[Iatrogenic esophago-tracheal fistula treated with endoscopically administered fibrin glue].

Successful closure of a iatrogenic tracheoesophageal fistula by means of bronchoscopic application of fibrin glue in a 77-year old patient is reported. The fistula was completely obliterated after a single application of the glue, with resolution of the clinical and radiological signs. The procedure may be suggested as an alternative to surgery or as first attempt before surgery in very selected patients with TEF.

Bronchoplastic and angioplastic techniques in the treatment of bronchogenic carcinoma.

From 1979 to 1991, 51 bronchoplasties, 18 angioplasties, and 4 combined broncho-angioplasties were performed for bronchogenic carcinoma. Sixteen patients underwent operation because of compromised pulmonary function; bronchoplasty, angioplasty, or the combined procedure was performed in the remaining 57 patients because of a suitable anatomic location of the neoplasm. Twenty-four patients had stage I disease, 32 stage II, and 17 stage IIIa. Three patients died postoperatively (3.65%). Major postoperative complications occurred in 20 patients (27.3%) (10 early, and 10 late). A completion pneumonectomy was required in 4 patients (5.4%), 2 for anastomotic stricture, 1 because of vascular thrombosis after angioplasty, and 1 for local recurrence after angioplasty. Three-year and 5-year survival rates for the entire group were 55.4% and 40.8%, respectively. One-year and 3-year survival rates after angioplasty were 78.6% and 31.4%. Of the 4 patients who underwent a combined bronchoangioplastic procedure, 1 died after 23 months and 3 are alive and well after 11, 15, and 20 months. Survival was more favorable in the combined N0-N1 group (62% and 43.1%) than in the N2 group (23.4%), but the difference was not significant (p < 0.2). Three-year survival after angioplasty was found to be lower than, although not significantly different from, the overall 3-year survival rate (31.4% versus 55.4%; p = not significant). No statistically significant differences were found among survival rates of patients with compromised and noncompromised pulmonary reserve. We conclude that bronchoplastic and angioplastic procedures are valid techniques as curative operations in carefully selected patients with bronchogenic carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Thymoma: results of 241 operated cases.

Clinical and histopathological aspects of 241 thymomas were reviewed. One hundred sixty of the patients with thymoma had myasthenia gravis and 15 had other autoimmune diseases; 55% of the thymomas were encapsulated and 45% invasive. Operation was radical resection in 87.5% of the patients, subtotal resection with residual tumor in 8.7%, and simple biopsy in 3.7%. A tumor relapse was observed in 24 patients (10%): 2 (1.5%) of 133 with encapsulated thymomas and 22 (20.4%) of 108 with invasive thymomas; among these patients, a relapse was found in 20.6% of the patients who received radiotherapy postoperatively and in 24.6% who did not. Adverse prognostic factors were clinical stage IVa (multiple pleural nodes), not feasible resection (for technical reasons), inoperable tumor relapse, and association with one of the following autoimmune diseases: pure red cell aplasia, hypogammaglobulinemia, and lupus erythematosus. Conversely, myasthenia gravis is now a curable disease; it contributes to early discovery of associated thymoma, thus allowing a better survival for patients with thymoma who have myasthenia gravis compared with patients with thymoma but without myasthenia gravis (p less than 0.05). Postoperative radiotherapy does not seem necessary after removal of encapsulated thymomas, but it is advisable in case of invasive thymomas, regardless of the extent of the resection.

Thymectomy in myasthenia gravis. Results of 662 cases operated upon in 15 years.

The results of thymectomy in the treatment of myasthenia gravis (MG) are reviewed in the light of a personal series of 662 MG patients, operated upon during the last 15 years. In 500 MG patients without thymoma, the following results have been achieved: remission 37.9%, improvement 49.4%, unchanged or worse 7.4%, dead 5.2%. There is no sex prevalence and the remission rate is higher in patients under 40 years of age (P less than 0.01), with mild disease (P less than 0.05), with a MG duration of less than 1 year (P less than 0.05) and with a follow-up length of between 5 and 10 years (P less than 0.01). No correlations are found between outcome and thymic histology. The results of 162 MG patients with thymoma are: remission rate 15.7%, improvement 60.3%, unchanged or worse 3.7% and dead 20.1%. The remission rate is higher with mild symptoms (P less than 0.05) and when the tumour is encapsulated (P less than 0.02). The postoperative mortality is 0.8% (none in the last 5 years) for non-thymomatous MG and 4.9% for thymomatous MG (2 of 8 patients died of pancytopaenia and 1 of pulmonary embolism).

The management of cystic fibrosis with carbocysteine lysine salt: single-blind comparative study with ambroxol hydrochloride.

The effectiveness of carbocysteine lysine salt monohydrate (SCMC-Lys) and ambroxol hydrochloride (ABX) in the management of respiratory impairment was compared in a single-blind, randomized study of 26 cystic fibrosis patients with similar baseline characteristics. Adults received either SCMC-Lys 900 mg or ABX 33 mg three times a day and children under 14 years of age either SCMC-Lys 270 mg three times a day or ABX 10 mg four times a day. All treatments were given orally for 80 days and at the end of this control period both groups showed significant improvement in chest sound score but improvement in cough score was observed only in those receiving SCMC-Lys. Expectorate viscosity and elasticity decreased significantly in both groups. In SCMC-Lys-treated patients paCO2 decreased and paO2 and Hb O2 saturation increased while only paO2 increased significantly in those treated with ABX. An increase in tidal volume, peak expiratory flow values and forced expiratory volume were evident in those receiving SCMC-Lys while significant increases in forced expiratory flow were recorded in those receiving ABX. SCMC-Lys patient's Shwachmann index improved significantly and conversely to the ABX patients. No adverse events were recorded in either treatment group. The study concluded that SCMC-Lys is at least as effective as ABX in improving respiratory function in patients with cystic fibrosis.

Clinical significance of tumor necrosis factor in patients with bronchogenic carcinoma and benign lung diseases: a comparative study.

Tumor Necrosis Factor (TNF) was determined in the serum of 72 lung carcinoma patients. Twenty-four healthy subjects younger than 50 years and 10 healthy subjects older than 70 years were considered as control group. TNF was also measured in 20 patients with stage I sarcoidosis and in 15 patients with pulmonary fibrosis. The marker was detected in 32% of cases in the neoplastic group, in 37.5% of disease confined to the chest and in 25% of advanced disease cases. A large proportion of TNF-positive samples was found in sarcoidosis (30%), and even larger in pulmonary fibrosis (66.6%). TNF was also present in healthy subjects older than 70 (40%). We conclude that TNF is not specific of malignancy, being demonstrable in other benign pulmonary diseases and even in the course of physiological aging.

[The surgical treatment of lung metastases. The prognostic factors and the indications for the surgical approach].

BACKGROUND: After the liver, the lungs represent the most frequent site of metastasis from primary tumours. Surgical treatment of lung secondary neoplasms leads to a significant improvement in survival. METHODS: Between 1960-1997, 178 patients with lung metastases underwent surgery at the Thoracic Surgery Department of Turin University in a total of 193 operations. A retrospective study was made in order to identify the prognostic factors which influenced final survival in this population. RESULTS: Overall survival was 47% after 2 years and 20% after five years. Prognosis was not influenced by the size of metastases, the type of surgery, adjuvant therapy and the number of operations on the same patient. On the other hand, useful prognostic factors were found to be the histological type of the primary tumour, the original site of the neoplasm, the number of metastases and, above all, the disease-free interval (DFI). CONCLUSIONS: Lung metastasectomy is an important therapeutic aid in selected patients, whereas the preoperative evaluation of the above prognostic factors enables a reasonably precise prognosis to be made in most patients.

[Neuroendocrine tumors of the lung].

BACKGROUND: To review the patients treated at our Institute over the past 22 years and to evaluate the behaviour of 14 atypical carcinoids on the basis of Capella's classification (1994), defining the most suitable surgical approach. METHODS: A total of 118 patients undergoing surgery for lung neuroendocrine tumours were reanalyzed on the basis of their anatomic and pathological characteristics, surgical treatment and survival. RESULTS: The 5-year survival rate was 96.5% for typical forms and 74.5% for atypical forms; the 10-year survival rate was 92.4% for typical forms and 49.8% for atypical forms (p < 0.001). Lymph node metastatic involvement was also an important contributing factor for survival (p < 0.05). A review of the series of 19 patients treated over the past 6 years, diagnosed with so-called atypical carcinoid based on Capella's anatomic and pathological classification, showed that 5 were well differentiated neuroendocrine tumours (WDNT), 8 well differentiated neuroendocrine carcinomas (WDNC) and 1 small-cell lung neuroendocrine carcinoma (SLCL). From a surgical point of view, 10 cases underwent demolitive surgery and 9 conservative surgery. The overall actuarial survival rate in this series was 78% at 5 years, 100% for WDNT and 75% for WDNC. The only case of SCLC died after a few months. CONCLUSIONS: The authors conclude that the 5 and 10-year probability of survival are closely linked to the histological type of the lung neuroendocrine tumour and the presence of lymph node metastasis. Capella's new anatomic and pathological classification helps to establish a more precise prognosis for so-called atypical carcinoids. Lastly, given the malignant potential of these tumours, preference should be given to radical exeresis.

The value of selective mediastinoscopy in predicting resectability of patients with bronchogenic carcinoma.

From 1980 to 1990, 1505 patients underwent thoracotomy as definitive treatment for non small cell lung cancer. Computed tomography (CT) of the chest has been used routinely since 1984 for assessment of mediastinal lymph node involvement. A total of 235 cervical mediastinoscopies and 71 anterior parasternal mediastinotomies were performed on the same patient population as preoperative staging when CT scan demonstrated mediastinal lymph nodes larger than 1 cm. Radical resections showed a constant increase in number from 70.1% in the period 1980-84 to 82.7% in the period 1985-90. Exploratory thoracotomies and thoracotomies with residual tumor showed a parallel reduction: 14.5% in 1980-84 to 7.4% in 1985-90 for the former, 15.4% in 1980-84 to 9.8% in 1985-90 for the latter. The percentage of N2 disease to the total number of thoracotomies decreased from 23.6% in 1980-81 to 11.2% in 1989-90. We conclude that a selective use of cervical mediastinoscopy and anterior parasternal mediastinotomy, based upon the results of CT scan, may have contributed to reduce the number of exploratory thoracotomies and thoracotomies with residual tumor.

Surgical applications of the greater omentum. A critical review of the literature.

The paper presents and discusses a review of the literature on the use of the greater omentum, focusing in particular on chest surgery. Following an introduction on the anatomy and surgical techniques of mobilisation based on the vascular anatomy of the organ, the author examines the applications of the greater omentum in general surgery. Among these, it is particularly interesting to note the possibility of covering anastomoses, above all extraperitoneal; the interposition of the omentum in the prevention of endoabdominal adhesive syndromes, the covering of pathological perforations of hollow viscera. Lastly, the Author illustrates the applications of the omentum in chest surgery, both preventive and due to endothoracic pathological processes. The Author mentions the covering of bronchial and tracheal anastomoses following resection or lung transplant; the covering of defects in the thoracic wall in patients with osteoradionecrosis or previous irradiation; its therapeutic use in broncho-pleural fistulae and in post-sternotomy mediastinitis.

Pleural abrasion in the treatment of recurrent or persistent spontaneous pneumothorax. Results of 94 consecutive cases.

In the ten-year period 1982 to 1991, 94 patients underwent pleural abrasion as definite treatment for spontaneous pneumothorax. Surgical indications included: 1) third recurrence of homolateral pneumothorax, 2) second recurrence of homolateral pneumothorax in the presence of alternating pneumothorax, and 3) persistent air leak with incomplete lung re-expansion in the presence of spontaneous pneumothorax treated with pleural drainage for more than 10 days. No deaths were observed in the present series. Post-operative complications were minimal and all reversible, including two cases of pleural effusion, one case of hemothorax, and one case of Horner's syndrome. Eighty cases were followed up from 7 to 91 months. No recurrences occurred during the follow-up period. Clinical, radiological and functional results appear satisfactory. Pleural abrasion seems to represent a valid surgical option in the treatment of recurrent or persistent spontaneous pneumothorax.
