Neuroendocrine tumors (NET) represent the variability of almost benign lesions either secreting hormones occurring as a single lesion up to malignant lesions with metastatic potential. Treatment of NET is usually performed by surgical resection. Due to the rarity of NET, surgical treatment is mainly based on the experience and recommendations of experts and less on the basis of prospective randomized studies. In addition, the development and establishment of new surgical procedures is made more difficult by their rarity...

Recent advances in surgical techniques have broadened the indications of surgical management of liver malignancies. Intraoperative bleeding is one of the known predictors of postoperative outcomes following liver surgery, signifying the importance of vascular control during liver resection. Furthermore, preservation of future liver remnant plays a critical role in prevention of post-hepatectomy liver failure as one of the main causes of postoperative morbidity and mortality. Glissonian approach liver resection offers an effective method for vascular inflow control while protecting future liver remnant from ischemia-reperfusion injury...

INTRODUCTION: The present case reports demonstrated the accompanying surgical support from hepato-biliary-pancreas (HBP) surgeons for urological surgery to secure operative safety because HBP surgeons are well experienced in dissecting techniques for mobilization of the liver or pancreas. We experienced 9 consecutive patients who underwent nephrectomy, adrenectomy or resection of retroperitoneal tumors by urological surgeons. Cardiovascular intervention was also required in cases of long tumor thrombus into the vena cava...

The lack of acceptable pharmacological approaches for restoration of the injured liver is associated with complex of mechanisms involved in hepatic regeneration and with difficulty of the target selection. The aim of this research was to study the hepatoprotective function of the extract from both the growing and regenerating liver containing a natural set of factors crucial for the hepatic restoration. Extracts from both regenerating liver of rats after 70% hepatic resection and the growing liver of neonatal pigs were obtained using own original technique...

BACKGROUND: Laparoscopic liver resections for lesions in the postero-superior segments are technically demanding due their deep location and relation with the vena cava. However, previous reports have demonstrated the feasibility and safety of these resections in centres with advanced experience in laparoscopic liver surgery. In this case series, we present our results and experience of laparoscopic parenchymal sparing liver resections of lesions in segment 8. METHODS: All patients undergoing laparoscopic liver resections of segment 8 lesions, alone or combined with other liver resections, between August 2003 and July 2016 were included...

Hepatocellular carcinoma (HCC) is one of the most common malignant tumours with a poor prognosis worldwide. While early stage tumours can be treated with curative approaches such as liver transplantation or surgical resection, these are only suitable for a minority of patients. Those with advanced stage disease are only suitable for supportive approaches and most are resistant to the conventional chemotherapy or radiotherapy. Liver cancer stem cells (LCSCs) are a small subset of cancer cells with unlimited differentiation ability and tumour forming potential...

Systematic resection of the tumor-bearing portal territory is reportedly correlated with an improved survival of patients with liver tumors, especially in hepatocellular carcinoma. Despite advances in surgical management, however, anatomic resection of deeply/centrally located tumors remains a challenging procedure not only with technical difficulty but also because of decreased hepatic functional reserve frequently observed due to underlying liver disease. In this report, we have reported a novel technique that allows a promising approach for deeply/centrally located tumors with maximizing both the surgical and oncological safety...

BACKGROUND: As minimally invasive technique becomes more popular, an increasing number of elderly patients were considered for minimally invasive liver resection (MILR). Limited physiologic reserve remains a major concern, which frequently leads surgeons to recommend nonresectional alternatives. We sought to evaluate complications and outcomes of elderly patients undergoing MILR. METHODS: Eight hundred and thirty-one patients who underwent MILR were classified into groups A, B, and C based on age [(< 70, n = 629), (70-79, n = 148), (≥ 80, n = 54) years old, respectively]...

Percutaneous treatment of hepatocellular carcinoma (HCC) encompasses a vast range of techniques, including monopolar radiofrequency ablation (RFA), multibipolar RFA, microwave ablation, cryoablation and irreversible electroporation. RFA is considered to be one of the main curative treatments for HCC of less than 5 cm developing on cirrhosis, together with surgical resection and liver transplantation. However, controversies exist concerning the respective roles of ablation and liver resection for HCC of less than 3 to 5 cm on cirrhosis...

BACKGROUND: Tumor invasion or adherence to the portal vein-superior mesenteric vein (PV/SMV) may be encountered during pancreatic surgery. In such cases, venous resection and reconstruction might be required for complete resection of the tumor. We report an innovative technique in which the graft for PV/SMV reconstruction was made with the falciform ligament. METHODS: Between May 2011 and July 2016, PV/SMV reconstruction with a falciform ligament graft was performed in 10 cases during pancreatectomy...
