Background: Early allograft dysfunction (EAD) affects outcomes in liver transplantation (LT). Existing risk models developed for deceased-donor LT depend on posttransplant factors and fall short in living-donor LT (LDLT), where pretransplant evaluations are crucial for preventing EAD and justifying the donor's risks.

Methods: This retrospective study analyzed data from 2944 adult patients who underwent LDLT at 17 centers between 2016 and 2020.

Background: Given the increasing prevalence of antiplatelet agent use and the lack of high-quality evidence, the CAPTAIN trial aimed to investigate the safety and provide recommendations on continuing acetylsalicylic acid perioperatively in patients undergoing elective laparoscopic totally extraperitoneal inguinal hernia repair (LIHR).

Methods: The CAPTAIN trial was a multicentre, surgeon blind, randomized controlled trial conducted from April 2016 to April 2023. Patients undergoing LIHR were eligible for inclusion.

Article Synopsis
  • A study was conducted to compare robotic minor liver resections (RMLR) with laparoscopic minor liver resections (LMLR) in patients undergoing surgery on the anterolateral liver segments.
  • The analysis included over 10,000 patients and employed propensity score matching to balance the groups for accuracy in comparisons.
  • Results indicated RMLR had benefits like less blood loss, lower major morbidity, and shorter hospital stays than LMLR, although the difference in 30-day readmission rates suggested RMLR may have some drawbacks.

Article Synopsis
  • Indocyanine Green (ICG) is a technique used during esophageal surgery to help doctors check how well the stomach connection is healing.
  • The study looked at 1,399 patients, comparing those who had ICG assessments to those who didn't, finding that ICG may lower the chance of leaks in the stomach connection after surgery.
  • However, since there were some problems with the studies analyzed, more research is needed to be sure about how helpful ICG really is.

Background: Individual studies on men with mildly symptomatic or asymptomatic inguinal hernia who have opted for watchful waiting (WW) vary considerably. Furthermore, long-term data on such patients who cross over to herniorrhaphy is scarce.

Methods: PubMed, EMBASE, and Cochrane databases were searched systematically from inception to 3rd April 2024 for long-term follow-up of randomized controlled trials (RCTs) on men with mildly symptomatic or asymptomatic inguinal hernia.

In living-donor liver transplantation, biliary complications including bile leaks and biliary anastomotic strictures remain significant challenges, with incidences varying across different centers. This multicentric retrospective study (2016-2020) included 3633 adult patients from 18 centers and aimed to identify risk factors for these biliary complications and their impact on patient survival. Incidences of bile leaks and biliary strictures were 11.

Article Synopsis
  • The study aimed to assess the effects of lymph node dissection (LND) on patients who underwent surgery for intrahepatic cholangiocarcinoma (ICC) through a systematic review and meta-analysis.
  • Researchers analyzed various studies that compared outcomes for patients with LND versus those without, focusing on those using advanced statistical methods to minimize bias.
  • Results showed no significant differences in overall survival or complications between the two groups, except for patients with clinically node-negative ICC, who had better overall survival with LND and a potential trend towards improved disease-free survival.

Introduction: New concerns have been raised by the US Food and Drug Administration regarding breast implant capsule-associated squamous cell carcinoma (BICA-SCC) but very little is known about this emerging topic. To gain a better understanding of the disease, a systematic review and individual patient data meta-analysis of patients with BICA-SCC were performed.

Methods: PubMed, Embase, and Cochrane were searched from inception to 26th February 2023 for studies including patients with BICA-SCC.

Objective: To define benchmark values for adult-to-adult living-donor liver transplantation (LDLT).

Background: LDLT utilizes living-donor hemiliver grafts to expand the donor pool and reduce waitlist mortality. Although references have been established for donor hepatectomy, no such information exists for recipients to enable conclusive quality and comparative assessments.

Background: An updated systematic review and meta-analysis was conducted to compare radiofrequency ablation (RFA) versus repeat hepatectomy (RH) for patients with recurrent hepatocellular carcinoma (rHCC) after a previous liver resection.

Methods: PubMed, EMBASE, and Cochrane databases were searched from inception to October 2021 for randomized controlled trials and propensity-score matched studies. Individual participant survival data of disease-free survival (DFS) and overall survival (OS) were extracted and reconstructed followed by one-stage and two-stage meta-analysis.

Tietze's syndrome is a rare inflammatory disorder characterized by chest well swelling and inflammation of the costal cartilages. We describe a gentleman with repeated presentations to the emergency department (ED) with left-sided chest and sternoclavicular pain on a background of recent asymptomatic coronavirus disease 2019 (COVID-19) infection. He had elevated inflammatory markers and MRI subsequently confirmed the diagnosis of Tietze's syndrome.

Background: Evidence for use of graft from older donors in living donor liver transplantation (LDLT) has been conflicting. This study aims to clarify the impact of donor age on recipient morbidity and mortality after adult LDLT.

Methods: A total of 90 live liver donors and recipients who underwent primary adult-to-adult LDLT were divided into three groups according to donor age: donors in 20s (D-20s) group, donors in 30s and 40s (D-30s and 40s) group and donors in 50s & 60s (D-50s and 60s) group.

Background: A systematic review and network meta-analysis was performed to compare outcomes after living donor right hepatectomy via the following techniques: conventional open (Open), mini-laparotomy (Minilap), hybrid (Hybrid), totally laparoscopic (Lap), and robotic living donor right hepatectomy (Robotic).

Methods: PubMed, EMBASE, Cochrane, and Scopus were searched from inception to August 2021 for comparative studies of patients who underwent living donor right hepatectomy.

Results: Nineteen studies comprising 2,261 patients were included.

Objective: Ensuring reliable central venous access with the fewest complications is vital for cancer patients receiving chemotherapy. A systematic review and network meta-analysis was conducted to compare the safety, quality of life, and cost-effectiveness of different types of central venous access devices (CVADs) for patients receiving chemotherapy.

Methods: The PubMed, EMBASE, and Cochrane databases were searched from inception to August 20, 2021 for randomized controlled trials comparing the various CVADs (ie, nontunneled central venous catheters [CVCs], peripherally inserted CVCs [PICCs], totally implantable venous access ports [TIVAPs], and tunneled CVCs).

Background: The volume-outcome relation for complex surgical procedures such as living donor liver transplantation (LDLT) generally favors high volume (HV) centers. It is important for low to medium volume (MV) centers to evaluate their centers' performance against HV centers to allow early detection and correction of potential systemic issues. There is a dearth of national and international comprehensive registries for LDLT that may allow reasonable risk-adjusted comparisons for benchmarking.

Background: Given the complexity of living donor hepatectomy, it is expected that high hospital volume will better outcomes. This study aims to evaluate post-operative outcomes for living donor hepatectomy in a medium volume liver transplant centre and compare to outcomes in high volume centres. Also, it serves as a validation tool for framework of structure-process-outcome model for safe living donor hepatectomy program.
