ABSTRACT
Biliary surgery has a long history. Since the Renaissance era, countless predece-ssors began to understand the biliary ducts, developed from cholecystectomy to extrahepatic bile duct exploration, and made significant progress. Academician Zhiqiang Huang firstly applied hepatectomy to the treatment of complex hepatolithiasis, and developed biliary surgery from extrahepatic bile duct to intrahepatic bile duct. The establishment and maturity of the "Precision biliary surgery technology system" marks the era of "segment" in biliary surgery. However, due to the many uncertainties of the concept and technology in the entire diagnosis and treatment process, biliary surgery is still one of the most complicated areas in abdominal surgery, and the prognosis is in urgent need of improvement. In the future, biliary surgery will make a breakthrough from the current hepatic segment to molecular level. Surgeons will cooperate with experts in various fields, make medical decisions based on big data and artificial intelligence, and perform more precise surgeries.
ABSTRACT
Objective:To investigate the effect of different blood glucose and BMI levels on the outcome of closed biliary surgery in diabetic patients.Methods:Clinical data of 424 diabetes admitted to Shanxi Provincial People’s Hospital for closed biliary tract surgery from Jan. 2018 to Jun. 2019 were retrospectively analyzed. According to the fasting blood glucose and BMI levels, the subjects were divided into hyperglycemia and non-hyperglycemia groups and obesity and non-obesity subgroups. The differences of clinical data among different groups were compared and analyzed. Multiple regression analysis was used to analyze the factors of postoperative infection, length and cost of hospitalization.Results:①Compared with the non-hyperglycemia group, the hyperglycemia group had higher BMI, serum creatinine, blood urea nitrogen, blood glucose monitoring rate, glycated hemoglobin detection rate, postoperative infection rate, ICU occupancy rate, length and cost of hospitalization, and lower albumin level, all P<0.05.②The age, fasting blood glucose, serum creatinine, low density lipoprotein, length and cost of hospitalization in the hyperglycemic obese subgroup were all lower than those in the non-obese subgroup, all P<0.05; and the serum creatinine in the obese subgroup was higher than those in the non-obese subgroup ( P<0.05) . ③Logistic analysis revealed that hyperglycemia was an independent risk factor for postoperative infection. For every 1mmol/L increase in fasting blood glucose, the risk of postoperative infection increased by 1.158 times, and albumin was a protective factor for postoperative infection. ④Multiple linear regression analysis showed that hyperglycemia and hypoalbumin were the important factors affecting the length of hospital stay and the increase of hospital cost, all P<0.05. Conclusions:Hyperglycemia is an independent risk factor for postoperative infection and a risk factor for longer hospital stay and higher costs. Obesity is not associated with postoperative infection or longer hospital stay, except for increased serum. Patients with diabetes undergoing closed biliary system surgery need to improve the detection rate of glycated hemoglobin and blood glucose monitoring rate, manage blood glucose reasonably, and control body weight appropriately.
ABSTRACT
Benign biliary strictures (BBSs) is a kind of difficult clinical problem in biliary surgery. Surgery and endoscopic treatment are common diagnostic and therapeutic methods. The rapid development of endoscopic technology challenges the traditional surgery. How to integrate surgery and endoscopic technology in an orderly manner and develop strengths and circumvent weaknesses requires a breakthrough in guiding ideas. The precision surgery, with the characteristics of certainty, predictability, controllability, standardization, individualization and systematization, has become an ideal choice for integrating surgery and endoscopic technology. Based on clinical practice, the authors discuss the endoscopic diagnosis and treatment strategy of BBSs from the perspective of precision surgery by implementing the core elements of precision surgery.
ABSTRACT
Precise hepatobiliary surgery technical system is a full-process and full-element surgical practice norm, which is based on the value of maximizing the benefit of patients, combining various technical means as its method, with safety, high efficiency and minimal trauma as the goal. Complicated hepatolithiasis is considered as benign disease but malignant prognosis because of its disease characteristics, such as difficult preoperative evaluation, difficult operation and difficult postoperative management. The precise hepatobiliary surgery technical system plays an important role in complicated hepatolithiasis. Based on the core of diseased biliary tree clearance, surgeons have improved the certainty of preoperative assessment and surgical operations through positioning, quantitative and structure technology. The author elaborates on the core, connotation of precise hepatobiliary surgery technical system and its application in complicated hepatolithiasis.
ABSTRACT
Perihilar biliary diseases have a wide spectrum of diseases including stones, inflammation, tumors, injuries and congenital malformations. Because of their characteristics such as anatomic variability, pathophysiological complexity, high operative difficulties, more postoperative complications and high operative risk, the perihilar biliary surgery is a high difficulty area in biliary surgery. For common clinical features ,common surgical methods and common technical difficulties of perihilar biliary diseases, the perihilar surgical technique system adequately evaluates hilar anatomy and its variations,liver function and volume of residual liver relying on threedimensional digital medical imaging technology, completely exposes hepatic hilum via combining anterograde and retrograde route from extra and intra-hepatic direction to hepatic hilum, then re-evaluates the relationship between the lesion and the hepatic artery and portal vein, and ultimately sets the surgical procedure . It is developed to improve the R0 resection rate, quality of cholangiojejunostomy, quality of vascular resection and reconstruction and safety of operation,eventually for the purpose of reducing postoperative complication rate and perioperative mortality and improving the prognosis. So surgeons should pay attention to the comprehensive system involving multiple disciplines in order to improve the effectiveness and safety in diagnosis and treatment of perihilar biliary diseases.
ABSTRACT

ABSTRACT
Due to the theoretical and technique limitation of traditional surgery,surgical treatment of complex intrahepatic biliary diseases was left for an unresolved difficult problem of the last century.Uncertainties of the anatomical,physiological,pathological changes and surgical techniques in the intrahepatic biliary tract contribute to this complexity.Through integrated application of modern scientific technology and traditional medicine methods and systematic optimization and innovation of biliary surgical theories and techniques,authors have developed a paradigm of precision biliary surgery which is characterized by high quantification,visualization and controllability.The establishment of the precise biliary surgical system solves the difficulty in surgeries for intrahepatic biliary diseases,puts forward the biliary surgery from extrahepatic ducts,hilar ducts to intrahepatic ducts,entering a new segment era of the biliary surgery marked by precision treatment of intrahepatic biliary diseases.
ABSTRACT
With inheritance of scientific spirit of Huang Zhiqiang,depending on the modern science and technology of evidence-based medicine methods,digital surgical technique,molecular imaging technique,minimally invasive technology,genomics and proteomics technology and Big Data analytics,giving full play to the characteristics of precision surgery,which include evidence-base,quantification,visualization and controllability,a new era of biliary surgery in China is inaugurated.
ABSTRACT
Bile duct has great attraction to surgeons due to its special anatomical location,unique biological features and origin of complicate diseases.Minimally invasive surgery,represented by laparoscopic cholecystectomy and Davinci robotic surgical system,has brought technic revolutions to traditional biliary surgery.In order to understand the prospect and regression of biliary surgery in the new era,we need to upgrade the knowledge of the biliary system,and systemically investigate the anatomy and development of bile duct.The study of biliary system should follow the path of extrahepatic system to hilar and then to the intrahepatic system,and the intrahepatic biliary disease should be emphasised in this new era.
ABSTRACT
En la actualidad, en la formación de los cirujanos en cirugía biliar se ha verticalizado el entrenamiento en colecistectomía laparoscópica, minimizando la formación en cirugía abierta, necesaria por la posibilidad de la conversión quirúrgica y por la presencia de casos complejos. El objetivo de este artículo es presentar una discusión científica sobre la importancia de la formación en cirugía biliar compleja, sobre la base de una situación clínica específica: una paciente con antecedentes de una cirugía compleja en el abdomen superior que consistió en la resección hepática y la reparación de la aorta abdominal, el duodeno y el estómago. La paciente presentó una litiasis biliar complicada, situación que obligó a la intervención abierta, con la cual se obtuvo un resultado satisfactorio. La colecistectomía videolaparoscópica es un procedimiento seguro y eficaz en las colecistopatías litiásicas y alitiásica, y la colecistectomía abierta o tradicional queda como alternativa de la primera, pero es indispensable un entrenamiento básico formativo en ella, no solo por una potencial conversión quirúrgica, sino por la posibilidad de encontrar situaciones como la aquí presentada.
At present times, the formation of surgeons in the field of biliary surgery has increased training in laparoscopic cholecystectomy and reduced training in open surgery which is necessary for the surgical conversion possibilities and the presence of complex cases. The objective of this article was to present a scientific discussion about the importance of the formation of specialists in complex biliary surgery, on the basis of a specific clinical case. This is the case of a woman with a history of complex upper abdomen surgery comprising liver resection and repair of the abdominal aorta, the duodenum and the stomach. The patient presented with complicated biliary lithiasis that forced the physicians to perform open biliary surgery; the result was satisfactory. Laparoscopic cholecystectomy is a safe and effective procedure in lithiasis and alithiasis cholecystopathy whereas open or traditional cholecystectomy remains as an alternative to the former. However, it is indispensable to provide basic formative training in open cholecystectomy, not only because of potential surgical conversion but because of likelihood of situations similar to the one presented here.

Objective To study the effect of MRCP for operation difficulty assessment before laparoscopic cholecystectomy. Methods 110 patients with gallbladder stone were randomly selected from March 2011 to July 2012 in our hospital,and all the patients were given LC operation after examined by MRCP. Regarded the average operation time 30 min as a criterion,when the operation time was no more than 30 min,the operation was considered as normal operation;when the operation time was more than 30 min, the operation was considered as op-eration of a certain degree of difficulty. Made a correlation analysis between LC operation difficulty and age,gender,location,volume of gall-bladder,angle of ductus cysticus, thickness of gallbladder wall, circumstances surrounding the cystic duct, length of ductus cysticus, and whether there were calculus in the cervical part of gallbladder. Results The difficulty level of LC operation is related to length of ductus cys-ticus and whether there were calculus in the cervical part of gallbladder,and there is no correlation with age,gender,location,volume of gall-bladder,angle of ductus cysticus,thickness of gallbladder wall,circumstances surrounding the cystic duct. Conclusion Routinely MRCP test in preoperative patients is of important significance to the prediction of LC operation difficulty.
ABSTRACT

ABSTRACT
The reoperation for biliary diseases is usually unplanned, and the major reasons leading to this situation include:(1) The initial operation was performed under emergency situation and radical procedure could not be carried out.(2) The surgical procedure was inadequate.( 3 ) The operator was unqualified for the operation. In order to avoid repeated operations,the following principles must be obeyed strictly.Firstly,once the initial operation was failed,the patients must be transferred to large medical center and the reoperation must be performed by hepatobiliary specialists.Secondly,the operator must realize that most of the patients were in poor condition because of the previous operation,and they needed careful evaluation of organ function and adequate supportive treatment before reoperation.Thirdly,various measures must be taken to avoid unplanned operation and ensure the successful implement of radical operation at a time:( 1 ) Operator must learn all the details of previous operation,which include operation procedure,findings during operation and postoperative complications.( 2 ) Cholangiogram of the whole biliary tree is important for surgical planning,ultrasonography,computed tomography (CT),endoscopic retrograde cholangiopancreatography,magnetic resonance cholangiopancreatography, percutaneous transhepatic cholangiography (PTC),or PTC-CT should be performed solely or comprehensively to determine the nature and location of lesions.For bile duct injury,additional examination including CT angiography,magnetic resonance angiography or digital subtraction angiography is necessary to ascertain the accompanied vessel injury.(3) Making individual surgical procedure according to patien's condition and distribution of lesions.

ABSTRACT
This article traced how western medicine and surgery were introduced into China, described where Chinese surgery stands currently at the international scene, and proposed future strategies as to how Chinese surgery can go internationally. Surgery, a major component of western medicine,was first introduced into China in the late 19th and early 20th centuries through the missionaries and the merchants of the East Indian Company. Surgical centers were soon established in the big cities along the coastal region, then spread inland along the Yellow River, the Yangtze River and the Pearl River. The establishment of general surgery centers soon led to the development of the subspecialty in hepatopancreatobiliary surgery because of high prevalence of hepatitis B related hepatocellular carcinoma, intrahepatic stones, portal hypertension caused by schistosomiasis and pancreatic disease. For historical reasons,Chinese surgery was cut off from the outside world in the 1960s.This led to the development of Chinese surgery along a different path from that taken internationally. With the opening up of China in the 1980s, and the recent economic developments,Chinese surgery needs to merge with surgery in the rest of the world. Suggested proposal for future strategies for Chinese surgery to go internationally include undergraduate medical reform, introduction of structured surgical training and examination for the whole country, life long continuing medical education for all surgeons, academic exchanges with internationally renowned centers, publication in international peer-review journals, active involvement in international surgical societies and conferences.
ABSTRACT
Objective To investigate the effects of intravenous fluid restriction on complications after biliary surgery.Methods The clinical data of 168 patients who received biliary surgery at the Nanjing General Hospital of Nanjing Military Command from October 2006 to March 2008 were prospectively analyzed.All patients were randomly divided into test group(85 patients received fluid restriction treatment)and control group(83 patients received conventional treatment)by the sealed envelope method.The difference in the fluid volume between the 2groups was observed.Differences in systemic complication rate,local complication rate,general complication rate,time to bowl movement,length of hospital stay and mortality between the 2 groups were compared.All data were analyzed using the chi-square test,t test,Fisher exact test,Results The median total volumes of fluid in test group and control group were 1450 ml and 2420 ml,respectively,with significant difference between the 2 groups (t=-5.067,P0.05).Conclusion Fluid restriction reduces the complication rate,shortens the length of hospital stay and accelerates recovery after biliary operation.
ABSTRACT
Background: Chile has a high incidence of cholelithiasis and associated complications, that usually require surgical treatment. Aim: Lo carry out an enquiry about biliary diseases and their surgical treatment in public and prívate surgical services in Chile. Material and Methods: An enquiry about liver and biliary diseases and their treatment was designed and sent by electronic mail to 35 surgical services. Results: Lhe enquiry was answeredby 17 services. A total of 9.505 cholecystectomies were reported. Between21 and 98 percent of the procedures were laparoscopic. Iatrogenic lesions of the biliary tree were reported in 0.3 percent of the procedures. Choledocolithiasis was found associated to cholelithiasis in 0 to 21 percent of procedures. However, the use of intraoperative cholangiography was incidental. Lhe incidence of gallbladder cancer in cholecystectomies for cholelithiasis fluctuated between 0.2 and 8.9 percent. Liver metastases derived from colorectal cancer were the most common liver tumor operated. Hydatidosis was more common in southern Chile. Pancreatic excision was almost exclusively performed in Metropolitan Santiago. Conclusions: This information will allow the establishment of information and collaboration channels among the surgical services throughout Chile.
Se trata de una encuesta realizada con el objeto de conocer la frecuencia e incidencia de las principales patologías y técnicas quirúrgicas de la esfera hepato-bilio-pancreática atendida en centros de salud públicos y privados del país durante el año 2007. La encuesta fue respondida por 17 instituciones nacionales. Entre los resultados resaltan el total de colecistectomías reportadas de 9.505, de las cuales entre un 21 y 98 por ciento son realizadas por vía laparoscópica. Lesiones iatrogénicas de vía biliar ocurrieron dentro de un rango de 0 a 1,5 por ciento, con una mediana de 0,3 por ciento. La frecuencia de coledocolitiasis asociada a la colelitiasis ocurrió entre un 0 a 21 por ciento, aunque el empleo de colangiografía intraoperatoria es en general de ocurrencia incidental. La incidencia de cáncer vesicular en colecistectomías por colelitiasis es claramente distinta según se trate de instituciones de centro-norte y sur del país, con incidencias que varían entre 0,2 y 8,9 por ciento. Las metástasis hepáticas operadas son principalmente de origen colorrectal, y son los tumores hepáticos más frecuentemente tratados. La hidatidosis hepática manifiesta en esta encuesta su conocida distribución geográfica, siendo más frecuentemente tratada en los centros del sur del país. La cirugía pancreática resectiva tiende a estar concentrada en las instituciones de la región metropolitana.
