Although prior versions have been limited by computed tomography (CT) to body divergence (CTBD), the advent of digital fluoroscopic tomosynthesis with continuous real-time guidance with the Illumisite system may help to overcome CTBD. This enhanced visualization, however, will require additional radiation exposure to perform the 50-degree fluoroscopic sweep around the PPL, but data are lacking on the additional amount. The primary objective of our study is to evaluate the effective dose patients are exposed to during biopsy with this system.Methods: Single center retrospective analysis evaluating demographic data, nodule size, nodule location, diagnostic yield, incidence of complications, and radiation exposure.Results: Eighty-two patients underwent PPL biopsy from March 2021 to March 2023. The mean PPL size was 2.3±0.9 cm (0.9 to 4.9 cm) and 84% (n=69) were solid. The majority were in the peripheral lung third (53, 64.6%) and 71% (n=58) had an air bronchogram on CT chest. The mean fluoroscopy time was 5 minutes 10 seconds (± 3 min 39 s). The mean fluoroscopy cumulative air kerma (CAK) was 0.071 Gy (± 0.045 Gy) with a calculated mean effective dose of 0.997 mSv (± 0.63 mSv). The diagnostic yield was 73% (60/82). Pneumothorax occurred in 4 (5%) patients, all of which required chest tube drainage.Conclusion: Radiation exposure with the Illumisite system was less than historical reports for CT-guided biopsy or cone beam CT-guided bronchoscopic biopsies. Diagnostic yield and incidence of complications were comparable to prior reports.","PeriodicalId":15268,"journal":{"name":"Journal of Bronchology & Interventional Pulmonology","volume":"32 2","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143709681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emerging evidence suggests that respiratory physicians experienced in thoracic ultrasound may achieve comparable diagnostic yield and safety outcomes to interventional radiologists. This study aimed to determine the diagnostic yield and safety of US-PNB of accessible thoracic lesions as performed by respiratory physicians, in an Australasian context.Methods: Demographic, clinical, and procedural information was prospectively collected at a single Australian tertiary centre for patients undergoing US-PNB of peripheral lung and pleural lesions, lymph nodes, and other accessible thoracic lesions in an outpatient setting between October 3, 2016 and December 20, 2019. The final diagnosis was determined following a discussion in a lung oncology multidisciplinary meeting. Twelve-month follow-up data was reviewed.Results: One hundred and fifty-one patients underwent 162 US-PNB procedures. This included 3 patients who underwent US-PNB of separate sites, and 8 patients who underwent repeat US-PNB procedures of the same site. Overall, the diagnostic yield of US-PNB was 83% (95% CI: 76-88). Diagnostic yield varied by procedural site, with yields highest in lymph node biopsy (91%, 95% CI: 79-97) and lowest in pleural biopsy (66%, 95% CI: 50-79).

MT is usually accomplished with the use of monitored anesthesia care (MAC) and local anesthetic (LA) infiltration. There is little data regarding the analgesic benefits and use of peripheral nerve blocks (PNB) for MT.Methods: A retrospective review was done looking at patients who underwent MT at a single center in New York City from January 2021 to September 2023, comparing the procedural times, intraoperative opioid consumption, and postoperative opioid consumption in the post-anesthesia care unit (PACU) of patients who received a PNB with MAC versus MAC alone.Results: Ninety records were queried, 23 (25.6%) had a PNB, of which 14 (60.8%) received an erector spinae plane block (ESPB) and 9 (39.1%) received a serratus anterior plane block (SAPB). 67 (74.4%) received MAC alone. When comparing those who received a PNB with MAC versus MAC alone, there was a reduction in procedure time (34 vs. 40 min, P=0.007), in-room time (53 vs. 68 min, P=<0.001), median use of intraoperative opioids (milligram morphine equivalent, 3.0 vs. 6.0, P=<0.001), and overall need for dexmedetomidine (0 vs. 20.9%, P=0.04). There was no difference in the intraoperative opioid use or postoperative opioid consumption recorded in PACU.Conclusion: The addition of a PNB, either SAPB or ESPB, to MAC for MT is safe and might reduce procedural time and overall intraoperative opioid use.

However, it is unknown whether the technique of TPC placement influences pleurodesis outcomes.Methods: This is a retrospective, single-center study of patients who underwent TPC placement from 2010 through 2018. Pleurodesis success was defined as TPC removal within 90 days of placement in the setting of no further drainage and in the absence of catheter malfunction, infection, patient's choice for another treatment modality, or other catheter-related complications. Pleurodesis failure was defined as patients who did not have TPC removal within 90 days of insertion.Results: A total of 326 patients underwent TPC insertion by thoracic surgery, interventional pulmonology, or interventional radiology. Fourteen patients were excluded due to insufficient follow-up. Of the 312 patients included in the final analysis, 32.7% achieved pleurodesis. Patients who had their TPC inserted thoracoscopically achieved higher pleurodesis success compared with a percutaneous technique (61.2% vs 24.9%, P < 0.001). Thoracoscopically placed catheters had two times greater chance of removal than those inserted percutaneously (hazard ratio: 2.04, 95% CI: 1.14-3.64, P = 0.02) after controlling for pleural biopsies and sclerosing agents used during thoracoscopy.Conclusion: Thoracoscopic TPC placements may be associated with higher pleurodesis rates compared with a percutaneous technique.

However, broader adoption requires cost analysis. We conducted a 1-year cost-minimization analysis comparing SFBs and reusable flexible bronchoscopes (RFBs) at a tertiary care university hospital.Methods: We evaluated the costs per procedure, considering capital equipment, maintenance, repair, reprocessing, and overhead costs. We also analyzed the impact of annual procedure volume on costs and performed a sensitivity analysis to assess the effect of uncertainty on costs.Results: A total of 1394 bronchoscopies were performed. RFBs were less expensive for an annual volume of >50 bronchoscopies/year, with a 22% lower cost per procedure than that for SFBs (€203 vs. €259). This cost advantage became increasingly favorable with an increasing number of procedures, reaching a plateau after exceeding 250 bronchoscopies/year. The capital equipment, the annual number of bronchoscopies, and reprocessing were the major cost drivers for RFBs. During nonworking hours, the cost per procedure of RFBs ranged from €349.45 to €392.29. Using RFBs during interventions involving a high risk of bronchoscope damage (frequency of damage >10%) would increase the cost per bronchoscopy to >€263 (exceeding the cost of SFBs).Conclusion: RFBs were 22% less expensive than SFBs for services with a moderate to high volume of bronchoscopies. However, this difference could not justify using RFBs in patients with a high cross-infection risk.

However, expert panel recommendations favor assessments based on skill and knowledge. PCCM trainees have a variable exposure to the advanced procedures in the presence of interventional pulmonary (IP) fellowships, so we surveyed the PCCM program directors (PD) across the United States to assess the procedural volume and competency of their fellows.Methods: Survey invitations were emailed between April 2022 and May 2022, and responses were collected from PCCM fellowship programs. The PD assessed the competency and volume of procedures performed by PCCM fellows at the end of training. The primary objective was to determine the effect of IP fellowship or IP faculty on fellows' procedural competency. The secondary objective was to assess the same impact on procedural volume.Results: The survey response rate was 41.9% (n=109/260) with an average of 4.23 fellows/program (95% CI: 3.9-4.6). 74.5% (73/98) programs reported having access to IP faculty, while 26.5% (26/98) had an AABIP-accredited IP fellowship.

Patient and lesion data, outcomes, and radiation indices were collected. Existing literature on 3D image guidance for bronchoscopic lung nodules was reviewed to compare reported radiation doses.Results: Combining LungVision with Cios Spin significantly reduced radiation dose in all cases compared with using Cios Spin alone: Cumulative air kerma (Ka,r) reduced from 238.7 to 119.1 mGy (P=0.03), and air kerma-area product (KAP) decreased from 28.19 to 15.09 Gy·cm2 (P=0.03). For biopsy cases, LungVision led to notable dose reductions: Ka,r of 279 to 129.1 mGy, and KAP of 30.70 to 16.27 Gy·cm2. LungVision notably reduced radiation indices in 7 paired spins, isolating the 3D imaging algorithm as the sole variable with the same Cios Spin C-arm. A literature review provides additional context on radiation for bronchoscopic biopsies.Conclusion: Following the \"as low as reasonably achievable\" (ALARA) principle minimizes ionizing radiation exposure, benefiting patients and operators.

Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.Methods: Individuals referred for suspected sarcoidosis were considered for enrollment. Bronchoscopy with both WL and NBI was conducted, followed by EBB. The main objectives were to characterize NBI abnormalities in this patient population and determine the incremental yield of NBI-directed EBB.Results: In our cohort of 100 suspected sarcoidosis patients (66% male, median age 42), 88 were diagnosed with sarcoidosis, through cytopathology (n=78) or clinical evaluation (n=10). NBI high-grade lesions were more common than WL high-grade lesions (58% vs. 27%, difference 31%, 95% CI 18.3-42.5% P<0.001). High-grade WL EBB were more likely to be positive than low-grade WL biopsies [20/31 (65%) vs. 20/91 (22%), odds ratio (OR) 6.5, 95% CI 2.7-15.6, P<0.01]). Conversely, high-grade NBI lesions were no more likely to be positive than low-grade NBI lesions [23/63 (37%) vs. 17/59, (29%), OR 1.42, 95% CI 0.66-3.0, P=0.366]. EBB positivity and false-negative EBUS-TBNA were more common in patients with Scadding stage 2 or greater, suggesting that the chest radiography stage may help select patients more likely to benefit from adjunctive EBB.Conclusion: NBI abnormalities are common in patients with sarcoidosis, but unlike WL abnormalities, do not predict the finding of granulomatous inflammation on EBB. The chest radiography stage may be useful to identify patients more likely to benefit from EBB in addition to EBUS-TBNA.","PeriodicalId":15268,"journal":{"name":"Journal of Bronchology & Interventional Pulmonology","volume":"32 2","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143006172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnostic yield of radial endobronchial ultrasound (rEBUS) guided bronchoscopic biopsies is suboptimal, despite ultrasound confirmation of navigation success. Pairing ultrathin bronchoscopy and peripheral transbronchial needle aspiration (pTBNA) may improve yield.Methods: We prospectively recruited consecutive patients undergoing Olympus MP190F ultrathin bronchoscopy with rEBUS-guided sampling of PPLs. Cases were randomized to pTBNA (Olympus Periview FLEX) either before or after the usual transbronchial forceps biopsy (TBLBx) and brush. Diagnostic yield from cytology or histopathology, clinical outcomes to a minimum 24 months follow-up and complications were recorded.Results: One hundred one sampled lesions were included (pTBNA first 61, pTBNA last 40). Overall diagnostic yield was 66.3%, with no significant difference between groups (64% vs. 70% P=0.528) or prespecified subgroups according to sampling order. Seventy lesions had an end diagnosis of malignancy, of which 50 were correctly diagnosed (71.4%). TBLBx (49/96, 49%) and pTBNA (48/101, 47.5%) had the highest individual positive yield. For 12 (11.9%) participants, pTBNA was the only positive sample. Lesions <20 mm and those with eccentric rEBUS image seemed to benefit most from this approach. Rapid on-site cytologic examination (ROSE) was associated with both positive procedural diagnosis (P=0.019) and pTBNA-positive samples (P=0.004). Pneumothorax occurred in 4% and moderate bleeding in 5%. Thirteen percent had an unplanned admission within 1 month of bronchoscopy.Conclusion: Adding pTBNA to conventional sampling through an ultrathin bronchoscope guided by rEBUS, improved diagnostic yield (11.9% additional diagnoses). The sampling sequence did not affect the yield of pTBNA.","PeriodicalId":15268,"journal":{"name":"Journal of Bronchology & Interventional Pulmonology","volume":"32 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142728914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
