The aim of this study is to present the outcome of operative and non-operative management of patients with liver injury treated in a single institution depending on imaging. This study was conducted at the Causality Unit of Minia University Hospital, and included 60 patients with hepatic trauma from March 2012 to January 2013. In our study, males represent 80 % while females represent 20 % of the traumatized patients. The peak age for trauma found was 11-30 years. Blunt trauma is the most common cause of liver injury as it was the cause in 48 patients (80 %)...

BACKGROUND: Colorectal cancer (CRC) often presents as oligometastatic disease. Currently available intensive systemic treatment regimens, including combination chemotherapy and molecular targeted agents, result in tumor response and transient to long-term disease control in a high percentage of patients, thus raising the question of further management. Secondary resection and ablation, e.g. by surgery or radiofrequency may contribute to long-term survival and even be curative or at least allow a relevant chemotherapy-free interval...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy after hepatocellular carcinoma. Complete surgical resection remains the only potentially curative option for patients with ICC. However, until now, early diagnosis with potential surgical intervention has been the exception rather than the rule with only 30% of patients qualifying for attempted surgical cure. Many patients are unresectable because of disease stage, anatomic conditions, medical comorbidities, and small future remnant liver...

Anatomical resection (AR) is superior to nonanatomical resection (NAR) in theory, but the actual clinical benefit of AR for hepatocellular carcinoma (HCC) is controversial due to the substantial heterogeneity of HCC. Here, we retrospectively compared AR and NAR outcomes for solitary hepatocellular carcinoma (HCC) <5 cm in the right posterior section (RPS) and investigated the risk factors for HCC recurrence and liver-related mortality.The study included 99 consecutive patients who underwent curative surgical resection of an HCC in the RPS (S6 and S7) between January 2003 and December 2009...

BACKGROUND: The portal pedicles are wrapped in connective tissue known as the Walaeus sheath, which abut Laennec's capsule covering the liver parenchyma. Precise knowledge of this anatomic relationship allows for dissection of this interspace and early control of the segmental portal pedicle (Glissonean pedicle transection method [GPTM], Takasaki approach). (1,2) Subsequent systemic administration of indocyanine green (ICG) leads to negative counterstaining of the segment to be resected...

OBJECTIVE: To present technical details for central hepatectomy and right anterior and posterior sectionectomies using perihilar Glissonian approach for anatomical delineation and selective inflow occlusion. BACKGROUND: Central tumors and those deeply located in the right liver may require extensive resections because of their proximity to major vascular structures. In such cases, anatomical more limited resections such as central hepatectomy or sectionectomies may provide an alternative to extensive surgery by assuring both parenchymal sparing and suitable oncologic resection...

INTRODUCTION: Laparoscopic liver resection (LLR) has been widely performed throughout the world. Although prospective registry studies to clarify the safety of LLR have been feasible, no prior multicenter prospective study has addressed this issue. We have conducted a multicenter prospective cohort study to reveal the current status of LLR in Japan. METHODS: From April 2015 to March 2016, candidates for LLR were preoperatively enrolled at 12 institutions. The primary end-point was surgical safety, which was evaluated based on surgical factors and on short-term and midterm outcomes...

Liver metastases from colorectal carcinoma commonly form nodular lesions in the liver parenchyma. We report a case of liver metastasis from rectal adenocarcinoma that extended predominantly into the bile duct. A 62-year-old Japanese man underwent low anterior resection for rectal adenocarcinoma 9 years ago. Approximately 3 years later, he underwent radiofrequency ablation therapy for a metastatic liver tumor. Nine years after surgery, a tumor in liver segment III exhibiting intrabiliary extension was discovered; it was unclear if this was a metastatic liver tumor or intrahepatic cholangiocarcinoma...

Currently surgical resection is still the best therapeutic method to treat hepatocellular carcinoma, but the effects of different surgical methods on postoperative recurrence of hepatocellular carcinoma are still controversial. According to the technical points and developmental course of anatomical and non-anatomical hepatectomy, this paper analyzes the published literature and draws a conclusion that success of hepatectomy depends on exact balance between residual liver reserve function and radical resection of tumor...

BACKGROUND: Severe blunt hepatic injury is a major cause of morbidity and mortality in pediatric patients. Damage control (DC) surgery has been reported to be useful in severely compromised children with hepatic injury. We applied such a technique in the treatment of a case of hemodynamically unstable grade IV blunt hepatic injury in an eight-year-old girl. This case is the first to use multimodal approaches including perihepatic packing, temporary closure of the abdominal wall with a plastic sheet, transarterial embolization (TAE), and planned delayed anatomical hepatic resection in a child...

BACKGROUND: Curative hepatectomy with bile duct resection is the treatment for perihilar cholangiocarcinoma. A locally advanced tumor necessitates hepatectomy with simultaneous vascular resection, and reconstruction remains an obstacle for surgeons. Studies have focused on the variations of hepatic arteries. Nevertheless, the anatomical alignment of the portal veins, bile ducts, and hepatic arteries are equally critical in surgical planning of curative resection for advanced tumors. We have reported promising outcomes of hepatectomy with simultaneous resection and reconstruction of the hepatic artery...

Cholangiocellular carcinoma (CCA) is the second most frequent primary liver carcinoma and is an aggressive tumor, which is mostly diagnosed in advanced stages. The overall survival is poor. Histpathological analysis of tumor biopsies or cytological analysis of biliary brushings can be used to confirm the diagnosis. A differentiation is made between distal, perihilar and intrahepatic CCA. The anatomical position determines the diagnostic and therapeutic strategy. Before diagnostic or therapeutic measures are undertaken it is essential to resolve biliary obstruction via endoscopic stenting or percutaneous biliary drainage...

Portal vein invasion (PVI) is common in hepatocellular carcinoma (HCC) and largely contributes to tumor recurrence after radical tumor resection or liver transplantation. Vasculogenic mimicry (VM) was an independent vascular system lined with tumor cells and associated with poor prognosis of HCC. The present study was conducted to evaluate the relationship between VM and portal vein invasion. A total of 44 HCC cases receiving anatomic liver resection were included in the study and were divided into groups with and without PVI...

The risk of ischemia of segment IV after split liver resection is high. This anatomical study was done to identify the arterial blood supply and the intrahepatic distribution of liver segment IV. The anatomy of segment IV was studied in 29 livers from adult cadavers. To identify the arterial blood supply of segment IV, water and ink were injected into the various branches of the hepatic artery and the outflow through segment IV and discoloration of the liver parenchyma were observed. In 23 of the 29 livers (79...

The objective of the treatment of colorectal cancer patients with unresectable liver metastases should be clearly defined at the outset. Potentially resectable patients should be distinguished from clearly unresectable patients. In defining resectability, it is important to take into account both anatomic characteristics and patient characteristic (comorbidities, symptoms, age). According to this evaluation, treatment should be tailored to each patient. The most widely accepted standard is doublet cytotoxic regimen plus biotherapy (anti-EGFR or anti-VEGF antibodies according to RAS status, but some patients could benefit from an intensified regimen, as triplet chemotherapy ± bevacizumab, or intraarterial treatments (hepatic arterial infusion, radioembolization or chemoembolization), in order to allow resectability...
