Repair of large, iatrogenic, tracheo-esophageal fistulae

Supraglottic jet oxygenation and ventilation via nasopharyngeal airway for a patient with iatrogenic tracheoesophageal fistula: A case report

Background

Iatrogenic tracheoesophageal fistula (TEF) is a rare but life-threatening condition. No consensus has been reached regarding TEF treatment, though, stenting has been gaining popularity for less invasiveness than thoracic surgery. The airway management during stent placement for TEF could be challenging.

Case presentations

We report a patient who suffered from TEF after cardiac surgery with symptoms of persistent coughing and aspiration. He who was admitted for stent placement but ended up in failure and referred to our institution for further treatment. We successfully took advantage of the supraglottic jet oxygenation and ventilation (SJOV) during stent placement.

Conclusion

This is the first case so far describing SJOV in complicated stenting treatment. This demonstrates that SJOV can be applied for stent placement in TEF patients with restricted airways.

Surgical repair of mechanical ventilation induced tracheoesophageal fistula

PURPOSE

To evaluate the outcomes of surgery to repair tracheoesophageal fistula (TEF) caused by mechanical ventilation.

METHOD

Case series and review of all cases reported in English literature. Only reports of TEF following mechanical ventilation and containing description of surgical repair and outcomes were included.

RESULTS

A total of 41 studies comprising 143 patients met the inclusion criteria. Most studies had incomplete information on important variables such as co-morbidity and fistula size. Tracheal resection anastomosis (TRA) was the most common approach, performed in 91 (63.6%) patients (including three newly reported here). Lateral approach repair (LA) was done in 45 (31.5%) patients. The former had a higher incidence of pre-existing tracheal stenosis [53 (89.8%) vs. 7 (35%) cases; p < 0.001]. Flap interposition to augment the repair was done in 49 (53.9%) and 40 (88.9%) cases, respectively (p < 0.001). Successful and durable healing of the fistula were achieved in 90 (98.9%) cases in TRA and 39 (88.6%) cases in LA.

CONCLUSION

In carefully selected cases of TEF caused by mechanical ventilation, TRA is the most preferred approach, delivering successful healing in almost all cases. Where TRA is not indicated or preferred, LA appears to be a good alternative. Future studies should explicitly report all of the known co-variables, so that the exact indications for choosing a particular surgical approach could be better elucidated.

Outcome and safety of tailored surgical treatments of nonmalignant esophagotracheobronchial fistula: report of fourteen patients

Introduction

Acquired benign esophageal tracheobronchial fistulae are clinically rare. In this paper, we summarize our experiences in surgical treatment of 14 consecutive patients with acquired benign esophageal tracheobronchial fistula.

Methods

This series included patients who underwent surgery between January 2002 and June 2015 at our institution. We retrieved and analyzed data on demographics, operative characteristics, and surgical outcome of the patients.

Results

Bronchofiberscopy revealed the membranous trachea openings of fistulae and gastroendoscopy further showed lesions in the anterolateral wall of the esophagus. Thoracotomy, division of the fistulous tract, and closure of the esophagus and trachea and other procedures were performed. All operations were uneventful, and there was no perioperative and postoperative complication or death. Symptoms disappeared after surgery in patients. The median length of hospital stay was 53 (range 31–270) days. The patients were followed up for a median of 33.5 (range 15–168) months. No recurrence was reported.

Conclusion

Our results suggest that acquired benign esophageal tracheobronchial fistulae have a broad spectrum of anatomic pathologies and exhibit markedly varied clinical manifestations, and a surgical approach tailored to the condition of individual patients is recommended.

Iatrogenic esophago-tracheal fistula: Challenges in diagnosis and management

Esophageo-tracheal fistula is a rare condition, and in most cases such fistulas are caused by malignant disease or emergency endotracheal intubation. A case where a wrapped tablet produced a fistula between the esophagus and trachea is described. The patient is a male born in 1938 who swallowed a tablet without unwrapping it. The patient was treated with self-expanding metal stents (SEMS), but closure of the fistula was not achieved. Different examinations and treatment options are discussed. Surgical treatment for this condition has demonstrated considerable mortality and morbidity. In some cases closure of the fistula can be achieved by use of SEMS. Although we advise treatment of such cases with SEMS, in some cases treatment with stents will prove troublesome and the risk/benefit analysis will have to be reevaluated.

Post-intubation tracheoesophageal fistula with posterior glottic web

Tracheoesophageal fistula (TEF) after prolonged intubation could present as chronic aspiration and could be mistaken as unilateral or bilateral vocal fold palsy, especially when there was combined posterior glottic synechia. We present a case of post-intubation TEF which was successfully treated with tracheal resection and anastomosis with primary esophageal closure. The accompanying posterior glottic web was treated by endoscopic technique of web lysis, with topical application of mitomycin C solution.

Successful tubes treatment of esophageal fistula

AIM

To discuss the merits of "tubes treatment" for esophageal fistula (EF).

METHODS

A 66-year-old female who suffered from a bronchoesophageal and esophagothoratic fistula underwent a successful "three tubes treatment" (close chest drainage, negative pressure suction at the leak, and nasojejunal feeding tube), combination of antibiotics, antacid drugs and nutritional support. Another 55-year-old male patient developed an esophagopleural fistula (EPF) after esophageal carcinoma operation. He too was treated conservatively with the three tubes strategy as mentioned above towards a favorable outcome.

RESULTS

The two patients recovered with the tubes treatment, felt well and became able to eat and drink, presenting no complaint.

CONCLUSION

Tubes treatment is an effective basic way for EF. It may be an alternative treatment option.
