Pure Laparoscopic Living Donor Left Lateral Sectionectomy in Pediatric Transplantation: A Propensity Score Analysis on 220 Consecutive Patients.

Left lateral sectionectomy for donor hepatectomy is a well-established alternative to deceased donor pediatric liver transplantation. However, very little is available on the laparoscopic approach (laparoscopic left lateral sectionectomy [L-LLS]). With the aim to assess safety, reproducibility under proctorship, and outcomes following living donor liver transplantation in children, a comparative single-center series using propensity score matching (PSM) to evaluate open left lateral sectionectomy (O-LLS) versus L-LLS was carried out in a relatively short time period in a high-volume pediatric transplant center. A retrospective, observational, single-center, PSM study was conducted on 220 consecutive living donor hepatectomies from January 2011 to April 2017. The variables considered for PSM were as follows: year of operation, recipient age, indication for transplant, recipient weight, donor sex, donor age, and donor body mass index. After matching, 72 O-LLSs were fit to be compared with 72 L-LLSs. Operative time and warm ischemia time were significantly longer in L-LLSs, whereas blood loss and overall donor complication rates were significantly lower. Postoperative day 1 and 4 pain scores were significantly less in the L-LLS group (P = 0.015 and 0.003, respectively). The length of hospital stay was significantly shorter in L-LLS (4.6 versus 4.1 days; P = 0.014). Overall donor biliary complications were 9 (12.5%) and 1 (1.4%) for O-LLS and L-LLS (P = 0.022), respectively. Vascular complications occurred in 3 (4.2%) children without graft loss in the laparoscopic group. The 1-, 3-, and 5-year overall patient survival rates were 98.5%, 90.9%, and 90.9% in the O-LLS group and in the L-LLS group 94.3%, 92.7%, and 86.8% (P = 0.28). In conclusion, L-LLS for donor hepatectomy is a safe and reproducible technique yielding better donor perioperative outcomes with respect to the conventional approach with similar recipient outcomes.

Feasibility of Full-Right/Full-Left Split-Liver Transplant in Pediatric Deceased Donors for Pediatric Recipients.

This case report describes the first ex situ full-right/full-left splitting of a liver from a pediatric deceased donor in the Middle East with an excellent outcome for both recipients. The left lateral split-liver transplant requires division of the deceased donor liver into a left lateral lobe for a pediatric recipient and an extended right lobe for an adult recipient, thus producing only 1 graft for a pediatric recipient. Full-right/full-left liver transplant, which splits the liver along the line of Cantlie, is a much more complex and challenging surgery, even though the technique is fully developed, and is theoretically able to produce 2 sizeable grafts for 2 pediatric recipients. However, the full-right/full-left liver transplant remains limited because of the small vascular structures and therefore was not recommended and was not previously described in the literature.

Safety and Feasibility Report of Robotic-assisted Left Lateral Sectionectomy for Pediatric Living Donor Liver Transplantation: A Comparative Analysis of Learning Curves and Mastery Achieved With the Laparoscopic Approach.

BACKGROUND: There is a growing interest in left lateral sectionectomy for donor hepatectomy. No data are available concerning the safety of the robotic (ROB) approach. METHODS: A retrospective comparative study was conducted on 75 consecutive minimally invasive donor hepatectomies. The first 25 ROB procedures performed from November 2018 to July 2019 were compared with our first (LAP1) and last 25 (LAP2) laparoscopic cases performed between May 2013 and October 2018. Short-term donors and recipients' outcomes were analyzed. RESULTS: No conversions were noticed in ROB whereas 2 conversions (8%) were recorded in LAP1 and none in LAP2. Blood loss was significantly less in ROB compared with LAP1 (P ≤ 0.001) but not in LAP2. Warm ischemia time was longer in ROB (P ≤ 0.001) with respect to the other groups. Operative time was similar in the 3 groups (P = 0.080); however, the hospital stay was shorter in ROB (P = 0.048). The trend in operative time in ROB was significantly shorter compared to LAP1 and LAP2: linear R2 0.478, P≤0.001; R2 0.012, P = 0.596; R3 0.004, P = 0.772, respectively. Donor morbidity was nihil in ROB, similar in LAP1 and LAP2 (n=3%-12%; P = 0.196). ROB procedures required less postoperative analgesia (P = 0.002). Recipient complications were similar for all groups (P = 0.274), and no early retransplantations were recorded. CONCLUSIONS: Robotic left lateral sectionectomy for donor hepatectomy is a safe procedure with results comparable to the laparoscopy in terms of donor morbidity and overall recipients' outcome when the procedure is performed by experts. Certainly, its use is currently very limited.

Clinical Practice Guidelines for Liver Transplantation in Saudi Arabia.

The demand for liver transplantation in the Kingdom of Saudi Arabia (KSA) is associated with the country's high burden of liver disease. Trends in the epidemiology of liver transplantation indications among recipients in KSA have changed over 20 years. Non-alcoholic steatohepatitis has eclipsed the hepatitis C virus in the country due to the effective treatment strategies for HCV. Risk factors for NASH, like type 2 diabetes mellitus, obesity, and hyperlipidemia, are becoming a major concern and a leading indication for liver transplantation in the KSA. There is also a significantly increased prevalence and incidence of genetic adult familial liver diseases in KSA. New immunosuppressive agents and preservation solutions, improved surgical capabilities, and early disease recognition and management have increased the success rate of liver transplant outcome but concerns about the side effects of immunosuppressive therapy can jeopardise long-term survival outcomes. Despite this, indications for liver transplantation continue to increase, resulting in ongoing challenges to maximize the number of potential donors and reduce patient mortality rate while expecting to get transplanted. The Saudi Center of Organ Transplant is the recognized National Organ Donation Agency for transplantation, which renders important support for procurement and allocation of organs. This guidance document aims to help healthcare providers in managing patients in the liver transplant setting.

Saudi association for the study of liver diseases and transplantation position statement on liver transplantation during the COVID-19 pandemic.

The World Health Organization (WHO), on March 11th 2020, upgraded the status of the novel coronavirus disease (COVID-19) from epidemic to pandemic. Over two million individuals have been infected with SARS-CoV-2, the virus causing COVID-19, and as of April, 14th 2020, there were over 5000 confirmed cases in Saudi Arabia (SA). Many countries, including SA, have imposed major restrictions on travel, and everyday life, and the implications of these necessary changes are being felt in liver transplant (LT) centers in SA. Concerns remain that there is an increased risk for individuals over 65 years of age, with underlying medical conditions, or for those who are immunocompromised. Therefore, the Saudi Association for the Study of Liver Diseases and Transplantation (SASLT) established an urgent task force to launch a statement that can be utilized by LT centers as a guidance in the management of patients with advanced liver disease from the time of LT listing to the post-operative care of transplanted patients.
