METHODS: Prospective intention-to-treat analysis of patients referred for biliary cannulation following recent unsuccessful ERCP. RESULTS: Fifty-one patients (35 female; mean age: 62.5 years; age range: 40-87 years) with previous failed biliary cannulation were referred for repeat ERCP. The indication for ERCP was primarily choledocholithiasis (45%) or pancreatic malignancy (18%). Successful biliary can- nulation was 100%. The precut needle knife sphincterotomy (NKS) rate was 27.4%. Complications occurred in 3.9% (post-ERCP pancreatitis). An identif iable reason for initial unsuccessful biliary cannulation was present in 55% of cases. Compared to a cohort of 940 nave pa-pilla patients (female 61%; mean age: 59.9 years; age range: 18-94 years) who required sphincterotomy over the same time period, there was no statistical difference in the cannulation success rate (100% vs 98%) or postERCP pancreatitis (3.1% vs 3.9%). Precut NKS use was more frequent (27.4% vs 12.7%) (P = 0.017). CONCLUSION: Referral to a high-volume center following unsuccessful ERCP is associated with high technical success, with a favorable complication rate, compared to routine ERCP procedures.展开更多

Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 bleeding.Conclusions: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.展开更多

文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)serves an essential role in treating biliary diseases,especially in choledocholithiasis.However,due to the limited human lifespan,there remains a paucity of clinical investigations on ERCP treatment in patients over 90 years old.AIM To explore the effectiveness and safety of ERCP in super-older patients aged≥90 years with choledochal stones.METHODS This study retrospectively analyzed data from patients(aged≥65 years)with choledocholithiasis who received ERCP treatment in our hospital from 2011 to 2023.Among them,patients≥90 years old were in the super-older group,and patients aged 65-89 years were in the older group.Baseline data,including gender,number of stones,stone size,gallbladder stones,periampullary diverti-culum,and common bile duct intubation of patients in the two groups,were mat-ched by adopting the 1:1 propensity score matching method.RESULTS After matching,44 patients were included in both the super-older group and the older group.The incidence of stroke in the super-older group was markedly higher than that in the older group[34.1%(15/44)vs 6.8%(3/44),P=0.008].The success rate of the ERCP procedure in the super-older group was 90.9%(40/44),compared to that in the older group[93.2%(41/44),P=1.000].Although endo-scopic papillary balloon dilation was more frequently used in the super-older group than in the older group[61.4%(27/44)vs 18.2%(8/44),P<0.001],there was no significant difference in terms of stone removal rate,the incidence of complications,mortality,recurrence,and length of hospitalization between the two groups(P>0.05).CONCLUSION ERCP is safe and effective in super-older patients≥90 years old with choledocholithiasis.
文摘BACKGROUND Intrahepatic and extrahepatic bile duct stones(BDSs)have a high rate of residual stones,a high risk of recurrence,and a high rate of reoperation.It is very important to take timely and effective surgical intervention for patients.AIM To analyze the efficacy,postoperative rehabilitation,and quality of life(QoL)of patients with intra-and extrahepatic BDSs treated with endoscopic retrograde cholangiopancreatography(ERCP)+endoscopic papillary balloon dilation(EPBD)+laparoscopic hepatectomy(LH).METHODS This study selected 114 cases of intra-and extrahepatic BDSs from April 2021 to April 2024,consisting of 55 cases in the control group receiving laparoscopic common bile duct exploration and LH and 59 cases in the observation group treated with ERCP+EPBD+LH.Efficacy,surgical indicators[operation time(OT)and intraoperative blood loss(IBL)],postoperative rehabilitation(time for body temperature to return to normal,time for pain relief,and time for drainage to reduce jaundice),hospital stay,medical expenses,and QoL[Gastrointestinal Quality of Life Index(GIQLI)]were comparatively analyzed.Further,Logistic regression analysis was conducted to analyze factors influencing the QoL of patients with intra-and extrahepatic BDSs.RESULTS The data demonstrated a higher overall effective rate in the observation group compared to the control group(P=0.011),together with notably reduced OT,less IBL,shorter body temperature recovery time,pain relief time,time for drainage to reduce jaundice,and hospital stay(all P<0.05).The postoperative GIQLI of the observation group was more significantly increased compared to the control group(P<0.05).The two groups demonstrated no marked difference in medical expenses(P>0.05).CONCLUSION The above indicates that ERCP+EPBD+LH is effective in treating patients with intra-and extrahepatic BDSs,which is conducive to postoperative rehabilitation and QoL improvement,with promising prospects for clinical promotion.
文摘BACKGROUND Common bile duct stones pose a high risk of recurrence or disease progression if not promptly treated.However,there is still no optimal treatment approach.AIM To investigate the clinical efficacy of modified pancreatic duct stent drainage in endoscopic retrograde cholangiopancreatography(ERCP)for treating common bile duct stones.METHODS This retrospective study included 175 patients with common bile duct stones treated at Taizhou Fourth People’s Hospital between January 1,2021,and November 30,2023.The patients were divided into three groups-the modified pancreatic duct stent drainage group(59 cases),the nasobiliary drainage group(58 cases),and the standard biliary drainage group(58 cases).Preoperative general clinical data,laboratory indicators,and the visual analog scale(VAS)at two time points(24 hours before and after surgery)were compared,along with postoperative complications across the three groups.RESULTS Serum levels of aspartate aminotransferase,alanine aminotransferase,alkaline phosphatase,gamma-glutamyltransferase,total bilirubin,direct bilirubin,Creactive protein,and amylase were significantly lower in the modified pancreatic duct stent drainage group and the standard biliary drainage group than those in the nasobiliary drainage group(P<0.05).However,no statistically significant differences were observed in white blood cells,hemoglobin,or neutrophil levels among the three groups(P>0.05).The standard biliary drainage group had significantly lower VAS scores[(4.36±1.18)points]than those for the modified pancreatic duct stent drainage group[(4.92±1.68)points](P=0.033),and the nasobiliary drainage group[(5.54±1.24)points](P=0.017).There were no statistically significant differences in complication rates across the three groups(P>0.05).CONCLUSION Compared to standard biliary drainage and nasobiliary drainage,the modified pancreatic duct stent used during ERCP for patients with bile duct stones significantly reduced hepatocyte injury,improved liver function parameters,alleviated inflammation and pain,enhanced patient comfort,and demonstrated superior safety.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is associated with a variety of adverse events(AEs).One of the most important AEs is post-ERCP pancreatitis(PEP),which is most common in cases of difficult biliary cannulation.Although the precut technique has been reported as a PEP risk factor,recent studies indicate that early precut could reduce PEP,and that precut itself is not a risk factor.AIM To evaluate the safety of the precut technique,especially in terms of PEP.METHODS We conducted a retrospective study,spanning the period from November 2011 through December 2021.It included 1556 patients,aged≥20 years,who underwent their initial ERCP attempt for biliary disease with a naïve papilla at the Kawasaki University General Medical Center.We compared the PEP risk between the early precut and the delayed precut group.RESULTS The PEP incidence rate did not significantly differ between the precut and nonprecut groups.However,the PEP incidence was significantly lower in the early precut group than the delayed precut group(3.5%vs 10.5%;P=0.02).The PEP incidence in the delayed precut group without pancreatic stent insertion(17.3%)was significantly higher compared to other cases(P<0.01).CONCLUSION Our findings indicate that early precut may reduce PEP incidence.If the precut decision is delayed,a pancreatic stent should be inserted to prevent PEP.
文摘AIM: Prospective evaluation of repeat endoscopic retrograde cholangiopancreatography (ERCP) for failed Schutz grade 1 biliary cannulation in a high-volume center. METHODS: Prospective intention-to-treat analysis of patients referred for biliary cannulation following recent unsuccessful ERCP. RESULTS: Fifty-one patients (35 female; mean age: 62.5 years; age range: 40-87 years) with previous failed biliary cannulation were referred for repeat ERCP. The indication for ERCP was primarily choledocholithiasis (45%) or pancreatic malignancy (18%). Successful biliary can- nulation was 100%. The precut needle knife sphincterotomy (NKS) rate was 27.4%. Complications occurred in 3.9% (post-ERCP pancreatitis). An identif iable reason for initial unsuccessful biliary cannulation was present in 55% of cases. Compared to a cohort of 940 nave pa-pilla patients (female 61%; mean age: 59.9 years; age range: 18-94 years) who required sphincterotomy over the same time period, there was no statistical difference in the cannulation success rate (100% vs 98%) or postERCP pancreatitis (3.1% vs 3.9%). Precut NKS use was more frequent (27.4% vs 12.7%) (P = 0.017). CONCLUSION: Referral to a high-volume center following unsuccessful ERCP is associated with high technical success, with a favorable complication rate, compared to routine ERCP procedures.
文摘Background: Duodenoscope-related multidrug-resistant organism(MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 bleeding.Conclusions: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

文摘BACKGROUND Splenic injury following endoscopic retrograde cholangiopancreatography(ERCP)is a rare complication.The literature contains around 30 articles reporting various degrees of splenic injuries resulting from ERCP since the first report of splenic rupture after ERCP in 1989.CASE SUMMARY This report describes a case of splenic hematoma and stent displacement in a 69-year-old male patient who developed these conditions 7 days after undergoing ERCP and stenting.The patient had bile duct stenosis caused by a malignant tumor that was obstructing the bile duct.The diagnosis was confirmed by epigastric computed tomography and magnetic resonance cholangiopancreatography.The patient was successfully treated with percutaneous transhepatic cholangial drainage,endoscopic pyloric stent placement,and conservative management.The causes of splenic injury following ERCP are discussed.CONCLUSION ERCP has the potential to cause splenic injury.If a patient experiences symptoms such as abdominal pain,decreased blood pressure,and altered hematology after the procedure,it's important to be thoroughly investigated for postoperative bleeding and splenic injury.
文摘BACKGROUND Achromobacter xylosoxidans is a Gram-negative opportunistic aerobe,usually causing nosocomial infections in immunocompromised patients with manifestations including bacteremia,pneumonia,and catheter-related infections.However,A.xylosoxidans have not yet been reported to cause biliary system infections.CASE SUMMARY A 72-year-old woman presented to the outpatient department of our hospital with a chief complaint of jaundice.Computed tomography of her abdomen revealed the presence of a mass of approximately 2.4 cm in the hilar portion of the common hepatic duct,consistent with hilar cholangiocarcinoma.We performed endoscopic retrograde cholangiopancreatography(ERCP)to decompress the obstructed left and right intrahepatic ducts(IHDs)and placed 10 cm and 11 cm biliary stents in the left and right IHDs,respectively.However,the day after the procedure,the patient developed post-ERCP cholangitis as the length of the right IHD stent was insufficient for proper bile drainage.The blood culture of the patient tested positive for A.xylosoxidans.Management measures included the replacement of the right IHD stent(11 cm)with a longer one(12 cm)and administering culturedirected antibiotic therapy,solving the cholangitis-related complications.After the cholangitis had resolved,the patient underwent surgery for hilar cholangiocarcinoma and survived for 912 d without recurrence.CONCLUSION A.xylosoxidans-induced biliary system infections are extremely rare.Clinical awareness of physicians and endoscopists is required as this rare pathogen might cause infection after endoscopic procedures.
文摘BACKGROUND Traditional surgical procedures are highly invasive and risky for children with pancreatic and biliary diseases.Endoscopic retrograde cholangiopancreatography(ERCP)has been used mostly in adults because it is a safe and effective surgical procedure.Its application in children will contribute to the treatment and prog-nosis of children with pancreatic and biliary diseases.AIM To analyze the efficacy and safety of ERCP for the treatment of pediatric pancre-atobiliary diseases.METHODS A retrospective study was performed using the medical records of 101 pediatric patients who received treatment for pancreatobiliary diseases at Children’s Hospital Capital Institute of Pediatrics from April 2022 to April 2024.The patients were divided into an observation group(n=52,treated with ERCP)and a control group(n=49,treated with traditional surgical methods).Diagnostic and therapeutic outcomes of ERCP were statistically analyzed.Treatment efficacy,time to resume eating,and hospital stay duration were compared between the two groups.Indicators of liver function were monitored preoperatively and one week postoperatively.Dynamic changes in C-reactive protein(CRP)and serum amylase levels were assessed preoperatively and at 6 and 24 hours postoper-atively.Postoperative complications were also compared.Logistic multivariate regression was used to analyze the independent effect of ERCP on outcomes.RESULTS For the observation group,36 and 16 patients were diagnosed with biliary and pancreatic diseases,respectively.Compared with the control group,the observa-tion group exhibited a higher overall effective rate(P<0.05),shorter times to resume eating,shorter hospital stays(P<0.05),and significantly improved postoperative liver function(P<0.05).CRP and serum amylase levels were significantly increased in both groups at 6 and 24 hours postoperatively(P<0.05),but were significantly lower in the observation group(P<0.05).The observation group also had a lower incidence of complications(P<0.05).ERCP was an independent factor affecting treatment efficacy,length of hospital stay,total bilirubin,aspartate aminotransferase,and alanine aminotransferase,CRP,serum amylase,and the occurrence of complications in children with pancreaticobiliary diseases(P<0.05).CONCLUSION ERCP effectively enhances the treatment efficacy of pediatric pancreatobiliary diseases,with a reduced inflam-matory response,faster postoperative recovery,and fewer complications.ERCP is a safe and effective diagnostic and therapeutic method for pediatric pancreatobiliary diseases.

文摘In a recent issue of the World Journal of Gastrointestinal Surgery,a meta-analysis investigated the safety and efficacy of electrocautery-enhanced lumen-apposing metal stent(ECE-LAMS)implantation for managing malignant biliary obstruction following failed endoscopic retrograde cholangiopancreatography.This manusc-ript endeavors to offer a comprehensive look at the progression of endoscopic ultrasound-guided biliary drainage(EUS-BD)technologies,weighing their merits and drawbacks against traditional percutaneous methods.Several meta-analyses and randomized controlled trials have compared the performance of EUS-BD and percutaneous transhepatic cholangiodrainage(PTCD).These studies revealed that the technical success rate,clinical success rate,and adverse events were similar between EUS-BD and PTCD.Nevertheless,given that most of these studies preda-te 2015,the safety and effectiveness of novel EUS-BD techniques,including ECE-LAMS,compared with those of percutaneous biliary drainage remain elusive.Further investigation is imperative to ascertain whether these novel EUS-BD techniques can safely and efficaciously replace conventional percutaneous thera-peutic approaches.
文摘We comment on the article by Jia et al,in the World Journal of Gastrointestinal Surgery.We focus mainly on the factors that impair gastric motility and cause gastric retention in the pre-operative setting of endoscopic retrograde cholan-giopancreatography(ERCP).ERCP is a complex endoscopic therapeutic proce-dure,which demands great skill from the endoscopist but also has recognized complications.Gastric retention impairs the endoscopist’s visibility but also increases the risk of complications,such as aspiration pneumonia.Therefore,identifying the factors that predispose to gastric retention alerts the endoscopists of the possible risks and enables them to take evasive action.The authors in the current study by Jia et al developed and validated a predictive model,which in-corporates five different factors,i.e.,gender,primary disease,jaundice,opioid use,and gastrointestinal obstruction,which were found to influence gastric retention.This model was shown to have a high predictive value to accurately identify pa-tients at risk for gastric retention before a therapeutic ERCP.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is an essential therapeutic tool for biliary and pancreatic diseases.Frail and elderly patients,especially those aged≥90 years are generally considered a higher-risk population for ERCP-related complications.AIM To investigate outcomes of ERCP in the Non-agenarian population(≥90 years)concerning Frailty.METHODS This is a cohort study using the 2018-2020 National Readmission Database.Patients aged≥90 were identified who underwent ERCP,using the international classification of diseases-10 code with clinical modification.Johns Hopkins’s adjusted clinical groups frailty indicator was used to classify patients as frail and non-frail.The primary outcome was mortality,and the secondary outcomes were morbidity and the 30 d readmission rate related to ERCP.We used univariate and multivariate regression models for analysis.RESULTS A total of 9448 patients were admitted for any indications of ERCP.Frail and non-frail patients were 3445(36.46%)and 6003(63.53%)respectively.Indications for ERCP were Choledocholithiasis(74.84%),Biliary pancreatitis(9.19%),Pancreatico-biliary cancer(7.6%),Biliary stricture(4.84%),and Cholangitis(1.51%).Mortality rates were higher in frail group[adjusted odds ratio(aOR)=1.68,P=0.02].The Intra-procedural complications were insigni-ficant between the two groups which included bleeding(aOR=0.72,P=0.67),accidental punctures/lacerations(aOR=0.77,P=0.5),and mechanical ventilation rates(aOR=1.19,P=0.6).Post-ERCP complication rate was similar for bleeding(aOR=0.72,P=0.41)and post-ERCP pancreatitis(aOR=1.4,P=0.44).Frail patients had a longer length of stay(6.7 d vs 5.5 d)and higher mean total charges of hospitalization($78807 vs$71392)compared to controls(P<0.001).The 30 d all-cause readmission rates between frail and non-frail patients were similar(P=0.96).CONCLUSION There was a significantly higher mortality risk and healthcare burden amongst nonagenarian frail patients undergoing ERCP compared to non-frail.Larger studies are warranted to investigate and mitigate modifiable risk factors.
文摘BACKGROUND Portal vein injury is an uncommon complication of endoscopic retrograde cholangiopancreatography(ERCP),for which stent malpositioning in the portal vein is very rare and can lead to fatal events.We report a case of biliary stent migration to the portal vein and a novel method for its safe removal under the guidance of portal angiography.Moreover,we reviewed the literature and summarized reports on the identification and management of this condition.CASE SUMMARY A 59-year-old woman with pancreatic cancer presented with abdominal pain and a high fever 20 days after the placement of two plastic biliary stents under the guidance of ERCP.Blood cultures and laboratory tests revealed sepsis,which was treated with antibiotics.A contrast-enhanced computed tomography scan revealed that one of the biliary stents in the main portal vein was malpositioned.To safely remove the stent,portal angiography was performed to visualize the portal vein and to allow the management of any bleeding.The two stents were removed without obvious bleeding,and an uncovered self-expanding metal stent was placed in the common bile duct for drainage.The patient had an uneventful 6-month follow-up period,except for self-resolving portal vein thrombosis.CONCLUSION The combination of endoscopic and angiographic techniques allowed uneventful management of stent malposition in the portal vein.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is a key procedure for diagnosing and treating biliary and pancreatic disorders.Although effective,it carries risks,including rare but severe complications such as air embolism.CASE SUMMARY We report a case of a 58-year-old man who developed extensive air embolism during ERCP.He previously underwent a Whipple procedure and experienced a sudden drop in vital signs and loss of consciousness.Immediate intervention with hyperbaric oxygen therapy and supportive care led to gradual recovery.Imaging confirmed widespread air embolism,which resolved with continued treatment.CONCLUSION Air embolism is a rare,critical complication of ERCP,especially in patients with prior surgery such as pancreaticoduodenectomy.Early detection and prompt treatment,including hyperbaric oxygen therapy,are crucial for favorable out-comes.

文摘BACKGROUND Study on influencing factors of gastric retention before endoscopic retrograde cholangiopancreatography(ERCP)background:With the wide application of ERCP,the risk of preoperative gastric retention affects the smooth progress of the operation.The study found that female,biliary and pancreatic malignant tumor,digestive tract obstruction and other factors are closely related to gastric retention,so the establishment of predictive model is very important to reduce the risk of operation.METHODS A retrospective analysis was conducted on 190 patients admitted to our hospital for ERCP preparation between January 2020 and February 2024.Patient baseline clinical data were collected using an electronic medical record system.Patients were randomly matched in a 1:4 ratio with data from 190 patients during the same period to establish a validation group(n=38)and a modeling group(n=152).Patients in the modeling group were divided into the gastric retention group(n=52)and non-gastric retention group(n=100)based on whether gastric retention occurred preoperatively.General data of patients in the validation group and identify factors influencing preoperative gastric retention in ERCP patients.A predictive model for preoperative gastric retention in ERCP patients was constructed,and calibration curves were used for validation.The receiver operating characteristic(ROC)curve was analyzed to evaluate the predictive value of the model.RESULTS We found no statistically significant difference in general data between the validation group and modeling group(P>0.05).The comparison of age,body mass index,hypertension,and diabetes between the two groups showed no statistically significant difference(P>0.05).However,we noted statistically significant differences in gender,primary disease,jaundice,opioid use,and gastrointestinal obstruction between the two groups(P<0.05).Mul-tivariate logistic regression analysis showed that gender,primary disease,jaundice,opioid use,and gastrointestinal obstruction were independent factors influencing preoperative gastric retention in ERCP patients(P<0.05).The results of logistic regression analysis revealed that gender,primary disease,jaundice,opioid use,and gastroin-testinal obstruction were included in the predictive model for preoperative gastric retention in ERCP patients.The calibration curves in the training set and validation set showed a slope close to 1,indicating good consistency between the predicted risk and actual risk.The ROC analysis results showed that the area under the curve(AUC)of the predictive model for preoperative gastric retention in ERCP patients in the training set was 0.901 with a standard error of 0.023(95%CI:0.8264-0.9567),and the optimal cutoff value was 0.71,with a sensitivity of 87.5 and specificity of 84.2.In the validation set,the AUC of the predictive model was 0.842 with a standard error of 0.013(95%CI:0.8061-0.9216),and the optimal cutoff value was 0.56,with a sensitivity of 56.2 and specificity of 100.0.CONCLUSION Gender,primary disease,jaundice,opioid use,and gastrointestinal obstruction are factors influencing preoperative gastric retention in ERCP patients.A predictive model established based on these factors has high predictive value.
文摘Acute post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is a feared and potentially fatal complication that can be as high as up to 30%in high-risk patients.Pre-examination measures,during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events.Several studies have debated on the subject,however,numerous topics remain controversial,such as the effectiveness of prophylactic medications and the amylase dosage time.This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is a valuable therapeutic technique for pancreatobiliary diseases,and its application in the elderly is no longer limited.However,a higher incidence of procedure difficulty and periprocedural adverse events might be expected in elderly patients due to the presence of other medical disorders and the poor general condition of this population.AIM To evaluate the incidence,causes,and management of difficult biliary cannulation during ERCP in elderly patients and the role of difficult cannulation as a risk factor for adverse events.METHODS A total of 614 patients who underwent ERCP during the study period were prospectively studied and divided into two groups based on their age.One hundred and forty-six patients were aged 80 years or older and 468 patients were aged less than 80 years.The primary outcome measurements were cannulation difficulty,cannulation success rate,ERCP procedure time,and related adverse events.RESULTS There was no difference in the incidence of difficult cannulation among the two groups(32.9%vs 34.4%,P=0.765),as well as in the cannulation success rate(96.6%vs 96.8%,P=0.54).The cannulation techniques were shown to be safe and efficient in achieving successful cannulation.Logistic regression analysis showed that patients aged 80 years or older were not associated with increased adverse events;however,difficult cannulation cases[adjusted odds ratio(AOR)=3.478;95%confidence interval(CI):1.877-6.442;P<0.001]and patients with Charlson Comorbidity Index≥2(AOR=1.824;95%CI:0.993-3.349;P=0.045)were more likely to develop adverse events.In contrast,other factors including age≤65(AOR=3.460;95%CI:1.511-7.922;P=0.003),female gender(AOR=2.362;95%CI=1.089-5.124;P=0.030),difficult cannulation(AOR=4.527;95%CI:2.078-9.860;P<0.001),and patients with cholangitis(AOR=3.261;95%CI:1.204-8.832;P=0.020)were strongly associated with a higher rate of post-ERCP pancreatitis.CONCLUSION Advanced age has not been proved to be a risk factor for difficult cannulation,and secondary cannulation techniques can be safely and efficaciously utilized in this group.Patients with a Charlson Comorbidity Index≥2 and difficult cannulation are associated with an increased overall adverse events rate,while age≥80 years is not.
