Timely diagnosis and management of pediatric acute liver failure (PALF) is of paramount importance to improve survival. The Indian Society of Pediatric Gastroenterology, Hepatology, and Nutrition invited national and international experts to identify and review important management and research questions. These covered the definition, age appropriate stepwise workup for the etiology, non-invasive diagnosis and management of cerebral edema, prognostic scores, criteria for listing for liver transplantation (LT) and bridging therapies in PALF. Statements and recommendations based on evidences assessed using the modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) system were developed, deliberated and critically reappraised by circulation. The final consensus recommendations along with relevant published background information are presented here. We expect that these recommendations would be followed by the pediatric and adult medical fraternity to improve the outcomes of PALF patients. [ABSTRACT FROM AUTHOR]

Objective: This study aimed at studying the challenges and outcomes of live-donor liver transplantation (LDLT) for pediatric acute liver failure (PALF). Study design: A total of 315 patients with PALF were treated over a period of 11 years. 42 underwent LT (41 LDLT and one DDLT), constituting 38% (41/110) of all pediatric transplants during this duration. The outcomes of LDLT for PALF were analyzed. Results: All the 41 children who underwent LT met the Kings College criteria (KCC). The etiology was indeterminate in 46.3% (n = 19) children. 75.6% (n = 31) were on mechanical ventilation for grade 3/4 hepatic encephalopathy. There was presence of cerebral edema on a computed tomography scan of the brain in 50% of the children. One-third of our children required hemodynamic support with vasopressors. Systemic inflammatory response syndrome and sepsis were observed in 46.3% and 41.4% of patients, respectively. Post-LDLT 1- and 5-yr patient and graft survival were 75.6% and 70.9%, respectively. The survival in children satisfying KCC but did not undergo LT was 24% (38/161). Vascular and biliary complication rates were 2.4% and 4.8%, respectively. No graft loss occurred because of acute rejection. In multivariate analysis, pre-LT culture positivity and cerebral edema, persistence of brain edema after transplantation, and resultant pulmonary complications were significantly associated with post-LT death. Thirteen (32%) children who underwent plasmapheresis prior to LT had better post-LT neurological recovery, as evidenced by early extubation. Conclusion: LDLT for PALF is lifesaving and provides a unique opportunity to time transplantation. Good long-term survival can be achieved, despite the majority of patients presenting late for transplantation. Early referral and better selection can save more lives through timely transplantation.

Introduction: The current study aimed to assess the safety of early drain removal after live donor hepatectomy (LDH). Methods: One hundred eight consecutive donors who met the inclusion criteria were randomized to early drain removal (EDR — postoperative day (POD) 3 — if serous and the drain bilirubin level was less than 3 mg/dl — "3 × 3" rule) and routine drain removal (RDR — drain output serous and less than 100 ml). The primary outcome was to compare the safety. The secondary outcome was to compare the postoperative morbidity. Results: Preoperative, intraoperative, and postoperative parameters except for the timing of drain removal were comparable. EDR was feasible in 46 out of 54 donors (85.14%) and none required re-intervention after EDR. There was significantly better pain relief with EDR (p = 0.00). Overall complications, pulmonary complications, and hospital stay were comparable on intention-to-treat analysis. However, pulmonary complications (EDR — 1.9% vs RDR — 16.3% P = 0.030), overall complications (18.8% vs 36.3%, P = 0.043), and hospital stay (8 vs 9, P = 0.014) were more in the RDR group on per treatment analysis. Bile leaks were seen in three donors (3.7% in the EDR group vs 1.9% in RDR, P = 0.558), and none of them required endo-biliary interventions. Re-exploration for intestinal obstruction was required for 3 donors in RDR (0% vs 5.7%; p = 0.079). Conclusion: EDR by the "3 × 3" rule after LDH is safe and associated with better pain relief. On per treatment analysis, EDR was associated with significantly less hospital stay and lower pulmonary and overall complications. Clinical trial registry: Clinical Trials.gov — NCT04504487.

Background: Hepatic artery–related complications (HARC) after live donor liver transplantation (LDLT) is associated with high morbidity and mortality rate. Methods: Prospectively maintained data from July 2011 to September 2020 was analyzed for etiology, detection, management, and outcome of HARC. Results: Six hundred fifty-seven LDLT (adult 572/pediatrics 85) were performed during the study period. Twenty-one (3.2%) patient developed HARC; 16 (2.4%) hepatic artery thrombosis (HAT) and 5 (0.76%) non-thrombotic hepatic artery complication (NTHAC). Ninety percent (19/21) HARC were asymptomatic and detected on protocol Doppler. Median time to detection was day 4 (range − 1 to 35), which included 18 early (within 7 days) vs 3 late incidents. Only one pediatric patient had HAT. Seven patients underwent surgical revascularization, 11 had endovascular intervention and 3 with attenuated flow required only systemic anticoagulation. All NTHAC survived without any sequelae. Revascularization was successful in 81% (13/16) with HAT. Biliary complications were seen in 5 (23.8%); four were managed successfully. Overall mortality was 14.8% (3/21). The 1-year and 5-year survival were similar to those who did not develop HARC (80.9% vs 84.2%, p = 0.27 and 71.4% vs 75.19%, p = 0.36 respectively) but biliary complications were significantly higher (23.8% vs 14.2%, p = 0.03). On multivariate analysis, clockwise technique of arterial reconstruction was associated with decreased risk of HAT (1.7% vs 4.1% (p value − 0.003)). Conclusion: Technical refinement, early detection, and revascularization can achieve good outcome in patients with HARC after LDLT. [ABSTRACT FROM AUTHOR]
