Background: An increasing number of liver resections are performed laparoscopically, while laparoscopic resection of lesions in the posterosuperior segments is technically challenging. We aimed to assess the outcomes of laparoscopic and open parenchymal preserving resection of lesions in the posterosuperior segments in a randomised controlled trial.

Methods: In this multicentre, patient-blinded, superiority randomised controlled trial, patients requiring parenchymal preserving liver resection for tumours in segment 4a, 7, or 8 were enrolled at 17 centres and randomised 1:1 to laparoscopic or open surgery using a minimisation scheme stratifying for centre and lesion size.

Urachal cyst is a clinical malformation caused by failure of the allantois to obliterate during embryological development. Because of its rare presentation in adults, urachal cysts are often incorrectly diagnosed. Delay in diagnosis can cause complications such as peritonitis, fistula, sepsis, or even malignant manifestation.

Background: The purpose of this study was to compare 3-year overall survival after simultaneous portal (PVE) and hepatic vein (HVE) embolization versus PVE alone in patients undergoing liver resection for primary and secondary cancers of the liver.

Methods: In this multicentre retrospective study, all DRAGON 0 centres provided 3-year follow-up data for all patients who had PVE/HVE or PVE, and were included in DRAGON 0 between 2016 and 2019. Kaplan-Meier analysis was undertaken to assess 3-year overall and recurrence/progression-free survival.

Article Synopsis
  • The study aimed to compare the outcomes of laparoscopic and open major liver resection (hemihepatectomy) primarily for cancer patients, focusing on functional recovery time and other health-related factors.
  • In a multicenter trial, 332 patients underwent surgery, with laparoscopic surgeries resulting in faster functional recovery (4 days vs. 5 days) and higher quality of life scores compared to open surgeries.
  • The laparoscopic approach also led to a shorter time to start adjuvant systemic therapy for cancer patients, without negatively affecting resection margin status or overall cancer outcomes.

Purpose: It is known that thermal liver ablation can induce liver hypertrophy. However, exact impact in liver volume remains unclear. The aim of this study is to assess the influence of radiofrequency or microwave ablation (RFA/MWA) on liver volume in patients with primary and secondary liver lesions.

Purpose: In the pre-clinical setting, hepatocellular bile salt accumulation impairs liver regeneration following partial hepatectomy. Here, we study the impact of cholestasis on portal vein embolization (PVE)-induced hypertrophy of the future liver remnant (FLR).

Methods: Patients were enrolled with perihilar cholangiocarcinoma (pCCA) or colorectal liver metastases (CRLM) undergoing PVE before a (extended) right hemihepatectomy.

Background: Many patients with bi-lobar liver tumours are not eligible for liver resection due to an insufficient future liver remnant (FLR). To reduce the risk of posthepatectomy liver failure and the primary cause of death, regenerative procedures intent to increase the FLR before surgery. The aim of this systematic review is to provide an overview of the available literature and outcomes on the effectiveness of simultaneous portal and hepatic vein embolization (PVE/HVE) versus portal vein embolization (PVE) alone.

Background And Aims: The DRAINAGE trial was a randomized controlled trial comparing preoperative endoscopic (EBD) and percutaneous biliary drainage (PTBD) in patients with potentially resectable, perihilar cholangiocarcinoma (pCCA). The aim of this study was to compare the long-term outcomes.

Methods: Patients were randomized in four tertiary referral centers.

Background: This study evaluates the effect of preoperative macrogol on gastrointestinal recovery and functional recovery after liver surgery combined with an enhanced recovery programme in a randomized controlled setting.

Methods: Patients were randomized to either 1 sachet of macrogol a day, one week prior to surgery versus no preoperative laxatives. Postoperative management for all patients was within an enhanced recovery programme.
