Idiopathic laryngotracheal stenosis: effective definitive treatment with laryngotracheal resection.
OBJECTIVE: Little was known about idiopathic laryngotracheal stenosis when it was first described. We have operated on 73 patients with idiopathic laryngotracheal stenosis, have confirmed its mode of presentation and response to surgical therapy, and have established long-term follow-up. METHODS: Charts of 73 patients treated surgically for idiopathic laryngotracheal stenosis between 1971 and 2002 were retrospectively reviewed. RESULTS: All patients were treated with a single-staged laryngotracheal resection, with (36/73) and without (37/73) a posterior membranous tracheal wall flap. Nearly all were women (71/73), with a mean age of 46 years (range, 13-74 years). Twenty-eight (38%) of 73 had undergone a previous procedure with laser, dilation, tracheostomy, T-tube, or laryngotracheal operations. After laryngotracheal resection, the majority of patients (67/73) were extubated in the operating room, and 7 required temporary tracheostomies, only 1 of whom was among the last 30 patients. All were successfully decannulated. There was no perioperative mortality. Principal morbidity was alteration of voice quality, which was mild and tended to improve with time. Sixty-seven (91%) of 73 patients had good to excellent long-term results with voice and breathing quality and do not require further intervention for their idiopathic laryngotracheal stenosis. CONCLUSION: Idiopathic laryngotracheal stenosis is an entity that occurs almost exclusively in women and is without a known cause. It is not a progressive process, but the timing of the operation is crucial. Single-staged laryngotracheal resection is successful in restoring the airway while preserving voice quality in more than 90% of patients. Protective tracheostomy is now rarely required (1/30). Long-term follow-up shows a stable airway and improvement in voice quality.

Thymoma: current medical and surgical management.
Thymoma is a rare neoplasm usually with an indolent growth pattern; however, local invasion and/or dissemination may occur. Surgery has been the standard of care for early stage disease with good to excellent cure rates anticipated. This neoplasm has been found to be relatively sensitive to cisplatinum-based chemotherapy as compared with most other epithelial tumors. Aggressive multimodality therapy therefore can result in long-term disease-free survival for patients presenting with locally advanced or even disseminated disease. This chapter outlines the current medical and surgical treatment options for thymoma.

Complication of benign tracheobronchial strictures by self-expanding metal stents.
OBJECTIVES: Self-expanding metal stents are used to palliate benign strictures. We examined the complications of this approach. METHODS: Between 1997 and 2002, we observed recurrent airway obstruction and extension of benign inflammatory strictures after the placement of tracheobronchial Microvasive Ultraflex stents and Wallstents (Boston Scientific Corp, Natick, Mass), in 10 patients with postintubation strictures and 5 with other indications; all but 1 patient were referred to us. Patients with tracheal (9), subglottic (1), combined tracheal and subglottic (3), and bronchial (2) strictures had been treated with covered and uncovered Wallstents (6) and Microvasive Ultraflex stents (9). RESULTS: After stent insertion, stricture and granulations within previously normal airway were seen in all patients. New subglottic strictures resulting from the stent caused hoarseness in 4 patients. A bronchoesophageal fistula was found in 1 patient at presentation and a tracheoesophageal fistula in another during extraction of a Wallstent. Primary surgical reconstruction, judged to have been feasible before wire stent insertion in 10 patients, was possible after stenting in only 7 and failed in 2. Palliative tubes were placed in 60% (9/15). Self-expanding metal stents may lengthen luminal damage, incite subglottic strictures, and cause esophagorespiratory fistula in inflammatory airway strictures. The injury is severe, occurs after a short duration of stenting, and precludes definitive surgical treatment or requires more extensive tracheal resection. CONCLUSION: The current generation of self-expanding metal stents should be avoided in benign strictures of trachea and bronchi.

Minitracheostomy.
Minitracheostomy is a safe bedside procedure that is a useful adjunct to facilitate secretion clearance in patients with sputum retention. It can also be used in a prophylactic fashion after operations in high-risk patients. Insertion requires a trained physician and an assistant. Complications are rare and are usually avoidable.

Epidural abscess after epidural anesthesia and continuous epidural analgesia in a patient with gastric lymphoma.
A case of spinal epidural abscess, a rare but possibly devastating complication of epidural instrumentation and catheterization, is described in an immunocompromised patient, which presented atypically and which resulted in the patient's death.

Pediatric tracheal surgery.
Pediatric tracheal surgery is uncommon, and few centers have enough experience to make meaningful conclusions about treatment. Short-segment congenital tracheal stenosis is treated by tracheal resection, whereas long-segment stenosis is treated by either augmentation tracheoplasty or slide tracheoplasty (the author's preferred approach). Tracheomalacia is treated most commonly by aortopexy. Postintubation tracheal stenosis is usually treated by tracheal (or laryngotracheal) resection.

Tracheoinnominate fistula: diagnosis and management.
TIF is a rare and often fatal complication of tracheostomy. Bleeding from the trachea after tracheostomy demands urgent investigation. Bronchoscopy is the diagnostic procedure of choice. Bedside control of hemorrhage by cuff overinflation or by digital arterial compression can be lifesaving. Prompt operation with division of the innominate artery and subsequent separation of the trachea from the divided artery by viable tissue is indicated. Neurologic complications are rare.

Tracheomalacia.
Tracheomalacia is a rare tracheal problem that leads to collapse of the airway and expiratory flow obstruction. Expiratory CT scans are the diagnostic test of choice in adults. Chronic obstructive pulmonary disease is the most common cause of adult tracheomalacia. Plication of the membranous wall to polypropylene mesh to recreate the normal airway shape (membranous wall tracheoplasty) is an effective treatment in adults.

Omentum is highly effective in the management of complex cardiothoracic surgical problems.
OBJECTIVES: Vascularized, pedicled tissue flaps are often used for cardiothoracic surgical problems complicated by factors that adversely affect healing, such as previous irradiation, established infection, or steroid use. We reviewed our experience with use of the omentum in these situations to provide a yardstick against which results with other vascularized flaps (specifically muscle flaps) could be compared. METHODS: A retrospective review was undertaken of 85 consecutive patients in whom omentum was used in the chest. In 47 patients (group I), use of omentum was prophylactic to aid in the healing of closures or anastomoses considered to be at high risk for failure. In 32 patients (group II), omentum was used in the treatment of problems complicated by established infection. In 6 patients (group III), omentum was used for coverage of prosthetic chest wall replacements after extensive chest wall resection. RESULTS: Overall, omental transposition was successful in its prophylactic or therapeutic purpose in 88% of these difficult cases (75/85). Success with omentum was achieved for 89% of patients (42/47) in group I, 91% of patients (29/32) in group II, and 67% of patients (4/6) in group III. Three patients (3.5%) had complications of omental mobilization. Four patients (4.7%) died after the operation as a result of failure of the omentum to manage the problem for which it was used. CONCLUSIONS: Results with omental transposition compare favorably with published series of similarly challenging cases managed with muscle transposition. Complications of omental mobilization are rare. We believe that its unique properties render the omentum an excellent choice of vascularized pedicle in the management of the most complex cardiothoracic surgical problems.

Successful treatment of idiopathic laryngotracheal stenosis by resection and primary anastomosis.
We studied the early and long-term response of idiopathic laryngotracheal stenosis (ILTS) to treatment by 1-stage laryngotracheal or tracheal resection and reconstruction in 73 patients. Nineteen of the 72 (26%) noted no difference in their voices or any difficulty in breathing after reconstruction. Forty-seven (64%) described loss of ability to project their voices as loudly as before or noted some difficulty in singing as well as they did before. Five (7%) had various degrees of dyspnea or stridor on effort. One needed continued dilation. The median follow-up was 8 years. Surgical treatment gave good or excellent results in 90% of these patients with ILTS. Recurrence or progression of stenosis was not evident.

Benign broncho-esophageal fistula in the adult.
BACKGROUND: Benign broncho-esophageal fistula (BEF) in the adult is rare, and occurs as a complication of inflammatory disorders, foreign body ingestion, or congenital anomalies. Nonspecific symptoms lead to a delay in diagnosis. METHODS: The charts of 13 patients from 1960 to 2001 at the Massachusetts General Hospital were retrospectively reviewed. RESULTS: Nine patients had chronic cough, which worsened upon ingestion. Four patients developed BEF after prior thoracic surgery, and 3 after histoplasmosis. Silicosis, foreign body ingestion, lye ingestion, bronchogenic cyst, esophageal diverticulum, and a congenital anomaly caused BEF in 1 patient each. Barium swallow was the most useful diagnostic test. Fistulas most often arose from the right bronchial tree and communicated with the distal esophagus. Management involved excision of the tract, primary closure of the bronchus and esophagus, and interposition of vascularized tissue. There was one perioperative failure, but no long-term recurrences after successful surgical closure. CONCLUSIONS: The majority of benign BEF in adults are acquired, and result from mediastinal inflammation. Accurate recognition and surgical closure prevents persistent uncontrolled aspiration and pulmonary sepsis.

Induction chemoradiation compared with induction radiation for lung cancer involving the superior sulcus.
BACKGROUND: The usual approach of induction radiation therapy (RT) followed by resection of superior sulcus tumors results in many incomplete resections, a high local recurrence rate, and suboptimal survival. Induction chemoradiotherapy (CT/RT) has been shown to reduce local and distant recurrences and improve survival in stage III lung cancer. We investigated the role of induction CT/RT in superior sulcus patients. METHODS: This was a single-institution, retrospective study. RESULTS: From 1985 to 2000, 35 consecutive patients underwent induction treatment followed by resection of a superior sulcus tumor. All patients had mediastinoscopy first to exclude N2 disease, and all were N0 at final pathologic examination. Twenty patients had induction RT (mean, 39 Gy), and 15 had induction CT/RT (mean, 51 Gy) with concurrent cisplatin-based chemotherapy. There was no treatment mortality. Complete resection was performed in 16 of 20 (80%) of the RT patients and in 14 of 15 (93%) of the CT/RT patients (p = 0.15). The pathologic response from the induction treatment was complete or near complete in 7 of 20 (35%) of the RT patients and in 13 of 15 (87%) of the CT/RT patients (p = 0.001). The median follow-up was 167 months in the RT patients and 51 months in the CT/RT patients. Two-year and 4-year survival was 49% and 49% (95% confidence interval, 26% to 71%) in the RT patients and 93% and 84% (95% confidence interval, 63% to 100%) in the CT/RT patients, respectively (p = 0.01). The local recurrence rate was 6 of 20 (30%) in the RT patients and 0 in the CT/RT patients (p = 0.02). CONCLUSIONS: Induction CT/RT for superior sulcus tumors appears to offer improved survival compared with induction RT alone.

Pediatric tracheal surgery.
BACKGROUND: Pediatric tracheal procedures are uncommon. We reviewed our experience to clarify management and results. METHODS: Retrospective single-institution review of pediatric tracheal operations, 1978 to 2001. RESULTS: One hundred sixteen children were evaluated, mean age 10.4 years (10 days to 18 years). Tracheal pathology was postintubation stenosis (n = 72; 62%), congenital stenosis (n = 23; 20%), neoplasm (n = 8; 7%), tracheomalacia (n = 7; 6%), and trauma (n = 6; 5%). Twenty-nine patients had previous tracheal operations. Thirty-six patients received only a minor procedure. Eighty patients had major operations: tracheal resection (n = 46; 58%), laryngotracheal resection (n = 22; 28%), slide tracheoplasty (n = 7; 9%), and carinal resection (n = 5; 6%). The mean length of airway resected was 3.3 cm (1.5 to 6 cm), which represented 30% of the entire trachea. Twenty-eight patients (35%) had complications. These included tracheomalacia (n = 3), recurrent nerve injury (n = 3), laryngeal edema requiring intubation (n = 2), stroke (n = 1), esophageal leak (n = 1), and lobar collapse (n = 1). Nineteen patients had anastomotic failure: severe restenosis (n = 6), mild restenosis (n = 9), dehiscence (n = 2), dehiscence with tracheoesophageal fistula (n = 1), and tracheoinnominate fistula (n = 1). Two children died (2.5%). Complications were more frequent in children less than 7 years of age (p = 0.05) and after previous operations (p = 0.02). Longer fractions of tracheal resection (> 30%) were more likely to result in anastomotic failure (p = 0.0005). Sixty-four (80%) patients achieved a stable airway free of any airway appliance. All patients with neoplasms are alive. CONCLUSIONS: The principles of adult tracheal operations are directly applicable to children and usually lead to a stable, satisfactory airway. Children tolerate anastomotic tension less well than adults; resections more than 30% have a substantial failure rate.

Adjuvant radiation therapy for stage II thymoma.
BACKGROUND: Thymoma is difficult to study because of its indolent natural history. The criteria for administration of adjuvant radiation therapy remain controversial, and it is unclear whether patients with Masaoka stage II thymoma benefit from adjuvant radiation. The goal of this report was to determine whether or not this group benefits from radiation therapy in terms of disease-specific survival and tumor recurrence. METHODS: Case records of the Massachusetts General Hospital were retrospectively reviewed from 1972 to 1999. One hundred fifty-five patients underwent resection for thymoma, of which, 49 had stage II disease. The world literature was reviewed using a Medline search (1966 to 2001), and a secondary review of referenced works was performed. RESULTS: Fourteen stage II patients underwent radiation therapy. Thirty-five did not receive radiation therapy. Baseline prognostic factors between radiated and nonradiated groups were similar. All patients underwent complete resection. The addition of adjuvant radiotherapy did not significantly alter local or distant recurrence rates in stage II thymoma. Disease-specific survival at 10 years in stage II patients was 100% with radiotherapy and without radiotherapy (p = 0.87). There was one recurrence in the nonradiated group at 180 months, which was outside the usual radiation portal. CONCLUSIONS: Most stage II patients do not require adjuvant radiation therapy and can be observed after complete resection.

Surgical techniques and outcomes for primary nonseminomatous germ cell tumors.
Patients with primary mediastinal nonseminomatous germ cell tumors are usually young men with large anterior mediastinal masses. The diagnosis can usually be established with measurement of serum tumor markers and a fine-needle aspiration biopsy. The mainstay of treatment is cisplatin-based chemotherapy. Resection of the residual postchemotherapy mass is usually necessary and is performed even with persistently elevated tumor markers if a clean resection is possible. The finding of necrotic tumor predicts long-term survival, whereas persistent germ cell cancer has a less favorable prognosis.

Management of congenital tracheal stenosis by means of slide tracheoplasty or resection and reconstruction, with long-term follow-up of growth after slide tracheoplasty.
OBJECTIVE: The difficult problem of congenital tracheal stenosis is infrequent and has been managed with several methods. Patch tracheoplasty has been favored in recent years. Alternative experience with a simpler program of slide tracheoplasty for long-segment stenosis or resection and reconstruction for short-segment stenosis is described and proposed as preferable. Long-term growth after slide tracheoplasty was studied. METHODS: Eleven consecutive patients aged 10 days to 23 years with varied patterns of stenosis (including concurrent pulmonary artery sling, anomalous right upper lobe bronchus, and bridge bronchus) had their stenoses corrected, 8 by means of slide tracheoplasty and 3 by means of resection and anastomosis. Retrospective review was made of hospital course, complications, and long-term results, with observation of growth in 4 patients (from more than 1(1/2)-7(3/4) years). RESULTS: All patients are alive and enjoy good airways. Only 3 patients who needed concomitant cardiovascular procedures and 1 with poor ventricular function required bypass. Eight were extubated immediately or on the day of the operation, 1 at 3 days, and 1 at 8 days. A patient with complex anomalies needed 10 days of ventilation. Three had anastomotic granulomas successfully treated by means of a single bronchoscopy. Long-term airway growth was entirely satisfactory after slide tracheoplasty in 4 infants and small children (aged 10 days, 3 months, 6 months, and 3(1/2) years, respectively). CONCLUSIONS: Slide tracheoplasty gives excellent short- and long-term results because long congenital stenosis is reconstructed with native tracheal tissue and is therefore immediately stable and lined with normal epithelium, and the operation is accomplished more simply and with a generally more benign postoperative course. Wholly satisfactory growth of the repaired segment occurs. Less common short congenital stenosis is effectively managed with resection and anastomosis.
