Comparative study of different treatments for malignant tracheoesophageal/bronchoesophageal fistulae

The aim of this study is to compare the survival time and quality of life (QOL) of patients who have received different treatment for tracheoesophageal/bronchoesophageal fistula. Between January 2003 and December 2007, 35 patients with malignant tracheoesophageal/bronchoesophageal fistula were recorded as the control group, gastrostomy group, and stenting group, respectively, according to the treatments they chose. Two weeks after the treatment, European Organization for Research and Treatment of Cancer Quality of Life Core 30 Questionnaire (QLQ-C30), Quality of Life Questionnaire-esophageal module (QLQ-OES18), and a respiratory symptom-related QOL index are employed to assess QOL of these patients. There is no significant difference in survival time and constituent ratio of death reason among groups. Except for eight patients who died within 2 weeks after the treatment, all other 27 patients returned back the questionnaires. As compared to the control group, patients in the gastrostomy group gained a low score in emotional function and financial situation, while patients in the stenting group had lower scores in financial problems and seven respiratory and eating-related symptoms. In contrast with the gastrostomy group, patients in stenting group had higher scores in emotional and social functions, and lower scores in six respiratory and eating-related symptoms. With patients' QOL considered, the self-expandable coated stenting should be the first choice of therapy for malignant tracheoesophageal/bronchoesophageal fistula, whereas gastrostomy should be kept from use.

[Atypical laryngo-tracheal post-intubation complications: three case reports]

Endotracheal intubation can induce iatrogenic laryngeal and tracheal complications, particularly when the intubation lasts for a long time. The ENT pratician's job is not only to cure the laryngeal sequelaes but also to prevent and diagnose them. Authors report three atypical cases of laryngeal and tracheal post-intubation complications (laryngeal bilateral immobility, interarythenoidal synechia, oesotracheal fistulae) and discuss them regarding medical literature data.

Acquired tracheo-oesophageal fistula: a case report

This is a case report of a girl aged 4 years who presented with repeated attacks of chocking and dysphagia. She was diagnosed to be having an acquired tracheo- oesophageal fistula caused by fish bone impaction. She was treated successfully. In this report, the literature was reviewed of this rare condition.

[Tracheoesophageal fistulas in anesthetic and intensive care practice]

The paper analyzes the etiology and pathogenesis of respiratory organ fistulas and their prevention and various treatment options (radical and palliative surgery and medical therapy). Particular attention is given to tracheoesophageal fistulas that are iatrogenic complications in anesthetic and intensive cares. The experience in treating the patients at the Department of Thoracic Surgery, Russian Research Center of Surgery, Russian Academy of Medical Sciences, before 1991 and from 1992 to 2007 is analyzed. Today's approach to the etiology and therapy for this severe iatrogenic complication is determined by the development of measures to prevent this complication and by the change in treatment policy in favor of early radical surgical interventions.

An approach to complex tracheostomal complications

Fistula formation following laryngectomy, most commonly pharyngocutaneous, is the most feared non-fatal complication with an incidence range from 5 to 30%. Tracheoesophageal fistulae are rare and are, most often, associated with the creation of a surgical speech fistula or the stomal recurrence of a malignant tumour. We present five cases of complex post-laryngectomy fistulae and a new approach to management. We advocate debridement of infected or necrotic tissue, primary suture of the oesophageal and tracheal defects with interposition of healthy viable tissue as a free transfer. If necessary, the trachea can be mobilised and the tracheostome is lowered to healthy tissue outside the radiotherapy field, with excision of the manubrium and hemi-clavicles. This technique allows reconstruction as a single stage procedure and does not preclude the future creation of a further tracheoesophageal fistula for voice rehabilitation.

[Aorto-oesophageal fistula in patient with Montgomery salivary bypass tube]

Aorto-oesophageal fistula is a well-reported pathology with several known causes. The co-existence of this pathology associated with the use of a Montgomery salivary bypass tube (MSBT) is exceptional and only one case is described in the literature. We present here a case report about an 81-year-old patient with an MSBT who died because of a massive upper gastrointestinal bleeding caused by an aorto-oesophageal fistula at the site of the MSBT. The literature on this pathology will also be reviewed.

Esophageal stents for malignant strictures close to the upper esophageal sphincter

BACKGROUND

Self-expanding stents are a well-accepted palliative treatment modality for strictures resulting from esophageal carcinoma. However, the use of stents close to the upper esophageal sphincter (UES) is considered to be limited by patient intolerance caused by pain and globus sensation and an increased risk of complications, particularly tracheoesophageal fistula formation and aspiration pneumonia.

OBJECTIVE

Our purpose was to determine the efficacy and safety of stent placement in patients with a malignant obstruction close to the UES.

DESIGN

Evaluation of 104 patients with dysphagia from a malignant stricture close to the UES treated in the period 1996-2006.

SETTING

Single university center.

PATIENTS

Patients with primary esophageal carcinoma (n = 66) or recurrent cancer after gastric tube interposition (n = 38) within 8 cm distance distal of the UES. Twenty-four (23%) patients also had a tracheoesophageal fistula.

INTERVENTIONS

Stent placement.

MAIN OUTCOME MEASUREMENTS

Functional and technical outcome, survival, complications, and recurrent dysphagia. Analyses were performed by chi(2) test, Kaplan-Meier curves, and log-rank testing.

RESULTS

Mean distance from the UES to the upper tumor margin was 4.9 +/- 2.6 cm and to the upper stent margin 3.1 +/- 2.3 cm. The procedure was technically successful in 100 of 104 (96%) patients. Fistula sealing was achieved in 19 of 24 (79%) patients. After 4 weeks, dysphagia had improved from a median score of 3 (liquids only) to 1 (some difficulties with solids). Total complications were seen in 34 of 104 (33%) patients. Of these, major complications (aspiration pneumonia [9], hemorrhage [8], fistula [7], and perforation [2]) occurred in 22 (21%) patients, whereas pain after stent placement was observed in 16 (15%) patients. Recurrent dysphagia occurred in 29 (28%) patients and was mainly caused by tissue ingrowth or overgrowth (n = 10), food bolus obstruction (n = 7), stent migration (n = 3), or other reasons (n = 11), such as persistent fistula (n = 5), difficulty with swallowing (n = 4), and dislocation of the stent (n = 2). Eight (8%) patients complained of globus sensation; however, in none of the patients was stent removal indicated.

LIMITATIONS

Retrospective design.

CONCLUSIONS

Stent placement is safe and effective for the palliation of dysphagia and sealing of fistulas in patients with a malignant stricture close to the UES. On the basis of these results, stent placement may be considered for palliation in this group of patients with an otherwise dismal prognosis.

Classification and Management of Tracheoesophageal and Tracheopharyngeal Fistulas After Laryngectomy

OBJECTIVES

Tracheoesophageal fistulas (TEF) and tracheopharyngeal fistulas (TPF) are intentionally created for prosthetic or surgical voice restoration after laryngectomy or can develop after radiotherapy or surgical interventions. If the fistula does not shrink or close spontaneously or does not respond to conservative measures, surgical closure of the fistula is indicated.

STUDY DESIGN

Retrospective study of 177 patients.

METHODS

Data of 168 laryngectomy patients who needed a voice prosthesis (VP) replacement were obtained. Our experiences with nine severe TEF/TPF were analyzed, and a classification of these fistulas depending on the anatomic and clinical appearance was developed.

RESULTS

TEF/TPF can be divided into five types: high TEF with leakage through the VP (type Ia), high TEF with leakage around the VP (type Ib), enlarged high TEF (type II), deep TEF (type III), TPF (type IV), and TPF associated with pharynx stenosis (type V). Persisting TEF/TPF after unsuccessful attempts at surgical closure in four patients and the surgical solutions and procedures in these rare cases are discussed in detail.

CONCLUSIONS

Leakage of TEF in prosthetic voice restoration usually responds well to conservative measures. If these measures fail, and in all cases of TPF, surgical intervention is necessary for transtracheostomal or transcervical closure with multilayer sutures of the esophagus and trachea. Persisting TEF/TPF after unsuccessful surgical attempts at revision surgery remain challenging. Our experiences show that tracheostoma transposition for dissociation of the cranial end of the trachea and the hypopharynx and esophagus is essential for effective closure. In rare cases of TPF combined with pharyngoesophageal stricture formation, a resection and immediate reconstruction of the stenotic pharyngoesophageal segment with a tube-shaped fasciocutaneous radial forearm flap must be considered.

Tracheal rupture in burns--a retrospective study

INTRODUCTION

Tracheal ruptures and tracheoesophageal injuries are rare, but life-threatening complications can arise during ventilation.

METHOD

A retrospective study of all burned patients placed on a ventilator between 2000 and 2005 (n=1693) identified two patients (0.1%) with a tracheal rupture and tracheoesophageal fistula (TOF). The diagnoses were confirmed using endoscopy and computed tomography. The tracheal and oesophageal defects were treated surgically immediately after diagnosis using a collar approach.

RESULTS

In all cases, withdrawal of ventilation proceeded without problems. Depending on their underlying condition, patients were transferred to normal wards with adequate spontaneous breathing and oral feeding.

CONCLUSION

Tracheal rupture and tracheoesophageal injury following orotracheal intubation is a rare complication in patients with burns (0.1% incidence). Following diagnosis, immediate surgical intervention is effective without further complications.

Tracheoesophageal fistula and tracheo-subclavian artery fistula after tracheostomy

Tracheoesophageal fistula and tracheo-arterial fistula are both uncommon but life-threatening complications after a tracheostomy. The most common source of a major hemorrhage is from the tracheo-innominate artery fistula. Most tracheo-arterial fistulas occur within the first 3 weeks after tracheostomy. We describe a very rare case of a patient who developed both a tracheoesophageal fistula and massive hemorrhage from a tracheo-left subclavian artery fistula 4 months after a tracheostomy procedure.

Aortopexy in Infants and Children—Long-term Follow-up in Twenty Patients

BACKGROUND

Aortopexy has become an established surgical procedure for the treatment of tracheomalacia (TM) in infants and children. The aim of the present study was to evaluate the clinical outcome and respiratory function after aortopexy in the long term.

METHODS

Between 1992 and 2006, 20 patients (6 female, 14 male) with TM were treated by bronchoscopically monitored pexis of the aorta via a right anterior thoracotomy. Patient age ranged from 4 months to 11 years (mean: 29 months). Five infants had previous surgery of esophageal atresia or tracheo-esophageal fistulae, and five other patients were operated on for gastroesophageal reflux. Postoperative tidal expiratory flow (TEF25%) was compared to age-related values.

RESULTS

Mean follow-up was 7.8 years (range: 13 months to 10.7 years). There was no early or late mortality. Most patients (n = 16) showed immediate and permanent relief of symptoms. Compared to corresponding age groups, median TEF25% was slightly but not significantly decreased after aortopexy (p = 0.15). In one patient a re-aortopexy was necessary. Another patient experienced recurrent tracheo-esophageal fistula 3 years after aortopexy.

CONCLUSIONS

The bronchoscopically guided aortopexy is an efficient and simple method in the surgical treatment of TM in infants and children. The follow-up data in this series of 20 patients showed improvement of respiratory function and permanent relief of symptoms in the long term.

Tracheoesophageal fistula managed with tracheal stent through flexible bronchoscopy without fluoroscopy

Inoperable malignant tracheoesophageal fistula (TEF) is characterised by an extremely poor prognosis. Tracheal or double (tracheal-esophageal) stenting through rigid bronchoscopy has been suggested as a valuable therapeutic option. We report on a patient with a large TEF successfully sealed by deployment of a self-expandable stent through flexible bronchoscopy (FB) without fluoroscopy. Dramatically improved health status permitted him to undergo radiation, attaining further clinical improvement. Four months after stent placement no sequelae were observed. During the fifth month a new fistula developed distally to the stent finally leading to death from septic complication. Palliative management of inoperable malignant TEF by tracheal stent placement through FB without fluoroscopy, is feasible, safe and rewarding leading to important clinical improvement.

Review of tracheo-esophageal fistula associated with endotracheal intubation

Tracheo-esophageal fistula (TEF) formation is a rare complication of either endotracheal intubation or tracheostomy. This complication is generally thought to be iatrogenic and occurs in less than 1% of patients. High-volume, low-pressure cuffs have made TEFs an infrequent occurrence; however, it still poses as a potential life-threatening condition. Evaluation and close monitoring of endotracheal tube (ETT) cuff pressures is an area of significance commonly overlooked and/or underemphasized by surgical residents. To illustrate and review this clinical problem, a case of an iatrogenic TEF as a consequence of excessive endotracheal cuff pressures is reported.

Tracheoesophageal fistula secondary to disk battery ingestion: a case report of gastric interposition and tracheal patch

The authors report a child with tracheoesophageal fistula secondary to disk battery ingestion. With respiratory compromise precluding expectant therapy and primary repair not achievable, gastric interposition and tracheal patch repair were undertaken in the acute phase. To the authors' knowledge, this is the first report of primary gastric interposition for traumatic tracheoesophageal fistula and suggest that immediate reconstruction can give an outcome at least as good as other reported approaches.

Esophageal bypass using a gastric tube and a cardiostomy for malignant esophagorespiratory fistula

Esophageal bypass with a gastric tube and a cardiostomy is a method recently devised for malignant esophagorespiratory fistula. This method separates completely the alimentary and respiratory tracts. Four patients underwent these procedures. No operative deaths occurred, nor was there any anastomotic leakage or disruption of the excluded esophagus. The average survival time was 7 months. However, all patients were allowed to consume food orally up to the last moment of life. This bypass procedure is simple and safe to perform, and is thus a feasible treatment choice for patients with such fistulas.

Nasogastric tube knotting with tracheoesophageal fistula - a rare association

The nasogastric tube is used extensively in medical practice. However, this innocent-looking tube can at times cause unexpected complications especially in patients with preexisting risk factors. A 25-year-old male was referred to our hospital with a blocked and impacted nasogastric tube which had been inserted to maintain his nutritional status after he sustained a caustic injury to the esophagus in an attempted suicide. Esophagoscopy was done, the knotted nasogastric tube was retrieved and a tracheoesophageal fistula was detected at the site of impacted knot. However, the patient succumbed to ARDS and sepsis before definitive surgery could be done. Nasogastric intubation is not a simple procedure as is the general concept and it should not be done in cases of caustic injury to the esophagus because of increased risk of complications in the face of preexisting inflammation. To our knowledge, this is the first case report of its kind in the literature review.

Esophageal stent placement for the palliation of dysphagia in lung cancer

BACKGROUND

The aim of this study was to evaluate the experience with expandable metal stents for the palliation of malignant dysphagia caused by lung cancer.

METHODS

Between August 2002 and April 2006, we deployed esophageal metal stents in 14 patients with esophageal involvement from lung cancer. The mean age of the patients was 61.4 years, and 12 were male patients. Expandable metal stents were inserted under fluoroscopic control over a guide-wire with the patient under conscious sedation.

RESULTS

Four patients had concomitant tracheoesophageal fistula. Eleven patients had received previous chemotherapy or radiotherapy and two had had a pneumonectomy. Immediate improvement after esophageal stent replacement was seen in all patients. The fistula was sealed off in all. All the patients remained asymptomatic during follow-up. All patients died, with mean survival of 10 weeks for patients with fistula and 8.3 months in the patients without fistula.

CONCLUSION

The poor quality of life associated with malignant dysphagia and tracheoesophageal fistula in lung cancer patients can be significantly improved by a non-surgical intervention such as the deployment of expandable metal stents.

GASTRIC ANTRAL PATCH OESOPHAGOPLASTY FOR IATROGENIC TRACHEO-OESOPHAGEAL FISTULA

Acquired tracheo-oesophageal fistula is a devastating condition, usually occurring as a late manifestation of oesophageal or other thoracic malignancies. In these cases palliation by placement of an oesophageal stent is the preferred option, but management of a large non-malignant fistula is more complex. In many patients in whom primary repair of the defects is not possible oesophagectomy may be seen as the best treatment. We present a case of a large tracheo-oesophageal fistula repaired with a gastric antral patch oesophagoplasty and intercostal muscle flap.

Repair of large, iatrogenic, tracheo-esophageal fistulae

Closure of large, iatrogenic, tracheo-esophageal fistulae present a formidable technical challenge. Our method of repair is presented, which describes the exposure and subsequent closure that relies on creating a new "membranous" trachea using remnant flaps of the esophageal wall of the fistula.

Esophagotracheal fistula caused by gastroesophageal reflux 9 years after esophagectomy

Fistula between digestive tract and airway is one of the complications after esophagectomy with lymph node dissection. A case of esophagotracheal fistula secondary to esophagitis 9 years after esophagectomy and gastric pull-up for treatment of esophageal carcinoma is described. It was successfully treated with transposition of a pedicled pectoralis major muscle flap.
