The sphincter of Oddi:from incision to repair
Ceng JianPing, Dong JiaHong
2017, 33(2): 209-212. DOI: 10.3969/j.issn.1001-5256.2017.02.001
Abstract:
The sphincter of Oddi is a valve that controls the biliopancreatic duct and plays an irreplaceable role in maintaining normal physiological functions of the biliopancreatic duct.However,sphincteroplasty and sphincterotomy may cause varying degrees of damage to the function of the sphincter of Oddi,which may further result in postoperative reflux of duodenal fluids and bacterial contamination in bile and increase the risks of recurrent common bile duct stones,reflux cholangitis,and even cholangiocarcinoma.Therefore,clinical physicians should protect the structure and function of the sphincter of Oddi.Based on our experience,under the premise that the extrahepatic bile duct can be preserved,patients with iatrogenic injury of the sphincter of Oddi can be treated with transduodenal sphincteroplasty to restore the structural integrity of the sphincter of Oddi and reduce biliopancreatic duct complications secondary to loss of function.

Diagnosis and surgical treatment of xanthogranulomatous cholecystitis
Li ZhenLi, Yang Tian
2017, 33(2): 247-252. DOI: 10.3969/j.issn.1001-5256.2017.02.007
Abstract:
Xanthogranulomatous cholecystitis( XGC) is a rare type of chronic cholecystitis characterized by severe proliferative fibrosis with infiltration of macrophages and foamy cells in the gallbladder wall.Since XGC and gallbladder carcinoma have similar clinical manifestations and radiological features,XGC is often misdiagnosed as gallbladder carcinoma in clinical practice,which leads to unnecessary extensive surgical resection and has an adverse effect on patients.At present,the preoperative diagnosis of XGC is still based on imaging results( ultrasound,computed tomography,and magnetic resonance imaging),and a definite diagnosis of this disease relies on intraoperative frozen biopsy or postoperative pathological examination.Meanwhile,XGC should be differentiated from gallbladder adenomyomatosis,gallbladder carcinoma,and gallbladder actinomycosis.Laparotomy or laparoscopic cholecystectomy is the major method for the treatment of XGC,but laparoscopic cholecystectomy is associated with a longer time of operation,more complications,and a higher rate of conversion to laparotomy.Therefore,surgeons are facing difficulties in preoperative diagnosis and intraoperative decision- making process of XGC.
Improvement of minimally invasive therapies and techniques for intra- and extrahepatic bile duct stones
Tian Yu, Wu ShuoDong
2017, 33(2): 253-255. DOI: 10.3969/j.issn.1001-5256.2017.02.008
Abstract:
This article introduces the explorations in improving minimally invasive therapies and techniques for intra- and extrahepatic bile duct stones in this center,including laparoscopic choledocholithotomy without the placement of T tube,laparoscopic partial hepatectomy for the treatment of intrahepatic bile duct stones using an anastomosis stapler for liver partition,and modification of percutaneous transhepatic cholangioscopy.The improved therapies and techniques above have achieved good clinical effects,and a scientific judgment of their clinical effects still depends on a large number of cases and randomized controlled clinical trials.
Related issues in repair of bile duct injury and traumatic biliary stricture
Wang ShuGuang
2017, 33(2): 256-259. DOI: 10.3969/j.issn.1001-5256.2017.02.009
Abstract:
Inappropriate treatment of bile duct injury and traumatic biliary stricture may cause serious consequences such as recurrent cholangitis,formation of hepatolithiasis,and biliary cirrhosis.This article elaborates on the influencing factors for the effect of the repair of bile duct injury and traumatic biliary stricture,repair principles,timing of repair or reconstruction,and related methods and techniques.It is pointed out that if there is no significant local infection and the bile duct wall defect is < 2 cm,end- to- end anastomosis should be used for repair;if the bile duct wall defect is > 2 cm,Roux- en- Y hepaticojejunostomy should be used for reconstruction.If the upper wall of the bile duct had a large defect and the lower wall has an integral structure,pedicled umbilical vein graft,pedicled jejunal wall seromuscular flap,or gastric wall seromuscular flap should be used for repair.The patients with severe congestion and edema at the site of injury should be treated with sufficient external drainage of the injured bile duct and then selective repair or reconstruction.Patients with hepatic duct stenosis in the liver lobe or hepatic segments and liver tissue atrophy can be treated with hepalobectomy or segmental hepatectomy.The key to successful repair is exposure and removal of high hilar bile duct stricture,while segmental hepatectomy of the Ⅳb segment can fully expose the left and right hepatic pedicles and help with the incision of the left and right hepatic ducts and secondary hepatic ducts,and therefore,it is a good method for exposing high bile duct stricture.
Correct timing of bile duct injury repair
Wang Jian, Xu SunWang
2017, 33(2): 260-262. DOI: 10.3969/j.issn.1001-5256.2017.02.010
Abstract:
Surgical operation is the most important method for the treatment of iatrogenic bile duct injury,and correct selection of the timing of surgical repair is a prerequisite for successful injury repair.This article elaborates on the timing of immediate repair of bile duct injury found during surgery and the timing of delayed repair of bile duct injury found after surgery and summarizes the timing and methods for delayed repair based on the location and manifestations of injuries( such as biliary obstruction,bile leakage,and injury in the choledocho-pancreatico- duodenal junction).It is pointed out that the pathological state of injury is the critical factor for deciding surgical timing.The overall tendency of the timing of repair is early repair,and delayed repair should be performed as early as possible within 2- 4 weeks after effective control of inflammation.
Surgical treatment of congenital bile duct dilatation with involvement of the intrahepatic bile duct:advances,difficulties,and controversy
Yang ShiZhong, Xiang CanHong
2017, 33(2): 263-267. DOI: 10.3969/j.issn.1001-5256.2017.02.011
Abstract:
Congenital bile duct dilatation may occur in any part of the biliary tree,and the diagnosis and treatment of lesions involving the intrahepatic bile duct is the most challenging issue.Surgical operation plays a dominant role in the management of congenital bile duct dilatation,with the purposes of relieving symptoms and preventing disease progression and malignant transformation.Surgical principles are radical resection of lesions and reconstruction of unobstructed bile drainage.Hepatectomy is the main surgical procedure for congenital bile duct dilatation with involvement of the intrahepatic bile duct,and liver transplantation can be used for diffuse lesions.Therefore,we believe that hepatectomy and early intervention will maximize patients' benefits.
Diagnosis and treatment of ampullary tumors
Yin Tao, Zhou YingKe, Wu HeShui
2017, 33(2): 268-271. DOI: 10.3969/j.issn.1001-5256.2017.02.012
Abstract:
Ampullary tumors mainly manifest as obstructive jaundice and ampullary mass in clinical practice and are difficult to be identified in early stage due to a complex structure of the anatomical site,a deep location,and hidden symptoms.Sometimes a qualitative diagnosis cannot be made.Based on the experience in the treatment of ampullary tumors for many years in our center,this article summarizes the features of ampullary tumors from the aspects of clinical manifestations,diagnosis,treatment,and prognosis,especially the issues regarding imaging evaluation of ampullary tumors,selection of surgical procedure,and prognosis.An early diagnosis is the key to the treatment of ampullary tumors,and early identification and treatment of lesions have great impacts on patients' prognosis.Accurate preoperative imaging evaluation,a professional diagnosis and treatment team,accurate preoperative and intraoperative pathological analysis,and implementation of reasonable therapeutic strategy are the key to patients' recovery.

Yu Tong, Zhai XiaoFeng, Liu Qun, Meng YongBin, Lu JianYing, Chen Zhe
2017, 33(2): 281-285. DOI: 10.3969/j.issn.1001-5256.2017.02.015
Abstract:
Objective To investigate the clinical effect and safety of hepatic arterial infusion of cinobufotalin injection combined with lipiodol chemoembolization( TACE) in the treatment of Barcelona Clinic Liver Cancer( BCLC) stage C primary liver cancer.Methods A retrospective analysis was performed for the clinical data of 82 patients with BCLC stage C primary liver cancer who were admitted to Department of TCM Oncology in Changhai Hospital from December 2010 to October 2014.According to intraoperative medication,the patients were divided into two groups.The 40 patients in the cinobufotalin group were treated with hepatic arterial infusion with cinobufotalin combined with lipiodol embolism,and the 42 patients in the control group underwent TACE with epirubicin.The objective response rate,time to progression,median survival time,and acute adverse events were compared between the two groups after a single treatment.The t- test was used for comparison of continuous data between groups,the chi- square test was used for comparison of categorical data between groups,and the Kaplan- Meier method was used for the analysis of cumulative survival rate.Results At 1.5 months after surgery,the cinobufotalin group had a significantly higher objective response rate than the control group( 27.5% vs 9.52%,χ~2= 4.429,P = 0.035).The time to progression was 2.4 months( 95% CI:1.978- 2.822) in the cinobufotalin group and 3.0 months( 95% CI:2.260- 3.740) in the control group,and there was no significant difference between the two groups( P = 0.344).The median survival time was 6.6 months( 95% CI:4.131-9.069) in the cinobufotalin group and 10.3 months( 95% CI:0.089- 20.511) in the control group,and there was no significant difference between the two groups( P = 0.132).At 5 days after surgery,the cinobufotalin group had significantly lower incidence rates of abnormal alanine aminotransferase level,white blood cell count,and platelet count,as well as adverse events including hepatalgia,abdominal distension,and nausea / vomiting than the control group( χ~2= 6.193,5.311,6.096,5.909,4.761,and 4.173,all P < 0.05).Conclusion As for patients with BCLC stage C primary liver cancer,hepatic arterial infusion of cinobufotalin injection combined with lipiodol chemoembolization has a better short- term therapeutic effect,milder adverse effects,and a similar long- term therapeutic effect compared with TACE with conventional chemotherapeutic agents.

Huang Jie, Ren ShiPu, Yang LiWen
2017, 33(2): 286-288. DOI: 10.3969/j.issn.1001-5256.2017.02.016
Abstract:
Objective To investigate the clinical effect of ultrasound- guided percutaneous transhepatic gallbladder drainage( PTGBD) in the treatment of acute cholecystitis.Methods A retrospective analysis was performed for the clinical data of 81 patients with acute cholecystitis who underwent ultrasound- guided PTGBD in General Hospital of Lanzhou Petrochemical Company from March 2013 to February 2016.The changes in related parameters after the placement of drainage tube were analyzed.The t- test was used for comparison of continuous data between groups.Results All the 81 patients underwent a successful one- time puncture.After the surgery,1 patient experienced tube dislodgement and 2 experienced obstructed bile drainage,while no patient experienced serious complications such as bleeding,bile leakage,and hemopneumothorax.Within 12 hours after surgery,there was a significant improvement in pain in the right upper quadrant and significant reductions in the major axis and radial width of the gallbladder( t = 13.28 and 9.54,P = 0.023 and 0.041),as well as significant reductions in white blood cell count and neutrophil count( t = 8.70 and 8.03,P = 0.028 and 0.034).Of all patients,38 achieved symptom remission after the placement of drainage tube and refused selective surgical treatment,and 43 underwent cholecystectomy within 3 months after surgery.Conclusion PTGBD is simple,convenient,visible,and safe and can effectively reduce patients' pain,increase the success rate of the treatment of acute cholecystitis,improve patients' clinical outcomes,and reduce the incidence of complications.It also provides the conditions of selective surgery for critically ill patients with acute cholecystitis,and therefore,it holds promise for clinical application.

2017, 33(2): 289-292. DOI: 10.3969/j.issn.1001-5256.2017.02.017
Abstract:
Objective To investigate the clinical effect of laparoscopic biliary reoperation in the treatment of elderly patients with extrahepatic bile duct stones.Methods A retrospective analysis was performed for the clinical data of 86 elderly patients with extrahepatic bile duct stones who were admitted to The First People's Hospital of Zaoyang from January 2013 to June 2015 and underwent laparoscopic biliary reoperation.The surgical conditions and follow- up results were compared between groups.The t- test was used for comparison of continuous data between groups,the chi- square test was used for comparison of categorical data between groups.Results All the patients underwent the surgery successfully and no patient died during the perioperative period.The postoperative stone clearance rate was 100%.There was no significant difference in the surgical procedure( primary suture / T- tube drainage) between the two groups( P > 0.05).Compared with the first operation group,the reoperation group had a higher rate of conversion to laparotomy,a longer length of hospital stay,higher intraoperative stone clearance rate and incidence rates of intraoperative and postoperative complications,and a significantly longer time of operation( t = 2.126,P = 0.036).In the first operation group,one patient experienced intraoperative cystic artery injury and was given ligation for hemostasis;in the reoperation group,2 patients experienced gastrointestinal serosal injury and were treated with embedding of the seromuscular layer.In the first operation group,1 patient each experienced bile leakage,pulmonary infection,and urinary system infection after surgery and were all cured after conservative treatment;in the reoperation group,1 patient experienced bile leakage and 2 experienced pulmonary infection,and all the patients were cured after conservative treatment.The overall follow- up rate was 94.19%( 50 /54) in the first operation group and 96.88%( 31 /32) in the reoperation group.The imaging examination showed no complications such as biliary stricture,residual bile duct stones,and recurrence of stones.Conclusion Laparoscopic biliary reoperation is safe and effective in the treatment of elderly patients with extrahepatic bile duct stones,but there are a certain rate of conversion to laparotomy and incidence rates of complications.The operation techniques should be improved to avoid intraoperative injury,surgical indications should be strictly followed,and perioperative management should be optimized.

Abstract:
Objective To investigate the risk factors for short- term residual common bile duct stones after laparoscopic cholecystectomy( LC),and to provide a reference for clinical prevention and treatment.Methods A total of 18 patients with short- term residual common bile duct stones after LC who were admitted to The First Affiliated Hospital of Nanyang Medical College from January 2014 to January 2016 were enrolled as observation group,and 320 patients without short- term residual common bile duct stones after LC who were admitted during the same period of time were enrolled as control group.The two groups were compared in terms of acute pancreatitis,alanine aminotransferase( ALT),aspartate aminotransferase( AST),emergency surgery,results of preoperative magnetic resonance cholangiopancreatography( MRCP),direct bilirubin( DBil),the gallbladder full of stones,number of gallstones,minimum stone diameter,gallbladder volume,cystic duct diameter,cystic duct length,and sand- like stones.The independent- samples t test was used for comparison of continuous data between groups,the chi- square test was used for comparison of categorical data between groups,and a logistic multivariate regression analysis was performed for variables with statistical significance.Results The univariate analysis showed that acute pancreatitis,emergency surgery,sand- like stones,retrograde cholecystectomy,preoperative MRCP,number of gallstones,minimum stone diameter,gallbladder volume,cystic duct diameter,and common bile duct diameter were associated with short- term residual common bile duct stones after LC( χ~2=9.801,16.217,5.802,9.865,and 5.145,t = 18.314,6.077,7.687,15.678,and 5.512,all P < 0.05).The multivariate logistic regression analysis showed that acute pancreatitis,retrograde cholecystectomy,common bile duct diameter,and cystic duct diameter were independent risk factors for short- term residual common bile duct stones after LC,while preoperative MRCP was a protective factor.Conclusion Active intervention for risk factors for short- term residual common bile duct stones after LC can reduce the incidence of postoperative residual bile duct stones.

Abstract:
Objective To investigate the association between Y- box binding protein 1( YB- 1) overexpression and the prognosis of patients with intrahepatic cholangiocarcinoma( ICC) undergoing postoperative adjuvant chemotherapy.Methods The paraffin- embedded specimens were collected from 58 patients with ICC who underwent surgical treatment and postoperative adjuvant chemotherapy in The First Affiliated Hospital of Anhui Medical University from January 2010 to January 2015.Immunohistochemistry was used to measure the expression of YB- 1 in ICC tissue;after ICC cells were transfected with YB- 1 plasmid,the thiazolyl blue method was used to observe the change in gemcitabine sensitivity,and q PCR was used to observe the changes in the expression of multidrug resistance genes.The independent samples t- test was used for comparison of continuous data between two groups and a one- way analysis of variance was used for comparison of continuous data between multiple groups;the chi- square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to calculate survival rates and the log- rank test was used for survival difference analysis.Results Among the 58 patients,44( 75.9%) had high expression of YB- 1 in the cytoplasm of ICC cells( cytoplasm YB- 1 positive group) and 14( 24.1%)had no expression of YB- 1 in the cytoplasm of ICC cells( cytoplasm YB- 1 negative group).Of all patients in the cytoplasm YB- 1 positive group,18( 40.9%) also had positive nuclear expression of YB- 1( nuclear YB- 1 positive group);the other 40 patients had no nuclear expression of YB- 1( nuclear YB- 1 negative group).The nuclear YB- 1 negative group had a significantly longer survival time than the nuclear YB- 1 positive group( 63 months vs 28 months,χ~2= 17.99,P < 0.05).In the control plasmid group,the half- maximal inhibitory concentration( IC_(50)) of gemcitabine in HCCC- 9810 cells was 0.054 μmol,and in the p SG5- YB- 1 plasma transfection group,IC_(50) increased to 0.460 μmol after YB- 1 overexpression,which was 10 times higher than that in control plasmid group( P < 0.05).There was a significant increase in the YB- 1 transcriptional level after HCCC- 9810 cells were transfected with p SG5- YB- 1 plasmids( t =19.02,P < 0.05).After YB- 1 overexpression,HCCC- 9810 cells had significant increases in the transcriptional levels of multidrug resistance protein 1( MDR1) and multidrug resistance- associated protein 1( MRP1)( t = 13.34 and 11.35,both P < 0.05).Conclusion YB- 1 overexpression can be found in most ICC tissues,and nuclear positive expression of YB- 1 may indicate the poor effect of postoperative adjuvant chemotherapy,which may be associated with the increase in multidrug resistance after the expression of MDR1 and MRP1.

Liu HaiBo, Zhang BoJing, Lyu Yong, Han GuoHong
2017, 33(2): 348-353. DOI: 10.3969/j.issn.1001-5256.2017.02.033
Abstract:

Idiopathic non- cirrhotic portal hypertension( INCPH) is a rare disease,which is characterized by portal hypertension in the liver and the absence of liver cirrhosis,other liver diseases,or portal or hepatic vein thrombosis.At present,the research on the etiology of INCPH mainly focuses on the aspects of immune system diseases,chronic infections,exposure to drugs or toxins,genetic predisposition,and prothrombotic conditions or hypercoagulability.The main features of the clinical manifestations of INCPH are portal hypertension,splenomegaly,and hypersplenism,while liver injury,ascites,and hepatic encephalopathy are rare.Currently,there are no clear diagnostic criteria for INCPH,and a diagnosis is often made by exclusion.As for the treatment of INCPH,the therapeutic method recommended in the latest Baveno VI consensus is to follow the current guidelines for the treatment of cirrhotic portal hypertension.Since the majority of INCPH patients have good liver function,they have better prognosis compared with the patients with liver cirrhosis,but some of them may still develop liver failure and need liver transplantation.

2017, 33(2): 354-358. DOI: 10.3969/j.issn.1001-5256.2017.02.034
Abstract:
In clinical practice,up to 80% of patients with cirrhotic portal hypertension have varying degrees of gastrointestinal symptoms,which are associated with the changes in gastrointestinal structure,gastrointestinal dysfunction,and altered neurohumoral regulation.This article reviews the changes in gastrointestinal structure,gastrointestinal dysfunction,and altered neurohumoral regulation caused by cirrhotic portal hypertension,as well as the gastrointestinal clinical manifestations caused by such changes.It is pointed out that the research on the changes in gastrointestinal structure in cirrhotic patients with portal hypertension helps to effectively prevent and treat the complications of liver cirrhosis and improve gastrointestinal symptoms.In addition,the regulation of gastrointestinal function can improve patients' symptoms and delay the progression of liver cirrhosis.Therefore,it is recommended to regularly evaluate the changes in gastrointestinal mucosa and vessels in patients with liver cirrhosis,in order to provide early treatment and reduce complications.

2017, 33(2): 364-368. DOI: 10.3969/j.issn.1001-5256.2017.02.036
Abstract:
Hepatocellular carcinoma( HCC) complicated by arterioportal shunt( APS) is commonly seen in clinical practice,with an incidence rate of 28.8%- 63.2%.It is manifested as abdominal pain,diarrhea,and ascites and can also lead to serious complications of portal hypertension including gastrointestinal bleeding.Although there are various therapeutic methods,they tend to have poor clinical effects.APS is one of the most important causes of death in patients with HCC.This article introduces the etiology,typing,clinical manifestation,and therapies of HCC complicated by APS and points out that although there are various therapeutic methods for HCC complicated by APS,interventional treatment remains the most important method.The exploration of interventional treatment helps to improve patients' prognosis.

2017, 33(2): 369-374. DOI: 10.3969/j.issn.1001-5256.2017.02.037
Abstract:
Hepatocellular carcinoma( HCC) is a common malignant tumor in China with abundant blood supply.Conventional therapies may easily cause tolerance and patients tend to have poor prognosis.Combined with the hypoxia response elements of over a hundred of downstream target genes,hypoxia- inducible factor- 1α( HIF- 1α) in liver tissue participates in many processes including angiogenesis and glucose metabolism,inhibits the differentiation and apoptosis of tumor cells,and promotes the proliferation of tumor cells.High expression of HIF- 1α and its regulatory effect on angiogenesis- related factors are closely associated with patients' tolerance to radiotherapy and chemoradiotherapy,tumor invasion,metastasis,and prognosis.This article reviews the regulatory effect of abnormal expression of HIF- 1α in HCC cells on angiogenesis- related factors and their interrelation.

Qian Rui, Chen XiaoPeng
2017, 33(2): 394-399. DOI: 10.3969/j.issn.1001-5256.2017.02.042
Abstract:
Recurrence after surgery for common bile duct stones has not been solved properly,and recurrence of calculi often requires reoperation,which brings patients great pain and economic burden.Various risk factors may mediate the recurrence of common bile duct stones,including biliary tract infection,bile duct stenosis,cholangiectasis,cholestasis,Oddi sphincter dysfunction,abnormal bile composition,and surgical procedure.These risk factors are analyzed and related preventive measures are summarized.Current research findings show that prevention and treatment of risk factors for recurrence of calculi can reduce the recurrence rate of calculi and play an important role in preventing the recurrence of common bile duct stones.
