上腔静脉阻塞综合征多由于右肺上叶癌或右上纵隔肿瘤肿块较大时压迫上腔静脉(SVC)及左右无名静脉所致。使用体外循环或非体外循环方法行肿瘤切除和SVC置换既可切除肿瘤又可解除SVC的阻塞,但是非体外循环下上腔静脉置换术的麻醉具有一定的挑战性。笔者于2000~2005年为9例在非体外循环下阻断SVC行肿瘤切除及SVC移植术的上腔静脉患者成功地进行了麻醉,现报告如下。 相似文献

The main indications for cervical mediastinoscopy are preoperative staging of lung cancer and diagnostic biopsy of mediastinal mass (lymphoma, sarcoidosis, tuberculosis etc.). We undertook a retrospective review of our experience of mediastinal exploration by cervical media-stinoscopy: 253 mediastinoscopies were performed on 252 patients (195 male and 57 female; mean age 53 years, range 14-88 years) between 1995 and June 2003. Four extended mediastinoscopies were performed and 1 patient had a re-mediastinoscopy following a non-diagnostic procedure. 319 lymph nodal stations were investigated in 253 procedures. We observed no mortality, while 2 patients had major bleeding (0.7%), with the need for open surgical treatment in order to achieve haemostasis. The median length of hospital-stay was one day, with discharge in the first postoperative day. 69 out of 170 patients, who eventually resulted to be affected by a histologically proven lung cancer, had a negative mediastinoscopy. Fifteen of them resulted N2 at the time of surgery: 8 patients with a false negativity in a biopsied station (4 in station 4R and 4 in station 7), while 7 cases showed infiltration in stations which were not sampled (5 in station 5, 1 in station 8 and 1 in station 7, the latter being the only one in which a standard cervical mediastincoscopy could have been able to stage it correctly). So, having observed 61 true negatives and 8 false-negatives in the sampled stations, in our experience the negative predictive value of cervical mediastinoscopy was 88.4%, with 78.2% of patients correctly staged without using other diagnostic tools. In conclusion, mediastinoscopy is an important procedure for the diagnostic biopsy of mediastinal mass and a useful tool in preoperative staging of lung cancer, especially if associated with chest CT-scan and Positron Emission Tomography (PET). In our experience, the spreading of PET does not lead to a reduction of cervical mediastinoscopies, both for the contemporary introduction of new chemotherapeutic preoperative protocols and, above all, for the not negligible incidence of false-positive results using PET, suggesting that media-stinoscopy should always be performed in patients affected by a PET-positive mediastinal growth. 相似文献

OBJECTIVE: Mediastinoscopy is a common procedure used for the diagnosis of thoracic disease and the staging of lung cancer. We sought to determine the current role of mediastinoscopy in the evaluation of thoracic disease. METHODS: We conducted a retrospective review of all mediastinoscopies performed by members of our service between January 1988 and September 1998. RESULTS: We performed mediastinoscopies on 2137 patients. A total of 1745 patients underwent mediastinoscopy for known or suspected lung cancer. In 422 of these procedures, N2 or N3 disease was identified; only 28 of these patients underwent resection. The remaining 1323 had no evidence of metastatic disease. In these patients 947 had lung cancer. Only 76 of the patients with lung cancer were found to have N2 disease at exploration. Among the 1323 patients with a negative mediastinoscopy result, 52 underwent resection of a nonbronchogenic malignancy, and 217 had resection of a benign lesion. A total of 392 patients underwent mediastinoscopy for the evaluation of mediastinal adenopathy in the absence of any identifiable pulmonary lesion. Of these, 161 had a nonbronchogenic malignancy, 209 had benign disease, and 25 had no diagnosis established; mediastinoscopy established a definitive diagnosis in 93.6% of patients. In the entire group of 2137 patients, there were 4 perioperative deaths and 12 complications. Only one death was directly attributed to mediastinoscopy. No deaths or complications occurred in patients undergoing mediastinoscopy for benign disease. CONCLUSIONS: Mediastinoscopy is a highly effective and safe procedure. We believe that mediastinoscopy should currently be used routinely in the diagnosis and staging of thoracic diseases. 相似文献

Six hundred and eighty diagnostic mediastinoscopies are presented. Of these, 552 were classical, 114 anterior mediastinal, 12 posterior mediastinal, and 2 from below the sternum. In addition, 20 therapeutic mediastinoscopies were performed for the insertion of a pacemaker electrode or evacuation of a mediastinal cyst.Of 125 mediastinoscopies performed on patients with an initial diagnosis of sarcoidosis, in most the diagnosis was confirmed, the rate of false negative results being 2·4%.Extremely encouraging were the results in patients with an initial diagnosis of Hodgkin''s disease. Out of 60 patients, a different diagnosis was established in 30 and further follow-up proved this to be correct. In mediastinal tumours the results were discouraging, the rate of false results being as high as 43%.Four hundred and ten patients were mediastinoscoped for lung cancer. In 52, mediastinoscopy was the first successful biopsy. Metastases to lymph nodes were found in 139 (33·9%). The percentage of exploratory thoracotomies following the introduction of mediastinoscopy fell from 22% to 14%.Mediastinoscopy was also used to investigate the spread of oesophageal cancer and enabled us to exclude patients who were obviously inoperable. 相似文献

BACKGROUND: Although transthoracic needle biopsy (TNB) has been the preferred method for the diagnosis of anterior mediastinal masses, it has inherent limitations in accuracy. In particular, lymphoma and thymoma are diagnosed less reliably using needle biopsy. Videothoracoscopy has been advocated as an alternative method for diagnosis. Our goal was to assess the usefulness of extended cervical mediastinoscopy (ECM) in the diagnosis of anterior mediastinal masses. METHODS: The ECM technique was performed in 9 patients in whom TNB and Tru-cut biopsies had been inefficient for histologic diagnosis. All lesions were in the anterior mediastinum. Extended cervical mediastinoscopy was carried out using the same incision as in a standard cervical mediastinoscopy and dissection was performed behind the sternum as previously published. Mean operative time was 50 minutes (range 40 to 70 minutes) and mean hospital stay was 8 hours (range 5 to 36 hours). RESULTS: Diagnosis of lymphoma in 4 cases, thymoma in 3 cases, and thymic hyperplasia in 2 cases were obtained by ECM. In 1 of 2 patients with suspected thymoma who underwent resectional surgical procedures, final histologic diagnosis was non-small cell lung carcinoma. There was no surgical mortality or intraoperative complication. One patient had minimal pneumothorax requiring no intervention. CONCLUSIONS: We conclude that ECM in the diagnosis of anterior mediastinal masses is technically feasible and provides an alternative to the conventional approaches in patients with paraaortic or aortopulmonary masses. 相似文献

OBJECTIVE: Despite new technologies, mediastinoscopy remains the gold standard for mediastinal staging of lung cancer even though the procedure is not standardised. Introduction of video-mediastinoscopy (VM) may help to overcome this problem as it better visualises the anatomy and allows a more uniform dissection than conventional mediastinoscopy (CM). Does the use of VM result in more lymph node tissue, higher accuracy and lower complication rates as compared to CM? METHODS: All mediastinoscopies from June 2003 to December 2005 were analysed. In a protocol surgeons documented location of lymph node stations, number of lymph nodes resected or biopsied and technique (VM or CM). Two groups were created for analysis: group 1 (n=366) consisting of all mediastinoscopies was reviewed for complication rates; group 2 included all patients with lung cancer who had a pN0 status by mediastinoscopy and underwent subsequent thoracotomy (n=171). This group was studied for the number of lymph nodes resected or biopsied according to the technique (VM or CM), on accuracy and negative predictive value. RESULTS: Of 366 mediastinoscopies, 132 were CM (36.1%) and 234 VM (63.9%). Complications occurred in 17 patients (4.6%): 9 recurrent laryngeal nerve palsies (VM 2.1%, CM 3.0%), 5 mediastinal enlargement on routine chest radiography interpreted as postoperative bleeding (VM 0.9%, CM 2.3%), pneumonia (1), intraoperative laceration of the pleura (1) and main bronchus (1), both corrected during the procedure (all VM 1.3%). No intraoperative haemorrhage or death occurred. VM resected more lymph nodes (mean 8.1, range 3-25) then CM (mean 6.0, range 3-11), for all mediastinoscopies the mean lymph node yield was 7.6 (range 3-25). Comparison of lymphadenectomy via thoracotomy in patients classified pN0 by mediastinoscopy (n=171) showed an accuracy of 87.9% for VM versus 83.8% for CM (85.8% for all mediastinoscopies) with a negative predictive value of 0.83 for VM and 0.81 for CM (0.82 for all mediastinoscopies). CONCLUSION: This study demonstrates that in comparison with CM, VM routinely yields more lymph nodes with fewer complications with a tendency towards better accuracy and negative predictive value. For these reasons, we believe that VM should replace CM as the method of choice. Furthermore VM would allow standardisation, thereby having an advantage in comparison to the less invasive newer staging techniques. This way mediastinoscopy could remain the gold standard despite its invasiveness. 相似文献

BACKGROUND: The diagnostic and staging value of cervical mediastinoscopy is well established. Left anterior mediastinotomy is of further value in assessing left upper lobe tumors. However the efficacy and safety of both these procedures after median sternotomy for cardiac surgery is unknown. METHODS: We undertook a retrospective review of our experience of mediastinal exploration by cervical mediastinoscopy with or without left anterior mediastinotomy in patients with prior sternotomy between 1980 and 2001. RESULTS: During this period 28 patients (25 male and 3 female; mean age, 63 +/- 10 years), all with prior sternotomy for cardiac surgery (14 had left internal mammary artery graft), underwent mediastinal exploration. The mean interval between sternotomy and mediastinal exploration was 7.2 +/- 5.1 years. Additionally, 3 patients also had superior vena cava obstruction. Cervical mediastinoscopy was performed in all 28 patients and additionally left anterior mediastinotomy was undertaken in 7 of 28 patients (4 with left internal mammary artery graft). Indications for exploration were staging of lung cancer in 22 patients (cervical mediastinoscopy, n = 22; left anterior mediastinotomy, n = 7) and diagnostic biopsy of mediastinal mass in 6 patients (cervical mediastinoscopy, n = 6). Thorough mediastinal assessment was possible in all 28 patients. In the 22 patients with lung cancer the median number of lymph node stations sampled during mediastinoscopy was 3 (range, 1 to 5). A specific diagnosis was obtained in 16 patients (metastatic lung cancer, n = 10; lymphoma, n = 3; sarcoidosis, sinus histiocytosis, and metastatic melanoma, n = 1 each). The other 12 patients with negative findings underwent pulmonary resection and only 1 of 12 (8%) patients had unexpected N2 disease, a similar proportion to our overall experience with lung cancer. There were no operative complications. CONCLUSIONS: Prior sternotomy for cardiac surgery does not compromise the efficacy and the safety of mediastinoscopy and mediastinotomy. 相似文献

With the advent of modern therapy, it has become essential to obtain a tissue diagnosis in all cases of pulmonary and mediastinal disease. Since it is often necessary to resort to thoracotomy as a final step in making such a diagnosis, we have sought a procedure that is simpler while capable of providing the same information.Through a standard cervical mediastinoscopy incision, the mediastinum is first explored; if the diagnosis is not obtained, the mediastinal pleura is digitally opened and lung or pleural biopsies are taken. In the course of 1,100 mediastinoscopies since 1969, 275 pleuroscopies have been done. We were able to obtain a tissue diagnosis in 102 (78%) of 131 patients with bronchogenic carcinoma, in 92 (91%) of 102 with benign pulmonary disease, and in all 20 (100%) with pleural disease. 相似文献

Objective: To evaluate the diagnostic yield, the learning curve and the safety of endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) in mediastinal staging of patients with lung cancer. Methods: Mediastinal staging was performed with EBUS-TBNA according to the Danish national guidelines in patients fulfilling one or more of the following criteria: (1) central tumour; (2) enlarged (>10 mm) mediastinal lymph nodes on computed tomography; or (3) positron emission tomography (PET)-positive mediastinal lymph nodes. The study period began in January 2006 when EBUS-TBNA was introduced in the department and ended in December 2007. All records were reviewed retrospectively. None of the four examiners had any previous experience with EBUS-TBNA or ultrasound when the study began. All examinations were performed under general anaesthesia. Patients without useful cytological material from the EBUS-TBNA were subjected to a supplementary standard cervical mediastinoscopy if the mediastinal lymph nodes were found to be enlarged (>10 mm), PET positive or if the examiner was insecure of the result of the EBUS-TBNA. Patients with mediastinal lymph node involvement, detected by EBUS-TBNA or standard cervical mediastinoscopy, were referred to oncological treatment, while those without mediastinal lymph node involvement underwent – if they were otherwise eligible for surgery – resection and systematic lymph node sampling either by thoracotomy or by video-assisted thoracoscopy. Final mediastinal staging was defined as positive if mediastinal lymph node involvement was detected by EBUS-TBNA, standard cervical mediastinoscopy or surgery, or defined as negative otherwise. Results: A total of 157 patients were included in the study. N2/N3 disease was found in 67 patients (42.6%). EBUS-TBNA missed the mediastinal spread in 10 patients. Five of the ten patients had lymph node metastases in station 5, 6 or 8 – out of reach of EBUS-TBNA or standard cervical mediastinoscopy. EBUS-TBNA had a sensitivity of 0.85 (0.74–0.93) and a negative predictive value of 0.90 (0.82–0.95). No complications occurred from EBUS-TBNA. The number of supplementary standard cervical mediastinoscopies decreased significantly in the study period. Conclusion: The results of this study suggest that staging of the mediastinum with EBUS-TBNA is safe and easy to learn – even without previous experience with ultrasound. The diagnostic yield of EBUS-TBNA is in accordance with the yield of standard cervical mediastinoscopy reported in the literature. We do not find any indications in the present study of the recommended necessity for mediastinoscopy in all EBUS-TBNA-negative patients. 相似文献

From 1976 to 1990, 140 patients (mean age, 66 years; 91% male) underwent repeat mediastinoscopy as a routine staging procedure. The mean interval between first and second mediastinoscopy was 56 months. Owing to adhesions, 26 repeat mediastinoscopies (18%) were considered incomplete. There was no mortality, and 10 complications did not require interventional therapy. The results were positive in 20 patients, thus avoiding an unnecessary thoracotomy. In 7 patients with negative findings, positive lymph nodes were found at thoracotomy or by transcarinal puncture biopsy. The sensitivity of repeat mediastinoscopy in this series is 74%, and the accuracy 94%. We consider repeat mediastinoscopy a safe and reliable preoperative staging procedure in new or recurrent lung cancer. 相似文献

Mediastinoscopy in superior vena cava obstruction: analysis of 80 consecutive patients. 总被引:14,自引:0,他引:14
BACKGROUND: Prejudices against mediastinoscopy in superior vena cava obstruction still remain. Hereby we analyze risk/benefit balance in a large series of patients. METHODS: Eighty consecutive patients underwent cervical mediastinoscopy for caval obstruction, 51 after uncertain diagnosis obtained by lesser techniques, 17 after ineffective chemotherapy (n = 9) or radiotherapy (n = 8). In 12 patients we immediately performed mediastinoscopy as an urgent procedure. In addition the examination was combined with left anterior mediastinotomy (n = 7) for staging purposes. RESULTS: No perioperative mortality was recorded. Five patients had significant bleeding, but only one required sternotomy. Definitive diagnosis was obtained in all patients: 50 lung cancer, 17 lymphoma, 7 invasive thymoma, 3 postradiation fibrosis, 2 metastatic lymph nodes from renal carcinoma, and 1 fibrosing mediastinitis. Specific therapy had excellent effects in 71 patients, negligible in 7, and adverse in 2. Postmediastinoscopy brachial venous pressure had a mean significant decrease (p < 0.0001). Lung cancer was the sole variable significantly associated with unfavorable outcome (p < 0.0004). CONCLUSIONS: Mediastinoscopy should be routinely included after less invasive procedures in the diagnostic program because it is simple, low risk, and effective. 相似文献
