RESUMO
We report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for patients with pathologically staged cancer of the esophagus and esophagogastric junction after resection or ablation with no preoperative therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted de-identified data using standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 13,300 patients, 5,631 had squamous cell carcinoma, 7,558 adenocarcinoma, 85 adenosquamous carcinoma, and 26 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (51%), little weight loss (1.8 kg), 0-2 ECOG performance status (83%), and a history of smoking (70%). Cancers were pT1 (24%), pT2 (15%), pT3 (50%), pN0 (52%), pM0 (93%), and pG2-G3 (78%); most involved distal esophagus (71%). Non-risk-adjusted survival for both squamous cell carcinoma and adenocarcinoma was monotonic and distinctive across pTNM. Survival was more distinctive for adenocarcinoma than squamous cell carcinoma when pT was ordered by pN. Survival for pTis-1 adenocarcinoma was better than for squamous cell carcinoma, although monotonic and distinctive for both. WECC pathologic staging data is improved over that of the 7th edition, with more patients studied and patient and cancer variables collected. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics, and should direct 9th edition data collection. However, the role of pure pathologic staging as the principal point of reference for esophageal cancer staging is waning.

To address uncertainty of whether clinical stage groupings (cTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for clinically staged patients from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 22,123 clinically staged patients, 8,156 had squamous cell carcinoma, 13,814 adenocarcinoma, 116 adenosquamous carcinoma, and 37 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (18.5-25 mg/kg2 , 47%), little weight loss (2.4 ± 7.8 kg), 0-1 ECOG performance status (67%), and history of smoking (67%). Cancers were cT1 (12%), cT2 (22%), cT3 (56%), cN0 (44%), cM0 (95%), and cG2-G3 (89%); most involved the distal esophagus (73%). Non-risk-adjusted survival for squamous cell carcinoma was not distinctive for early cT or cN; for adenocarcinoma, it was distinctive for early versus advanced cT and for cN0 versus cN+. Patients with early cancers had worse survival and those with advanced cancers better survival than expected from equivalent pathologic categories based on prior WECC pathologic data. Thus, clinical and pathologic categories do not share prognostic implications. This makes clinically based treatment decisions difficult and pre-treatment prognostication inaccurate. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient characteristics, cancer categories, and treatment characteristics and should direct 9th edition data collection.

To address uncertainty of whether pathologic stage groupings after neoadjuvant therapy (ypTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for pathologically staged cancers after neoadjuvant therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 7,773 pathologically staged neoadjuvant patients, 2,045 had squamous cell carcinoma, 5,686 adenocarcinoma, 31 adenosquamous carcinoma, and 11 undifferentiated carcinoma. Patients were older (61 years) men (83%) with normal (40%) or overweight (35%) body mass index, 0-1 Eastern Cooperative Oncology Group performance status (96%), and a history of smoking (69%). Cancers were ypT0 (20%), ypT1 (13%), ypT2 (18%), ypT3 (44%), ypN0 (55%), ypM0 (94%), and G2-G3 (72%); most involved the distal esophagus (80%). Non-risk-adjusted survival for yp categories was unequally depressed, more for earlier categories than later, compared with equivalent categories from prior WECC data for esophagectomy-alone patients. Thus, survival of patients with ypT0-2N0M0 cancers was intermediate and similar regardless of ypT; survival for ypN+ cancers was poor. Because prognoses for ypTNM and pTNM categories are dissimilar, prognostication should be based on separate ypTNM categories and groupings. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics and should direct 9th edition data collection.

BACKGROUND: To assess the outcome of surgical resection in patients with primary mediastinal nonseminomatous germ-cell tumors (PMNSGCT) with rising serum tumor markers (STM) following standard platinum-based chemotherapy. PATIENTS AND METHODS: A total of 158 consecutive patients with PMNSGCT who received platinum-based chemotherapy followed by complete surgical extirpation of residual disease at Indiana University from 1982 to 2007 were retrospectively reviewed. Thirty-five of these 158 patients had rising STM at time of resection. RESULTS: Thirty-five patients (34 males and 1 female) comprise the basis of this report. Three patients had rising human chorionic gonadotropin, and the remaining 32 patients had rising alpha-fetoprotein at the time of thoracic surgery. Twenty-four of the 35 (69%) pathologically demonstrated viable germ-cell tumor, while 8 patients had teratoma and 3 patients had necrosis only at time of resection, despite the presence of rising STM. Twenty-seven patients normalized their tumor markers postoperatively. Twenty-one of 35 died, 5 were lost to follow-up, and 9 are alive. Of the nine patients alive, seven are continuously disease free with median follow-up of 64 months (range 25-220 months). CONCLUSION: The presence of rising STM doesn't preclude successful therapy with surgical resection, especially if carried out by experienced thoracic surgical oncologists.

The aim of this study is to report assemblage of a large multi-institutional international database of esophageal cancer patients, patient and tumor characteristics, and survival of patients undergoing esophagectomy alone and its correlates. Forty-eight institutions were approached and agreed to participate in a worldwide esophageal cancer collaboration (WECC), and 13 (Asia, 2; Europe, 2; North America, 9) submitted data as of July 1, 2007. These were used to construct a de-identified database of 7884 esophageal cancer patients who underwent esophagectomy. Four thousand six hundred and twenty-seven esophagectomy patients had no induction or adjuvant therapy. Mean age was 62 +/- 11 years, 77% were men, and 33% were Asian. Mean tumor length was 3.3 +/- 2.5 cm, and esophageal location was upper in 4.1%, middle in 27%, and lower in 69%. Histopathologic cell type was adenocarcinoma in 60% and squamous cell in 40%. Histologic grade was G1 in 32%, G2 in 33%, G3 in 35%, and G4 in 0.18%. pT classification was pTis in 7.3%, pT1 in 23%, pT2 in 16%, pT3 in 51%, and pT4 in 3.3%. pN classification was pN0 in 56% and pN1 in 44%. The number of lymph nodes positive for cancer was 1 in 12%, 2 in 8%, 3 in 5%, and >3 in 18%. Resection was R0 in 87%, R1 in 11%, and R2 in 3%. Overall survival was 78, 42, and 31% at 1, 5, and 10 years, respectively. Unlike single-institution studies, in this worldwide collaboration, survival progressively decreases and is distinctively stratified by all variables except region of the world. A worldwide esophageal cancer database has been assembled that overcomes problems of rarity of this cancer. It reveals that survival progressively (monotonically) decreased and was distinctively stratified by all variables except region of the world. Thus, it forms the basis for data-driven esophageal cancer staging. More centers are needed and encouraged to join WECC.

The records of 288 patients undergoing isolated surgical myocardial revascularization between June 1989 and September 1992 were reviewed to determine the relative risk associated with surgery after an acute myocardial infarction (MI). A total of 73 patients (25 percent) were operated on within 30 days of an acute infarction while 215 patients (75 percent) had no history of recent infarction. Patients with an acute infarction were more likely to have regional wall motion abnormalities on ventriculography (mean wall score 6.7 vs 4.9, p = 0.001), require preoperative balloon pumping (15.1 percent vs 5.6 percent, p = 0.01), and have recent symptoms of congestive heart failure (23 percent vs 12 percent, p = 0.02). Patients with an acute MI also had higher NYHA functional classification and greater urgency of surgery. Despite these differences, overall mortality was lower in the acute MI group than in the control population (1.4 percent vs 2.3 percent, p = 0.623). Weaning from bypass was not appreciably more difficult in patients with an acute MI, nor were there differences in the mean number of hours of balloon pump or inotrope support.

PURPOSE: This study investigated the association of COPD and postoperative cardiac arrhythmias, specifically supraventricular tachycardia (SVT), as well as mortality in patients undergoing pulmonary resection for non-small cell lung cancer (NSCLC). METHODS: A retrospective chart review of 244 patients who had undergone lung resection for NSCLC at Indiana University Hospital between 1992 and 1997 was undertaken. COPD, which was defined as an FEV(1) of < or = 70% predicted and an FEV(1)/FVC ratio of < or = 70% based on the results of a preoperative pulmonary function test (PFT), was diagnosed in 78 of the 244 patients (COPD group). In the remaining 166 patients, the results of preoperative PFTs did not meet these criteria (non-COPD group). Both groups were otherwise well-matched with respect to multiple variables, including age, comorbid conditions, extent of pulmonary resection, and final pathologic stage. The incidence of cardiac arrhythmias and operative mortality were compared between the two groups using univariate and multivariate analysis. RESULTS: Seventy-six patients (31.9%) experienced new onsets of postoperative SVT, with 58 of these patients (76.3%) demonstrating atrial fibrillation. The COPD group had a 58.7% incidence of SVT (n = 44) compared to a 27.0% incidence (n = 44) in the non-COPD group (p < 0.0 0 1). Moreover, following initial digoxin therapy, the COPD group required more second-line antiarrhythmic therapy than did the non-COPD group (66.7% vs 37.8%, respectively; p = 0.0 03). Overall, there were 16 operative deaths (6.6%), and the mortality rate was significantly higher in the COPD group (14.1%) than in the non-COPD group (3.0%; p = 0.0 04). Patients who developed SVT had a significantly longer hospital course than did patients who did not (p < 0.0001). Thirteen of the 16 patients who died experienced SVT; however, SVT was not an independent risk factor for death. Finally, of the 19 variables evaluated, major resection (ie, pneumonectomy and bilobectomy) and COPD were identified as independent risk factors for the development of cardiac arrhythmias (p = 0.0 033 and p = 0.0 009, respectively). CONCLUSION: Patients with COPD, as defined by the results of preoperative PFTs, are at significantly higher risk for SVT, and in particular SVT refractory to digoxin, following pulmonary resection for NSCLC. Although SVT was not an independent risk factor for death, a significantly longer hospitalization was observed.

Before cisplatin-based chemotherapy, long-term survival after resection of primary mediastinal nonseminomatous germ cell tumors was unusual. We reviewed the case histories of 48 patients who underwent multimodality treatment for mediastinal nonseminomatous germ cell tumor between 1976 and 1988. Twenty-eight patients received initial therapy at Indiana University and 20 were referred after having had unsuccessful initial therapy elsewhere. In 44 patients (92%) the levels of either one or both serum tumor markers were elevated at the time of diagnosis. Five patients had choriocarcinoma, three embryonal carcinoma, 12 yolk sac carcinoma, four teratocarcinoma, 22 mixed cell type, and two had an unclassified type. Twenty-two of the 28 patients in our initial therapy group had a complete response to treatment, as defined by normal serum tumor markers and absence of residual tumor. In this group, 16 patients had resection of residual disease after chemotherapy, four had total or near total resection before chemotherapy, and only two had chemotherapy alone. Seventeen patients are surviving after this treatment with a median survival of 64 months and a 57% 5-year Kaplan-Meier survival rate. Only two of the 20 patients who were referred for salvage chemotherapy had a complete response. Both required resection of residual disease after salvage chemotherapy. Only one patient survived after this treatment. There was no significant treatment morbidity or mortality. A multimodality approach to primary mediastinal nonseminomatous germ cell tumor with intensive cisplatin-based chemotherapy, emphasis on normalizing serum tumor markers, and aggressive resection of residual disease now offers survival to a significant number of patients.

The standard palliation of malignant pleural effusions involves tube thoracostomy drainage with chemical pleurodesis. The insufflation of intrapleural talc under thoracoscopic guidance (n = 39) was evaluated against documented controls that consisted of patients (n = 85) who participated in a randomized study with tube thoracostomy drainage followed by either bleomycin or tetracycline sclerosis. Under local anesthesia, which was supplemented by intravenous sedation, patients in the talc group underwent complete pleural fluid evacuation. The talc was then insufflated evenly on the entire pleural surface under thoracoscopic guidance. Of the patients in the talc group who survived their disease process, 97% had a successful pleurodesis at 30 days and 95% at 90 days. In comparison, the bleomycin group demonstrated a success rate of 64% at 30 days and 70% at 90 days (p = 0.003 and p = 0.047 versus the talc group). The tetracycline group had successful pleurodesis in only 33% at 30 days and 47% at 90 days (p < 0.001 and p < 0.001 versus the talc group). There were only two patients in the talc group in whom pleurodesis was not successful, and both were subsequently found to have extraluminal compression of the right lower lobe bronchus, which prevented lung reexpansion. These data demonstrate that the insufflation of talc into the pleural cavity under thoracoscopic guidance is a safe and efficacious procedure in the control of malignant pleural effusions.

From 1972 to 1987, seven patients, from two to 28 months of age, underwent left subclavian artery-left coronary artery anastomosis for anomalous origin of the left coronary artery from the pulmonary trunk. All of these infants, median age 4 months, had severe congestive heart failure caused by anterolateral myocardial infarctions. There were two hospital deaths (29% mortality rate) with no late deaths after an average 10-year follow-up. All survivors have good exercise tolerance New York Heart Association class I), reduction in heart size, and significant improvement or normalization of ventricular function by echocardiography. Patency of the subclavian-left coronary artery anastomosis has been documented in two of four patients who have undergone catheterization. In contrast to other revascularizing procedures for treatment of an anomalous origin of the left coronary artery, anastomosis of the left subclavian to the left coronary artery may be performed without cardiopulmonary bypass or aortic occlusion. Moreover, this procedure appears to have an acceptable mortality rate with excellent long-term functional results in critically ill infants.

Congenital tracheal stenosis may be a life-threatening anomaly not relieved by airway intubation. Over the past 7 years, anterior pericardial tracheoplasty has been used at our institution for treatment of congenital long-segment tracheal stenosis in infants with impeding airway obstruction. Case histories of eight patients undergoing nine anterior pericardial tracheoplasties have been reviewed to assess this technique. Of these patients, six have required preoperative tracheal intubation before repair to maintain ventilation. The surgical technique of anterior pericardial tracheoplasty includes a median sternotomy approach with partial normothermic cardiopulmonary bypass. An anterior tracheotomy through all hypoplastic rings allows enlargement with autologous pericardium to 1.5 times the predicted normal diameter. After insertion, the pericardium and hypoplastic tracheal cartilages are suspended to surrounding mediastinal structures, which prevents airway collapse. Seven of eight infants have survived without tracheoplasty dehiscence or wound infections. Five were ultimately extubated and are currently free of symptoms from 6 months to 5 years after anterior pericardial tracheoplasty. The other two survivors had residual stenosis as a result of complications of prior tracheostomy. One of these patients has undergone a successful second anterior pericardial tracheoplasty and is currently extubated and well. The other is palliated at 6 months with a tracheostomy awaiting a second anterior pericardial tracheoplasty. Our review of anterior pericardial tracheoplasty has demonstrated the safety, utility, and at least medium-term benefit of this procedure in infants of any age and weight.

BACKGROUND: Although the sternoclavicular joint is an unusual site for infection, thoracic surgeons may preferentially be called on to coordinate management of cases refractory to antibiotic therapy because of the anatomic relationship of this joint to major vascular structures. METHODS: Since 1994 we have surgically managed nine sternoclavicular joint infections in eight patients. Associated medical problems were frequent and included diabetes mellitus (n = 2), end-stage renal disease (n = 2), hematologic disorders (n = 2), and multiple joints affected by sepsis (n = 4). Open joint exploration with drainage and débridement with the use of general anesthesia was performed in four patients. The remaining four patients (one with bilateral sternoclavicular joint infections) had computed tomographic evidence of diffuse joint and surrounding bone destruction with infection extending into mediastinal soft tissues. Surgical therapy for these five joint infections involved en bloc resection of the sternoclavicular joint with an ipsilateral pectoralis major muscle covering the bony defect. RESULTS: There were two deaths unrelated to the surgical procedure. After a mean follow-up of 20 months, the remaining six survivors (seven joints) have complete healing with no apparent limitation in the range of motion even after en bloc resection. CONCLUSIONS: Most cases of early sternoclavicular joint infections will respond to conservative measures. However, when radiographic evidence of infection beyond the sternoclavicular joint is present, en bloc resection, although seemingly aggressive, results in immediate eradication of all infection with negligible functional morbidity. Prolonged antibiotic therapy or continued local drainage procedures appear to have little value in these cases, adding only to patient care costs and the potential sequelae of chronic infections.

OBJECTIVES: The treatment of nonseminomatous germ cell tumors with cisplatin-based chemotherapy followed by aggressive surgical resection of residual disease is one of the most successful models for multimodality cancer therapy. We reviewed the case histories of 91 patients treated at our institution from 1981 to 1998 with primary mediastinal nonseminomatous germ cell tumors to evaluate variables that may influence survival after surgery. METHODS: Twelve of the 91 patients did not undergo postchemotherapy resection because of progressive disease. Seventy-nine of them underwent 82 thoracic surgical procedures and are the basis of this review. The majority (71/75) had elevated serum tumor markers, 75% (n = 50) of which returned to normal levels after first- or second-line chemotherapy. RESULTS: There were 3 operative deaths and 1 late death, attributed to pulmonary complications. Twenty-four patients died of recurrent disease and 3 of leukemia, for an overall survival of 61% after an average follow-up of 48 months. The pathologic findings of complete tumor necrosis (n = 19) and benign teratoma (n = 28) in the surgical specimen predicted excellent and good long-term survival, respectively, which was statistically better than that of patients having persistent nonseminomatous germ cell tumors (n = 24) or carcinomatous/sarcomatous degeneration (n = 8). CONCLUSIONS: Primary nonseminomatous germ cell tumors of the mediastinum can be cured with a multimodality therapy, particularly in the subset of patients with postchemotherapy pathologic findings of tumor necrosis and teratoma. Survival is poor but possible in patients with unfavorable pathologic findings after chemotherapy, currently justifying an aggressive surgical approach in patients with otherwise operable disease.

To determine the efficacy of ventricular closure techniques, we reviewed our experience with 62 patients who survived the repair of aneurysms of the anterior wall of the left ventricular from 1984 through 1989. Forty of these patients underwent aneurysm repair by standard linear closure and 22 by a circular closure technique. After a mean follow-up interval of 3 years, there were no demonstrable differences in angina class, New York Heart Association functional classification, or survival. In 41 surviving patients, postoperative left ventricular dimensions and function were satisfactorily evaluated by standard echocardiographic measurements. No significant differences were found in postoperative long-axis left ventricular systolic diameter or in short-axis systolic or diastolic areas. There was a significantly larger long-axis diastolic diameter in the circular closure group; however, there was no difference in this parameter when the ratios of postoperative to preoperative lengths were compared. Further intragroup comparisons demonstrated an increase in short-axis areas postoperatively within the circular closure group in contrast to a decrease in patients in the linear closure group; these changes were not statistically significant. There was no significant difference in postoperative ejection fraction between the two closure groups, although minor reductions were found in the circular closure group. These data demonstrate no significant difference between the linear and circular closure techniques with respect to standard echocardiographic parameters, functional classification, and survival.

Creation of a competent left atrioventricular valve is a cornerstone in surgical repair of complete atrioventricular septal defects. To identify risk factors for mortality and failure of left atrioventricular valve repair and to determine the impact of cleft closure on postoperative atrioventricular valve function, we retrospectively analyzed hospital records of 203 patients between January 1974 and January 1995. Overall early mortality was 7.9%. Operative mortality decreased significantly over the period of the study from 19% (4/21) before 1980 to 3% (2/67) after 1990 (p = 0.03). Ten-year survival including operative mortality was 91.3% +/- 0.004% (95% confidence limit): all survivors are in New York Heart Association class I or II. Preoperative atrioventricular valve regurgitation was assessed in 203 patients by angiography or echocardiography and was trivial or mild in 103 (52%), moderate in 82 (41%), and severe in 18 (8%). Left atrioventricular valve cleft was closed in 93% (189/203) but left alone when valve leaflet tissue was inadequate and closure of the cleft might cause significant stenosis. Reoperation for severe postoperative left atrioventricular valve regurgitation was necessary in eight patients, five of whom initially did not have closure of the cleft and three of whom had cleft closure. Six patients had reoperation with annuloplasty and two patients required left atrioventricular valve replacement. Five patients survived reoperation and are currently in New York Heart Association class I or II. On most recent evaluation assessed by angiography or echocardiography (a mean of 59 months after repair), left atrioventricular valve regurgitation was trivial or mild in 137 of the 146 survivors (94%) examined; none had moderate or severe left atrioventricular valve stenosis. By multiple logistic regression analysis, strong risk factors for early death and need for reoperation included postoperative pulmonary hypertensive crisis, immediate postoperative severe left atrioventricular valve regurgitation, and double-orifice left atrioventricular valve. These results indicate that complete atrioventricular septal defects can be repaired with low mortality and good intermediate to long-term results. Routine approximation of the cleft is safe and has a low incidence of reoperation for left atrioventricular valve regurgitation.

Acute myocarditis is usually a self-limiting viral illness. Rarely, however, myocardial depression can be profound leading to circulatory collapse. Mechanical cardiac support in the form of intraaortic balloon pumps or ventricular assist devices have been used in these unusual cases to maintain systemic perfusion until transplantation or left ventricular recovery occurs. We report a young patient with acute myocarditis who required left heart mechanical support and who, however, was successfully weaned despite only minimal myocardial recovery.

Triple-drug immunosuppression with OKT3 induction is effective rejection prophylaxis in pediatric cardiac allograft recipients. The concerns regarding prevalent lymphoproliferative disease, growth retardation, cytomegalovirus, and other opportunistic infections have not been realized. Since June 1986, 34 pediatric patients, 23 males and 11 females, (age 4 days to 15 years) have undergone orthotopic heart transplantation at our institution. Fifteen patients were less than 6 months old and 13 had type I or II hypoplastic left heart syndrome. There have been four (12%) operative and four (12%) late deaths and a survival rate of 76% after a mean follow-up of 33 months (range, 1 to 82 months). The only deaths attributed to allograft rejection occurred in two newborn recipients (2 and 10 months after surgery) who neither received maintenance steroids nor underwent routine biopsy. The only death from infection (pneumococcus) occurred 6 months after surgery in a 4-year-old patient who was not known to be asplenic. Of the 27 long-term (> 1 year) survivors, 17 (68%) had an average of two rejection episodes during the follow-up period, 10 patients (32%) have been free of graft rejection, and 26 patients (96%) have not experienced a cytomegalovirus infection despite OKT3 induction therapy. Two patients developed lymphoproliferative disease, one of whom was successfully treated by transient reduction of immunosuppression. The other patient died 13 months after transplantation of a lymphoma of the central nervous system. All survivors have demonstrated satisfactory increases in mean height and weight.(ABSTRACT TRUNCATED AT 250 WORDS)

Our institution performed an orthotopic heart transplantation in a patient with Marfan's syndrome. The immediate postoperative course was complicated with ultimate discharge; however, this patient died within 1 year as a result of an aortic dissection. On the basis of our experience, we surveyed all heart transplant centers listed with the North American Transplant Coordinator Organization for other patients with Marfan's syndrome who had been referred for transplantation. Nearly one third of responding centers evaluated a total of 30 patients with Marfan's syndrome. Of these, only 13 were formally listed for a donor organ and 11 underwent heart transplantation with an operative mortality of 9.1% (n = 1). Posttransplantation morbidity was significant and includes a 40% (n = 4) incidence of thoracic aorta dissection (one fatal) in operative survivors. There were three other non-dissection-related late deaths for an overall survival of 54.4% after a mean follow-up of 33.0 months. In this shared experience, it appears that the known vascular complications of Marfan's syndrome may diminish the anticipated results after heart transplantation. The reluctance to place these patients on heart transplant donor waiting lists can be justified.

Congenital bronchoesophageal fistulas in the adult age group are rare, with only approximately 20 cases having been recognized. All of these cases have been an isolated esophageal anomaly without other associated esophageal pathology. We present an interesting case of an adult with both symptomatic congenital bronchoesophageal fistula and proximal esophageal web.

Bronchoplastic surgical techniques may allow resectional therapy for non-small cell lung carcinoma in select patients in whom preoperative pulmonary function demonstrates prohibitive risk for pneumonectomy. We report an otherwise poor candidate for pneumonectomy in whom coronal magnetic resonance imaging demonstrated the potential for distal bronchial salvage.
