipients during liver transplantation. A 63‐year‐old patient (body mass index: 21.9 kg/m2) with primary biliary cirrhosis underwent total laparoscopic explant hepatectomy, followed by robot‐assisted liver engraftment using advanced technological innovations. The total operation time for the recipient was 12 h 20 min, including laparoscopic explant hepatectomy (140 min) and robot‐assisted engraftment (220 min). Achieving hepatic and portal vein anastomoses consumed 35 and 28 min, respectively. The hepatic artery anastomosis and bile duct reconstruction took 83 and 66 min, respectively. The estimated blood loss was 3600 ml. The warm and cold ischemic times were 87 and 220 min, respectively. The patient received 10 units each of red blood cells and fresh frozen plasma during the surgery and recovered from early allograft dysfunction after liver transplantation. This case study suggests that laparoscopic explant hepatectomy followed by robot‐assisted engraftment is feasible in selected recipients only. We obtained informed consent for this innovative procedure from the patient and from her living donor.
Purpose
The aim of this study was to compare surgical outcomes after liver resection for hepatocellular carcinoma (HCC) according to tumor size using a large, nationwide cancer registry-based cohort and propensity score matching.
Methods
From 2008 to 2015, a total of 12,139 patients were diagnosed with liver cancer and registered in the Korean Primary Liver Cancer Registry. Patients without distant metastasis who underwent hepatectomy as a primary treatment were selected. We performed 1:1 propensity score matching between the small (<5 cm), large (≥5 cm and <10 cm), and huge (≥10 cm) groups.
Results
Overall, 265 patients in the small and large groups were compared, and 64 patients each in the large and huge groups were compared. The overall and progression-free survival rates were significantly lower in the large group than in the small group (P < 0.001 and P < 0.001, respectively). Overall survival tended to be poorer in the huge group than in the large group (P = 0.051). The progression-free survival rate was significantly lower in the huge group than in the large group (P = 0.002).
Conclusion
Although primary liver resection can be considered even in patients with huge HCC, greater caution with careful screening for recurrence is needed.
