We conducted a retrospective cohort study analyzing patients who underwent LLR for lesions located in the PS segments.

Impact of body mass index on perioperative outcomes of laparoscopic major hepatectomies.

Background: Data on the effect of body mass index on laparoscopic liver resections are conflicting. We performed this study to investigate the association between body mass index and postoperative outcomes after laparoscopic major hepatectomies.

Methods: This is a retrospective review of 4,348 laparoscopic major hepatectomies at 58 centers between 2005 and 2021, of which 3,383 met the study inclusion criteria.

The value of analyzing textbook outcomes after laparoscopic hepatectomy-a narrative review.

Background And Objective: Guidelines are required because of the wide variability in care provided to patients with similar characteristics and similar medical conditions. Quality indicators were developed many years ago to assess the quality of care provided by hospitals. Since then, it has become evident that a composite set of factors can better characterize the patient's quality of care.

An international multicentre propensity score matched analysis comparing between robotic versus laparoscopic left lateral sectionectomy.

Background: Left lateral sectionectomy (LLS) is one of the most commonly performed minimally invasive liver resections. While laparoscopic (L)-LLS is a well-established technique, over traditional open resection, it remains controversial if robotic (R)-LLS provides any advantages of L-LLS.

Methods: A post hoc analysis of 997 patients from 21 international centres undergoing L-LLS or R-LLS from 2006 to 2020 was conducted.

This study aimed to compare the perioperative outcomes and survival after LH versus open hepatectomy (OH) in large HCC patients.

Methods: An analysis of prospectively maintained database included 215 hepatectomies for large HCC (diameter ≥ 5 cm).

Incidence, risk factors, and outcomes of jejunal varix of the afferent loop after pancreatoduodenectomy.

Background: Jejunal varix is a concerning late complication after pancreatoduodenectomy (PD) due to the risk of recurrent and intractable bleeding. Our aim was to investigate the incidence, risk factors, and outcomes of jejunal varix after PD.

Methods: A total of 709 patients who underwent PD between 2007 and 2017 were included.

Defining Global Benchmarks for Laparoscopic Liver Resections: An International Multicenter Study.

Objective: To establish global benchmark outcomes indicators after laparoscopic liver resections (L-LR).

Background: There is limited published data to date on the best achievable outcomes after L-LR.

Methods: This is a post hoc analysis of a multicenter database of 11,983 patients undergoing L-LR in 45 international centers in 4 continents between 2015 and 2020.

Association between achieving textbook outcomes and better survival after laparoscopic liver resection in the anterolateral segments in patients with hepatocellular carcinoma.

Background: The quality of surgical procedures are assessed by textbook outcomes (TO). Laparoscopic liver resection (LLR) is considered a standard treatment for hepatocellular carcinoma (HCC) in the anterolateral segments of the liver. The main objective of this study was to evaluate the factors affecting achievement of TO for LLR and its impact on survival.

Long-term surgical outcomes of Non alcoholic fatty liver disease associated hepatocellular carcinoma.

Background: The global burden of non-alcoholic fatty liver disease (NAFLD) and NAFLD-associated hepatocellular carcinoma (HCC) is steadily rising. We pursued to investigate the results after liver resection for NAFLD-HCC versus hepatitis B virus (HBV)-HCC exploiting Kaplan Meier method, log-rank test and uni/multivariate analysis with the logistic regression models".

Methods: Patients who underwent liver resection for HCC between January 2004 and December 2018 were included.

Nontumor related risk score: A new tool to improve prediction of prognosis after hepatectomy for colorectal liver metastases.

Background: Prognostic stratification of patients with colorectal cancer liver metastasis based solely on tumor-related factors has only moderate discriminatory ability. We hypothesized that the inclusion of nontumor related factors can improve prediction of long-term prognosis of patients with colorectal cancer liver metastasis.

Methods: Nontumor related laboratory markers were assessed utilizing a training cohort from 2 U.

Pathological prognostic factors for post-resection survival in patients with hepatocellular carcinoma associated with non-alcoholic fatty liver disease.

Background: The incidence of hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD) is steadily increasing. However, little is known about the characteristics of these patients or the factors affecting their prognosis. Our aim was to evaluate the pathological prognostic factors associated with survival in NAFLD patients.

Achievement of textbook outcomes and comparisons with benchmark values after laparoscopic left lateral sectionectomy.

Laparoscopic left lateral sectionectomy (LLLS) is considered a standard approach for patients. Textbook outcomes (TOs) with benchmark values have been developed to help centers assess their outcomes of LLLS. The aim of our study was to identify factors associated with achieving TOs after LLLS.

Diagnosis and surgical treatment of a rare hepatic angiomyolipoma with internal hemorrhage.

Although angiomyolipoma (AML) is commonly found in the kidney, its appearance in the liver is rare. The first hepatic AML was reported by Ishak in 1976. Since then, there have been various reports of AML.

Comparative Study of Laparoscopic Versus Open Liver Resection in Gallbladder Cancer.

In recent decades, laparoscopic liver resection (LLR) has been gradually adopted at high-volume centers, particularly for hepatocellular carcinoma and liver metastasis. However, LLR in patients with gallbladder cancer (GBC) is a controversial issue, and there are few studies of LLR for GBC. Our aim was to compare the outcomes of patients who underwent laparoscopic or open liver resection for GBC.

Association between oncological outcomes of patients with colorectal liver metastasis and additional gadoxetic acid-enhanced magnetic resonance imaging.
