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.
Introduction: Minimally invasive oncological resections have become increasingly widespread in the surgical management of cancers. However, the role of minimally invasive surgery (MIS) for gallbladder cancer (GBC) remains unclear. We aim to perform a systematic review and network meta-analysis of existing literature to evaluate the safety and feasibility of laparoscopic and robotic surgery in the management of GBC compared to open surgery (OS) by comparing outcomes.

- The study investigates the risk factors and outcomes related to open conversion during minimally invasive liver resections (MILR), especially in minor hepatectomies, highlighting its association with inferior results.
- Analysis was conducted on data from over 10,500 patients who underwent laparoscopic or robotic liver resections from 2004 to 2020, identifying key independent predictors for open conversion.
- Results show that patients who required open conversion experienced longer recovery times, increased blood loss, higher complications, and elevated 90-day mortality rates compared to those who had successful minimally invasive surgeries.
Article Synopsis
- Minimally invasive liver surgery has become more common over the last 30 years, especially for treating colorectal liver metastases, but the effects of neoadjuvant chemotherapy on surgical outcomes are not well understood.
- A study analyzed a large database of nearly 5,000 patients who underwent minimally invasive liver surgeries to compare outcomes between those who received neoadjuvant chemotherapy and those who did not.
- The results showed that neoadjuvant chemotherapy did not significantly affect the short-term surgical outcomes in patients undergoing these liver procedures.
Article Synopsis
- This study assessed how liver cirrhosis (LC) influences the challenges of minimally invasive liver resection (MILR), specifically for minor surgeries involving primary liver tumors in anterolateral segments.
- Conducted from 2004 to 2021 across 60 centers, the research involved 3,675 patients, with varying degrees of cirrhosis classified as Child A and Child B.
- Results indicated that patients with Child A cirrhosis faced higher risks of complications, such as increased blood loss and rates of open conversion, while those with Child B cirrhosis had longer hospital stays and more significant morbidity; overall, the severity of LC complicates the surgical process, highlighting the need for better difficulty
Article Synopsis
- Minimally invasive liver resections (MILR) can reduce blood loss and recovery time compared to traditional methods, but the impact of cirrhosis on these procedures is not fully understood.
- A study reviewed data from 2534 patients who underwent minimally invasive major liver surgeries worldwide, focusing on outcomes related to different levels of cirrhosis.
- Results showed that advanced cirrhosis leads to higher blood transfusion rates, more postoperative complications, and longer hospital stays, suggesting that cirrhosis severity should be considered in future assessments of surgical difficulty in MILR.*
Article Synopsis
- The study investigates how cirrhosis and portal hypertension (PHT) affect the complexity and outcomes of minimally invasive liver surgery in specific liver segments.
- It examines a large patient group, revealing that those with cirrhosis experienced more complications and required more blood transfusions during surgery.
- The findings suggest that the presence of cirrhosis and PHT should be considered when evaluating the difficulties and risks associated with minimally invasive liver resections.
Early vs late drain removal after pancreatic resection-a systematic review and meta-analysis.

Article Synopsis
- Reducing the incidence of clinically relevant post-operative pancreatic fistula (CR-POPF) after pancreatic surgeries has gained attention, with drain management being a key focus! -
- A study reviewed nine research papers involving 8,574 patients to compare outcomes between early drain removal (within 3 days post-surgery) and late drain removal, revealing notable benefits in the early removal group! -
- Results indicated that early drain removal significantly lowered the risk of CR-POPF and various complications, alongside reduced hospital stays, suggesting a need for more studies to confirm these results!
Background: The impact of cirrhosis and portal hypertension on perioperative outcomes of minimally invasive left lateral sectionectomies remains unclear. We aimed to compare the perioperative outcomes between patients with preserved and compromised liver function (noncirrhotics versus Child-Pugh A) when undergoing minimally invasive left lateral sectionectomies. In addition, we aimed to determine if the extent of cirrhosis (Child-Pugh A versus B) and the presence of portal hypertension had a significant impact on perioperative outcomes.

- Despite advancements in minimally invasive liver surgery, open surgeries are still common, and this study examines the factors that lead to conversions from minimally invasive techniques to open surgery during major hepatectomies.
- Data from 3880 surgical cases showed that 10.28% resulted in open conversions, with several risk factors identified, such as male sex, liver cirrhosis, and larger tumor sizes, which are linked to increased conversion risk.
- The study found that those who experienced open conversions had worse outcomes, including longer operation times and higher rates of postoperative complications, although robotic surgery had a lower conversion rate compared to laparoscopic techniques, it still led to significant challenges when conversions did occur.
Background: Presently, according to different difficulty scoring systems, there is no difference in complexity estimation of laparoscopic liver resection (LLR) of segments 7 and 8. However, there is no published data supporting this assumption. To date, no studies have compared the outcomes of laparoscopic parenchyma-sparing resection of the liver segments 7 and 8.
View Article and Find Full Text PDFBackground: Despite the rapid advances that minimally invasive liver resection has gained in recent decades, open conversion is still inevitable in some circumstances. In this study, we aimed to determine the risk factors for open conversion after minimally invasive left lateral sectionectomy, and its impact on perioperative outcomes.
Methods: This is a post hoc analysis of 2,445 of 2,678 patients who underwent minimally invasive left lateral sectionectomy at 45 international centers between 2004 and 2020.
Background: We report a single surgeon experience with laparoscopic repeat liver resection (LRLR), and analyse short-term outcomes relative to laparoscopic primary liver resection (LPLR).
Methods: Two-hundred and twenty-two laparoscopic liver resections were performed from 2012 to 2019 of which 33 were LRLR. 1:2 propensity-score matching was done to compare 32 LRLR with 64 LPLR cohort.
