[Results of repeated pulmonary resection in new homolateral neoplastic localization after conservative resection].

From 1978 through 1992, 93 patients with a previous lobectomy for bronchogenic cancer were referred for homolateral cancer recurrence. Forty-six patients were contraindicated for carcinologic reasons (30 stage IIIb and 16 stage IV). Forty-seven patients (50.5%) were resectable, but 17 did not undergo surgery for associated medical problems (n = 11) or refusal (n = 6). The remaining 30 patients form the population of the present study: 29 males and 1 female; mean age of 61 years (range 47-72). The previous cancer was stage I in 26 and stage II in 4. The mean interval between the 2 cancer diagnoses was 30 months (range 6-97). Three patients underwent an exploratory thoracotomy (10%): 2 had mediastinal involvement and 1 had pleural metastases. Twenty-two (73%) underwent a completion pneumonectomy, and 5 had miscellaneous conservative resections. There were 4 operative deaths (13%): one intraoperative bleeding, 1 postoperative bleeding, 1 pulmonary embolism, 1 pneumonia. Four patients had nonfatal surgical complications: 2 clottings (reexploration), 1 empyema (lavage) and 1 bronchopleural fistula (thoracoplasty). Resected patients were staged as follows: 13 stage I, 4 stage II, 10 stage III. Survival following resection including operative mortality at 3 an 5 years was estimated as 52.5% and 44% for the whole series (72% for stage I). We conclude that repeat surgery conveys an increased risk, but may achieve valuable long-term results.

Esophagopleural fistula: an early and long-term complication after pneumonectomy.

Over a 14-year period, we observed eight cases of esophagopleural fistula after pneumonectomy for cancer (n = 7) or infectious lung disease (n = 1). In 2 patients, the fistula was probably related to an intraoperative esophageal injury. Two others had mediastinal cancer recurrence, whereas a fistula developed in 4 without any malignancy. Patients presented with empyema, and a contrast swallow procedure disclosed an esophagopleural fistula. Two patients with recurrent cancer were managed conservatively with chest tube insertion and died within 3 months. A patient with chronic empyema had a delayed diagnosis of esophagopleural fistula 2 years after a presumed intraoperative injury; he was managed with thoracoplasty and feeding gastrostomy and died 12 months later. Five patients had an attempt at curative treatment. A single patient underwent thoracoplasty and bipolar exclusion of the esophagus and had secondary reconstruction with a coloplasty; he died with postoperative peritonitis. Four patients underwent thoracoplasty and muscle flap repair of the esophagus. There was 1 operative death from pulmonary embolism, whereas 3 patients recovered and are well with follow-up of 18 months, 2 years, and 5 years, respectively. We conclude that the prognosis of esophagopleural fistula is ominous when associated with cancer recurrence. A curative approach should combine direct repair of the esophagus with a muscle flap and eradication of the associated empyema with thoracoplasty. This aggressive treatment is addressed to debilitated patients and carries high rates of mortality and morbidity.

[Result of surgery of esophageal cancer. Analysis of a series of 349 cases based on resection methods].

Despite obvious improvements in operative and postoperative management after esophageal resection, surgical treatment of esophageal cancer is still disappointing in terms of long term results. The purpose of the present study was to verify these poor results statistically and to discuss the value of a modified therapeutic approach. Our experience covers 349 esophageal resections performed between 1979 and 1992. These patients were predominantly males (93%) with squamous cell carcinoma (86%). The majority of the patients underwent either an Ivor-Lewis (52%) or an Akiyama procedure (36%). Survival was estimated according to the Kaplan-Meier model. Influence of parameters such as sex, histology, type of resection and TNM-staging was assessed with the "log-rank" test. The perioperative mortality was 10%. The non-fatal morbidity rate was 34%, and was most often related to anastomotic leaks. Pathological staging disclosed a majority of T3 tumors (71%). The overall survival rate was 54% at one year, 28% at 2 years and 9% at 5 years. This survival was not influenced by either histology (squamous cell or adenocarcinoma), the type of resection (Ivor-Lewis or Akiyama procedure). A slightly superior survival rate was observed after Ivor-Lewis procedure and is explained by a lower postoperative complication rate. In particular, diffuse N2 disease (abdominal and mediastinal) had a worse prognosis than localized N2. N1 disease was probably understaged, since survival was comparable to localized N2. The natural history was characterized by development of metastases (43%) rather than by local recurrence. We conclude that these results may justify surgery for palliation of dysphagia in so far as the post-operative morbidity is reduced, as we observed with Ivor-Lewis procedures. However, improvement of long-term survival requires a multimodality oncologic approach.

[Surgical treatment of pulmonary and bronchial aspergilloma].

From 1974 to 1990, 61 patients were admitted for pulmonary (55) or bronchial (6) aspergilloma; 50 were treated by surgery. Operative treatment was mandatory because of disabling symptoms in 17 patients, rapid growth on radiological survey in 7 others, diagnostic doubt in 10 and association with bronchogenic cancer in 2. 14 were operated on in order to prevent evolutive complications. Complete resection was possible in 39 patients: with lobectomy or segmentectomy in 34 and with pleuro-pneumonectomy in 5. In 10 others, respiratory failure only allowed speleotomy and thoracoplasty. One thoracotomy was exploratory because of an associated unresectable cancer. Postoperative complications frequently occurred with pulmonary aspergilloma: 4 postoperative deaths, 33 experienced non-fatal complications (28 major bleedings, 16 rehabititation defects, 6 empyemas, 5 respiratory failures). Nevertheless, among 10 patients with either bronchial aspergilloma or pulmonary aspergilloma without underlying disease, only one had a complicated outcome. In conclusion, surgical treatment is well tolerated in the absence of underlying parenchymal disease. However, despite the major operative risk, surgery remains the only efficient treatment in symptomatic patients.

Bronchogenic cancer associated with head and neck tumors. Survival analysis of 194 patients.

We reviewed a series of 194 lung opacities presumed to be bronchogenic carcinomas occurring either simultaneously with (n = 46) or metachronously to (n = 148) a head and neck cancer. The purpose of the study was to evaluate the operative mortality and morbidity and to assess with a survival analysis whether the lung lesions actually were primary carcinomas or metastases of the head and neck cancer. Operation was contraindicated in 77 patients: 36 for metastatic spread, 5 for small-cell carcinoma, and 35 for respiratory insufficiency. The remaining 118 underwent operation: lobectomy for 82, pneumonectomy for 30, wedge resection for 1, and exploratory thoracotomy for 5. The operative mortality was 5%, and the nonfatal morbidity was 22%. The survival at 5 years for patients who underwent operation for bronchogenic cancer was 19.7% (27.2% for stage I, 19% for stage II, 4.5% for stage IIIA, and 0% for stage IIIB). The survival of these patients was not significantly different with respect to the synchronous or metachronous occurrence or the histologic classification (squamous or non-squamous). We conclude that, despite the poor survival, several of these lung lesions associated with a head and neck cancer were most likely a primary bronchogenic cancer. Surgical management is justified because of the observed postoperative mortality.

Pleuropulmonary aspergilloma: clinical spectrum and results of surgical treatment.

From 1974 to 1991, 77 patients were admitted for pulmonary (55), pleural (16), or bronchial (6) aspergilloma. About 50% were asymptomatic. Sixty-three underwent operation. Pulmonary aspergillomas were operated on for therapeutic need in 26 and on principle in 18; the procedures were 28 lobar or segmental resections, 10 thoracoplasties, and 5 pleuropneumonectomies (1 patient had exploration only). Pleural aspergillosis was treated by operation on principle in 5 and for therapeutic need in 8 patients; 10 thoracoplasties, 1 attempt at pleuropneumonectomy, and 2 decortications were performed. All six bronchial lesions were operated on as a rule. Overall postoperative mortality was 9.5%. Major complications were bleeding (n = 37), pleural space problems (n = 24), respiratory failure (n = 6), and postpneumonectomy empyema (n = 4). All patients with pleural disease experienced complications. The outcome was better after lobar or segmental resection than after thoracoplasty (mortality, 6% versus 15%). Asymptomatic and nonsequellary pulmonary or bronchial aspergilloma also had an improved outcome. We conclude that operation is at low risk in pulmonary or bronchial locations in asymptomatic patients and in the absence of sequellae; the risk is high in symptomatic patients for whom operation is the only definite treatment. Pleuropneumonectomy should be avoided. Only symptomatic pleural aspergilloma should be operated on.

[Lobectomy extended to the main bronchus in the treatment of bronchial cancer (seventy-three cases)].

Sleeve allow excision of bronchial carcinoma in patients not able to functionally tolerate pneumonectomy. Our series consists of 73 patients operated over the last thirty years. Implantation of the bronchus was treated either by wedge resection or by complete resection followed by reimplantation. This procedure was performed for respiratory functional reasons in 39 cases (53%), on principle in 27 cases (37%) and in palliative indications in 7 cases (10%). The high perioperative mortality (6.8%) and morbidity (20%) were related to bronchovascular complications which were eliminated over the last decade. Local recurrences (23%) were more frequent than following conventional resections. On the other hand, the survival, 80% at one year, 62% at 2 years, 54% at 3 years and 39% at 5 years, related more to metastatic dissemination than to local recurrence, was comparable to that of the control group of pneumonectomised patients. This procedure gave identical results in terms of survival, but should be reserved for patients with respiratory failure due to the increased risk of local recurrence.

[Forgotten mediastinal goiter: seven cases].

The authors relate their experience with 7 cases of mediastinal goiter residual to a subtotal thyroidectomy for substernal goiter. The differential diagnosis with ordinary recurrence was based on the absence of connection with the cervical remnant. The reasons for surgical decision-making was mediastinal compression in 4 patients, hyperthyroidism in 1 patient and absent diagnosis in 1 patient; surgery was systematic in 1 asymptomatic patient. Sternal splitting incision was required in 6 patients: alone in 3, associated with cervical incision in 3 others; excision by an exclusively cervical route was possible in one patient. No malignancy was discovered. Postoperative outcome was uncomplicated in all patients. The residual goiter has the same clinical and paraclinical presentation as the ordinary intrathoracic goiter; treatment should be principally surgical for the same reasons. Nevertheless, for this mediastinal tumor, sternum-splitting incision will be required in most cases.

[Diaphragmatic hernia complicating omentoplasty after thoracic wall excision. Reflections apropos of 2 cases].

The authors relate two case-reports of diaphragmatic hernia occurring after antero-lateral chest-wall resection and repair with an omental flap. Both patients had undergone a prior lung resection for bronchogenic cancer, and the indication for chest-wall resection was parietal neoplastic recurrence. In both patients, the omental flap was brought up to the chest wall defect by a direct transdiaphragmatic route; prosthetic material was note used. The hernia presented once as early post-operative evisceration, and once as proximal obstruction due to gastric herniation. The causes of these two complications are analysed. Omentoplasty was justified twice, since the latissimus dorsi had been severed during the prior thoracotomy. Prosthetic material might have been useful to one of the patients, but not to the second who had undergone pneumonectomy. The transdiaphragmatic passage of the omentoplasty was certainly responsible for the herniae and should be avoided.

[Complications and mortality of surgery for bronchogenic cancers].

Resection surgery for lung cancer is beset with specific or non-specific complications which often darken the prognosis for life. The specific complications, related to surgical dissections, are mainly per- and postoperative haemorrhages of various origins and, less frequently, disturbances in respiration, nerve wound or chylothorax. Soon after pneumonectomy a bronchial fistula encouraged by different factors may appear (3.3% of the cases) and empyema, usually caused by staphylococci, may develop (3%). Non-specific complications may disturb the post-resection period, involving the lungs (atelectasia, parenchymal infections, acute respiratory failure) or the cardiovascular system (pulmonary embolism, dysarrhythmia). The overall perioperative mortality rate has decreased with time owing to advances in anaesthesia and intensive care: in the hands of certain medico-surgical teams it does not exceed 3%. It is significantly lower in lobar (mean: 4.5%) than in pulmonary (mean: 8.4%) resections. Enlarged resections and lymph node dissections are aggravating factors. Patients aged 70 or more do not tolerate these operations so well: their mean overall mortality rate is twice that observed in younger patients (8% on average and up to 20%). Resection surgery for lung cancer remains a necessarily hazardous procedure but is the only treatment that can cure the patient. Its success is directly conditioned by a good preoperative risk evaluation.

Emergency repair of main stem bronchus disruption complicated by anastomotic stenosis: two cases of successful repair by resection and reanastomosis.

The case reports of two patients who developed complete bronchial stenosis after emergency repair of a left stem bronchus disruption are reported. Resection of the stenotic bronchus and reanastomosis restored a normal lung function in both patients. Arguments for a conservative approach, perioperative investigations, and technical data are discussed.

[Non-aplastic N2 operated bronchial cancers. Multifactorial analysis of the prognosis].

The marked disparity of the published 5-year survival rates (0 to 3%) for non-anaplastic, operated N2 lung cancers would suggest the marked heterogeneity of the patients studied. We prospectively studies 97 N2 tumours for which "curative" resection was performed between 1983 and 1986. The overall survival rate was 28% at 3 years, 19% at 4 years and 12% at 5 years. Survival was studied on the basis of several parameters concerning the tumour: histological type and degree of differentiation, T (TNM), modality of invasion (circumscribed, infiltrating), the quality of the stroma (absent, fibrotic, cellular), the mitotic index, the necrosis rate, presence or absence of microscopic invasion of blood vessels; and concerning the nodes: site, number (solitary, multiple), size of the metastasis (massive, microscopic), macroscopic or microscopic invasion of the capsule. We know the outcome for all of our patients: 81 have died and 16 are still alive. Sixty-one have developed metastases, 5 have developed local and regional recurrences and 3 have both a recurrence and metastases. Univariate analysis demonstrated that a small number of parameters significantly influence survival: microscopic invasion of blood vessel (chi 2 = 5.24, p less than 0.02), macroscopic and microscopic invasion of the lymph node capsule. In order to more clearly define the prognostic factors, we used Cox's multidimensional model. This model was applied to the three significant parameters to which we added two other variables which non-significantly tended to be related to survival: tumour necrosis and number of lymph nodes involved.(ABSTRACT TRUNCATED AT 250 WORDS)

[The risks of surgical training. A study apropos of 348 pneumonectomies].

On the basis of the retrospective study of a series of 348 pneumonectomies, the authors have attempted to assess whether the risks of postoperative complications were increased if the operation was carried out by trainee surgeons. All operations were performed for cancer, with a stapler being used for bronchial suture. The patients were classified in three groups according to the surgeon: 133 (38%) were operated by an University professor (group I, 2 surgeons), 171 (49%) by chief resident or hospital practitioner (group II, 3 surgeons) and 44 (13%) by an intern (group III, 14 surgeons). The homogeneity of the 3 groups was checked with alpha X2 test. The study dealt with the overall mortality as well as with the specific complications of pneumonia, namely empyema and bronchopleural fistulae. The overall postoperative mortality rate was similar in the 3 groups (respectively 8%, 8% and 5%), as well as the occurrence of empyema (respectively 4%, 3% and 5%). A difference that, though not significant statistically, is not negligible, appears for bronchopleural fistulae, which complicate 9% of the operations carried out by interns vs. 4% in the other 2 categories. These observations challenge a number of studies claiming that surgery performed by inexperienced surgeons is innocuous. However, pneumonectomy is an essential step in the training to thoracic surgery, so that no candidate with sufficient surgical maturity should be prevented from performing it.

[Exploratory thoracotomy of necessity in surgery of bronchial cancer].

The survey conducted by the French Language Society of Thoracic and Cardiovascular Surgery collected a total of 2,962 exploratory thoracotomies for lung cancer performed over a period of 10 years. Over the same period, 25,291 operations were performed for lung resection, so that the mean rate of exploratory thoracotomy was therefore 11.7%. The rate of exploratory thoracotomy varied from one unit to another (2.7% to 45.8%) and appeared to be virtually independent of the operative activity. It has continued to decrease over time, which is even more significant in view of the fact that the operative activity has increased in all of the units. The local and regional spread of the tumour represents the principal reason for non-resection (79% of cases); it was less common in units with a high operative activity (72%) than in other units (84%) especially when the mediastinal lymph nodes were involved. The major thoracic surgery units also appear to be distinguished by a greater audacity, as well as an increased failure rate in the case of tumour spread to the trachea. The risk of exploratory thoracotomy is considerable as it was responsible for death in 3% of cases. A better radiological and clinical assessment, rather than the use of mediastinoscopy should avoid 2% of these useless explorations. The subsequent course of these patients barely concerns the surgeon: it is rapidly unfavourable and the rare long-term survivals (2% at five years) are not sufficient to justify operation at any cost.
