Aortoesophageal fistula due to esophageal ulcer

Aortoesophageal fistula is a rare but fatal disease. Many such fistulas are caused by an aortic aneurysm, a previous operation, or esophageal disease. We report a case of aortoesophageal fistula due to an esophageal ulcer. A 66-year-old man suffered massive hematemesis; he was diagnosed as having an aortoesophageal fistula due to an esophageal ulcer after examination by upper endoscopy, computed tomography, and angiography. He had no aortic aneurysm, nor was there a history of a previous operation. An emergency operation was performed, but we could only accomplish closure because clamping of the aorta was impossible, and the source of the bleeding could not be established. He died 4 days later after sudden hemorrhage. Surgical outcome depends on early surgical intervention before massive hemorrhage occurs.     

Aortoesophageal fistula

With the advent of cardiovascular and bypass procedures, aortoesophageal fistula has progressed from the stage of a pathologic curiosity to a treatable lesion. Although the causes of aortoesophageal fistula are varied, a remarkably consistent clinical picture emerges from study of this condition. Chiari's triad of midthoracic pain, sentinel hemorrhage, and a symptom-free interval followed by fatal exsanguination remains the most important clinical finding today. Although contrast esophagography, esophagoscopy, and aortography are important diagnostic aids, immediate left thoracotomy may be the only means of making the diagnosis and saving the patient when hemorrhage is profuse. In most cases (80 per cent of the present series) there is a symptom-free period varying from hours to days from the original sentinel hemorrhage to the final exsanguination. This permits the informed surgeon trained in cardiovascular technics an opportunity to salvage some of these patients.The various methods of aortic and esophageal repair are discussed.     

Aortoesophageal fistula secondary to reflux esophagitis

Aortoenteric fistula is a rare cause of massive upper gastrointestinal bleeding and is in the overwhelming majority of cases due to erosion of a suture line of a prosthetic vascular graft into the bowel. We report the case of a massive fatal gastrointestinal hemorrhage from an aortoenteric fistula secondary to erosion from reflux esophagitis. Proper management requires expedient radiographic and endoscopic evaluation, and even with appropriate management mortality remains extremely high.     

Aortoesophageal fistula caused by foreign body.

Aortoesophageal fistula is rare. A woman who developed aortoesophageal fistula after swallowing a fish bone developed hematemesis. 7 days later, we resected a false aneurysm near the left subclavian artery and repaired this section twice. Despite these measures, the woman died on hospital day 21. The clinical diagnosis was massive hematemesis from an infected aortic wall. The method of diagnosis, control of infection, and operative repair of aortoesophageal fistula are discussed.     

Aortoesophageal fistula induced by foreign bodies.

Two patients with aortoesophageal fistula induced by foreign bodies were surgically treated during a period of 10 years. The first patient was surgically treated through a right thoracotomy, which failed on account of exsanguination. In the second patient, a Sengstaken-Blakemore tube was inserted for esophageal tamponade. The aorta was successfully repaired through a left thoracotomy after occlusion of the esophagus and the aorta above and below the fistula. Therefore, we recommend preoperative esophageal tamponade and occlusion of the esophagus and the aorta through a left thoracotomy as the most successful approach.     

Tracheobronchial necrosis after caustic ingestion.

Between 1968 and 1988, 679 patients were hospitalized for ingestion of caustic substances, and 87 had severe caustic burns of the entire esophagus, together with panparietal necrosis. Twenty-one of them had tracheobronchial necrosis with perforation. Fifteen have not been operated on; six have had operations, with success in four. We describe an original technique for repairing these tracheobronchial perforations with a pulmonary patch.     

Aortoesophageal perforation following ingestion of razorblades with massive haemothorax.

Aortoesophageal fistula is a rare complication of foreign body ingestion. Typically having ingested a fish or chicken bone, the patient complains of chest pain or discomfort and/or may present with massive gastrointestinal bleeding, which in all but rare cases is fatal. The pathological mechanism may involve perforation and direct communication of oesophagus and aorta usually at the level of the aortic arch; or more usually following oesophageal perforation, the subsequent mediastinal abscess leads to necrosis of the aortic wall. Torrential haemothorax as a result of such a process has not been previously described, though it has undoubtedly occurred. We present a case of massive haemothorax following deliberate ingestion of razorblades that highlights clinically and radiologically the natural course of such a tragic action.     

Aortoesophageal fistula due to ruptured thoracic aortic aneurysm: case report of successful primary reconstruction of esophagus

We report a successful surgical case of 78-year-old woman with aortoesophageal fistula subsequent to the operation for sealed rupture of thoracic aortic aneurysm. She underwent one-stage operation consisted of esophagectomy, transmediastinal interposition of the stomach and esophagogastroanastomosis, to re-establish the gastrointestinal tract. The patient recovered well postoperatively without infection.     

Aortoesophageal fistula successfully treated by endovascular stent-graft

The case of a patient with an aortoesophageal fistula is presented, which was caused by ingestion of a chicken bone and was treated by endovascular stent-graft placement and esophagectomy with early reconstruction. The diagnostic and therapeutic options and challenges encountered in treating an aortoesophageal fistula are discussed.     

Free jejunal patch to reconstruct oral scar contracture following caustic ingestion.

Reconstruction of oral scar contracture is often a challenging problem due to the complex structures and functions of the oral cavity. This report describes the treatment of a patient who sustained extensive oral scar contracture following caustic liquid soda ingestion. Surgical release of the scar contracture formed an S-shaped, thin, long defect that was difficult to cover with a conventional flap or skin graft. A jejunal segment was transferred microsurgically as a patch to reconstruct the defect. It sustained a sufficient oral space to provide full opening of the mouth and good movement of the tongue. A free jejunal flap, used occasionally for reconstruction following oral cancer resection, has significant advantages for restoration of function after release of an oral scar contracture.     

Aortoesophageal fistula: case report and literature review

Fistulous communication between the aorta and esophagus is a rare but usually fatal disorder. Esophageal foreign bodies have been reported to cause aortoesophageal fistula rarely. Spontaneous aortoesophageal fistula as a result of atherosclerotic disease of the aorta has not been reported. This article describes a case of aortoesophageal fistula caused by an ulcerated atherosclerotic plaque, which we believe is the first case report implicating such an etiologic factor.     

Management of caustic ingestion in adults

The treatment of 484 adults with caustic ingestion injury is discussed. Signs and symptoms are an unreliable guide to injury and a chest X-ray and fibreoptic endoscopy should be performed as soon as possible. All of the 250 patients who developed superficial lesions of the oesophagus, stomach or duodenum experienced healing without sequelae. Forty-four patients required emergency surgery of whom twenty-four died and oesophagectomy without thoracotomy is now advocated for this group, followed by interval surgery to restore continuity. The remaining 190 patients suffered gastric or oesophageal ulceration without necrosis: 92 recovered without complication, 3 succumbed to aorto-oesophageal fistula, 12 survived following delayed surgery for complications and 83 developed oesophageal and/or gastric stenosis which subsequently required endoscopic or surgical treatment.     

Extensive abdominal surgery after caustic ingestion

OBJECTIVE: To report the authors' experience in extensive abdominal surgery after caustic ingestion, and to clarify its indications. SUMMARY BACKGROUND DATA: After caustic ingestion, extension of corrosive injuries beyond the esophagus and stomach to the duodenum, jejunum, or adjacent abdominal organs is an uncommon but severe complication. The limit to which resection of the damaged organs can be reasonably performed is not clearly defined. METHODS: From 1988 to 1997, nine patients underwent esophagogastrectomy extended to the colon (n = 2), the small bowel (n = 2), the duodenopancreas (n = 4), the tail of the pancreas (n = 1), or the spleen (n = 1). Outcome was evaluated in terms of complications, death, and function after esophageal reconstruction. RESULTS: Five patients required reintervention in the postoperative period for extension of the caustic lesions. There were two postoperative deaths. Seven patients had secondary esophageal reconstruction 4 to 8 months (median 6 months) after initial resection. Three additional patients died 8, 24, and 32 months after the initial resection. Three survivors eat normally, and one has unexplained dysphagia. CONCLUSIONS: An aggressive surgical approach allows successful initial treatment of extended caustic injuries. Early surgical treatment is essential to improve the prognosis in these patients.     

Aortoesophageal fistula--an unusual complication of esophagitis caused by Dieffenbachia ingestion

Aortoesophageal fistula (AEF) is a rare and mostly lethal cause of upper gastrointestinal bleeding in children. We report a successful outcome of surgical treatment after resuscitation of a girl aged 12 1/2 years with AEF as a complication of esophagitis caused by Dieffenbachia ingestion. The girl ate a leaf of Dieffenbachia picta in a suicidal attempt. After 5 weeks of medical treatment of esophagitis, small blood-stained vomitus and melena appeared. Within a few hours, it was followed by a massive gastrointestinal bleeding leading to exsanguination. The girl survived despite the pitfalls in clinical presentation and errors in diagnostic approach and treatment. Emergency exploration of cervical esophagus, followed by laparotomy and thoracotomy, was performed in attempt to find the source of bleeding and to control it. Aortoesophageal fistula was located between the ascending aorta near the origin of the brachiocephalic trunk and thoracic esophagus. Resection of the fistula led to prompt circulatory stabilization. The common houseplant, Dieffenbachia picta, causes edematous swelling of mucus membranes when chewed. Dieffenbachia-caused esophagitis is very rare and this etiology of AEF has not been reported in children.     

The oral implications of caustic soda ingestion in children.

The morbidity related to caustic soda (sodium hydroxide) ingestion is well described in the literature. The majority of publications have concentrated on the effects to the trachea and gastrointestinal tract, with little reference to the oral and peri-oral areas. Accidental ingestion of sodium hydroxide-containing substances is fortunately rare; however the consequences can be devastating. Three cases of children who drank caustic substances are described. Treatment included fitting splints, injecting steroids, local surgical procedures, and the use of dynamic appliances to maintain mouth opening. Despite these interventions, all patients developed severe scarring, resulting in stenosis of the oral musculature and extra-articular ankylosis. There is perhaps a role for further investigation of early use of antiproliferative agents to prevent scarring, more aggressive surgery, and long-term physiotherapy appliance use. These patients require lifelong follow-up.     

Aortoesophageal fistula: alternatives of treatment case report and literature review.

Aortoesophageal fistula (AEF) remains as a life-threatening condition with a high rate of morbidity and mortality. It is usually related to aortic or esophageal disease, and less commonly foreign body ingestion. In spite of several strategies for treatment, there is little consensus regarding the optimal management of this entity. In this paper, we present our experience in successfully managing one patient with AEF by performing open surgical repair. We also include a discussion on criteria for selecting the most appropriate alternative of treatment: open or endovascular repair, based on a review of the literature currently available in MEDLINE.     

Emergency management of caustic ingestion in adults

A study of 57 patients admitted to the Department of Emergency Surgery at the Ospedale Maggiore in Milan between 1980 and 1992 following the recent ingestion of a caustic substance is presented herein. Through this study, an aggressive diagnostic and therapeutic approach has been employed, including early surgery which plays a fundamental role in the prevention of acute hemorrhagic or perforative complications as well as in the development of scar tissue and neoplastic strictures over time. The criteria for early emergency surgery were the presence of endoscopic grade 3 and 4 lesions as well as those on the borderline between grades 2 and 3 with clinical symptoms. In 11 patients with lesions of moderate severity, the treatment of choice was medical therapy, which required subsequent surgical intervention for strictures in 5 patients. In 13 patients with severe lesions, an early surgical approach was performed with a mortality rate of 23%.
