Background/aims: Liver resection is a demanding procedure due to the risk of massive blood loss. Different instruments for liver transection are available today. The aim of this randomized clinical trial was to analyze the efficacy of three different parenchyma transection techniques of liver resection.
Methodology: A total of 60 non-cirrhotic patients undergoing hepatectomy were randomly selected for clamp crushing technique (CRUSH), ultrasonic dissection (CUSA) or bipolar device (LigaSure), n=20 in each group. All patients had liver resection under low central venous pressure anaesthesia (CVP), with ischemic preconditioning and intermittent inflow occlusion. Primary endpoints were surgery duration, transection duration, cumulative pedicle clamping time, intraoperative blood loss and blood transfusion. Secondary endpoints included the postoperative liver injury, postoperative morbidity and mortality.
Results: Overall surgery duration was 295 vs. 270 vs. 240min for LigaSure, CUSA and Clamp Crushing Technique, respectively. The transection duration was 85 vs. 52.5 vs. 40 minutes, respectively. These three different resection techniques of non-cirrhotic liver produced similar outcome in terms of intraoperative blood loss, blood transfusion, postoperative complications and mortality.
Conclusions: The Clump Crushing Technique, CUSA and Liga Sure are equally safe for resection of non-cirrhotic liver. Liver resections can be performed safely if the entire concept is well designed and the choice of dissection device does not affect the outcome of hepatectomy.

Background: Laparoscopic liver resection (LLR) is a surgical procedure with varying degrees of difficulty depending on tumor status and surgical technique. Therefore, we aimed to evaluate the relationship between surgical difficulty levels and outcomes of LLR, particularly portal vein thrombosis (PVT).
Methods: We performed LLRs in 214 patients between January 2009 and December 2022.

Background: The two-stage surgical technique of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) enables extensive liver resection and promotes future liver remnant regeneration (FLR), in part by inhibiting the Hippo signalling pathway. Its main effector, Yes-associated protein (YAP), has low intrinsic transcriptional activity and requires the transcription enhanced associated domain factor (TEAD) family members as cofactors for target gene transcription. We evaluated the intracellular localization and expression of TEAD1-4, hypothesized to regulate the activity of YAP and, consequently, liver regeneration.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was designed to increase the resectable liver volume, yet it is associated with significant mortality and morbidity rates. Recently, minimally invasive techniques have been incorporated into ALPPS, with the potential to improve the procedure's safety profile whilst maintaining efficacy.

Primary hepatic carcinosarcoma (HCS) is an extremely rare malignant tumor with carcinomatous and sarcomatous elements. Few reported cases of HCS exist, especially with sufficient records to describe imaging and pathological features, making the diagnosis, treatment, and prognosis of HCS a significant challenge for physicians. Here, we report a case of HCS with spontaneous rupture as the initial symptom in a 77-year-old elderly male who was admitted with right upper abdominal pain for 8 days.
