Tratamiento endoscópico de las estenosis poscolescistectomía de la vía biliar / Endoscopic treatment of postcholecystectomy bile duct stenosis

Introducción: La estenosis de la vía biliar es una afección poco frecuente, pero con serias repercusiones en la morbilidad de los pacientes. La gran mayoría ocurre después de la cirugía hepatobiliar: la colecistectomía es la más común de estas cirugías. El reconocimiento temprano y el enfoque multidisciplinario adecuado es la piedra angular para lograr obtener resultados finales óptimos. Objetivo: Describir el tratamiento endoscópico de los pacientes con estenosis poscolescistectomía atendidos en el Instituto de Gastroenterología (Cuba). Métodos: Se realizó un estudio retrospectivo descriptivo de los pacientes con diagnóstico de estenosis biliar poscolescitectomía. Se determinaron variables sociodemográficas, clínicas y endoscópicas de interés. Resultados: Se estudiaron 16 pacientes. Predominaron las mujeres menores de 50 años. El 75 por ciento de los pacientes tenían antecedente de colecistectomía laparoscópica. Las estenosis biliares tipo I y III, según la clasificación de Bismuth, fueron las más usuales. El tratamiento endoscópico mediante colangiografía retrógrada endoscópica (CPRE) con colocación de múltiples prótesis plásticas fue la conducta terapéutica más empleada. Conclusiones: En las estenosis poscolescitectomía los procedimientos endoscópicos se han convertido en el tratamiento de elección, como un procedimiento menos invasivo, con baja morbilidad y mortalidad, con evidentes resultados comparables a los logrados con procedimientos quirúrgicos no endoscópicos(AU)

Introduction: Bile duct stenosis is an infrequent condition, but it seriously affects patient morbidity. The vast majority of cases occur after hepatobiliary surgery, cholecystectomy being the most common of such surgeries. Early recognition and an appropriate multidisciplinary approach are the cornerstones to achieve optimal final results. Objective: Describe the endoscopic treatment of patients with postcholecystectomy stenosis cared for at the Institute of Gastroenterology in Cuba. Methods: A retrospective descriptive study was conducted of the patients diagnosed with postcholecystectomy bile duct stenosis. Determination was made of sociodemographic, clinical and endoscopic variables of interest. Results: A total 16 patients were studied. There was a predominance of women aged under 50 years. 75 percent of the patients had a history of laparoscopic cholecystectomy. The most common bile duct stenoses were types I and III by Bismuth's classification. The most frequent therapeutic management was endoscopic treatment by endoscopic retrograde cholangiography (ERCP) with placement of multiple plastic prostheses. Conclusions: Endoscopic procedures have become the treatment of choice in postcholecystectomy stenosis. They are less invasive, their morbidity and mortality are low, and their results are comparable to those of non-endoscopic surgical procedures(AU)

Expressions and significance of transforming growth factor β1, Survivin and Caspase-3 in patients with intrahepatic bile duct stones and bile duct stenosis / 中华肝胆外科杂志

Objective To investigate the expressions and the significance among the three markers TGF β1,Survivin and Caspase-3 in intrahepatic bile duct tissues in patients with intrahepatic bile duct stones.Method Total of 130 paraffin section of intrahepatic bile duct tissue were collected at Department of Pathology,The 904th Hospital of Joint Logistic Support Force of PLA from 2013 to 2018.Total of 50 patients with intrahepatic bile duct stones complicated with bile duct strictures (the stenosis group),40 patients with intrahepatic bile duct stones with chronic inflammation (the inflammation group),and 40 patients with normal liver tissues (the normal control group) were included in this study.The expressions of TGF β1,Survivin and Caspase-3 in liver tissues were detected by immunohistochemistry and compared among the 3 groups to find their correlations with the clinicopathological features of the disease of the patients.Results TGF β1 was expressed in 72.0％ of the patients in the stenosis group,37.5％ in the inflammatory group,and 15.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05);Survivin was expressed in 78.0％ of the patients in the stenosis group,47.5％ in the inflammatory group,and 25.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05);Caspase-3 was expressed in 10.0％ of the patients in the stenosis group,42.5％ in the inflammatory group,and 75.0％ in the normal control group.The differences among the groups were significant (P ＜ 0.05).Within the stenosis group,TGF β1 was negatively correlated with Caspase-3 (r =-0.882,P ＜ 0.05),and positively correlated with Survivin (r =0.889,P ＜ 0.05).Survivin and Caspase-3 were also negatively correlated (r=-0.923,P＜0.05).Conclusion Abnormal expressions of TGF β1,Survivin and Caspase-3 were involved in the formation of intrahepatic bile duct stones associated with bile duct strictures.

Clinical value of SpyGlass DS cholangioscopy in diagnosis and treatment of patients with biliary tract diseases (with video) / 中华消化内镜杂志

Objective To evaluate the clinical application value of SpyGlass DS cholangioscopy in diagnosis and therapy of patients with biliary tract diseases. Methods Seven patients with biliary tract diseases were examined and treated with SpyGlass DS system. Three patients with large choledocholithiasis underwent laser lithotripsy under SpyGlass DS system, and then the broken stones were removed by ERCP. Four patients with indeterminate bile duct stricture underwent SpyGlass DS examination and SpyGlass DS-guided biopsies if necessary.Results SpyGlass DS cholangioscopy was successfully performed in all patients with a mean procedure time of 12. 6 min. Complete stone clearance was achieved in 3 patients with large biliary stones. Of the 4 patients with indeterminate biliary stricture, 2 underwent SpyGlass DS-guided biopsies and were diagnosed as malignant biliary tumor; the other 2 patients were diagnosed as inflammatory bile duct stenosis after visualizing the target lesions without biopsy. Two patients developed hyperamylasemia after the procedure, and recovered spontaneously. Conclusion SpyGlass DS cholangioscopy can provide accurate diagnosis in indeterminate biliary strictures and facilitate therapy in patients with challenging biliary stones.

Diagnostic value of endoscopic ultrasonography for distal bile duct stenosis / 中华消化内镜杂志

Objective To study the diagnostic value of endoscopic ultrasonography (EUS)for benign and malignant bile duct stricture.Methods Data of 51 patients who underwent EUS from January 2007 to March 2015 due to distal biliary stricture were retrospectively studied.And their diagnosis with EUS,IDUS,bile duct cytological brushing and final diagnosis were compared.Results Malignant bile duct stenosis were finally confirmed in 19 cases and benign stenosis were confirmed in 32 cases.The sensitivity (73.7％ VS 57.1％) and positive predictive value (73.7％ VS 57.1％) of EUS for the benign and malignant diagnosis of biliary tract stenosis were significantly higher than that of IDUS (P＜0.05),while their specificity(84.4％ VS 84.2％)and accuracy(80.4％ VS 76.9％)were similar.The sensitivity of EUS was significantly higher than that of bile duct cytological brushing (73.7％ VS 50.0％),while their specificity (84.4％ VS 100.0％)and accuracy(80.4％ VS 81.6％)were similar.EUS findings of hypoechoic mass features had higher diagnostic accuracy for detecting malignant distal bile duct stricture than irregular thickening of the lumen in the distal bile duct (100.0％ VS 64.3％,P＜0.05).Conclusion For patients with lesions of the distal bile duct that CT/MRI could not diagnose,EUS has an important value for the further diagnosis of benign and malignant bile duct stricture.

Clinical application of ERCP in the treatment of bile duct stenosis after liver transplantation / 中华器官移植杂志

Objective To discuss the clinical application of individualized strategy of endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of bile duct stenosis after liver transplantation (LT).Methods Fifty-two patients,including 40 men and 12 women,aged 54.3 ± 9.1 years old,who suffered from bile duct stenosis and accepted 88 times of ERCP from June 2014 to May 2016 in our department were investigated.The procedures,clinical features and biochemical criteria were analyzed retrospectively.Results According to the treating occasions and clinical symptoms,single plastic stent,dilatation combined with single plastic stent,and dilatation combined with multiple plastic stents were chosen to use.ERCP in 8 patients out of 52 patients failed technically,and the therapeutic efficacy was 82.7％.The treatment duration was 8.2 ± 2.9 months.The recurrence rate was 4.7％ (2 cases) during the follow-up period.The most common complications were postERCP pancreatitis (2.3％) and cholangitis (3.4％),which would be cured by conservative treatment in most cases.Conclusion ERCP,as an effective and safe method,could be used as the first choice or bridge treatment for bile duct stricture after LT.We recommend individualization strategy,including step by step mode and different combinations of PTC or endoscopic procedures,in order to improve clinical efficacy of all kinds of stricture.

Short and long term effects of the low-big hole choledochoduodenostomy / 中国综合临床

Objective To investigate the indications and clinical effect of the low-big hole choledochoduodenostomy. Methods Two hundred and ninty-eight patients, had bile duct stone accompanied with common bile duct lower segment stenosis, were prospectively enrolled into the study and randomly divided into the low-big hole choledochoduodenostomy (improved CD ) group (n = 148 ) and the Roux-en-Y choledochojejunostomy (CJ) group (n = 150). Their perioperative period and long term effect indices were recorded and compared. Results Perioperative period indices:The time of cholangio-jejunostomy was much shorter in improved CD group than the CJ group ([31.0±10.5] min vs [53.0±12.3] min, P＜0.001);The anastomotic leakage was significantly less in improved CD group than the CJ group (2 vs 9, P ＜ 0. 001 ). The long term effect indices: The occurrence of peptic ulcer (3 vs 15 ) and the bile duct cecum or blind loop syndrome (5 vs 158) were significantly lower in group improved CD group than CJ group (Ps＜0.01);The occurrence of bile duct backflow (70 vs 42) was significantly higher in improved CD group than CJ group (P＜0. 0l). Conclusion The clinical effect of the low-big hole choledochoduodenostomy gastrointestinal had excellent effect for bile duct stone accompanied with common bile duct lower segment stenosis, especially for old,weak and critical patients,and it can not be replaced by the Roux-en-Y choledochojejunostomy.

Management Strategy for Congenital Choledochal Cyst with Co-existing Intrahepatic Dilation and Aberrant Bile Duct As Well As Other Complicated Biliary Anomalies

The purpose of this study was to investigate and discuss imaging methods and management strategies for congenital choledochal cyst with co-existing intrahepatic dilation and aberrant bile duct as well as other complicated biliary anomalies. In this study we reviewed and analyzed 72 patients with congenital choledochal cyst, ranging in age from 15 days to 12 years old and who were seen at our hospital during the past 12 years, from January 1993 to October 2005. The image manifestation and clinical significance of patients with co- xisting intrahepatic biliary dilation and aberrant bile duct were carefully examined during operation via MRCP, cholangiography and choledochoscope. Twenty-two cases (30.1%) presented with intrahepatic bile duct dilation and 12 of these were of the cystic type. That is, the orifice of the dilated intrahepatic tract that converged into the common hepatic duct showed membrane or septum-like stenosis. In 10 cases the dilation tapered off from the porta hepatis to the initiating terminals of the intra-hepatic bile ducts and was not accompanied by stenosis. An aberrant bile duct was observed in 2 of the cases. In 3 cases, the right and left hepatic ducts converged at the choledochal cyst. In conclusion, the imaging methods for intrahepatic bile duct dilation possess important clinical significance. Further, for hepatojejunostomy with radical excision of a choledochal cyst, additional operative procedures for intrahepatic stenosis, possible bile duct malformation and pancreaticobiliary common duct calculi can potentially reduce postoperative complications.
