One of the concerns specific to minimally invasive donor hepatectomy (MIDH) is the prolonged time required for graft extraction after completion of the donor hepatectomy (donor warm ischemia time [DWIT]). There has never been an objective evaluation of minimally invasive donor hepatectomy-DWIT on allograft function in living donor liver transplantation. We evaluated the effect of DWIT following robotic donor hepatectomy (RDH) on recipient outcomes and compared them with a matched cohort of open donor hepatectomy (ODH).

Article Synopsis
  • Hepatic artery complications (HACs) after pediatric liver transplantation can lead to significant health issues, and this study aims to understand how common they are, how they are managed, and what outcomes arise from these complications.
  • The research utilizes the international HEPATIC Registry, collecting data on pediatric patients under 18 who experienced HAC within the last 20 years, focusing on survival rates and treatment success.
  • Ethical approval will be obtained from all participating sites, and findings will be shared at conferences and in academic journals, with the study registered on ClinicalTrials.gov (NCT05818644).

Background: Paucity of deceased donor livers has resulted in a 10-fold rise in living donor liver transplantations (LDLTs) performed in India over the past decade. Nonetheless, number of deceased donor liver transplantation (DDLT) performed has improved with the establishment of simplified legal framework for certification of brain death and organ donation. In this study, we present our outcomes of DDLT performed at various centers, comparing their outcomes and provide a snapshot of the increasing number of DDLT across the state over the years.

Article Synopsis
  • * A Consensus Scientific committee, comprised of 106 members from 21 countries, conducted an in-depth literature review and reached recommendations regarding ideal graft-to-recipient weight ratios, monitoring portal pressure and flow, and diagnosing SFSS around postoperative day 7.
  • * The committee proposed a new 3-grade severity stratification system to help clinicians identify patients at risk for SFSS early on, suggesting that further studies are necessary to validate this system.

Background: The benefits of minimal invasive donor hepatectomy, especially for left lateral sectionectomy (LLS) have been unequivocally demonstrated. Moreover, donors in pediatric liver transplantation (LT) are usually parents who need to recover quickly to take care of the child. There are inherent limitations to conventional laparoscopic surgery including surgeon's experience with advanced laparoscopic surgery and steep learning curve which limits the wide application of minimal invasive donor hepatectomy.

Anatomical variations of left hepatic vein are observed in nearly a third of left lateral segment (LLS) donors in living donor liver transplantation. However, there is a paucity of studies and no structured algorithm for customized outflow reconstruction in LLS grafts with variant anatomy. Analysis of a prospectively collected database of 296 LLS pediatric living donor liver transplantation was done to identify different venous drainage patterns of segments 2 (V2) and 3 (V3).

Background And Aims: Recently, there has been a considerable increase in patients with nonalcoholic fatty liver disease. Availability of high-efficacy drugs for hepatitis B and hepatitis C virus (HCV) infection may have changed the disease prevalence. We aimed to study the impact of this changing epidemiology in patients undergoing liver transplantation (LT) over a 10-year period.

Background: Need for routine reconstruction of all arteries in grafts with multiple arterial inflows remains an unsettled debate. The aim of following article is to review an anatomical basis of a decision-making strategy to deal with multiple arteries in living donor liver transplantation (LDLT).

Methods: LDLT performed between August 2009-2019 were included.

Article Synopsis
  • - The study investigates the impact of left renal vein ligation (LRVL) on improving portal blood flow in liver transplantation (LT) patients who experience spontaneous lienorenal shunts (SLS), a condition that can hinder healthy portal circulation.
  • - Out of 1638 LT recipients reviewed, 28 patients (including six pediatric cases) underwent LRVL, and results showed it significantly enhanced portal blood flow, although some complications like acute kidney injury (AKI) occurred post-surgery.
  • - Overall, LRVL is deemed a safe and effective strategy for improving portal inflow in LT recipients, but further research is needed to establish comprehensive guidelines for this approach.

The impact of increasing recipient age on morbidity and mortality following living donor liver transplantation (LDLT) remains controversial. The study aims to analyze the impact of recipient age on outcomes following LDLT. Data on adult LDLTs performed between November 2009 and February 2020 were retrieved from a prospectively maintained database.

Posttransplant lymphoproliferative disease (PTLD) is the most common malignant complication after solid organ transplantation. Gastrointestinal involvement as the presentation in early PTLD can occur in 25-30% of pediatric liver transplant recipients and can be the only system involved in 20%. Recurrent gastrointestinal perforation due to resolution of PTLD is an extremely rare complication.

HCC is the second most common malignant liver tumor of childhood. It typically affects children with a median age of 10-14 yr on background hepatitis B-related liver disease and is often metastatic or locally advanced at diagnosis. Children below the age of five yr typically constitute <10% of all children with HCC.

APOLT is a suitable technique of liver transplantation in patients with ALF and some types of MLD. Portal venous steal is a problem with this procedure that leads to graft dysfunction and failure. Modulation of the portal flow to the graft and native liver can help in preventing this problem.

Background: Although laparoscopic appendectomy has some advantages over open appendectomy, the literature suggests conflicting results regarding postoperative complications for complicated appendicitis.

Methods: A retrospective review of patients with complicated appendicitis managed surgically at Meenakshi Mission Hospital and Research Center, Madurai, Tamilnadu, India was undertaken. A total of 497 patients were admitted with acute appendicitis and operated during the study period of 10 years from January 1999 to July 2009, out of which 119 (24%) patients had complicated appendicitis whereas 378 (76%) had uncomplicated acute appendicitis.
