Oesophago-pleural fistula is an uncommon complication after pneumonectomy, usually related to high morbidity and mortality. Due to its rarity and heterogeneous clinical presentation, its diagnosis and management are challenging issues. Here, we report the case of a patient with a history of pneumonectomy for a tracheal tumour, who developed an asymptomatic oesophago-pleural fistula 7 years after primary surgery. In consideration of the patient's good clinical status and after verifying the preservation of respiratory and digestive functions, a bold conservative approach was adopted. Five-year follow-up computed tomography did not disclose any sign of recurrence of disease and showed a stable, chronic fistula., (© The Author(s) 2019.

Atrioesophageal fistula (AEF) is a potentially lethal complication of catheter radiofrequency ablation for atrial fibrillation. A 49-year-old man with paroxysmal atrial fibrillation who underwent catheter ablation around the pulmonary vein was admitted 31 days after the procedure, suffering seizures and fever. Magnetic resonance imaging of the brain showed ischemia and multiple lesions of acute infarction in the right occipital lobe of the cerebrum. Computed tomography (CT) of the chest showed a small accumulation of air between the posterior left atrium and the esophagus, suggesting an AEF. Endoscopic snaring of the esophageal mucosa, repeated a few times, supported by nil by mouth and antibiotic therapy, resulted in improvement of his condition with no recurrence of symptoms. Subsequent chest CT scans confirmed disappearance of the leaked air and the patient was discharged home 45 days after admission with no neurological compromise.

The purpose of this review is to understand the epidemiology, clinical features, etiopathogenesis, and management of atrioesophageal fistula (AEF) after atrial fibrillation (AF) ablation. The incidence of AEF after AF ablation is 0.015%-0.04%. The principal clinical features include fever, dysphagia, upper gastrointestinal bleeding, sepsis, and embolic strokes. The close proximity of the esophagus to the posterior left atrial wall is responsible for esophageal injury during ablation. Prophylactic proton pump inhibitors, esophageal temperature monitoring, visualization of the esophagus during catheter ablation, esophageal protection devices, and avoidance of energy delivery in close proximity to the esophagus play an important role in preventing esophageal injury. Early surgical repair or esophageal stenting are the mainstay of treatment. Eliminating esophageal injury during AF ablation is of utmost importance in preventing AEF. A high index of suspicion and early intervention is necessary to prevent fatal outcomes., (Copyright © 2014 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.)

A 46-year-old woman underwent a Belsey Mark IV antireflux procedure 2 months before admission to the intensive care unit. She had recurrent episodes of major gastrointestinal hemorrhage before the diagnosis of an aortoesophageal fistula was made by computed tomographic scan. A successful urgent endovascular repair was performed in combination with prolonged antibiotic treatment. The patient recovered well after a hospital stay of 3 months, and is still in clinical follow-up at our hospital >2 years after diagnosis., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Aorto-oesophageal fistula is a rare and often fatal condition due to pathologies of the aorta and oesophagus. Recently, a new aetiology for aorto-oesophageal fistulas has been detected, namely, decubitus of an aortic endovascular prosthesis positioned in the presence of aneurysms. The symptoms are those of Chiari's triad: (1) chest pain and/or dysphagia (2) haematemesis (3) massive haematemesis. If the patient is haemodynamically stable the gold standard diagnostic examination is a CT scan with contrast medium. Aorto-oesophageal fistulas are characterised by a rapidly worsening acute clinical presentation and high postoperative morbidity and mortality. The treatment of aorto-oesophageal fistula is divided into three progressive steps: (1) control of bleeding; (2) prevention of mediastinitis; (3) oesophageal repair. We report a case of a 59-year-old male patient with an aorto-oesophageal fistula due to the decubitus of an endovascular aortic prosthesis previously positioned for a traumatic aneurysm of the descending aorta. We controlled the bleeding in emergency with a Sengstaken-Blakemore tube. Since the cardiovascular surgeons excluded any intervention, we executed a bipolar oesophageal exclusion in our department of general surgery and subsequently positioned a self-expanding oesophageal prosthesis by a retrograde route. The patient survived for 7 months, the cause of death being septic shock.

Purpose: To evaluate delayed complications after esophageal expandable metallic stent placement., Materials and Methods: From April 1993 to December 1997, 90 expandable metallic stents were placed in 82 consecutive patients with inoperable malignant esophageal obstruction (n = 49) or malignant esophagorespiratory fistula (n = 33). Stents used included covered Gianturco-Rosch Z stents (n = 20), Wallstents (covered, n = 31; uncovered, n = 13), and Ultraflex stents (covered, n = 8; uncovered, n = 10). Patients were followed prospectively and monitored for delayed complications, defined as major (hemorrhage, tracheal compression, stent migration, perforation or fistula formation, granulomatous obstruction, tumor ingrowth and overgrowth, funnel phenomenon, and stent covering disruption) or minor (reflux, chest pain, and food impaction)., Results: Mean survival was 4.5 months after stent placement (range, 3 weeks to 26 months). The overall incidence of delayed complications was 64.6%, with 17 patients (20.7%) experiencing more than one complication. The rates of delayed complications in patients with Z stents, Wallstents, and Ultraflex stents were 75.0%, 68.1%, and 44.4%, respectively (P <.05). Most complications were life-threatening and occurred more frequently when stents were placed in the proximal third of the esophagus, compared with more distally (P <.05). Thirteen patients (15.9%) died from complications directly related to stent placement., Conclusion: Esophageal stent placement for malignant obstruction or fistula is associated with a substantial incidence of delayed complications.

The esophago-pericardial fistula is a rare disease that causes a rather high mortality. Up to now less than 70 cases were published in the literature. The authors report an esophago-pericardial fistula caused by recurrent esophageal tumor one year after resection in the lower third esophagus for esophageal cancer. With conservative treatment the patient was kept alive for a month. No case report can be found in the literature of an esophago-pericardial fistula of the same etiology.

We experience a case of esophagopleural fistula successfully cured by conservative therapy after the lung cancer operation. A 46-year-old man was received middle and lower lobectomy for adenoid cystic carcinoma of the right lung. Complication of empyema associated with an esophagopleural fistula occurred on postoperative 4th day. Conservative therapy of nothing by mouth, intravenous hyperalimentation and antibiotics was started. Three thoracic drains were inserted and the thoracic irrigation of total 3,000 ml warm saline per day twice on one day was continued. The esophagopleural fistula was closed on 6th week and the patient was discharged on 11th week after the therapy start. This complication is much rare, but recent advance in the diagnostic methods seemed to increase the indication of conservative therapy in future.

Purpose: To prospectively evaluate the clinical efficacy of polyethylene-covered metallic Z-stents in treatment of dysphagia secondary to malignant esophageal obstruction and esophagorespiratory fistula., Materials and Methods: Thirty-five patients with dysphagia due to malignant esophageal obstruction (n = 32) and esophagorespiratory fistula (n = 3) were treated with polyethylene-covered Gianturco-Rösch Z-stents., Results: Thirty-nine stents were placed in 35 patients. Stent placement was technically successful in all patients. Improvement in dysphagia was achieved in 34 of 35 patients. The average dysphagia score decreased from 3.1 (dysphagia to liquids) to 0.6 (essentially normal diet). An esophagorespiratory fistula was completely sealed in two of three patients. All 35 patients were followed up clinically at 1 day and 1 week and at 3-month intervals (range, 1 week to 18 1/2 months; mean, 4.8 months). Recurrent dysphagia or aspiration occurred in only three of 34 (9%) patients whose disease was initially palliated and was easily treated in all cases. Nine complications occurred in eight patients (23%) and included chest pain that required analgesia (n = 3), food impaction (n = 1), stent migration (n = 2), and upper gastrointestinal tract hemorrhage (n = 3)., Conclusion: Polyethylene-covered stents are a relatively safe and effective means of long-term palliation in patients with severe malignant esophageal obstruction and esophagorespiratory fistula. These stents are easily deployed, and the rate of stent migration is relatively low.

A unique, previously undescribed case of iatrogenic perforation of a pharyngeal pouch which resulted in pharyngo-oesophageal fistulation is described. The correct management of such complications is discussed.

We report a case of fistula between a silicotic mediastinal lymph node and the esophagus with protrusion of a stiff and darkish concretion into the oesophageal lumen. The patient, a 68-year-old coal miner, presented with cough since a few months and the lesion was revealed by haematemesis. The general course was rapidly favourable. Association with tuberculosis was recognized only a few months later.

Two cases are presented in which healing of oesophageal fistula was achieved by the radiologically-guided placement of tissue adhesive (enbucrilate, Histoacryl). With this relatively simple procedure, further surgical intervention under general anaesthesia was avoided.

Nine self-expanding silicone-coated modified Gianturco metal stents were inserted in 8 patients (mean age, 58.2 years) for palliation of malignant esophagorespiratory fistulas caused by esophageal (n = 5) or bronchial (n = 3) carcinoma. One patient with a fistula above a 12-cm-long malignant stenosis received two overlapping stents. The implantation procedure was well tolerated by all patients under intravenous sedation and analgesia. After release, the stents expanded to their full diameter, leading to complete occlusion of the fistulas and bridging of the concomitant stenoses. Two patients with lung cancer received an additional tracheobronchial stent before esophageal stent insertion. Failure to maintain complete contact between the proximal stent margin and the esophageal wall led to insufficient sealing of the fistula of 1 patient and recurrent aspiration, manifested 6 days after stent implantation (overall success, 87.5%). The other patients could swallow semi-solid food until death. Seven patients died of advanced metastatic disease after 21 to 121 days (mean, 54 days) and 1 patient of massive hemoptysis 10 days after stent placement, which could be regarded as a complication (procedure-related mortality rate, 12.5%). These preliminary results suggest that peroral insertion of the modified silicone-coated Gianturco stent is a rapid, reasonably safe, and effective procedure for palliation of malignant esophagorespiratory fistulas.

Purpose: To prospectively evaluate the clinical efficacy of covered metallic Z stents in the treatment of esophagorespiratory fistulas (ERFs)., Patients and Methods: Twelve patients with severe aspiration symptoms from malignant ERFs were treated with silicone-covered, metallic, self-expanding Gianturco-Rösch Z (GRZ) stents., Results: Fluoroscopically guided stent placement was successful and well tolerated in all patients. Immediate postprocedural endoscopy and esophagography showed excellent coverage of the fistulas in all cases. Aspiration symptoms were completely relieved in eight of 12 patients (67%). Four of 12 patients (33%) were improved and able to eat a soft diet. There were no stent-related deaths. Nine patients have died and three patients are alive. Mean follow-up for the entire group was 3.9 months (range, 1 week to 10.5 months). Nonfatal complications occurred in three of 12 patients (25%). Complications included one membrane disruption and one granulomatous reaction with a slight upward stent migration., Conclusion: GRZ stents are an effective and safe means of palliation in patients with malignant esophagorespiratory fistulas.

Purpose: To evaluate the effectiveness of a polyurethane-covered Gianturco stent in the palliative treatment of malignant esophageal stricture and fistula., Patients and Methods: Twenty-seven patients with recurrent stricture (n = 24), fistula formation (n = 8), or both (n = 5) underwent palliative treatment for aphagia (n = 15) or dysphagia (n = 12). Eight patients had fistulas to the respiratory tract or mediastinum. A 15-F delivery sheath system was passed through the stricture; the inner dilator was removed, and the stent was compressed into the sheath and advanced with a pusher catheter. Follow-up included chest radiography for 3 days and monthly esophagography or endoscopy., Results: Covered stents occluded fistulas and opened strictures in 100% of patients. Food intake was upgraded to liquids in 7% of patients, to soft foods in 37% and to regular foods in 56%. New stricture or fistula occurred in 4% and 7% of patients, respectively. Stent migration occurred in 15% of patients. Twenty-one patients died after stent placement, and average life expectancy was 11 weeks., Conclusion: A polyurethane-covered Gianturco stent is effective in the palliation of advanced malignant esophageal strictures and fistulas.

Over a 14-year period, we observed eight cases of esophagopleural fistula after pneumonectomy for cancer (n = 7) or infectious lung disease (n = 1). In 2 patients, the fistula was probably related to an intraoperative esophageal injury. Two others had mediastinal cancer recurrence, whereas a fistula developed in 4 without any malignancy. Patients presented with empyema, and a contrast swallow procedure disclosed an esophagopleural fistula. Two patients with recurrent cancer were managed conservatively with chest tube insertion and died within 3 months. A patient with chronic empyema had a delayed diagnosis of esophagopleural fistula 2 years after a presumed intraoperative injury; he was managed with thoracoplasty and feeding gastrostomy and died 12 months later. Five patients had an attempt at curative treatment. A single patient underwent thoracoplasty and bipolar exclusion of the esophagus and had secondary reconstruction with a coloplasty; he died with postoperative peritonitis. Four patients underwent thoracoplasty and muscle flap repair of the esophagus. There was 1 operative death from pulmonary embolism, whereas 3 patients recovered and are well with follow-up of 18 months, 2 years, and 5 years, respectively. We conclude that the prognosis of esophagopleural fistula is ominous when associated with cancer recurrence. A curative approach should combine direct repair of the esophagus with a muscle flap and eradication of the associated empyema with thoracoplasty. This aggressive treatment is addressed to debilitated patients and carries high rates of mortality and morbidity.

A case of esophageal small cell carcinoma with cervical node metastases and an esophago-mediastinal fistula was treated successfully by chemoradiotherapy. The fistula, after irradiation, was handled successfully by esophageal intubation, followed by infusional 5-fluorouracil and cisplatinum chemotherapy, resulting in the closure of the fistula. Two courses of concurrent chemoradiotherapy, followed by additional cisplatinum and etoposide chemotherapy, were administered. The tumor, including the cervical lymph node metastases, disappeared completely after the treatment.

Endoscopic placement of an esophageal endoprosthesis is the most rational therapy for relieving the distress of malignant esophago-pulmonary fistula. The commercial prostheses are very expensive for widespread use in India. We have indigenously prepared silicone rubber endoprostheses. The wall of the prosthesis was hardened in a graded manner until the desired resistance to compression with flexibility is achieved. This prosthesis was placed successfully in five patients with malignant esophago-pulmonary fistula. Dysphagia and aspiration were relieved in all the patients. One patient had delayed esophageal perforation and died of massive bleeding 3 weeks after the placement of prosthesis. The indigenous endoprosthesis is cost-effective and safe.

Aortoesophageal fistula (AEF) is a relatively rare but life-threatening cause of upper gastro-intestinal bleeding. The clinical characteristics of AEF are so unique that a presumptive bedside diagnosis can be made at the time of presentation. In the past decade, surgical management has improved to the point that cure is now possible. For these reasons, we have reviewed the literature. We summarize our findings with respect to the etiology and clinical characteristics of AEF. Further, we discuss the diagnostic modalities that may be used to confirm the diagnosis, and the therapeutic modalities available to slow the hemorrhage, so as to allow time to correct the anatomic defect.

Successful treatment of an eight-year-old esophagopleural fistula by means of endoscopic cauterization with an alkaline solution is reported. Previous therapeutic attempts with other more conventional measures had failed. The technique of the successful treatment is described. No complications could be attributed to its use.

Esophageal perforation can be a difficult management problem in a patient with spinal cord injury. Meticulous history taking and physical examination are essential for diagnosis. A quadriplegic patient with the unusual complication of esophagocutaneous fistula following anterior cervical fusion was admitted to our spinal cord injury service for intensive rehabilitation. Although early surgery is the usual treatment, conservative management with emphasis on local wound care can lead to satisfactory healing of the fistula. Because of the halo vest traction device used to maintain the surgical reduction of the cervical fracture, it was decided to treat the patient's fistula conservatively. Difficulties with feeding, diarrhea, and recurrent drainage that complicated the nonoperative treatment were successfully managed while the patient underwent intensive and comprehensive rehabilitation. The patient was discharged ambulating independently without any orthotic device a day after complete closure of the esophagocutaneous fistula.

The authors report the first case in Senegal of an esophagotracheal fistula isolated in a suckling child 1,1/2 months old, and stress: the clinical profile and the rarity of this deformity; the difficulties of providing for such patients in view of the close medico-surgical collaboration required.

The patient was a 43-year-old woman, who had undergone a right middle and lower lobectomy for adenocarcinoma of the lung. An esophagobronchopleural fistula developed two months after the operation. It was treated by a combined procedure consisting of pedicle flap closure of the fistula and thoracoplasty. The esophagobronchopleural fistula recurred two days later, however, and another pedicle flap closure with fenestration of the chest wall were performed in a third operation. A bronchopleural fistula then recurred, after which it was treated by conservative therapy including intravenous hyperalimentation, frequent dressing changes and systemic administration of appropriate antibiotics. It closed spontaneously 23 days after surgery, in spite of this being a very rare but serious complication very difficult to treat and cure. From our experience with this particular case, we recommend, for treating esophagobronchopleural fistulas, proper drainage, antibiotic therapy, intravenous hyperalimentation and packing of the empyema space, together with closure of the fistula using a muscle or pleural flap.

Experiences from 14 disruptions of oesophageal sutures and with 8 cases of recurrent fistula from 1973 to 1982 are described. Healing of an early oesophageal insufficiency could be achieved by conservative means in 3 newborns. Conservative therapy seems to be possible if life-threatening clinical conditions are reduced effectively. 6 oesophago-pulmonary and recurrent oesophago-tracheal fistulas were closed operatively, two cases closed spontaneously.
