The biliary branches of the caudate lobe (B1) join the right hepatic duct, the left hepatic duct, the confluence of these
ducts, and/or the right posterior segmental bile duct. Therefore, in the preoperative staging of biliary tract carcinoma it
is important to delineate the anatomy of B1 and the extent of cancer spread into B1. Tube cholangiography through percutaneous
transhepatic biliary drainage or selective cholangiography by percutaneous transhepatic cholangioscopy enables us to obtain
fine images of B1. We have developed cholangiography in the cephalad anterior oblique position to visualize B1 more clearly
and distinctly. Four separate types of biliary branches are identified in the caudate lobe: (1) A duct running from the cranial
portion of the right caudate lobe along the inferior vena cava to the hepatic hilus (B1r); (2) a duct from the cranial portion
of the left caudate lobe to the hepatic hilus (B1ls); (3) a duct from the left lateral part of the left caudate lobe to the
hepatic hilus (B1li); and (4) a duct from the caudate process to the hepatic hilus (B1c). The findings of the root of B1 in
resected patients with biliary tract carcinoma were classified into four groups: not stenotic, short segmental stenosis, long
segmental stenosis, and poorly imaged. A study of 64 branches of B1 in 42 resected patients with biliary tract cancer revealed
carcinoma invasion in or near the root of B1 in all patients with poorly imaged or long segmental stenosis of B1, and in 33%
of those with short segmental stenosis of B1. 相似文献

The purpose of this study is to clarify positional relationship between the bile duct of the caudate lobe and the bile duct of the hepatic hilum through endoscopic retrograde cholangiogram (ERC). Until December 1984 all 100 ERC that met the following three conditions were studied which at Yachio Hospital. 1. The first cholangiogram. 2. Without obstructive jaundice. 3. No existence of lesion at the hepatic hilum. Bile duct of the caudate lobe were classified into 4 separate types: 1) Ducts from the cranialis of the right caudate lobe which pass via the inferior vena cava to the hepatic hilum named Blr, were confirmed in 32. 2) Ducts from the cranialis of the left caudate lobe to the hepatic hilum named Bl l s, were confirmed in 19. 3) Ducts from the left lateral part of the left caudate lobe to the hepatic hilum named Bl l i were confirmed in 37. 4) Ducts from the caudate process to the hepatic hilum named Blc, were confirmed in 5. One or more of the above bile ducts were confirmed in 53 cases. All four of the above were confirmed in only 2 cases out of 53 cases. Three were confirmed in 7 out of 53 cases, two were confirmed in 20 cases out of 53 cases and one was confirmed in 24 out of 53 cases. Studies for the bile duct of the caudate lobe have been conducted anatomically, but there has been no research by clinical examination.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

A case of polypoid carcinoma of the left hepatic duct in 50-year-old male was reported. Extended left hepatic lobectomy with total caudate lobectomy and resection of the right hepatic duct were performed because the tumor involved the right hepatic duct and bile duct branches of caudate lobe, medial and lateral segment. Papillary growth of the tumor was diagnosed definitely by percutaneous transhepatic cholangioscopy (PTCS) and computed tomography. The tumor infiltrated the liver parenchyma of medial segment and compressed the middle hepatic vein. These findings were revealed by selective middle hepatic venography preoperatively. 相似文献

A case of gallbladder carcinoma in a 75-year-old woman with familial hyperbilirubinemia and preoperative hepatic dysfunction
is presented. Tube cholangiography through a percutaneous transhepatic biliary drainage (PTBD) catheter demonstrated a stricture
and the hepatic confluence without filling of the gallbladder and showed two bile duct branches arising from the left caudate
lobe. Cholangiography also disclosed that the left dorsal branch, which joined the right hepatic bile duct, was involved with
tumor, while the left ventral branch, which joined the left hepatic duct, was not. Extended right hepatic lobectomy with resection
of the dorsal portion of the left caudate lobe, preserving the ventral portion of the left caudate lobe, was performed. Postoperative
cholangiography showed that the ventral branch of the left caudate lobe bile duct was preserved. Precise preoperative anatomic
diagnosis of the biliary system in patients with hepatobiliary cancer allows successful subsegmental resection of the caudate
lobe.

From January 1976 through December 1988 we encountered ninety nine cases of intrahepatic stones. Eight of them were complicated with postoperative bile duct strictures which were formed on cholangiojejunostomy in 5 cases, cholangioduodenostomy, hepatic hilum and common hepatic duct in 1 case, respectively. Six cases of them are anastomotic strictures. The stones were mainly composed of bilirubin calcium. We guessed that the bile duct stricture resulted from cholangiojejunostomy without Roux-en-Y in 1 case and anastomotic insufficiency in 5 cases. Intrahepatic stones were removed by percutaneous transhepatic cholangioscopy (PTCS), and the treatment for the stricture was cholangiojejunostomy in 1 case and the dilatation by PTCS in 5 cases, including 3 endoprostheses by pig-tail silicone catheter and 2 internal-external biliary drainage. Two patients who did not undergo cholangioscopic dilatation died of sepsis due to cholangitis. Three of 5 patients who underwent endoscopic dilatation by PTCS could return to social life without recurrence of gallstones. In other two cases an endoprosthetic catheter was removed by PTCS because of dislodgement or obstruction of the catheter after confirming anastomotic strictures had improved. Authors recommended that PTCS should be applied for postoperative bile duct stricture complicated with intrahepatic stone. 相似文献

We report a 78-year-old man with a gallbladder carcinoma and biliobiliary fistula, diagnosed by percutaneous transhepatic
cholangioscopic biopsy through the fistula. The impacted stones in the common hepatic duct were crushed, and then selective
cholangiography under percutaneous transhepatic cholangioscopy (PTCS) revealed a biliobiliary fistula. Cholangioscopic biopsy
tissues taken from the gallbladder revealed adenocarcinoma, but biopsies taken from the fistula revealed no evidence of malignancy.
Further investigations indicated that the gallbladder carcinoma involved the duodenum and the distal common bile duct. A hepatopancreatoduodenectomy,
including both an extended right hepatic lobectomy with resection of the caudate lobe and a pancreatoduodenectomy, was performed.
Despite the patient's advanced age, he made an unremarkable postoperative recovery and was able to enjoy an active social
life for 8 months after the surgery. We discuss biliobiliary fistula associated with gallbladder carcinomas and the use of
hepatopancreatoduodenectomy for advanced biliary cancer in aged patients.

Curative resection of hepatocellular carcinoma with intrabile duct tumor growth mimicking hilar bile duct carcinoma 总被引:1,自引:0,他引:1

A 62-year-old Japanese male was admitted with obstructive jaundice and underwent percutaneous transhepatic cholangiodrainage
(PTCD). An initial diagnosis was made of hilar bile duct carcinoma, based on demonstrated irregular stenosis of the hilar
hepatic bile ducts without obvious tumor within the liver and negative alpha-fetoprotein (AFP). Enhanced computed tomography
(CT) showed an irregular low density area around the hepatic hilum and the umbilical portion of the portal vein, suggesting
carcinomatous invasion with blood flow disturbances. In contrast, intraoperative ultrasonography (US) raised the suspicion
of an ill-defined lesion in Couinaud's segment 2 (segment 2) and intrabile duct tumor formation. A radical extended left and
caudate lobectomy of the liver was successfully performed, with additional resection of extrahepatic bile duct and enbloc
resection of regional lymph nodes. Unexpectedly, histological analysis of the resected specimen showed the final diagnosis
to be hepatocellular carcinoma (HCC) of segment 2 with intrabile duct tumor growth. This case demonstrates that HCC with intrabile
duct tumor growth toward the heptic hilum can mimic hilar bile duct carcinoma, when the tumor itself is equivocal on preoperative
imaging and AFP is negative. In such cases, intraoperative US and guided biopsy may be of value for definitive diagnosis and
selection of the optimal procedure. 相似文献

OBJECTIVE: We present our experiences with infraportal bile duct of the caudate lobe (B1) and discuss surgical implications of this rare variation. SUMMARY BACKGROUND DATA: Although various authors have investigated biliary anatomy at the hepatic hilum, an infraportal B1 (joining the hepatic duct caudally to the transverse portion of the left portal vein) has not been reported. METHODS: Between January 1981 and December 2005, 334 patients underwent hepatectomy combined with caudate lobectomy for perihilar cholangiocarcinoma. Four of them (1.2%) had infraportal B1 and were investigated clinicoanatomically. RESULTS: All infraportal B1 were B1l, draining Spiegel's lobe; no infraportal B1r (draining the paracaval portion) or B1c ducts (draining the caudate process) were found. The infraportal B1l joined the common hepatic duct or the left hepatic duct. Three patients underwent right trisectionectomy with caudate lobectomy; for one, in whom preoperative diagnosis was possible, combined portal vein resection and reconstruction were performed before caudate lobectomy to resect the caudate lobe en bloc without division of infraportal B1. For the other 2 patients, the infraportal B1 was divided to preserve the portal vein, and then the caudate lobe was resected en bloc. The fourth patient underwent right hepatectomy with right caudate lobectomy; the cut end of the infraportal B1 showed no cancer by frozen section, so the bile duct was ligated and divided to preserve the left caudate lobe. CONCLUSION: Infraportal B1 can cause difficulties in performing right-sided hepatectomy with caudate lobectomy or harvesting the left side of the liver with the left caudate lobe for transplantation. Hepatobiliary and transplant surgeons should carefully evaluate biliary anatomy at the hepatic hilum, keeping this variation in mind. 相似文献

We report a case of small pancreatic carcinoma misdiagnosed as superficially spreading cholangiocarcinoma using percutaneous
transhepatic cholangioscopy (PTCS). The patient was a 72-year-old man admitted to a local hospital with obstructive jaundice.
The patient underwent percutaneous transhepatic biliary drainage and PTCS. He was referred to our hospital with a diagnosis
of superficially spreading cholangiocarcinoma. Cholangiography revealed a stenosis of the common bile duct, and also revealed
some irregularities from the common hepatic duct to the left hepatic duct, suggesting a superficial spread of cancer. No pancreatic
tumor was identified by endoscopic retrograde pancreatography or by enhanced computed tomography. Cholangioscopy disclosed
an elevated tumor with torsional vessels and granular mucosal lesions, which were extended to the left hepatic duct. Repeated
cholangioscopic biopsies of the bile duct mucosa revealed adenocarcinoma. The patient was diagnosed with superficially spreading
cholangiocarcinoma extending to the left hepatic duct and the right anterior hepatic duct. Left trisectionectomy combined
with pancreatoduodenectomy was performed. The cut surface of the resected specimen showed a pancreatic head tumor that was
8 mm in diameter. Histological findings of the resected specimen revealed adenocarcinoma arising from the pancreatic head
with invasion in the common bile duct. Additionally, extensive inflammatory granulation tissue was observed along the surface
of the bile duct, without any evidence of carcinoma. This case implies to us that the results of PTCS, even after repeated
biopsies, should be interpreted with great caution. 相似文献

Abstract Objective To evaluate the safety, efficiency, indications and procedure of percutaneous transhepatic cholangioscopy (PTCS), using a one-stage percutaneous tract dilation technique, in patients with intrahepatic and/or common bile duct stones. Methods The medical records of 35 cases of intrahepatic and/or common bile duct stones treated by PTCS, using a one-stage tract dilation technique, from January, 2015 to April, 2017 in the Second Affiliated Hospital of Zhejiang University School of Medicine were studied retrospectively. All the patients were treated with lithotripsy and basket stone removal through PTCS using one-stage percutaneous tract dilation technique after percutaneous transhepatic cholangial drainage (PTCD). The perioperative morbitity, stone clearance rate, and stone recurrence rate were analyzed. Results The intrahepatic biliary duct and common bile duct were successfully accessed in all 35 cases using ultrasound-guided one-stage percutaneous tract dilation PTCS technique. The stones were completely removed (level A) in 65.7% (23/35) of the cases including 18 cases of intrahepatic stones and 5 cases of common bile duct stones. The stones were almost cleared (level B) in 22.9% (8/35) of intrahepatic stones cases. Stone clearance was achieved in 31 (88.6%) cases (level A and B). One case suffered PTCD site bleeding and one case had percutaneous transhepatic tract rupture during the secondary stone removal procedure. There were no other serious procedure-related complications such as life-threatened bleeding, bile leak and conversion to laparotomy. With follow-up of 1-28 months, 6 (26.1%) of 23 cases of level-A stones clearance had recurrent intrahepatic stones and cholangitis. Conclusion PTCS using one-stage dilation of the tract, is an effective, safe and alternative minimal invasive method forintrahepatic and/or common bile duct stones when surgery or peroral approach is not indicated. 相似文献

Hilar bile duct carcinoma has a poor prognosis, but this has been improved in recent years by an aggressive surgical approach.
We treated a 73-year-old woman who had obstructive jaundice due to bile duct carcinoma at the hepatic hilum. The jaundice
decreased after percutaneous transhepatic biliary drainage. The tumor was resected with the left and caudate lobe of the liver
and a part of portal vein. The right hepatic artery was located behind the common hepatic duct, and was suspected to be invaded
by the tumor. We dissected the tumor from the arterial wall without carrying out combined resection of the hepatic artery.
On the 6th postoperative day, the hepatic artery ruptured and the patient suffered hypovolemic shock. Resection of the hepatic
artery and reconstruction were done, but the patient died 2 days later. Histological examination of the resected artery showed
that the tumor had been curatively removed by dissection and that no tumor remained at the arterial wall. The rupture of the
right hepatic artery was thought to have been caused by damage to the wall during the dissection procedure. 相似文献

A case of superficially-spreading carcinoma of the hepatic hilus is presented. Percutaneous transhepatic biliary drainage was performed to alleviate jaundice and to evaluate the biliary system. A nodular tumor originating in the upper part of the common hepatic duct was found to be invading the confluence of the right and left hepatic ducts. Extensive superficial spread was observed in the proximal portion of the right anterior superior, right anterior inferior, right posterior superior, right posterior inferior, and caudate bile duct branches. Preoperative surgical planning was carried out on the basis of an evaluation of the findings of ultrasonography, computed tomography, percutaneous transhepatic cholangiography, and percutaneous transhepatic cholangioscopy. Absolute curative surgery, which included right hepatic lobectomy with total caudate lobectomy and bile duct resection, was performed. Bilioenteric continuity was reestablished with a Roux-en-Y jejunal loop. The histological diagnosis was well-differentiated tubular adenocarcinoma of the common hepatic duct. Postoperative recovery was very good; the patient has now enjoyed a good active social life for the past 4 years and 10 months, with no signs of recurrence. In this case report, we discuss the precise preoperative diagnosis and rational surgical treatment for carcinoma of the hepatic hilus with superficial spread. 相似文献

A case of cholangiocellular carcinoma, involving the hepatic hilus, radically resected by central hepatic bisegmentectomy
with en bloc resection of the caudate lobe and extrahepatic bile duct is presented. Preoperative surgical planning was carried
out on the basis of an evaluation of the findings of ultrasonography, computed tomography, angiography, percutaneous transhepatic
portography, and tube cholangiography. The operation lasted for 16 h and 15 min, with 5700 g blood loss. Postoperative recovery
was very good and the patient has now been well for 26 months after surgery. Although the surgical technique of central hepatic
bisegmentectomy with en bloc resection of the caudate lobe and extrahepatic bile duct is very difficult, this procedure should
be indicated for selected cases of cholangiocellular carcinoma involving the hepatic hilus. 相似文献

We present herein the case of a pyogenic liver abscess developing from hepatic ischemia caused by resection of the right hepatic artery when a left hemihepatectomy with caudate lobectomy and extrahepatic bile duct resection was performed for cholangiocellular carcinoma. Postoperative cholangiography revealed communication between the abscess cavity and the intrahepatic bile duct. The liver abscess was successfully treated by percutaneous transhepatic drainage. Thus, breakdown of the intrahepatic bile duct due to ischemia may play an important role in the development of a pyogenic liver abscess following hepatic arterial occlusion. 相似文献

Accurate knowledge of partial anatomy is essential in hepatic surgery but is difficult to acquire. We describe the potential
impact of a new technique for constructing three-dimensional virtual images of the portal vein, hepatic artery, and bile ducts
and present a representative case. An 80-year-old man was suspected of having papillary cholangiocarcinoma arising in S8 of
the liver and extending to the hepatic hilum intraluminaly. Right hemihepatectomy with bile duct resection was planned. However,
it was uncertain whether duct-to-duct biliary reconstruction would be possible based on the appearance of the confluence of
the right and left hepatic ducts on cholangiogram and conventional computed tomograph. Virtual three-dimensional images of
the liver were constructed and revealed vascular and biliary anatomy. They showed that the upper margin of bile duct excision
would be 19 mm from the umbilical point of the left portal vein, and that the site of the left branch of the caudate lobe
bile duct could be preserved. Based on this information, we performed a sphincter-preserving biliary operation safely without
complications. Planning complex biliary surgery may be improved by the use of virtual three-dimensional images of the liver.
This approach is especially useful in candidates for postoperative regional chemotherapy. 相似文献

Extended liver resection for hilar cholangiocarcinoma 总被引:5,自引:0,他引:5

Liver resection for hilar cholangiocarcinoma should be designed for individual patients, based on both precise diagnosis of cancer extent and accurate evaluation of hepatic functional reserve. Therefore we have developed various types of hepatic segmentectomy. Combined caudate lobectomy is essential in every patient with separated hepatic confluence. So-called extensive hepatectomy, resection of 50% or more of the hepatic mass, includes right lobectomy and right or left trisegmentectomy. Right lobectomy with caudate lobectomy is indicated when the progression of cancer is predominant in the right anterior and posterior segmental bile ducts. The plane of liver transection is along the Cantlie line, and the left hepatic duct is divided just at the right side of the umbilical portion of the left portal vein. Right trisegmentectomy with caudate lobectomy is performed in carcinoma which involves the right hepatic ducts in continuity with the left medial segmental bile duct. The umbilical portion of the left portal vein is freed from the umbilical plate by dividing the small portal branches arising from the cranial side of the umbilical portion. Then the left lateral segmental bile ducts are exposed and divided at the left side of the umbilical portion of the left portal vein. Left trisegmentectomy with caudate lobectomy is suitable for carcinoma which involves the left intrahepatic bile duct in continuity with the right anterior segmental bile duct. Liver transection is advanced along the right portal fissure. The right posterior segmental bile duct is usually divided distal to the confluence of the inferior and superior branches. 相似文献

Bile duct carcinoma, which produces clinically recognizable mucus, was defined as "mucus producing bile duct carcinoma", and clinicopathological study was carried out in 7 cases of bile duct carcinoma suitable for the definition. All the tumors arose from the intrahepatic bile duct. There were no tumors arising from the extrahepatic bile duct. Superficially spreading mucosal infiltration of carcinoma was recognized in 6 cases out of 7, and accordingly distinct cholangiography after draining mucus through percutaneous transhepatic cholangio-drainage (PTCD) and percutaneous transhepatic cholangioscopy (PTCS) were indispensable for accurate diagnosis of the extent of carcinoma. The prognosis of patients with mucus producing bile duct carcinoma were almost satisfactory if rational operation had been performed according to accurate diagnosis. On the other hand, since mucus producing bile duct carcinoma frequently has a cystic lesion, the relation to biliary cystadenocarcinoma may become a subject of question. We advocate that biliary cystadenocarcinoma should be included in mucus producing bile duct carcinoma since biliary cystadenocarcinoma originally arises from the intrahepatic bile duct and very rarely from the extrahepatic bile duct. But now the concept of biliary cystadenocarcinoma is equivocal and further investigations will be requested. 相似文献

Exposure of the left hepatic duct through the hilum or in the umbilical of the liver: anatomic limitations 总被引:2,自引:0,他引:2
C Couinaud 《Surgery》1989,105(1):21-27
Anastomosis to the left hepatic duct approached by dissecting the hilar plate is the most reliable method of drainage of the left side of the liver in that longitudinal incision of the left hepatic duct allows a long cholangiojejunostomy. However, the anatomy is not satisfactory in 30% of cases for adequate drainage of the left side of the liver. To further clarify this surgically important area, 107 vasculobiliary casts were reviewed with regard to the anatomy and relationship between the left biliary ductal and left portal venous systems. In cases in which anatomy is unfavorable for adequate drainage by anastomosis to the left hepatic duct in the hilum, several options are available. The anterior portion of the main portal fissure may be opened to gain wide access to the superior aspect of the biliary plate and reach a posterior duct that is more suitable for anastomosis. An anastomosis to an anterior duct may also be possible with this approach. If left portal ducts are inaccessible by division of the main portal fissure because of a retroportal location, then an anastomosis in the anterior portion of the umbilical fissure may give adequate drainage. Therefore a cholangiogram is imperative before any anastomosis in the hilum or the anterior portion of the umbilical fissure. 相似文献
