BACKGROUND: Robotic hepatectomy has been suggested as a safe and effective management of liver disease. However, no large case series have documented the learning curve for robotic major hepatectomy. METHOD: We conducted a retrospective study for robotic major hepatectomy performed by the same operative team between January 2012 and October 2015 and evaluated the learning curve for operation time using the cumulative sum method, presented as cumulative sumoperation time...

Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed...

A 58-year-old woman was diagnosed with a sigmoid colon cancer and synchronous liver metastasis. Because an obstruction of the sigmoid colon was identified, the patient underwent sigmoidectomy. Computed tomography(CT)findings suggested possible vena cava and hepatic vein invasion. Therefore, the decision was made to offer systemic chemotherapy. The patient underwent 6 courses of chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6). After 4 courses of chemotherapy, CT scans showed a significant reduction of the liver metastasis (reduction rate of 5 0%; a partial response) and demonstrated improved exclusion of the inferior vena cava and hepatic vein...

BACKGROUND: Laparoscopic hepatectomy (LH) has now been widely performed in experienced centers. However, hepatic vein injury (HVI) during LH is especially dangerous, because it may cause conversion, air embolization, fatal hemorrhaging, or even death. MATERIALS AND METHODS: Perioperative characteristics of 4 patients who underwent LH suffering HVI were recorded, including 2 for right HVIs, 1 for middle HVI, and 1 for left HVI. Ultrasonic shears was used for liver mobilization...

The bipolar radiofrequency device (Habib®) has been recently introduced in order to reduce intraoperative bleeding for a safe hepatic resection as an alternative to the conventional tools. However, indications, perioperative findings, and outcome of the device for hepatic resections remain and deserve to be analyzed. The current study aims to analyze the feasibility of the bipolar radiofrequency device (Habib®) for hepatic resections. Information of the patients that underwent hepatic resection using with the Habib® device between 2007 and 2011 was abstracted...

INTRODUCTION: Central hepatectomy or mesohepatectomy (MH) is a complex surgical technique rarely used in children. It is indicated in central tumors to preserve functioning liver mass avoiding an extended right hepatectomy. The purpose of this article is to analyze our experience with this technique. METHODS: We reviewed five patients who underwent MH in the period from 2008 to 2014. Diagnoses were hepatoblastoma PRETEXT III (two cases), hepatic embryonal sarcoma (one case), focal nodular hyperplasia (one case), and vascular tumor with rapid growth in a newborn causing an acute liver failure, compartment syndrome, and multiple organ failure (one case)...

We report a case of curatively resected intrahepatic cholangiocarcinoma (ICC) with hepatic artery (HA) and portal vein (PV) reconstruction. A 25-year-old man was diagnosed with ICC. Computed tomography (CT) showed that the tumor had invaded the left and common hepatic duct, the right and left HA, and the main branch of the PV. Because the posterior HA was tumor free, we performed a left trisegmentectomy, PV and HA resection and reconstruction, and a hepatocholangiojejunostomy. Pathological examination revealed a tumor classification of T3, N1, M0, Stage IVB...

A 34 -year-old woman presenting with bloody stools was diagnosed with a rectal tumor. Computed tomography (CT) revealed multiple liver masses in Couinaud segments IV, V, and VII. The lesions were diagnosed as multiple liver metastases from rectal cancer. Right trisegmentectomy of the liver was considered the optimal treatment option for curative resection; however, liver volumetric examination using CT estimated that the remnant liver volume after right trisegmentectomy would be only 24.6% of the total liver volume...

We report a case of a very rare endocrine tumor of the pancreas. The patient is a 53-year-old female who has necrotizing and crusty maculopapular lesions on the upper and lower extremities and was diagnosed with bullous pemphigoid. The patient's symptoms included fatique and weight loss, and examination revealed pale sclera, angular chelitis and glossitis. Because the CA 19-9 and glucagon levels were high, and abdominal dynamic CT showed a mass in the pancreas body and metastatic lesions in the liver, the decision was made to operate...

We report two cases of cystic neoplasm of the liver with mucinous epithelium in which both ovarian-like stroma and bile duct communication were absent. The first case was a 41-year-old woman. She underwent right trisegmentectomy due to a multilocular cystic lesion, 15 cm in diameter, with papillary nodular components in the medial segment and right lobe. Histologically, arborizing papillae were seen in the papillary lesion. The constituent neoplastic cells had sufficient cytoarchitectural atypia to be classified as high-grade dysplasia...

BACKGROUND: Resection of perihilar cholangiocarcinoma involves major hepatectomy including caudate lobectomy. It is technically challenging because of the complex, intimate and variable relationship between biliary and vascular structures in the liver hilum. Resectability rates vary from 30 to 80 % and about one third of patients have microscopically involved margins. However, adequately performed resections provide 5-year survival of 30-40 % and are worth pursuing. PURPOSE: Better understanding of anatomy, better imaging, improved surgical techniques and progress in perioperative care of these patients have pushed the limits of resection of these tumours...

BACKGROUND: Liver resection represents a most effective treatment for hepatocellular carcinoma (HCC). The extent of hepatectomy for HCC involves maintaining a tricky balance between radical resection of tumors and preservation of sufficient liver parenchyma. Generally, removal of the right hepatic vein often involves resection of the whole posterior right lobe, which may prevent patients with impaired liver function from maintaining a functional reserve and could also limit the future liver remnant from curative hepatectomy...

Hepatic adenomas are benign tumors typically diagnosed in women of reproductive age, however, these tumors occur in the pediatric population although rare. We present the case of a giant hepatic adenoma in an 8-year-old female without established risk factors with progressive abdominal pain, and po intolerance, biliary obstruction, anemia, and fever. Right trisegmentectomy afforded extirpation of the 16 × 14.5 × 8.5 cm mass. The postoperative course was complicated by transient encephalopathy and a bile leak which resolved with appropriate care...

BACKGROUND: Intubated general anesthesia with one-lung ventilation is considered mandatory for anatomical pulmonary resections. Nonintubated thoracoscopic segmentectomy for management of lung tumors, which is technically challenging, has not been reported previously. The goal of this study was to evaluate the feasibility and safety of thoracoscopic anatomical segmentectomy without endotracheal intubation. METHODS: From August 2009 to December 2012, 21 patients with lung tumors were treated using thoracoscopic anatomical segmentectomy without endotracheal intubation using a combination of thoracic epidural anesthesia, intrathoracic vagal blockade, and target-controlled sedation...

BACKGROUND: Successful left lateral segment (sectionectomy) and right trisegmentectomy (trisectionectomy) split-liver transplantation (SLT) have been achieved. However, there are few reports of the use of true right/left splitting in SLT. METHODS: A single-centre retrospective review of true right/left ex vivo split-liver transplants performed during the period 1993-2010 was conducted. Nine cadaveric liver grafts underwent splitting and the resultant 18 allografts were used in transplants performed at the study centre...

BACKGROUND: Involvement of the IVC has traditionally been considered a relative contraindication to resection for advanced tumors of the liver. Combined resection of the liver and IVC for malignancy can be performed safely and results in long-term survival in select patients. STUDY DESIGN: Sixty patients undergoing hepatic and IVC resection by the primary author from 1996 to 2012 were reviewed. Median age was 52 years. Resections were carried out for cholangiocarcinoma (n = 26), hepatocellular carcinoma (n = 16), colorectal metastases (n = 13), gastrointestinal stromal tumor (n = 2), hepatoblastoma (n = 2), and squamous cell carcinoma (n = 1)...

BACKGROUND AND AIM: Hepatic resection involves not only complete removal of tumors but also preservation of optimal liver function after surgery. This study introduces the technique of inferior right hepatic vein (IRHV)-preserving trisegmentectomy 5, 7, and 8 and evaluates its clinical feasibility. METHODS: Between January 2008 and December 2011, four patients underwent this procedure. Postoperative outcomes and interim results were evaluated. RESULTS: The median estimated volumes of the left lobe only and the left lobe plus preserved parenchyma relative to the total estimated liver volume were 22...

A 59-year-old woman was admitted to our hospital for treatment of a right humerus fracture. The patient was diagnosed with hepatocellular carcinoma during work-up for hepatic dysfunction. A diffusely spreading tumor was observed from the right lobe to the medial segment of the liver, and a portal vein tumor thrombus filled the right branch of the portal vein and extended into the main trunk, accompanied by cavernous transformation (Vp4). A multidisciplinary treatment regimen including surgical intervention was planned because the patient desired aggressive treatment...
