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.

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.

Retrospective analysis of endoscopic retrograde cholangiopancreatography in patients with prior Billroth Ⅱ gastrectomy / 中华消化内镜杂志

Objective To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography ( ERCP ) in the treatment of patients with biliary and pancreatic diseases after Billroth Ⅱ gastrectomy. Methods Clinical data of 178 patients with biliary and pancreatic diseases undergoing 237 times of ERCP at the digestive endoscopy center in Changhai Hospital from January 2011 to December 2016 were retrospectively collected. The success rate of procedures and related complications were summed up. Results Among 178 patients undergoing 237 times of ERCP, the successful intubation rate of the endoscope to reach the duodenal papilla was 83. 5％ ( 198/237 ) . The success rate of selective cannulation and completing the expected intervention were 91. 4％ ( 181/198 ) and 98. 9％ ( 179/181 ) , respectively. The total success rate of ERCP was 75. 5％ (179/237), which had an increasing trend with time. The total success rate of ERCP in patients with common bile duct stone was 85. 2％ ( 127/149) , and the stone retrieval rate during the first session was 56. 7％ (72/127). The ERCP-related complication rate was 14. 3％ ( 34/237 ) , with 1. 7％ ( 4/237 ) perforation, 1. 3％ ( 3/237 ) bleeding, 3. 4％ ( 8/237 ) pancreatitis, and 8. 0％ ( 19/237 ) asymptomatic hyperamylasemia. One patient with perforation and 2 patients with severe pancreatitis died of septic shock and multiple organ failure ( 1. 3％, 3/237 ) . Most ERCP-related complications were improved by conservative treatment or second endoscopic intervention ( 91. 2％, 31/34 ) . Conclusion ERCP is effective and safe in the treatment of biliary and pancreatic diseases in patients with prior Billroth Ⅱ gastrectomy. With the development of endoscopic techniques and experience accumulation of endoscopists, the success rate of intubation, selective cannulation and therapeutic intervention can be close to those of patients with normal anatomy, and the incidence of related complications is low.

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.

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.

Evaluation of effect of endoscopic retrograde cholangiopancreatography and laparoscopic bile duct exploration lithotomy in treatment of intra/extra-hepatic duct stones / 中国内镜杂志

Objective To investigate the therapeutic effects of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic bile duct exploration lithotomy (LBDEL) in treatment of intra/extra-hepatic duct stones. Methods There were 110 patients whose intrahepatic stones located in Ⅰ , Ⅱ hepatic duct and 378 patients whose stones only located in the common bile duct. These patients respectively underwent LBDE combined with choledochoscope laser lithotripsy or ERCP combined with endoscopic sphincterotomy (EST) and endoscopic nasobiliary drainage (ENBD) to remove the stones. Common bile ducts were performed primary suture or T tube placement in the LBDEL cases. The evaluation was carried out for perioperative complications and postoperative recovery of the surgical methods. Results The residual stone rate was 31.82% in 110 cases. The rate was higher in ERCP group (51.06%) than that in LBDEL group (17.46%) (P < 0.05). Postoperative recovery was better in LBDEL group than that in ERCP group. The residual stone rate was 8.20% in 378 cases. The rate was lower in ERCP group (3.68%) than that in LBDEL group(11.63%) (P < 0.05). Between the two groups, there had no statistical significance in postoperative recovery. The incidences of bile leakage and pulmonary infection were higher in LBDEL group than in ERCP group. The incidences of abdominal cavity infection, acute pancreatitis, digestive tract perforation and gastrointestinal bleeding were higher in ERCP group than that in LBDEL group. 2 of the 378 patients occurred death were happened digestive tract perforation which were induced during ERCP procedure. Conclusion LBDEL and ERCP demonstrated the same therapeutic effects in the treatment of common bile duct stones. However, ERCP has no large advantages in the treatment of hepatolithiasis, and shows higher complication rates. LBDEL has a significant curative effect for intra-and extrahepatic bile duct calculi and can maintain the integrity of Oddi sphincter. This technology is easy to spread to the basic-level hospital to benefit the majority of patients.

Clinical study on the treatment of senile choledocholithiasis with improved approach and bile duct approach of laparoscopic biliary tract exploration / 实用医学杂志

Objective To investigate the improved approach and bile duct approach of laparoscopic biliary tract exploration for the treatment of the elderly patients with common bile duct stones. Methods Ninety-two elderly patients with common bile duct stones were enrolled and randomly divided into the improved group and the conventional group ,with 46 cases in each group. The time of hemorrhage ,the time of common bile duct suture,the recovery time of gastrointestinal function,the time of hospitalization,body temperature,albumin and total bilirubin levels,complications and recurrence of stones were recorded and compared between the two groups. Results The time of hemorrhage,the time of common bile duct suture,the recovery time of gastrointestinal func-tion and the time of hospitalization in the improved group were lower than those in the conventional group(P<0.05, respectively). The body temperature of patients in the improved group was lower than that in the conventional group on 3 days after surgery(P<0.05). The overall incidence of postoperative complications in the improved group was lower than that in the conventional group (P < 0.05). No recurrence of stones was observed in both two groups. Conclusion The improved approach for laparoscopic common bile duct exploration surgery results in less bleed-ing,short common bile duct suture time,rapid postoperative recovery,less body temperature fluctuations and less complications,deserving popularization.

Short term effect of different diameters of ampulla balloon dilation in treatment of choledocholithiasis / 中国内镜杂志

Objective To investigate the short term efficacy and security of different diameters of ampulla balloon dilation in the treatment of choledocholithiasis. Methods 80 patients with extrahepatic bile duct stones treated by EPBD were included in this study. All the patients were divided into 8 mm group, 10 mm group, 12 mm group, 14 mm group, which were according to the diameter of common bile duct (CBD) and stones. CBD stones were removed with retrieved balloon, Dormia basket, and/or mechanical lithotripsy if necessary. The incidence of 24 h hemorrhage, acute pancreatitis, hyperamylasemia and intestinal perforation were observed, and the incidence of pneumobilia and duodenobiliary reflux two weeks after EPBD. Then analyzed the short-term efficacy of the four groups. Result The overall success of stone removal in all groups were 100.0%, there was no significant differences in bleeding, intestinal perforation, hyperamylasemia, pancreatitis between each group (P > 0.05) . There shows significant differences in pneumobilia and duodenobiliary reflux two weeks after EPBD (P < 0.05). The incidence of pneumobilia and duodenobiliary reflux increased with the size of the balloon. Conclusion The application of EPBD is effective and safe for bile duct stone removal, while with the increasing of balloon diameter, the function of Oddi sphincter has severely influenced.

Case-control study on necessity of cholecystectomy for patients with bile duct stones combined with gallbladder stones after clearance of stones / 中华消化内镜杂志

Objective To discuss necessity of cholecystectomy for patients with stones in their bile ducts and gallbladders in the absence of absolute operation indications of cholecystectomy after clearance of bile duct stones with ERCP. Methods Data of less than 70-year-old patients with stones in their bile ducts and gallbladders but without absolute operation indications of cholecystectomy admitted to the First People′s Hospital of Hangzhou from January 2012 to December 2014 were retrospectively analyzed. Patients were divided into cholecystectomy group and gallbladders in situ group after bile duct stones removal with ERCP. The hospitalization time, recurrent biliary events, complications of operation were compared between two groups. Results A total of 128 patients were included and followed up for(24.031±9.170)months with 64 cases in conservative group and 64 cases in cholecystectomy group. Incidence of recurrent biliary events in the cholecystectomy group and conservative group were 7.8%(5/64)and 10.9%(7/64)(P=0.544). Among cases of recurrent biliary events,incidences of cholangitis in the two groups were 7.8%(5/64)and 4.7%(3/64)respectively(P= 0.465), incidences of pancreatitis were 0(0/64)and 1.6%(1/64) respectively(P=0.315), incidences of common bile duct stones were 7.8%(5/64)and 7.8%(5/64)respectively(P = 1). No recurrent cholecystitis occurred. There were no differences in ERCP-related complications between the cholecystectomy group[23.4%(15/64)]and the conservative group[12.5%(8/64)](P=0.107). But 4 patients(6.3%)in cholecystectomy group had LC-related complications during the follow-up period, 3 cases of infection and 1 ileus. The hospital stay in conservative group was shorter than that in cholecystectomy group(5.906± 4.614 days VS 14.313± 6.312 days, P<0.001). The hospitalization expenses in two groups were(45 196± 12 518)yuan and(22 160± 11 755)yuan(P<0.001). Conclusion Conservative methods yield to shorter hospitalization and lower expenses without cholecystectomy-related complications. Conservative management for gallbladder stones after ERCP for biliary duct stones is recommended for patients who had no absolute operation indications of cholecystectomy.
