Surgical treatment for 30 patients with tracheal and main bronchial tumors

Objective To study the surgical treatment of tracheal and main bronchial tumors. Methods We retrospectively analyzed the clinical data of 30 patients with tracheal and main bronchial tumors treated in Shengjing Hospital of China Medical University from January 2000 to December 2015. There were 12 males and 18 females with the age ranging from 22 to 80 years. Results Ten patients were treated with enucleation, 12 patients tracheal tumor resection and end-to-end anastomosis, 1 patient window resection, 1 patient wedge resection, 5 patients tumor resection and tracheal reconstruction by using pulmonary tissue flap with alloy stent and 1 patient left pneumonectomy. One patient died of sudden massive hemoptysis 26 d after operation. Intraoperative complications were found in 2 patients. Others had a good recovery after operation. Patients were followed up for 11 months to 14 years. Eight patients were followed up less than 5 years postoperatively, one patient died of sudden massive hemoptysis 14 months after operation, while others survived; 21 patients were followed up more than 5 years and 5 patients were lost to follow-up. Conclusion Surgical resection is recommended for tracheal and main bronchial tumors. Patients with small benign tumor may choose local tracheal resection; tracheal segmental resection and end-to-end anastomosis is the most common surgical treatment. Patients with more than half of the whole length of tracheal defects or in the risk of anastomotic ischemic necrosis may be suggested to receive tracheal reconstruction.

Cardiovascular events after acute exacerbation of bronchiectasis

Objective To investigate the cardiovascular events (CVE) and survival status of patients with bronchiectasis (BE) during follow-up after acute exacerbation. Methods Prospective cohort study was used. Clinical data of 134 BE patients with acute exacerbation who were hospitalized from July 2016 to September 2020 were collected. The patients were followed up after discharge by phone or respiratory clinic every 3 months until November 2022. CVE or death was the endpoint event. Result During the follow-up period, 41 patients developed CVE, while 93 patients did not. Fifty-one patients died during the follow-up period, with a mortality rate of 38.06%. Among them, 41 cases of CVE resulted in 21 deaths, with a mortality rate of 51.22%; 30 cases died in 93 non-CVE patients, with a mortality rate of 32.26%. Logistic regression results showed significant influencing factors for CVE in BE patients were age, hypertension, chronic obstructive pulmonary disease (COPD), and moderate to severe illness. The significant influencing factors for the death of BE patients were age, COPD, moderate and severe illness, and CVE events. The significant influencing factors for the death of CVE patients were age and receiving CVE treatment. The area under ROC curve (AUC) and 95%CI was 0.858 (0.729 - 0.970) for the warning model for CVE in BE patients. The AUC (95%CI) was 0.867 (0.800 - 0.927) for the warning model for death in BE patients. The AUC (95%CI) was 0.811 (0.640 - 0.976) for the warning model for death of CVE patients. Conclusions Population factors and comorbidities are risk factors for CVE in BE patients after acute exacerbation. The appearance of CVE worsens the long-term prognosis of BE patients. The corresponding warning models have high warning effectiveness with AUC>0.8.

Concurrence of Obstructive Sleep Apnea Hypopnea Syndrome with Asthma

ObjectiveTo evaluate the prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) in patients with asthma, and explore the association of OSAHS with asthma. MethodsPatients who were diagnosed as asthma between March 2014 and February 2015 were recruited in the study. They were categorized into an OSAHS group and a non-OSAHS group according to the Berlin questionnaire. The data of clinical characteristics and pulmonary function test were collected. Logistic regression analysis was performed to evaluate the factors associated with the incidence of OSAHS in asthma. ResultsA total of 64 patients with asthma were enrolled and 36 patients were complicated with OSAHS. The body mass index (BMI), allergic rhinitis history, inspiratory capacity, maximal mid-expiratory flow and provoking dose which make FEV1 reduce 20% were significantly different between two groups (all P < 0.05). Multivariate logistic regression analysis revealed that the increased BMI was an independent risk factor of OSAHS in patients with asthma. ConclusionThe occurrence of OSAHS with asthma is very high, and BMI may be an important associated risk factor.

COMPARISON OF SEVERAL RIB RINGS WITH INTERCOSTAL MUSCLES FOR TRACHEAL REPLACEMENT IN DOGS

OBJECTIVE: To compare the effect of several types of rib rings with intercostal muscles for the replacement of trachea in thorax. METHODS: The surface layer of the third rib of dogs were ripped off and curved into triangular, quadrilateral and polygonal form. These three types of rib rings with intercostal muscles were used to replace a segment of trachea in thorax. RESULTS: The stability of triangular rib ring was very well, but stricture of ring were often happened because of its smaller internal diameter. These stability of quadrilateral rib ring was the worst. The polygonal rib ring presented the biggest diameter and good stability compared to the other two kinds of rings. If silicone tube was supplemented in the polygonal rib ring, the quality of artificial trachea was excellent. CONCLUSION: The rib rings with intercostal muscles are successfully used for replacing the defect of trachea in canine thorax. The polygonal rib rings have the best quality in the three types of rib ring for tracheal replacement.

Treatment for Patients with Primary Tracheal Tumors

Abstract: ObjectiveTo explore the surgical characteristics of primary tracheal tumors treatment and its prognosis. Methods [WTBZ]We retrospectively investigated the clinical records of 38 patients with primary tracheal tumors in both Xiangya Hospital of Central South University and Hunan Provincial Tumor Hospital from Febuary 1982 to August 2009. There were 24 males and 14 females aged from 7 to 65 years. There were 2 benign lesions, 13 adenoid cystic carcinomas, 11 squamous cell carcinomas, 5 mucoepidermoid carcinomas, 4 adenocarcinomas and 3 other cell types. One patient with adenocarcinoma underwent exploratory thoracotomy only; 33 patients underwent tracheal resection and airway reconstruction, and according to the tumor growth characteristics, the surgeon applied circumferential tracheal resection with endtoend anostomosis or wedge resection; One patient had papilloma resected under fiber bronchoscopy; and three patients with locally advanced lesions underwent radiotherapy without surgery. The overall survival rate was calculated by the KaplanMeier method. The logrank method was used for comparing survival rates among different groups, characterized by cell types or surgical procedures. Results [WTBZ]The patient with exploratory thoracotomy died 3 days after surgery from respiratory failure. The perioperative mortality was 2.94% (1/34), and all the remaining 33 patients recovered and were discharged from hospital. Minor complications happened to 12 patients (35.29%), including 6 patients with pulmonary infection, 4 with atelectasis, and 2 with hoarseness. The followup time ranged from 6 months to 15 years. The followup rate was 97.29% (36/37). The threeunresected patients died within 6 months after hospital discharge. The 1, 5, and 10year survival rate for resected patients was88% （95%CI 0.77 to 0.99), 47%(95%CI 0.29 to 0.66), and 41% (95%CI 0.21 to 0.61), respectively. The survival rate of adenoid cystic carcinoma or mucoepidermoid carcinoma was significantly higher than that of squamous cell carcinoma or other tissue types (χ2=17.581, P=0.001). There was no statistical difference (χ2=0.021, P=0.886) in 5 year survival rate between wedge resection group at 63%(95%CI 0.34 to 0.91) and the segmental resection group at 77%(95%CI 0.44 to 0.99). Conclusions [WTBZ]Surgical treatment is safe and beneficial for primary tracheal tumors, and the pathological type is a significant prognostic factor after complete resection.
