Article Synopsis
- The study investigates how the length of time taken during liver surgeries affects the likelihood of postoperative complications in patients undergoing different types of liver resections.
- A total of 5,424 patients were analyzed from multiple centers between 2000 and 2022, focusing on procedures like right hemihepatectomy, technically major resection, and left lateral sectionectomy.
- Results show that patients in the longest operative time group had a significantly higher risk of complications, particularly in various surgical approaches like open, laparoscopic, and robotic surgeries.
Background: It is well known that laparoscopic liver surgery can offer advantages over open liver surgery in selected patients. However, what type of procedures can benefit most from a laparoscopic approach has been investigated poorly thus far. The aim of this study is thus to define the extent of advantages of laparoscopic over open liver surgery for lesions in the anterolateral (AL) and posterosuperior (PS) segments.

The aim of this study was to assess the feasibility and oncological safety of laparoscopic right hepatectomy for colorectal liver metastases after portal vein embolization.
Methods: This was an international retrospective multicentre study of patients with colorectal liver metastases who underwent open or laparoscopic right and extended right hepatectomy after portal vein embolization between 2004 and 2020.
Article Synopsis
- A study was conducted to compare the perioperative outcomes of robotic liver surgery (RLS) and laparoscopic liver surgery (LLS) across various healthcare settings from 2009 to 2021.
- The results showed that RLS had better outcomes in terms of "textbook outcomes," lower blood loss, fewer complications, and shorter operative times compared to LLS after matching patient groups for bias.
- Despite the higher costs generally associated with robotic surgery, this study suggests that RLS may offer specific clinical advantages over LLS in minimally invasive liver procedures.
Trends in the characteristics and perioperative outcomes of patients undergoing laparoscopic and open resections for benign liver lesions: An international multicenter retrospective cohort study of 845 patients.

Article Synopsis
- The study examines the effects of increasing laparoscopic liver surgery on patients with solid benign liver lesions (BLL) across multiple medical centers globally.
- It analyzes patient outcomes over three time periods (2008-2019), noting a stable percentage of surgeries for benign conditions but an increase in laparoscopic procedures and a decrease in hospital stay length.
- Despite no significant change in overall surgical success rates (TOLS), there was a notable improvement in a more stringent success measure (TOLS+) over time, indicating better perioperative outcomes for these patients.
Background: The use of a simultaneous resection (SIMR) in patients with synchronous colorectal liver metastases (sCRLM) has increased over the past decades. However, it remains unclear when a SIMR is beneficial and when it should be avoided. The aim of this retrospective cohort study was therefore to compare the outcomes of a SIMR for sCRLM in different settings, and to assess which factors are independently associated with unfavorable outcomes.

- This study investigates the safety and effectiveness of minimally invasive liver surgery (MILS) in obese patients compared to non-obese patients, due to limited evidence on the topic.
- A total of 9,963 patients were analyzed from 20 hospitals across eight countries, revealing that obese patients faced more complications and longer surgeries than non-obese patients.
- The results indicated that MILS led to better outcomes than open liver surgery (OLS) for both groups, showing reduced blood loss, fewer complications, shorter hospital stays, and stable rates of severe morbidity and mortality over time as MILS use among obese patients increased.
