Associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been successfully employed in adults to avoid potential liver insufficiency in patient with small future liver volume (FLV) when subjected to conventional right trisectionectomy. We are reporting an infant with hepatoblastoma, who underwent a technically successful ALPPS procedure with R0 resection. However he developed very early recurrence within the first month after the procedure. We present this report with a view to share our unexpected finding of early multifocal recurrence of hepatoblastoma in the residual liver after ALPPS procedure in a very young patient...

OBJECTIVE: The purpose of this study was to evaluate the safety and efficacy of hepatopancreaticoduodenectomy (HPD) for patients with biliary cancer. BACKGROUND: HPD is thought to be the only curative treatment for widespread bile duct cancer and for some advanced cases of gallbladder cancer; however, HPD has not yet been accepted as a standard operative procedure because of concerns over morbidity and mortality. METHODS: Fifty-two patients undergoing HPD were retrospectively reviewed...

BACKGROUND: 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. PATIENT: A 42-year-old woman with colorectal metastases in all segments except segment 1 underwent chemotherapy with objective response and was referred for surgical treatment...

Porcine models of extended hepatectomy and liver transplantation (LT) of reduced graft have been widely used for studying the small-for-size (SFS) syndrome and the various modalities of portal inflow modulation (PIM). However, considerable heterogeneity exists among the studies and their results. The aim of this review was to assess the main advantages and drawbacks of the different porcine models of SFS LT and SFS hepatectomy, and propose a standardized anatomical nomenclature for the various models. The MEDLINE database was searched for articles reporting porcine models of reduced graft LT or hepatectomy of more than 65%...

BACKGROUND: ALPPS (Associating Liver Partition and Portal vein ligation for Staged hepatectomy) is a new surgical approach for the treatment of liver tumors. It is indicated in cases where the future liver remnant is not sufficient to maintain postoperative liver function. We report a totally laparoscopic ALPPS with selective hepatic artery clamping. Pneumoperitoneum itself results in up to 53% of portal vein flow and selective hepatic artery clamping can reduce blood loss while maintaining hepatocellular function...

BACKGROUND: Leiomyosarcoma of vascular origin is a rare tumor, occurring mainly in the inferior vena cava (IVC). When involving the hepatic vein confluence, it often causes Budd-Chiari syndrome, and IVC removal with a complex hepatectomy is required (Mingoli in J Am Coll Surg 211:145-146, 2010; Griffin in J Surg Oncol 34:53-60, 1987; Heaney in Ann Surg 163:237-241, 1966; Fortner in Ann Surg 180:644-652, 1974). METHODS: A 57-year-old male, without previous oncological history, presented with Budd-Chiari syndrome due to a leiomyosarcoma extending to the supra-diaphragmatic IVC and involving the right and middle hepatic veins...

Although surgical resection is the only way to cure biliary tract cancer (BTC), most BTCs are unresectable by the time they are diagnosed. Chemotherapy is usually used to treat unresectable BTC, but its impact on survival is small. Here, we report the case of a 70-year-old woman with a locally advanced intrahepatic cholangiocarcinoma that was initially diagnosed as an unresectable liver metastasis from colon cancer that had invaded all of the major hepatic veins. However, the tumor was noticeably reduced after treatment with CAPOX plus bevacizumab, which is an uncommon therapy for BTC...

Portal hypertension can arise from any condition interfering with normal blood flow at any level within the portal system. Herein, we presented two uncommon cases of the portal hypertension and its treatment with brief literature review. A 71-year-old man who underwent right hemihepatectomy revealed a tumor recurrence adjacent to the inferior vena cava (IVC). After radiofrequency ablation (RFA) with lymph node dissection, he was referred for abdominal distension. The abdomen computed tomography scan showed severe ascites with a narrowing middle hepatic vein (MHV) and IVC around the RFA site...

BACKGROUND: Posthepatectomy liver failure (PHLF) is one of the most serious complications after major liver resections and an important factor in terms of perioperative morbidity and mortality. Despite many advances in the understanding and grading of PHLF, the definitions found in literature are very heterogeneous, which complicates the identification of high-risk patients. In this study we analysed the results of extended liver resections and potential risk factors for PHLF based on patient data derived from our tertiary referral centre...

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 mortality rates primarily due to post-operative liver failure. Thus, maximal preservation of functional liver parenchyma should always be attempted. We describe the isolated resection of Segment 8 for the treatment of a tumour involving the right hepatic vein and in contact with the middle hepatic vein and retrohepatic vena cava with immediate reconstruction of the right hepatic vein with a vascular graft...

INTRODUCTION: The occurrence of bile leakage (BL) is one of the major contributors to the morbidity after hepatectomy. However, the clinical risk factors associated with postoperative BL remains controversial. This study aims to further assess the risk factors for BL. EVIDENCE ACQUISITION: We comprehensively searched the electronic databases of PubMed, EMBASE, Web of Science and the Cochrane Library for studies published before October 10th, 2015. Cohort studies, case-control studies, and randomized controlled trials that examined clinical risk factors for BL were included...

PURPOSE: Post-hepatectomy liver failure (PHLF) is the major risk factor for mortality after hepatectomy. Preoperative planning of the future liver remnant volume reduces PHLF rates; however, future liver remnant function (FLR-F) might have an even stronger predictive value. In this preliminary study, we used a new method to calculate FLR-F by the LiMAx test and computer tomography-assisted volumetric-analysis to visualize liver function changes after portal vein embolization (PVE) before extended hepatectomy...

BACKGROUND: The predictive value of the Model for End-stage Liver Disease (MELD) for mortality after hepatectomy is unclear. This study aimed to evaluate whether MELD score predicts death after hepatectomy and to identify the most useful score type for predicting mortality. We hypothesized that an increase in this score is correlated with 30-day mortality in patients undergoing hepatic resection. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for hepatectomy...

Right trisectionectomy for posterior liver tumors engaging the right and middle hepatic veins may lead to post-hepatectomy liver failure if the anticipated liver remnant is small. In such patients we developed a parenchyma-sparing one-step approach, that includes extrahepatic right portal vein ligation accompanied by en bloc resection only of segments 7, 8 and 4a and resection of the right and middle hepatic veins. The technique was applied in 3 patients with normal liver function, where according to the preoperative computed tomography the volume of segments 1, 2 and 3 ranged between 17% and 20% of the total liver volume...

We report the case of a 58-year-old man referred to our hospital for liver tumor treatment. The patient had a history of neurosurgery for a meningeal hemangiopericytoma 16 years previously. Pre-operative imaging revealed a hypervascular tumor extending from Couinaud segment 4 to segment 8 of the liver, measuring 95 mm in diameter, indicating an atypical hepatocellular carcinoma. Because right trisectionectomy of the liver was considered to be high risk, living-donor liver transplantation (LDLT) was indicated...

BACKGROUND: Right-sided hepatectomy is often selected for perihilar cholangiocarcinoma, due to the anatomic consideration that "the left hepatic duct is longer than that of the right hepatic duct". However, only one study briefly mentioned the length of the hepatic ducts. Our aim is to investigate whether the consideration is correct. METHODS: In surgical study, the lengths of the resected bile duct were measured using pictures of the resected specimens in 475 hepatectomized patients with perihilar cholangiocarcinoma...
