Abstract Purpose The aim of this study was to report the utility of chest radiography following interventional radiology-performed ultrasound-guided thoracentesis. Materials and Methods A total of 3,998 patients underwent thoracentesis between 2003 and 2018 at two institutions. A total of 3,022 (75.6%) patients were older than 18 years old, underwent interventional radiology-performed ultrasound-guided thoracentesis, and had same-day post-procedure chest radiograph evaluation. Patient age (years), laterality of thoracentesis, procedural technical success, volume of fluid removed (mL), method of post-procedure chest imaging, absence or presence of pneumothorax, pneumothorax size (mm), pneumothorax management measures, and clinical outcomes were recorded. Technical success was defined as successful aspiration of pleural fluid. Post-procedure clinical outcomes included new patient-perceived dyspnea and hypoxia (oxygen saturations < 90% on room air). Costs associated with radiographs were estimated using Medicare and Medicaid fee schedules. Results Mean age was 56.7 ± 15.5 years. Interventional radiology-performed ultrasound-guided thoracentesis was performed on the left (n = 1,531; 50.7%), right (n = 1,477; 48.9%), and bilaterally (n = 14; 0.5%) using 5-French catheters. Technical success was 100% (n = 3,022). Mean volume of 940 ± 550 mL of fluid was removed. Post-procedure imaging was performed in the form of posteroanterior (PA) (2.6%; 78/3,022), anteroposterior (AP) (17.0%; 513/3,022), PA and lateral (77.9%; 2,355/3,022), or PA, lateral, and left lateral decubitus (2.5%; 76/3,022) chest radiographs. Post-procedural pneumothorax was identified in 21 (0.69%) patients. Mean pneumothorax size, measured on chest radiograph as the longest distance from the chest wall to the lung, was 18.8 ± 10.2 mm (range: 5.0–35.0 mm). Of the 21 pneumothoraces, 7 (33.3%) were asymptomatic, resolved spontaneously, and had a mean size of 6.4 ± 2.4 mm. Fourteen pneumothoraces, of mean size 25.0 ± 5.8 mm, required management with a pleural drainage catheter (66.6%). The overall incidence of pneumothorax requiring pleural drainage catheter placement following interventional radiology-performed ultrasound-guided thoracentesis was 0.46% (14/3,022). Of the patients requiring drainage catheter placement, 12/14 (85.7%) and 13/14 (92.9%) had dyspnea and hypoxia, respectively. Potential costs to Medicare and Medicaid, for chest radiographs, in this study, were $27,547 and $10,581, respectively. Conclusion The incidence of clinically significant pneumothorax requiring catheter drainage following interventional radiology-operated ultrasound-guided thoracentesis is exceedingly low (0.46%), and routine post-procedure chest radiographs in asymptomatic patients provide little value. Reserving post-procedure chest radiographs for patients with post-procedure dyspnea or hypoxia will result in more efficient resource utilization and health care cost savings.

Abstract Background Needle-based confocal laser endomicroscopy (nCLE) enables observation of the inner wall of pancreatic cystic lesions (PCLs) during an endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). This study prospectively evaluated the diagnostic performance of nCLE for large, single, noncommunicating PCLs using surgical histopathology or EUS-FNA cytohistopathology as a reference diagnosis. Methods From April 2013 to March 2016, consecutive patients referred for EUS-FNA of indeterminate PCLs without evidence of malignancy or chronic pancreatitis were prospectively enrolled at five centers. EUS-FNA and nCLE were performed and cystic fluid was aspirated for cytohistopathological and carcinoembryonic antigen (CEA) analysis. The diagnostic performance of nCLE was assessed against the reference standard and compared with that of EUS and CEA. This study was registered on ClinicalTrials.gov (NCT01563133). Results 206 patients underwent nCLE and 78 PCLs (mean size 40 mm, range 20 – 110 mm) had reference diagnoses (53 premalignant and 25 benign PCLs). Post-procedure pancreatitis occurred in 1.3 % of the patients. nCLE was conclusive in 71 of the 78 cases (91 %). The sensitivies and specifities of nCLE for the diagnosis of serous cystadenoma, mucinous PCL, and premalignant PCL were all ≥ 0.95 (with 95 % confidence interval from 0.85 to 1.0). The AUROC was significantly larger for nCLE than for CEA or EUS. Conclusions nCLE had excellent diagnostic performance that surpassed that of CEA and EUS for the diagnosis of large, single, noncommunicating PCLs. The nCLE procedure should be considered in patients with indeterminate PCLs to ensure a more specific diagnosis.

Abstract Background Recent evidence suggests that endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is an effective and safe alternative to percutaneous drainage (PT-GBD). We conducted a systematic review and meta-analysis to compare these two procedures in high risk surgical patients with acute cholecystitis. Methods A comprehensive electronic literature search was conducted for all articles published up to October 2017 to identify comparative studies between EUS-GBD and PT-GBD. A meta-analysis was performed on outcomes including technical success, clinical success, post-procedure adverse events, length of hospital stay, unplanned hospital readmission, need for reintervention, recurrent cholecystitis, and disease- or treatment-related mortality for these two procedures. Results Five comparative studies (206 patients in the EUS-GBD group vs. 289 patients in the PT-GBD group), were included in the final analysis. There were no statistically significant differences in technical success (odds ratio [OR] 0.43, 95 % confidence interval [CI] 0.12 to 1.58; P  = 0.21; I 2 = 0 %) and clinical success (OR 1.07, 95 %CI 0.36 to 3.16; P  = 0.90; I 2 = 44 %) between the two procedures. EUS-GBD had fewer adverse events than PT-GBD (OR 0.43, 95 %CI 0.18 to 1.00; P  = 0.05; I 2 = 66 %). Moreover, patients undergoing EUS-GBD had shorter hospital stays, with pooled standard mean difference of – 2.53 (95 %CI – 4.28 to – 0.78; P = 0.005; I 2 = 98 %), and required significantly fewer reinterventions (OR 0.16, 95 %CI 0.04 to 0.042; P <  0.001; I 2 = 32 %) resulting in significantly fewer unplanned readmissions (OR 0.16, 95 %CI 0.05 to 0.53; P  = 0.003; I 2 = 79 %). Conclusions EUS-GBD was associated with lower rates of post-procedure adverse events, shorter hospital stays, and fewer reinterventions and readmissions compared with PT-GBD in patients with acute cholecystitis who were unfit for surgery.

BACKGROUND Endoscopic ultrasound (EUS)-guided biliary drainage is becoming an option for palliation of malignant biliary obstruction. Lumen apposing metal stents (LAMS) are replacing self-expandable metal stents (SEMS). Aim of this meta-analysis was to evaluate the efficacy and safety of LAMS or SEMS for EUS-guided choledocho-duodenostomy. METHODS A meta-analysis was performed using PRISMA protocols. Electronic databases were searched for studies on EUS-guided choledocho-duodenostomy. The primary outcome was the clinical success. Technical success, re-intervention and adverse events were secondary outcomes. We used the random effects model with the DerSimonian-Laird estimation and the results were depicted using the forest plots. Furthermore, we performed analysis of the outcomes with the data stratified by selected variables. RESULTS Overall, 31 studies (820 patients) were included. The pooled rates of clinical and technical success were 93.6% (95% CI [95%CI] 88.6-96.5%) and 94.8% (95%CI 90.2-97.3%), for LAMS , and 91.7% (95%CI 88.1-94.2) and 92.7 % (95%CI 89.9-94.9%) for SEMS, respectively. The pooled rates of adverse events were 17.1% (95%CI 12.5-22.8%) for LAMS compared to 18.3% (95% CI 14.3-23.0%) for SEMS. The pooled rates of re-intervention were 10.9% (95% CI 7.7-15.3%) for LAMS compared to 13.9% (95% CI 9.6-19.7%) for SEMS. Subgroup analyses confirmed these results. CONCLUSIONS This meta-analysis shows that LAMS and SEMS are comparable in terms of efficacy for EUS-guided choledocho-duodenostomy. The use of LAMS was associated with similar clinical and technical success, post-procedure adverse events and re-intervention rate when compared with SEMS placement. These last two points require further investigation.

Abstract Background and study aims Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) is an alternative to percutaneous transhepatic biliary drainage (PTBD) for patients with malignant distal biliary obstruction in whom ERCP has failed. We studied technical success, clinical success, stent patency rate and occurrence of adverse events in patients undergoing EUS-CDS with partially-covered self-expanding metal stent (PCSEMS). Patients and methods Medical records of consecutive patients with unresectable malignant distal biliary obstruction requiring biliary drainage who underwent EUS-CDS because of failure of attempt at ERCP were reviewed. EUS-CDS was done using 6-cm, PCSEMS (Wallflex, Boston Scientific). Technical success, clinical success (more than 50 % reduction in total bilirubin at 2 weeks post-procedure), stent patency rate and adverse events (AEs) were assessed. Patients were followed up for 3 months post-procedure. Results Between January 2015 and December 2016, 30 patients underwent EUS-CDS, including 20 (67 %) with failed biliary cannulation and 10 (33 %) with duodenal stenosis. Technical success was achieved in 28 patients, all of whom also had clinical success. Median total serum bilirubin decreased from 20 mg/dL to 5 mg/dL at 2 weeks post-procedure. Three patients (10 %) had adverse events (bile leak, hemobilia, stent block in one patient each; no stent migration); none of these adverse events was major and all were managed successfully. There were no procedure-related deaths. Five patients died of disease progression in the 3-month period post-procedure, and the 3-month dysfunction-free stent patency rate was 83 %. Conclusion EUS-CDS with a PCSEMS has a high technical and clinical success. Adverse events were infrequent, minor and could be managed easily.

Abstract Introduction Conventional n-butyl-cyanoacrylate (CYA) recommended for secondary prophylaxis of gastric varices (GV) is associated with significant rebleeding and glue embolism. Limited data are available on more successful and less risky endoscopic ultrasound-guided coils and CYA (EUS-Coils-CYA) injection in GV. Methods We present a retrospective case series of 12 patients with GV bleeding managed successfully with EUS-Coils-CYA injection leading to variceal eradication in 11 patients. Results From January 2018 to June 2019, 12 cases of GV, which were either bleeding or bled recently, were included. Complete obliteration was achieved in 91.6% of patients with 100% technical success. Mean number of deployed coils and volume of injected CYA glue were 1.16 and 1.58 mL, respectively. Conclusions EUS-guided angiotherapy is an effective and safe intervention for managing GV bleeding with high technical success rate.

Abstract Background Chest radiography is the standard for diagnosing pediatric lower respiratory infections in low-income and middle-income countries. A method for interpreting pediatric chest radiographs for research endpoints was recently updated by the World Health Organization (WHO) Chest Radiography in Epidemiological Studies project. Research in India required training local physicians to interpret chest radiographs following the WHO method. Objective To describe the methodology for training Indian physicians and evaluate the training’s effectiveness. Materials and methods Twenty-nine physicians (15 radiologists and 14 pediatricians) from India were trained by two WHO Chest Radiography in Epidemiological Studies members over 3 days in May 2019. Training materials were adapted from WHO Chest Radiography in Epidemiological Studies resources. Participants followed WHO methodology to interpret 60 unique chest radiographs before and after the training. Participants needed to correctly classify ≥80% of radiographs for primary endpoint pneumonia on the post-training test to be certified to interpret research images. We analyzed participant performance on both examinations. Results Twenty-six of 29 participants (89.7%) completed both examinations. The average score increased by 9.6% (95% confidence interval [CI] 5.0–14.1%) between examinations (P<0.001). Participants correctly classifying ≥80% of images for primary endpoint pneumonia increased from 69.2% (18/26) on the pretraining to 92.3% (24/26) on the post-training examination (P=0.003). The mean scores of radiologists and pediatricians on the post-training examination were not statistically different (P=0.43). Conclusion Our results demonstrate this training approach using revised WHO definitions and tools was successful, and that non-radiologists can learn to apply these methods as effectively as radiologists. Such capacity strengthening is important for enabling research to support national policy decision-making in these settings. We recommend future research incorporating WHO chest radiograph methodology to consider modelling trainings after this approach.

ABSTRACTObjective:We derived a clinical decision rule to determine which emergency department (ED) patients with chest pain and possible acute coronary syndrome (ACS) require chest radiography.Methods:We prospectively enrolled patients over 24 years of age with a primary complaint of chest pain and possible ACS over a 6-month period. Emergency physicians completed standardized clinical assessments and ordered chest radiographs as appropriate. Two blinded investigators independently classified chest radiographs as “normal,” “abnormal not requiring intervention” and “abnormal requiring intervention,” based on review of the radiology report and the medical record. The primary outcome was abnormality of chest radiographs requiring acute intervention. Analyses included interrater reliability assessment (with κ statistics), univariate analyses and recursive partitioning.Results:We enrolled 529 patients during the study period between Jul. 1, 2007, and Dec. 31, 2007. Patients had a mean age of 59.9 years, 60.3% were male, 4.0% had a history of congestive heart failure and 21.9% had a history of acute myocardial infarction. Only 2.1% (95% confidence interval [CI] 1.1%–3.8%) of patients had radiographic abnormality of the chest requiring acute intervention. The κ statistic for chest radiograph classification was 0.81 (95% CI 0.66–0.95). We derived the following rule: patients can forgo chest radiography if they have no history of congestive heart failure, no history of smoking and no abnormalities on lung auscultation. The rule was 100% sensitive (95% CI 32.0%–10.4%) and 36.1% specific (95% CI 32.0%–40.4%).Conclusion:This rule has potential to reduce health care costs and enhance ED patient flow. It requires validation in an independent patient population before introduction into clinical practice.
