INTRODUCTION: Liver hemangiomas are the most common benign tumors of the liver. Most are asymptomatic and are found accidentally by ultrasonography, computed tomography or magnetic resonance imaging of the abdomen. Liver hemangiomas usually do not need any treatment. Nevertheless, symptomatic, giant hemangiomas can be indicated for surgery, embolization or thermoablation. The aim of this study was to define based on our own experience and on the literature when and what treatment option should be indicated in patients suffering from liver hemangioma...

Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%)...

Anatomical variants of the celiac trunk (CT) branches and especially these of hepatic arteries (HAs) are among the most common variants of the arterial tree. The knowledge of the wide variability in hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic, gastric, and esophageal surgery, as well as in liver transplantations. The purpose of this case report is to describe a rare variant discovered during abdominal dissection of a 74-year-old male cadaver of Greek origin, in which the common hepatic artery was absent and its branches, the proper hepatic artery (PHA) and the gastroduodenal artery (GDA) had an aberrant and separate origin...

BACKGROUND: 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 parenchyma. METHODS: We selected six types of anatomical liver resections to exemplify the use of the intrahepatic Glissonian approach to perform segment-oriented liver resections...

BACKGROUND: There are two philosophical approaches to planning liver resection for malignancy: one strives towards zero postoperative mortality by stringent selection of candidates, thus inherently limiting patients selected; the other, accepts a low yet definite postoperative mortality rate, and offers surgery to all those with potential gain in survival. The aim of this study was to retrospectively analyse an alternative and evolving strategy, and its impact on short-term outcomes. METHOD: 3118 consecutive hepatectomies performed in 2627 patients over 3 decades (1980-2011) were analysed...

The differences between the perfusion areas of portal vein and the drainage areas of hepatic vein result in the occurrence of either ischemic or congested areas after liver resection. To elucidate which factors are related to the differences between these areas of segment (S) 6 were therefore investigated. The portal-vein-based and hepatic-vein-based regional planes of S6 were defined using the region-growing and Voronoi tessellation methods in 103 consecutive patients who undergo liver resection. Finally, factors related to the difference between the perfusion and drainage areas of S6 were identified...

Colorectal cancers are common tumors in the United States and appropriate imaging is essential to direct appropriate care. Staging and treatment differs between tumors arising in the colon versus the rectum. Local staging for colon cancer is less integral to directing therapy given radical resection is often standard. Surgical options for rectal carcinoma are more varied and rely on accurate assessment of the sphincter, circumferential resection margins, and peritoneal reflection. These important anatomic landmarks are best appreciated on high-resolution imaging with transrectal ultrasound or MRI...

Introduction: In the modern context of multimodal treatment strategies for cancer patients with systemic disease, the dogma that surgery has a limited role is becoming less and less valid. Although a "œcurative" approach is not possible for the majority of the cases, however, some patients with limited systemic disease and favorable tumor biology could benefit from an aggressive combined cytotoxic and surgical strategy. CASE REPORT: A 48-year-old patient was diagnosed with an invasive ductal carcinoma with the immunohistochemistry positive for estrogen and progesterone receptors, positive Her2 and three liver metastases...

BACKGROUND: Chronic granulomatous disease (CGD), a rare inherited disorder, is characterized by impaired ability of phagocytic cells to kill certain bacteria and fungi. Although liver abscess is a common manifestation of CGD, its optimal management in these patients is unknown. Here, we present a case of successful hepatectomy for hepatic abscess in a patient with CGD. CASE PRESENTATION: An adolescent patient with previously diagnosed CGD presented to the pediatrics department of our institution with fever...

BACKGROUND: When hepatocellular carcinoma (HCC) was located in segment 2 (S2), segment-oriented hepatectomy was more beneficial than left lateral sectionectomy as this type of anatomical resection preserved the volume of the nontumor-bearing segment. Herein, we presented 2 cases (1 with video) of laparoscopic anatomical S2 segmentectomy by the Glissonian approach. METHODS: The first patient was a 69-year-old woman, who had an incidentally detected liver nodule on abdominal ultrasound for systemic surveillance for her breast cancer...

INTRODUCTION: Colorectal liver metastases develop in 50% of patients diagnosed with colorectal cancer. Surgical resection for colorectal liver metastasis typically involves either anatomical resection (AR) or parenchymal-sparing hepatectomy (PSH). The objective of the current study was to analyze data on parenchymal versus non-parenchymal-sparing hepatic resections for CLM. METHODS: A systematic review of the literature regarding parenchymal-sparing hepatectomy was performed...

BACKGROUND: Intraoperative blood loss is one of the predictors of outcome of open hepatectomy. But the impact of blood loss in laparoscopic hepatectomy (LH) on postoperative outcomes is poorly understood. The aim of this study is to analyze the association between blood loss and postoperative outcomes after LH. METHODS: A retrospective analysis of prospectively maintained database of patients undergoing LH from 1995 to 2016 was performed. The data were divided into two groups based on the extent of blood loss: Group 1 (<250 ml) and Group 2 (≥250 ml)...

To perform accurate hepatectomy without injury, it is necessary to understand the anatomical relationship among the branches of Glisson's sheath, hepatic veins, and tumor. In Japan, three-dimensional (3D) preoperative simulation for liver surgery is becoming increasingly common, and liver 3D modeling and 3D hepatectomy simulation by 3D analysis software for liver surgery have been covered by universal healthcare insurance since 2012. Herein, we review the history of virtual hepatectomy using computer-assisted surgery (CAS) and our research to date, and we discuss the future prospects of CAS...

BACKGROUND: Laparoscopic hepatectomy for hepatocellular carcinoma (HCC) located in segment VI, VII, or VIII of the liver is usually difficult because of poor operative exposure, due to the unique anatomical structure. In this study, we evaluated the practice of laparoscopic hepatectomy with the left jackknife position for patients with HCC located in segment VI, VII, or VIII. METHODS: A total of 10 patients were enrolled to undergo laparoscopic hepatectomy with the left jackknife position...

BACKGROUND: Only approximately one in ten pancreas cancer patients is a candidate for potentially curative resection of this disease. Even this small fraction of patients has a poor prognosis following pancreatico-duodenectomy. The disease has an anatomic location that makes it difficult for the surgeon to maintain adequate margins of resection and prevent tumor spillage at the time of resection. Also, the disease is biologically aggressive and even with a complete visible resection of the disease, micrometastases are likely to remain behind...

BACKGROUND: Cholangiocarcinomas (CCAs) are aggressive malignancies that display features of biliary differentiation. According to their anatomical location, CCAs are commonly classified as intrahepatic and extrahepatic tumors, the latter entity being further subdivided into perihilar CCAs, also termed as Klatskin tumors, and distal tumors. While a majority of CCAs occur sporadically, established risk factors such as liver fluke infestation or primary sclerosing cholangitis exist. SUMMARY: Due to lack of efficient early screening markers, CCAs are frequently diagnosed at an advanced stage when curative surgical resection is not an option...
