Patterns of serum alkaline phosphatase activity in unilateral hepatic duct obstruction: a clinical and experimental study

The levels of serum alkaline phosphatase (ALP) were measured in eight patients with bile duct obstruction limited to one lobe of the liver. Although an initial rise of enzyme concentration was documented in every patient, unrelieved biliary obstruction was associated with a gradual return of ALP to normal values. The return to normal levels coincided with the development of atrophy of that part of the liver deprived of its bile drainage. An animal model of experimental selective biliary obstruction supported a causative association between reduction of hepatocyte mass and a decrease in ALP activity. It appears that normal serum ALP levels can be expected with advanced obstructive biliary disease. Suspected lobar or segmental duct obstruction warrants investigation--even if liver function tests are normal.     

肝胆管外科入路的应用解剖

目的探讨在不同肝门解剖结构条件下，肝内及肝门胆管的暴露途径。方法选用成人肝脏标本３０例，沿肝十二指肠韧带向肝门及肝内解剖，观察肝内外胆管的行径特点及其毗邻关系。结果肝管汇合的常见方式有３型，本组左右肝管正常汇合型１８例、二级肝管直接汇合型和右侧胆管变异支异常汇合型分别为６例。肝管行出肝门的水平有较大差异。肝门区管道结构的相互毗邻关系及Ｇｌｉｓｏｎ束在肝内的行径相对恒定。结论在正常的肝门解剖结构条件下，通过解剖肝门的方法可以暴露肝总管及左右肝管，在解剖变异或需要暴露更高位胆管时，可以借助肝正中裂切开法或肝方叶切开法达到暴露目的。     

腹腔镜肝切除术治疗左肝内胆管结石的临床应用

目的 探讨腹腔镜肝切除术治疗左肝内胆管结石的技术与疗效。 方法 回顾性分析2011年1月至2016年12月完成67例腹腔镜肝切除术治疗左肝内胆管结石临床及随访资料。 结果 全部67例患者合并左半肝或左外叶肝萎缩,腔镜手术方式包括左外叶肝切除48例、左半肝切除19例。其他腹腔镜下联合术式包括：胆囊切除术52例、胆总管探查术43例、T管引流术39例,胆总管一期修补术4例。手术切口长度（4.67±1.26）cm。术后发生胆漏3例,均经引流观察后自愈;1例因术后腹腔大出血合并胆瘘再手术治愈;肝脓肿1例,膈下脓肿1例,均经穿刺引流治愈。 结论 腹腔镜肝切除术治疗左肝内胆管结石安全可靠,术中应尽量取净其他胆道残余结石并连续紧密缝合左肝管残端。如结石已被取净胆总管的探查和T管引流并非必需。     

Surgical treatment of choledochal cysts

Biliary cystic disease is uncommon in Asia and very rare in Europe and the Americas. Patients with biliary cysts may present as infants, children, or adults. When patients present as adults, they are more likely to have stones in the gallbladder, common duct, or intrahepatic ducts and to present with biliary colic, acute cholecystitis, cholangitis, or gallstone pancreatitis. With increasing age at presentation, the risks of intrahepatic strictures and stones, segmented hepatic atrophy/hypertrophy, secondary biliary cirrhosis, portal hypertension, and biliary malignancy all increase significantly. Factors to be considered when performing surgery on patients with biliary cystic disease include: (1) age, (2) presenting symptoms, (3) cyst type, (4) associated biliary stones, (5) prior biliary surgery, (6) intrahepatic strictures, (7) hepatic atrophy/hypertrophy, (8) biliary cirrhosis, (9) portal hypertension, and (10) associated biliary malignancy. In general, regardless of age, presenting symptoms, biliary stones, prior surgery or other secondary problems, surgery should include cholecystectomy and excision of extrahepatic cyst(s). With respect to the distal bile duct, the surgical principle should be excision of a portion of the intrapancreatic bile duct with care to not injure the pancreatic duct or a long common channel. Resection of the pancreatic head should be reserved for patients with an established malignancy. With respect to the intrahepatic ducts, surgery should be individualized depending on whether (1) both lobes are involved, (2) strictures and stones are present, (3) cirrhosis has developed, or (4) an associated malignancy is localized or metastatic. When the liver is not cirrhotic, hepatic parenchyma should be preserved even when strictures and stones are present. If cirrhosis is advanced, hepatic transplantation may be indicated, but this sequence of events is unusual. If a malignancy has developed, oncologic principles should be followed. Whenever possible, resection of a localized tumor including adjacent hepatic parenchyma and regional lymph nodes should be performed.     

Preoperative cholangiography of the caudate lobe: Surgical anatomy and staging for biliary carcinoma

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.     

Three-dimensional morphology of intrahepatic bile ducts in patients with intrahepatic gallstones

Eight livers surgically resected for intrahepatic gallstones were submitted to graphic reconstruction from serial histological sections to correlate the peculiar ductal changes with the pathogenetic aspects of this disease. Reconstruction was aided by a microcomputer system we have developed. Further, morphometric analysis was added to relate the obstruction of portal veins with parenchymal atrophy. Three-dimensionally, the ducts in these livers were strikingly transformed into a chain of ampullar dilatations interposed by either bending or strictures. Morphometrically, even a stenotic segment was wider than a corresponding normal one, showing that it was a relative stricture. The parenchymal lobule was atrophic or even completely destroyed due to the frequent thrombotic obstruction of portal veins about 0.5mm diameter. These 3-D morphology of intrahepatic bile ducts provided little evidence of congenital bile duct anomaly for the origin of intrahepatic gallstones. The basic ductal changes were dilations, alternated with "stenoses" that were more apparent than real. On the other hand, both the frequent obstruction of small portal veins and the lobular atrophy reflected a severely reduced portal blood flow. Not only the recurrent cholangitis that is apt to occur upon dilated ducts, but this functional incompetence of a stone-harboring, atrophic liver lobe strongly suggests a surgical indication for hepatic resection.     

高位胆管良性狭窄的原因和治疗

目的探讨高位胆管良性狭窄的原因和防治。方法回顾性总结分析高位胆管良性狭窄460例的病因和治疗方法。结果病因依次为肝胆管结石(383例)、高位胆管损伤(54例)、胆囊结石Mirizzi综合征(21例)、单纯良性狭窄(2例)。分别行肝叶或肝段切除；经肝剖开狭窄胆管，肝胆管或肝门胆管空肠吻合；肝门胆管狭窄切开整形后与空肠大口吻合；吻合口狭窄切开扩大吻合；肝门胆管狭窄切开整形后T管支撑等手术。效果满意，优良率为90．1％。结论高位胆管良性狭窄的主要原因是肝胆管结石(83．3％)和高位胆管损伤(11．7％)。肝叶或肝段切除，或联合肝内胆管或肝门胆管空肠大口吻合是治疗肝胆管结石并肝胆管狭窄的有效方法。高位胆管损伤初期修复后较易发生胆管或吻合口狭窄，再次修复以胆管空肠Roux-en-Y大口吻合术效果最好。强调重在预防，在行胆道手术时避免胆管损伤。     

Surgical treatment of congenital dilatation of the bile duct with special reference to late complications after total excisional operation

The surgical treatment of 100 cases with congenital dilatation of bile duct with special reference to late complications was analyzed. There were no deaths nor occurrences of malignancy. Among 91 patients who had undergone the standard operation, namely total excision of the dilated extrahepatic bile duct and reconstruction after Roux-en-Y hepaticojejunostomy, there were one early complication (pancreatic juice leakage) and five late complications (four intrahepatic gallstones and one liver abscess). The cause of intrahepatic gallstone formation after a total excisional operation was attributed to the remaining intrahepatic bile duct dilatation and the stenosis located between the intrahepatic bile duct dilatation and the common hepatic duct. Accordingly, these results support the total excisional procedure for this condition; however, with regard to the cases associated with cystic dilatation of intrahepatic bile ducts, completely free bile drainage from the dilated intrahepatic biliary system should be performed at the radical operation.     

Recurrent liver tumor with intrabiliary ductal growth after hepatectomy for metastatic rectal cancer: Case report

A case of recurrent tumor with intrabiliary ductal growth after hepatic resection for liver metastasis from rectal cancer is presented. The patient, a 55-year-old female, underwent subsegmentectomy of the anteroinferior and posteroinferior areas of the liver for metastatic liver cancer on August 29, 1988. Computed tomography in February 1990 showed dilatation of the intrahepatic bile duct in the right anterosuperior subsegment (B8), in which a filling defect was detected by cholangiography through a percutaneous transhepatic biliary drainage (PTBD) catheter. Percutaneous transhepatic cholangioscopy (PTCS) revealed a protruding lesion without tumor vessels. Cholangioscopic biopsy revealed dysplasia, but not adenocarcinoma. However, recurrent tumor originating in the resected margin of the remnant liver was suspected, and resection of the right lobe of the liver and partial resection of the duodenum were therefore performed. The resected specimen showed a tumor, 4 cm in diameter, in the previous resected margin, forming a protruding lesion with a rough surface (measuring 10×20 mm) in the B8 bile duct. This case suggested the possibility of cancer recurrence in the resected margin of the liver after hepatectomy for metastatic colorectal cancer, with intrabiliary ductal tumor growth showing segmental biliary dilatation.     

Hepatectomy for cholangiocarcinoma complicated with right umbilical portion: anomalous configuration of the intrahepatic biliary tree

The right umbilical portion (right-sided round ligament) has been discussed as an intrahepatic portal venous anomaly associated with "left-sided gallbladder" in several reports. We treated two patients with right umbilical portion (RUP) associated with cholangiocarcinoma. Left hepatectomies were performed, preserving the residual hepatic blood flow and biliary continuity. From our experience in these patients we propose the presence of anomalous configuration of the intrahepatic biliary tree in RUP, because both patients showed medial segmental bile ducts ramified from the right and left hepatic ducts. In general, although the medial segmental bile duct ramified from the left, we surmised that this abnormal bilateral drainage pattern may not be a rare phenomenon in RUP. Special attention may be required to focus on the anatomy of the portal tributaries and biliary ramifications in RUP. Received for publication on July 7, 1999; accepted on Nov. 11, 1999     

Preliminary study of the anatomy of the venous drainage of the intrahepatic and extrahepatic bile ducts and its relevance to the practice of hepatobiliary surgery

Background : Although there have been many studies of the arterial supply of the biliary system, attempts to study the corresponding venous drainage have been few and all have been incomplete. The purpose of the present investigation is to describe the anatomy of the venous drainage of both the intrahepatic and extrahepatic bile ducts and to determine its relevance to hepatobiliary surgery. Methods : The intrahepatic and extrahepatic venous drainage of the bile ducts was investigated in seven specimens by injecting a solution of 10% gelatin coloured with Alcian blue into the portal vein or the superior mesenteric vein to outline the venous drainage. The specimens were dissected under loop magnification and representative drawings were obtained. Results : The surface of the intrahepatic and extrahepatic bile ducts was covered by a fine venous plexus. On the surface of the supraduodenal common hepatic duct and common bile duct the venous plexus drained laterally into marginal veins, usually two in number and known as the 3 o’clock and 9 o’clock marginal veins. Inferiorly the marginal veins and the venous plexus communicated with the pancreaticoduodenal venous plexus, which in its turn drained into the posterosuperior pancreaticoduodenal vein, a branch of the superior mesenteric vein. Superiorly the marginal veins divided into a number of branches. Some branches followed the left and right hepatic ducts into the liver, communicating with the venous plexus and the adjacent branches of the portal vein. Other branches of variable size entered either segment IV or the caudate lobe or process via the hilar venous plexus. A most important finding was that even after dividing the bile duct and all communicating veins at the upper border of the duodenum, the venous plexus and the marginal veins filled normally to the level of transection. This occurred almost certainly by retrograde filling from above. Conclusion : The satisfactory results of end‐to‐end anastomosis in whole liver transplantation depends partly on the presence of adequate venous drainage. This has been amply demonstrated by the injection studies. This would indicate that the poor results of end‐to‐end repair of the bile duct after surgical trauma results from other factors such as poor technique, devascularization of the cut ends due to trauma, and carrying out the anastomosis under tension. After resection of the hilum for cholangiocarcinoma the venous drainage of the left and right hepatic ducts and their branches depends mainly on the communications between the venous plexus on the ducts and the adjacent branches of the portal vein, even at a lobular or sinusoidal level. The satisfactory results obtained after anastomosis of the left and right hepatic ducts or their branches to a Roux loop of jejunum attest to this. This applies also to the transplantation of segments II and III in paediatric patients from related adult donors and in patients receiving split liver transplants. Finally, the venous drainage at the bifurcation of the common hepatic duct has been shown to enter the caudate lobe and segment IV directly. This suggests that a hilar cholangiocarcinoma may metastasize to these segments, and perhaps partly explain the significantly better long‐term results when the caudate lobe and segment IV are resected en bloc with the cholangiocarcinoma as part of modern radical surgery for this condition.

Management of an epidermoid cyst of the intrahepatic ducts

Epidermoid cysts of the biliary tree have not previously been described. A baby boy presented with a prenatally diagnosed echolucent intrahepatic cyst. Postnatal radioisotope study of the liver demonstrated that the cyst communicated with the biliary tree. Follow-up ultrasound at 6 months demonstrated that the cyst was filled with echogenic material consistent with either blood or biliary debris. Due to the potential for obstruction and cholangitis, surgery was planned. The cyst was located at the confluence of the right and left hepatic ducts and involved all of the common hepatic duct. The entire cyst was resected except for the patch containing 3 duct orifices: the opening of both hepatic ducts as well as the orifice leading to the common bile duct. A Roux-en-Y cyst jejunostomy was created to allow drainage of both left and right hepatic ducts. The connection also provided access to the cyst remnant through the common duct for future endoscopic monitoring of potential malignant transformation.

Abstract：

Objective To evaluate biliary digital imaging technology in determining the type of the intrahepatic bile duct anatomy and the transection plane of the duct in right lobe living donor liver transplantation(LDLT). Methods Mobile digital subtraction angiography was performed to show the intrahepatic bile duct anatomy of 66 liver transplant donor candidates. Combined with metal markers, the bile duct transection plane was defined. Comparing with the actual results, the effect of digital imaging technology in determining the intrahepatic anatomical variations and transection plane of the duct in LDLT was evaluated. Results Intrahepatic bile duct anatomical variations were showed in all donors by using digital imaging technology. type Ⅰ (classical type) was identified in45 cases (68.2%), type Ⅱ (with triple confluence, the simultaneous emptying of the right anterior segmental duct, right posterior segmental duct and left hepatic duct into the common hepatic duct) in 7 cases ( 10.6% ), type Ⅲ (no right hepatic duct stem, right posterior segmental duct draining into common hepatic duct) in 13 cases ( 19. 7% ), type Ⅳ (no right hepatic duct stem, right posterior segmental duct draining into left hepatic duct) in 1 case (1.5%), and type Ⅴ (complex variation ) in no case (0%). As a result, cases of type Ⅰ form a single anastomosis. In type Ⅱ, four cases formed double anastomoses, three cases formed single anastomosis with or without ductoplasty. In type Ⅲ, two anastomoses were formed in 9 cases, single anastomosis in 4 cases with ductoplasty. The case of type Ⅳ had double anastomoses. In all cases right lobe liver were harvested.Conclusions Biliary digital subtraction image combined with metal markers accurately defines intrahepatic bile duct anatomy and the transection plane, helping to reduce number of bile duct anastomosis, and contributes to safe graft harvesting.     

腹腔镜下左半肝切除术

肝内胆管结石是指结石位于肝内胆管。这种疾病在西方不多见而易发于东亚地区,(肝内胆管中的)结石和(或)狭窄等因素使肝内胆管反复发生化脓性感染,不仅加重胆管的狭窄和阻塞,并加重肝实质的损害,导致肝纤维化,萎缩;感染急性发作时又易发生菌血症、感染性休克、胆源性肝脓肿、胆管溃疡致胆道出血,病变晚期则可发生胆汁性肝硬化、门脉高压症等一系列严重的后果。近年来,因为左半肝较容易操作的解剖位置使得腹腔镜下左半肝切除术在肝胆外科手术中很快得到关注,研究和临床经验表明左半肝切除术用于肝胆管结石症,兼具解除肝管梗阻(结石,尤其合并存在的肝胆管狭窄)和去除化脓性感染病灶的双重效果,有效地提高了肝胆管结石的远期治疗效果。     

Analysis of caudate lobe biliary anatomy and its implications in living donor liver transplantation – a single centre prospective study

Biliary complications are a significant cause of morbidity after living donor liver transplant (LDLT). Bile leak may occur from bile duct (anastomotic site in recipient and repaired bile duct stump in donor), cystic duct stump, cut surface pedicles or from divided caudate ducts. The first three sites are amenable to post‐operative endoscopic stenting as they are in continuation with biliary ductal system. However, leaks from divided isolated caudate ducts can be stubborn. To minimize caudate duct bile leaks, it is important to understand the anatomy of hilum with attention to the caudate lobe biliary drainage. This single‐centre prospective study of 500 consecutive LDLTs between December 2011 and December 2016 aims to define the biliary anatomy of the caudate lobe in liver donors based on intraoperative cholangiograms (IOCs) with special attention to crossover caudate ducts and to study their implications in LDLT. Caudate ducts were identified in 468 of the 500 IOCs. Incidence of left‐to‐right crossover drainage was 61.37% and right to left was 21.45%. Incidence of bile leak in donors was 0.8% and in recipients was 2.2%. Proper intraoperative identification and closure of divided isolated caudate ducts can prevent bile leak in donors as well as recipients.
