Current morbimortality and one-year survival after pneumonectomy for infectious diseases.

OBJECTIVE: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease. METHODS: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate. RESULTS: 56 procedures were performed. The average age was 44 years, with female predominance (55%). 29 cases were operated on the left side (51%) and the most frequent etiology was post-tuberculosis (51.8%). The overall incidence of complications was 28.6% and the most common was empyema (19.2%). Among empyema cases, 36.3% required pleurostomy, 27.3% required pleuroscopy and 36.3% underwent thoracoplasty for treatment. Bronchial stump fistula was observed in 10.7% of cases. From all cases, 16.1% were completion pneumonectomies and 62.5% of these had some complication, a significantly higher incidence than patients without previous surgery (p = 0.0187). 30-day in-hospital mortality was (7.1%) with 52 cases (92.9%) and 1-year survival. The causes of death were massive postoperative bleeding (1 case) and sepsis (3 cases). CONCLUSIONS: Pneumonectomy for benign disease is a high-risk procedure performed for a variety of indications. While morbidity is often significant, once the perioperative risk has passed, the one-year survival rate can be very satisfying in selected patients with benign disease.

The impact of lung cancer resection surgery on fibrinogen and C-reactive protein and their relationship with patients outcomes: A prospective follow up study.

BACKGROUND: Major thoracic surgery is characterized by release of inflammatory markers.The objective of this study was to assess the preoperative and postoperative systemic inflammatory markers of patients undergoing lung cancer resection. METHODS: This is a prospective follow up study conducted with 48 patients submitted to lung cancer resection.All patients were assessed before and 1 month after surgery through measurement of fibrinogen and C-reative protein(CRP), pulmonary function tests, 6- minute Walk Test (6 MWT), maximal inspiratory pressure (PImax) and maximal expiratory pressure (PEmax), anxiety and depression scale and karnofsky performance status scale. RESULTS: Both fibrinogen and CRP were higher 1 month after surgery, although only the change in CRP was statistically significant (p= 0.03). The following functional parameters: 6 MWT, PImax, PEmax, FEV1(%) and FVC(%) decreased after surgery with p ≤ 0.001 for all the parameters. Anxiety and depression improved and Karnofsky decrease after surgery (p= 0.03, p= 0.01 and p= 0.02; respectively). Change in CRP score following lung resection correlated significantly with changes in fibrinogen (r= 0.40; p= 0.003), change in Karnofsky scale (r= -0.50; p< 0.001) and a borderline significant trend with the 6 MWT (r= -0.28; p= 0.05). With the exception of video-assisted thoracoscopic surgery (VATS), who had a significantly lower fibrinogen level 1 month after surgery compared with thoracotomy (p= 0.01), no significant differences in fibrinogen or CRP were noted in other subgroups of patients considered at increased risk for higher levels of inflammation compared with lower risk counterparts. CONCLUSION: Lung cancer resection surgery was associated with increased level of CRP, 1 month after surgery, and correlated directly with change in fibrinogen and inversely with measurement of performance status. VATS provided lower level of fibrinogen after surgery.

Idiopathic tracheal stenosis: successful outcome with antigastroesophageal reflux disease therapy.

There is controversial evidence that gastroesophageal reflux disease (GERD) is an etiologic factor for idiopathic laryngotracheal stenosis. We present the case of a 44-year-old woman with symptomatic tracheal stenosis managed as idiopathic stenosis. She underwent six endoscopic dilations during 1 year, and before surgery she underwent 24-hour esophageal pH monitoring that documented GERD. Anti-GERD treatment was started, which was confirmed as effective with 24-hour esophageal pH monitoring 3 months later. At 2-year follow-up the patient remained free of symptoms and no additional airway procedure was necessary. A close relationship between anti-GERD therapy and clinical outcome was noted.
