BACKGROUND: Many centers consider hepatocellular carcinoma (HCC) located in segments 7 or 8 to be unsuitable for laparoscopic liver resection (LLR). We evaluated the safety of LLR of HCC in segments 7 or 8 following the introduction of new laparoscopic techniques. METHODS: This retrospective study included 104 patients who underwent LLR (n = 46) or open liver resection (OLR) (n = 58) for HCC located in segments 7 or 8 between October 2004 and June 2015. The LLR group was subdivided into two subgroups according to whether LLR was performed before (Lap1; n = 29) or after (Lap2; n = 17) the introduction of the Pringle maneuver, intercostal trocars, and semi-lateral patient positioning...

This short review summarizes the most relevant data on colorectal liver metastases (CLM) presented at the 2016 Annual Meeting of the American Society of Clinical Oncology (ASCO). For this update, congress abstracts were grouped into three clinically relevant scenarios: CLM that are deemed upfront resectable, borderline resectable, and primarily unresectable. According to a large registry study, small, upfront resectable, solitary CLM should be resected using a parenchymal sparing technique. A prospective noninterventional study suggested that chemotherapy plus the anti-VEGF (vascular endothelial growth factor) antibody bevacizumab is effective and well tolerated in patients with borderline resectable CLM...

Colorectal cancer is one of the most common malignancies. The liver is the most common site of distant metastasis, and liver metastasis is the leading cause of death in the patients with colorectal cancer. In recent years, the concept of diagnosis and treatment in colorectal liver metastasis (CLM) and the liver surgery techniques developed rapidly, the standardization of clinical practice elevated obviously, and the survival outcomes of more and more patients were significantly improved. Standardization of diagnosis and treatment in CLM comprised overall assessment of patients' condition and local tumor status based on multidisciplinary team collaboration and then institution of treatment strategy...

BACKGROUND: Despite modern surgical techniques, insufficient hemostasis after liver trauma is still a major cause of morbidity and mortality after injury. Therefore, efficient hemostatic agents are indicated. In this study, we evaluated the hemostatic efficacy of a novel synthetic wound adhesive (MAR-VIVO-107) based on polyurethane/polyurea, compared with a widely used fibrin adhesive (Tisseel). MATERIALS AND METHODS: Twelve German Landrace pigs were randomly assigned to 2 groups...

BACKGROUND: Traditionally, open hepatic resection is the first choice of treatment for symptomatic enlarging hepatic hemangiomas, which requires a large abdominal incision and is associated with substantial recovery time and morbidity. Minimally invasive laparoscopic resection has been used recently in liver surgery for treating selected hepatic hemangiomas. However, laparoscopic liver surgery poses the significant technical challenges and high rate of conversion. Radiofrequency (RF) ablation has been proved feasible in the treatment of hepatic hemangiomas with a size range of 5...

BACKGROUND: Uncontrolled introduction of laparoscopic liver surgery (LLS) could compromise postoperative outcomes. A stepwise introduction of LLS combined with structured training is advised. This study aimed to evaluate the impact of such a stepwise introduction. METHODS: A retrospective, single-center case series assessing short term outcomes of all consecutive LLS in the period November 2006-January 2017. The technique was implemented in a stepwise fashion. To evaluate the impact of this stepwise approach combined with structured training, outcomes of LLS before and after a laparoscopic HPB fellowship were compared...

BACKGROUND AND OBJECTIVES: Portal vein (PV) territory identification during liver resection may be performed using indocyanine green (ICG) fluorescence imaging technique. However, the technical details of the fluorescence staining technique have not been fully elucidated. This study was performed to demonstrate the technical details of PV territory identification using fluorescence imaging and evaluates the short-term outcomes. METHODS: From 2011 to 2015, 105 underwent liver resection at the University of Tokyo Hospital with one of the following fluorescence staining techniques by transhepatic PV injection or intravenous injection of ICG: single staining (n = 36), multiple staining (n = 31), counterstaining (n = 22), negative staining (n = 13), or paradoxical negative staining (n = 3)...

Primary liver cancer, mainly hepatocellular carcinoma, is one of the most common malignancies worldwide. Surgical management, either resection or transplantation, is considered definitive treatment, however, less than 20% of patients are ultimately candidates. Thermal ablation modalities such as radiofrequency ablation and microwave ablation have evolved such that these modalities have been applied with curative intent. Moreover, thermal ablation has demonstrated efficacy in treating early-stage tumors and can be offered as first-line treatment in patients with uncomplicated disease...

BACKGROUND: Improved resection techniques has decreased mortality rate following liver resections(LRx). Sealants are known as effective adjuncts for haemostasis after LRx. We compared biliostatic effectiveness of two sealants in a standardized porcine model of LRx. MATERIAL AND METHODS: We accomplished left hemihepatectomy on 27 pigs. The animals were randomized in control group(n = 9) with no sealant and treatment groups (each n = 9), in which resection surfaces were covered with TachoSil(®) and TissuFleece(®)/Tissucol Duo(®)...

BACKGROUND: Hepatic resection is the only potentially curative treatment for primary liver tumors and hepatic metastases. The most frightening postoperative complication of extensive hepatectomies is liver failure due to insufficient future liver remnant (FLR). The ALPPS technique (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) effectively increased the resectability of otherwise inoperable liver tumors (primary or secondary malignant liver tumor) by achieving a rapid and an effective hypertrophy of the FLR, which lowers postoperative liver failure risk...

Background: Liver resection (LR) is the treatment of choice for most benign and malignant focal liver lesions, as well as in selected patients with liver trauma. Few other therapies can compete with LR in selected cases, such as liver transplantation in hepatocellular carcinoma (HCC) and ablative therapies in small HCCs or liver metastases. The present paper analyses a single center experience in LR, reviewing the indications of LR, the operative techniques and their short-term results. MATERIAL AND METHOD: Between January 2000 and December 2016, in "œDan Setlacec" Center of General Surgery and Liver Transplantation were performed 3165 LRs in 3016 patients, for pathologic conditions of the liver...

BACKGROUND: Only a few studies have reported the resection and reconstruction of major hepatic veins during hepatectomy. Here we present our strategy and techniques for venous reconstruction with cryopreserved homologous veins, and describe the surgical outcome. METHODS: Among 2387 hepatectomy patients, 39 patients who required hepatic venous reconstruction were reviewed retrospectively. Venous reconstruction was performed to secure a non-congested liver remnant volume of at least 40% of the total liver volume...

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a recently introduced technique aimed to perform two-stage hepatectomy in patients with a variety of primary or secondary neoplastic lesions. ALPSS is based on a preliminary liver resection associated with ligation of the portal branch directed to the diseased hemiliver (DH), followed by hepatectomy after an interval of time in which the future liver remnant (FLR) hypertrophied adequately (partly because of preserved arterialization of the DH)...

Colorectal cancer remains a leading cause of cancer-related death in Europe. Approximately one-quarter of patients have synchronous hepatic metastases and metachronous liver metastases occur in a further 30%. The scope of surgery in management of colorectal metastases has evolved to include selected patients with extra-hepatic disease for whom R0 resection is considered feasible; however, locoregional treatments are increasingly recognised as viable management options in those patients deemed unsuitable for surgery and there is an expanding body of evidence regarding their ability to achieve local control and increase progression-free survival in the liver...

INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50...

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision...

BACKGROUND: Surgical management of centrally located hepatocellular carcinoma (CL-HCC) poses a great challenge. Major hepatectomy (MH) might compromise future remnant liver volume (FRLV), while the long-term benefits of central hepatectomy (CH) had not been well demonstrated. METHODS: Consecutive patients with early-stage CL-HCC who underwent liver resection were enrolled. Fifteen patients underwent CH, while thirty-three were subjected to MH. All relevant clinicopathological variables were analyzed...
