Objective: This study aimed to compare morbidity of living donors and recipients after pure laparoscopic donor right hepatectomy (PLDRH) and open donor right hepatectomy (ODRH).
Background: Donor and recipient morbidity have not been sufficiently reported in large-scale comparisons of PLDRH and ODRH.
Methods: This retrospective study reviewed 3348 donors who underwent PLDRH (n=329) and ODRH (n=3019) and their corresponding recipients (n=3348) between January 2014 and August 2023.
Primary treatments for solitary hepatocellular carcinoma ≤ 3 cm: A systematic review and network meta-analysis.
Ann Hepatobiliary Pancreat Surg
November 2024
Article Synopsis
- This study examines the best treatment options for small solitary hepatocellular carcinoma (HCC) tumors that are 3 cm or less, focusing on the effectiveness of various interventions.
- A network meta-analysis assessed the long-term outcomes of 30 studies including surgical resection (SR), radiofrequency ablation (RFA), microwave ablation (MWA), and transarterial chemoembolization (TACE), with SR showing the best survival rates.
- The results indicate that surgical resection is the preferred first-line treatment, particularly in patients with good liver function, while more research is needed on MWA and TACE due to limited data.
Article Synopsis
- The COVID-19 pandemic significantly affected global liver transplantation (LT) and living donor programs, prompting the study to examine how these programs adapted and succeeded during this period.
- The research focused on 1201 living donor liver transplants performed at Asan Medical Center between 2020 and 2022, highlighting key patient demographics and medical outcomes.
- Despite higher than usual in-hospital mortality at 2.2%, and various challenges, the program maintained high standards of care and successful outcomes thanks to established infection control protocols and tailored surgical strategies.
Article Synopsis
- Hepatic artery thrombosis (HAT) occurs in 2.5%-8% of living-donor liver transplant patients, leading to potential graft loss, and the study focuses on understanding risk factors and reconstruction techniques for grafts with multiple hepatic arteries.
- The research analyzed 1601 patients who received right lobe grafts, finding that pretransplant hepatectomy, female donor, smaller graft-to-recipient weight ratio, and extra-anatomical reconstruction increased HAT risk, while having two hepatic arteries did not.
- Survival rates were similar between patients with one and two hepatic arteries, suggesting that reconstructing both arteries when possible might be a beneficial approach in transplant surgeries.
Purpose: Previous studies have reported that presarcopenia negatively affects rectal cancer treatment. However, most studies have analyzed patients including majority of open surgery, and the association between presarcopenia and clinical outcomes after laparoscopic rectal cancer surgery remains unclear. This study aimed to evaluate the impact of presarcopenia on the clinical and oncological outcomes after laparoscopic rectal cancer surgery.

- - The study investigated the impact of donor sex and donor-recipient sex disparity on recurrent hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) using 772 patients from a high-volume center.
- - Researchers categorized patients by donor-recipient sex pairs and found no significant differences in disease-free survival (DFS) and overall survival (OS) among the groups.
- - The conclusion indicated that neither donor sex nor the disparity between donor and recipient sex had a significant effect on HCC recurrence post-transplantation.
Article Synopsis
- The study evaluates the safety and effectiveness of mini-incision techniques for living donor liver transplants compared to traditional open surgery.
- It involved 448 donors, dividing them into two groups based on incision type: mini-incision (187 donors) and conventional (261 donors).
- Results suggest mini-incision has similar complication rates and donor safety, making it a viable alternative to open surgery.
Background: This study aimed to investigate prognostic factors of recurrence and survival associated with hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT).
Patients And Methods: This retrospective study included 161 patients with HCC with PVTT who underwent hepatectomy between January 2003 and January 2014 at the Asan Medical Center. Regression analyses were conducted to identify favorable predictive factors for overall survival (OS) and recurrence-free survival (RFS).
Delayed gastric emptying (DGE) is a common complication of liver transplantation. This study aimed to clarify the efficacy and safety of the application of an adhesion barrier for preventing DGE in living-donor liver transplantation. This retrospective study included 453 patients who underwent living-donor liver transplantation using a right lobe graft between January 2018 and August 2019, and the incidence of postoperative DGE and complications was compared between patients in whom adhesion barrier was used (n=179 patients) and those in whom adhesion barrier was not used (n=274 patients).

Ann Surg Treat Res
September 2020
Purpose: Previous studies have reported that progressive muscle loss, known as sarcopenia, has a negative impact on colon cancer treatment. However, the majority of studies have analyzed on patients undergoing open resection, and the association of sarcopenia with clinical outcomes is not clear for patients with colon cancer undergoing laparoscopic surgery. Thus, the aim of this study was to evaluate the impact of sarcopenia on clinical outcomes after laparoscopic surgery for colon cancer.
