ABSTRACT

Objective To investigate the risk factors and clinical prognosis of massive blood transfusion during the perioperative period of lung transplantation. Methods Clinical data of 159 lung transplant recipients were retrospectively analyzed. According to the quantity of perioperative blood transfusion, all recipients were divided into the massive blood transfusion group (n=20) and non-massive blood transfusion group (n=139). Clinical data of lung transplant recipients were statistically compared between two groups. The risk factors of perioperative massive blood transfusion were analyzed. Clinical prognosis of the recipients was observed in two groups. Results There were significant differences between the two groups in preoperative data including anticoagulant therapy, hemoglobin content, the number of recipents with idiopathic pulmonary fibrosis or idiopathic pulmonary hypertension, and intraoperative data including the number of recipents presenting with intraoperative intrathoracic adhesion, operation time and the amount of various component transfusion(all P < 0.05). Preoperative anticoagulant therapy, incidence of intraoperative intrathoracic adhesion, use of extracorporeal membrane oxygenation (ECMO) and long operation time were the risk factors of massive blood transfusion during perioperative period of lung transplantation(all P < 0.05). In the massive blood transfusion group, the incidence rate of grade Ⅲ primary graft dysfunction (PGD) and the fatality within postoperative 30 d were higher compared with those in the non-massive blood transfusion group(both P < 0.01). Low body mass index (BMI) and massive blood transfusion were the risk factors for death within postoperative 30 d(P=0.048、P < 0.001). The 1-year survival rate in the massive blood transfusion group was lower than that in the non-massive blood transfusion group(P < 0.001). Conclusions Preoperative anticoagulant therapy, incidence of intraoperative intrathoracic adhesion, use of ECMO and long operation time are the risk factors for massive blood transfusion during perioperative period of lung transplantation. Massive blood transfusion negatively affects the clinical prognosis of the recipients undergoing lung transplantation.

ABSTRACT

OBJECTIVE@#To analyze the clinicopathological characteristics and risk factors of 4L lymph node metastasis in left non-small cell lung cancer.@*METHODS@#We retrospectively analyzed the data of 134 patients undergoing surgical resection of left non-small cell lung cancer and 4L lymph node dissection, including 60 patients with squamous cell carcinoma (SCC) and 74 with lung adenocarcinoma (ADC). The clinicopathological characteristics of the patients were analyzed, and logistic regression analysis was used to identify the predictors of station 4L metastasis.@*RESULTS@#Of these patients, 16.4% (22/134) presented with station 4L metastasis. The patients with SCC and ADC showed significant differences in age, gender, smoking history, neoadjuvant chemotherapy, tumor size, tumor location and type, visceral pleural invasion, Ki-67 index, 4L metastasis and pathological TNM stage (stage Ⅱ). The rate of station 4L metastasis was significantly lower in SCC group than in ADC group. Univariate analysis revealed that pathological types (SCC or ADC), visceral pleural invasion, lymphovascular invasion, tumor markerabnormality, and station 5 to 10 metastasis were all high-risk factors for station 4L metastasis. Multivariate analysis suggested that the pathological type (OR=0.120, @*CONCLUSIONS@#In patients with left non-small cell lung cancer, station 4L metastasis is not rare and is more likely to occur in patients with lung adenocarcinoma. Dissection of the 4L lymph nodes should be performed in cases with low risk of damages of the adjacent tissues and high risk of station 4L metastasis.

ABSTRACT

BACKGROUND@#Mathematical predictive model is an effective method for preliminarily identifying the malignant pulmonary nodules. As the epidemiological trend of lung cancer changes, the detection rate of ground-glass-opacity (GGO) like early stage lung cancer is increasing rapidly, timely and proper clinical management can effectively improve the patients' prognosis. Our study aims to establish a novel predictive model of malignancy for non-solid pulmonary nodules, which would provide an objective evidence for invasive procedure and avoid unnecessary operation and the consequences.@*METHODS@#We retrospectively analyzed the basic demographics, serum tumor markers and imaging features of 362 cases of non-solid pulmonary nodule from January 2013 to April 2018. All nodules received biopsy or surgical resection, and got pathological diagnosis. Cases were randomly divided into two groups. The modeling group was used for univariate analysis and logistic regression to determine independent risk factors and establish the predictive model. Data of the validation group was used to validate the predictive value and make a comparison with other models.@*RESULTS@#Of the 362 cases with non-solid pulmonary nodule, 313 (86.5%) cases were diagnosed as AAH/AIS, MIA or invasive adenocarcinoma, 49 cases were diagnosed as benign lesions. Age, serum tumor markers CEA and Cyfra21-1, consolidation tumor ratio value, lobulation and calcification were identified as independent risk factors. The AUC value of the ROC curve was 0.894, the predictive sensitivity and specificity were 87.6%, 69.7%, the positive and negative predictive value were 94.8%, 46.9%. The validated predictive value is significantly better than that of the VA, Brock and GMUFH models.@*CONCLUSIONS@#Proved with high predictive sensitivity and positive predictive value, this novel model could help enable preliminarily screening of "high-risk" non-solid pulmonary nodules before biopsy or surgical excision, and minimize unnecessary invasive procedure. This model achieved preferable predictive value, might have great potential for clinical application.

ABSTRACT

BACKGROUND@#Non-small cell lung cancer with left atrial tumor thrombus accounts for a small proportion of local advanced lung cancer. Whether surgery could bring benefits, as well as surgical options are still controversial, and have always been hot spots in surgical research. We report a single center experience of surgical treatment to non-small cell lung cancer with left atrial tumor thrombus, aim to figure out more reasonable treatment strategy.@*METHODS@#From August 2006 to July 2017, a total of 11 cases of non-small cell lung cancer with left atrial tumor thrombus underwent surgery in Thoracic Surgery Department of China-Japan Friendship Hospital. Clinical data, treatment options, pathological types and prognosis of these patients were collected to perform a retrospective study.@*RESULTS@#Of the 11 patients (mean age of 57.9), 7 were men and 4 were women. Six of them received neoadjuvant radiotherapy and/or chemotherapy. All patients underwent smooth operation, including 3 cases with cardiopulmonary bypass, 1 case of posterolateral approach under extracorporeal membrane oxygenation, 6 cases of conventional posterolateral approach and 1 case of video-assisted minithoracotomy. Nine patients were evaluated as R0 resection while 2 cases were evaluated as R1 resection. The Surgeries cost an average of 292 min (210 min-380 min), with an average of 436 mL (100 mL-1,600 mL) blood loss. One patient (9.1%) died within 90 days after surgery, and another 4 cases (36.4%) suffered postoperative complications such as arrhythmia, cerebral infarction or hypoxemia. Six cases of squamous cell carcinoma, 4 cases of adenocarcinoma and 1 case of sarcomatoid carcinoma were identified by pathology. Seven cases were staged as pT4N0M0 while 4 cases were staged as pT4N1M0. Nine patients underwent adjuvant chemotherapy, and two patients underwent radiotherapy during follow-up. The overall follow-up time was 2 to 53 months, the 3-year disease-free survival rate was 30.7%, the median disease-free survival time was 31 months, the 3-year overall survival rate was 49.1% and the median overall survival time was 33 months.@*CONCLUSIONS@#For selected patients of non-small cell lung cancer complicated with left atrial tumor thrombus, choose a reasonable surgical approach to resect both the tumor and the thrombus, strengthen the perioperative management and apply neoadjuvant/adjuvant radiotherapy and/or chemotherapy, might obtain satisfying prognosis.

ABSTRACT

BACKGROUND@#Lung cancer and chronic obstructive pulmonary disease (COPD) are both common diseases in respiratory system and the leading causes of deaths worldwide. The purpose of this study was to determine whether the severity of COPD affects long-term survival in non-small cell lung cancer (NSCLC) patients after surgical resection.@*METHODS@#A retrospective research was performed on 421 consecutive patients who had undergone lobectomy for NSCLC. Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed.@*RESULTS@#A total of 172 patients were diagnosed with COPD, 124 as mild (GOLD-1), 46 as moderate(GOLD-2), and 2 as severe (GOLD-3). The frequencies of recurrence were significantly higher in higher COPD grades group (P<0.001). Recurrence-free survival at five years were 78.1%, 70.4%, and 46.4% in Non-COPD, GOLD-1 COPD, and GOLD-2/3 COPD groups, respectively (P<0.001). In univariate analysis, age, gender, smoking history, COPD severity, tumor size, histology and pathological stage were associated with recurrence-free survival. Multivariate analyses showed that older age, male, GOLD-2/3 COPD, and advanced stage were independent risk factors associated with recurrence-free survival.@*CONCLUSIONS@#NSCLC patients with COPD are at higher risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor. The severity of COPD based on pulmonary function test can be a useful indicator to identify patients at high risk for recurrence. Therefore, it can contribute to adequate selection of the appropriate individualized treatment.

ABSTRACT

Objective To investigate the regularity of intrapulnonary lobar and segmental lymph nodes metastasis in patients with cT1N0M0 stage lung adenocarcinoma.To provide a basis for more accurate determination of N stage and indication for pulmonary segmental resection.Methods A prospective study was performed from March 2014 to December 2015.103 cases of cT1 N0M0 stage lung adenocarcinoma received lobectomy and mediastinal lymph node dissection in the thoracic surgery department of China-Japan Friendship Hospital.Intrapulmonary lobar and segmental lymph nodes were dissected and sorted carefully then sent to the pathological department with the corresponding lung specimen and other lymph nodes.Statistical analysis was carried out considering size of the lesion,imaging features,serum CEA levels,pathological subtypes and so on.Results In total 103 cases,pN0 was confirmed in 82 cases,pN1 in 15 cases,pN1 + N2 in 5 cases,and skipping-pN2 in 1 case.14 cases(93.3%) in pN1 group were detected with station 12-14 lymph node metastasis,while only 5 cases (33.3%) were detected with station 12-14 LSNs metastasis.4 cases(66.7%) in pN2 group were detected with station 12-14 lymph node metastasis,while only 1 case(16.7%) with station 13 and station 7 lymph node metastasis.If LSNs were not detected,the false negative rate of N staging could be as high as 6.1% (5/82),The rate of missed diagnosis of lymph node metastasis might be 30% (6/20) to N1 stations alone.41.2% (7/17)cases with metastasis to the adjacent LSNs had been proved with metastasis to the isolated LSNs.The metastasis rate of the isolated LSNs was significantly lower(P =0.049) in pure GGNs compared with those part-solid/solid nodules.Invasive adenocarcinoma had higher metastasis rate of isolated LSNs,compared with preinvasive lesions or minimally invasive adenocarcinomas,with no statistical difference between groups (P =0.055).No significant difference in isolated LSNs metastasis rate was found between groups with different serum CEA levels(P =0.251) or tumor size(P =0.197).Conclusion Dissection of intrapulmonary lobar and segmental lymph nodes might facilitate a more accurate N stage,reduce the false negative rate of lymph node metastasis,and provide basis for more accurate assessment of prognosis and postoperative adjuvant treatment.The sampling area of lymph nodes during segmental resection should include the adjacent LSNs of the target segment.The isolated LSNs metastasis rate of cT1N0M0 stage lung adenocarcinoma with pureGGN as imaging feature is relative low,which might be suitable for segmentectomy when meeting other criteria.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the prognostic impact of preoperative (18)F-fluorodeoxyglucose (FDG) PET-CT on postoperative recurrence in patients with completely resected stage I non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>The clinic data of 182 patients with stage I NSCLC who underwent (18)F-FDG PET-CT scan before surgical resection between June 2005 and June 2012 were reviewed retrospectively. There were 121 male and 61 female patients, with an average age of 68 years (range from 34 to 85 years). The pathological stage was I A in 98 patients, I B in 84 patients; the histology were adenocarcinoma in 137 patients, squamous cell carcinoma in 35 patients, and others in 10 patients. Clinicopathological factors including gender, age, smoking history, SUV(max), surgical procedure, pathological features and adjuvant chemotherapy were evaluated to identify the independent factors predicting postoperative recurrences by univariate and multivariate analysis. The survivals were calculated by the Kaplan-Meier method and differences in variables were analyzed by the Log-rank test.</p><p><b>RESULTS</b>The postoperative recurrence rate was 15.9%. The univariate analysis identified that the SUV(max) (t=3.278, P<0.001), p-stage (χ² =5.204, P=0.026), blood vessel invasion (χ² =5.333, P=0.027) and visceral pleural invasion (χ² =7.697, P=0.009) are factors for predicting postoperative recurrence. Only SUV(max) was found to be a significant independent factor according to multivariate analysis (HR=1.068, 95%CI: 1.015 to 1.123, P=0.001). The study population was stratified into three groups by SUV(max), patients with SUV(max) > 5.0 had significantly higher risk of recurrence (23.9%) than those with 2.5 < SUV(max) ≤ 5.0 (15.0%) and SUV(max) ≤ 2.5 (7.3%) (P=0.043); patients with SUV(max) ≤ 2.5 had significantly better 5-year recurrence-free survival rate (90.9%) than those with 2.5 < SUV(max) ≤ 5.0 (82.7%) and SUV(max) ≤ 2.5 (71.0%) (P=0.030). There was a trend toward higher probability of blood vessel invasion (χ² =20.267, P < 0.001), visceral pleural invasion (χ² =6.185, P=0.045) and pathological stage I B (χ² =13.589, P=0.001) with increased SUV(max).</p><p><b>CONCLUSIONS</b>Preoperative SUV(max) of primary tumor is a predictor of postoperative relapse for stage I NSCLC after surgical resection. Therefore, it can contribute to the risk stratification for patients with the same pathological stage and selecting the optimal postoperative follow-up and therapeutic strategy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To probe the clinical application and value of dual source CT quantification volume imaging to forecast lung cancer patients' postoperative pulmonary function changing.</p><p><b>METHODS</b>Between June 2012 and June 2013, there were 233 patients (121 male patients and 112 female patients, with a mean age of (53 ± 16) years) who accepted the thoracoscope lobectomy or unilateral holo-lungs pneumonectomy accepted pulmonary function test before and after 3 months of the surgery. CT scan was conducted at both inspiration phase and expiration phase before the surgery and the lung volume of the single lobe, the pixel exponential distribution histogram, and the average lung density were measured after CT scan. The discrepancy and correlation between the preoperative lung volume accepted by CT and preoperative, postoperative pulmonary function index were compared.</p><p><b>RESULTS</b>The CT volume scan showed that average lung density of the superior part at decubitus position is -(870 ± 22) HU, the inferior part was -(767 ± 16) HU (t = 3.13, P < 0.01). The volume ratio of the right upper lobe, right middle lobe, right lower lobe, left upper lobe, left lower lobe were 20.5%, 10.3%, 23.1%, 24.6%, 21.5%, whole-right lung was 53.9% and whole-left was 46.1%. There were high correlation between CT volume index and preoperative routine pulmonary function index such as total lung capacity, forced vital capacity (FVC), forced expiratory volume in the first second (FEV(1)), residual volume, and FEV(1)/FVC. The highest correlation coefficient were 0.92, 0.76, 0.70, 0.85, 0.56 (t = 3.14, 3.05, 2.86, 3.09, 2.68; all P < 0.01). The highest correlation coefficient for the postoperative pulmonary function index were 0.87, 0.68, 0.75, 0.81, -0.64 (t = 3.10, 2.85, 3.05, 3.02, 2.79; all P < 0.01).</p><p><b>CONCLUSIONS</b>It is feasible to use dual source CT quantification volume imaging to predict lung cancer patients' postoperative pulmonary function alteration, which can provide precise predictive value of these patients. CT quantification volume imaging technology has important clinical application value.</p>

ABSTRACT

BACKGROUND:Orthotopic lung transplantation model in a rat is the key to investigate the chronic rejection after lung transplantation. However, the precise surgical technique and difficult operation limit the application of the model. OBJECTIVE:To improve the process of anesthesia and lung transplantation, and to establish a rapid, safe and reversible rat lung transplantation model. METHODS:A total of 42 rats were used to establish the model, including 21 donor models and 21 receptor models. The donor lung was excised by median sternotomy with dissection of the left lung and implantation of cuffs (intravenous catheters cut into 1.5 mm sections). The left lung was implanted in the recipient by lateral thoracotomy using the cuffs for anastomoses. The duration of surgery and success rate of transplantation were recorded and calculated. RESULTS AND CONCLUSION:The survival rate of rats after lung transplantation was 100%. The time of left donor lung extraction was (35.3±5.1) minutes in average. The time of placing cuff in donor lung was (12.5±4.6) minutes in average. The surgical procedure time of recipient was (50.2±3.3) minutes. The time of arteriovenous and bronchus casing anastomosis was (27.7±6.2) minutes. After pulmonary artery and vein blood flow was disparked, the whole lung turned red rapidly, blood perfusion was sufficient, venous returned unimpeded;after mechanical ventilation resumed, al graft lungs expanded wel . This improved anesthesia and lung transplantation technique in rats can provide a valid, reliable and reproducible animal model for studying immune responses and rejection in lung transplantation.

ABSTRACT

BACKGROUND:Through a ful investigation of biodegradable scaffolds, we propose a new self-expanding degradable poly-L-lactide coated endotracheal stent based on the design, production, experimental and clinical applications of nickel titanium memory alloy stent. OBJECTIVE:To design a kind of biodegradable endotracheal stent with poly-L-lactide and hydroxyapatite, and to test its mechanical properties, biocompatibility and biodegradation capacity. METHODS:With the technology of computer aided design, the stents were prepared with poly-L-lactide (Mr RESULTS AND CONCLUSION:The average radial supporting force of the tracheal stent was 7.8 kPa, the percentage of stent surface coverage was less than 20%, the stent expansion rate was≥4%, and the stent longitudinal shortening rate was≤9%, which reached the mechanical requirements for degradable endotracheal stents. After 4-16 weeks, there was no significant inflammatory response. The decline in molecular weight changes and weight loss ratio was higher for in vivo degradation than in vitro degradation at different time (P<0.05). These findings indicate that poly-L-lactide/hydroxyapatite composite stents have good mechanical properties, biocompatibility and biodegradability. 150 000) and hydroxyapatite materials, 20 mm to 26 mm in diameter. The mechanical properties were tested using a universal testing machine. These poly-L-lactide/hydroxyapatite stents were implanted into dog models of tracheal stenosis at an appropriate size. The histopathological changes of the tracheas were observed, and biodegradation property was studied via molecular weight changes and weight loss ratio after 4, 8, 12, 16 weeks.

ABSTRACT

The present case report was designed to summarize the clinical experience of operative technique. lung preservation, lung perfusion, and perioperative management. Of 7 cases who underwent allogenic single lung transplantation (LT), 3 were idiopathic pulmonary fibrosis, 2 were chronic obstructive pulmonary disease, 1 was silicosis, emphysema, and bulla, and I was tuberculosis in both sides and presented with destroyed lung in one side. All donors were already brain death. Donor lungs were well preserved utilizing Euro-Colins liquid or low-potassium dextran solution. Donors and recipients were matched in blood type. Of 7 cases selected,5 received single right lung transplantation, and 2 received single left LT. End-to-end anastomosis was performed for pulmonary branches and pulmonary arteries. while atrium-to-atrium anastomosis was performed for pulmonary vein. Antibiotics and immunosuppressants were routinely used prior to and subsequent to LT. Following LT, heart and lung function, usage of antibiotics, and adjustment of immunosuppressant were monitored. Stomal complications regarding bronchus and pulmonary artery and vein did not appear in any patient. Five cases survived for about 2 months, one for approximately 1 year, and one for nearly 2 years. Four cases died of multi-organ failure caused by pulmonary infection, and one of severe pulmonary hemorrhage caused by aspergillus sydowi infection. Rejection occurred in 6 cases. One case sufiered from rejection three times. Selection of indication, selection and preservafton of donor lung, LT operation and pre-and post-operative management of LT have acquired satisfactory achievements. High mortality occurred in patients with preoperative poor cardiac and pulmonary functions and postoperative severe infections accompany with application of immunosuppressant.

ABSTRACT

<p><b>BACKGROUND</b>According to the international standard in TNM staging of pulmonary carcinoma, pulmonary carcinoma complicated with diffuse pleural metastasis and malignant pleural effusion belongs to IIIB stage. In the past, non-operative therapy was employed, but both the therapeutic efficacy and the quality of life of patients were poor. The purpose of this study is to find out a complex treatment for this disease.</p><p><b>METHODS</b>Total pleuro-pneumonectomy was performed in 55 cases of patients with pulmonary carcinoma complicated with diffuse pleural metastasis and malignant pleural effusion from December 1978 to February 2003. The patients were followed up postoperatively, and the quality of life and survival period of them were observed.</p><p><b>RESULTS</b>In all the cases, only 2 patients died of operation. Satisfactory recovery and remarkable relief of symptoms such as short breath, dyspnea and chest pain were found in all the other patients. After a follow-up period of 1-25 years, local recurrence was found in 6 cases (11.3%), and distant metastasis in 42 cases (79.2%). A total of 48 patients died of tumor, with survival period ranging from 5-40 months (average survival period: 15 months; median survival period: 14 months), and 5 patients were still alive in good health.</p><p><b>CONCLUSIONS</b>(1) Patients appropriated for operation should be carefully selected in case that postoperative complications influence their smooth recovery; (2) Tumor tissues should be removed as clear as possible; (3) During the operation, close attention should be paid to the protection of incisions; (4) Removal of the tumor tissues can reduce the tumor load, effectively clean the immunosuppressive factors in malignant pleural effusion, and break the immunity block status, which provides basis for the following comprehensive therapy; (5) The quality of life of the patients can be improved and the median survival period can be prolonged by the operation; (6) The long-term survival rate of patients is still unsatisfactory.</p>

ABSTRACT

Thoracoscopic esophagectomy is an alternative to open thoracotomy in treatment of esophageal carcinoma, but its role in esophageal surgery is still controversial. Between May 2000 and May 2002, 9 patients affected by esophageal carcinoma underwent esophagectomy with thoracoscopic dissection of the esophagus. Seven patients were male, 2 were female,and the mean age was 51 (range, 42~56) years.One patient had the carcinoma at cervical segment, 2 at upper third thoracic segment, 5 at middle third, and 1 at lower third.All tumors were squamous cell type and were below stage II.Thoracoscopy and cervical esophagogastrostomy were successfully performed in 8 patients except in one case, in whom conversion to thoracotomy was necessary because of extensive tumor invasion.Thoracoscopic dissection took an average of 70 (range,40~120) minutes and the mean operative time was 252(range,230~270) minutes. the mean operative blood loss was 250ml (range,150~400ml) and the mean number of thoracic lymph nodes harvested was 7(range,5~12).One patient experienced a cervical infection,which healed with conservative treatment.One patient had a temporary left recurrent nerve palsy that disappeared during the following 6 months.These initial data indicate that thoracoscopic esophagectomy is safe and feasible. The short term result of thoracoscopy is comparable with that of open thoracotomy, and the long term result and its role in esophageal surgery deserve further investigation.

ABSTRACT

Objective To investigate the expression of LRP16 gene in lung cancer, and explore its clinicopathological significance. Methods Fresh resected tissues from 54 patients with primary lung cancer were collected and the clinicopathological data were gathered. The expression of LRP16 protein in cancer tissues and the matched normal tissues were determined by Western blotting, and the relationship between LRP16 expression and clinicopathological data was analyzed. It was defined as overexpression when the LRP16 expression of cancer tissues was twice or more higher than that of matched normal tissues. Results The LRP16 was overexpressed in 15 out of 54 patients with lung cancer (27.8%). Among the 23 patients with adencarcinoma, the overexpression of LRP16 was found in 11 cases (47.8%), while in the patients with squamous carcinoma, the overexpression of LRP16 was only found in 4 out of 27 cases (14.8%), and there was a significant difference between the two groups (Pearson test, P=0.0258). Besides, very low expression or non-expression of LRP16 was found in 2 large cell lung cancer and 2 small cell lung cancer. The overexpression rate of LRP16 was 20.0% (2/10) in tumor with diameter less than 3cm and 29.5% (13/44) in tumor with diameter ≥3cm, and there was no significant difference between the two groups (Pearson test, P=0.7224). Conclusions There were significant differences of LRP16 overexpression in cases of adencarcinoma or squamous carcinoma with or without lymphatic metastasis.

ABSTRACT

Objective To review and sum up the clinicopathologic features and surgical therapeutic efficacy of intrathoracic Castleman′s disease (CD). Methods 14 patients with intrathoracic Castleman′s disease, 7 in each sex, aged from 19 to 52, admitted during 1982 to 2005, all underwent surgical treatment, among which 11 with localized type and 3 with multicentric type, were retrospective analyzed on their clinicopathologic features, radiological signs, treatment and prognosis. Results Clinically, 3 patients of localized type were with systematic symptoms; all the patients of multicentric type were with various severity systematic symptoms. Pathological type: 9 cases with hyaline vascular type (HV), 2 cases with Plasma type (PC), and 3 cases with Mixed type (Mix). A different pattern of pathologic alterations existed between HV、PC and Mix types of CD. Radiological features: in localized type of CD, the lesion presented as a solitary soft-tissue mass with a mean diameter of 5.05cm, the mean CT value was 37.39HU. In 3 cases with multicentric type of CD, diffuse mediastinal lymphadenopathy and pleural effusion were observed. All patients survived after surgical resection, long-term survival was achieved in 11 cases with localized type and 2 cases with multicentric type, no recurrence occurred in the 13 patients. Recurrence occurred twice in a patient with multicentric Mix type in the fourth and the ninth year after surgery, respectively, thus the operative treatment followed. Conclusions The diagnosis of CD is based mainly on its histopathological features. The patients with intrathoracic localized type of CD and part of the patients with multicentric type CD could be cured, while part of the patients with multicentric type CD got a poor therapeutic efficacy and unfavorable prognosis even underwent with radiotherapy and integrated treatment.

ABSTRACT

Objective To summarize the characteristics on diagnosis and therapy of adult diaphragmatic eventration. Method The clinical data of 26 patients with adult diaphragmatic eventration, hospitalized in General Hospital of PLA from 1988 to 2009, were retrospectively analyzed. The 26 patients, 14 males and 12 females, were aged from 26 to 66 (mean 44.0?5.7), with disease course of 8 months to 17 years. Among them 25 suffered from left and 1 from right diaphragmatic eventration; 24 with total and 2 with localized diaphragmatic eventration; of them 2 without symptoms were detected in physical examination, and among the 24 remainders 18 were with the symptoms of thoracic discomfort after eating, 8 with dyspnea after activities, 14 with hiccup, vomiting and abdominal discomfort. Most of the patients had more than one symptom. All patients received operations via the chest cavity under general anesthesia, 24 cases were performed by double mattress suture with diaphragm discission, while 2 cases by fold suture without diaphragm discission. Results Symptoms relief was reported in 24 patients at the early stage after operation. Eighteen patients were followed up for one year, and 15 of them received chest radiograph, among whom the normal diaphragm localization were in 13 cases and relatively higher diaphragm localization in 2 cases, while the other 3 patients received no re-examination of chest radiograph. Among the 18 cases receiving one year of follow-up, 10 cases got complete disappearance of symptoms, 6 cases got symptoms relieved or partially disappeared, and 2 patients got symptom relapsed. Conclusion Surgical outcome, especially the double mattress suture is satisfactory for adult diaphragmatic eventration.
