Recurrent, Nonmalignant Tracheoesophageal Fistulas and the Need for Surgical Improvisation

Surgical strategies for benign acquired tracheoesophageal fistula

OBJECTIVES

Tracheoesophageal fistula (TEF) is characterized by abnormal connectivity between the posterior wall of the trachea or bronchus and the adjacent anterior wall of the oesophagus. Benign TEF can result in serious complications; however, there is currently no uniform standard to determine the appropriate surgical approach for repairing TEF.

METHODS

The PubMed database was used to search English literature associated with TEF from 1975 to October 2023. We employed Boolean operators and relevant keywords: 'tracheoesophageal fistula', 'tracheal resection', 'fistula suture', 'fistula repair', 'fistula closure', 'flap', 'patch', 'bioabsorbable material', 'bioprosthetic material', 'acellular dermal matrix', 'AlloDerm', 'double patch', 'oesophageal exclusion', 'oesophageal diversion' to search literature. The evidence level of the literature was assessed based on the GRADE classification.

RESULTS

Nutritional support, no severe pulmonary infection and weaning from mechanical ventilation were the 3 determinants for timing of operation. TEFs were classified into 3 levels: small TEF (<1 cm), moderate TEF (≥1 but <5 cm) and large TEF (≥5 cm). Fistula repair or tracheal segmental resection was used for the small TEF with normal tracheal status. If the anastomosis cannot be finished directly after tracheal segmental resection, special types of tracheal resection, such as slide tracheoplasty, oblique resection and reconstruction, and autologous tissue flaps were preferred depending upon the site and size of the fistula. Oesophageal exclusion was applicable to refractory TEF or patients with poor conditions.

CONCLUSIONS

The review primarily summarizes the main surgical techniques employed to repair various acquired TEF, to provide references that may contribute to the treatment of TEF.

Successful Repair of Bronchoesophageal Fistula Through Uniportal Video-Assisted Thoracoscopic Surgery

This report describes a case of successful repair of bronchoesophageal fistula through uniportal video-assisted thoracoscopic surgery. A 79-year-old female patient presented with persistent cough and aspiration pneumonia. Chest computed tomography and esophagography showed a bronchoesophageal fistula at right side wall of mid to lower esophagus. Esophagogastroduodenoscopy confirmed a fistula in the esophageal diverticulum. Surgical treatment was planned. The operation was performed through uniportal video-assisted thoracoscopic surgery. The patient was discharged 6 days postoperatively without any complication. No recurrence has been observed during 3 months follow-up in the outpatient clinic to date.

Challenging tracheal resection anastomosis: Case series

OBJECTIVES

This study was conducted to review our experience in Otorhinolaryngology Department, Mansoura University Hospitals, Egypt, in the last 2 years in the management of high-risk patients who underwent cricotracheal resection due to different pathologies.

METHODS

This case series included nine patients with severe, grade III or IV subglottic / cervical tracheal stenosis. These patients were considered high risk patients due to unusual pathology / etiology of stenosis or associated surgical field morbidity. Four patients had recurrent stenosis after previous unsuccessful cricotracheal resection, three patients had subglottic stenosis due to external neck trauma which compromised the surgical field. One patient had upper tracheal neoplasm, and in 1 patient there was upper tracheal stenosis associated with tracheo-esophageal fistula.

RESULTS

Successful decannulation was achieved in all patients (n = 9) without any reported major intraoperative or postoperative compilations.

CONCLUSION

Cases of subglottic / upper tracheal stenosis due to uncommon pathologies like neoplastic lesions, external neck trauma compromising the surgical field and revision cricotracheal resection, can be successfully managed by cricotracheal resection. However, a highly skilled team, well familiar with these surgeries, is mandatory to achieve an optimum outcome.

[Surgical treatment of esophagotracheal and esophagobronchial fistulas]

BACKGROUND

Esophagotracheal and esophagobronchial fistulas are pathological communications between the airway system and the digestive tract, which often lead to major pulmonary complications with a high mortality. Endoscopic treatment is the primary therapeutic approach; however, in cases of failure early surgical treatment is obligatory.

METHODS

This article describes the clinical course of patients with esophagotracheal and esophagobronchial fistulas treated in this hospital over a period of 10 years. Patients were retrospectively analyzed with respect to the etiology of fistulas, management, in particular to the operative procedures, complications and outcome.

RESULTS

Between 2009 and 2019, a total of 15 patients with esophagotracheal and esophagobronchial fistula were treated in this hospital. Of these 12 underwent an endoscopic intervention, of which 5 were successful. In total, eight patients needed surgical intervention, six of the eight surgically treated patients recovered fully, one had a recurrent fistula, which was successfully treated by subsequent endoscopy after surgery and one patient died.

DISCUSSION

Management of esophagotracheal and esophagobronchial fistulas is challenging. This retrospective analysis reflects the published data with a success rate of endoscopic treatment in approximately 50%. Surgical intervention should be carried out after unsuccessful endoscopic treatment or if endoscopic treatment is primarily not feasible. Direct closure with resorbable sutures or reconstruction with alloplastic or allogeneic material should be preferred. For larger defects or high proximal esophagotracheal fistulas local transposition of muscular flaps or free muscular flaps play a major role. During operative closure of high intrathoracic or cervical fistulas, intraoperative neuromonitoring can be useful to prevent nerve damage.

Surgery for intrathoracic tracheoesophageal and bronchoesophageal fistula

Benign tracheoesophageal fistula (TEF) results from an abnormal communication between the posterior wall of the trachea or bronchi and the adjacent anterior wall of the esophagus. It can be acquired or congenital. The onset of the TEF has a negative impact on the patient's health status and quality of life because of swallowing difficulties, recurrent aspiration pneumonia, and severe weight loss. Several acquired conditions may cause TEF. The most frequent is prolonged orotracheal intubation (75% of the cases). Usually, there is an erosion of the tracheal and esophageal wall by the continuous pressure between the endotracheal tube and the esophageal wall; particularly in the presence of a nasogastric or feeding tube within the esophageal lumen. Furthermore, tracheal stenosis is often associated, and adds complexity to the disease. Preparation for the surgical procedure may take weeks or even months. It includes definitive weaning from mechanical ventilation, treatment of respiratory infection, physiotherapy, and correction of malnutrition through enteral feeding. Surgical repair of a TEF is an elective procedure. It consists of division of the fistula, suture of the esophagus and trachea and protection of the suture lines with a buttressed muscle flap. TEF repair is a complex and challenging procedure, thus, high morbidity and mortality are expected. Nonetheless, surgical management yields excellent long-term results, and it should be considered the first-line treatment for this condition. Definitive fistula closure occurs in about 90-95% of the cases.

Surgical management of acquired tracheo/bronchoesophageal fistula associated with esophageal diverticulum

Background

The reports on acquired tracheoesophageal fistulas (TEFs) or bronchoesophageal fistulas (BEFs) associated with traction esophageal diverticula (TED) are rare. Here, we present our experience of six cases.

Methods

Between Jan. 2015 and Jun. 2016, 6 patients were admitted to our department for TEF/BEFs combined with esophageal diverticula. Clinical data of the 6 patients were retrospectively reviewed.

Results

All orifices of TEF/BEF in the esophagus side opened at the diverticula wall. The orifices in the airway side were 2 at the carina and 4 at the right intermediate bronchus. All six patients received the same intervention: a limited diverticulectomy with the fistula resection was done in the esophagus; separate layers of repair were performed for the defect in the esophagus; the muscle flap interposition was used in all six cases. All postoperative courses were uneventful. No recurrence fistula and symptomatic diverticula occurred. The airway and esophagus were patency during a median of 9-month follow-up.

Conclusions

Acquired TEF/BEFs caused by esophageal diverticula can be treated successfully by surgery. A limited diverticulectomy is sufficient to ensure enough esophagus remodeling.

Magnetic Twin Stent for Short-Term Palliation of Acquired Nonmalignant Tracheoesophageal Fistula

Through a tracheostomy with a rigid esophagoscope in the esophagus, the authors simultaneously placed self-made magnetic twin stents in a critically ill patient with high tracheoesophageal fistula. The operation took 17 minutes. Oral nutrition was started immediately. The stents were checked and changed after the months 3, 7, and 14. At 18 months, a tracheal resection and esophageal reconstruction through a partial median sternotomy was completed successfully. The magnetic twin stent technique can temporize critically ill patients with an acquired nonmalignant tracheoesophageal fistula until they become operable.

A Modified Tracheal Transaction Approach for the Repair of Nonmalignant Tracheoesophageal Fistulas: A Report of 5 Cases

BACKGROUND

A postintubation tracheoesophageal fistula is a rare complication of a tracheotomy. Surgical repair is the only viable option for these patients, but the repair techniques presented in the literature vary.

METHODS

We used a modified tracheal transaction approach to repair 5 cases of nonmalignant tracheoesophageal fistulas. The procedure was performed with a low cervical collar incision, and the trachea was transected directly. All the procedures were only carried out in the surgical field created by tracheostomy and paratracheal and esophageal dissection was no longer necessary. The esophageal and tracheal walls were separated. Then, a 2-layer longitudinal suture was used for esophageal reconstruction, and end-to-end anastomosis with excessive cartilage resection was used for tracheal reconstruction.

RESULTS

A successful 1-stage repair of both the esophagus and the trachea was achieved in 4 cases. The remaining case had a tracheostomy fistula and required a second-stage reconstruction for a long (5.5 cm) defect of the tracheal membrane. No perioperative complications occurred, and all gastric tubes and tracheostomies were removed within 3 months of surgery.

CONCLUSION

Based on our primary experience, this modified tracheal transection approach can be considered an appropriate choice for the reconstruction of nonmalignant tracheal fistulas.

Pharyngeal perforation and tracheopharyngeal fistula caused by foreign body impaction

Development of a tracheopharyngeal fistula after pharyngeal perforation is an uncommon occurrence. As a result, published guidance for management of this rare type of aerodigestive tract fistula is limited. We describe the workup and management of a traumatic tracheopharyngeal fistula caused by foreign body impaction. A conservative, endoscopic treatment strategy with broad-spectrum antibiotics, transnasal drainage, and covered tracheal stent placement was used. The stent was removed after 4 weeks, and complete closure of the fistula tract was confirmed by endoscopy and contrast esophagram. Although tracheopharyngeal fistulae are rare and operative treatment can be complex, this case demonstrates that conservative management with antibiotics, drainage, and endoscopic stenting can be successful in select patients.

Application of ECMO to the treatment of benign double tracheoesophageal fistula: report of a case

This report presents the extracorporeal membrane oxygenation (ECMO)-assisted surgical as a treatment of benign double tracheoesophageal fistula. The patient was a 43-year-old woman who presented the airway obstruction for 3 weeks after the esophagus metal stent implantation for the tracheoesophageal fistula 1 year ago. The airway obstruction was due to the expansion and piercing of the metal stent through the upper part of the esophagus into the tracheal cavity. In view of the failure of endotracheal intubation, we finally used ECMO-assisted surgery to remove the stent. And at the same time, cervical esophagostomy externa, exclusion of the thoracic tracheoesophageal fistulas and gastrostomy were performed.

Transtracheal esophageal stent removal: a case-series

Benign esophagorespiratory fistula is a rare but often lethal affection and difficult to cure. Possible treatments are surgery or esophageal stenting but may fail and cause respiratory failure. Two patients with spontaneous esophagorespiratory fistula after chemoradiotherapy for an esophageal malignancy were both treated by esophageal exclusion but esophageal stent were left in place. The esophageal stents were transtracheally removed through the fistula. The removals were successful, patients could leave Intensive Care Unit and returned home. Transtracheal esophageal stent removal is technically possible but very risky. Such situations must be avoided: esophageal stents must absolutely be removed before esophageal exclusion.

Surgical treatment of nonmalignant tracheoesophageal fistula: a thirty-five year experience

BACKGROUND

Acquired nonmalignant tracheoesophageal fistula in the adult patient develops in a variety of conditions. We have applied surgical closure with success for 35 years.

METHODS

From 1975 to 1991, 38 patients underwent surgical repair of a tracheoesophageal fistula. A retrospective study of 36 additional patients undergoing surgical repair from 1992 to 2010 was conducted.

RESULTS

The most common causes were postintubation injury (n=17, 47%), trauma (n=6, 17%), prior laryngectomy (n=6, 17%), and prior esophagectomy (n=4, 11%). Four patients presented after failing fistula control with an endoluminal stent. The tracheal defect was closed with resection and reconstruction (n=17, 41%), laryngotracheal resection (n=5, 12%), membranous tracheal repair (n=17, 41%), or repair over a tracheal T tube (n=2, 5%), while esophageal repair consisted of 2-layer closure (n=31, 78%), 1-layer closure (n=6, 15%), esophagostomy (n=1, 3%), end-to-end esophageal anastomosis (n=1, 3%), or full thickness skin graft reconstruction (n=1, 3%). The esophageal and tracheal repairs were buttressed by interposing pedicled muscle or omental flaps in all patients. There was 1 postoperative death (3%). Recurrence after repair developed only in fistulas arising after esophagectomy or laryngectomy (n=4, 11%). Fistula closure was ultimately successful in 34 patients (94%). Twenty-nine patients (83%) resumed oral intake and 25 patients (71%) were breathing without a tracheal appliance.

CONCLUSIONS

Successful closure of benign tracheoesophageal fistula is achieved with several surgical techniques based on buttressed repair and restoration of normal breathing and swallowing. Closure of complex postsurgical fistula may fail. Endoluminal stenting was not found useful.

Repair of nonmalignant postlaryngectomy pharyngotracheal fistula

The repair of nonmalignant postlaryngectomy pharyngotracheal fistulae is not commonly encountered in medical literature. This rare complication can occur years after laryngectomy for cancer and reconstruction of a neopharynx, and is often associated with adjuvant radiation to the area, making the choice of method for surgical repair critical for success. Optimally, a pedicled myofascial flap from the pectoralis major muscle, from outside the field of radiation, is used to reinforce the repair of the fistula. We present 2 rare cases.

[Surgical repair of postintubation esophago-tracheal fistulas: report of two cases surgically repaired]

Persistence of postintubation esophago-tracheal fistulas is a difficult therapeutic problem. Authors present and discuss two successfully operated cases. Surgical reconstruction was done via left lateral cervical approach, including dissection of the fistulous tract, closure of the defect on both sides by suture, exclusion of the esophagus with a linear stapler beyond a loop esophagostomy, separation the suture lines with interposing of omohioid muscle flap, and making a Pezzer-catheter splinted esophagostomy. In the first case the spontaneous recanalization of the occluded esophagus was prolonged and the fistula recurred. Reoperation was done by the same procedure without exclusion of the esophagus. The second patient needed intervention because of the prolonged closure of esophagostomy. Recovery of both patients was successful. In conclusion, it can be stated that adaptation of surgical techniques for the individual pathologic situation helped the authors to find the way to the successful outcome.
