Steerable catheter based on wire-driven seamless artificial blood vessel tube for endoscopic retrograde transpapillary interventions. Int J Comput Assist Radiol Surg 2023; 18:433-447. [PMID: 36477583 DOI: 10.1007/s11548-022-02805-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Accepted: 11/22/2022] [Indexed: 12/13/2022]
Abstract
PURPOSE Current steerable catheters (SCs) for endoscopic retrograde cholangiopancreatography (ERCP) have performance limitations caused by an asymmetric multiple-slit tube design with a small maximum bend angle, lesser curvatures, and insufficient durability. We propose a wire-driven SC for balanced bidirectional bending using artificial blood vessel material to overcome these limitations. We assess the SC prototype's steerability using phantom and animal models. METHODS The SC prototype employed a slit-less and multiple-lumen seamless tube with a polytetrafluoroethylene (PTFE) body with stretch-retractable porous expanded PTFE at the distal end, and loop-formed control wires. We evaluated the wire routing design using a static model. The bending performance was compared with conventional SCs. Feasibility studies were performed, including major duodenal papilla insertions and ductal branch selections in desktop phantoms and a mini-pig model. RESULTS The proposed design reduced the wire contact force by 48% compared to the single wire configuration. The maximum bend angle was 162°, almost twofold larger than that for conventional SCs. The lateral tip position in the bent shape was maximally 56% smaller. The tip flexibility was comparable to conventional SCs, and the insertion resistance was similar to the passive catheters. Phantom studies showed that the SC prototype could perform the large and protuberant papilla insertions and fine ductal branch selections without breaking; the animal study was completed successfully. CONCLUSION We propose a wire-driven SC design for ERCP using a multi-lumen seamless tube and two loop-formed control wires, different from the conventional SC design with a multiple-slit tube and single control wire. The SC prototype records balanced bidirectional bending with a maximum bending angle of ± 162° without breakage risk. The phantom and animal studies show that the prototype performance potentially facilitates papilla cannulations and intrahepatic ductal branch seeking.

Radiocontrast agent and intraductal pressure promote the progression of post-ERCP pancreatitis by regulating inflammatory response, cellular apoptosis, and tight junction integrity. Pancreatology 2022; 22:74-82. [PMID: 34810073 DOI: 10.1016/j.pan.2021.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 10/19/2021] [Accepted: 11/03/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication following ERCP and the mechanism is not fully understood. This study evaluated the changes in the inflammatory response, cellular apoptosis, and tight junction integrity in a rat model of pancreatitis to explore the underlying mechanism. METHODS PEP was induced in rats by retrograde biliopancreatic ductal infusion of contrast agents or saline. Pancreatic tissues were harvested and evaluated by histopathologic, immunohistochemical, immunofluorescence, and Western blot analyses. In addition, amylase and proinflammatory cytokines in plasma were quantified by ELISA assay. RESULTS PEP rats developed more severe acute pancreatitis than the sham group after injection of the contrast agent or isotonic saline. PEP rats exhibited increased tissue damage, plasma amylase, proinflammatory cytokines, necrosis, inflammatory infiltrates, apoptosis, and tight junction disruption. At the molecular level, contrast agent and isotonic saline-injected PEP rats demonstrated elevated NF-κB p65 and STAT3 pathways activation, altered expression and activation of apoptosis-related proteins, and suppressed expression of tight junction molecules. However, the contrast agent concentration had no effect on these changes. CONCLUSIONS In models of acute pancreatitis induced using contrast agent and hydrostatic pressure, the contrast agent and high hydrostatic pressure easily induced the inflammatory response, apoptosis, and tight junction disruption. It is noteworthy that no significant difference in damaged pancreatic acinar cells was observed with different concentrations of the contrast agent.

Abstract
Postprocedural complications encompass a wide array of conditions that vary in acuity, symptoms, index procedure, and treatment. Continued advancements in diagnostic and therapeutic procedures have led to a significant shift of procedures to the ambulatory setting. This trend is of particular interest to the emergency physician, as patients who develop complications often present to an emergency department for evaluation and treatment. Here the authors examine a high-yield collection of procedures, both ambulatory and inpatient, notable for their frequent utilization and unique complication profiles including common laparoscopic surgical procedures, bariatric surgery, endoscopic procedures, interventional radiology procedures, and hernia repairs with implantable mesh.

Abstract
Cholelithiasis is a common gastrointestinal pathology with a prevalence of over 6% in the USA. Symptomatic patients can develop cholangitis, biliary colic, pancreatitis and cholecystitis. Surgical management involves laparoscopic or open cholecystectomy. Stones within the common bile duct can be treated with endoscopic retrograde cholangiopancreatography (ERCP). Well-known ERCP complications include pancreatitis, perforation, bleeding and cholangitis. Hepatic hematomas as a complication of ERCP are extremely rare, with fewer than 50 reported cases in the literature. Approximately 22% have required operative management. We present an extremely rare case of ERCP-associated subcapsular hepatic hematoma in a 43-year-old lady that was initially non-operatively managed. She did not improve with antibiotics alone and underwent attempted interventional radiology drainage. Despite this, due to on-going sepsis, the patient underwent laparoscopic necrosectomy and drain placement with continued post-operative irrigation. After a long course of antibiotics and drain irrigation, the patient was discharged with repeated computed tomography imaging showing almost total resolution of the infected collection. This case highlights the extreme rarity of surgical management for post-ERCP subcapsular hepatic hematoma and its successful outcome.

Abstract
INTRODUCTION Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most frequently performed minimally invasive procedures currently available for diagnosis and treatment of biliary and pancreatic diseases. Though considered a safe procedure, it has the highest rate of complications among the other endoscopic procedures, such as duodenal perforation and hepatic subcapsular hematoma (HSH). We are a presenting a case report and review of the current literature. METHOD We report one case HSH rupture, in a 25 years old female patient, 15 cm in diameter, affecting liver segments VI, VII and VIII, who underwent surgical treatment and performed a systematic literature review with the descriptors: endoscopic retrograde colangiopancreatography and hepatic subcapsular hematoma. All articles were reviewed and data on cases that presented rupture of the HSH analyzed separately. RESULTS Sixty one cases of HSH were described in the literature, fourteen of them ruptured. When analyzing only the subgroup of patients who had ruptured subcapsular hematoma, we showed a significant increase in the mortality rate of patients when compared to non-ruptured (21.4% × 2.2%). We also report that patients with rupture required some type of intervention, of which 78.6% required surgery. Conservative treatment may be the conduct and will suffice for most cases of non-ruptured hematomas. For patients who evolve with rupturing, surgical resolution, although non-mandatory, is necessary in most cases. CONCLUSION HSH ruptured is a rare and potentially fatal post-ERCP complication whose treatment is eminently surgical.

Abstract
BACKGROUND Post endoscopic retrograde cholangiopancreatography (ERCP) is comparatively complex application. Researchers has been investigated prevention of post-ERCP pancreatitis (PEP), since it has been considered to be the most common complication of ERCP. Although ERCP can lead various complications, it can also be avoided.
AIM To study the published evidence and systematically review the literature on the prevention and treatment for PEP.
METHODS A systematic literature review on the prevention of PEP was conducted using the electronic databases of ISI Web of Science, PubMed and Cochrane Library for relevant articles. The electronic search for the review was performed by using the search terms “Post endoscopic retrograde cholangiopancreatography pancreatitis” AND “prevention” through different criteria. The search was restricted to randomized controlled trials (RCTs) performed between January 2009 and February 2019. Duplicate studies were detected by using EndNote and deleted by the author. PRISMA checklist and flow diagram were adopted for evaluation and reporting. The reference lists of the selected papers were also scanned to find other relevant studies.
RESULTS 726 studies meeting the search criteria and 4 relevant articles found in the edited books about ERCP were identified. Duplicates and irrelevant studies were excluded by screening titles and abstracts and assessing full texts. 54 studies were evaluated for full text review. Prevention methods were categorized into three groups as (1) assessment of patient related factors; (2) pharmacoprevention; and (3) procedural techniques for prevention. Most of studies in the literature showed that young age, female gender, absence of chronic pancreatitis, suspected Sphincter of Oddi dysfunction, recurrent pancreatitis and history of previous PEP played a crucial role in posing high risks for PEP. 37 studies designed to assess the impact of 24 different pharmacologic agents to reduce the development of PEP delivered through various administration methods were reviewed. Nonsteroidal anti-inflammatory drugs are widely used to reduce risks for PEP. Rectal administration of indomethacin immediately prior to or after ERCP in all patients is recommended by European Society for Gastrointestinal Endoscopy guidelines to prevent the development of PEP. The majority of the studies reviewed revealed that rectally administered indomethacin had efficacy to prevent PEP. Results of the other studies on the other pharmacological interventions had both controversial and promising results. Thirteen studies conducted to evaluate the efficacy of 4 distinct procedural techniques to prevent the development of PEP were reviewed. Pancreatic Stent Placement has been frequently used in this sense and has potent and promising benefits in the prevention of PEP. Studies on the other procedural techniques have had inconsistent results.
CONCLUSION Prevention of PEP involves multifactorial aspects, including assessment of patients with high risk factors for alternative therapeutic and diagnostic techniques, administration of pharmacological agents and procedural techniques with highly precise results in the literature.

Abstract
AIM To assess incidence of post-endoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis in the early (July/August/September) vs the late (April/May/June) academic year and evaluate in-hospital mortality, length of stay (LOS), and total hospitalization charge between these time periods.
METHODS This was a retrospective cohort study using the 2012 Nationwide Inpatient Sample (NIS). Patients with International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) procedure codes for ERCP were included. Patients were excluded from the study if they had an ICD-9 CM code for a principal diagnosis of acute pancreatitis, if the ERCP was performed before or on the day of admission or if they were admitted to non-teaching hospitals. Post-ERCP pancreatitis was defined as an ICD-9 CM code for a secondary diagnosis of acute pancreatitis in patients who received an ERCP as delineated above. ERCPs performed during the months of July, August and September was compared to those performed in April, May and June in academic hospitals. ERCPs performed at academic hospitals during the early vs late year were compared. Primary outcome was incidence of post-ERCP pancreatitis. Secondary outcomes included in-hospital mortality, length LOS, and total hospitalization charge. Proportions were compared using fisher’s exact test and continuous variables using student t-test. Multivariable regression was performed.
RESULTS From the 36480032 hospitalizations in 2012 in the United States, 6248 were included in the study (3065 in July/August/September and 3183 in April/May/June) in the 2012 academic year. Compared with patients admitted in July/August/September, patients admitted in April/May/June had no statistical difference in all variables including mean age, percent female, Charleston comorbidity index, race, median income, and hospital characteristics including region, bed size, and location. Incidence of post-ERCP pancreatitis in early vs late academic year were not statistically significant (OR = 1.03, 95%CI: 0.71-1.51, P = 0.415). Similarly, the adjusted odds ratio of mortality, LOS, and total hospitalization charge in early compared to late academic year were not statistically significant.
CONCLUSION Incidence of post-ERCP pancreatitis does not differ at academic institutions depending on the time of year. Similarly, mortality, LOS, and total hospital charge do not demonstrate the existence of a temporal effect, suggesting that trainee level of experience does not impact clinical outcomes in patients undergoing ERCP.

Abstract
Sub capsular hepatic haematoma is a rare complication after endoscopic retrograde cholangiopancreatography (ERCP). Exact pathological mechanism is still unclear and few reports are nowadays available in literature. We report the case of a 58-year-old woman with recurrent episodes of upper abdominal pain, nausea and vomiting. On the basis of laboratory exams, abdomen ultrasound and magnetic resonance imaging she was diagnosed with a common bile duct stone. Endoscopic biliary sphincterotomy was performed. On the following day the patient complaint severe abdominal pain with rebound and hemodynamic instability. A computed tomography scan reveal a 14 cm × 6 cm × 19 cm sub-capsular hepatic haematoma on the right lobe that was successfully managed via percutaneous embolization. Sub capsular liver haematoma is a rare life threatening complication after ERCP that should be managed according to patients’ haemodynamic and clinic.

Abstract
Background. Endoscopic retrograde cholangiopancreatography (ERCP) is an established treatment modality for bile duct disorders, but patients have a risk of post-ERCP pancreatitis (PEP) and biliary sepsis. Aim. To evaluate the effectiveness and safety of pancreatic stent for prophylaxis of PEP and biliary sepsis in high-risk patients with complicating common bile duct (CBD) disorders. Methods. Two hundred and six patients with complicating confirmed or suspected CBD disorders were randomly assigned to receive ERCP with pancreatic stenting (experimental group) or without stenting (control group). Primary outcome measure was frequency of PEP, and secondary outcome measures included operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities. Results. Baseline age, sex, CBD etiology, concomitant medical/surgical conditions, cannulation difficulty, and ERCP success were comparable between the two groups (all P > 0.05). Compared to the control group, the experimental group had a significantly lower frequency of PEP (7.7% versus 17.7%, P < 0.05) and positive bile microbial culture (40.4% versus 62.7%, P < 0.05). However, the two groups were similar in operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities (all P > 0.05). Conclusions. Pancreatic stenting can reduce the occurrence of PEP and biliary sepsis in high-risk patients with complicating CBD disorders but does not increase other ERCP-associated morbidities. This trial is registered with the Chinese Clinical Trial Registry (registration identifier ChiCTR-OCH-14005134).

Abstract
BACKGROUND AND AIM Pancreatitis is the most common and serious complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Prevention strategies targeting risk factors could be important to reduce the rate of post-ERCP pancreatitis. However, the risk factors for post-ERCP pancreatitis (PEP) are still debated. This systematic review and meta-analysis was performed to identify risk factors for PEP. METHODS Medline (PubMed and Ovid), Cochrane Central Register of Controlled trials & Database of Systematic Reviews, Embase, Scopus, ScienceDirect, Springer links and WEB OF SCIENCE were searched for published studies in all languages. Inclusion and exclusion criteria were defined a priori. Eighteen probable risk factors were evaluated, and outcomes were expressed in the case of dichotomous variables, as an odds ratio (OR) (with a 95% confidence interval, (CI)). RESULTS When patient-related risk factors were analyzed, the ORs for female gender was 1.46 (95%CI: 1.30-1.64); for previous pancreatitis 2.03 (95%CI: 1.31-3.14); for previous PEP was 2.90 (95%CI: 1.87-4.48); for Sphincter of Oddi dysfunction (SOD) was 2.04 (95%CI: 1.73-2.33) and for Intraductal papillary mucinous neoplasm (IPMN) was 3.01 (95%CI: 1.34-6.77). Four endoscopy-related factors were confirmed: the OR for difficult cannulation was 3.49 (95%CI: 1.364-8.925); for endoscopic sphincterotomy (EST) it was 1.39 (95%CI: 1.09-1.79); for precut sphincterotomy it was 2.25 (95%CI: 1.70_2.96); and for main pancreatic duct injection it was 1.58 (95%CI: 1.21-2.08). CONCLUSIONS Female gender, previous pancreatitis, previous PEP, SOD, IPMN, difficult cannulation, EST, precut sphincterotomy and main pancreatic duct injection are risk factors for post-ERCP pancreatitis.

Abstract
OBJECTIVE The aim of this study was to assess the clinical effect of diclofenac administered as a single dose for the prevention of postprocedure pancreatitis in a consecutive series of patients who had undergone endoscopic retrograde cholangiopancreatography (ERCP). METHODS Patients with a native papilla Vateri subjected to ERCP during 2010 (control group, n = 218) and 2012 (diclofenac group, n = 182) were included. Patients with a history of chronic pancreatitis or recent acute pancreatitis were excluded. From January 2012, a rectal suppository containing 100 mg of diclofenac was administered immediately after endoscopy in all patients. The primary outcome of post-ERCP pancreatitis was assessed retrospectively by reviewing the patients' charts. RESULTS The overall incidence of post-ERCP pancreatitis was 32 (14.7%) of the 218 patients in the control group and 9 (4.9%) of the 182 patients in the diclofenac group (P = 0.002). Moderate to severe pancreatitis occurred in 22 (10.1%) of the 218 patients in the control group versus 8 (4.4%) of the 182 patients in the diclofenac group (P = 0.036). CONCLUSIONS This controlled cohort study suggests that the implementation of a single dose of 100 mg of diclofenac rectally administered significantly reduces the incidence of post-ERCP pancreatitis in an unselected material of patients with native papilla.

Abstract
Background A preliminary study has shown increased pancreatic fat in patients with idiopathic pancreatitis and sphincter of Oddi dysfunction. In this study, we aimed to determine if an increased quantity of pancreatic fat is an independent risk factor for pancreatitis post-endoscopic retrograde cholangiopancreatography (ERCP). Methods In this case control study, we retrospectively reviewed a local radiological and ERCP database to identify patients who had had abdominal magnetic resonance imaging (MRI) followed by ERCP no more than 60 days later between September 2003 and January 2011. Percentage of fat was determined by recording signal intensity in the in-phase (Sin) and out-of-phase (Sout) T1-weighted gradient sequences, and calculation of the fat fraction as (Sin − Sout)/(Sin) × 2 by an abdominal radiologist blinded to clinical history. Controls matched for age, gender, and other pancreatobiliary disease were selected from a group with no post-ERCP pancreatitis (before fat content of the pancreas was analyzed). Results Forty-seven patients were enrolled. Compared with controls, subjects with post-ERCP pancreatitis were similar in terms of age (41.4 years versus 41.1 years), gender (21.2% versus 20.2% males), pancreatobiliary disease characteristics, and most ERCP techniques. Measurements of pancreatic head, body, and tail fat and body mass index were similar in patients and controls. Conclusion Increased pancreatic fat on MRI criteria is not an independent predictor of post-ERCP pancreatitis.

Abstract
BACKGROUND Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Several clinical trials used glyceryl trinitrate (GTN) to prevent the incidence of post-ERCP pancreatitis (PEP). However, the results were still controversial. OBJECTIVE To conduct a meta-analysis of published, full-length, randomized controlled trials evaluating the effect of prophylactic GTN on the prevention of PEP, improve the rate of cannulation and the prevention of hyperamylasemia. METHODS Literature searches were conducted using PubMed, EMBASE, The Cochrane Library and Web of Knowledge databases, using keywords "post-ERCP" and "pancreatitis" and limited in randomized controlled trials. RESULTS Twelve RCTs involving 2649 patients were included. Eleven RCTs compared GTN with placebo for PEP prevention. Meta-analysis showed the overall incidence of PEP was significantly reduced by GTN treatment (RR 0.67; 95% CI, 0.52-0.87). Nevertheless, GTN administration did not decrease the incidence of moderate to severe PEP (RR 0.70; 95% CI, 0.42-1.15). Subgroup analyses revealed that GTN administered by sublingual was more effective than transdermal and topical in reducing the incidence of PEP. Besides, the prophylactic effect of GTN was far more obvious in the group of high PEP incidence than in the group of low PEP incidence. Additionally, the incidence of hyperamylasemia was significantly reduced by GTN treatment (RR 0.69; 95% CI, 0.54-0.90). No differences of the successful cannulation rate of bile ducts (RR 1.03; 95% CI, 0.99-1.06) attributable to GTN were observed. CONCLUSION Prophylactic use of GTN reduced the overall incidence of PEP and hyperamylasemia. However, GTN was not helpful for the severity of PEP and the rate of cannulation.

Abstract
Acute pancreatitis remains the most frequent complication of endoscopic retrograde cholangiopancreatography (ERCP), with reported incidence rates that have changed little over several decades. Patient- and procedure-related risk factors for post-ERCP pancreatitis (PEP) are well-defined. Effective measures to prevent PEP have been identified, including improvements in cannulation techniques and pancreatic stenting, as well as pharmacological intervention. Pharmacotherapy has been widely studied in the prevention of PEP, but the effect in averting PEP has been inconclusive. Although pharmacological prophylaxis is appealing, attempts to find an ideal drug are incomplete. Most available data on the efficacy of pharmacological agents for PEP prophylaxis have been obtained from patients at average risk for PEP. However, recently, a randomized prospective controlled trial of rectal nonsteroidal anti-inflammatory drugs (NSAIDs) to prevent PEP in high-risk patients was published. The results revealed that rectal indomethacin reduced the incidence of PEP significantly. Thus, rectal administration of diclofenac or indomethacin immediately before or after ERCP is used routinely to prevent PEP. However, additional studies with NSAIDs using large numbers of subjects are necessary to confirm the prophylactic effect of these drugs and to establish whether they act synergistically with other prophylactic interventions, including pancreatic stenting.

Does leaving a main pancreatic duct stent in place reduce the incidence of precut biliary sphincterotomy-associated pancreatitis? A randomized, prospective study. Gastrointest Endosc 2013; 77:209-16. [PMID: 23084272 DOI: 10.1016/j.gie.2012.08.022] [Citation(s) in RCA: 67] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2012] [Accepted: 08/21/2012] [Indexed: 12/17/2022]
Abstract
BACKGROUND Pancreatitis is the most common major complication of ERCP and precut endoscopic sphincterotomy (ES). Prophylactic pancreatic duct (PD) stent placement has been shown to reduce the incidence and severity of post-ERCP pancreatitis (PEP) in high-risk settings. OBJECTIVE To determine whether leaving a main PD stent in place after precut ES would reduce the incidence and severity of PEP. DESIGN Single-center, randomized, prospective study. SETTING Tertiary care ERCP referral center. PATIENTS Consecutive patients who underwent ERCP with a clear indication for biliary access and standard biliary ES whereby free cannulation of the bile duct was not possible and precut ES was undertaken. INTERVENTIONS When free bile duct cannulation for ES was not possible and selective PD cannulation was achieved, a PD stent was placed. Using the PD stent as a guide, we used a needle-knife sphincterotome to perform precut ES. The patients were then randomized to either leaving the PD stent in place for 7 to 10 days (stent group) or immediate removal after the procedure (stent removed group). The remaining patients who did not undergo selective PD cannulation and stent placement were not randomized (no stent group) and had a free-hand needle-knife ES performed. MAIN OUTCOME MEASUREMENTS Patients were prospectively followed for the development of complications. Standardized criteria were used to diagnose and grade the severity of PEP. RESULTS A total of 151 patients were enrolled. The groups were similar with regard to patient demographics and patient and procedure risk factors for PEP. The overall incidence of PEP was 13.2% (20/151). It occurred in 4.3% (2/46), 21.3% (10/47), and 13.8% (8/58) of patients in the stent, stent removed, and no stent groups, respectively. The stent group had a significantly lower frequency and severity of PEP compared with the stent removed group (4.3% vs 21.3%; P = .027 for frequency and 0% vs 12.8%; P = .026 for moderate and severe pancreatitis). LIMITATIONS Single center. Randomization scheme not optimal. CONCLUSIONS These data suggest that placing and maintaining a PD stent for needle-knife precut ES reduces the frequency and severity of postprocedure pancreatitis.

Abstract
BACKGROUND A fatty meal before ERCP relaxes the sphincter of Oddi and may facilitate biliary cannulation. OBJECTIVE To assess the effect of an oral fatty meal before ERCP on time to and success rate of biliary cannulation. DESIGN Human clinical study. SETTING Tertiary ERCP center. PATIENTS Adult patients with intact papilla undergoing ERCP for presumed biliary pathology. INTERVENTIONS Patients arriving more than 1 hour before the procedure were given oil by mouth. Patients not receiving oil served as controls. The need for a precut sphincterotomy was considered a failure of initial cannulation. MAIN OUTCOME MEASUREMENTS Appearance of the papillary orifice, bile flow, cannulation success rate, cannulation and fluoroscopy times. RESULTS A total of 86 patients received oil (mean age 52.8 years; 40% male), and 103 patients served as controls (mean age 53.3 years; 49% male). The papillary orifice was open in 52 of 86 (61%) and 38 of 103 (37%) patients in the oil and control groups, respectively (P = .002). Bile flow was seen in 59 of 86 (68%) and 50 of 103 (49%) patients, respectively (P = .009). The overall initial biliary cannulation success rate was 80 of 86 (93%) and 97 of 103 (94%), respectively (P = .77). There was no difference in cannulation success rates, cannulation, and fluoroscopy times for fellows or faculty endoscopists in each group. No pulmonary aspiration was seen in either group. LIMITATIONS Unblinded study. CONCLUSIONS The biliary orifice appeared more open and bile flow was seen in more patients receiving oil, but there was no difference in successful biliary cannulation rates and cannulation and fluoroscopy times in the 2 groups.

Abstract
Purpose Direct visualization of pancreatic ductal tissue is critical for early diagnosis of pancreatic diseases and for guiding therapeutic interventions. A novel, ultrathin (5 Fr) scanning fiber endoscope (SFE) with tip-bending capability has been developed specifically to achieve high resolution imaging as a pancreatoscope during endoscopic retrograde cholangiopancreatography (ERCP). This device has potential to dramatically improve both diagnostic and therapeutic capabilities during ERCP by providing direct video feedback and tool guidance to clinicians. Methods Invasiveness of the new tip-bending SFE was evaluated by a performance comparison to ERCP guide wires, which are routinely inserted into the pancreatic duct during ERCP. An in vitro test model with four force sensors embedded in a synthetic pancreas was designed to detect and compare the insertion forces for 0.89 mm and 0.53 mm diameter guide wires as well as the 1.7 mm diameter SFE. Insertions were performed through the working channel of a therapeutic duodenoscope for the two types of guide wires and using a statistically similar direct insertion method for comparison to the SFE. Results Analysis of the forces detected by the sensors showed the smaller diameter 0.53 mm wire produced significantly less average and maximum forces during insertion than the larger diameter 0.89 mm wire. With the use of tip-bending and optical visualization, the 1.7 mm diameter SFE produced significantly less average force during insertion than the 0.89 mm wire at every sensor, despite its larger size. It was further shown that the use of tip-bending with the SFE significantly reduced the forces at all sensors, compared to insertions when tip-bending was not used. Conclusion Combining high quality video imaging with two-axis tip-bending allows a larger diameter guide wire-style device to be inserted into the pancreatic duct during ERCP with improved capacity to perform diagnostics and therapy.

Abstract
Background. The present study sought and compared the utility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in the elderly and younger people in a great sample of Iranian population. Methods. Our study involved 780 patients undergoing diagnostic and therapeutic ERCP at the Taleghani hospital in Tehran between 2010 and 2011; among them, 558 patients were less than 70 years old and others were 70 years old or older. The patients were prospectively identified and data including clinical and biochemical features, ERCP procedures, ERCP diagnosis, and ERCP complications were gathered on them prospectively. Results. Clinical manifestations were comparable in young and older groups except for hepatosplenomegaly and constipation that were more prevalent in the elderly. Laboratory findings were similar in both groups other than mean levels of alkaline phosphatase, hemoglobin and albumin levels, which were higher in the elderly group. Selective biliary cannulation was technically more successful in the younger than in others (89.0% versus 81.8%). Common bile duct stone was the most frequent diagnosis in both young and older groups (36.6% and 45.9%, resp.), whereas ERCP was reported to be normal in 13.4% of the younger and 5.0% of the elderly patients. Post-ERCP complications were observed in 4.8% of patients aged less than 70 years in comparison with 2.3% of patients aged over 70 years. The most frequent complication was pancreatitis that was significantly more developed in young than older patients (3.6% versus 1.5%; OR: 8.216, P = 0.015). Conclusion. Diagnostic ERCP is safe and well tolerated in the elderly and even associated with significantly less risk than the younger.

Abstract
Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is one of the most common and serious complications of ERCP, which has become a major concern for digestive endoscopists. In the present study, we examine whether pancreatic duct stenting can reduce the incidence of PEP. Forty patients who underwent an ERCP in our hospital were selected according to their risk factors for PEP. They were randomly divided into two groups: (1) 20 subjects received a pancreatic duct stenting after ERCP to prevent pancreatitis (stent group, S); and (2) the other 20 subjects did not receive pancreatic duct stenting after ERCP (non-stent group, NS). Urine and serum amylase, and serum lipase were determined after the operation; symptoms of abdominal pain were monitored; cost of hospitalization was evaluated for the comparison. The results show that (1) 18 cases developed PEP, and they were significantly less in S group than in NS group (4 vs. 14 cases; P < 0.01); (2) Serum amylase was significantly lower in S group than in NS group (197.8 ± 339.7 vs. 825.4 ± 1253.4 U/l, respectively; P < 0.05); (3) The intensity of abdominal pain was 3.4 ± 0.8 in S group, compared to 4.1 ± 1.2 in NS group; (4) Duration of pharmaceutical treatment was not significantly different between the two groups (4.2 ± 1.4 vs. 6.1 ± 2.3 days, in S and NS group, respectively); and (5) The total hospitalization cost was significantly less in S group (8928 ± 2635 RMB) than in NS group (11288 ± 4325 RMB; P < 0.05). It is concluded that pancreatic duct stenting can reduce the incidence of PEP, shorten the duration of hospitalization, and therefore, lessen patients' financial burden. It is shown to be an effective way to prevent PEP.

Abstract
BACKGROUND AND AIMS Postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) is one of the most common and serious complications after endoscopic retrograde cholangiopancreatography (ERCP). This study aims to test the hypothesis that the incidence of PEP declined over time due to improved patient selection and/or endoscopic equipment and endoscopic techniques. Therefore, we compared the incidence and risk factors of PEP between four arbitrary chronologically stratified groups. METHODS A total of 7,168 cases of ERCP procedures were retrospectively analyzed. According to the different developmental stages of ERCP equipment and techniques, cases were divided into four groups. The incidence rates and major risk factors for acute PEP were compared between groups. RESULTS Among the 7,168 cases, the overall incidence of PEP was 3.70% (265/7,168). When analyzed against each stage of ERCP development, the incidence of PEP was 4.09% (77/1,884) in stage I, 5.79% (86/1,489) in stage II, 3.95% (62/1,568) in stage III and 1.80% (40/2,227) in stage IV. By univariate analysis, pancreatic stent placement (OR: 0.300) and use of propofol-balanced anesthesia (OR: 0.632) seem to be protective factors for acute PEP. By multivariate analysis, the following risk factors for PEP could be identified: repeated cannulation (OR: 3.462), pancreatic duct injection (OR: 3.218), balloon dilation of biliary sphincter (OR: 2.847), papillae precut (OR: 2.493), nonselective high-pressure injection (OR: 1.428), excessive electrocoagulation incision (OR: 1.263), history of pancreatitis (OR: 3.843) and suspected sphincter of Oddi dysfunction (OR: 1.782). CONCLUSIONS Improved technical procedures were associated with a significant reduction in the incidence of PEP. Risks for developing PEP may be minimized by constant improvement in ERCP techniques, such as routine use of a guidewire, highly selective cannulation, pancreatic stent placement and cautious incision.

Abstract
BACKGROUND Several studies have evaluated predictors for complications of endoscopic retrograde cholangiopancreatography (ERCP), but their relative importance is unknown. In addition, currently used blood tests to detect post-ERCP pancreatitis are inconsistent. The aim of this study was to determine predictors of post-ERCP complications that could discriminate between patients at highest and lowest risk of post-ERCP complications and to develop a model that is able to identify patients that can safely be discharged shortly after ERCP. METHODS In a single-center, retrospective analysis over the period 2002-2007, predictors of post-ERCP complications were evaluated in a multivariable analysis and compared with those identified from a literature review. A prognostic model was developed based on these risk factors, which was further evaluated in a prospective patient population. RESULTS From our retrospective analysis and literature review, we selected the eight most important risk factors for post-ERCP pancreatitis and cholangitis. In the prognostic model, the risk factors (precut) sphincterotomy, sphincter of Oddi dysfunction, younger age, female gender, history of pancreatitis, pancreas divisum, and difficult cannulation accounted for a score of 1 each, whereas primary sclerosing cholangitis (PSC) accounted for a score of 2. A sum score of 4 or more in the prognostic model was associated with a high risk of developing pancreatitis and cholangitis (27%; 6/22) in the prospective patient population, whereas a sum score of 3 or less was associated with a low to intermediate risk (8%; 20/252). CONCLUSIONS We identified specific patient- and procedure-related factors that are associated with post-ERCP complications. The prognostic model based on these factors is able to identify patients who can be safely discharged the same day after ERCP.

Abstract
The strength of functional imaging lies in its ability to detect malignant disease irrespective of lesion morphology. In this setting, 18FDG-PET can complement management by providing a more accurate diagnosis. When combined as an adjunct to CT, 18FDG-PET can increase the sensitivity, specificity, and accuracy for detecting a pancreatic malignancy, especially in patients in whom CT alone fails to identify a discrete mass or in whom biopsy results are indeterminate. This capability is accentuated with small lesions of the pancreas. 18FDG-PET is significantly more sensitive in detecting metastatic disease than conventional CT imaging. Moreover, 18FDG-PET is able to differentiate tumor response to therapy in the postoperative setting, and could potentially serve to monitor recurrence patterns in the setting of neoadjuvant or adjuvant chemoradiotherapy. Finally, as 18FDG-PET/CT fusion modalities become more widespread and technical advances in image acquisition progress, 18FDG-PET will continue to have an increasing role in the diagnosis, staging, and surveillance of pancreatic cancer, integrating anatomic information with functional imaging.

Abstract
BACKGROUND AND AIM The occurrence of peri-procedural myocardial ischemia with endoscopic retrograde cholangiopancreatography (ERCP) has been documented, but its significance remains controversial. This study aimed to investigate the incidence and risk factors of myocardial ischemia during ERCP procedures and to analyze the potential association between myocardial ischemia and post-ERCP complications. METHODS Ambulatory 24-h ST-segment monitoring from 30 min prior to 24 h after ERCP was obtained on 71 patients from September 2006 to August 2007. Changes in vital signs during ERCP, post-ERCP complications, and their outcomes were recorded and analyzed. RESULTS Cardiac ischemia occurred in 13 patients (18.3%) during ERCP and one patient developed myocardial infarction. More patients in the ischemic group (38.5%) than in the non-ischemic group (5.2%) had ST-T changes in pre-ERCP resting electrocardiography (P < 0.01). Hypotension during ERCP was found only in the ischemic group (15.4% vs 0%; P = 0.03). Patients with cardiac ischemia during ERCP had a significantly higher rate of elevated serum amylase and lipase levels (53.8% vs 15.5%; P < 0.01) and post-ERCP pancreatitis (30.8% vs 6.9%; P = 0.03). Multivariable logistic regression analysis revealed that cardiac ischemia during ERCP (OR: 5.21, P = 0.050) and pancreatic duct cannulation (OR: 5.7, P = 0.036) were independent predictors for post-ERCP pancreatitis. CONCLUSIONS ST-T changes on resting electrocardiography and intra-procedural hypotension are risk factors of myocardial ischemia during ERCP. Post-ERCP hyperamylasemia, hyperlipasemia, and pancreatitis were associated with myocardial ischemia during ERCP.

Dig Liver Dis 2010; 42:567-70. [PMID: 20018574 DOI: 10.1016/j.dld.2009.10.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2009] [Revised: 10/19/2009] [Accepted: 10/28/2009] [Indexed: 12/11/2022]
Abstract
BACKGROUND Acute pancreatitis is a complication of endoscopic retrograde cholangio-pancreatography. Aim of the study was to compare endoscopic retrograde cholangio-pancreatography-related acute pancreatitis with attacks caused by other factors. METHODS A series of consecutive patients with non-endoscopic retrograde cholangio-pancreatography-related acute pancreatitis referred to our hospital in 2007-2008 were examined retrospectively, and compared with the same number of patients with post-endoscopic retrograde cholangio-pancreatography acute pancreatitis done in the same institution. Both groups comprised 116 patients and were comparable for mean age, sex, and body mass index. Duration of abdominal pain, pancreatic enzyme elevation, hospital stay, and type of analgesia administered were retrieved. RESULTS There were no differences between the groups as regards the severity of pancreatitis, mortality rate and hospitalisation, although mortality was double in severe post-endoscopic retrograde cholangio-pancreatography acute pancreatitis. In the mild acute pancreatitis cases, serum amylase fell 50% from the peak in a mean of 46.4h (range 24-72) in group 1 and 38.9h (range 24-72) in group 2 (p<0.001). The peak amylase serum level halved within 48h in 73.6% of cases with non-endoscopic retrograde cholangio-pancreatography-related acute pancreatitis, and in 92% of patients with endoscopic retrograde cholangio-pancreatography-related acute pancreatitis (p<0.001). CONCLUSIONS Non-endoscopic retrograde cholangio-pancreatography- and endoscopic retrograde cholangio-pancreatography-induced pancreatitis did not differ as regards severity, hospital stay or mortality; in mild pancreatitis, serum amylase halved significantly sooner in post-endoscopic retrograde cholangio-pancreatography cases.

Abstract
An increase in the serum concentration of pancreatic enzymes (amylase and lipase) was reported in a proportion of imatinib-resistant and/or intolerant Philadelphia-positive chronic myeloid leukemia patients treated with nilotinib. Acute pancreatitis was very rare, and the relevance of these laboratory alterations remains unknown. We report on 8 chronic myeloid leukemia patients who developed serum lipase/amylase elevation during treatment with nilotinib. After a median follow-up of 26 months, none of these patients developed an acute pancreatitis or clinical signs of pancreatic disease. Pancreatic hyperenzymemia never led to permanent drug discontinuation and required nilotinib temporary interruption in one case only. The median cumulative duration of dose interruptions and response to treatment were comparable in patients with or without pancreatic enzyme elevation. The mechanisms of action of nilotinib on pancreatic enzymes deserves to be investigated: however, in our experience, the relevance of pancreatic hyperenzymemia was clinically very limited.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are invaluable tools in the diagnostic and therapeutic evaluation and management of a variety of pancreatobiliary disorders. Along with a significant refinement in the equipment and techniques used has come a recent trend toward aggressive therapeutic interventions. Because of the technical nature of these procedures and the characteristics of the patients, post-procedural complications may occur, ranging from minor (requiring brief hospitalization) to severe (causing permanent disability or death). This review summarizes these complications and outlines strategies to minimize them.

Abstract
Double-balloon endoscopy (DBE) was developed as a new technique for visualization of and intervention in the entire small intestine. In DBE, the intestinal walls are held apart by a balloon attached to the distal end of a soft overtube. DBE has been reported worldwide to be very useful for not only diagnosis but also endoscopic therapy. Biopsy samples of small intestinal tumors can be obtained using DBE, and the appropriate treatment can be selected before a surgical procedure. For inflammatory diseases, DBE can reveal the localization of ulcers in the lumen (on the mesenteric or antimesenteric side), which is important for differential diagnosis. Some endoscopic therapies such as hemostatic procedures, polypectomy, and dilation therapy for benign strictures can be performed in the same manner as in the large intestine. DBE may also be suitable for colonoscopy for difficult insertion cases and therapeutic procedures such as endoscopic submucosal dissection. Furthermore, a double-balloon endoscope can be selectively inserted into the afferent loop to perform endoscopic retrograde cholangiopancreatography in patients with Roux-en-Y anastomosis, allowing various kinds of endoscopic treatments for biliary diseases to be successfully performed. Endoscopic therapy in the small intestine, whose wall is very thin, should be performed with special care to avoid complications such as bleeding and perforation. In the future, improvement is expected in terms of maneuverability, therapeutic capability, and imaging technology such as the addition of a magnifying function and flexible spectral imaging color enhancement. We anticipate that DBE will contribute to the establishment of medical science of the small intestine and to research elucidating the mechanisms of small intestinal diseases.

Do the changes in the serum levels of IL-2, IL-4, TNFalpha, and IL-6 reflect the inflammatory activity in the patients with post-ERCP pancreatitis? Clin Dev Immunol 2008; 2008:481560. [PMID: 18670651 PMCID: PMC2486352 DOI: 10.1155/2008/481560] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2007] [Revised: 03/25/2008] [Accepted: 06/02/2008] [Indexed: 12/18/2022]
Abstract
BACKGROUND Acute pancreatitis is the major complication of endoscopic retrograde cholangiopancreatography (ERCP) procedure and there are some reports showing cytokine changes in ERCP-induced pancreatits. GOALS To investigate the association between early changes (within 24 hours) in the serum interleukin (IL)-2, IL-4, tumor necrosis factor (TNF)alpha, and IL-6 levels and the development of post-ERCP pancreatitis. STUDY Forty five consecutive patients who underwent therapeutic ERCP and 10 patients with acute pancreatitis without ERCP were enrolled to the study. Serum concentrations of IL-2, IL-4, TNFalpha, and IL-6 were determined immediately before, 12 hours and 24 hours after ERCP. RESULTS Seven of the 45 patients (15.5%) developed post-ERCP pancreatitis. The levels of IL-4 at 24 hours after ERCP were significantly lower in the patients with post-ERCP pancreatitis than in those without pancreatitis, while TNFalpha levels at 12 hours after ERCP were higher in the complicated group than those of the uncomplicated group. The ratios of TNFalpha/IL-4 at 12 and 24 hours after ERCP were found significantly higher in the patients with post-ERCP pancreatitis than in those without pancreatitis. IL-6 in the complicated patients was found significantly increased at 24 hours after ERCP. CONCLUSIONS The enhancement of serum TNFalpha and IL-6 levels in the patients with ERCP-induced pancreatitis reflects the inflammatory activity. Additionally, these cytokines together with IL-4 can be used in clinical laboratory monitoring of ERCP.
