Application Value of Nursing Intervention for Patients with Pancreatitis After Endoscopic Retrograde Cholangiopancreatography(ERCP)

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.

Left hepatic artery pseudoaneurysm complicating endoscopic retrograde cholangiopancreatography:A case report

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.

Pancreatic guidewire placement for achieving selective biliary cannulation during endoscopic retrograde cholangio-pancreatography

AIM: To investigate the frequency and risk factors for acute pancreatitis after pancreatic guidewire placement (P-GW) in achieving cannulation of the bile duct during endoscopic retrograde cholangio-pancreatography (ERCP). METHODS: P-GW was performed in 113 patients in whom cannulation of the bile duct was difficult. The success rate of biliary cannulation, the frequency and risk factors of post-ERCP pancreatitis, and the frequency of spontaneous migration of the pancreatic duct stent were investigated. RESULTS: Selective biliary cannulation with P-GW was achieved in 73% of the patients. Post-ERCP pancreatitis occurred in 12% (14 patients: mild, 13; moderate, 1). Prophylactic pancreatic stenting was attempted in 59% of the patients. Of the 64 patients who successfully underwent stent placement, three developed mild pancreatitis (4.7%). Of the 49 patients without stent placement, 11 developed pancreatitis (22%: mild, 10; moderate, 1). Of the five patients in whom stent placement was unsuccessful, two developed mild pancreatitis. Univariate and multivariate analyses revealed no pancreatic stenting to be the only significant risk factor for pancreatitis. Spontaneous migration of the stent was observed within two weeks in 92% of the patients who had undergone pancreatic duct stenting.CONCLUSION: P-GW is useful for achieving selective biliary cannulation. Pancreatic duct stenting after P-GW can reduce the incidence of post-ERCP pancreatitis, which requires evaluation by means of prospective randomized controlled trials.

Retrospective analysis of complications related to endoscopic retrograde cholangio-pancreatography in patients with cirrhosis vs patients without cirrhosis

BACKGROUND There is minimal objective data regarding adverse events related to endoscopic retrograde cholangio-pancreatography(ERCP)in patients with cirrhosis compared to those without cirrhosis and even fewer data comparing complications among cirrhosis patients based on severity of cirrhosis.AIM To determine if patients with cirrhosis are at increased risk of adverse events related to ERCP:mainly pancreatitis,bleeding,perforation,cholangitis,and mortality;And to see if higher Child-Pugh(CP)score and Model for End-Stage Liver Disease(MELD)score are associated with higher post-ERCP complications.METHODS We performed a retrospective analysis of 692 patients who underwent ERCP and analyzed the impact of cirrhosis etiology,gender,type of sedation used during procedure,interventions performed,and co-morbidities on the rate of complications in cirrhosis patients as compared to non-cirrhosis patients.RESULTS Overall complications were higher in those with cirrhosis as compared to those without cirrhosis(P=0.015 at significance level of 0.05).CP class,especially CP class C,was shown to be associated with a significantly higher rate of ERCP complications as compared to CP class A and CP class B(P=0.010 at significance level of 0.05).CONCLUSION The results of our study reaffirm that liver cirrhosis has an impact on the occurrence of complications during ERCP.Our study shows that CP class seems to be more reliable as compared to MELD score in predicting complications of ERCP in cirrhosis patients.

Carbon dioxide insufflation for endoscopic retrograde cholangiopancreatography:A meta-analysis and systematic review

AIM:To assess the safety and efficacy of carbon dioxide (CO2) insufflation during endoscopic retrograde cholangiopancreatography (ERCP). METHODS:The Cochrane Library, Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Science Citation Index Expanded, Chinese Biomedical Literature Database, and references in relevant publications were searched up to December 2011 to identify randomized controlled trials (RCTs) comparing CO2 insufflation with air insufflation during ERCP. The trials were included in the review irrespec-tive of sample size, publication status, or language. Study selection and data extraction were performed by two independent authors. The meta-analysis was performed using Review Manager 5.1.6. A random-effects model was used to analyze various outcomes.Sensitivity and subgroup analyses were performed if necessary. R ESULTS:Seven double-blind RCTs involving a total of 818 patients were identified that compared CO2 insufflation (n = 404) with air insufflation (n = 401) during ERCP. There were a total of 13 post-random- ization dropouts in four RCTs. Six RCTs had a high risk of bias and one had a low risk of bias. None of the RCTs reported any severe gas-related adverse events in either group. A meta-analysis of 5 RCTs (n = 459) indicated that patients in the CO2 insufflation group had less post-ERCP abdominal pain and distension for at least 1 h compared with patients in the air insuf-flation group. There were no significant differences in mild cardiopulmonary complications [risk ratio (RR) = 0.43, 95% CI:0.07-2.66, P = 0.36], cardiopulmonary (e.g., blood CO2 level) changes [standardized mean difference (SMD) = -0.97, 95% CI: -2.58-0.63, P = 0.23], cost analysis (mean difference = 3.14, 95% CI:-14.57-20.85, P = 0.73), and total procedure time (SMD = -0.05, 95% CI:-0.26-0.17, P = 0.67) between the two groups. C ONCLUSION:CO2 insufflation during ERCP appears to be safe and reduces post-ERCP abdominal pain and discomfort.

A phantom gallbladder on endoscopic retrograde cholangiopancreatography

Various complications have been related to laparoscopic cholecystectomy but most occur shortly after the procedure. In this report, we present a case with very late complications in which an abscess developed within the gallbladder fossa 6 years after laparoscopic cholecystectomy. The abscess resolved after treatment with CT-guided extrahepatic aspiration. However, 4 years later, an endoscopic retrograde cholangiopancreatography （ERCP） performed for choledocholithiasis demonstrated a “gallbladder” which communicated with the common bile duct via a patent cystic duct. This unique case indicates that a cystic duct stump may communicate with the gallbladder fossa many years following cholecystectomy.

Safety and Feasibility of Oral Rehydration Solution Prior to Endoscopic Retrograde Cholangiopancreatography

Purpose: The safety of oral rehydration therapy before endoscopic screening with respect to vital signs and complications after the screening procedure was assessed in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Methods: A total of 107 patients scheduled for ERCP were assigned to either the intravenous drip injection (DIV) group during fasting (56 patients) or ORS group given oral rehydration solution (51 patients) prior to endoscopy. Vital signs after ERCP, including blood pressure and temperature, blood biochemical data and the incidence of post-ERCP complications were compared between the groups. Results: No cases of aspiration pneumonia were detected in either groups. Moreover, there were no statistically significant differences between the DIV group and ORS group in terms of the biochemical data and vital signs after ERCP. The intergroup difference in the development of pancreatitis after ERCP was 2.3% [95% CI: ?5.7, 10.3], which was not statistically significant. Conclusions: The safety of oral rehydration therapy was found to be equivalent to that of the customary practice of infusion as a method for managing hydration and replenishing electrolytes in patients receiving ERCP. Oral rehydration therapy may be easily utilized as rehydration therapy prior to endoscopic screening for ERCP and other procedures.

Post-cholecystectomy iatrogenic bile duct injuries:Emerging role for endoscopic management

Post-cholecystectomy iatrogenic bile duct injuries(IBDIs),are not uncommon and although the frequency of IBDIs vary across the literature,the rates following the procedure of laparoscopic cholecystectomy are much higher than open cholecystectomy.These injuries caries a great burden on the patients,physicians and the health care systems and sometime are life-threatening.IBDIs are associated with different manifestations that are not limited to abdominal pain,bile leaks from the surgical drains,peritonitis with fever and sometimes jaundice.Such injuries if not witnessed during the surgery,can be diagnosed by combining clinical manifestations,biochemical tests and imaging techniques.Among such techniques abdominal US is usually the first choice while Magnetic Resonance Cholangio-Pancreatography seems the most appropriate.Surgical approach was the ideal approach for such cases,however the introduction of Endoscopic Retrograde Cholangio-Pancreatography(ERCP)was a paradigm shift in the management of such injuries due to accepted success rates,lower cost and lower rates of associated morbidity and mortality.However,the literature lacks consensus for the optimal timing of ERCP intervention in the management of IBDIs.ERCP management of IBDIs can be tailored according to the nature of the underlying injury.For the subgroup of patients with complete bile duct ligation and lost ductal continuity,transfer to surgery is indicated without delay.Those patients will not benefit from endoscopy and hence should not do unnecessary ERCP.For low–flow leaks e.g.gallbladder bed leaks,conservative management for 1-2 wk prior to ERCP is advised,in contrary to high-flow leaks e.g.cystic duct leaks and stricture lesions in whom early ERCP is encouraged.Sphincterotomy plus stenting is the ideal management line for cases of IBDIs.Interventional radiologic techniques are promising options especially for cases of failed endoscopic repair and also for cases with altered anatomy.Future studies will solve many unsolved issues in the management of IBDIs.

Is endoscopic papillary balloon dilatation really a risk factor for post-ERCP pancreatitis?

Endoscopic papillary balloon dilatation(EPBD) is useful for decreasing early complications of endoscopic retrograde cholangio-pancreatography(ERCP), including bleeding, biliary infection, and perforation, but it is generally avoided in Western countries because of a relatively high reported incidence of post-ERCP pancreatitis(PEP). However, as the efficacy of endoscopic papillary largeballoon dilatation(EPLBD) becomes widely recognized, EPBD is attracting attention. Here we investigate whether EPBD is truly a risk factor for PEP, and seek safer and more effective EPBD procedures by reviewing past studies. We reviewed thirteen randomised control trials comparing EPBD and endoscopic sphincterotomy(EST) and ten studies comparing direct EPLBD and EST. Three randomized controlled trials of EPBD showed significantly higher incidence of PEP than EST, but no study of EPLBD did. Careful analysis of these studies suggested that longer and higher-pressure inflation of balloons might decrease PEP incidence. The paradoxical result that EPBD with small-calibre balloons increases PEP incidence while EPLBD does not may be due to insufficient papillary dilatation in the former. Insufficient dilatation could cause the high incidence of PEP through the use of mechanical lithotripsy and stress on the papilla at the time of stone removal. Sufficient dilation of the papilla may be useful in preventing PEP.

Safety of high-carbohydrate fluid diet 2 h versus overnight fasting before non-emergency endoscopic retrograde cholangiopancreatography:A single-blind,multicenter,randomized controlled trial

Background:Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography(ERCP),the benefits and safety of high-carbohydrate fluid diet(CFD)intake 2 h before ERCP remain unclear.This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’recovery.Methods:This prospective,multicenter,randomized controlled trial involved 15 tertiary ERCP centers.A total of 1330 patients were randomized into CFD group(n=665)and fasting group(n=665).The CFD group received 400 mL of maltodextrin orally 2 h before ERCP,while the control group abstained from food/water overnight(>6 h)before ERCP.All ERCP procedures were performed using deep sedation with intravenous propofol.The investigators were blinded but not the patients.The primary outcomes included postoperative fatigue and abdominal pain score,and the secondary outcomes included complications and changes in metabolic indicators.The outcomes were analyzed according to a modified intention-to-treat principle.Results:The post-ERCP fatigue scores were significantly lower at 4 h(4.1±2.6 vs.4.8±2.8,t=4.23,P<0.001)and 20 h(2.4±2.1 vs.3.4±2.4,t=7.94,P<0.001)in the CFD group,with least-squares mean differences of 0.48(95%confidence interval[CI]:0.26-0.71,P<0.001)and 0.76(95%CI:0.57-0.95,P<0.001),respectively.The 4-h pain scores(2.1±1.7 vs.2.2±1.7,t=2.60,P=0.009,with a least-squares mean difference of 0.21[95%CI:0.05-0.37])and positive urine ketone levels(7.7%[39/509]vs.15.4%[82/533],χ^(2)=15.13,P<0.001)were lower in the CFD group.The CFD group had significantly less cholangitis(2.1%[13/634]vs.4.0%[26/658],χ^(2)=3.99,P=0.046)but not pancreatitis(5.5%[35/634]vs.6.5%[43/658],χ^(2)=0.59,P=0.444).Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla(odds ratio[OR]:0.61,95%CI:0.39-0.95,P=0.028)in the multivariable models.Conclusion:Ingesting 400 mL of CFD 2 h before ERCP is safe,with a reduction in post-ERCP fatigue,abdominal pain,and cholangitis during recovery.Trail Registration:ClinicalTrials.gov,No.NCT03075280.

Endoscopic management of complications of chronic pancreatitis

Pseudocysts and biliary obstructions will affect approximately one third of patients with chronic pancreatitis(CP).For CP-related,uncomplicated,pancreatic pseudocysts(PPC),endoscopy is the first-choice therapeutic option.Recent advances have focused on endosonography-guided PPC transmural drainage,which tends to replace the conventional,duodenoscope-based coma immediately approach.Ancillary material is being tested to facilitate the endosonography-guided procedure.In this review,the most adequate techniques depending on PPC characteristics are presented along with supporting evidence.For CP-related biliary obstructions,endoscopy and surgery are valid therapeutic options.Patient co-morbidities(e.g.,portal cavernoma)and expected patient compliance to repeat endoscopic procedures are important factors when selecting the most adapted option.Malignancy should be reasonably ruled out before embarking on the endoscopic treatment of presumed CP-related biliary strictures.In endoscopy,the gold standard technique consists of placing simultaneous,multiple,side-by-side,plastic stents for a oneyear period.Fully covered self-expandable metal stents are challenging this method and have provided 50%mid-term success.

Laparo-endoscopic “Rendezvous” to treat cholecysto-choledocolithiasis: Effective,safe and simplifies the endoscopist’s work

AIM: To investigate our clinical experience with combined laparo-endoscopic Rendezvous (RV) for the treatment of patients affected by gallstones and common bile duct (CBD) stones and especially to study the never evaluated opinion of the endoscopist concerning the difficulty of the intraoperative endoscopic procedure during the RV in comparison with standard endoscopic retrograde cholangio-pancreatography (ERCP). METHODS: Eighty consecutive patients affected by cholecystolithiasis and diagnosed or suspected CBD stones were treated with a standardized "tailored" RV. The relevant technical features, the feasibility, the effectiveness in stone clearance, the safety but also the simple evaluation of difficulty and agreement of the endoscopist were analyzed with a questionnaire. RESULTS: The feasibility was 97.5% and the effectiveness 100% concerning CBD clearance and solution of coexisting problems at the papilla. Minor morbidity was 3.3%, the operating time was prolonged by a mean of 14 min, the mean hospital stay was 3.8 d and only one stone’s recurrence occurred. The endoscopist evaluated the procedure to be simpler than standard ERCP-ES in 81.2% of the cases.CONCLUSION: Simultaneous RV carries higheffectiveness and safety at least comparable to those reported for other options. The endoscopist is very often satisfied with this approach because of the minimization of some steps of the endoscopic procedure and avoidance of relevant iatrogenic risk factors. If the mandatory collaboration between surgeons and endoscopists is guaranteed, this approach can often be preferable for the patient, the surgeon, the endoscopist and the hospital.

Endoscopic management of biliary complications after liver transplantation: An evidence-based review

Biliary tract diseases are the most common complications following liver transplantation(LT) and usually include biliary leaks, strictures, and stone disease. Compared to deceased donor liver transplantation in adults, living donor liver transplantation is plagued by a higher rate of biliary complications. These may be promoted by multiple risk factors related to recipient, graft, operative factors and post-operative course. Magnetic resonance cholangiopancreatography is the first-choice examination when a biliary complication is suspected following LT, in order to diagnose and to plan the optimal therapy; its limitations include a low sensitivity for the detection of biliary sludge. For treating anastomotic strictures, balloon dilatation complemented with the temporary placement of multiple simultaneous plastic stents has become the standard of care and results in stricture resolution with no relapse in > 90% of cases. Temporary placement of fully covered self-expanding metal stents(FCSEMSs) has not been demonstrated to be superior(except in a pilot randomized controlled trial that used a special design of FCSEMSs), mostly because of the high migration rate of current FCSEMSs models. The endoscopic approach of non-anastomotic strictures is technically more difficult than that of anastomotic strictures due to the intrahepatic and/or hilar location of strictures, and the results are less satisfactory. For treating biliary leaks, biliary sphincterotomy and transpapillary stenting is the standard approach and results in leak resolution in more than 85% of patients. Deep enteroscopy is a rapidly evolving technique that has allowed successful treatment of patients who were not previously amenable to endoscopic therapy. As a result, the percutaneous and surgical approaches are currently required in a minority of patients.

Endoscopic management of acute cholangitis in elderly patients

AIM: To evaluate clinical presentation, etiology, compli-cations and response to treatment in elderly patients with acute cholangitis.METHODS: Demographics, etiology of biliary obstruc-tion, clinical features, complications and associated systemic diseases of 175 patients with acute cholangitis were recorded. Endoscopic biliary drainage was performed using nasobiliary drain or stent. The complications related to ERCP, success of biliary drainage, morbidity, mortality and length of hospital stay were evaluated. RESULTS: Of 175 patients, 52 aged ≥ 60 years (groupⅠ, age < 60 years; group Ⅱ, age ≥ 60 years) and 105 were men. Fever was present in 38 of 52 patients of group Ⅱ compared to 120 of 123 in groupⅠ. High fever (fever ≥ 38.0℃) was more common in groupⅠ(118/120 vs 18/38). Hypotension (5/123 vs 13/52), altered sensorium (3/123 vs 19/52), peritonism (22/123 vs 14/52), renal failure (5/123 vs 14/52) and associated comorbid diseases (4/123 vs 21/52) were more common in group Ⅱ. Biliopancreatic malignancy was a common cause of biliary obstruction in group Ⅱ (n = 34) and benign diseases in groupⅠ(n = 120). Indications for biliary drainage were any one of the following either singly or in combination: a fever of ≥ 38.0℃ (n = 136), hypotension (n = 18), peritonism (n = 36), altered sensorium (n = 22), and failure to improve within 72 h of conservative management (n = 22). High grade fever was more common indication of biliary drainage in groupⅠand hypotension, altered sensorium, peritonism and failure to improve within 72 h of conservative management were more common indications in group Ⅱ. Endoscopic biliary drainage was achieved in 172 patients (nasobiliary drain: 56 groupⅠ, 24 group Ⅱ, stent: 64 groupⅠ, 28 group Ⅱ) without any significant age related difference in the success rate. Abdominalpain, fever, jaundice, hypotension, altered sensorium, peritonism and renal failure improved after median time of 5 d in 120 patients in groupⅠ(2-15 d) compared to 10 d in 47 patients of group Ⅱ (3-20 d). Normalization of leucocyte count was seen after a median time of 7 d (3-20 d) in 120 patients in groupⅠcompared to 15 d (5-26 d) in 47 patients in group Ⅱ. There were no ERCP related complications in either group. Five patients (carcinoma gallbladder n = 3, CBD stones n = 2) died in group Ⅱ and they had undergone biliary drainage after failure of response to conservative management for 72 h. There was a higher mortality in patients in group Ⅱ despite successful biliary drainage (0/120 vs 5 /52). Length of hospital stay was longer in group Ⅱ patients (16.4 ± 5.6, 7-30 d) than in groupⅠpatients (8.2 ± 2.4, 7-20 d).CONCLUSION: Elderly patients with acute cholangitis have a high incidence of severe cholangitis, concomitant medical illnesses, hypotension, altered sensorium, peritonism, renal failure and higher mortality even after successful biliary drainage.

胆管不均匀扩张与ERCP术后胰腺炎的关系

目的 探讨胆管不均匀扩张与ERCP术后胰腺炎的关系。方法 选择昆明医科大学第二附属医院2018年1月到2021年12月共247例因胆总管结石行内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatography,ERCP)+内镜下乳头括约肌切开术(endoscopic sphincterotomy,EST)+内镜下鼻胆管引流术(endoscopic nasobiliary drainage,ENBD)的患者,分扩张组(胆管直径≥10 mm)(A组=84)与无扩张组(胆管直径<10 mm)(B组=163,对照组)进行统计学处理并比较。结果 A组84例,其中女性45例;可疑的Oddi括约肌功能障碍(sphincter of oddi dysfunction,SOD)患者9例;困难插管者30例,其中插到胰管者22例,胰管显影者8例;胆胰管汇合异常(anomalous pancreaticobiliary ductal junction,APBDJ)者9例。A组患者中ERCP术后发生轻度胰腺炎10例,中度胰腺炎8例,重度胰腺炎3例。B组163例,其中女性72例;可疑的SOD患者11例;困难插管者63例,其中插到胰管者61例,胰管显影者2例;APBDJ患者1例。B组患者中ERCP术后发生轻度胰腺炎10例,中度胰腺炎1例,重度胰腺炎者4例。A组行吲哚美辛肛栓患者数为30例,B组为57例。A组ERCP术后胰腺炎(post-ERCP pancreatitis,PEP)发生率为25%,B组PEP发生率为9.20%,两者比较差异具有统计学意义(P=0.001);将247例患者整体进行Logistic单因素回归分析显示,胆管扩张(OR=3.289,95%CI=1.593~6.792,P=0.001)是PEP的独立危险因素。结论 女性患者且伴有胆管不均匀扩张患者(胆管直径≥10 mm)比无扩张患者(胆管直径<10 mm)在ERCP术后更容易患PEP。因此,在对这部分患者行ERCP+EST+ENBD手术时需谨慎处理,尽量避免行内镜下复杂的手术操作。

Role of endoscopic ultrasound during hospitalization for acute pancreatitis

Endoscopic ultrasound(EUS)is often used to detect the cause of acute pancreatitis(AP)after the acute attack has subsided.The limited data on its role during hospitalization for AP are reviewed here.The ability of EUS to visualize the pancreas and bile duct,the sonographic appearance of the pancreas,correlation of such appearance to clinical outcomes and the impact on AP management are analyzed from studies.The most important indication for EUS appears to be for detection of suspected common bile duct and/or gall bladder stones and microlithiasis.Such an approach might avoid diagnostic endoscopic retrograde cholangio-pancreatography with its known complications.The use of EUS during hospitalization for AP still appears to be infrequent but may become more frequent in future.

ERCP术后胰腺炎的危险因素及预防方法

内镜逆行胰胆管造影术(endoscopic retrograde cholangio⁃pancreatography,ERCP)是胆胰疾病诊断的主要操作技术之一。ERCP术后胰腺炎(post⁃ERCP pancreatitis,PEP)是ERCP术后最常见的并发症,延长病人的住院时间,重症胰腺炎甚至危及生命。了解PEP的危险因素对于预防PEP的发生至关重要。目前常见的PEP危险因素包括病人自身的和ERCP操作相关的。根据这些危险因素,予以相关的术前、术中、术后干预可有效降低PEP的发生率。本文总结阐述目前常见的PEP危险因素及预防方法,供广大临床工作者参考。

Endoscopic ultrasound guided biliary drainage

Endoscopic retrograde cholangio-pancreatography is the most appropriate technique for treating common bile duct and pancreatic duct stenosis secondary to benign and malignant diseases. Even if the procedure is performed by skillful endoscopist, there are patients in whom endoscopic stent placement is not possible. Common causes of failure include complex peripapillary diverticula, prior surgery procedures, tumor involvement of the papilla, biliary sphincter stenosis, and impacted stones. Percutaneous trans-hepatic biliary drainage (PTBD) and surgical intervention carry morbidity and mortality. Recently endoscopic ultrasonography-guided biliary drainage has been reported as an alternative technique. Endoscopic ultrasonography- guided biliary drainage using either direct access or a rendezvous technique has attracted attention as an alternative procedure to PTBD, with a technical success between 75%-100% and with low complication rate. We have reviewed published data on EUS guided biliary drainage procedures with the aim of summarizing the efficacy and safety of this promising method.
