Although the well‐accepted lower limit of the graft‐to‐recipient weight ratio (GRWR) for successful living donor liver transplantation (LDLT) remains 0.80%, many believe grafts with lower GRWR may suffice with portal inflow modulation (PIM), resulting in equally good recipient outcomes. This study was done to evaluate the outcomes of LDLT with small‐for‐size grafts (GRWR <0.80%). Of 1321 consecutive adult LDLTs from January 2012 to December 2017, 287 (21.7%) had GRWR <0.80%. PIM was performed (hemiportocaval shunt [HPCS], n = 109; splenic artery ligation [SAL], n = 14) in 42.9% patients. No PIM was done if portal pressure (PP) in the dissection phase was <16 mm Hg. Mean age of the cohort was 49.3 ± 9.1 years. Median Model for End‐Stage Liver Disease score was 14, and the lowest GRWR was 0.54%. A total of 72 recipients had a GRWR <0.70%, of whom 58 underwent HPCS (1 of whom underwent HPCS + SAL) and 14 underwent no PIM, whereas 215 had GRWR between 0.70% and 0.79%, of whom 51 and 14 underwent HPCS and SAL, respectively. During the same period, 1034 had GRWR ≥0.80% and did not undergo PIM. Small‐for‐size syndrome developed in 2.8% patients. Three patients needed shunt closure at 1 and 4 weeks and 60 months. The 1‐year patient survival rates were comparable. In conclusion, with PIM protocol that optimizes postperfusion PP, low‐GRWR grafts can be used for appropriately selected LDLT recipients with acceptable outcomes.
Advances in medical and surgical techniques associated with multidisciplinary teams including skilled pediatric liver transplant surgeons, anesthetists, dedicated pediatric hepatologists, pediatric intensivists, interventional radiologists and pathologists resulted in an excellent outcome of living related liver transplants in children. Low age and weight of the baby does not seem to be a contraindication for liver transplantation as outcome were comparable in our experience.
SummaryMagnesium sulphate is used extensively in the treatment of eclampsia, and is also used to treat refractory arrhythmias, asthma, myocardial ischaemia and acute respiratory failure. We studied the interaction between magnesium sulphate and the anaesthetic agents propofol, rocuronium bromide and fentanyl citrate. This randomised, double blind study was conducted in 50 patients. The magnesium group A (n = 25) received 30 mg.kg )1 magnesium sulphate before induction of anaesthesia and 10 mg.kg )1 continuously intra-operatively until the end of surgery. Group B (n = 25) received the same volume of isotonic saline. Propofol, rocuronium and fentanyl infusions were started and the patients lungs' were ventilated with 33% oxygen in nitrous oxide. Anaesthetic depth was maintained at a bispectral index value of between 40 and 60. Muscle relaxation was maintained at a train-of-four count of 1 throughout surgery using neuromuscular monitoring. The fentanyl infusion was titrated to haemodynamic variables: heart rate and blood pressure. We concluded that magnesium sulphate has anaesthetic, analgesic and muscle relaxation effects and significantly reduces the drug requirements of propofol, rocuronium and fentanyl during anaesthesia.
MSUD occurs due to deficiency of enzyme BCKAD required for metabolism of leucine, isoleucine, and valine leading to the accumulation of these and their ketoacids causing acute metabolic decompensation manifesting as encephalopathy or sudden death. The patient requires special protein-restricted diet to survive. As this enzyme is expressed in liver, liver transplantation has been successfully performed as a cure. We report two patients of MSUD who underwent LDLT while their livers were used as a domino graft for other biliary cirrhotic patients. A 22-month-old male child diagnosed as a case of classic MSUD underwent LDLT from an altruistic aunt as donor following which his serum leucine levels normalized on an unrestricted protein diet. His liver was used as a domino graft. A 38-month-old female child with diagnosed MSUD underwent LDLT from a swap donor, and her liver was used as a domino graft. Her DQ improved post-transplant. LDLT from non-heterozygous donors is a cure for classical MSUD. Their livers can be used as domino grafts for non-MSUD cases.
Background: Coronavirus disease 2019 (COVID-19) pandemic has led to deferral of elective transplants and proactive pretransplant testing of the donor/recipient. The impact of these on living-donor liver transplantation (LDLT) activity and outcome is not known. We performed LDLT only for sick patients or patients with advanced hepatocellular carcinoma in this period, with special COVID protocols. Methods: Patients undergoing LDLT counseling, evaluation, and transplant in the period March to June 2020 (group A) under COVID-19 restrictions and special protocols were included. LDLT activity and outcomes among these patients were compared with those in the same period in 2019 (group B). Results: In the period March 15-June 10, we performed 39 and 23 (59%) LDLTs in 2019 and 2020, respectively. The adult patients with cirrhosis in group A (n = 20) had a significantly higher MELD score, 19.8 ± 7.0 versus 16.1 ± 5.6 in group B (n = 36), p = 0.034. Early recipient mortality was similar in 2019 (2/39) and 2020 (2/23). One of 23 post-transplant recipients, 3/71 recipients and donors during evaluation, and 8/125 healthcare workers (HCWs) developed COVID-19, all of whom recovered uneventfully. Conclusion: LDLT activity substantially reduced during the COVID era. The incidence and outcome of COVID-19 among the waiting or transplanted patients and HCWs were similar to those of the general population. The outcome after LDLT in the COVID era was similar to that in non-COVID times. These data suggest that LDLT may be extended to more stable patients with strict protocols.
Background and Aims:Fast tracking (FT) for more efficacious use of resources may be difficult after living donor liver transplantation (LDLT) due to a partial liver graft, complex vascular anastomoses and longer operating time. Our study was aimed at reporting our experience with FT (on table extubation) in LDLT recipients. A secondary objective of our study was to look at defining a subgroup of patients who could be prospectively planned for FT.Methods:We studied the demographics and outcomes of 15 LDLT recipients extubated immediately in the operating suite based on an uneventful intraoperative course, haemodynamic stability after graft reperfusion and improvement of metabolic parameters post-implantation and vascular anastomoses.Results:Twelve recipients were males, and mean age, body mass index (BMI) and Model for End Stage Liver Disease (MELD) score were 43 ± 12 years, 23 ± 3 kg/m2 and 15.5 ± 6, respectively, most were Child–Turcotte–Pugh Class B. Diabetes and hypothyroidism were present in 1 and 2 patients, respectively. Post-extubation, none required immediate re-intubation and one patient needed non-invasive ventilation for 2 h.Conclusion:Fast tracked recipients were young, with a low BMI, low MELD scores, minimal comorbidities and good immediate graft function post-reperfusion.
