Lung torsion after tracheoesophageal fistula repair: a case report and review of literature

Lung torsion is a very rare event that has been described after trauma, spontaneously, and post-thoracic surgery, with only 8 cases reported in the pediatric literature. We present the first case report of lung torsion complicating tracheoesophageal fistula repair. The diagnosis was suggested on chest ultrasonogram and Doppler and confirmed by computed tomographic scans. On exploration, a 90° rotation of the right middle and lower lobes in a clockwise direction was found. A complete interlobar fissure and an absent inferior pulmonary ligament were identified as predisposing factors. The lobes were untwisted, and lobar fixation was performed to prevent retorsion. Postoperatively, the patient recovered complete lung function, and the patient's chest radiologic and ultrasonographic examination results normalized. Lung torsion is an extremely uncommon event. It causes clinical deterioration in the face of normal arterial blood gases and requires a high index of suspicion for diagnosis. Resection of the twisted lung or lobe may be unnecessary if diagnosis is made early and vascular occlusion is partial. Patients with complete interlobar fissures may benefit from pulmonary lobe fixation as a prophylaxis against occurrence or recurrence of this complication.     

Tracheal diverticula after tracheoesophageal fistula repair: case series and review of the literature

Background

Tracheoesophageal fistula (TEF) is the most common congenital tracheal abnormality, frequently associated with esophageal atresia. Respiratory symptoms are associated with all types of TEF, even after surgical repair of the fistula. Gastroesophageal reflux (GER) with aspiration of gastric contents, structural instability of the airways (tracheomalacia), abnormal respiratory epithelium, abnormal esophageal motility, recurrent TEF, and esophageal stenosis contribute to postsurgical complications.

Methods

We review 7 patients between 4 and 14 years of age with a history of TEF repair and persistent or worsening respiratory symptoms despite conventional airway clearance techniques and treatment of GER.

Results

Bronchoscopic evaluation in all 7 patients revealed tracheomalacia and a diverticulum on the posterior wall of the trachea at the fistula repair site.

Conclusion

We hypothesize that the diverticula impaired airway clearance and contributed to persistent respiratory symptoms. Possible mechanisms for the diverticulum contributing to poor airway clearance include facilitating the pooling of secretions and acting as a “barrier” to the lower airway clearance mechanism. The diagnosis of a diverticulum should be considered early in patients with persistent respiratory symptoms after management of GER and tracheomalacia. Early obliteration of tracheal diverticula might improve respiratory status in some patients.     

Primary repair of tracheoesophageal fistula secondary to disc battery ingestion: a case report

The authors report on a child with tracheoesophageal fistula secondary to disc battery ingestion. Through a low cervical collar incision with limited sternal split, the fistula was primarily repaired, and the omohyoid muscle and thymus were mobilized to cover the suture lines. There are no signs of recurrent fistula 6 months after the operation. The anterior cervical approach with limited sternal split provided excellent access to the fistula. To the authors’ knowledge, this is the first report of successful primary repair of a tracheoesophageal fistula secondary to disk battery ingestion.     

Thoracoscopic repair of H-type tracheoesophageal fistula in the newborn: a technical case report

H-type tracheoesophageal fistula (H-TEF) without esophageal atresia makes up 4% to 5% of esophageal congenital abnormalities. The authors present the thoracoscopic treatment of a 2.47-kg newborn boy with a fistula between the second and third thoracic vertebrae diagnosed by esophagography. Four trocars were used for fistula closure, and tracheal and esophageal suturing were accomplished without intraoperative incident. Five days after surgery, results of a barium swallow excluded anastomotic leaks. The chest tube was removed, and oral feeding was initiated.     

Diagnosis of a proximal tracheoesophageal fistula using three-dimensional CT scan: a case report

Missed proximal tracheoesophageal fistulas (TEF) after repair of an esophageal atresia (EA) with distal TEF are rare. The diagnosis usually is made on the basis of bronchoscopy and esophagoscopy, which can be inaccurate. Recent advances in computerized tomography (CT) have allowed saggital, coronal, and 3-dimensional reconstruction of any structure or organ. The authors report a case in which 3-dimensional CT was used to assist in the diagnosis of a missed proximal TEF in a 16-year-old girl.     

Congenital tracheoesophageal fistula with symptoms commencing at the onset of trauma: Report of a case

Congenital tracheoesophageal fistula without atresia can persist and remain undetected without symptoms until adulthood. We have recently encountered such a rare case and also conducted a review of the literature. Symptoms are commonly present during infancy, but occasionally patients do not develop symptoms until adulthood. In this case, it is suggested that the symptoms commenced after the redundant mucosal flap or membrane was broken due to a trauma to the chest.     

An extremely rare abnormality of a double tracheoesophageal fistula without atresia of the esophagus; a case report and review of the literature

Tracheoesophageal fistulas without atresia of the esophagus are rare abnormalities of the upper gastrointestinal tract with an incidence rate of between 1% and 5%. Even more infrequent are 2 tracheoesophageal fistulas without atresia of the esophagus. This case report illustrates the history of an infant with 2 tracheoesophageal fistulas. The corresponding literature was reviewed, and a diagnostic algorithm was described.     

The role of preoperative CT scan in patients with tracheoesophageal fistula: A review

Purpose

The morbidity and mortality associated with esophageal atresia with or without a fistula make it a challenging congenital abnormality for the pediatric surgeon. Anatomic factors like inter-pouch gap and origin of fistula are not taken into consideration in various prognostic classifications. The preoperative evaluation of these cases with computerized tomography (CT) has been used by various investigators to delineate these factors. We reviewed these studies to evaluate the usefulness of this investigation in the intra operative and post operative period.

Materials and Methods

A literature search was done on all peer-reviewed articles published on preoperative computed tomography (CT) in cases of tracheoesophageal fistula using the PUBMED and MEDLINE search engines. Key words included tracheoesophageal fistula, computerized tomography, virtual bronchoscopy, and 3D computerized tomography reconstruction. Further, additional articles were selected from the list of references obtained from the retrieved publications. A total of 8 articles were selected for analysis.

Results

In most of the studies, comprising 96 patients, observations noted in preoperative CT were confirmed during surgery. In a study by Mahalik et al [Mahalik SK, Sodhi KS, Narasimhan KL, Rao KL. Role of preoperative 3D CT reconstruction for evaluation of patients with esophageal atresia and tracheoesophageal fistula. Pediatr Surg Int. 2012 Jun 22. [Epub ahead of print]], in 6 patients the fistula could not be identified pre-operatively by CT. One study found a difference of 0.43 cm in the intraoperative gap length compared to that given by CT when compared to +/− 2 mm shown by another [1. Mahalik SK, Sodhi KS, Narasimhan KL, Rao KL. Role of preoperative 3D CT reconstruction for evaluation of patients with esophageal atresia and tracheoesophageal fistula. Pediatr Surg Int. 2012 Jun 22. [Epub ahead of print], 3. Ratan SK, Varshney A, Mullick S, Saxena NC, Kakkar S, Sodhi PK. Evaluation of neonates with esophageal atresia using chest CT scan. Pediatr Surg Int. 2004 Oct; 20(10):757-61.]. Only three studies showed surgical utility of pre-operative CT, and the surgical plan changed based on the CT findings.

Conclusion

The usefulness of pre-operative computerized tomography in cases of tracheoesophageal fistula is controversial. The safety of this technique is questionable due to limited facilities and associated radiation hazards. Further, limited information obtained which may help in changing the surgical plan can easily be managed intra-operatively by careful and meticulous surgery.Overall, the safety concerns outweigh its efficacy. Thus, the use of pre-operative CT scan cannot be generalized and protocolized as a standard of care in the management of tracheoesophageal atresia.     

Triple fistula: management of a double tracheoesophageal fistula with a third H-type proximal fistula

Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is a relatively common congenital condition in which there have been several described anatomical variants. The most common type, EA with distal TEF, comprises more than 75% of cases in many reports. Less commonly, a smaller proximal pouch fistula (H-type) will be associated with this most common variant in 1.4% of these cases. Only 2% of all cases of EA/TEF will have 2 large fistulas between the trachea and esophagus in which the end of the upper esophageal pouch connects terminally to the midtrachea and the distal esophagus arises from the trachea near the carina. Here we describe the management of an infant with this type of EA/TEF who was also found to have an H-type TEF of the proximal trachea. The combination of this type of EA/TEF with an associated H-type TEF or “triple fistula” has been previously described in the literature in only 1 other patient.     

A simple skin flap plasty to repair tracheocutaneous fistula after tracheotomy

The tracheocutaneous fistula after tracheostomy is a complex clinical problem. An ideal fistula closure is still difficult at present though a variety of fistula-closing methods have been reported in the literature. We used a turnover skin flap to cover the fistula. All the procedures were completed at bedside under local anesthesia. The fistula was successfully closed and well healed without complications within 7-9 days. It has been proven that this operation is simple, effective, and safe.     

Platysma myocutaneous flap interposition in surgical management of large acquired post-traumatic tracheoesophageal fistula: A case report

INTRODUCTIONAcquired post-traumatic tracheoesophageal fistula (TEF) is an uncommon entity requiring early diagnosis. Among the many strategies in surgical management, we report a case successfully treated with a single-stage tracheal resection and esophageal repair with platysma myocutaneous interposition flap.PRESENTATION OF CASEA 24-year-old man had a motor vehicle accident with head injury and cerebral contusion who required mechanical ventilation support. Three weeks later, he developed hypersecretion, and recurrent episodes of aspiration pneumonia. The chest computed tomography, esophagogastroduodenoscopy, and bronchoscopy revealed a large TEF diameter of 3 cm at 4.5 cm from carina. Single-stage tracheal resection with primary end-to-end anastomosis and esophageal repair with platysma myocutaneous interposition flap was performed. A contrast esophagography was done on post-operative day 7 and revealed no leakage. He was discharged on post-operative day 10. Esophagogastroduodenoscopy at 1 month revealed patient esophageal lumen. At present he is doing well without any evidence of complications such as esophageal stricture or fistula.DISCUSSIONThere are many choices of myocutaneous muscle flaps in trachea and esophageal closure or reinforcement. The platysma myocutaneous flap interposition is simple with the advantage of reduced bulkiness. Concern on the vascular supply is that flap should be elevated with the deep adipofascial tissue under the platysma to ensure that the flap survival is not threatened.CONCLUSIONThe treatment of acquired TEF with platysma myocutaneous flap is an alternative procedure for a large uncomplicated TEF as it is effective, technically ease, minimal donor site defect and yields good surgical results.     

Endoscopic management of recurrent tracheoesophageal fistula with trichloroacetic acid chemocauterization: a preliminary report

Purpose

Open repair with a second thoracotomy is technically challenging and has a high risk of complications for the treatment of a recurrent tracheoesophageal fistula (RTEF). Therefore, less invasive endoscopic techniques have been developed. Here, we report on the chemocauterization with trichloroacetic acid (TCA) technique for endoscopic management of RTEF.

Methods

Three patients who had an open repair with thoracotomy for congenital tracheoesophageal fistula and were diagnosed with RTEF were included in this study. Rigid ventilating bronchoscopy with telescopic magnification was used to evaluate and manage the RTEF. After identification of the fistula opening, a 50% TCA-soaked small cotton ball was applied in the opening 3 times during each session.

Results

The mean number of procedures was 3.3, and the fistulae were closed in all cases. Closure of the fistula was confirmed by esophagogram and/or bronchoscopy. There were no postoperative complications.

Conclusion

The results of this study showed that chemocauterization with TCA can be safe and effective for the management of RTEF.     

Esophageal atresia and tracheoesophageal fistula with distal esophageal stenosis: preoperative diagnosis

This is a presentation of a case of preoperative diagnosis of apparent esophageal atresia and an apparent distal and tracheoesophageal fistula from a peripheral hospital. After surgery, histopathologic findings showed the absence of cartilage and bronchial glands, suggesting the etiology as a fibromuscular stenosis.

Congenital laryngeal atresia associated with esophageal atresia and tracheoesophageal fistula: a case of long-term survival

Congenital laryngeal atresia (LA) is a life-threatening anomaly in which appropriate perinatal management is essential for survival. The authors report a neonate with LA associated with esophageal atresia (EA) and tracheoesophageal fistula (TEF) who was successfully resuscitated by emergent tracheostomy. Before birth, the patient had a diagnosis of EA based on the findings of polyhydramnios and absent stomach bubble. Immediately after birth, severe respiratory distress, cyanosis, and sternal retraction were evident. Because either endotracheal or esophageal intubation was unsuccessful, an emergent tracheostomy was performed. A direct laryngoscope revealed a subglottic atresia with normal appearance of the vocal cords. Repair of EA with TEF was performed on the third day of life, and the postoperative course was uneventful. In 2 years follow-up, the patient has no mental retardation nor central nervous impairment. Because of the presence of TEF, the antenatal ultrasonogram did not demonstrate the characteristic findings of the congenital high airway obstruction syndrome. This case represents one of the very few reported cases of successful resuscitation of a neonate with an unanticipated LA in which emergent airway management is required immediately after birth.     

Eosinophilic esophagitis and intermediate esophagitis after tracheoesophageal fistula repair: a case series

Background

Eosinophilic esophagitis (EE) is often missed or underdiagnosed in children, particularly in the setting of reflux disease associated with tracheoesophageal fistula (TEF). Intermediate esophagitis (IE) is a recently described condition, which includes characteristics of gastroesophageal reflux disease and EE but does not present with enough eosinophils on biopsy to diagnose EE. Here we present a case series of EE and IE associated with TEF, and their clinical manifestations.

Methods

A retrospective analysis including clinical presentation, endoscopic and pathologic findings, and treatment of 4 patients with EE and 4 patients with IE who presented between 2003 and 2007 was performed.

Results

Male dominance was found equally in both groups (75%), and most patients had a personal history of atopy (87.5%). Food allergies were seen mainly in the EE group (75%). The most frequent primary symptoms in both groups were dysphagia for solids (75%) and for liquids (25%). The median age at diagnosis was 9.8 vs 11.2 years in the EE and IE groups, respectively. On endoscopy, both groups had similar findings including furrows (EE, 75%; IE, 66.6%) and white plaques (EE, 50%; IE, 33.3%). In both groups, almost all patients had basal cell hyperplasia on biopsy (EE, 100%; IE, 75%). Degranulated surface eosinophils (50%) and eosinophilic abscess (25%) were found in the EE group only. Elongated rete papillae were more often seen in EE biopsies (50%) compared with IE biopsies (25%). Peripheral serum eosinophilia was seen in all EE patients and in 33% of the IE patients. The only effective treatment with complete resolution of the symptoms was the topical or systemic application of steroids.

Conclusions

The diagnosis of EE and IE is frequently missed or delayed. Eosinophilic esophagitis should be suspected in reflux disease refractory to conventional treatment, particularly in the setting of TEF. Intermediate esophagitis represents an entity that includes findings of gastroesophageal reflux disease and EE. Endoscopic biopsies are diagnostic for both conditions and allow institution of specific medical treatment.     

Repair of esophageal atresia with tracheoesophageal fistula via thoracotomy: a contemporary series

Background

A recent series detailing thoracoscopic repair of esophageal atresia with tracheoesophageal fistula (EA/TEF) reported lower complication rates compared with historic controls. This study provides a contemporary cohort of patients repaired via thoracotomy for comparison with the recent large multi-institutional thoracoscopic series.

Methods

Records of patients with EA/TEF between 1993 and 2008 were reviewed. Attention was focused on demographics and complications including anastomotic leak, recurrent fistulae, stricture formation, and need for fundoplication.

Results

Seventy-two patients underwent repair of EA/TEF via thoracotomy. Complication rates in the current series compared with the thoracoscopic series were anastomotic leak, 2.7% versus 7.6%; recurrent fistulae, 2.7% versus 1.9%; stricture, 5.5% versus 3.8%; and need for fundoplication, 12% versus 24%. Differences in complication rates did not reach statistical significance. Two children in this cohort developed mild scoliosis attributed to congenital vertebral anomalies, neither of whom required intervention.

Conclusions

Thoracoscopic repair of EA/TEF yielded complication rates similar to this contemporary series; however, trends toward increased anastomotic leaks and greater need for fundoplication were noted. No musculoskeletal sequelae were directly attributable to thoracotomy.     

A gasless abdomen does not exclude distal tracheoesophageal fistula: the value of a repeat x-ray

A “gasless abdomen” in babies with esophageal atresia (EA) has traditionally been thought to imply absence of a distal tracheoesophageal fistula (TEF). We present 3 neonates with a provisional diagnosis of EA, who had a gasless abdomen on an initial x-ray taken within the first 4 hours of life. These children were subsequently shown to have gas in the stomach associated with a distal TEF. Two children were examined on subsequent repeat x-ray of the abdomen, when gas was demonstrated in the stomach. Another child had a laparotomy for a gastrostomy when a distended stomach was found. This baby went on to have a thoracotomy and a routine repair of the distal TEF and an esophageal anastamosis. Based on our data of 65 cases of EA and distal TEF, it is recommended that an x-ray of the abdomen is repeated before surgery is undertaken if the gasless abdomen is documented during the first 4 hours of life.     

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.     

Successful treatment of tracheomalacia associated with esophageal atresia without a tracheoesophageal fistula by aortopexy: Report of a case

Tracheomalacia (TM) is well known as a complication associated with esophageal atresia (EA) and tracheoesophageal fistula (TEF); however, the occurrence of TM requiring surgical treatment in a patient having EA without a tracheoesophageal fistula has never been reported. We describe herein a rare case of TM associated with EA without TEF. Respiratory distress was caused by compression of the trachea by a severely dilated upper esophageal pouch with weakness of the tracheal wall. Aortopexy was performed, and an excellent postoperative result was achieved.
