Endoscopic retrograde cholangiopancreatography (ERCP) is an important tool for the diagnosis and treatment of the hepatobiliary system. The use of fluoroscopy to aid ERCP places both the patient and the endoscopy staff at risk of radiation-induced injury. Radiation dose to patients during ERCP depends on many factors, and the endoscopist cannot control some variables, such as patient size, procedure type, or fluoroscopic equipment used. Previous reports have demonstrated a linear relationship between radiation dose and fluoroscopy duration. When fluoroscopy is used to assist ERCP, the shortest fluoroscopy time possible is recommended. Pulsed fluoroscopy and monitoring the length of fluoroscopy have been suggested for an overall reduction in both radiation exposure and fluoroscopy times. Fluoroscopy time is shorter when ERCP is performed by an endoscopist who has many years experience of performing ERCP and carried out a large number of ERCPs in the preceding year. In general, radiation exposure is greater during therapeutic ERCP than during diagnostic ERCP. Factors associated with prolonged fluoroscopy have been delineated recently, but these have not been validated. 相似文献

AIM: To assess the efficacy of allopurinol to prevent hyperamylasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (PEP).
METHODS: One hundred and seventy patients were enrolled and randomized to two groups: a study group (n = 85) who received 300 mg of oral allopurinol at 15 h and 3 h before endoscopic retrograde cholangiopancreatography (ERCP) and a control group (n = 85) receiving an oral placebo at the same times. Main Outcome Measurements included serum amylase levels and the number severity of the episodes of pancreatitis. Serum amylase levels were classified as normal (〈 150 IU/L) or hyperamylasemia (〉 151 IU/L). Episodes of PEP were classified following Ranson's criteria and CT severity index.
RESULTS: Gender distribution was similar between groups. Mean age was 53.5 ±18.9 years for study group and 52.8 ± 19.8 years for controls. Also, the distribution of benign pathology was similar between groups. Hyperamylasemia was more common in the control group (P = 0.003). Mild PEP developed in two patients from the study group (2.3%) and eight (9.4%) from control group (P = 0.04), seven episodes were observed in high-risk patients of the control group (25%) and one in the allopurinol group (3.3%, P = 0.02). Risk factors for PEP were precut sphincterotomy (P = 0.02), pancreatic duct manipulation (P = 0.002) and multiple procedures (P = 0.000). There were no deaths or side effects.
CONCLUSION: Oral allopurinol before ERCP decreased the incidences of hyperamylasemia and pancreatitis in patients submitted to high-risk procedures. 相似文献

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. 相似文献

AIM:To retrospectively investigate the effect and safety of various new type precut sphincterotomy techniques (VNTPST) in endoscopic retrograde cholangiopancreato-graphy (ERCP) due to difficult biliary duct cannulation (DBC). METHODS:A plough-like pull-type sphincterotome (PLPTS) or improved short nose sphincterotome or improved needle knife was applied. VNTPST was carried out in 30 of 280 patients,whose biliary tract could not be exposed well or deep cannulation was difficult to perform during ERCP with traditional methods. Patients were followed up for short-term complications and the therapeutic effect of VNTPS was observed and compared with that of traditional endoscopic sphincterotomy (EST). RESULTS:A total 280 patients underwent ERCP,of which 3 failed in operation because of pathological features in stomch or duodenum,247 successfully underwent traditional ERCP (89.1%,247/277),30 failed (10.8%,30/277). VNTPS technique succeeded in 24 (80%,24/30) of 30 cases. The successful rate of deep biliary duct cannulation increased 8.6% (24/277),the total cannulation successful rate following precut was 97.7%. There was a significant difference between the two groups (97.7% vs 89.1%,χ2 = 17.1,P < 0.01). The incidence of complications was 9.3% (26/277) for traditional ERCP group and 13.3% (4/30) for VNTPS technique group. Guideline tip was broken in pancreatic duct (KPDGP) of one patient,and there was no pancreatitis,slight or moderate bleeding postoperatively occurred in 2 patients,1 patient had bleeding during operation (PDWN). There were no differences between VNTPS technique group and traditional ERCP (TRERCP)group (13.3% vs 9.3%,χ2 = 0.478,P > 0.05). CONCLUSION:VNTPS procedure and Deng's precut are highly effective methods to get biliary access during ERCP with DBC. With skillful techniques,it can increase the successful rate for deep cannulation of biliary duct and decrease complications. VNTPS technique,especially Deng's precut is as effective and safe as EST. This technique can be well performed in hospitals without particular equipments. 相似文献

Despite extensive research over the past 2 decades, effective prevention of post–endoscopic retrograde cholangiopancreatography pancreatitis (PEP) using pharmacologic agents has been elusive. Recently, research that is focused on nonsteroidal anti-inflammatory drugs has provided renewed hope by demonstrating that a medication can indeed prevent PEP. Today, based on high-quality clinical trial data, rectal nonsteroidal anti-inflammatory drugs can be recommended for preventing PEP in high-risk cases,and given the highly favorable risk and cost-benefit ratios, they should be considered for all patients undergoing endoscopic retrograde cholangiopancreatography. Ongoing research will define the optimal dose of rectal indomethacin and whether this medication can eliminate the need for prophylactic pancreatic stent placement in high-risk cases. Additional research is necessary to define the role of other promising pharmacologic agents in clinical practice. 相似文献

Background and Aims: Acute pancreatitis following endoscopic retrograde cholangiography presents a unique opportunity for prophylaxis and early modification of the disease process because the initial triggering event is temporally well defined and takes place in the hospital. We report a prospective, single-center, randomized, double-blind controlled trial to determine if rectal diclofenac reduces the incidence of pancreatitis following cholangiopancreatography.
Methods: Entry to the trial was restricted to patients who underwent endoscopic retrograde pancreatography. Immediately after endoscopy, patients were given a suppository containing either 100 mg diclofenac or placebo. Estimation of serum amylase level and clinical evaluation were performed in all patients.
Results: One hundred patients entered the trial, and 50 received rectal diclofenac. Fifteen patients developed pancreatitis (15%), of whom two received rectal diclofenac and 13 received placebo ( P < 0.01).
Conclusions: This trial shows that rectal diclofenac given immediately after endoscopic retrograde cholangiopancreatography can reduce the incidence of acute pancreatitis. 相似文献

Outcomes and timing of endoscopic retrograde cholangiopancreatography for acute biliary pancreatitis
《Digestive and liver disease》2019,51(9):1281-1286
BackgroundIndication of endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis (ABP) is challenging.AimsIn this retrospective study, we analyzed real-world data to understand the ERCP practice in ABP in Hungarian centers.MethodsClinical data on ABP patients (2013–2015) were extracted from our large multicentric database. Outcomes, quality indicators and the role of early timing of ERCP (<24 h from admission) were analyzed.ResultsThere were 356 patients with ABP. ERCP was performed in 267 (75%). Performance indicators of ERCP proved to be suboptimal with a biliary cannulation rate of 84%. Successful vs unsuccessful cannulation of naïve papilla resulted in lower rates of local [22.9% vs 40.9%, (P = 0.012)] and systemic [4.9% vs 13.6%, (P = 0.042)] complications. Successful vs unsuccessful clearance resulted in lower rates of local complications [22.5% vs 40.8%, (P = 0.008)]. Successful cannulation and drainage correlated with less severe course of ABP [3.6% vs 15.9%, (P = 0.001) and 4.1% vs 12.2%, (P = 0.033)] respectively. A tendency of an increased rate of local complications was observed if ERCP was performed later [<24 h: 21.1% (35/166); between 24–48 h: 23.4% (11/47); >48h: 37.2% (16/43) (P = 0.088)].ConclusionOptimization of ERCP indication in ABP patients is critical as suboptimal ERCP practices in ABP without definitive stone detection are associated with poorer clinical outcomes. 相似文献

Numerous endoscopic retrograde cholangiopancreatography (ERCP) techniques have been reported to achieve selective biliary cannulation success. For standard biliary cannulation procedures, the wire-guided cannulation technique has been reported to reduce the rate of post-ERCP pancreatitis (PEP) and increase the biliary cannulation success rate, although conflicting reports exist. The pancreatic or double-guidewire technique and several precut techniques have been reported as useful techniques in difficult biliary cannulation cases. Although ERCP is a useful endoscopic procedure, the risk of adverse events, particularly post-ERCP pancreatitis, is inevitable. Previous studies and analyses have revealed the risk factors for PEP. The efficacy of prophylactic pancreatic duct stent placement and the administration of rectal nonsteroidal anti-inflammatory drugs for preventing PEP has also been reported. Herein, we reviewed reports in the literature regarding the current status of selective biliary cannulation techniques and PEP prevention. 相似文献

AIM: To investigate the efficacy and safety profile of pancreatic duct (PD) stent placement for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).METHODS: We performed a search of MEDLINE, EMBASE, and Cochrane Library to identify randomized controlled clinical trials of prophylactic PD stent placement after ERCP. RevMan 5 software provided by Cochrane was used for the heterogeneity and efficacy analyses, and a meta-analysis was performed for the data that showed homogeneity. Categorical data are presented as relative risks and 95% confidence intervals (CIs), and measurement data are presented as weighted mean differences and 95%CIs.RESULTS: The incidence rates of severe pancreatitis, operation failure, complications and patient pain severity were analyzed. Data on pancreatitis incidence were reported in 14 of 15 trials. There was no significant heterogeneity between the trials (I2 = 0%, P = 0.93). In the stent group, 49 of the 1233 patients suffered from PEP, compared to 133 of the 1277 patients in the no-stent group. The results of this meta-analysis indicate that it may be possible to prevent PEP by placing a PD stent.CONCLUSION: PD stent placement can reduce postoperative hyperamylasemia and might be an effective and safe option to prevent PEP if the operation indications are well controlled. 相似文献

AIM To investigate the efficacy and safety of emergency endoscopic retrograde cholangiopancreatography(ERCP) in elderly patients with acute cholangitis. METHODS From June 2008 to May 2016, emergency ERCPs were performed in 207 cases of acute cholangitis at our institution. Patients were classified as elderly if they were aged 80 years and older(n = 102); controls were under the age of 80 years(n = 105). The patients' medical records were retrospectively reviewed for comorbidities, laboratory data, etiology of cholangitis(presence of biliary stones, biliary stricture and malignancy), details of the ERCP(therapeutic approaches, technical success rates, procedure duration), ERCP-related complications and mortality. RESULTS The frequency of comorbidities was higher in the elderly group than the control group(91.2% vs 67.6%). Periampullary diverticulum was observed in the elderly group at a higher frequency than the control group(24.5% vs 13.3%). Between the groups, there was no significant difference in the technical success rates(95.1% vs 95.2%) or endoscopicprocedure durations. With regard to the frequency of ERCP-related complications, there was no significant difference between the two groups(6.9% vs 6.7%), except for a lower rate of post-ERCP pancreatitis in the elderly group than in the control group(1.0% vs 3.8%). Neither angiographic nor surgical intervention was required in any of the cases with ERCP-related complications. There was no mortality during the observational periods. CONCLUSION Emergency ERCP for acute cholangitis can be performed safely even in elderly patients aged 80 years and older. 相似文献
