Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Small pleural effusions that cannot be assessed by thoracentesis prior to surgery may represent a diagnostic challenge in the patient with a resectable, non-small cell cancer of the lung. Even if the effusion is drained preoperatively and analyzed, the cytology may be falsely negative. We have found that careful inspection of pleural effusions using a single small 2-cm incision and video-assisted thorascopy may reveal a gelatinous piece of clotlike material that resembles a jellyfish. This cohesive particulate piece of material lies in the effusion. This material can be sent for frozen section (unlike cytologic exams in most hospitals), and an immediate answer can be obtained. Cytology results of the surrounding effusion that return 24 hours later confirm the frozen section findings. If malignant, this avoids thoracotomy and pulmonary resection in a patient with unsuspected T4, stage IIIB lung cancer. It also avoids closing a patient with an unsuspected effusion and having to wait 24 hours for the cytology results. We review our experience with this jellyfish-like material.

Abstract
OBJECTIVE We streamlined our care after pulmonary resection for quality and cost-effectiveness. METHODS A single surgeon performed 500 consecutive pulmonary resections through a thoracotomy over a 2(3/4)-year period in a university setting. Patients were extubated in the operating room and sent directly to their hospital room. Chest tubes were placed to water seal and removed on postoperative day 2 if there was no air leak and drainage was less then 400 mL/d. Epidural catheters were used and removed by postoperative day 2. The plan for each day and discharge on postoperative day 3 or 4 was reviewed with the patients and families daily during rounds. The patient went home the day the last chest tube was removed. Persistent air leaks were treated with Heimlich valves. RESULTS There were 500 patients (338 men), with a median age of 58 years (range, 3-87 years). Of these patients, 293 had pre-existing conditions. Seventy-three (15%) patients had been denied operations by at least one other surgeon. Four hundred nineteen (84%) patients had successful placement of a functioning preoperative epidural catheter. Pneumonectomy was performed in 32 (6%) patients, segmentectomy was performed in 16 (3%) patients, and lobectomy, sleeve lobectomy, and/or bilobectomy was performed in 194 (39%) patients. Nonanatomic resections were performed for metastasectomy. This included a single wedge resection in 161 (32%) patients and multiple wedge resections in 97 (19%) patients. A total of 482 (96%) patients were extubated in the operating room, and 380 (76%) patients were sent to their hospital room. The remaining 120 patients went to the intensive care unit for a median of 1 day (range, 1-41 days). Complications occurred in 107 (21%) patients, and operative mortality was 2.0%. Median day of discharge was postoperative day 4 (range, 2-119 days). A total of 327 (65%) patients left the hospital on postoperative day 4 or sooner. By survey, 97% of patients had excellent or good satisfaction with their care at hospital discharge, and 91% were extremely happy or satisfied at the 2-week follow-up contact. CONCLUSIONS Most patients who undergo elective pulmonary resection can be extubated immediately after the operation, go directly to their room and avoid the intensive care unit, be discharged on postoperative day 3 or 4, and have minimal morbidity and mortality with high satisfaction both at discharge and at the 2-week follow-up contact. Techniques that seem to accomplish this include the following: the use of a water seal, removal of epidural catheters on postoperative day 2, early chest tube management, treatment of persistent air leaks with Heimlich valves, and daily reinforcement of the planned events for each day, as well as on the date of discharge with the patients and their families.

Abstract
BACKGROUND Surgeons treat air leaks differently. Our goal was to evaluate whether it is better to place chest tubes on suction or water seal for stopping air leaks after pulmonary surgery. A second goal was to evaluate a new classification system for air leaks that we developed. METHODS Patients were prospectively randomized before surgery to receive suction or water seal to their chest tubes on postoperative day (POD) #2. Air leaks were described and quantified daily by a classification system and a leak meter. The air-leak meter scored leaks from 1 (least) to 7 (greatest). The group randomized to water seal stayed on water seal unless a pneumothorax developed. RESULTS On POD #2, 33 of 140 patients had an air leak. Eighteen patients had been preoperatively randomized to water seal and 15 to suction. Air leaks resolved in 12 (67%) of the water seal patients by the morning of POD #3. All 6 patients whose air leak did not stop had a leak that was 4/7 or greater (p < 0.0001) on the leak meter. Of the 15 patients randomized to suction, only 1 patient's air leak (7%) resolved by the morning of POD #3. The randomization aspect of the trial was ended and statistical analysis showed water seal was superior (p = 0.001). The remaining 14 patients were then placed to water seal and by the morning of POD #4, 13 patients' leaks had stopped. Of the 32 total patients placed to seal, 7 (22%) developed a pneumothorax and 6 of these 7 patients had leaks that were 4/7 or greater (p = 0.001). CONCLUSIONS Placing chest tubes on water seal seems superior to wall suction for stopping air leaks after pulmonary resection. However, water seal does not stop expiratory leaks that are 4/7 or greater. Pneumothorax may occur when chest tubes are placed on seal with leaks this large.

Abstract
Pryce's type I intralobar sequestration, in which a region of lung exhibits tracheobronchial continuity and aberrant systemic arterial supply, is most frequently asymptomatic and discovered incidentally. While hemoptysis may be a common presenting symptom, massive hemoptysis is rarely seen. We document a case of a 58-year-old man, previously asymptomatic, whose initial presentation was that of massive hemoptysis. The radiographic, intraoperative and pathologic findings in our patient confirm that his sequestration was of Pryce's type I. Ann Diagn Pathol 5:91-95, 2001.

Abstract
Bronchopleural fistula (BPF) is a life-threatening complication after pulmonary resection. The incidence varies from 4.5% to 20% after pneumonectomy and is only 0.5% after lobectomy. Certain patient characteristics increase this incidence. These include preoperative radiation to the chest, destroyed or infected lung from inflammatory disease, immunocompromised host, and insulin-dependent diabetes. Certain surgical techniques also increase the incidence. These include pneumonectomy, right-sided pneumonectomy, a long bronchial stump, residual cancer at the bronchial margin, devascularization of the bronchial stump, prolonged ventilation, or reintubation after resection and surgical inexperience. The best treatment of a BPF is prevention. Prevention centers around meticulous surgical technique and the liberal use of prophylactic, pedicled muscle flaps for the patient at increased risk. Survival of BPF depends on a high index of suspicion, early diagnosis, and aggressive surgical intervention.

Abstract
BACKGROUND Removal of the right middle and lower lobes often leaves a pleural space problem that can cause prolonged air leaks. METHODS A single surgeon prospectively randomized 16 patients who underwent bilobectomy. Eight patients had 1200 mL of air injected under the right hemidiaphragm after bilobectomy and 8 did not. The air was injected through a small transdiaphragmatic opening made in the right hemidiaphragm at the time of pulmonary resection. RESULTS The age of the patients, preoperative pulmonary function, preoperative comorbidities, indications for surgery, and final pathology were not significantly different between the two groups. On postoperative day #1, a pneumothorax was present in 1 patient (13%) in the pneumoperitoneum group (P group) and in 4 patients (50%) in the nonpneumoperitoneum group (N-P group). On postoperative day 1, an air leak was present in 1 patient (13%) in the P group and 5 patients (63%) in the N-P group (p < 0.001). By the third postoperative day, no patient in the P group had an air leak; however, a leak was present in 4 patients (50%) in the N-P group (p < 0.001). Median hospital stay in the P group was 4 days (range, 3 to 6 days), compared with 6 days (range, 4 to 8 days) in the N-P group (p < 0.001). Three patients in the N-P group were sent home with a Heimlich valve. There was no operative mortality and no complications from the pneumoperitoneum. CONCLUSIONS We conclude that pneumoperitoneum after bilobectomy is safe and easy to do. It decreases the incidence of air leaks and of pneumothoraces and shortens hospital stay without increasing morbidity. We recommend pneumoperitoneum after bilobectomy at the time of thoracotomy, especially if there are residual small air leaks that cannot be sealed before chest closure.

Abstract
BACKGROUND Inflammatory pseudotumors of the lung are rare and often present a dilemma for the surgeon at time of operation. We reviewed our experience with patients who have this unusual pathology. METHODS Between February 1946 and September 1993, 56,400 general thoracic surgical procedures were performed at the Mayo Clinic. Twenty-three patients (0.04%) had resection of an inflammatory pseudotumor of the lung. There were 12 women and 11 men. Median age was 47 years (range, 5 to 77 years). Six patients (26%) were less than 18 years old. All pathologic specimens were re-reviewed, and the diagnosis of inflammatory pseudotumor was confirmed. Eighteen patients (78%) were symptomatic which included cough in 12, weight loss in 4, fever in 4, and fatigue in 4. Four patients had prior incomplete resections performed elsewhere and underwent re-resection because of growth of residual pseudotumor. Wedge excision was performed in 7 patients, lobectomy in 6, pneumonectomy in 6, chest wall resection in 2, segmentectomy in 1, and bilobectomy in 1. Complete resection was accomplished in 18 patients (78%). Median tumor size was 4.0 cm (range, 1 to 15 cm). There were no operative deaths. Follow-up was complete in all patients and ranged from 3 to 27 years (median, 9 years). RESULTS Overall 5-year survival was 91%. Nineteen patients are currently alive. Cause of death in the remaining 4 patients was unrelated to pseudotumor. The pseudotumor recurred in 3 of the 5 patients who had incomplete resection; 2 have had subsequent complete excision with no evidence of recurrence 8 and 9 years later. CONCLUSIONS We conclude that inflammatory pseudotumors of the lung are rare. They often occur in children, can grow to a large size, and are often locally invasive, requiring significant pulmonary resection. Complete resection, when possible, is safe and leads to excellent survival. Pseudotumors, which recur, should be re-resected.

Abstract
BACKGROUND Air leaks (ALs) are a common complication after pulmonary resection, yet there is no consensus on their management. METHODS An algorithm for the management of chest tubes (CT) and ALs was applied prospectively to 101 consecutive patients who underwent elective pulmonary resection. Air leaks were graded daily as forced expiratory only, expiratory only, inspiratory only, or continuous. All CTs were kept on 20 cm of suction until postoperative day 2 and were then converted to water seal. On postoperative day 3, if both a pneumothorax and AL were present, the CT was placed to 10 cm H2O of suction. If a pneumothorax was present without an AL, the CT was returned to 20 cm H2O of suction. Air leaks that persisted after postoperative day 7 were treated with talc slurry. RESULTS There were 101 patients (67 men); on postoperative day 1, 26 had ALs and all were expiratory only. Univariable analysis showed a low ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) (p = 0.005), increased age (p = 0.007), increased ratio of residual volume to total lung capacity (RV/TLC) (p = 0.04), increased RV (p = 0.02), and an increased functional residual capacity (FRC) (p = 0.02) to predict the presence of an AL on postoperative day 1. By postoperative day 2, 22 patients had expiratory ALs. After 12 hours of water seal, 13 of the 22 patients' ALs had stopped, and 3 more sealed by the morning of postoperative day 3. However, 2 of the 6 patients whose ALs continued experienced a pneumothorax. Five of the 6 patients with ALs on postoperative day 4 still had ALs on postoperative day 7, and all were treated by talc slurry through the CT. All ALs resolved within 24 hours after talc slurry. CONCLUSIONS Most ALs after pulmonary resection are expiratory only. A low FEV1/FVC ratio, increased age, increased RV/TLC ratio, increased RV, and an increased FRC were predictors of having an ALs on postoperative day 1. Conversion from suction to water seal is an effective way of sealing expiratory AL, and pneumothorax is rare. If an expiratory AL does not stop by postoperative day 4 it will probably persist until postoperative day 7, and talc slurry may be an effective treatment.

Abstract
OBJECTIVE To identify the possible cause(s) of hemolysis after mitral valve repair for mitral regurgitation (MR) and to evaluate the late outcome of surgical treatment. METHODS We reviewed all patients who had reoperation after valve repair for mitral regurgitation. Ten patients had reoperation because of hemolytic anaemia. The diagnosis of hemolysis was made by decreased serum haptoglobin, elevation of serum lactate dehydrogenase (LDH), and schistocytosis. No other causes of anaemia or hemolysis were identified in these six men and four women (ages 35-84 years; median 59 years). Interval between initial mitral valve repair and reoperation ranged from 40 to 165 days (median 87 days), and prior to reoperation, red cell transfusions (range 2-12 units; median 5 units) were required in all patients. Seven patients were symptomatic: two complained of easy fatigability and five were severely limited. Transesophageal echocardiogram during hemolytic evaluation showed only mild MR in two patients, moderate in five, moderately severe in two and severe in one. RESULTS Etiology of hemolysis was suggested from echocardiography and confirmed at reoperation. In one patient, an eccentric MR jet struck a pledget of a commissural annuloplasty. In the remaining nine patients, the regurgitant jet struck a non-endothelialized portion of the annuloplasty ring (Carpentier-Edwards n = 5; Duran n = 2; Cosgrove-Edwards n = 2). Seven patients had prosthetic replacement and three patients had re-repair. There were no operative deaths and all patients had resolution of hemolytic anaemia. CONCLUSIONS Relatively minor degrees of regurgitation after mitral valve repair can produce hemolytic anaemia which is manifested within the first few postoperative months. Most patients are highly symptomatic because of anaemia. The mechanism of red cell destruction is a high velocity eccentric stream of blood impacting on a small area of a prosthetic ring or pledget. This process retards endothelialization of the ring. Reoperation with re-repair or mitral valve replacement is safe and effectively relieves the hemolysis.

Abstract
Between July 1987 and May 1995, 11,315 patients underwent general thoracic surgical procedures at our institution. In 47 of these patients (0.42%), postoperative chylothorax developed. There were 32 men and 15 women with a median age of 65 years (range 21 to 88 years). Initial operation was for esophageal disease in 27 patients, pulmonary disease in 13, mediastinal mass in six, and thoracic aortic aneurysm in one. All patients were initially treated with hyperalimentation, cessation of oral intake, medium chain triglyceride diet, or a combination. Nonoperative therapy was successful in 13 cases (27.7%), and oral intake was resumed a median of 7 days later (range 2 to 15 days). Reoperation was required in the remaining 34 cases. The reoperation rate varied according to the type of initial operation. Twenty-four of the 27 patients (88.9%) who had undergone an esophageal operation required reoperation, versus only five of 13 patients (38.5%) who had undergone pulmonary resection (p < 0.001). Lymphangiography was performed in 16 patients and identified the site of the leak in 13. The thoracic duct was ligated in 32 of the 34 patients who required reoperation (94%). The remaining two patients were treated with mechanical pleurodesis and fibrin glue. Reoperation was successful in 31 of the 34 patients (91.2%). The single death among the 47 patients (2.1%) occurred in the reoperated group. Complications occurred in 18 patients (38.3%). Factors that predicted the need for reoperation were initial esophageal operation and average daily postoperative drainage greater than 1000 ml/day for 7 days. We conclude that postoperative chylothorax is an infrequent complication. Some cases can be managed without operation; however, we recommend early reoperation when drainage is greater than 1000 ml/day or if the chylous fistula occurs after an esophageal operation. The fistula can usually be controlled by ligation of the thoracic duct.

Abstract
BACKGROUND Some patients are denied curative pulmonary resection for lung carcinoma because of pulmonary insufficiency. To identify factors that affect postoperative morbidity and mortality, we reviewed 85 consecutive patients (53 men and 32 women) with a preoperative forced expiratory volume in 1 second of less than 1.2 L who underwent pulmonary resection for lung cancer between January 1986 and December 1990. METHODS Median age was 70 years (range, 49 to 82 years). Sixty patients (71%) had been previously denied operation because of pulmonary insufficiency. Preoperative pulmonary function demonstrated a median preoperative forced expiratory volume in 1 second of 1.0 L (44% of predicted normal; range, 0.5 to 1.2 L) and a diffusing capacity of the lung for carbon monoxide of 60% of predicted normal (range, 22% to 104%). RESULTS Pneumonectomy was done in 6 patients (7.1%), bilobectomy in 6 (7.1%), lobectomy in 38 (44.7%), segmentectomy in 12 (14.1%), and wedge excision in 29 (27.1%). The median predicted postoperative forced expiratory volume in 1 second was 0.83 L (34% of predicted normal; range, 0.45 to 1.14 L), and the median predicted postoperative diffusing capacity of the lung for carbon monoxide was 48% of predicted normal (range, 19% to 87%). Seventy-two patients (85%) received postoperative epidural analgesia. Median hospitalization was 15 days (range, 5 to 66 days). Operative mortality was 2.4%, and complications occurred in 49%. We did not identify any factors that predicted postoperative morbidity and mortality. Median follow-up was 3.2 years (range, 0.2 to 9 years). Seven patients (8%) required supplemental home oxygen. A predicted postoperative percent forced expiratory volume in 1 second less than 43% correlated with the need for home oxygen (p < 0.05). Overall 5-year survival was 44.0%. Survival for stage I cancer was 54.2%; stage II, 33.1%; and stage IIIa, 21.3%. CONCLUSIONS We conclude that some patients with lung cancer and compromised pulmonary function can safely undergo pulmonary resection if selected appropriately.

Abstract
To better understand late outcomes of mitral valve repair, we reviewed the cases of 49 consecutive patients who underwent reoperation between January 1974 and May 1992 for recurrent valve dysfunction after previous valvuloplasty for mitral regurgitation. There were 27 men (55%) and 22 women, with a median age of 63 years (range 20 to 84 years). Original procedures included annuloplasty and posterior leaflet repair in 15 patients (31%), annuloplasty and anterior leaflet repair in 15 (31%), commissural plication in 13 (27%), and complex bileaflet repairs in six (12%). Median time between initial mitral repair and reoperation was 2.4 years (range 2 months to 25.3 years). Indications for reoperation included recurrent severe mitral regurgitation in 34 patients (70%), hemolytic anemia from mitral regurgitation in seven (14%), mixed mitral regurgitation and stenosis in seven (14%), and isolated mitral stenosis in one (2%). Before reoperation, 36 patients were in New York Heart Association functional class III and 11 were in class IV. Initial repairs were intact at the second operation in 32 patients (65%), and the etiology of recurrent mitral regurgitation in these patients was fibrosis or calcification of the anulus or leaflets in 22 patients, newly ruptured chordae in seven, and perforated leaflets in three. The causes of mitral regurgitation in the 17 patients whose initial repair had failed included dehiscence of commissural repairs in nine patients, dehiscence of ring annuloplasty in four, and break-down of chordal or leaflet repair in four. Patients with original repairs involving the anterior leaflet had a significantly shorter time between operations (p = 0.006). In eight patients (16%), the mitral valve was repaired again; in the remaining 41 patients (84%), prosthetic replacement was performed. Operative mortality rate was 4% (two patients). All eight patients who underwent mitral valve rerepair had no mitral regurgitation, trivial regurgitation, or mild regurgitation at discharge from the hospital. Follow-up was 100% complete at a mean of 5.1 years (range 1 to 19 years). Forty-one patients (87% were in New York Heart Association functional class I or II, and survival at 5 years was 75.3%. Of the eight patients who underwent a second repair, seven had no regurgitation, trivial regurgitation, or mild regurgitation at a median of 4 years' follow-up. The low mortality associated with reoperation supports an aggressive approach toward mitral regurgitation with initial repair. A second repair can be performed in selected patients with durable results at 4 years.

Abstract
BACKGROUND Resection of a mainstem bronchus with pulmonary preservation is a therapeutic option when disease is limited to the mainstem bronchus. We reviewed our experience with this procedure to determine the operative morbidity, mortality, and long-term outcome. METHODS From January 1965 through January 1995, 22 patients (13 male, 9 female) underwent circumferential mainstem bronchial sleeve resection without removal of pulmonary parenchyma. Median age was 37 years (range, 12 to 70 years). The right mainstem bronchus was involved in 12 patients and the left, in 10. Nineteen patients (86%) were symptomatic; symptoms included cough in 5, dyspnea in 5, wheeze in 3, hemoptysis in 3, and a combination of these in 3. Conventional tomography was done in 8 patients and identified every lesion. Bronchoscopy was diagnostic in all patients. Resection was for cancer in 15 patients (68%), benign stricture in 5 (23%), and an impacted broncholith in 2 (9%). The cancer was a carcinoid in 9 patients, a mucoepidermoid carcinoma in 3, squamous cell carcinoma in 2, and adenoid cystic carcinoma in 1. Fourteen patients were postsurgically classified as stage IIIA (T3 NO MO) and 1 patient as stage IIIB (T4 N2 M0). The median length of the resected bronchus was 2.0 cm (range, 1.0 to 4.0 cm). Two patients required hilar release maneuvers. The bronchial anastomosis was reinforced with pleura in 10 patients, pericardium in 2, and serratus anterior muscle in 1. RESULTS There were no operative deaths. Three patients (14%) had postoperative complications. Follow-up was complete and ranged from 6 months to 25.7 years (median follow-up, 10.2 years). Twenty-one patients are currently alive. All patients are asymptomatic except 1 patient, who required a stent for an anastomotic stricture. No patient has had recurrence of cancer. CONCLUSIONS In properly selected patients, mainstem bronchial sleeve resection with lung preservation can be performed safely and provides excellent relief of symptoms with good long-term survival.

Abstract
Between May 1983 and March 1, 1995, 50 patients had replacement of an obstructed pulmonary ventricle-pulmonary artery conduit with an autologous tissue reconstruction in which a prosthetic roof was placed over the fibrous tissue bed of the explanted conduit. The roof was constructed with xenograft pericardium (most recently) (n = 42), homograft dura mater (n = 5), or Dacron fabric (n = 3). Patient ages ranged from 5 to 34 years (median 16 years). The explanted conduits were Hancock conduits (n = 33), Tascon conduits (n = 6), homograft (n = 4), Dacron tube (n = 3), and others (n = 4). Preoperative maximum systolic gradients ranged from 44 to 144 mm Hg (median 78 mm Hg). Thirty-seven concomitant cardiac procedures were done in 29 patients. When a valve was necessary (n = 15), it was possible to place a large-sized valve in the autologous tissue reconstructions (range 22 to 29 mm, median 26 mm). Cardiopulmonary bypass times ranged from 34 to 223 minutes (median 84 minutes), and aortic crossclamp times ranged from 0 (in 32 patients) to 109 minutes (median 0 minutes). Intraoperative postrepair peak systolic gradients from pulmonary ventricle to pulmonary artery ranged from 0 to 33 mm Hg (median 13 mm Hg). There was one early death (2%) in a patient who had additional cardiac procedures. Follow-up was complete in all patients and ranged from 1 month to 11.8 years (median 7.5 years). There were two sudden late deaths: conduits in both were known to be free from obstruction. Forty-four of the 47 surviving patients had evaluation of the gradient by echocardiography or cardiac catheterization 1 month to 11 years (median 7 years) after operation. The gradients ranged from 5 to 45 mm Hg (median 20 mm Hg). None of the conduits developed an obstructive peel, valve obstruction, or valve incompetence. At 10 years, the freedom from reoperation for conduit obstruction was 100%, and freedom from reoperation for any cause was 81%. This technique simplifies conduit replacement, allows for a generous-sized outflow tract, has a low risk, and yields late results that appear superior to those of cryopreserved homografts or other types of extracardiac conduits.

Abstract
OBJECTIVE To present our experience with mediastinal parathyroid cysts and summarize previously reported cases. DESIGN We retrospectively reviewed medical records and reviewed the pertinent literature. MATERIAL AND METHODS The clinical, operative, and pathologic findings in 7 cases of mediastinal parathyroid cysts encountered at one institution and 31 cases previously reported in the literature are described. RESULTS Rarely, cysts may arise from an aberrant mediastinal parathyroid gland. Such cysts may manifest as a symptomatic mass, as an asymptomatic finding on roentgenography, or during the assessment of a patient with hyperparathyroidism. The diagnosis may be made by fine-needle aspiration or by excision and pathologic examination. CONCLUSION Functioning parathyroid cysts represent degeneration of a hyperfunctioning gland, such as an adenoma, and are usually removed through a cervical approach. Nonfunctioning cysts in asymptomatic patients with normal serum calcium levels are considered indeterminate and should be managed accordingly. Excision is usually recommended.

Abstract
Between 1985 and 1993, 32 patients (24 male and 8 female) underwent colon interposition for replacement of the esophagus at the Mayo Clinic. Median age was 58.5 years (range, 1 to 79 years). The colon was used because of an inadequate stomach in 27 patients (84%) and as the conduit of choice in 5 (16%). Esophageal cancer was present in 15 patients (47%). The left colon was used in 20 patients (63%) and the right, in 12 (38%). The colon was placed substernally in 19 patients (59%) and in the esophageal bed in 13 (41%). The operative mortality was 9%; cause of death was ischemic necrosis of right colon conduits in 2 patients and adult respiratory distress syndrome in 1 patient. Major complications occurred in 4 additional patients and included ischemic colitis of a right colon conduit, Roux-en-Y limb obstruction, chylothorax, and an anastomotic leak. Follow-up was complete for all patients and ranged from 15 months to 7 years (median follow-up, 2.3 years). Eleven patients died during follow-up. The cause of death was metastatic esophageal cancer in 9 patients, myocardial infarction in 1 patient, and respiratory failure in 1 patient. At last follow-up, 26 of the 29 operative survivors had little or no difficulty eating. Two patients had dumping symptoms, and 1 patient had severe dysphagia. Seven patients required dilation of the esophagocolonic anastomosis. We conclude that colon interposition for esophageal replacement provides acceptable long-term function; however, early morbidity and mortality are considerable.

Abstract
Between 1965 and 1989, 96 consecutive patients (64 men and 32 women) underwent complete pulmonary resection for metastatic renal cell carcinoma. Median age was 63 years (range, 33 to 82 years). Median time between nephrectomy and pulmonary resection was 3.4 years (range, 0 to 18.4 years). Forty-eight patients had solitary metastasis, 16 had two, 18 had three, and 14 had more than three. Wedge excision was performed in 62 patients, segmentectomy in 3, lobectomy in 25, bilobectomy in 3, and pneumonectomy in 3. Fourteen patients had repeat thoracotomy for recurrent metastasis; 34 other patients also had complete resection of limited extrapulmonary disease. There were no operative deaths. Median follow-up was 3 years (range, 70 days to 19.0 years). Overall 5-year survival was 35.9%. Patients with solitary metastasis had a 5-year survival of 45.6% compared with 27.0% for patients with multiple metastases (p < 0.05). Patients with a tumor-free interval greater than the median of 3.4 years had a better survival (p = 0.05) than those with a tumor-free interval less than or equal to 3.4 years. Five-year survival for patients who underwent repeat thoracotomy or had complete resection of extrapulmonary disease did not differ from overall survival. We conclude that resection of renal lung metastasis is safe and effective, that patients with solitary metastasis have a better survival than those with multiple metastases, that resectable extrapulmonary disease does not necessarily contra-indicate pulmonary resection, and that repeat thoracotomy is warranted in selected patients with recurrent lung metastases.

Abstract
We undertook a multi-institutional, retrospective study of 51 patients with adrenal tumors (pheochromocytomas, functioning and nonfunctioning cortical adenomas, cysts and carcinomas). All patients had computed tomography (CT) with a maximum of 5 millimeter cuts the week before undergoing complete adrenalectomy. Pathologists were asked to measure the tumor to the nearest 0.1 centimeter. Tumor size obtained from pathologic reports (actual size) and CT reports (estimated size) were compared. Adrenal tumors were divided into two groups on the basis of size--tumors with actual size of 6 centimeters or greater and tumors with actual size of less than 6 centimeters. Statistical analysis was performed with Newman-Keuls analysis of variance. After controlling for tumor type and for the institution at which the measurement was made, we found that CT consistently underestimated adrenal tumor size in both tumor groups. Moreover, the average, underestimated difference for tumors 6 centimeters or greater was 32 percent, but 47 percent for tumors less than 6 centimeters (p = 0.060). CT seemed to underestimate the size of small adrenal tumors more than large tumors. Because the decision to operate on solid, nonfunctioning adrenal tumors is based on tumor size and because CT is currently the standard technique used to estimate size, our findings need to be considered before undertaking surgical treatment.
