Synchronous laparoscopic cholecystectomy combined with laparoscopic common bile duct exploration or combined with endoscopic sphincterotomy for gallstones with common bile duct stones / 中华普通外科杂志

Objective:To compare the recurrence of common bile duct stones (CBDS) in patients with gallstones and concurrent CBDS treated by two surgical approaches: synchronous laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) (LC+LCBDE) and synchronous LC combined with intraoperative endoscopic sphincterotomy (IO-EST) (LC+IO-EST).Methods:From Apr 2013 to Apr 2020, the clinical data of 903 patients with gallstones with CBDS who were admitted to the Clinical Medical College, Yangzhou University were retrospectively analyzed.Results:Based on the chosen surgical method, we categorized 389 cases into group A (LC+LCBDE) and 514 cases into group B (LC+IO-EST). Our findings revealed that group A had a significantly lower rate of CBDS recurrence and re-recurrent CBDS compared to group B (4.4% vs. 8.4%, P=0.024; 0.8% vs. 3.1%, P=0.010). Moreover, Logistic regression analysis after inverse probability of treatment weighting, revealed that the surgical approach implemented in group A was an independent protective factor of recurrent CBDS and second recurrence of CBDS ( OR=0.482, 95% CI: 0.365-0.637, P<0.001; OR=0.118, 95% CI:0.080-0.173, P<0.001). Conclusion:LC+LCBDE is an optimal treatment option to LC+IO-EST for patients with gallstones combined with CBDS and common bile duct ≥8 mm.

Clinical study of three-dimensional reconstruction combined with intraoperative ultrasound precise hepatectomy in complicated intrahepatic bile duct stones / 中华肝胆外科杂志

Objective:To evaluate the efficacy of preoperative three-dimensional (3D) image reconstruction combined with intraoperative dynamic ultrasonography (IOUS) in laparoscopic precision hepatectomy for intrahepatic bile duct stones.Methods:The clinical data of 66 patients with intrahepatic bile duct stones undergoing laparoscopic hepatectomy in the First People's Hospital of Fuyang District, Hangzhou from January 2018 to January 2023 were retrospectively analyzed, including 32 males and 34 females, aged (49.6±15.2) years old. Patients were divided into the study group ( n=32), who underwent laparoscopic precision hepatectomy using 3D reconstruction combined with IOUS, and the control group ( n=34), who underwent conventional laparoscopic hepatectomy. Perioperative data including the operation time, intraopera-tive blood loss, total volume of drainage on postoperative day (POD) 3, and the rates of complications were compared between the groups. Serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), liver function indices including total bilirubin (TBil) and alanine aminotransferase (ALT) were monitored preoperatively and on POD 1, 3, 5, and 7. Results:The operation time was shorter in the study group [(178±17) min vs. (189±18) min, t=2.55, P=0.010]. The intraoperative blood loss was reduced in the study group [(218±19) ml vs. (395±21) ml, P<0.001]. The incidence of total volume of drainage >300 ml on POD 3 were comparable between the groups [9.4%(3/32) vs. 14.7%(5/34), P=0.507]. There were no significant differences in preoperative serum level of TBil, ALT, CRP and IL-6 between the groups (all P>0.05). Compared to the control group, serum levels of TBil, ALT and CRP in the study group were decreased on POD 1, 3, 5 and 7, and IL-6 was decreased on POD 1 and 3 (all P<0.05). The occurrences of postoperative bile leakage [9.4% (3/32) vs. 29.4% (10/34)] and liver cutting surface fluid accumulation [12.5% (4/32) vs. 35.3% (12/34)] and the rate of stone retention [3.0% (1/32) vs. 20.6% (7/34)] were lower in the study group (all P<0.05). Conclusion:Preoperative 3D image reconstruction combined with IOUS in laparoscopic precision hepatectomy for intrahepatic bile duct stones could reduce intra-operative blood loss, hepatic inflammatory response, and postoperative complications.

Efficacy and safety of digital cholangioscopy-assisted non-radiation endoscopic retrograde cholangiopancreatography for common bile duct stones / 中华消化内镜杂志

Objective:To evaluate the efficacy and safety of digital cholangioscopy-assisted non-radiation endoscopic retrograde cholangiopancreatography (ERCP) for common bile duct stones.Methods:Clinical data of patients who underwent digital cholangioscopy-assisted non-radiation ERCP for common bile duct stones from May 2019 to September 2021 were reviewed. The baseline data, the success rate of cannulation, the one-time success rate of endoscopic stone removal, the operation time, total hospital stay, complications, and recurrence of bile duct stones were analyzed.Results:A total of 170 patients were included, and bile duct stones were detected in 156 (91.8%) patients with the long diameter of 7.7±4.1 mm under preoperative imaging examination. Bile duct stones were detected under choledochoscopy and were successfully removed by using digital cholangioscopy through non-radiation ERCP. The success rate of cannulation was 100.0% (170/170) . The one-time success rate of endoscopic stone removal was 96.5% (164/170), and 6 patients (3.5%) received secondary stone removal for large stones (long diameter>30 mm).The time of biliary exploration and whole non-radiation ERCP were 9.6±2.7 min (6-24 min) and 35.9±17.3 min (13-85 min), respectively. The total hospital stay was 6.3±2.2 days (5-10 days). Postoperative pancreatitis occurred in 3 patients (1.8%), all of whom were mild and resolved after symptomatic treatment. No recurrence of bile duct stones was seen in any patient over 1-month postoperative follow-up.Conclusion:Digital cholangioscopy-assisted non-radiation ERCP is safe and effective for common bile duct stones without ray exposure, which is worth of promotion.

Laparoscopic Common Bile Duct Exploration for Treatment of Common Bile Duct Stones:Clinical Analysis of 158 Cases / 中国医学科学院学报

Objective To evaluate the safety and effectiveness of laparoscopic common bile duct exploration in the treatment of common bile duct stones. Methods A retrospective analysis was conducted for 158 patients with cholecystolithiasis and choledocholithiasis admitted to the Number One Hospital of Zhangjiakou from January 2015 to December 2019.The patients were assigned into three groups according to the diameters of cystic duct and common bile duct,degrees of abdominal infection and tissue edema,and operation method.Group A(16 cases):laparoscopic cholecystectomy,transcystic choledochoscopic exploration for stone removal;Group B(94 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,T tube drainage;Group C(48 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,primary closure of the common bile duct.The operation time,residual rate of stones,and complication(bleeding,bile leakage,and wound infection) rate were compared between groups. Results The operation time of groups A,B,and C was(95.1±14.7),(102.2±18.1),(110.1±16.4) minutes,respectively,which showed no statistical difference between each other(F=0.020,P=0.887).One case in group A had residual stones,while no residual stone appeared in groups B and C.The overall stone clearance rate was 99.4% and the overall complication rate was 1.9%.There was no perioperative death. Conclusion It is generally safe and effective to carry out laparoscopic cholecystectomy and common bile duct exploration for stone removal in suitable populations.

Litiasis coledociana de difícil resolución / Difficult common bile duct stones

RESUMEN Antecedentes: el manejo laparoscópico en un tiempo de la coledocolitiasis se acompaña de una tasa de éxito elevada en la mayoría de los casos. Una excepción a esto son los cálculos coledocianos difi cultosos. Objetivo: describir los resultados del manejo de cálculos coledocianos dificultosos. Material y métodos: revisión retrospectiva de una serie consecutiva de casos de cálculos coledocianos dificultosos tratados durante el período 2018-2020. Resultados: 8 pacientes cumplieron con el criterio de inclusión. El manejo en un tiempo por videola paroscopia (5 casos) tuvo un 60% de conversión a cirugía abierta. Los otros pacientes (3 casos) fueron manejados inicialmente con endoscopia biliar por colangitis grave y fueron resueltos luego en forma electiva por instrumentación transcística. Conclusión: esta experiencia inicial sugiere que el abordaje en dos tiempos podría favorecer la resolu ción mininvasiva de los cálculos coledocianos dificultosos.

ABSTRACT Background: Single-stage procedure for the treatment of choledocholithiasis by laparoscopy is associated with high success rate in most cases. Difficult common bile duct stones are an exception to this rule. Objective: The aim of this study is to describe the results obtained with the management of difficult common bile duct stones. Material and methods: We conducted a retrospective review of a consecutive series of cases of difficult common bile duct stones treated between 2018-2020. Results: Eight patients fulfilled the inclusion criteria. Of the 5 patients managed with single-stage approach through video-assisted laparoscopy, 60% required conversion to open surgery. The other 3 cases were initially managed with endoscopic cholangiography due to severe cholangitis and were solved with elective transcystic instrumentation. Conclusion: This initial experience suggests that the two-stage approach could be better to treat difficult common bile duct stones with a minimally invasive approach.

Abordaje laparoscópico sistemático de la coledocolitiasis / Routine laparoscopic management of common bile duct stones

RESUMEN Antecedentes: la prevalencia conjunta de litiasis vesicular y coledociana aumenta con la edad y llega al 15% en la octava década de la vida. Su manejo continúa siendo controvertido: algunos profesionales prefieren el abordaje en un tiempo por videolaparoscopia, y otros, el abordaje en dos tiempos con endoscopia (CPRE preoperatoria) seguida de colecistectomía laparoscópica. Objetivo: evaluar la eficacia y seguridad del manejo en un tiempo por videolaparoscopia en pacientes consecutivos con diagnóstico de litiasis vesicular y coledociana. Material y métodos: estudio retrospectivo con datos de una base de datos prospectiva, entre julio de 2008 y julio de 2018. Resultados: sobre un total de 2447 colecistectomías laparoscópicas realizadas en el citado período, 416 (17%) presentaron litiasis coledociana. El éxito global de la vía transcística en la extracción de litiasis coledociana fue del 81,2%: del 70,4% en los casos con diagnóstico prequirúrgico de colestasis extrahepática litiásica y del 92,9% en los otros diagnósticos. La morbilidad fue del 4%, sin mortalidad ni lesiones quirúrgicas de la vía biliar. Conclusión : el manejo en un tiempo por videolaparoscopia es eficaz y seguro debido al elevado éxito global de la instrumentación transcística (ITC). El diagnóstico preoperatorio de coledocolitiasis condi ciona una disminución de esa eficacia, por mayor indicación de coledocotomía, con un aumento de la morbilidad y del tiempo de internación.

ABSTRACT Background: The prevalence of common bile duct stones associated with cholelithiasis increases with age and is about 15 % in the 8th decade of life but its management is still controversial. Some surgeons prefer the single-stage approach with laparoscopy while others suggest the two-stage management with preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy. Objective: The aim of the present study was to evaluate the efficacy of feasibility of single-stage laparoscopic surgery in patients with cholelithiasis and choledocholithiasis. Material and methods: We conducted a retrospective study with prospectively collected data between July 2008 and July 2018. Results: Of 2447 laparoscopic cholecystectomies performed during the study period, 416 presented common bile duct stones. The global success of the transcystic approach to clear common bile duct stones was 81.2%, 70.4% in the cases with preoperative diagnosis of choledocholithiasis and 92.9% for other diagnoses. The rate of complications was 4% without deaths or bile duct injuries. Conclusion: Single-stage laparoscopic surgery is an efficient and safe approach based on the high global success of transcystic exploration. The preoperative diagnosis of choledocholithiasis reduces the efficacy of the procedure due to greater indication of choledocotomy, with complications and longer length of hospital stay.

Epidemiological profile, referral routes and diagnostic accuracy of cases of acute cholangitis among individuals with obstructive jaundice admitted to a tertiary-level university hospital: a cross-sectional study

ABSTRACT BACKGROUND: Obstructive jaundice may lead to ominous complications and requires complex diagnostic evaluations and therapies that are not widely available. OBJECTIVE: To analyze the epidemiological profile, referral routes and diagnostic accuracy at admittance of cases of acute cholangitis among patients with obstructive jaundice treated at a referral unit. DESIGN AND SETTING: Cross-sectional study at a tertiary-level university hospital. METHODS: Patients with obstructive jaundice who were treated by means of endoscopic retrograde cholangiopancreatography, resection and/or surgical biliary drainage were evaluated. The main variables analyzed were epidemiological data, referral route, bilirubin levels and time elapsed between symptom onset and admittance and diagnosing of acute cholangitis at the referral unit. The accuracy of the clinical diagnosis of acute cholangitis was compared with a retrospective analysis on the medical records in accordance with the Tokyo criteria. RESULTS: Female patients predominated (58%), with an average age of 56 years. Acute cholangitis was detected in 9.9% of the individuals; application of the Tokyo criteria showed that the real prevalence was approximately 43%. The main referral route was direct contact (31.8%) and emergency care (29.7%); routing via official referral through the public healthcare system accounted for 17.6%, and internal referral from other specialties, 20%. The direct route with unofficial referral was the most important route for cases of neoplastic etiology (P < 0.01) and was the fastest route (P < 0.01). CONCLUSIONS: There is a deficiency in the official referral routes for patients with obstructive jaundice. The accuracy of the clinical diagnosis of acute cholangitis was poor. Wider dissemination of the Tokyo criteria is essential.

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.

A retrospective study on 1 152 patients with common bile duct stones / 中华肝胆外科杂志

Objective To analyze the incidence of choledocholithiasis in patients who underwent cholecystectomy in our hospital,and to determine the incidences of recurrent stones and choledocholithiasis combined with cholangitis after treatment for choledocholithiasis.Methods A retrospective study was conducted on 1 152 patients with common bile duct stones treated from January 2013 to July 2017 in our hospital.Results Of the 1152 patients with common bile duct stones,572 patients had a history of cholecystectomy,accounting for 49.65％ of all patients.402 patients had choledocholoithiasis combined with cholecystolithiasis (34.9％ of all patients),278 patients had choledocholithiasis without cholecystolithiasis (24.1％).Choledocholithiasis could occur after cholecystectomy.The time of onset of choledocholithiasis was 5 ～ 10 years after operation in 49.1％ of patients,and 200 of these patients with choledocholithiasis were treated with lithotripsy.There were 110 patients who underwent choledocholithotomy and cholecystectomy,and 90 patients who underwent ERCP and stone removal.There was no significant difference between the 2 groups (P ＞ 0.05).Choledocholithiasis complicated with cholangitis developed in 511 patients (44.3％ of all patients).These included 437 patients with acute mild cholangitis (85.5％) and acute obstructive suppurative cholangitis (14.5％).Recurrent choledocholithiasis combined with acute cholangitis after choledocholithotomy developed in 51 patients,and recurrent choledocholithiasis combined with cholangifts developed after ERCP in 50 patients.There was no significant difference between the two groups (P ＞0.05).Conclusions Choledocholithiasis after cholecystectomy accounted for a high proportion of patients.Recurrent choledocholithiasis could occur after choledocholithotomy.Common bile duct stones were susceptible to develop cholangitis.Thus,common bile duct stones should be treated as soon as possible.

Exploración laparoscópica de las vías biliares. Descripción de la técnica paso a paso. Video / Laparoscopic exploration of the bile ducts. Description of the technique step by step. Video

La exploración laparoscópica de las vías biliares (ELVB) constituye, hoy en día, una herramienta de gran utilidad en el tratamiento de la patología litiásica del árbol biliar, especialmente cuando técnicamente sea imposible realizar una pancreato-colangiografía retrógrada endoscópica (PCRE) o en los casos en los cuales este estudio no esté disponible. Método: Describir mediante un video nuestra técnica de ELVB paso a paso, en una paciente de 41 años quien consultó por presentar tinte ictérico en piel y mucosas, coluria e hipocolia. El ultrasonido abdominal reportó litiasis vesicular, dilatación de vías biliares intra y extra hepáticas, colédoco de 9 mm de diámetro y múltiples imágenes hiperecogénicas sugestivas de litiasis. Al no poder realizarse PCRE se decide practicar ELVB. Se realizó disección del triángulo biliocístico, identificación y ligadura proximal del conducto cístico con la finalidad de evitar la migración de cálculos a la vía biliar durante el procedimiento, coledocotomía, lavado proximal y distal de la vía biliar, exploración con catéter de Fogarty, coledocorrafia primaria, cisticotomía y colocación de catéter para colangiografía intraoperatoria, constatación de plenificación de las vías biliares sin imágenes de defecto y de adecuado paso del contraste al duodeno, colecistectomía y colocación de drenaje subhepático. Resultados: Paciente evoluciona en forma satisfactoria, egresando al tercer día de postoperatorio sin eventualidades. Discusión: La ELVB con coledocorrafia primaria ha sido descrita como una alternativa viable y efectiva para el manejo de la litiasis biliar, destacando su menor morbimortalidad cuando se compara con procedimientos endoscópicos como la PCRE(AU)

Laparoscopic common bile duct exploration (LCBDE) constitutes, nowadays, a very useful tool in the treatment of biliary tree lithiasis, especially when it is technically impossible to perform an endoscopic retrograde pancreatic cholangiography (ERCP) or in cases when this study is not available. Method: Using a video, we describe our LCBDE technique step by step, in a 41-year-old patient who consulted for presenting jaundiced skin and mucosa, coluria and hypocolia. Abdominal ultrasound reported gallstones, intra- and extra-hepatic bile duct dilation, a 9-mm diameter common bile duct (CBD) and multiple hyperechoic images suggestive of lithiasis. Since ERCP could not be performed, it was decided to practice LCBDE. Dissection of the Calot's triangle was performed, identification and proximal ligation of the cystic duct in order to avoid migration of stones to the common bile duct during the procedure, choledochotomy, proximal and distal lavage of the bile duct, exploration with a Fogarty catheter, primary closure of CBD, cysticotomy and placement of catheter for intraoperative cholangiography, verification of fullness of the bile ducts without defect images and adequate passage of contrast to the duodenum, cholecystectomy and placement of subhepatic drainage. Results: Patient progressed satisfactorily, being discharged on the third postoperative day, uneventfully. Discussion: LCBDE with primary closure of CBD has been described as a viable and effective alternative for the management of biliary stones, highlighting its lower morbidity and mortality when compared with endoscopic procedures such as ERCP(AU)

Curative effect of drugs on the prevention of bile duct stones recurrence after ERCP / 中国内镜杂志

Objective To evaluate the curative value of the tauroursodeoxycholic acid (TUDCA) and Danning table (DN) in the prevention of bile duct stones recurrence after ERCP. Methods 210 patients with Choledocholithiasisby ERCP were randomly divided into 3 groups. The patients in the control group were not given any medicine. The patients in the TUDCA group took TUDCA every night. The patients in the DN group took Danning tablets of three times a day. The course of medication and followed up for the patients was 24 months after the operation. All the patients would be examined regularly by Biliary color doppler ultrasound and MRCP. The recurrence rates of Choledocholithiasis, cholesterol saturation index and serum lipid were recorded and compared statistically between the three groups. Results In total, 190 patients completed the treatment and follow-up according to the experimental design. The recurrence rates of the control, TUDCA and DN group were 17.46%(11/63), 6.34% (4/63) and 10.94% (7/64). The recurrence rates in the TUDCA and DN group were significantly lower than those the control group (P < 0.05).The recurrence rate in the TUDCA group was significantly lower than that in the DN group; On the tenth days after the operation, the CSI in the TUDCA were significantly lower than those the control group and the DN group (P < 0.05). There was no statistically significant difference between the DN group and the control group (P > 0.05); To the patients without recurrence, the level of TC, LDL in the TUDCA group were significantly lower than those the control group and and the DN group (P < 0.05). The level of HDL in the TUDCA group were significantly higher than those the control group and and the DN group (P < 0.05). There was no statistically significant difference on the level of HDL between the DN groupand the control group (P > 0.05). Conclusion The application of TUDCA and DN for patients with Choledocholithiasis after ERCP can effectively reduce the recurrence rates, the curative effect of TUDCA more than DN.

Laparoscopic assisted small incision biliary tract exploration in treatment of recurrent extrahepatic bile duct stones / 中华肝胆外科杂志

Objective To compare the clinical results between laparoscopic assisted small incision biliary duct exploration with traditional biliary exploration for patients with recurrent extrahepatic bile duct stones who had undergone biliary surgery for ≥2 times.Methods The clinical data of patients with recurrent extrahepatic bile duct stones who had undergone biliary surgery for ≥2 times,and underwent laparoscopic assisted small incision biliary duct exploration or traditional biliary exploration from September 2011 to June 2016 were retrospectively studied.Results 23 patients underwent laparoscopic assisted small incision biliary duct exploration (Group A),and 24 patients underwent traditional biliary exploration (Group B).The time spent on abdominal adhesion separation in group A and group B was (74.7 ± 20.5) min and (90.8 ± 20.3) min (P ＜ 0.05),respectively.The amount of intraoperative blood loss were (67.4 ± 35.6)ml and (107.4±31.5) ml (P ＜0.05).The number of patients with intestinal injury were 0 and 4.The postoperative time to first pass flatus was (26.9 ± 3.8) h and (35.5 ± 6.5) h (P ＜ 0.05).The durations of postoperative hospital stay were (8.1 ± 1.4) d and (12.8 ± 2.9) d,respectively,(P ＜ 0.05).The numbers of patients who required postoperative analgesics were 10 and 19 cases (P ＜ 0.05).The number of patients with postoperative incisional wound infection were 1 and 6.There was no significant difference in the time spent on biliary exploration,incidences of biliary leakage,pulmonary infection rate,hospitalization cost and liver function status between the two groups of patients (P ＞ 0.05).Conclusions Laparoscopic assisted small incision biliary duct exploration was safe and effective for patients with recurrent extrahepatic bile duct stones who had undergone biliary surgery for ≥2 times.This operation can be used as a preferred procedure.

A retrospective study of emergency endoscopic needle-knife sphincterotomy for acute severe cholangitis resulting from impacted common bile duct stones at duodenal papilla / 中华消化内镜杂志

Objective To evaluate the application value of emergency endoscopic needle-knife sphincterotomy(NKS) on acute cholangitis of severe type (ACST) resulting from impacted common bile duct stones at duodenal papilla. Methods A retrospective study was performed on the data of 90 ACST cases with impacted common bile duct stones at the native papilla and undergoing emergency NKS between January 2011 and January 2017 in Tianjin Nankai Hospital. The completion of treatment, mean operating time, impacted stone clearance rate, changes of laboratory indexes before and after endoscopic procedure, and complications were analyzed. Results All the 90 patients underwent emergency NKS successfully, with a total success rate of 100. 0％. The mean operating time was 25. 2±11. 7 min. The impacted stone clearance rate was 95. 6％(86/90). The complication rate was 5. 6％(5/90), including 3 cases of hemorrhage and 2 cases of post-ERCP pancreatitis. There was no procedure-related mortality. The postoperative white blood cell count, serum procalcitonin, total bilirubin, direct bilirubin, and glutamic-pyruvic transaminase decreased significantly compared with pre-operation ( all P<0. 001) . Conclusion Emergency NKS is effective and safe for treatment of ACST resulting from impacted common bile duct stones at duodenal papilla with a relative high application value.

Effect of endoscopic retrograde cholangiopancreatography on serum amyloid A, C-reactive protein and endothelin-1 in patients with acute gallstone cholangitis / 中华内分泌外科杂志

Objective To observe the efficacy of endoscopic retrograde cholangiopancreatography (ER-CP) and laparotomy in treatment of acute gallstone cholangitis and their impact on the levels of serum amyloid A (SAA),C-reactive protein (CRP) and endothelin-1 (ET-1).Methods 80 patients with acute gallstone cholangitis,from Jan.2013 to Dec.2016,were divided into observation group(35 cases) and the control group (45 cases)according to the surgical procedure.The observation group received ERCP,and the control group were performed with open cholecystectomy,common bile duct extraction and T-tube placement.The operation time,blood loss,gastrointestinal function recovery time,hospital stay,and the success rate of stone removal,and the levels of SAA,and changes in CRP and ET-1 before and after treatment were observed in each group.Results Compared with the control group,the observation group had shorter operative time [(76.43±9.82)min vs (69.28±7.53) min,P=0.000],less blood loss[(1 1.73±2.83)ml vs (78.41±3.28) ml,P=0.000],shorter gastrointestinal function recovery time [(29.53±3.27) h vs (78.33±8.43) h,P=0.000],and shorter hospital stay [(5.73±1.32)d vs (8.54±1.62) d,P=0.000],while the success rate of stone removal was not significantly different between the two groups (97.14％ vs 95.56％,P＞0.01).Before treatment,the levels of SAA,CRP and ET-1 had no significant difference between the two groups(P＞0.05).The levels of SAA,CRP and ET-1 in the two groups after treatment were significantly lower than those before treatment (P＜0.01),while the levels decreased more in the observation group compared with that in the control group (P＜0.01).Conclusions The endoscopic therapy and laparotomy in treatment of acute cholangitis stones have both achieved good efficacy.Compared ith laparotomy,ERCP has faster recovery,shorter hospital stay,and quicker subsided inflammation.
