Objective?To assess the effectiveness and safety of diclofenac, one of the routine-used NSAIDs, in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). Methods Firstly, the electronic searches were conducted to retrieve Randomized controlled trials (RCTs) from The Cochrane Library, PubMed, Embase, OVID, CBM, CNKI, VIP and WanFang Data. Secondly, 12 kinds of specific Chinese journals like Chinese Journal of Gastroenterology and conference proceedings were hand-searched till June 2011, and all references in all included trials were searched, too. The RCTs on diclofenac for preventing PEP were identified and retrieved. The systematic review was conducted by using methods and principles recommended by the Cochrane Collaboration. Results A total of 5 RCTs involving 675 PEP patients were included. The Meta-analysis showed that diclofenac might reduce the incidence of PEP (OR=0.41, 95%CI 0.18 to 0.95, P=0.04), but the sensitivity analysis indicated this result was not stable. No evidence showed diclofenac could reduce the incidence of severe PEP (OR=0.40, 95%CI 0.08 to 2.06, P=0.27). And no adverse reactions related to the drug were reported. Conclusion Diclofenac may be safe and effective in reducing the incidence of PEP, but it has no significant effect on preventing severe PEP. Considering the methodological and scale limitation of included studies, this conclusion still needs to be proved by more large-scale and high-quality RCTs.
Objective To find the most effective treatment for a patient with difficult selective biliary cannulation (DSBC) during endoscopic retrograde cholangiopancreatography (ERCP) by EBM practice. Methods Evidence was retrieved from The Cochrane Library (Issue 1, 2010), ACP online, NGC (1998 to June 2010), PubMed (1950 to June 2010), and CBM (1994 to June 2010). The collected evidence was then graded. Results After preliminary research, we identified 18 relevant articles. The evidence showed that pre-cutting technique could increase cannulation success rates in DSBC and was safe, effective, and time-saving for an experienced endoscopist. Pancreatic duct occupation was easier to perform than pre-cutting technique and could also increase selective cannulation success rates in DSBC. According to the evidence, together with endoscopist’s experience and the preference of the patient and his family, needle-knife precut papillotomy was performed. Successful selective biliary cannulation was accomplished after pre-cutting. Conclusion The current evidence suggests that pre-cutting technique and pancreatic duct occupation could increase selective cannulation success rates in DSBC. Patients’ condition and endoscopist’s experience should be considered properly before the operation.
Objective To evaluate the effectiveness and safety of somatostatin and the analogue-octreotide in preventing post-ERCP pancreatitis. Methods We searched Cochrane Clinical Trial Register （Issue 1, April, 2004 ）, MEDLINE （1966- April, 2004）, EMBASE （1985- April, 2004）, CBM disc （1970- April, 2004） and The Clinical Trial Register of Chinese Evidence-Based Medicine Center and handsearched the related journals to identify Randomized Controlled Trials （RCT）of somatostatin and octreotide in post-endoscopic retrograde chnlangiopancreatography pancreatitis（PEP）prevention. Systematic review was conducted using the method recommended by The Cochrane Collaboration. Results Thirty-one trials involving 4 728 patients undergoing ERCP were included. Meta-analysis showed that the incidence of post-ERCP pancreatitis [ OR 0.33, 95% CI 0. 20 to 0. 54; P =0. 000 01 ; NNT =13] was significantly reduced by somatostatin. Octreotide could only reduce the incidence of hyperamylasemia [ OR 0. 54, 95% CI 0. 38 to 0. 77 ; P =0. 000 7 ]. The inci- dence of PEP, severe PEP and post-ERCP abdominal pain could not be reduced by octreotide. Conclusions Somatostatin can prevent post-ERCP pancreatitis. Four trials are of high quality in the 12 included studies and the results are consistent with the sensitive-analysis, so it is credible to some extent. However, existing evidence does not support that octreotide can reduce the incidence of PEP, so it is not recommended for this indication. Sensitive-analysis even showed that octreotide could increase the incidence of PEP. Therefore, whether it is necessary to carry out further clinical trials should be considered with caution.
Objective To evaluate the effectiveness and safety of pancreatic duct stenting in prevention of post-ERCP (endoscopic retrograde cholangiopancreatography) pancreatitis for patients at high risk. Methods We searched the Controlled Trials Database of the Cochrane Upper Gastro-Intestinal and Pancreatic Disease Group (Issue 1, 2004), Cochrane Controlled Trials Register (Issue 1, 2004), MEDLINE (1966-2004, 4), EMBASE (1985-2004, 4), CBMdisk (1970-2004, 4), and the Chinese Cochrane Center Database of Clinical Trials; we handsearched 8 Chinese journals, and references of eligible studies were also screened for inclusion. Randomized controlled trials on pancreatic stent for preventing post-endoscopic restrograde cholangiopancreatography pancreatitis (PEP) were identified.The systematic review was conducted using methods recommended by the Cochrane Collaboration. Results Six trials involving 468 high-risk patients for post-ERCP pancreatitis were included. The incidence of post-ERCP pancreatitis was significantly reduced by pancreatic duct stenting (Peto RR 0.31, 95% CI 0.19 to 0.52; P＜0.000 01; NNT=6). The incidence of severe PEP was also significantly lower in pancreatic duct stenting group compared with the control group (Peto OR 0.13, 95% CI 0.04 to 0.47; P=0.002; NNT=24). The results were consistent with the sensitivity-analysis when abstracts were excluded. Conclusion Pancreatic duct stenting appears to be an effective method to prevent PEP. Due to the limitation of the included trials and their methodology, the results should be considered with caution. High quality and large-scale trials are required.
ObjectiveTo explore how to select the suitable indications of ERCP for clinical diagnosis and treatment. MethodsThe data of patients treated by ERCP between January 2005 and December 2009 in our hospital were analyzed retrospectively. ResultsTotal 221 patients received ERCP, among whom 99 (45%) cases of common bile duct stones, 44 (20%) cases of malignant tumor, 9 (4%) cases of papilla narrow, 45 (20%) cases were negative, and 24 (11%) cases were failed. It had the trend that the number of the patients received ERCP reduced year by year. The postoperative complication rate was 11% (25 cases), including 15 cases of postoperative pancreatitis, 3 cases of bleeding, 5 cases of biliary duct infection, and 2 cases of basket stranded. ConclusionIn the modern medical condition, with the advancement of image and laparoscopy technology, we should select the diagnosis and treatment methods with the principles of no damage or less damage for patients, without unlimitedly broadening the clinical indications of ERCP.
Objective To explore and summarize the application of minimally invasive technique to every stage of severe acute pancreatitis (SAP). Methods The treatment of 101 SAP patients admitted to our hospital between January 1995 and December 2008 were retrospectively analyzed. After calculi were removed by endoscopic retrograde cholangiopancreatograpy (ERCP) and endoscopic sphincterotomy (EST), endoscopic nasobiliary drainage (ENBD) were applied, then rhubarb liquid was perfused into gut with a nutrient canal and ultrasound-guided abdominal drainage tube were simultaneously placed at the early stage. Some patients received continuous renal replacement therapy (CRRT) at the same time. Laparoscopic cholecystectomy (LC) was performed at the subacute stage, and choledochoscope was introduced to remove parapancreatic necrotic tissues at the late stage of SAP.Results Of all the 101 cases treated by the method mentioned above, 75 cases received ERCP (or EST) and ENBD, and 31 cases underwent rhubarb liquid perfusion with a nutrient canal. Eight cases underwent continuous renal replacement therapy (CRRT). Forty-eight cases underwent LC and ultrasoundguided abdominal drainage. Thirtysix cases with infected peripancreatic tissue or abscess underwent debridement under choledochoscope 3 to 14 times at the later stage. Five cases died of multiple organ failure (MOF) and acute respiratory distress syndrome (ARDS). The hemobilia ocurred in 2 patients during choledochoscopy and was cured under direct visualization by electric coagulation. Intestinal fistula happened in 3 cases and cured by drainage. Pancreatic pseudocyst was latterly seen in 3 cases and treated by the anastomosis of cyst with jejunum through selective operation. After the hospitalization of 9-132 d (mean 24 d), 96 cases completely recovered. Conclusion Timely application of minimally invasive technique to every stage of SAP can avoid the defects of traditional operations, decrease the injury and interference to the maximum, and raise the cure rate.
Objective To investigate clinical application and safety evaluation of sedative demulcent anesthesia in therapeutic endoscopic retrograde cholangiopancreatography (ERCP).Methods Totally 1660 patients underwent ERCP at the First Hospital of Lanzhou University were prospectively divided into two groups: venous sedative demulcent group (n=800, using sufentanil and midazolam and propofol continuing infusion) and conventional sedative demulcent group (n=860, using common medicine). The heart rate (HR), respiration (R), blood pressure (BP) and peripheral oxygen saturation (SpO2) of pre-anesthesia, post-anesthesia, during operation and after analepsia in every group were detected. The narcotism was evaluated by Ramsaymin grading method and the related adverse reactions such as cough, restlessness, harmful memory, and abdominal pain after operation were recorded. Results Compared with conventional sedative demulcent group, vital signs of patients in venous sedative demulcent group were more stable. For postoperative adverse reactions, abdominal pain, abdominal distension and nausea and vomiting were respectively 4.4%(35/800), 2.6%(21/800) and 3.6%(29/800) in venous sedative demulcent group, which were respectively higher of the incidence of 36.3%(312/860), 49.0%(421/860) and 53.0%(456/860) in conventional sedative demulcent group (P＜0.01). The postoperative satisfaction and adverse reactions recall between venous sedative demulcent group and conventional sedative demulcent group was respectively significant different (96.9% vs. 2.9%, 4.8% vs. 97.9%, P＜0.01). Conclusion Sufentanil and midazolam and propofol continuing infusion have good effect of sedative demulcent anesthesia, which can be widely used.
ObjectiveTo compare clinical effect of biliary metallic stent implantation via endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangial drainage (PTCD) approaches in treatment of malignant obstructive jaundice. MethodsOne hundred and thirty-six patients with malignant obstructive jaundice who received the biliary metallic stent implantation from June 2010 to June 2015 in this hospital were selected. There were 53 cases via ERCP approach (ERCP group), in which 44 patients with low malignant obstructive jaundice, 9 patients with high malignant obstructive jaundice. There were 83 cases via PTCD approach (PTCD group), in which 24 patients with low malignant obstructive jaundice, 59 patients with malignant obstructive jaundice. The surgical success rate, effective rate, incidence of postoperative complications, hospital stay, and hospitalization expenses were compared in these two groups. Results① The total surgical success rate had no significant difference between the ERCP group and the PTCD group (P > 0.05). The surgical success rate of the patients with low malignant obstructive jaundice had no significant difference between the ERCP group and PTCD group (P > 0.05), which of the patients with high malignant obstructive jaundice in the ERCP group was significantly lower than that in the PTCD group (P < 0.05). ② The total effective rate had no significant difference between the ERCP group and PTCD group (P > 0.05), which of the patients with low malignant obstructive jaundice in the ERCP group was significantly higher than that in the PTCD group (P < 0.05), which of the patients with high malignant obstructive jaundice in the ERCP group was significantly lower than that in the PTCD group (P < 0.05). ③ The hospital stay of the ERCP group was significantly shorter than that in the PTCD group (P < 0.05). The hospitalization expenses had no significant difference between the ERCP group and PTCD group (P > 0.05). ④ The total incidence of complications in the ERCP group was significantly lower than that in the PTCD group (P < 0.05), which of the patients with low malignant obstructive jaundice in the ERCP group was significantly lower than that in the PTCD group (P < 0.05), which of the patients with high malignant obstructive jaundice in the ERCP group was significantly higher than that in the PTCD group (P < 0.05). ConclusionsThe biliary metallic stent implantation via ERCP and PTCD approaches in treatment of malignant obstructive jaundice could all obtain a better clinical efficacy. It has more advantages in patients with low malignant obstructive jaundice via ERCP approach and in the patients with high malignant obstructive jaundice via PTCD approach.
Objective To compare the difference in efficacy of early precut of pancreatic duct sphincter and pancreatic duct stent placement in the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) during high-risk patients. Methods A prospective study was conducted on 61 eligible patients who underwent ERCP treatment in Department of Hepatobiliary Surgery of The First Affiliated Hospital of Xi’an Jiaotong University and Xianyang Hospital of Yan’an University, from November 2016 to November 2017. All cases were randomly divided into early pancreatic sphincterotomy group (n=30) and pancreatic duct stenting group (n=31) . The success rate of intubation, intubation, and incidence of complication were compared. Results There was no significant difference in the success rate of the first intubation between the 2 groups (P=0.580), but the intubation time of the early pancreatic sphincterotomy group was shorter than that of the pancreatic duct stenting group (P=0.007). In the early pancreatic sphincterotomy group, there was 1 case of post-ERCP pancreatitis, 1 case of biliary tract infection, and 1 case of postoperative bleeding. In the pancreatic duct stenting group, there was 1 case of post-ERCP pancreatitis, and 2 cases of biliary tract infection. No severe complications such as perforation or severe acute pancreatitis occurred in both 2 groups. There was no significant difference in the incidence of total complications and specified complication (included post-ERCP pancreatitis, biliary tract infection, and postoperative bleeding) between the 2 groups (P>0.05). Conclusions Thereis no significant difference in the incidence of postoperative pancreatitis after early precut of pancreatic duct sphincter and pancreatic duct stenting placement in patients with high-risk, but intubation time of early precut of pancreatic duct sphincter method is shorter than the pancreatic duct stenting placement method.
