Results: Seventyone patients received checking with TPB, all patients could initiativiy go with checking, one patient took place pneumogastric nerve reflect, 4 patients take place hematuria postoperation, 5 patients feel soreness in shortterm. All complications were found in morning, and were cure by nursing and treatment. Conclusion: TPB is valid checking method to occupy lesion of prostate for qualitation. Because TPB is a traumatic operation, homologous nursing measure must be take to improve safety of TPB and quality of care.
ObjectiveTo summarize the current status and advances of sentinel lymph node biopsy (SLNB) technique in breast cancer. MethodsThe pertinent domestic and overseas literatures were reviewed and the localization, harvest, status assessment, indications, and complications of SLNB were analyzed. ResultsSLNB could accurately locate and pick out sentinel lymph node (SLN) in breast cancer. The development on imaging examination and pathological techniques promoted the assessment of SLN, and the indications of SLNB were expanding. The complication rate of SLNB was low and the technique could accurately predict axillary lymph node staging and direct selective axillary lymph node dissection. ConclusionsSLNB has been an important method of surgical therapy in breast cancer, but the operation process needs to be further standardized to decrease the false negative rate. Continuative attentions shall be paid to the problems such as the false positive and controversial indications.
Objective To explore the clinical value of only using blue dye as tracer in the sentinel lymph node biopsy (SLNB) of breast cancer. Methods SLNB was performed with the guidance of the combination of blue dye and isotope in all patients enrolled. SLNB data of blue dye only, and the combination method was recorded respectively for analyses. Results Three hundred and eight patients were enrolled in this prospective study. Significant differences were found in the identification rate (IDR, 93.5% vs. 99.4%, P=0.000), the false negative rate (FNR, 14.8% vs. 3.3%, P=0.007), the accuracy rate (AR, 89.6% vs. 97.8%, P=0.006), and the negative predictive value (NPV, 74.0% vs. 93.3%, P=0.012) between the blue dye alone and the combination method. The IDR and the FNR of the two methods were not significantly associated with the patient age, tumor size and location, histopathological type, type of biopsy and breast surgery, or ER, PR, and HER-2 status (all Pgt;0.05). The FNR of blue dye alone was significantly associated with clinically suspicious turgescence of axillary lymph nodes (P=0.042) and decreased followed by the increased number of sentinel lymph nodes obtained (P=0.000). Conclusions Compared with the combination method, SLNB guided with blue dye alone had significantly poorer IDR, AR, and NPV, and higher FNR. It is recommended that the combination of dye and isotope should be adopted for the guidance of SLNB in clinical practice rather than the use of blue dye alone.
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.
ObjectiveTo review the recent studies about sentinel lymph node biopsy in breast cancer.MethodsThe literatures in recent years on the history, concept, technique and clinical application of sentinel lymph node biopsy were reviewed and summarized.ResultsThere was no unified method for sentinel lymph node biopsy. There was a wide range of detection rate and falsenegative rate.ConclusionProspective multicenter random clinical trials will help to evaluate the clinical application of sentinel lymph node biopsy.
Objective To identify the feasibility of the lymphatic mapping and sentinel node biopsy (SLNB) in patients with breast cancer and to examine whether the characteristics of the sentinel lymph node (SLN) accurately predict the status of axillary lymph node.MethodsFrom March to October 2000, 32 patients with breast cancer were evaluated at the Sichuan Provincial People’s Hospital. Lymphatic mapping was performed using Methlene Blue. A SLN was defined as any blue node. Thirtytwo patients, with breast cancer underwent a complete axillary lymph node resection (ALNR) following SLN biopsy. Subsequently, all SLNs and ALNs were examined by both Hamp;E staining as well as immunohistochemical staining for cytokeratin. ResultsLymphatic mapping was successful in identifying the SLN in 26/32(81.25%) cases of nodes at level Ⅰ. Of the 26 patients mapped successfully, 10 had metastasis to the SLNs.In 3 cases that SLNs were positive, but other axillary lymph nodes were negative. In 2 cases that the SLNs were negative, but other axillary lymph nodes were positive. The sensitivity of SLNB using Methlene Blue in this study was 77.78%(7/9), accuracy 80.77%(21/26), specificity 82.35%(14/17), and false negative rate 22.22%(2/9). ConclusionSLN can predict the status of the axillary lymph nodes reliably. However, the efficacy of SLNB in the setting of randomized, prospective trials must be tested first before abandoning axillary lymph node resection as the standard of care.
Objective To analyze the clinical presentations and radiological characteristics of pathologically proved cases of cryptogenic organizing pneumonia(COP).Methods The clinical and radiological features of 8 patients with COP confirmed by open lung biopsy were analyzed.Treatment and follow-up data were also recorded.Results There were 5 male an 3 female patients aged 37 to 68 years.Dyspnea，cough and inspiratory crackles were the most common symptoms and signs.Various computed tomography findings including ground glass opacities,pathy consolidation with air bronchograms，nodules and reticulation were simultaneously observed in the same patient.The diagnostic imaging features of COP were patchy or lobar consolidation，often by a predominantly subpleural distribution，and irregular band-like opacities distributed along the bronchovascular bundle or located in the subpleural area.All patients were treated with corticosteroids and yielded significant improvement in seven cases.Conclusions COP could be diagnosed by clinical and radiological findings and histopathological examination was needed for confirmed diagnosis.In general，COP responds well to glucocorticoid therapy and has a benign prognosis.
Objective To evaluate the safety and diagnostic yield of transbronchial lung biopsy ( TBLB) performed in mechanically ventilated patients. Methods TBLB was performed in 19 mechanically ventilated patients form January 2001 to September 2007 in the ICU of Guangzhou Institute of Respiratory Diseases. The results of clinical data were retrospectively analyzed. Results A total of 19 patients were analyzed[ 9 female, 10 male, with amean age of ( 57. 94 ±15. 00) years] . Specific diagnoses were made in 9 cases ( 47. 4% ) by TBLB. The diseases included pulmonary aspergillus pneumonia in 4 cases ( 21. 0% ) ,lung cancer in 2 cases ( 10. 5% ) , radioactive pneumonia in 1 case( 5. 3% ) , Goodpasture’s syndrome in1case( 5. 3% ) , pulmonary tuberculosis in 1 case ( 5. 3% ) . Ten cases ( 52. 6% ) were not able to establish confirmed diagnoses including pulmonary interstitial fibrosis in 6 cases( 31. 6% ) and lung tissue nonspecific changes in 4 cases( 21. 0% ) . The treatment was adjusted according to the results of TBLB in 10 patients( 52. 6% ) . Complications associated with this procedure included episodes of bronchial hemorrhage of ≥30 mL in 4 cases ( 21. 0% ) , transient oxygen desaturation in 11 cases ( 57. 9% ) , hypotension in 5 cases ( 26. 3% ) , and transient tachycardia in 1 case ( 5. 3% ) without death and pneumothorax. Conclusions TBLB can be performed safely and has a diagnostic value in mechanically ventilated patients. TBLB should be considered as a diagnostic procedure before open lung biopsy.
Objective To evaluate the complication rate of CT-guided percutaneous lung biopsy and determine the risk factors. Methods A retrospective investigation of patients with CT-guided percutaneous lung biopsy in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine between2002 and 2009 was performed. The risk factors for complications were determined by multivariate analysis of variables related to patients’demographics, lung lesions, biopsy procedures, and individual radiological features. Results 281 biopsy procedures were enrolled. The total complication rate was 55. 9% with pneumothorax 32. 4% ( 91/281) , hemoptysis 34. 5% ( 97 /281) , and cutaneous emphysema2. 1% ( 6 /281) , and with no mortality.The pneumothorax rate was correlated with lesion location, lesion depth, and number of pleural passes. The bleeding risk was correlated with lesion size, lesion depth, and age. Prediction models for pneumothorax and bleeding were deduced by logistic regression. The pneumothorax model had a sensitivity of 80. 0% and a specificity of 62. 4% . And the bleeding model had a sensitivity of 67. 4% and a specificity of 88. 8% .Conclusions Lesion location, lesion depth, and number of pleural passes were independent risk factors for pneumothorax. Lesion size, lesion depth, and age were independent risk factors for bleeding. The prediction models for pneumothorax and bleeding will helpfully reduce the complication of CT-guided lung biopsy.
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.
