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: 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 Endoscopic retrograde cholangiopancreatography(ERCP),with its clinical ad-vantages of less trauma and faster recovery,has become the primary treatment for choledocholithiasis.AIM To investigate the effects of different ERCP procedures on the sphincter of Oddi.METHODS The clinical data of 91 patients who underwent ERCP at Yixing Hospital of Traditional Chinese Medicine between February 2018 and February 2021 were analyzed retrospectively.The patients were divided into endoscopic sphinc-terotomy(EST,n=24)and endoscopic papillary balloon dilation(EPBD,n=67)groups.The duration of operation,pancreatic development,pancreatic sphinc-terotomy,intubation difficulties,stone recurrence,and incidence of reflux cho-langitis and cholecystitis were statistically analyzed in patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction in the EST and EPBD groups.RESULTS Differences in hypertension,diabetes,increased bilirubin,small diameter of the common bile duct,or ampullary diverticulum between the two groups were not significant.Statistically significant differences were observed between the two groups concerning sex and age(<60 years).Patients with a history of choledocholithiasis,pancreatitis,and Oddi sphincter dysfunction were higher in the EST group than in the EPBD group.The number of cases of pancreatic development,pancreatic duct sphincterotomy,and difficult intubation were higher in the EST group than in the EPBD group.The number of Oddi’s sphincter manometries,ERCP surgical outcomes,and guidewires entering the pancreatic duct several times in EST group were lower than those in the EPBD group.The numbers of stone recurrences,reflux cholangitis,and cholecystitis were higher in the EST group than in the EPBD group.CONCLUSION In summary,common bile duct stones,pancreatitis history,and multiple guided wire introductions into the pancreatic duct are independent risk factors for EST and EPBD.Based on this evidence,this study can provide actionable insights for clinicians and researchers.

文摘BACKGROUND Acute appendicitis is the most common abdominal emergency.At present,the main treatments for periappendiceal abscess include antibiotics and surgery.However,the complications and mortality of emergency surgery are high.The preferred therapy is conservative treatment with antibiotics first,ultrasound-guided puncture drainage or surgical treatment is followed when necessary.Endoscopic retrograde appendicitis therapy(ERAT)for acute uncomplicated appendicitis have been proved clinically effective,but it is rarely used in periap-pendiceal abscess.CASE SUMMARY We report a patient admitted to hospital because of“right lower abdominal pain for six days”.The computerized tomography(CT)of patient showed that appendicitis with fecaliths and abscess in the pelvis.The patient was treated by CT-guided puncture and drainage of abdominal abscess combined with ERAT to remove appendiceal fecaliths,irrigation and stent placement.CONCLUSION The patient did not receive surgery because of impoverished family.Abdominal pain did not recur during the follow-up period.This case confirms the value of ERAT in the treatment of periappendiceal abscess.
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 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 Acute pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography(ERCP).Currently,there is no suitable treatment for post-ERCP pancreatitis(PEP)prophylaxis.Few studies have prospectively evaluated interventions to prevent PEP in children.AIM To assess the efficacy and safety of the external use of mirabilite to prevent PEP in children.METHODS This multicenter,randomized controlled clinical trial enrolled patients with chronic pancreatitis scheduled for ERCP according to eligibility criteria.Patients were randomly divided into the external use of mirabilite group(external use of mirabilite in a bag on the projected abdominal area within 30 min before ERCP)and blank group.The primary outcome was the incidence of PEP.The secondary outcomes included the severity of PEP,abdominal pain scores,levels of serum inflammatory markers[tumor necrosis factor-alpha(TNF-α)and serum interleukin-10(IL-10)],and intestinal barrier function markers[diamine oxidase(DAO),D-lactic acid,and endotoxin].Additionally,the side effects of topical mirabilite were investigated.RESULTSA total of 234 patients were enrolled,including 117 in the external use of mirabilite group and theother 117 in the blank group.The pre-procedure and procedure-related factors were notsignificantly different between the two groups.The incidence of PEP in the external use ofmirabilite group was significantly lower than that in the blank group(7.7%vs 26.5%,P<0.001).The severity of PEP decreased in the mirabilite group(P=0.023).At 24 h after the procedure,thevisual analog scale score in the external use of mirabilite group was lower than that in the blankgroup(P=0.001).Compared with those in the blank group,the TNF-αexpressions weresignificantly lower and the IL-10 expressions were significantly higher at 24 h after the procedurein the external use of mirabilite group(P=0.032 and P=0.011,respectively).There were nosignificant differences in serum DAO,D-lactic acid,and endotoxin levels before and after ERCPbetween the two groups.No adverse effects of mirabilite were observed.CONCLUSIONExternal use of mirabilite reduced the PEP occurrence.It significantly alleviated post-proceduralpain and reduced inflammatory response.Our results favor the external use of mirabilite toprevent PEP in children.
文摘BACKGROUND It has been confirmed that three-dimensional(3D)imaging allows easier identification of bile duct anatomy and intraoperative guidance of endoscopic retrograde cholangiopancreatography(ERCP),which reduces the radiation dose and procedure time with improved safety.However,current 3D biliary imaging does not have good real-time fusion with intraoperative imaging,a process meant to overcome the influence of intraoperative respiratory motion and guide navigation.The present study explored the feasibility of real-time continuous image-guided ERCP.AIM To explore the feasibility of real-time continuous image-guided ERCP.METHODS We selected 23D-printed abdominal biliary tract models with different structures to simulate different patients.The ERCP environment was simulated for the biliary phantom experiment to create a navigation system,which was further tested in patients.In addition,based on the estimation of the patient’s respiratory motion,preoperative 3D biliary imaging from computed tomography of 18 patients with cholelithiasis was registered and fused in real-time with 2D fluoroscopic sequence generated by the C-arm unit during ERCP.RESULTS Continuous image-guided ERCP was applied in the biliary phantom with a registration error of 0.46 mm±0.13 mm and a tracking error of 0.64 mm±0.24mm.After estimating the respiratory motion,3D/2D registration accurately transformed preoperative 3D biliary images to each image in the X-ray image sequence in real-time in 18 patients,with an average fusion rate of 88%.CONCLUSION Continuous image-guided ERCP may be an effective approach to assist the operator and reduce the use of X-ray and contrast agents.
文摘BACKGROUND We aimed to investigate the effectiveness of endoscopic retrograde cholangiopan-creatography(ERCP)for treating obstructive jaundice(OJ)post hepatoblastoma(HB)surgery(post-HB OJ)by analyzing the data of a case and performing a literature review.CASE SUMMARY Clinical data of one patient with post-HB OJ treated by ERCP were retrospectively analyzed.Furthermore,clinical characteristics and insights into the diagnosis and treatment of post-HB OJ in children were summarized via searching various databases and platforms,such as China National Knowledge Infrastructure,Wanfang database,CQVIP database,PubMed,Ringer Link,and Google Scholar.The patient reported herein underwent five chemotherapy sessions after the diagnosis of HB and right hemihepatectomy after tumor size reduction;these were followed by two postoperative chemotherapy sessions.Three months postoperatively,the patient developed icteric sclera,strong tea-colored urine,and clay-like stools,and showed signs of skin itchiness;blood analysis showed significantly an increased conjugated bilirubin(CB)level(200.3μmol/L).Following the poor efficacy of anti-jaundice and hepatoprotective treatments,the patient underwent ERCP.Intraoperative imaging showed a dilated bile duct in the porta hepatis with significant distal stenosis.A 5 Fr nasopancreatic tube was placed in the dilated area through the stricture for external drainage,and the patient was extubated on postoperative day 6.Postoperatively,the patient’s stool turned yellow,and the CB level decreased to 78.2μmol/L.Fifteen days later,ERCP was repeated due to unrelieved jaundice symptoms,wherein a 7 Fr naso-biliary drainage tube was successfully placed.Three months post-ERCP,the jaundice symptoms resolved,and the CB level was reduced to 33.2μmol/L.A follow-up examination one year postoperatively revealed no jaundice symptoms and normal CB level.CONCLUSION Post-HB OJ is rare.Compared to biliary tract reconstruction,ERCP is less invasive and has a better therapeutic effect.

文摘BACKGROUND Pseudoaneurysms of the hepatic artery or its branches have been reported following abdominal trauma,iatrogenic injury at the time of many operations such as percutaneous transhepatic biliary drainage and cholecystectomy.Hepatic artery pseudoaneurysms after endoscopic retrograde cholangiopancreatography(ERCP)are uncommon and potentially life threatening and should be identified and treated rapidly.CASE SUMMARY We report a case of intra-abdominal hemorrhage secondary to a left hepatic artery pseudoaneurysm resulting from guide wire injury at ERCP.The patient primary diagnosis was acute biliary pancreatitis with cholangitis,he underwent ERCP on the third day of admission.During ERCP,the left intrahepatic bile duct was cannulated three times.Over the sixth day,Contrast enhanced computed tomography scan demonstrated left hepatic lobe contusion and a pseudoaneurysm formation.The patient was successfully treated with the embolization of a small branch of left hepatic artery angiographically.CONCLUSION The common complications of ERCP are pancreatitis,bleeding and perforation.False aneurysms occur as a result of damage to the wall of an artery.As far as we know,it is rare complication has been reported following ERCP.We advise urgent referral for angiographic embolization in this situation to avoid aneurysm rupture.
文摘BACKGROUND This study evaluated the safety and effectiveness of endoscopic retrograde cholangiopancreatography(ERCP)in pediatric patients with biliary and pancreatic diseases.A retrospective analysis was conducted on 57 ERCP procedures performed in 41 children,primarily for treating pancreatic diseases.The overall success rate was 91.2%,with no major complications observed.Post-ERCP pancreatitis(PEP)occurred in 8.8%of cases.Follow-up examinations over one year showed no recurrence of biliary or pancreatic diseases.Notably,endoscopic treatment led to a significant increase in body mass index(BMI).These findings demonstrate the valuable role of ERCP in managing such conditions.AIM To evaluate the safety and efficacy of ERCP for the management of biliary and pancreatic diseases in pediatric patients.METHODS We conducted a retrospective analysis of data from children aged 1-18 years who underwent ERCP for biliary and pancreatic diseases at Beijing Children’s Hospital between January 2021 and December 2022.The collected data included procedure time,endoscopic treatment,success rate,and postoperative complications.RESULTS Forty-one children underwent 57 ERCP procedures,including 14 with biliary duct disease and 27 with pancreatic disease.The mean age of the patients was 7.48±3.48 years.Biliary duct-related treatments were performed 18 times,and pancreatic disease treatments were performed 39 times.ERCP was primarily used to treat pediatric pancreatic diseases[68.4%(39/57)of the procedures].The overall success rate was 91.2%(52/57 patients).PEP was noted in five patients(8.8%,5/57),and no instances of bleeding,perforation,or cholangitis were observed.The patients were followed up for over one year,and no recurrence of biliary or pancreatic diseases was detected.Importantly,BMI significantly increased after endoscopic treatment compared to that before treatment(P=0.001).CONCLUSION The high success rate and lack of major complications support the valuable role of ERCP in the management of pediatric biliary and pancreatic diseases in the pediatric population.
文摘BACKGROUND Perforations(Perf)during endoscopic retrograde cholangiopancreatography(ERCP)are rare(<1%)but potentially fatal events(up to 20%mortality).Given its rarity,most data is through case series studies from centers or analysis of large databases.Although a meta-analysis has shown fewer adverse events as a composite(bleeding,pancreatitis,Perf)during ERCP performed at high-volume centers,there is very little real-world data on endoscopist and center procedural volumes,ERCP duration and complexity on the occurrence of Perf.AIM To study the profile of Perf related to ERCP by center and endoscopist procedure volume,ERCP time,and complexity from a national endoscopic repository.Patients from clinical outcomes research initiative-national endoscopic database(2000-2012)who underwent ERCP were stratified based on the endoscopist and center volume(quartiles),and total procedure duration and complexity grade of the ERCP based on procedure details.The effects of these variables on the Perf that occurred were studied.Continuous variables were compared between Perf and no perforations(NoPerf)using the Mann-Whitney U test as the data demonstrated significant skewness and kurtosis.RESULTS A total of 14153 ERCPs were performed by 258 endoscopists,with 20 reported Perf(0.14%)among 16 endoscopists.Mean patient age in years 61.6±14.8 vs 58.1±18.8(Perf vs.NoPerf,P=NS).The cannulation rate was 100%and 91.5%for Perf and NoPerf groups,respectively.13/20(65%)of endoscopists were high-volume performers in the 4th quartile,and 11/20(55%)of Perf occurred in centers with the highest volumes(4th quartile).Total procedure duration in minutes was 60.1±29.9 vs 40.33±23.5(Perf vs NoPerf,P<0.001).Fluoroscopy duration in minutes was 3.3±2.3 vs 3.3±2.6(Perf vs NoPerf P=NS).50%of the procedures were complex and greater than grade 1 difficulty.3/20(15%)patients had prior biliary surgery.13/20(65%)had sphincterotomies performed with stent insertion.Peritonitis occurred in only 1/20(0.5%).CONCLUSION Overall adverse events as a composite during ERCP are known to occur at a lower rate with higher volume endoscopists and centers.However,Perf studied from the national database show prolonged and more complex procedures performed by high-volume endoscopists at high-volume centers contribute to Perf.

文摘BACKGROUND Asparaginase(ASP)is an important drug in combined chemotherapy regimens for pediatric acute lymphoblastic leukemia(ALL);ASP-associated pancreatitis(AAP)is the main adverse reaction of ASP.Recurrent pancreatitis is a complication of AAP,for which medication is ineffective.AIM To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography(ERCP)in treating recurrent pancreatitis due to AAP.METHODS From May 2018 to August 2021,ten children(five males and five females;age range:4–13 years)with AAP were treated using ERCP due to recurrent pancreatitis.Clinical data of the ten children were collected,including their sex,age,weight,ALL risk grading,clinical symptoms at the onset of pancreatitis,time from the first pancreatitis onset to ERCP,ERCP operation status,and postoperative complications.The symptomatic relief,weight change,and number of pancreatitis onsets before and after ERCP were compared.RESULTS The preoperative symptoms were abdominal pain,vomiting,inability to eat,weight loss of 2-7 kg,and 2-9 pancreatitis onsets.After the operation,nine of ten patients did not develop pancreatitis,had no abdominal pain,could eat normally;the remaining patient developed three pancreatitis onsets due to the continuous administration of ASP,but eating was not affected.The postoperative weight gain was 1.5-8 kg.There was one case of post ERCP pancreatitis and two cases of postoperative infections;all recovered after medication.CONCLUSION ERCP improved clinical symptoms and reduced the incidence of pancreatitis,and was shown to be a safe and effective method for improving the management of recurrent pancreatitis due to AAP.
文摘Objective:To explore and analyze the application value of nursing intervention for patients with pancreatitis after endoscopic retrograde cholangiopancreatography(ERCP).Methods:From May 2022 to May 2023,100 patients with pancreatitis after ERCP who were admitted to the General Surgery Department of our hospital were selected as the research objects,they were divided into a research group and a general group by flipping coins,with 50 cases in each group.The research group received nursing intervention,and the general group received general nursing.The postoperative index recovery time,quality of life,and emotional performance were compared between the two groups.Results:The blood amylase recovery time,abdominal pain recovery time,white blood cell recovery time,and hospitalization time in the research group were significantly lower than those in the general group(P<0.05).Before intervention,the physical function,social factors,physiological performance,emotional state,and other quality of life indicators were compared between the groups,and there was no statistically significant difference(P>0.05);after intervention,the mentioned quality of life indicators were significantly better than that of the general group(P<0.05).Before intervention,the Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)scores between the groups were compared,and there was no statistically significant difference(P>0.05);after intervention,the SAS and SDS scores of the research group were significantly better than those of the general group(P<0.05).Conclusion:The application of nursing intervention in patients with pancreatitis after ERCP has high clinical value and specific practical significance.
文摘Background:To prevent stent migration during endoscopic ultrasound-guided hepaticogastrostomy(EUS-HGS),intra-scope channel release technique is important,but is unfamiliar to non-expert hands.The self-expandable metal stent(SEMS)is an additional factor to prevent stent migration.However,no compara-tive studies of laser-cut-type and braided-type during EUS-HGS have been reported.The aim of this study was to compare the distance between the intrahepatic bile duct and stomach wall after EUS-HGS among laser-cut-type and braided-type SEMS.Methods:To evaluate stent anchoring function,we measured the distance between the hepatic parenchyma and stomach wall before EUS-HGS,one day after EUS-HGS,and 7 days after EUS-HGS.Also,propensity score matching was performed to create a propensity score for using laser-cut-type group and braided-type group.Results:A total of 142 patients were enrolled in this study.Among them,24 patients underwent EUS-HGS using a laser-cut-type SEMS,and 118 patients underwent EUS-HGS using a braided-type SEMS.EUS-HGS using the laser-cut-type SEMS was mainly performed by non-expert endoscopists(n=21);EUS-HGS using braided-type SEMS was mainly performed by expert endoscopists(n=98).The distance after 1 day was significantly shorter in the laser-cut-type group than that in the braided-type group[2.00(1.70-3.75)vs.6.90(3.72-11.70)mm,P<0.001].In addition,this distance remained significantly shorter in the laser-cut-type group after 7 days.Although these results were similar after propensity score matching analysis,the distance between hepatic parenchyma and stomach after 7 days was increased by 4 mm compared with the distance after 1 day in the braided-type group.On the other hand,in the laser-cut-type group,the distance after 1 day and 7 days was almost the same.Conclusions:EUS-HGS using a laser-cut-type SEMS may be safe to prevent stent migration,even in non-expert hands.

文摘BACKGROUND During emergency endoscopic retrograde cholangiopancreatography(ERCP),the safety and feasibility of performing one-stage endoscopic treatment for patients with acute cholangitis(AC)due to choledocholithiasis are unclear.AIM To investigate the safety and feasibility of one-stage endoscopic treatment for moderate to severe AC.METHODS We enrolled all patients diagnosed with moderate to severe cholangitis due to common bile duct stones from January 2019 to July 2023.The outcomes were compared in this study between patients who underwent ERCP within 24 h and those who underwent ERCP 24 h later,employing a propensity score(PS)frame-work.Our primary outcomes were intensive care unit(ICU)admission rates,ICU length of stay,and duration of antibiotic use.RESULTS In total,we included 254 patients and categorized them into two groups based on the time elapsed between admission and intervention:The urgent group(≤24 h,n=102)and the elective group(>24 h,n=152).Ninety-three pairs of patients with similar characteristics were selected by PS matching.The urgent ERCP group had more ICU admissions(34.4%vs 21.5%,P=0.05),shorter ICU stays(3 d vs 9 d,P<0.001),fewer antibiotic use(6 d vs 9 d,P<0.001),and shorter hospital stays(9 d vs 18.5 d,P<0.001).There were no significant differences observed in adverse events,in-hospital mortality,recurrent cholangitis occurrence,30-d readmission rate or 30-d mortality.CONCLUSION Urgent one-stage ERCP provides the advantages of a shorter ICU stay,a shorter duration of antibiotic use,and a shorter hospital stay.
文摘BACKGROUND Infected acute necrotic collection(ANC)is a fatal complication of acute pancre-atitis with substantial morbidity and mortality.Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis;however,there is great controversy about the optimal drainage time,and better treatment should be explored.CASE SUMMARY We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancre-atitis;conservative treatment was ineffective,and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography(CT).Endoscopic ultra-sonography(EUS)suggested hyperechoic necrotic tissue within the cyst cavity.The wall was not completely mature,and the culture of the puncture fluid was positive for A-haemolytic Streptococcus.Thus,the final diagnosis of ANC in-fection was made.The necrotic collection was not walled off and contained many solid components;therefore,the patient underwent EUS-guided aspiration and lavage.Two weeks after the collection was completely encapsulated,pancreatic duct stent drainage via endoscopic retrograde cholangiopancreatography(ERCP)was performed,and the patient was subsequently successfully discharged.On repeat CT,the pancreatic cysts had almost disappeared during the 6-month fo-llow-up period after surgery.CONCLUSION Early EUS-guided aspiration and lavage combined with late ERCP catheter drainage may be effective methods for intervention in infected ANCs.
文摘Patients with malignant biliary obstruction,following endoscopic retrograde cholangiopancreatography(ERCP)failure could be referred for endoscopicultrasound-guided biliary drainage through electrocautery-enhanced(ECE)lumen-apposing metal stent(LAMS)placement.However,the efficacy and safety of ECE-LAMS in this scenario have remained debatable due to minimal scientific evidence.The current confirmed 91.0%clinical success,96.7%technical success,7.3%reintervention rate,and 17.5%adverse events,following the treatment of malignant biliary obstruction with ECE-LAMS delivery.Finally,ECE-LAMS proved to be a generalizable strategy for managing biliary obstruction for patients who were excluded from ERCP.
