Cancers Feb 2024To compare conventional smears (CSs) and liquid-based preparations (LBPs) for diagnosing thyroid malignant or suspicious lesions. (Review)
Review
BACKGROUND
To compare conventional smears (CSs) and liquid-based preparations (LBPs) for diagnosing thyroid malignant or suspicious lesions.
METHODS
Studies in the PubMed, SCOPUS, Embase, Web of Science, and Cochrane database published up to December 2023. We reviewed 17 studies, including 15,861 samples.
RESULTS
The diagnostic odds ratio (DOR) for CS was 23.6674. The area under the summary receiver operating characteristic curve (AUC) was 0.879, with sensitivity, specificity, negative predictive value, and positive predictive value of 0.8266, 0.8668, 0.8969, and 0.7841, respectively. The rate of inadequate specimens was 0.1280. For LBP, the DOR was 25.3587, with an AUC of 0.865. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.8190, 0.8833, 0.8515, and 0.8562. The rate of inadequate specimens was 0.1729. For CS plus LBP, the AUC was 0.813, with a lower DOR of 9.4557 compared to individual methods. Diagnostic accuracy did not significantly differ among CS, LBP, and CS plus LBP. Subgroup analysis was used to compare ThinPrep and SurePath. The DORs were 29.1494 and 19.7734. SurePath had a significantly higher AUC.
CONCLUSIONS
There was no significant difference in diagnostic accuracy or proportion of inadequate smears between CS and LBP. SurePath demonstrated higher diagnostic accuracy than ThinPrep. Recommendations for fine-needle aspiration cytology should consider cost, feasibility, and accuracy.

Review
BACKGROUND AND AIMS
Obtaining adequate tissue samples in subepithelial lesions (SELs) remains challenging. Several biopsy techniques are available, but a systematic review including all available techniques to obtain a histologic diagnosis of SEL is lacking. The aim of this study was to evaluate the diagnostic yield and adverse event rates of endoscopic biopsies, EUS-guided FNA (EUS-FNA), EUS-guided fine-needle biopsy (FNB) (EUS-FNB), and mucosal incision-assisted biopsy (MIAB) for SELs in the upper GI tract.
METHODS
A search strategy in multiple databases was performed. The primary outcome was diagnostic yield, defined as the percentage of procedures in which histology was obtained and resulted in a definitive histopathologic diagnosis. Secondary outcome measures included reported procedure-related adverse events, which were graded according to the AGREE (Adverse Events in Gastrointestinal Endoscopy) classification.
RESULTS
A total of 94 original articles were included. Studies were classified per endoscopic technique to obtain histopathology. This resulted in 8 included studies for endoscopic biopsy methods, 55 studies for EUS-FNA, 33 studies for EUS-FNB, and 26 studies for MIAB. Pooled rates for diagnostic yield were 40.6% (95% confidence interval [CI], 30.8-51.2) for endoscopic biopsy, 74.6% (95% CI, 69.9-78.7) for EUS-FNA, 84.2% (95% CI, 80.7-87.2) for EUS-FNB, and 88.2% (95% CI, 84.7-91.1) for MIAB. Reported procedure-related adverse events graded AGREE II or higher were 2.8% to 3.9% for endoscopic biopsies, 1.0% to 4.5% for EUS-FNA, .9% to 7.7% for EUS-FNB, and 1.9% to 7.9% for MIAB.
CONCLUSIONS
Based on the available evidence, MIAB and EUS-FNB seem to be most effective in terms of achieving a high diagnostic yield, with similar rates of adverse events.

Ovarian tuberculosis is a rare entity with non-specific clinical manifestations, difficult diagnosis, and specific medical management. Ovarian involvement in tuberculosis (TB) may occur in two forms, namely, perioophoritis and oophoritis. The constitutional symptoms of tuberculosis such as anorexia, weight loss, night sweats, and evening rise in temperature have been reported in up to 45% of patients. Misdiagnosis and delayed diagnosis are common. A direct histopathological demonstration is the best diagnostic modality. Fine needle aspiration cytology (FNAC) is the study of choice and polymerase chain reaction (PCR) assay increases its sensitivity. The standard short-course antituberculous for 6 months is recommended for isolated ovarian tuberculosis and for widespread disease, 12 months of therapy is recommended. Surgery is reserved for failure of medical therapy and abscess formation. There are many studies on genito-urinary tuberculosis but a detailed study defining diagnostic studies and management guidelines is still lacking. This article aims to present and share a review of the English-language literature on ovarian tuberculosis to gain a better understanding of etiopathogenesis and diagnostic methods and to provide guidelines for its management.

Meta-Analysis Review
Autologous blood patch intraparenchymal injection reduces the incidence of pneumothorax and the need for chest tube placement following CT-guided lung biopsy: a systematic review and meta-analysis.
PURPOSE
To assess the effectiveness of autologous blood patch intraparenchymal injection during CT-guided lung biopsies with a focus on the incidence of pneumothorax and the subsequent requirement for chest tube placement.
METHODS
A comprehensive search of major databases was conducted to identify studies that utilized autologous blood patches to mitigate the risk of pneumothorax following lung biopsies. Efficacy was next assessed through a meta-analysis using a random-effects model.
RESULTS
Of the 122 carefully analyzed studies, nine, representing a patient population of 4116, were incorporated into the final analysis. Conclusion deduced showed a noteworthy reduction in the overall incidence of pneumothorax (RR = 0.65; 95% CI 0.53-0.80; P = 0.00) and a significantly decline in the occasion for chest tube placement due to pneumothorax (RR = 0.45; 95% CI 0.32-0.64; P = 0.00).
CONCLUSIONS
Utilizing autologous blood patch intraparenchymal injection during the coaxial needle retraction process post-lung biopsy is highly effective in diminishing both the incidence of pneumothorax and consequent chest tube placement requirement.

Meta-Analysis
OBJECTIVES
For diagnosing left adrenal gland metastasis in lung cancer, clinical guidelines recommend to perform EUS, but EUS-B (EUS using an EBUS-scope) is increasingly being used. We evaluated the diagnostic performance of both procedures.
MATERIALS AND METHODS
We did a systematic review (PROSPERO, CRD42023416205) and searched MEDLINE and EMBASE on 04-July-2023 for studies evaluating EUS and/or EUS-B in diagnosing left adrenal gland metastases in adults with (suspected) lung cancer. Outcomes were: (1) ability to visualize the left adrenal gland, (2) ability to sample (in those with successful visualization and in whom sampling was attempted), (3) ability to obtain adequate material (in those with successful sampling), (4) malignancy detection rate (in those with successful sampling), and (5) remaining risk of malignancy (in those with a negative EUS(-B)-FNA and undergoing a reference standard). We performed random-effects meta-analyses.
RESULTS
We included 19 studies (EUS: n = 11, EUS-B: n = 6, both: n = 2), covering 1712 patients. All studies had high (n = 18) or unclear (n = 1) risk of bias (QUADAS-2). Average ability to visualize the left adrenal gland was 0.94 (95 %CI 0.82-0.98; n = 7 studies). Average ability to sample was 1.00 (95 %CI 0.99-1.00; n = 9). Average ability to obtain adequate material was 0.96 (95 %CI 0.93-0.98; n = 18). Average malignancy detection rate was 0.42 (95 %CI 0.34-0.49; n = 18). Remaining risk of malignancy was 0.07 (95 %CI 0.04-0.12; n = 8). Ability to visualize was slightly higher for EUS (0.99; 95 %CI 0.90-1.00) than EUS-B (0.84; 95 %CI 0.70-0.92; p = 0.025), but the other performance characteristics were similar. No major complications were reported.
CONCLUSION
Both EUS and EUS-B have good performance and are safe for left adrenal gland analysis in patients with lung cancer, but the number of high-quality studies is limited and further well-constructed prospective studies are needed.

Meta-Analysis Review
The needle size used in ultrasound-guided percutaneous renal biopsy significantly influences the efficacy and safety of the procedure. The aim of this study is to perform a comparative analysis of 16-gauge and 18-gauge needles for ultrasound-guided percutaneous renal biopsy. This systematic review and meta-analysis included randomized controlled trials and observational studies that compared the outcomes of using 18-gauge and 16-gauge needles for ultrasound-guided percutaneous renal biopsy. The efficacy parameters included a mean number of glomeruli obtained and the number of passes, while the safety parameters focused on the rate of complications. We searched multiple databases, assessed the risk of bias, and conducted statistical analyses using appropriate models. Fifteen studies were included. Compared to the 18-gauge needle, the use of 16-gauge needle for the biopsy was associated with the significantly higher mean number of glomeruli obtained (pooled SMD 0.61, 95%CI: 0.32 to 0.89; < 0.001) and fewer required passes (pooled SMD -0.57, 95%CI: -0.97 to -0.18; = 0.004). No significant difference was observed in the individual safety parameters, including pain, hematuria, need for blood transfusion, major, and minor complications. However, the use of 16-gauge needle was associated with higher odds of total complications (pooled OR 1.57, 95%CI: 1.16 to 2.13; = 0.004). While the 16-gauge needle for ultrasound-guided percutaneous renal biopsy offers improved efficacy in terms of a higher mean number of glomeruli and fewer required passes, it is associated with higher total complications. A judicious needle size selection that would consider patient-specific factors and risk-benefit ratio, is crucial for optimizing patient outcomes.

Digestive Diseases and Sciences Oct 2023Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites.
AIMS
This meta-analysis aimed to assess the safety and efficacy of TJLB in children.
METHODS
A literature search of several databases was conducted from inception to August 2022. Eligible studies reported pediatric patients (< 18 years old) who underwent TJLB. The pooled proportion was analyzed using a random-effects model. This review was registered in PROSPERO (CRD42022354421).
RESULTS
From 921 initial studies screened, eight met the eligibility criteria, with a total of 361 pediatric patients who underwent 374 TJLBs. All eight studies reported pooled rates of technical success at 99.1% (95% CI 0.982, 1.001; I = 0%) and histological adequacy of sampling at 97.5% (95% CI 0.954, 0.995; I = 27.66%). A total of 49 complications were reported across six studies, the most common being bleeding from the entry site (38.78%), fevers for less than 24 h (12.24%), red blood cells transfusion requirement (10.2%), supraventricular tachycardia (8.16%), and pain requiring analgesia (8.16%).
CONCLUSION
Pediatric TJLB demonstrates high rates of technical success and adequate liver core biopsy samples, with a low rate of complications. These results suggest that TJLB is an effective method for diagnostic yield and postprocedural outcomes, especially in patients with preexisting coagulopathies and ascites where percutaneous liver biopsy is contraindicated. Additional studies evaluating larger groups of pediatric patients may provide further support for the use of TJLB in this population.

Meta-Analysis
OBJECTIVE
To compare the effectiveness and safety of percutaneous catheter drainage (PCD) against percutaneous needle aspiration (PNA) for liver abscess.
DESIGN
Systematic review, meta-analysis and trial sequential analysis.
DATA SOURCES
PubMed, Web of Science, Cochrane Library, Embase, Airiti Library and ClinicalTrials.gov were searched from their inception up to 16 March 2022.
ELIGIBILITY CRITERIA
Randomised controlled trials that compared PCD to PNA for liver abscess were considered eligible, without restriction on language.
DATA EXTRACTION AND SYNTHESIS
Primary outcome was treatment success rate. Depending on heterogeneity, either a fixed-effects model or a random-effects model was used to derive overall estimates. Review Manager V.5.3 software was used for meta-analysis. Trial sequential analysis was performed using the Trial Sequential Analysis software. Certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation system.
RESULTS
Ten trials totalling 1287 individuals were included. Pooled analysis revealed that PCD, when compared with PNA, enhanced treatment success rate (risk ratio 1.16, 95% CI 1.07 to 1.25). Trial sequential analysis demonstrated this robust finding with required information size attained. For large abscesses, subgroup analysis favoured PCD (test of subgroup difference, p<0.001). In comparison to PNA, pooled analysis indicated a significant benefit of PCD on time to achieve clinical improvement or complete clinical relief (mean differences (MD) -2.53 days; 95% CI -3.54 to -1.52) in six studies with 1000 patients; time to achieve a 50% reduction in abscess size (MD -2.49 days; 95% CI -3.59 to -1.38) in five studies with 772 patients; and duration of intravenous antibiotic use (MD -4.04 days, 95% CI -5.99 to -2.10) in four studies with 763 patients. In-hospital mortality and complications were not different.
CONCLUSION
In patients with liver abscess, ultrasound-guided PCD raises the treatment success rate by 136 in 1000 patients, improves clinical outcomes by 3 days and reduces the need for intravenous antibiotics by 4 days.

The accuracy of ultrasound-guided fine-needle aspiration and core needle biopsy in diagnosing axillary lymph nodes in women with breast cancer: a systematic review and meta-analysis.
BACKGROUND
This study evaluates the diagnostic accuracy of ultrasound-guided fine needle aspiration (US-FNA) and core needle biopsy (US-CNB) for detecting axillary lymph nodes in women with breast cancer.
METHODS
Eligible studies and pertinent literature resources were identified in Cochrane, PubMed, Embase, CNKI, VIP, and Wanfang databases using subject-specific keywords. Study outcomes were tested for heterogeneity, and meta-analyses were performed to estimate sensitivity, specificity, and diagnostic odds ratios (DORs). The summary receiver operating characteristic (SROC) curve analysis was also performed.
RESULTS
A total of 22 studies involving 3,548 patients were included to evaluate the diagnostic accuracy of US-FNA and 11 studies involving 758 patients were included to evaluate the diagnostic accuracy of US-CNB in identifying axillary lymph nodes in women with breast cancer. The accuracy of US-FNA in identifying suspicious axillary lymph nodes was as follows: overall sensitivity, 79% (95% CI: 73%-84%); global specificity, 96% (95% CI: 92%-98%); overall positive likelihood ratio, 18.55 (95% CI: 10.53-32.69); overall negative likelihood ratio, 0.22 (95% CI: 0.17-0.28); DOR, 71.68 (95% CI: 37.19-138.12); and the area under the SROC curve, 0.94 (95% CI: 0.92-0.96). The accuracy of US-CNB in identifying suspicious axillary lymph nodes was as follows: overall sensitivity, 85% (95% CI: 81%-89%); global specificity, 93% (95% CI: 87%-96%); overall positive likelihood ratio, 11.88 (95% CI: 6.56-21.50); overall negative likelihood ratio, 0.16 (95% CI: 0.12-0.21); overall DOR, 66.83 (95% CI: 33.28-134.21), and the area under SROC curve 0.96 (95% CI: 0.94-0.97).
CONCLUSIONS
The results indicate that both US-FNA and US-CNB have high accuracy for suspicious axillary lymph nodes.

Review
Scirrhous gastric cancer (SGC) is diagnosed using endoscopy and/or biopsy; however, SGC diagnosis remains challenging owing to its special growth form and morphologic features. Hence, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), which is minimally invasive and has a high proportion of diagnostic tissue, may be an alternative investigative modality for patients with suspected SGC. This systematic review and meta-analysis aimed to identify and evaluate the evidence for the efficacy and safety of EUS-FNA in patients with suspected SGC. We conducted a systematic review using the PubMed (MEDLINE) and Ichushi-Web (NPO Japan Medical Abstracts Society) databases and included all entries in which SGC was evaluated using EUS-FNA in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from the databases' inception to October 10, 2022. The primary outcome was the proportion of SGC diagnosed using EUS-FNA. In addition, we analyzed the proportion of adverse events associated with EUS-FNA. The electronic search identified 1890 studies; overall, four studies met the selection criteria and reported data on EUS-FNA performed on 114 patients with suspected SGC. The overall diagnostic yield of EUS-FNA for SGC was 82.6% (95% confidence interval, 74.6-90.6%) and the statistical heterogeneity was 0% ( = 0%), indicating a low heterogeneity. Furthermore, the EUS-FNA diagnostic proportion for SGC lymph node metastasis was 75-100%, indicating a high diagnostic performance. The adverse event rate of EUS-FNA was 0%. EUS-FNA may be an alternative investigation mode for SGC patients with negative esophagogastroduodenoscopy-biopsy results.
