ObjectiveTo compare the diagnostic accuracy, sampling satisfaction, and safety of ultrasound-guided core needle biopsy (CNB) and fine needle aspiration biopsy (FNA) for thyroid nodules.MethodsThe databases of PubMed, Medline, Web of Science, Cochrane Library, Wanfang, CNKI, and CBM were searched to collect the relevant studies on the diagnostic performance, sampling satisfaction, and safety of ultrasound-guided CNB and FNA for thyroid nodules. Revman 5.3 and Stata 15 software were used for meta-analysis.ResultsA total of 24 studies involving 25 388 patients were included. Meta analysis showed that: compared with CNB, FNA had poor diagnostic accuracy ［OR=0.26, 95%CI (0.15, 0.46), P<0.000 01］, poor sampling satisfaction ［OR=0.20, 95%CI (0.12, 0.33), P<0.000 01］, lower incidence of total complications ［OR=0.28, 95%CI (0.16, 0.50), P<0.000 1］, and lower incidence of bleeding after biopsy ［OR=0.62, 95%CI (0.48, 0.81), P=0.000 3］. However, there was no significant difference in the pain score ［WMD=–0.21, 95%CI (–0.57, 0.15), P=0.26］ between the two groups. Subgroup analysis showed that there was no significant difference in the accuracy of biopsy diagnosis of thyroid nodules with diameter less than 10 mm between the two groups ［OR=0.52, 95%CI (0.15, 1.81), P=0.30］, however, the accuracy of CNB in the diagnosis of thyroid nodules with diameter ≥ 10 mm was still better than FNA ［OR=0.26, 95%CI (0.12, 0.56), P=0.000 5］.ConclusionsCompared with FNA, ultrasound-guided CNB has a certain advantages in sampling satisfaction and the diagnosis accuracy of thyroid nodules with diameter ≥ 10 mm. CNB is better than FNA, but will bring higher risk of complication.
ObjectiveTo explore the application value of synchronous CT-guided percutaneous biopsy followed by radiofrequency ablation in the diagnosis and treatment of lung tumors. MethodsThe clinical data of 21 patients with lung tumors were retrospectively analyzed. There were 8 males and 13 females aged 68 (51, 73) years. A total of 24 lesions underwent CT-guided percutaneous biopsy and concurrent radiofrequency ablation. The effectiveness and safety of this protocol were analyzed. ResultsAll 21 patients successfully completed the procedures. The diameter of 24 lesions was 17.0 (13.3, 19.0) mm. Biopsy specimens met the requirements of pathological diagnosis, and the effectiveness of specimens was 100.0%. The incidence of small amount of pneumothorax/pleural shrinkage after procedures was 19.0% (4/21) and the incidence of tension pneumothorax was 4.7% (1/21). There was no obvious bleeding or other complications.ConclusionSynchronous CT-guided percutaneous biopsy followed by radiofrequency ablation combines two interventional techniques, which is safe and effective in the diagnosis and treatment of lung tumors, and it is worthy of popularization and application in clinic.
Objective To evaluate the diagnostic value and safety of surgical lung biopsies ( SLB)in patients with interstitial lung disease ( ILD) . Methods A retrospective analysis was performed on patients undergoing SLB, who were obtained from Chinese literatures through searching PubMed, CBM,Wanfang database, VIP information and CHKD from 2000 to 2010. The data from Affiliated Drum Tower Hospital, Nanjing University Medical College from2000 to 2010 was also reviewed. Results A total of 398cases underwent SLB, including open lung biopsy ( OLB) in 221 cases and video-assisted thoracoscopic lung biopsy ( VATLB) in 177 cases. SLB yielded a specific diagnosis for 386 cases. The total postoperative complication rate was 12. 1% and mortality rate was 2. 0% . The diagnostic yield, post-operative complication rate, and mortality rate between VATLB and OLB had no significant difference. Conclusion SLB is a useful and relatively safe procedure for diagnosis of ILD.
ObjectiveTo explore the clinical effect of the whole-course integrated care and traditional nursing in perioperative period of percutaneous needle biopsy.
MethodsA total of 198 patients treated between May 2012 and March 2013 were randomly divided into the traditional care group (control group) and the whole-process integrated care group (experimental group). Then, we compared between the two groups in terms of pain and anxiety levels, qualified rate of specimen and incidence of postoperative complications.
ResultsQualified rate of specimen in the experimental group (97.94%) was significantly higher than that in the control group (85.15%) (χ2=10.312, P=0.001). After surgery, the rates of pneumothorax and bleeding were 3.09% and 4.12% in the experimental group, and 11.88% and 14.85% in the control group; the pain score of the experimental group was 4.25±1.38, and 6.12±1.87 in the control group. One hour before and 8 hours after surgery, the anxiety scores were 11.16±3.29, 8.47±2.52 in the experimental group, respectively, and were 16.26±3.17, 12.12±3.26 in the control group, respectively. There were significant differences between the two groups in all the above indexes (P<0.05).
ConclusionWhole-course integrated care can significantly reduce pain and anxiety levels and the incidence of postoperative complications and improve the success rate of percutaneous needle biopsy.
ObjectiveTo investigate the metastatic status and risk factors of axillary non-sentinel lymph node (NSLN) in breast cancer patients with 1–2 positive sentinel lymph nodes (SLN), and to provide theoretical basis for exemption of axillary lymph node dissection (ALND) in these patients. Methods A retrospective analysis was performed on 54 patients diagnosed with breast cancer who underwent sentinel lymph node biopsy (SLNB) and confirmed to have 1–2 positive sentinel lymph nodes (SLNS) and received ALND in the Department of Thyroid and Breast Surgery of Tongling People’s Hospital from January 2018 to April 2023. The patients were divided into NSLN metastatic group (17 cases) and NSLN non-metastatic group (37 cases) according to whether there was metastasis. Chi-square test was used to compare the basic information and clinicpathological features of the two groups. The independent risk factors for axillary NSLN metastasis were screened out by multivariate binary logistic regression model. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of independent risk factors combined with axillary NSLN metastasis. Results There were 54 cases with 1–2 metastasis of SLN, 17 cases with axillary NSLN metastasis (31.5%). The incidence of axillary NSLN metastasis in patients with tumor at T1 stage (maximum diameter ≤2 cm) was only 14.3% (4/28), however, the metastatic rate of axillary NSLN in patients with tumor in T2–T3 stage (maximum diameter >2 cm) was as high as 50.0% (13/26). The axillary NSLN metastasis rate was only 21.2% (7/33) with 1 SLN metastasis, while the axillary NSLN metastasis rate was 47.6% (10/21) with 2 SLN metastasis. Univariate analysis showed that T stage (tumor diameter >2 cm), 2 SLN metastases, number of SLN >5 and tumor with vascular embolus were more likely to develop axillary NSLN metastases (P<0.05). Multivariate binary logistic regression analysis showed that T stage (tumor diameter >2 cm) and 2 SLN metastases were independent risk factors for axillary NSLN metastasis in breast cancer patients, the area under ROC curve of combined prediction of axillary NSLN metastasis by the two was 0.747, 95%CI was (0.657, 0.917), sensitivity was 0.765 and specificity was 0.649. Conclusions The combination of tumor T stage and the number of SLN metastases can better predict axillary NSLN metastasis in breast cancer patients. ALND is recommended for breast cancer patients with T stage (tumor diameter >2 cm) and 2 SLN metastases to reduce the risk of residual axillary NSLN metastasis.
Objective To explore the value of pathologic diagnosis for pancreatic head mass by using recise Tru-cut biopsy under intraoperative ultrasound guided. Methods Twenty-eight patients with solid pancreatic masses in People’s Hospital of Suqian，Affiliated Hospital Xuzhou Medical College from August 2010 to August 2011 were performed precise Tru-cut biopsy under intraoperative ultrasound guided. In all patients of 28 cases, male 20 cases and female 8 cases, the male-to-female ratio was 5∶2. The patients’ age was 34-78 years old（mean age： 64 years old）. Twenty-eight patients were divided into three groups based upon the greatest dimension of the masses as follows：equal or less than 1.5 cm （group S, 5 cases）, 1.5-3.0cm （group M, 7 cases）, and greater than 3.0cm （group L, 16 cases）. Three needlepasses in each mass were performed. The results of postoperative pathologic findings were compared with specimens in paraffin sections. Results In all cases of 28, the diagnostic coincidence rate was 100%, there were no false positive finding and false negative. The coincidence ratio for pathological diagnosis of tissues with only 1 strip sample （1/3）, only 2 strip samples （2/3）, and with 3 strip samples （3/3） were 3/5, 2/5, and 0/0, respectivly in S group, 0/0, 5/7, and 2/7, respectivly in M group, and 0/0, 4/16, and 12/16, respectivly in L group. The false negative rate of single strip sample in S group and M group was higher than that in L group （χ2=9.833，P=0.002）. There was false negative finding with master single test in small focus of infection. Conclusion Precise Tru-cut biopsy under intraoperative ultrasound guided is a safe and highly accurate method for pathological diagnosis of patients with solid pancreatic lesions, especially in small lesions，it is worthy of clinical application..
ObjectiveTo explore the clinicopathological features of pulmonary alveolar proteinosis (PAP).MethodsA total of 25 patients with PAP who were pathologically diagnosed in West China Hospital of Sichuan University from 2014 to 2018 were collected as the study subjects.ResultsThe 25 patients with PAP were 18–73 years old, with an average age of (42.52±15.79) years. There were 20 males and 5 females. The most common type was autoimmune PAP (15 cases), and secondary PAP (10 cases) were found in patients with pneumonia, tuberculosis, nephrotic syndrome, and pneumoconiosis. The common clinical symptoms of PAP were cough (24 cases), expectoration (20 cases), and progressive difficulty in breathing (11 cases of shortness of breath and 5 cases of dyspnea). The chest CT manifestations included double lung grinding (19 cases), grid-like changes (11 cases), and map-like changes (3 cases). Periodic acid-schiff (PAS) staining and post-digestion PAS staining double positive lipoprotein-like deposits was observed in lung biopsy (in the alveolar cavity) and/or alveolar lavage fluids.ConclusionsPAP has no characteristic clinical symptoms and a long diagnosis period. Clinicians should combine clinical signs, imaging features, and lung biopsy and/or alveolar lavage fluid PAS staining and post-digestion PAS staining to confirm the diagnosis.
ObjectiveTo analyze the clinical manifestations and pathological patterns of renal diseases requiring percutaneous renopuncture, evaluate the clinical significance of renal biopsy and the value of clinical pathway for renal biopsy.
MethodsWe retrospectively summarized and analyzed the clinical and pathological data, and the clinical pathway implementation of 224 patients who underwent renal biopsy between October 2009 and September 2014.
ResultsIn the 224 patients, there were 62 cases of IgA nephropathy (27.68%), 50 cases of minimal change nephropathy (22.32%), 28 cases of lupus nephritis (12.5%), 26 cases of membrane nephropathy (11.6%), 26 cases of mesangial proliferative glomerulonephritis (11.6%), 6 cases of purpura nephritis (2.68%), 4 cases of focal segmental glomerular sclerosis (1.79%), 4 cases of hepatitis B virus-associated membrane nephropathy (1.79%), 4 cases of nodular diabetic glomerulosclerosis (1.79%), 4 cases of acute tubulointerstitial nephropathy (1.79%), 2 cases of hypertensive renal damage (0.89%), 2 cases of membrano-proliferative glomerulonephritis (0.89%), 1 case of lipoprotein kidney disease (0.45%), and 1 case of fibrillary glomerulopathy (0.45%). A total of 220 specimens in the 224 cases were qualified, accounting for 98.21%. Diagnosis of 70 patients in the qualified 220 cases were re-corrected according to their renal pathology reports, accounting for 31.81%. In the 224 cases, there were 16 cases of gross hematuria (7.14%) and 24 of peri-renal hematoma (10.71%) after renal biopsy. Patients who met the requirement of clinical pathway were divided into clinical pathway group and control group randomly. Average hospitalization time of the clinical pathway group was (7.6±1.2) days, and the average cost was (5 860±237) yuan, both lower than the control group [(11.8±2.3) days, (7 658±360) yuan)]. The difference was statistically significant.
ConclusionsIgA nephropathy is the most common pathological type of primary glomerular diseases, and minimal change nephropathy the second. Lupus nephritis, membranous nephropathy, mesangial proliferative glomerulonephritis are still the most common types of glomerular diseases. Lupus nephritis becomes the first secondary glomerular disease. Ultrasound guided percutaneous renal biopsy is safe and has high success rate and high clinical application value. The implementation of clinical pathway can shorten the average length of hospital stay and reduce the average hospital cost.
ObjectiveTo investigate the differences between indocyanine green (ICG) plus methylene blue and radioactive nuclide plus methylene blue for sentinel lymph node biopsy (SLNB) after Neoadjuvant chemotherapy (NAC) in breast cancer patients. Methods A total of 77 breast cancer patients who accepted SLNB and axillary lymph node dissection (ALND) after NAC from June 2017 to February 2019 were involved, among them, 46 breast cancer patients accepted SLNB by ICG plus methylene blue and 31 breast cancer patients accepted SLNB by radioactive nuclide plus methylene blue, pathological and clinical data were collected and analyzed.ResultsThere were 43 patients in the ICG plus methylene blue group and 30 patients in radioactive nuclide plus methylene blue group, which totally 73 patients were detected at least one sentinel lymph node in all the 77 patients, and the detection rate was 94.80%. The SLN detected rate, SLN detected numbers, sensitivity, false negative rate, and accuracy of the ICG plus methylene blue group were 93.48% (43/46), 2.32 per case, 82.61% (19/23), 17.39% (4/23), and 90.70% (39/43) respectively, as well as 96.77% (30/31), 2.6 per case, 83.33% (10/12), 16.67% (2/10), and 93.33% (28/30) in the radioactive nuclide plus methylene blue group. There was no significant difference between the ICG plus methylene blue group and radioactive nuclide plus methylene blue group in terms of SLN detected rate, SLN detected numbers, sensitivity, false negative rate, and accuracy (P>0.05).ConclusionICG plus methylene blue showed similar SLN detection rate, SLN detected numbers, sensitivity, false negative rate, and accuracy as radioactive nuclide plus methylene blue for SLNB in breast cancer patients after NAC, and both of them can be performed easily and conveniently.
Objective To investigate the roles of cell apoptosis and the gene expressions of Fas, FasL, bcl-2 and bax in acute rejection of pancreaticoduodenal transplantation and to evaluate the function of duodenum biopsy for early detection of rejection in rats. Methods Wistar and SD rats were divided into two groups: ①Wistar rats that underwent allogenic pancreaticoduodenal transplantation from the organs of SD rats; ②Wistar rats that received homogenic transplantation. The grafts were then harvested on day 3, 5 and 7 after the transplantation, and all graft samples were observed with HE staining and TUNEL was also used to detect apoptotic cells. The expressions of Fas, FasL, bcl-2 and bax were measured by immunochemical method. According to Nakhleh’s score, pathologic features of transplanted pancreas and duodenum were ranged from one to three scores in order. Results The percentage of same or different scores between the pathological scores of pancreas and duodenum in allogenic pancreaticoduodenal transplantation group were 61.1% (11/18) and 38.9% (7/18) respectively, and there were 6 specimens of pancreatic tissue got higher scores with only one higher score for duodenum. There were significant differences of histopathologic rejection scores and apoptotic indices between the two groups, respectively (P＜0.05， P＜0.01). Apoptotic indices of pancreas and duodenum both showed positive correlations with histopathologic rejection scores (r=0.965， P＜0.01; r=0.942, P＜0.01). The rejection score and apoptotic index elevated, the expression of FasL increased, bcl-2 decreased, and Fas and bax changed over time after operation. Conclusion Apoptosis maybe significantly positive correlated with the degrees of damage of the acute pancreaticoduodenal allograft rejection, and the apoptotic index maybe valuable to estimate the damage. FasL and bcl-2 were significantly related to the impairment of acute pancreatic allograft rejection as well. Duodenum biopsy may contribute to the early diagnosis of the rejecting transplanted tissues.
