Desulfovibrio fairfieldensis is a gram-negative, curved, motile, anaerobic bacillus. D. fairfieldensis has been isolated only from human specimens and is considered a normal resident of the human gastrointestinal tract. We report the second case of Desulfovibrio bacteremia associated with choledocholithiasis and review the other reported cases of D. fairfieldensis bacteremia. ...[more]

Project description:There are no clinical guidelines for the timing of cholecystectomy (CCY) after performing therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. We tried to analyze the clinical practice patterns, medical expenses, and subsequent outcomes between the early CCY, delayed CCY, and no CCY groups of patients. 1827 choledocholithiasis patients who underwent therapeutic ERCP were selected from the nationwide population databases of two million random samples. These patients were further divided into early CCY, delayed CCY, and no CCY performed. In our analysis, 1440 (78.8%) of the 1827 patients did not undergo CCY within 60 days of therapeutic ERCP, and only 239 (13.1%) patients underwent CCY during their index admission. The proportion of laparoscopic CCY increased from 37.2% to 73.6% in the delayed CCY group. There were no significant differences (p = 0.934) between recurrent biliary event (RBE) rates with or without early CCY within 60 days of ERCP. RBE event-free survival rates were significantly different in the early CCY (85.04%), delayed CCY (89.54%), and no CCY (64.45%) groups within 360 days of ERCP. The method of delayed CCY can reduce subsequent RBEs and increase the proportion of laparoscopic CCY with similar medical expenses to early CCY in Taiwan's general practice environment.

Project description:Background & aimsCholecystectomy (CCY) after an episode of choledocholithiasis requiring endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction reduces recurrent biliary events compared to expectant management. We studied practice patterns for performance of CCY after ERCP for choledocholithiasis using data from 3 large states and evaluated the effects of delaying CCY.MethodsWe conducted a retrospective cohort study using the ambulatory surgery, inpatient, and emergency department databases from the states of California (years 2009-2011), New York (2011-2013), and Florida (2012-2014). We collected data from 4516 patients hospitalized with choledocholithiasis who underwent ERCP. We compared outcomes of patients who underwent CCY at index admission (early CCY), elective CCY within 60 days of discharge (delayed CCY), or did not undergo CCY (no CCY), calculating rate of recurrent biliary events (defined as an emergency department visit or unplanned hospitalization due to symptomatic cholelithiasis, cholecystitis, choledocholithiasis, cholangitis, or biliary pancreatitis), mortality, and cost by CCY cohort. We also evaluated risk factors for not undergoing CCY. The primary outcome measure was the rate of recurrent biliary events in the 365 days after discharge from index admission.ResultsOf the patients who underwent ERCP for choledocholithiasis, 41.2% underwent early CCY, 10.9% underwent delayed CCY, and 48.0% underwent no CCY. Early CCY reduced relative risk of recurrent biliary events within 60 days by 92%, compared with delayed or no CCY (P < .001). After 60 days following discharge from index admission, patients with early CCY had an 87% lower risk of recurrent biliary events than patients with no CCY (P < .001) and patients with delayed CCY had an 88% lower risk of recurrent biliary events than patients with no CCY (P < .001). A strategy of delayed CCY performed on an outpatient basis was least costly. Performance of early CCY was inversely associated with low facility volume. Hispanic race, Asian race, Medicaid insurance, and no insurance associated inversely with performance of delayed CCY.ConclusionsIn a retrospective analysis of >4500 patients hospitalized with choledocholithiasis, we found that CCY was not performed after ERCP for almost half of the cases. Although early and delayed CCY equally reduce the risk of subsequent recurrent biliary events, patients are at 10-fold higher risk of recurrent biliary event while waiting for a delayed CCY compared with patients who underwent early CCY. Delayed CCY is a cost-effective strategy that must be balanced against the risk of loss to follow-up, particularly among patients who are ethnic minorities or have little or no health insurance.

Project description:Background and aimsNoninvasive predictors of choledocholithiasis have generally exhibited marginal performance characteristics. We aimed to identify noninvasive independent predictors of endoscopic retrograde cholangiopancreatography (ERCP)-confirmed choledocholithiasis and accordingly developed predictive machine learning models (MLMs).MethodsClinical data of consecutive patients undergoing first-ever ERCP for suspected choledocholithiasis from 2015-2019 were abstracted from a prospectively-maintained database. Multiple logistic regression was used to identify predictors of ERCP-confirmed choledocholithiasis. MLMs were then trained to predict ERCP-confirmed choledocholithiasis using pre-ERCP ultrasound (US) imaging only and separately using all available noninvasive imaging (US/CT/magnetic resonance cholangiopancreatography). The diagnostic performance of American Society for Gastrointestinal Endoscopy (ASGE) "high-likelihood" criteria was compared to MLMs.ResultsWe identified 270 patients (mean age 46 years, 62.2% female, 73.7% Hispanic/Latino, 59% with noninvasive imaging positive for choledocholithiasis) with native papilla who underwent ERCP for suspected choledocholithiasis, of whom 230 (85.2%) were found to have ERCP-confirmed choledocholithiasis. Logistic regression identified choledocholithiasis on noninvasive imaging (odds ratio (OR) = 3.045, P = 0.004) and common bile duct (CBD) diameter on noninvasive imaging (OR=1.157, P = 0.011) as predictors of ERCP-confirmed choledocholithiasis. Among the various MLMs trained, the random forest-based MLM performed best; sensitivity was 61.4% and 77.3% and specificity was 100% and 75.0%, using US-only and using all available imaging, respectively. ASGE high-likelihood criteria demonstrated sensitivity of 90.9% and specificity of 25.0%; using cut-points achieving this specificity, MLMs achieved sensitivity up to 97.7%.ConclusionsMLMs using age, sex, race, presence of diabetes, fever, body mass index (BMI), total bilirubin, maximum CBD diameter, and choledocholithiasis on pre-ERCP noninvasive imaging predict ERCP-confirmed choledocholithiasis with good sensitivity and specificity and outperform the ASGE criteria for patients with suspected choledocholithiasis.

Project description:BackgroundExclusion of the stomach after Roux-en-Y gastric bypass (RYGB) makes access to the biliary tree very challenging for the surgeon or the endoscopist. Different techniques have been described to overcome this downside, including laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (ERCP), which is an outstanding method to access the remnant stomach in order to reach the duodenal papilla. The use of this technique is associated with a high success rate.Presentation of caseHere we present the case of a 57-year-old patient with altered RYGB anatomy. The patient underwent laparoscopic cholecystectomy. Intraoperative cholangiography revealed the presence of a stone in the common bile duct. A laparoscopy-assisted transgastric ERCP was performed successfully. During the procedure, the duodenoscope was introduced through a gastrostomy, obviating the need for an intragastric trocar. The patient evolved favorably and was discharged on second postoperative day without any complications.DiscussionTransgastric laparoscopy-assisted ERCP represents an effective approach for the management of biliary complications after RYGB, even if there is a long interval between the two interventions, as occurred in the present case. Other methods described for accessing the biliary tree in patients with altered RYGB anatomy are double-balloon ERCP and endoscopic ultrasound-directed transgastric ERCP. We elected to perform the laparoscopy-assisted approach because choledocholithiasis was diagnosed transoperatively, thus, avoiding the need for secondary procedures or interventions.ConclusionTransgastric laparoscopy-assisted ERCP is a feasible procedure with low complication rates and is used in treating patients with altered RYGB anatomy who present with biliary tract disorders. The use of transgastric laparoscopy-assisted ERCP allows endoscopic treatment and cholecystectomy to be performed in a single setting.

Project description:Acute pancreatitis (AP) is common gastrointestinal disease of varied aetiology. The most common cause of AP is gallstones, followed by alcohol abuse as an independent risk factor. With the increased need for invasive techniques to treat pancreatic and bile duct pathologies such as endoscopic retrograde cholangiopancreatography (ERCP), AP has emerged as the most frequent complication. While severe AP following ERCP is rare (0.5%), if it does develop it has a greater severity index compared to non-ERCP AP. Development of a mild form of AP after ERCP is not considered a clinically relevant condition. Differences in the clinical presentation and prognosis of the mild and severe forms have been found between non-ERCP AP and post-endoscopic pancreatitis (PEP). It has been proposed that AP and PEP may also have different immunological responses to the initial injury. In this review, we summarise the literature on clinical and inflammatory processes in PEP vs non-ERCP AP.

Project description:Among physicians who perform endoscopic retrograde cholangiopancreatography (ERCP), the relationship between procedure volume and outcome is unknown.Quantify the ERCP volume-outcome relationship by measuring provider-specific failure rates, hospitalization rates, and other quality measures.Retrospective cohort.A total of 16,968 ERCPs performed by 130 physicians between 2001 and 2011, identified in the Indiana Network for Patient Care.Physicians were classified by their average annual Indiana Network for Patient Care volume and stratified into low (<25/y) and high (?25/y). Outcomes included failed procedures, defined as repeat ERCP, percutaneous transhepatic cholangiography or surgical exploration of the bile duct?7 days after the index procedure, hospitalization rates, and 30-day mortality.Among 15,514 index ERCPs, there were 1163 (7.5%) failures; the failure rate was higher among low (9.5%) compared with high volume (5.7%) providers (P<0.001). A second ERCP within 7 days (a subgroup of failure rate) occurred more frequently when the original ERCP was performed by a low-volume (4.1%) versus a high-volume physician (2.3%, P=0.013). Patients were more frequently hospitalized within 24 hours when the ERCP was performed by a low-volume (28.3%) versus high-volume physician (14.8%, P=0.002). Mortality within 30 days was similar (low=1.9%, high=1.9%). Among low-volume physicians and after adjusting, the odds of having a failed procedure decreased 3.3% (95% confidence interval, 1.6%-5.0%, P<0.001) with each additional ERCP performed per year.Lower provider volume is associated with higher failure rate for ERCP, and greater need for postprocedure hospitalization.

Project description:BACKGROUND/AIMS:Endoscopic retrograde cholangiopancreatography (ERCP) requires a unique skill set. Currently, there is no objective methodology to assess and train a professional to perform ERCP. This study aimed to develop and validate a novel ERCP simulator. METHODS:The simulator consists of papillae presenting different anatomy and positioned in varied locations. Deep cannulation of the pancreatic duct, followed by the bile duct, was performed. The time allotted was 5 minutes. The content validity indexes (CVIs) for realism, relevance, and representativeness were calculated. Correlation between ERCP experience and simulator score was determined. RESULTS:Twenty-three participants completed the simulation. The CVIs for realism were orientation of duodenoscope to papilla (1.00), angulation of papillotome to achieve cannulation (0.71), and haptic feedback during cannulation (0.80). The CVIs for relevance were use of elevator (1.00), wheels to achieve en face orientation (1.00), and papillotome for selective cannulation (1.00). Regarding CVI for representativeness, the results were as follows: basic cannulation (0.83), papilla locations (0.83), and papilla anatomies (0.80). The novice, intermediate, and experienced groups scored 6.7±8.7, 30.0±16.3, and 74.4±43.9, respectively (p<0.0001). There was a strong correlation between the ERCP experience level and the individual's simulator score (Pearson value of 0.77, R2 of 0.60). CONCLUSION:This simulator appears to be realistic, relevant, and representative of ERCP cannulation techniques. Additionally, it is effective at objectively assessing basic ERCP skills by differentiating scores based on clinical experience.

Project description:Background & aimsIt is unclear whether participation in competency-based fellowship programs for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) results in high-quality care in independent practice. We measured quality indicator (QI) adherence during the first year of independent practice among physicians who completed endoscopic training with a systematic assessment of competence.MethodsWe performed a prospective multicenter cohort study of invited participants from 62 training programs. In phase 1, 24 advanced endoscopy trainees (AETs), from 20 programs, were assessed using a validated competence assessment tool. We used a comprehensive data collection and reporting system to create learning curves using cumulative sum analysis that were shared with AETs and trainers quarterly. In phase 2, participating AETs entered data into a database pertaining to every EUS and ERCP examination during their first year of independent practice, anchored by key QIs.ResultsBy the end of training, most AETs had achieved overall technical competence (EUS 91.7%, ERCP 73.9%) and cognitive competence (EUS 91.7%, ERCP 94.1%). In phase 2 of the study, 22 AETs (91.6%) participated and completed a median of 136 EUS examinations per AET and 116 ERCP examinations per AET. Most AETs met the performance thresholds for QIs in EUS (including 94.4% diagnostic rate of adequate samples and 83.8% diagnostic yield of malignancy in pancreatic masses) and ERCP (94.9% overall cannulation rate).ConclusionsIn this prospective multicenter study, we found that although competence cannot be confirmed for all AETs at the end of training, most meet QI thresholds for EUS and ERCP at the end of their first year of independent practice. This finding affirms the effectiveness of training programs. Clinicaltrials.gov ID NCT02509416.

Project description:Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography. The incidence of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis varies substantially and is reported around 1%-10%, although there are some reports with an incidence of around 30%. Usually, PEP is a mild or moderate pancreatitis, but in some instances it can be severe and fatal. Generally, it is defined as the onset of new pancreatic-type abdominal pain severe enough to require hospital admission or prolonged hospital stay with levels of serum amylase two to three times greater than normal, occurring 24 h after ERCP. Several methods have been adopted for preventing pancreatitis, such as pharmacological or endoscopic approaches. Regarding medical prevention, only non-steroidal anti-inflammatory drugs, namely diclofenac sodium and indomethacin, are recommended, but there are some other drugs which have some potential benefits in reducing the incidence of post-ERCP pancreatitis. Endoscopic preventive measures include cannulation (wire guided) and pancreatic stenting, while the adoption of the early pre-cut technique is still arguable. This review will attempt to present and discuss different ways of preventing post-ERCP pancreatitis.

Project description:IntroductionVarious endoscopic procedures under fluoroscopic guidance are being rapidly adopted, and radiation exposure is considered to be increasing. However, there is little concern about this issue in gastroenterology practice. This study aims to evaluate the actual radiation exposure dose (RD) during endoscopic retrograde cholangiopancreatography (ERCP) and the factors affecting the RD.MethodsIn this retrospective, single-center cohort study of 1157 consecutive patients who underwent ERCP between October 2012 and February 2017, we analyzed the influences of patient characteristics, procedure time (min), total fluoroscopy time (min), type of processing engine, experience of the endoscopist, and type of disease on the total RD (mGy).ResultsThe median procedure times were 28 min for common bile duct stones (CBDS), 25 min for distal malignant biliary obstruction (MBO), and 30 min for proximal MBO. Similarly, the median fluoroscopy times were 10.3, 8.8, and 13.4 min, and the median RDs were 167, 123, and 242 mGy, respectively. Proximal MBO required significantly longer procedure time and fluoroscopy time and resulted in greater RD than distal MBO (P = 0.0006, <0.0001, <0.0001) and CBDS (P = 0.015, <0.0001, <0.0001). Multiple linear regression showed that distal MBO and a novel processing engine negatively correlate with RD (P = 0.04, <0.0001) and that proximal MBO positively correlates with RD (P = 0.0001).DiscussionProcedure time and fluoroscopy time were significantly longer for proximal MBO than for CBDS and distal MBO. The type of disease and processing engine significantly influenced the RD during ERCP.
