Yasunari Kawabata, Hikota Hayashi, Seiji Yano, Yoshitsugu Tajima
BACKGROUND: Although hemihepatectomy with total caudate lobectomy (hemiHx-tc) is essential for the surgical treatment of hilar cholangiocarcinoma, the advantage of an anterior approach for hemiHx-tc has not been fully discussed technically; the significance of an anterior approach without liver mobilization for preventing infectious complications also remains unknown. METHODS: The liver parenchyma transection-first approach (Hp-first) technique is an early transection of the hepatic parenchyma without mobilization of the liver that utilizes a modified liver-hanging maneuver to avoid damaging the future remnant liver...

Cholangiocarcinoma (CC) is the second most common type of primary liver cancer after hepatocellular carcinoma. Surgical resection is considered the only curative treatment for CC. In general, laparoscopic liver surgery (LLS) is associated with improved short-term outcomes without compromising the long-term oncological outcome. However, the role of LLS in the treatment of CC is not yet well established. In addition, CC may arise in any tract of the biliary tree, thus requiring different types of treatment, including pancreatectomies and extrahepatic bile duct resections...

Precise clinical knowledge of liver anatomy is required to safely perform a hepatectomy, for both open and laparoscopic surgery. At the 19th meeting of the Japanese Research Society of Clinical Anatomy (JRSCA), we conducted special symposia on essential issues of liver surgery, such as the history of hepatic segmentation, the glissonean pedicle approach, application of 3-D imaging simulation and fluorescent imaging using indocyanine green solution, a variety of segmentectomies including caudate lobectomy, the associating liver partition and portal vein embolization for stage hepatectomy and harvesting liver grafts for living donor liver transplantation...

A 78-year-old man, who had presented with onset of ulcerative colitis at the age of 56 years and had been in remission for the past several years, attended our hospital with a diagnosis of obstructive jaundice. A hilar cholangiocarcinoma with right hepatic artery invasion was suspected on contrast enhanced CT. An endoscopic retrograde cholangiography indicated Bismuth type 2 stenosis. The stenotic bile duct brushings revealed no malignancy. Primary sclerosing cholangitis(PSC)and IgG4- related cholangitis were included in the differential diagnosis; however, a significant result could not be obtained in any other examinations...

BACKGROUND: Mucin-producing cholangiocarcinoma (MPCC) is an uncommon tumour that is clinically characterized by mucin-hypersecretion. Because the initial symptoms of MPCC may be attributed to the viscus mucobilia, the primary tumour mass may potentially be unrecognizable. We report an interesting case of curatively resected occult MPCC in situ. CASE PRESENTATION: A 70-year-old man was referred to our hospital with increased levels of biliary enzymes. Multidetector row computed tomography (MDCT) demonstrated a diffuse dilatation of the entire biliary system without evidence of tumour mass...

BACKGROUND: Caudate lobe is located in the deep dorsal area of the liver between the portal triad and the inferior vena cava (IVC). Torrential bleeding can occur from the IVC and short hepatic veins during dissection. Isolated total caudate lobe resection is still rare and technically demanding. We herein present a video on the technical aspect of laparoscopic total caudate lobectomy. METHOD: A 61-year-old woman was admitted for recurrent hepatocellular carcinoma detected on imaging...

OBJECTIVES: The purpose of this study is to identify the safety and feasibility of laparoscopic caudate lobectomy. BACKGROUND: Caudate lobectomy has been considered as technically difficult because of the deep location of the caudate lobe and its proximity to great vessels. Due to the technical difficulty, laparoscopic caudate lobectomy was not feasible in patients with malignancy in the caudate lobe. METHODS: Six consecutive patients with caudate hepatic malignancy received laparoscopic caudate lobectomy at Samsung Medical Center from September 2007 to May 2014...

A 2-year-old boy presented with pneumonia and an abdominal mass was noted incidentally. A right lobe hepatic mass classified as PRETEXT III and congenital absence of the portal vein with drainage of the superior mesenteric vein to the inferior vena cava (Abernethy malformation type I) were confirmed by computed tomography and angiography. After a clinical diagnosis of hepatoblastoma had been made, he was treated with 4 cycles of doxorubicin and cisplatin and hepatic arterial chemoembolization with doxorubicin, after which the tumor was classified as POSTEXT III...

The combination of hilar cholangiocarcinoma and anatomic variation constitutes a rare and complicated condition. Precise understanding of 3-dimensional position of tumor in the intrahepatic structure in such cases is important for operation planning and navigation. We report a case of a 61-year woman presenting with hilar cholangiocarcinoma. Anatomic variation and tumor location were well depicted on preoperative multidetector computed tomography (MDCT) combined with 3-dimensional reconstruction as the right posterior segmental duct drained to left hepatic duct...

Hilar cholangiocarcinoma (HCCA) is also known as cancer at the upper part of bile duct, perihilar cholangiocarcinoma or Klatskin tumor, etc.Bismuth-Corlette type Ⅲ hilar cholangiocarcinoma refers to tumor invading right hepatic duct (Ⅲa) or left hepatic duct (Ⅲb). While Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma refers to both left and right intrahepatic bile ducts being invaded. Under the premise of strictly grasping the indications of surgery, if preoperative management is conducted carefully, extended hepatic resection is a safe and feasible surgery to remove Bismuth-Corlette type Ⅲ and type Ⅳ hilar cholangiocarcinoma...

BACKGROUND: Lymph node dissection in Rouviere's sulcus (RS) is essential during left-sided hepatectomy and caudate lobectomy for hilar cholangiocarcinoma. However, the small segmental or subsegmental arteries (SA/SSA) are often encountered in RS and must be preserved to prevent critical complications, such as liver infarction or liver failure. The aim of this study is to elucidate the anatomy of SA/SSA around RS, which should be understood preoperatively. METHODS: Between January 2008 and April 2013 from a total of 124 consecutive patients with hilar cholangiocarcinoma, preoperative multidetector-row computed tomography (MDCT) images were obtained at our institution and evaluated...

BACKGROUND: Radical resection for hilar cholangiocarcinoma (HCa) is one of the most challenging abdominal procedures. Robotic-assisted approach is gaining popularity in hepatobiliary surgery but scarcely tried in the management of HCa. We herein report our initial experience of robotic radical resection for HCa. METHODS: Between May 2009 and October 2012, 10 patients underwent fully robotic-assisted radical resection for HCa in a single institute. The perioperative and long-term outcomes were analyzed and compared with a contemporaneous 32 patients undergoing traditional open surgery...

BACKGROUND: Isolated anatomic total caudate lobectomy is indicated in patients who have liver tumors limited to the caudate lobe. However, isolated caudate lobe resection is a challenging surgical procedure that required safe and reliable techniques. All portal and hepatic veins that connect this area originate from the first branch of the portal vein or vena cava; therefore, the operator must be cautious of the potential for massive bleeding. METHODS: The important points regarding the safety of our procedure include creating an optimal surgical view and preparing for accidental bleeding before parenchymal dissection...

Oxaliplatin is an effective chemotherapeutic agent for the treatment of colorectal cancer; however, it may cause liver injury, particularly sinusoidal obstruction syndrome (SOS). Although SOS does not usually present with focal lesions on radiological images, the present study describes the case of a 22-year-old woman with oxaliplatin-induced SOS mimicking metastatic colon cancer in the liver. An abdominal computed tomography revealed a novel 1 cm, low-density lesion in segment 1 of the liver following the administration of the fourth round of oxaliplatin-based adjuvant chemotherapy for stage III colon cancer...

BACKGROUND: A right-sided hepatectomy with total caudate lobectomy is indicated for colorectal-cancer liver metastases (CLM) and hepatocellular carcinomas (HCC) located in the caudate lobe with extension to the right lobe of the liver. Caudate-lobe resection (i.e. segmentectomy 1 according to the Brisbane terminology) is one of the most difficult types of hepatectomy to carry out radically and safely. The deep portion of hepatic transection around the caudate lobe, hepatic veins and inferior vena cava is a critical source of massive bleeding...

PURPOSE: Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) has increased the rate of liver resections in patients with marginal future liver remnant. We here describe a modified ALPPS procedure with splitting-off the central liver segments for staged mesohepatectomy in patients with advanced gall bladder cancer. METHODS: A double in situ split for ALPPS (DALPPS) is performed with splitting-off the central liver segments (segments 1, 4, 5, and 8)...

Perihilar cholangiocarcinoma presents at the biliary and vascular junction of the hepatic hilum with a tendency to extend longitudinally into segmental bile ducts. Most patients show metastatic or unresectable disease at time of presentation or surgical exploration. In patients eligible for surgical resection, challenges are to achieve negative bile duct margins, adequate liver remnant function, and adequate portal and arterial inflow to the liver remnant. Surgical treatment is characterized by high rates of postoperative morbidity and mortality...
