Abstract
BACKGROUND Thoracoscopy is useful for diagnosing unexplained pleural effusions. A sufficient specimen volume is often difficult to obtain using forceps biopsies (FBs) but can be obtained with pleural cryobiopsies (CBs). This study aimed to assess the utility and safety of CB during thoracoscopy in the Japanese population. METHODS Patients who underwent thoracoscopic CBs at the Japanese Red Cross Medical Center between January 2017 and August 2023 were included in the study. Data were retrospectively analyzed, including clinical data, thoracoscopic findings, specimen size, diagnostic yield, and complications. The number of collected specimens and the freezing time were left to the discretion of the attending physician. RESULTS Twenty-six patients underwent thoracoscopic CB. Specimens obtained by CB were larger than those obtained by FB. Primary lung cancer was the most common cause of pleural effusion, followed by malignant pleural mesothelioma. CB contributed to the diagnosis in 24 of 26 cases (92.3%) and FB contributed to the diagnosis in 11 of 18 cases (61.1%). Severe fibrosis could be diagnosed in all 3 cases by CB, but not by FB. The common complications of CB included bleeding at the biopsy site and atelectasis, but no severe complications occurred. CONCLUSIONS The utility and safety of thoracoscopic CB for diagnosing pleural effusions in Japan were verified. The diagnostic yield, specimen size, and safety profile of CB support the diagnostic utility of this method.

Ishii S, Ishida A, Sugiura Y, Takasaki J, Izumi S, Hojo M. Examination of the utility of cryobiopsy for tuberculous pleurisy in thoracoscopy: A report of seven cases. Respir Med Case Rep 2023; 43:101840. [PMID: 37064571 PMCID: PMC10091113 DOI: 10.1016/j.rmcr.2023.101840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 02/12/2023] [Accepted: 03/17/2023] [Indexed: 04/03/2023] Open
Abstract
Thoracoscopy under local anaesthesia is effective for the diagnosis of tuberculous pleurisy (TP), mesothelioma and pleural metastases of lung cancer, etc. It has recently been reported that cryobiopsy is useful for obtaining sufficient tissue, achieving a greater depth, and avoiding crush artefact than biopsy forceps. However, the utility of the tissue obtained by cryobiopsy for culture for diagnosing TP is unknown. We compared positivity rates of tissue culture obtained by biopsy forceps and cryobiopsy in seven TP patients. The median tissue size was 2 mm by biopsy forceps and 6 mm by cryobiopsy. The pathological diagnostic rate of pleural tissue was 85.7% with biopsy forceps and 100% with cryobiopsy. However, the positivity rate of tissue culture was 57.1% with biopsy forceps and 28.5% with cryobiopsy. Since rapid freezing with a cryoprobe makes it difficult for bacteria to grow, it is possible that cryobiopsy might not be useful for obtaining a tissue culture in TP cases. However, since the sample size of this study was small, analysis of more cases is required to confirm our results.

Abstract
BACKGROUND Pleural biopsy findings offer greater diagnostic sensitivity in malignant pleural effusions compared with pleural fluid. The adequacy of pleural biopsy techniques in achieving molecular marker status has not been studied, and such information (termed "actionable" histology) is critical in providing a rational, efficient, and evidence-based approach to diagnostic investigation. RESEARCH QUESTION What is the adequacy of various pleural biopsy techniques at providing adequate molecular diagnostic information to guide treatment in malignant pleural effusions? STUDY DESIGN AND METHODS This study analyzed anonymized data on 183 patients from four sites across three countries in whom pleural biopsy results had confirmed a malignant diagnosis and molecular profiling was relevant for the diagnosed cancer type. The primary outcome measure was adequacy of pleural biopsy for achieving molecular marker status. Secondary outcomes included clinical factors predictive of achieving a molecular diagnosis. RESULTS The median age of patients was 71 years (interquartile range, 63-78 years), with 92 of 183 (50%) male. Of the 183 procedures, 105 (57%) were local anesthetic thoracoscopies (LAT), 12 (7%) were CT scan guided, and 66 (36%) were ultrasound guided. Successful molecular marker analysis was associated with mode of biopsy, with LAT having the highst yield and ultrasound-guided biopsy the lowest (LAT vs CT scan guided vs ultrasound guided: LAT yield, 95%; CT scan guided, 86%; and ultrasound guided, 77% [P = .004]). Biopsy technique and size of biopsy sample were independently associated with successful molecular marker analysis. LAT had an adjusted OR for successful diagnosis of 30.16 (95% CI, 3.15-288.56; P = .003) and biopsy sample size an OR of 1.18 (95% CI, 1.02-1.37) per millimeter increase in tissue sample size (P < .03). INTERPRETATION Although previous studies have shown comparable overall diagnostic yields, in the modern era of targeted therapies, this study found that LAT offers far superior results to image-guided techniques at achieving molecular profiling and remains the optimal diagnostic tool.

Abstract
INTRODUCTION :Cryobiopsy is a novel diagnostic technique for thoracic diseases which has been extensively investigated over the past 20 years. It was originally proposed for the diagnosis of endobronchial lesions and diffuse parenchymal lung disease due to limitations of conventional sampling techniques including small size and presence of artifacts. AREAS COVERED :We will review recent evidence related to the expanding use of cryobiopsy in thoracic diseases. To identify references, the MEDLINE database was searched from database inception until May 2022 for case series, cohort studies, randomized controlled trials, systematic reviews and meta-analyses related to cryobiopsy. EXPERT OPINION Cryobiopsy has expanding applications in the field of thoracic diseases. Evidence to support transbronchial cryobiopsy as an alternative to surgical lung biopsy is increasing and was recently endorsed as a conditional recommendation by the latest American Thoracic Society guideline update for Idiopathic Pulmonary Fibrosis. Developments in technology and technique, in particular the availability of a 1.1 mm flexible cryoprobe, have extended applications to pulmonary diseases, including diagnosis of interstitial lung diseases, peripheral pulmonary lesions, and lung transplant rejection.

Abstract
The effectiveness of thoracoscopic biopsy as a diagnostic method for pleural diseases has been reported; however, obtaining a sufficient specimen size is sometimes difficult. Therefore, an ancillary technique, the precut technique using an injection needle, was devised to address this problem. This study aimed to evaluate the effectiveness and safety of the novel precut technique in patients with undiagnosed pleural effusion. This retrospective study included 22 patients who underwent pleural biopsy using the precut technique to examine exudative pleural effusion of unknown etiology. Thoracoscopy was performed under local anesthesia. The biopsy procedure was performed as follows: a needle was inserted into the pleura around the lesion using a semiflexible thoracoscope; the needle was positioned to make an incision in the pleura while injecting 1% lidocaine with epinephrine and lifting the pleura from the fascia; 2 or 3 precut incision lines were arranged in a triangle; and the specimen was obtained from the parietal pleura using forceps or a cryoprobe. Patient data including age, number of biopsies, biopsy specimen size, pathological and final diagnosis, and postoperative complications were examined. All patients were male with an average age of 74 years. Pleural effusion was found on the right and left sides in 16 and 6 patients, respectively. The average major axis of the biopsy specimens was 18 mm (range, 10-30 mm), which was sufficient to establish a pathological diagnosis. Only 1 patient experienced minor temporal bleeding as a complication. The precut technique enabled the procurement of specimens sufficient in size for pleural biopsy.

Abstract
Background Pleural cryobiopsy is a novel technique for the diagnosis of pleural pathologies. However, the safety and feasibility of this modality compared to standard forceps for pleural biopsy has not been fully elucidated. This systematic review and meta-analysis aims to establish the efficacy and safety of cryobiopsy for evaluation of undiagnosed pleural effusion. Methods For this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, and Web of science databases up to December 16, 2021 to identify relevant articles. We included randomized controlled trials, cohort studies, retrospectives studies and case series that compared pleural cryobiopsy and forceps biopsy. A qualitative assessment was performed using the QUADAS-2 tool. Results Of the 365 articles identified by our search, 15 studies were eligible for inclusion. The specimen sizes obtained with cryobiopsy were significantly larger compared with forceps biopsy (Standard mean difference 1.16; 95 % CI: 0.51–1.82; P < 0.01). Furthermore, the cryobiopsy tissue specimens were deeper (OR 2.68; 95 % CI: 1.39–5.16; P < 0.01) and qualitatively better with less crush artifacts (OR 0.06; 95 % CI: 0.01–0.26; P < 0.01). There was no significant difference in diagnostic yield (OR 1.32; 95 % CI: 0.79–2.21; P = 0.29) and mild to moderate bleeding events (OR 1.21; 95 % CI: 0.64–2.29; P = 0.57) between pleural cryobiopsy and forceps biopsy. No publication bias was observed among these studies. Conclusions Compared to flexible forceps biopsy pleural cryobiopsy obtained larger and deeper tissue specimens with less crush artifacts but does not show superiority for diagnostic yield. Further studies are still needed to verify these findings.

Abstract
Background
Rigid thoracoscopy is the gold standard tool for diagnosing exudative pleural effusion, but sometimes it is difficult to obtain sufficient biopsies using the conventional forceps. This study evaluated the efficacy, safety, and diagnostic value of a modified technique using cryoprobe to obtain pleural biopsies during thoracoscopy.
Results
This is a single-center prospective study in patients that underwent rigid thoracoscopy using conventional rigid forceps followed by a cryoprobe at the same setting after injection of subpleural mixture of adrenaline and xylocaine. Biopsies were reviewed by an independent pathologist; any complications were recorded, and all patients were followed-up post-procedure. Twenty-four patients (12 males; mean age was 56 ± 15.1years) were included. The diagnostic yield of both rigid forceps biopsy (RFB) and cryoprobe biopsy (CPB) was 100%. CPB had more surface area than RFB with no difference regarding largest diameter (p = 0.064). RFB and CPB had similar results regarding presence of fat cells. CPB had much less crushed cells than RFB with better tissue preservation (p = 0.004). No significant complications were reported.
Conclusions
The modified cryoprobe biopsy is a highly effective and safe way for obtaining pleural biopsy besides affording good quality and size of the biopsy especially in thick firmly adherent pleura.

Abstract
BACKGROUND Dry pleural dissemination (DPD) and minimal (<10 mm thick) pleural effusion (PE) may be discovered intraoperatively as unexpected metastases. A definitive diagnostic procedure such as pleural biopsy is rarely attempted in such patients preoperatively. We retrospectively investigated the use and safety of local anesthetic thoracoscopy (LAT) as a pleural staging tool in the diagnosis of DPD and minimal PE. METHODS We reviewed 18 patients with non-small cell lung cancer (radiological DPD and minimal PE in 13 and five patients, respectively) who underwent LAT using a flex-rigid pleuroscope for pleural staging from April 2015 to September 2020. RESULTS The median age of the patients was 72 years. Nine patients (50%) were men. The dominant histological type was adenocarcinoma (n = 16). Three patients each with radiological DPD and minimal PE had visible PE on the LAT. Pleural biopsy was performed in the 16 cases in which pleural abnormalities were identified. On pleural staging, five cases were diagnosed without pleural dissemination (M0), and 13 cases were diagnosed with pleural dissemination (M1a). Only one case in which the lesion could not be identified because of pleural adhesions was false-negative. The success rates for pleural staging, sensitivity, specificity, positive predictive value, and negative predictive value were 94.4% (17/18), 92.8% (13/14), 100% (4/4), 100% (13/13), and 80.0% (4/5), respectively. There were no lung lacerations or other severe complications caused by the procedure or during blunt dissection. CONCLUSION LAT might be a useful tool for accurate pleural staging in cases with DPD and minimal PE suspected radiologically.

Abstract
OBJECTIVE Current evidence on the diagnostic yield and safety of pleural cryobiopsy (CB) is based on a series of heterogeneous studies with limited cohorts. A pooled analysis of these studies could improve the evidence and contribute to a better understanding of this new technique. METHODOLOGY We performed a systematic review and meta-analysis of published studies that included data on the yield and diagnostic safety of pleural CB compared with procedures performed using conventional flexible forceps. The heterogeneity of the analysis was evaluated by determining the I2 index, while study quality was measured with the QUADAS-2 tool. RESULTS Seven studies involving 356 patients were used for the final evaluation. In 55.6%, the etiology of the pleural effusion was malignant, 61.1% of which were lung cancer. The diagnostic yield of pleural CB was 95% (95% CI 92-97) vs. 91% (95% CI 87-94) with conventional flexible forceps (P = .019). Mild bleeding was reported in 67% of CB procedures (95% CI 62-72) compared with 85% of conventional flexible forceps procedures (95% CI 79-90) (P < .001). CB specimens were larger, and fewer artifacts were detected. A pooled analysis of the detection of molecular changes could not be performed. Heterogeneity was moderate to high, although the quality of the studies was acceptable. CONCLUSIONS Pleural CB is a safe technique with a high yield for etiological diagnosis of pleural effusion, and larger specimens with fewer artifacts are obtained. Molecular determinations should be investigated in more depth.

Abstract
Surgical intervention is occasionally required for the treatment of pleural empyema. Semirigid thoracoscopy is a safe and successful surgical approach utilized by interventional pulmonologists, conventionally utilizing flexible forceps and suction as the main tools, but they can sometimes be inefficient for more complicated cases. In debriding a case of multiloculated empyema with semirigid thoracoscopy, we report the novel use of cryotherapy in clearing adhesions from the pleural cavity. We found using the cryoprobe to be more efficient than using forceps and suggest further investigation into its use in medical thoracoscopy.

Abstract
Advanced malignancy is a prevalent cause of exudative pleural effusion. The management of malignant pleural effusion (MPE) has been the subject of several recent randomized controlled trials and excellent reviews. Less attention has been focused on another controversial and challenging aspect of MPE: establishing the diagnosis. Before selecting the optimal management strategy, the presence of an MPE must first be correctly identified with an emphasis on minimizing invasiveness and discomfort in a patient with late-stage cancer. The aim of the present review is to summarize the current knowledge about MPE diagnostics and to propose an algorithm for the diagnosis of MPE in established or suspected malignancy.

Abstract
INTRODUCTION Developing a feasible and accurate means of evaluating pleural pathology has been an ongoing effort for over 150 years. Pleural fluid cellular and biomarker analyses are simple ways of characterizing and uncovering pathologic entities of pleural disease. However, obtaining samples of pleural tissue has become increasingly important. In cases of suspected malignancy and certain infections histopathology, culture, and molecular testing are necessary to profile diseases more effectively. The pleura is sampled via several techniques including blind transthoracic biopsy, image-guided biopsy, and surgical thoracotomy. Given the heterogeneity of pleural disease, low diagnostic yields, or invasiveness no procedural gold standard has been established in pleural diagnostics. AREAS COVERED Herein, we provide a review of the literature on medical thoracoscopy (MT), its development, technical approach, indications, risks, current and future role in the evaluation of thoracic disease. Pubmed was searched for articles published on MT, awake thoracoscopy, and pleuroscopy with a focus on reviewing literature published in the past 5 years. EXPERT OPINION As the proficiency and number of interventional pulmonologists continues to grow, MT is ideally positioned to become a front-line diagnostic tool in pleural disease and play an increasingly prominent role in the treatment algorithm of various pleural pathologies.

Abstract
An 83-year-old woman presented with dyspnoea. Her chest X-ray showed a right-sided pleural effusion. Flex-rigid pleuroscopy was performed and showed a mass in the anterior portion. The mass was biopsied with conventional biopsy forceps, but the mass was solid, and sufficient tissues could not be obtained. Therefore, the mass was biopsied with a cryoprobe. The tip of the probe was attached to the mass, and it was cooled with carbon dioxide once for 5 sec and then for 7 sec in the same place. The tissue size obtained was 2 mm by conventional biopsy forceps, and 5 mm at 5 sec and 12 mm at 7 sec by cryobiopsy. Histological analysis of the conventional biopsy forceps specimen showed cancer cells in the glandular cavity, but it was not sufficient tissue for comprehensive cancer genetic panel (CGP) testing. The cryobiopsy specimens showed cancer cells and sufficient tissue for comprehensive CGP testing.

Abstract
Background Thoracoscopic pleural biopsy is an efficient procedure in patients with undiagnosed exudative pleurisy. Rigid or flexible forceps have been widely used for this procedure. Recently, the use of cryo-techniques was reported in pleural biopsy during semi-rigid thoracoscopy; however, the feasibility and safety of pleural cryobiopsy in elderly patients have not yet been fully elucidated. Case reports We describe two elderly patients who safely underwent semi-rigid thoracoscopic cryobiopsy and were diagnosed with tuberculous pleurisy. Both were >85 years of age, and chest auscultation revealed reduced breath sounds in the right lower zones. Laboratory investigations revealed an elevated level of C-reactive protein without leukocytosis in both patients. Computed tomography scan of the chest revealed right pleural effusion in both patients. Pleural fluid biochemical analysis results were indicative of an exudate. Sputum cultures demonstrated no bacterial growth and smears were negative for the presence of acid-fast bacilli. For definitive diagnosis, pleural biopsy was performed via thoracoscopic cryobiopsy. Specimens obtained from the cryoprobe demonstrated 200-300-μm caseating and non-caseating epitheloid cell granulomas with Langerhans type giant cells. Based on the above results, both patients were diagnosed with TB pleurisy. Anti-tuberculosis treatment resulted in good clinical outcome in both patients. Conclusion Cryobiopsy is easier and more efficient than biopsy with conventional forceps. Our findings in these patients suggest that semi-rigid thoracoscopic cryobiopsy might be a useful alternative diagnostic method for undiagnosed pleural effusion in elderly patients.

Abstract
A minimally invasive thoracic intervention, such as local anaesthetic thoracoscopy, can be used to collect the samples in malignant pleural lesions. But cancerous pleurisy without pleural effusion, called dry pleural dissemination, is considered difficult to perform thoracoscopy from concerns about pleural injury. We present a diagnosed case of dry pleural dissemination safely sampled using cryobiopsy using flex-rigid thoracoscope under local anaesthesia.

Abstract
BACKGROUND Pleural biopsy using either video-assisted thoracoscopic surgery or medical pleuroscopy is the current diagnostic criterion standard for pleural pathology with a high, yet imperfect, diagnostic yield. Cryobiopsy may provide greater tissue, increase depth of sampled tissue, and/or reduce crush artifact. However, its impact on diagnostic yield remains uncertain, and there are potential concerns regarding its safety too. We performed a systematic review and meta-analysis to investigate the same. METHODS We performed a systematic search of MEDLINE, Embase, and Google Scholar for studies evaluating the performance of pleural cryobiopsy, assessing the quality of each study using the Quality Assessment, Data Abstraction and Synthesis-2 tool. Using inverse variance weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed specimen characteristics and complications related to the procedure. RESULTS Seven observational studies involving 586 pleural biopsies (311 cryobiopsies and 275 flexible forceps biopsies) were evaluated. All but one study used a semi-rigid thoracoscope. Meta-analysis generated a diagnostic yield of 96.5% for cryobiopsy and 93.1% for forceps biopsy with an inverse variance-weighted OR of 1.61 (95% CI, 0.71-3.66) and an I2 of 16%. No instances of moderate to severe bleeding were reported with cryobiopsy. A funnel plot illustrated no major publication bias. CONCLUSIONS Based on analysis of relatively homogenous observational data, pleural cryobiopsy is safe but does not increase diagnostic yield over flexible forceps biopsy. Adequately powered multicenter randomized trials are needed for further investigation.

Abstract
BACKGROUND There is no randomized study comparing pleural cryobiopsy (CB) and flexible forceps biopsy (FFB) in subjects undergoing medical thoracoscopy for the diagnosis of pleural effusions. OBJECTIVE In this crossover study, we compared the diagnostic yield of CB versus FFB in subjects undergoing semirigid thoracoscopy. METHODS Subjects undergoing semirigid thoracoscopy for undiagnosed pleural effusions were subjected to both CB and FFB, with the order of performing the biopsy randomized in a 1:1 ratio. The primary outcome was the diagnostic yield obtained with CB versus FFB. The secondary outcomes included the biopsy size, depth, histologic interpretability, artefacts, the difficulty of performing biopsy on an operator-rated visual analog scale, the severity of bleeding observed at the time of the biopsy, and the duration of the procedure. RESULTS Of the 201 subjects screened, 50 (mean age 52.4 years; 18 women) were included. The diagnostic yield of CB (78.0%) was not different from FFB (76.0%, p = 1.00). CB yielded a larger specimen than FFB (median size 7.0 vs. 4.0 mm; p < 0.001), and a greater depth of specimens (up to the pleural fat or deeper, CB vs. FFB 65.2 vs. 40.8%; p = 0.02). The CB procedure was quicker than FFB (median duration 10 vs. 15 min; p < 0.001). There were no significant differences in the difficulty of performing the biopsy, the severity of bleeding, histologic interpretability, or artefacts in the specimens between the CB and FFB groups. CONCLUSION The diagnostic yield of pleural CB was comparable to FFB during semirigid thoracoscopy.

Abstract
Background The aim of this study was thus to evaluate the feasibility and safety of taking biopsy specimens by cryoprobe from the parietal pleura during semirigid pleuroscope. Methods In a single-center, observational, prospective study, patients with exudative pleural effusion (EPE) were evaluated with a semirigid pleuroscope between January 2015 and July 2017. Each patient underwent pleural biopsy using flexible forceps and flexible cryoprobe through pleuroscope following diagnostic thoracentesis and closed pleural biopsy (CPB). Results A total of 92 patients (median age 64 years) were included in the study, most of whom were men (65.2%). Cytological cell block (CCB) and CPB made definitive diagnoses in 32/92 (34.8%) and 25/92 (27.5%), respectively; flexible forceps biopsy (FFB) and cryoprobe biopsy (CB) established definitive diagnoses in 84/92 (91.3%) and 91/92 (98.9%), respectively. The sample obtained by CB (9.4 ± 4.9 mm) was significantly larger than the other two methods: FFB (4.2 ± 2.3 mm) or CPB (1.9 ± 1.0 mm) (P < 0.0001). The immunohistochemical (IHC) staining was more easily performed with CB (98.9%) compared to either FFB (87.0%) or CPB (13.0%). There were no significant complications or procedure-related deaths. Conclusions Based on these results, CB during semirigid pleuroscope has a high diagnostic yield, differentiating EPE of unknown etiology with satisfactory effectiveness and safety.

Abstract
The burden of a number of pleural diseases continues to increase internationally. Although many pleural procedures have historically been the domain of interventional radiologists or thoracic surgeons, in recent years, there has been a marked expansion in the techniques available to the pulmonologist. This has been due in part to both technological advancements and a greater recognition that pleural disease is an important subspecialty of respiratory medicine. This article summarises the important literature relating to a number of advanced pleural interventions, including medical thoracoscopy, the insertion and use of indwelling pleural catheters, pleural manometry, point-of-care thoracic ultrasound, and image-guided closed pleural biopsy. We also aim to inform the reader regarding the latest updates to more established procedures such as chemical pleurodesis, thoracentesis and the management of chest drains, drawing on contemporary data from recent randomised trials. Finally, we shall look to explore the challenges faced by those practicing pleural medicine, especially relating to training, as well as possible future directions for the use and expansion of advanced medical interventions in pleural disease.

Abstract
PURPOSE OF REVIEW Due to the increasing burden of pleural diseases worldwide, a personalized cost-effective management of these conditions is essential to optimize the healthcare sources. The current review is focused on latest evidence in diagnostic work-up and management of pleural diseases. RECENT FINDINGS Recent research highlights the increasing role of thoracic ultrasound in both diagnostic and therapeutic interventions and the potential suitability of cytological sampling from pleural effusions for molecular analysis, essential requirement for a satisfactory test in the era of personalized anticancer therapy. The thoracoscopic approach, by means of rigid or semirigid instruments, remains the gold standard, and attractive tools to increase diagnostic yield in semirigid pleuroscopy include insulated-tip diathermic knife and cryprobe. Talc pleurodesis and indwelling pleural catheters are the most effective interventions, and their combination, likely to result in additional benefits, is currently under investigation. SUMMARY Because of the huge variety of possible clinical settings, a proper management of pleural diseases should be tailored on a case-by-case basis and requires a multidisciplinary approach. Recent advances in technologies has conferred to interventional pulmonology an increasing relevant role in this context, leading to the development of a dedicated subspecialty, and training programs are urgently needed to standardize skills and care pathways.

Intra-patient comparison of parietal pleural biopsies by rigid forceps, flexible forceps and cryoprobe obtained during medical thoracoscopy: a prospective series of 80 cases with pleural effusion. BMC Pulm Med 2016; 16:98. [PMID: 27387441 PMCID: PMC4937596 DOI: 10.1186/s12890-016-0258-5] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2016] [Accepted: 06/06/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There is only few data available on the use of cryotechnique during medical thoracoscopy. METHODS Medical thoracoscopy was performed in consecutive patients with pleural effusion. Prospectively, biopsies were taken by rigid forceps, flexible forceps and cryoprobe. Specimen size, depth and diagnostic yield were compared. RESULTS 80 Patients were included. 408 biopsies were taken (205 rigid biopsies, 104 flexible biopsies, 99 cryobiopsies). Mean surface area of rigid biopsies was 22.6 ± 20.4 mm(2) (flexible biopsies: 7.1 ± 9.3 mm(2), cryobiopsies: 14.4 ± 12.8 mm(2)). Rigid biopsies were significantly larger than cryobiopsies (p < 0.001) and flexible biopsies (p < 0.001), crybiopsies were significantly larger than flexible biopsies (p < 0.01). A deep biopsy containing fatty tissue was harvested in 63 % of rigid biopsies (cryobiopsy: 49.5 % flexible biopsy: 39.5 %). In 79/80 cases (98.7 % 95 % CI cannot be calculated) a diagnosis was obtained by rigid biopsy (cryobiopsy: 73/80 cases (91.3 % 95 % CI 86.0 - 96.5 %), flexible biopsy: 74/80 cases (92.5 % 95 % CI 88.6 - 97.4 %)). Diagnostic yield achieved with cryobiopsies was inferior to the yield of rigid biopsies (Difference: 12.7 %), but non-inferior to flexible biopsies (Difference: 6.5 %). CONCLUSION Cryobiopsies in medical thoracoscopy are safe with high diagnostic yield, non-inferior to flexible biopsies with increased tissue quantity and quality. Cryotechnique can develop an important role in medical thoracoscopy in the near future when rigid thoracoscopy is not available.
