Laparoscopic liver resection (LLR) for large malignant tumors can be technically challenging. Data on this topic are scarce, and many question its feasibility, safety, and oncologic efficiency. This study aimed to assess outcomes of LLR for large (≥5 cm) and giant (≥10 cm) malignant liver tumors. A prospectively collected database of 422 LLRs was reviewed(More)
BACKGROUND Hyperammonemic encephalopathy is a potentially fatal condition that may progress to irreversible neuronal damage and is usually associated with liver failure or portosystemic shunting. However, other less common conditions can lead to hyperammonemia in adults, such as fibrolamellar hepatocellular carcinoma. Clinical awareness of hyperammonemic(More)
OBJECTIVE This study compares the Glissonian approach with the standard approach to laparoscopic liver resection for safety and efficacy. BACKGROUND The standard laparoscopic approach to anatomic liver resection is the dissection of the elements of the Glissonian pedicle below the hilar plate. In contrast, the Glissonian approach identifies the(More)
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows R0 resection even for patients with extremely small future liver remnants. The ALPPS procedure was initially described for two-stage right trisectionectomy. Reversal ALPPS is a denomination in which the future liver remnant is the right posterior section of the liver.(More)
BACKGROUND Laparoscopic ALPPS (Associating Liver Partition and Portal vein ligation for Staged hepatectomy) has previously been reported but has been the authors' default option since 2015 in patients with small future liver remnant. METHODS A retrospective analysis of all consecutive patients undergoing ALPPS at a single referral center was performed(More)
Enucleation of hepatic tumors is a low-morbidity technique with adequate oncological results that is useful in many clinical settings. Compared with anatomical liver resections, it offers the advantage of maximal hepatic parenchymal preservation. However, some technical adversities may occur during the enucleation of liver tumors, such as difficulty in(More)
Surgical resection is the treatment of choice for malignant liver tumours. Nevertheless, surgical approach to tumours located close to the confluence of the hepatic veins is a challenging issue. Trisectionectomies are considered the first curative option for treatment of these tumours. However, those procedures are associated with high morbidity and(More)

One of the main criticisms of laparoscopic liver resection is that it is difficult, or not possible, to perform liver-sparing resections. Our aim was to present short videos where the intrahepatic Glissonian approach was used to perform anatomical liver segmental resections, instead of a larger operation, to avoid unnecessary sacrifice of the liver(More)
Modern liver techniques allowed the development of segment-based anatomical liver resections. Nevertheless, there is still a place for nonanatomical liver resections. However, in some cases, there is a need for enucleation of deep located liver tumors. The main problem with enucleation of a liver tumor deeply located in the middle of the liver is the(More)
