Truncus arteriosus type A3: complex repair with cryopreserved pulmonary homograft

A 6-year-old girl with truncus arteriosus type A3, one of the rarest anatomic types, underwent corrective surgery using a cryopreserved valved pulmonary homograft. The special anatomic features in this case were individual origin of the pulmonary arteries. The right pulmonary artery came directly off the truncal vessel, whereas the left pulmonary artery was connected to the aortic arch via a stenotic ductus or ductus-like vessel. The preoperative pulmonary blood flow distribution was 94% on the right versus 6% on the left side. The underperfusion of the left lung may have been related to pulmonary hypoplasia due to long lasting stenosis at the left pulmonary artery take off. The postoperative pulmonary blood flow distribution was 67% on the right versus 33% on the left side. The operative and postoperative course has been uneventful; presently, 6 months after the operation, the patient is in improved clinical condition.     

Successful surgical treatment of left atrioesophageal fistula following atrial ablation

A 69-year-old male had catheter-based ablation for atrial fibrillation. He was admitted with high fever and had neurological disorder; he was diagnosed with atrioesophageal fistula by CT scan. Intraoperative findings showed that the fistula existed adjacent to the left lower pulmonary vein with a vegetation. The esophageal fistula was repaired, and the left atrial fistula was closed. A nasogastric tube tip was placed in the esophagus for decompression and advanced into the stomach for nutritional support. After vomiting, the patient showed loss of consciousness and left hemiplegia. CT scan revealed a micro-air embolism to the brain. The nasogastric tube tip was pulled back into the esophagus. Gastrointestinal fiberscopy showed a pinhole at the fistula, and a percutaneous endoscopic gastrostomy was made. After conservative treatment, the esophageal fistula was closed and mediastinitis was improved. He was discharged with a little neurological deficit.     

Mediastinal recurrence of breast cancer suspecting mediastinal fibrosis

A 63-year-old female, who had undergone a modified radical mastectomy for breast cancer at the age of 45, was suffered from trachyphonia due to left recurrent nerve paralysis at the age of 53. She presented left phrenic nerve paralysis and dysphagia at the age of 61. Computed tomography (CT) revealed mediastinal fibrosis, stenosis of esophagus and superior vena cava, and slight lymph nodes swelling. Video-assisted thoracoscopic mediastinal biopsy was performed and the mediastinal fibrosis was diagnosed as recurrence of breast cancer 17 years after the breast cancer operation. She underwent mediastinal radiation and chemotherapy for mediastinal recurrence and stenting for esophageal stenosis.     

Enucleation of Esophageal Leiomyoma with Azygos Continuation of the Inferior Vena Cava: Report of a Case

We herein report a rare case of esophageal leiomyoma in an 18-year-old woman with azygos continuation of the inferior vena cava. A submucosal tumor was located in the left wall of the esophagus behind the carina. The enlarged azygos vein made video-assisted thoracic surgery so difficult that conversion to a minithoracotomy and transection of the right superior intercostal vein were necessary to fully visualize the tumor. A pathological diagnosis revealed leiomyoma. Our experience suggests that a transection of the right superior intercostal vein is effective for the proper exposure of an esophageal tumor located behind the carina in a patient with an enlarged azygos vein.     

A case with esophageal carcinoma associated with metastatic pulmonary tumor in lung cancer at seven years after the resection of lung cancer

A 69-year-old woman was admitted to our hospital because of dysphasia. The upper G-I examination showed a stenosis at the middle thoracic esophagus and poorly differentiated adenocarcinoma was revealed histologically. Chest CT scan showed a mass shadow in the right upper lobe of the lung. She had undergone a partial resection of right upper lobe because of lung cancer seven years before. She was diagnosed as metachrous double carcinoma of the lung and the esophagus. The method of surgery included right upper lobectomy of the lung, esophagectomy and intrathoracic esophageal reconstruction using the gastric tube. The patient manifested pneumonia due to the failure of the sutures after the surgery and died on the twentieth postoperative day. When conducting simultaneous resection of both cancer and esophageal reconstruction for the double cancer of the lung and the esophagus, it was considered necessary to conduct the anastomosis outside the thoracic cavity for the purpose of preventing the pulmonary complication due to the failure of the sutures.     

A median sternotomy approach for symptomatic right subclavian artery in the adult]

A case of 33-year-old woman with aberrant right subclavian artery was reported. She was admitted to the hospital complaining of progressive dysphagia of six months' duration. The esophagogram revealed an oblique tubular defect in the superior thoracic esophagus. Aortograms confirmed the presence of an anomalous right subclavian artery arising as a fourth branch of the aortic arch, passing behind the esophagus in its course to the right arm. Operation was performed on Sept. 4, 1990. Through a median sternotomy, the ascending aorta and the two carotids were dissected free. With gentle forward retraction of the ascending aorta to the left, the origin of the aberrant right subclavian artery could easily be exposed. The right subclavian artery was then divided and its origin from the distal aortic arch oversewn. The vessel was removed from the retroesophageal position and blood flow reestablished to the right arm by an end-to-side anastomosis to the right carotid artery, using a temporary shunt tube. These procedures were accomplished without difficulty. Postoperatively, the patient made an uneventful recovery and was discharged 16 days after the procedure. A postoperative esophagogram confirmed the removal of the esophageal compression. The blood pressure was equal in the two upper extremities. In follow-up study, her symptoms had completely disappeared.     

Long-term survival case of esophageal carcinosarcoma coexisting with alcoholic liver cirrhosis successfully treated by staged operation: A case report

IntroductionPatients with esophageal cancers including carcinosarcoma sometimes have underlying liver cirrhosis because of a history of heavy drinking. It is definitely required to determine the appropriate surgical strategy and to manage the patients promptly when performing esophagectomy for the esophageal carcinosarcoma coexisting with alcoholic liver cirrhosis.Presentation of caseA 56-year-old male patient with a history of chest pain and difficulty swallowing was admitted to our hospital. He had a history of drinking 250 g of alcohol per day. Endoscopy revealed an irregular protruding tumor on the left wall of the lower-third thoracic esophagus. Computed tomography showed a tumor lesion in the lower-third thoracic esophagus; the images also showed irregularities on the surface of the liver, suggestive of coexisting alcoholic liver cirrhosis. The preoperative diagnosis was T3N2M0, Stage III esophageal leiomyosarcoma. In consideration of the underlying alcoholic liver cirrhosis, a staged operation was planned for this patient as a curative treatment. The patient had an uneventful postoperative clinical course and was discharged on the 47th day after the first surgery. Final histopathological diagnosis was T2N0M0, Stage II esophageal carcinosarcoma. The patient is alive without recurrence three years after surgery.DiscussionThis is the first report of long-term survival case of esophageal carcinosarcoma with alcoholic liver cirrhosis that was treated successfully by staged operation.ConclusionsDespite coexisting with alcoholic liver cirrhosis, staged operation could reduce the surgical invasiveness, so that very good short-term outcome and long-term survival was obtained in the patient with esophageal carcinosarcoma.     

Systemic origin of the sole artery to the basal segments of the left lung without pulmonary sequestration

A sixty-one year-old man with squamous cell carcinoma of the left upper lobe had an aberrant systemic artery to the left basal segments without pulmonary sequestration. Physical examination revealed neither cardiac murmur nor any sign of heart failure, which was at variance with reported cases in the literature. Chest X-ray film showed no abnormal density suggesting sequestrated lung. Bronchogram disclosed obstruction of the left upper lobar bronchus by the tumor and normal segmental bronchi of the lower lobe. Left pulmonary angiogram showed normal arterial distribution of the left upper lobe and the superior segment of the lower lobe, but the basal segmental arteries were not visualized. The aberrant pulmonary artery arising from the descending aorta was visualized by computed tomography. Following dissection of the abnormal vessel pneumonectomy was performed. Pathological examination of the left basal segments revealed prominent atheromatous changes in the aberrant systemic intrapulmonary artery and irreversible obstructive lesions in its tributaries. These arterial lesions in this patient would have precluded plastic operations such as transfer of the origin of the aberrant vessel to the left pulmonary artery even if other circumstances had been favorable for preservation of the left lower lobe.     

Esophageal stricture secondary to Stevens-Johnson syndrome

We report a 7-year-old male with ampicillin-induced Stevens-Johnson syndrome with subsequent extensive skin, conjunctival, oropharyngeal, and laryngeal involvement. Over the next 5 months, he developed complete blindness and dysphagia. A barium swallow revealed absence of both right and left pyriform sinus, and a stricture involving the entire esophagus. Retrograde dilatations, complicated by malignant hyperthermia, have subsequently allowed for the difficult progression from an eight to a 40 French bougie. Eighteen months since the diagnosis of esophageal stricture, he has a normal appearing esophagus and is swallowing without difficulty.     

Functional assessment of the cervical esophagus after gastric transposition and cervical esophagogastrostomy.

OBJECTIVES: The aim of this exploratory study was to investigate swallowing and function of the cervical esophagus after esophageal resection and reconstruction. METHODS: Nine patients (8 males, 1 female; median age 63 years), who underwent esophageal resection for adenocarcinoma, were studied from 6 to 40 months (median 18 months) postoperatively. For all patients, the upper gastrointestinal tract was reconstructed by transposing a narrow gastric tube through the posterior mediastinum to the left neck, where a semi-mechanical anastomosis to the cervical esophagus was performed. No patient had an anatomic obstruction to swallowing or stricture. The oral and pharyngeal phases of deglutition and function of the cervical esophagus were evaluated objectively by video barium swallow, esophagogastroscopy, velopharyngeal examination, manometry and balloon inflation in the cervical esophagus. RESULTS: The median length of the cervical esophagus was 5 cm (range 3-7 cm). Mild reflux laryngopharyngitis was seen in all patients. Although all patients had an objective functional dysphagia measurement (American Speech-Language-Hearing Association) of 7 (normal), five reported subjective dysphagia. Four (of the five symptomatic) patients were found to have high pressure peristalitic activity (mean >100 mmHg) following balloon distention (10-30 ml) of the cervical esophagus, which was painful in three cases. CONCLUSIONS: We conclude that in the absence of an anatomic cause for dysphagia after cervical esophagogastrostomy, a functional etiology may be explained by hypertensive peristalsis resulting from distention of the remaining cervical esophageal remnant. These findings may further explain anecdotal reports of the efficacy of empiric dilation after upper gastrointestinal reconstruction when no stricture is seen.     

Successful treatment of congenital esophageal web by endoscopic electrocauterization and balloon dilatation

We report a 3-year-old boy who presented with a foreign body impacted in the esophagus and had a poor tolerance of solid food since he was 5 to 6 months old. In the last 2 years, he developed progressive dysphagia, anorexia, vomiting, and poor weight gain. An esophagoscopy and barium esophagogram revealed an esophageal web in the distal third of the esophagus. Three courses of endoscopic balloon dilatation resulted in transient improvement in his dysphagia and vomiting; a follow-up barium esophagogram and esophagoscopy showed limited improvement of the esophageal stenosis. Two courses of endoscopic electrocauterization and balloon dilatation improved the clinical symptoms and esophageal stenosis.     

Diffusely infiltrative squamous cell carcinoma of the esophagus presenting diagnostic difficulty: report of a case

We report a rare case of diffusely infiltrative squamous cell carcinoma of the esophagus. The patient, a 68-year-old man, was admitted to our hospital for investigation of dysphagia. Esophagography and upper gastrointestinal endoscopy revealed esophageal stenosis and gastric cancer. As a biopsy from the esophagus revealed no sign of malignancy, he underwent only distal gastrectomy. After 3 months, the stenosis became worse. Again, biopsy from a gastrointestinal endoscopy showed no malignancy, but endobronchial ultrasound-guided transbronchial needle aspiration revealed squamous cell carcinoma of the esophagus. Despite various treatments, the patient died of disease progression 20 months after its onset. Autopsy revealed diffusely infiltrative squamous cell carcinoma of the esophagus, which is a rare malignancy with few case reports documented.     

A case of corrosive esophagitis with stenosis

A 41-year-old man was admitted to our hospital because of pharyngeal pain and vomiting after intentionally swallowing sodium hydroxide. Gradually esophageal stenosis took place. After 9 months from the taking poison the patient was operated. We tried blunt dissection of esophagus. But the procedure failed in because the wire of stripper was cut. So performed total esophageal resection under the right thoracotomy. The right side colon was used to re-construction through antero-sternal space that was anastmosed to cervical esophagus and stomach. The postoperative course was uneventful.     

An anomalous segmental vein of the left upper lobe of the lung: preoperative identification by three-dimensional computed tomography pulmonary angiography

A number of variations in the pulmonary arteries and veins have been documented, and the information is very important for performing a safe lung resection. This report describes a case of an anomalous segmental vein of the left upper lobe of the lung. The patient was a 75-year old male who was suspected to have lung cancer in the left upper lobe. A contrast-enhanced computed tomography showed a vessel behind the left lower bronchus. A three-dimensional computed tomography angiography demonstrated that it was an anomalous vein for the apicoposterior segment of the left upper lobe of the lung, draining into the left inferior pulmonary vein. The aberrant vein was readily identified during surgery and was divided without injury, and a left upper lobectomy was successfully performed. Aberrant pulmonary veins for the superior segment of the right upper lobe of the lung are rarely observed, and the same kind of anomaly on the left side has not been reported.     

Transhepatic transportal embolization of gastroesophageal veins in profuse esophageal hemorrhage

The article deals with the results of treatment of 27 patients with profuse esophageal hemorrhage in portal hypertension. Sixteen patients were treated by roentgen-guided endovascular surgery, namely, transhepatic transportal embolization of varicose veins of the esophagus and stomach. In view of the peculiarities of blood drainage and for the prevention of recurrent bleeding, seven patients were subjected to additional manipulations: embolization of the splenic artery (4) and the left gastric artery (3). Despite reliable arrest of bleeding, 3 patients died in the first 2-3 days from progressive hepatorenal failure. Only one patient had recurrent bleeding in the late-term period. The authors believe transhepatic transportal embolization of the gastroesophageal veins at the peak of hemorrhage to be a hardly injurious and effective method for its arrest.     

Results of Collis gastroplasty and selective fundoplication, using a left thoracoabdominal approach, for failed antireflux surgery.

OBJECTIVE: To study patterns of failure following primary antireflux surgery and to evaluate efficacy of reoperation using a left thoracoabdominal Collis gastroplasty and selective fundoplication. METHODS: Thirty-one patients who underwent reoperative antireflux surgery between 1991 and 2000 were studied. Transabdominal fundoplication had been performed in 21 patients, and ten patients had a partial fundoplication by left thoracotomy, 1-33 years (mean, 15 years) previously. All patients presented with clinically disabling symptoms. Objective studies documented for all patients, a disrupted fundoplication, a short esophagus, and an associated hiatus hernia (Type I: 21 patients, 68%; Type III: ten patients, 32%), esophagitis (nine patients, 29%), and Barrett's mucosa (five patients, 16%). Abnormal esophageal motility was found in nine of 26 (36%) patients studied. All patients were reoperated using a left thoracoabdominal approach, with epidural analgesia. A Collis gastroplasty was used to lengthen the esophagus, incorporating a complete (24 patients, 77%) or partial (seven patients, 23%) fundoplication based of preoperative esophageal function studies. RESULTS: There was no perioperative mortality. Median length of hospitalization was 8 days, and was uncomplicated for 18 (58%) patients. Postoperative morbidity was considered minimal, and comprised left lower lobe infiltrates (six patients, 19%), atrial fibrillation (three patients, 10%), urinary tract infection (one patient, 3%), superficial wound infection (one patient, 3%), aspiration (one patient, 3%), and nausea (one patient, 3%). Median follow-up was 42 months (6-105 months), and was complete for 29 patients. Six patients (21%) had moderate-severe post-thoracotomy pain, for up to 18 months postoperatively, and five patients (17%) required esophageal dilation, ranging from two to six dilations within the first 6 months after surgery. Overall, 93% (27/29) of patients were satisfied with the results of surgery, in terms of quality of swallowing and control of preoperative symptoms. CONCLUSIONS: In this series, failure of primary antireflux surgery was related to short esophagus. Intermediate-term subjective results of reoperative antireflux surgery were good for selected patients who undergo esophageal lengthening and fundoplication. The left thoracoabdominal approach was safe, generally well tolerated, and provided excellent exposure of the esophagogastric junction for complex reoperative antireflux surgery.     

A thoracic aortic aneurysm with respiratory failure caused by the mechanisms of stenosis of the left bronchus and ipsilateral pulmonary artery--report of a case and review of the literature

Clinical symptoms of thoracic aortic aneurysm vary widely from symptoms resulting from its rupture to those due to compression of surrounding organs. Furthermore, the onset of symptoms is frequently followed by a fatal outcome unless emergency measures are taken. We have recently experienced a patient who developed respiratory insufficiency caused by an aneurysm of the descending thoracic aorta compressing the left primary bronchus and the right pulmonary artery, the former causing ventilatory failure in the left lung and the latter interfering with blood flow in the right lung. The patient underwent emergency prosthetic graft replacement and showed temporary symptom improvement. However, a postoperative complication of esophageal perforation due to ischemic necrosis occurred and eventually caused acute empyema followed by death. The patient was a 48-year-old male who presented with symptoms similar to bronchial asthma. Angiographic examination (iv-DSA) revealed compression of right pulmonary artery by an aneurysm of the descending thoracic aorta. Bronchoscopic findings included extramural stenosis of the left bronchus accompanied by arterial pulsation. As an emergency measure, artificial blood vessel replacement of the descending thoracic aorta was performed. However, the patient developed postoperative acute empyema and died on the 19th postoperative day. Autopsy revealed ischemic necrosis on the esophageal wall where the aneurysmal lesion had touched before operation. This seems to have formed a perforation into the left thoracic cavity and ultimately to have caused acute empyema. Since we believe that the pathogenesis and clinical course observed in this patient is rather rare, the case is reported in accompanied by relevant data from the literature.     

Congenital esophagobronchial fistula treated with thoracoscopic assisted surgery

A case of congenital esophagobronchial fistula in a 58-year-old woman was described. The patient had presented with repeated attacks of pulmonary infection from her childhood and had a history of recurrent cough after eating or drinking. Preoperative examinations including esophagogram by barium swallow revealed existence of a fistula between the upper thoracic esophagus and the right B3 bronchus. The fistula was recognized as type I of Braimbridge classification. Thoracoscopic assisted fistulectomy and diverticulectomy for esophagobronchial fistula with esophageal diverticulum were performed. The neck of the diverticulum and the fistula were divided with endo-stapling technique. Intraoperative esophagoscopy was found to be useful for the definite localization and complete excision of the fistula and the diverticulum and the avoidance of stenosis of the esophagus. Postoperative course was uneventful. It is to be considered that the present thoracoscopic assisted procedure with intraoperative esophagoscopy can be used as a standard operative procedure for esophagobronchial fistula with esophageal diverticulum.     

A case report of successful mitral valve replacement for congenital mitral stenosis associated with coarctation of the aorta and ventricular septal defect

A 5-month-old infant with coarctation of the aorta, ventricular septal defect and mitral stenosis known as "Shone's anomaly" is presented. He underwent the repair of coarctation of the aorta by means of the extended aortic arch anastomosis and banding of the pulmonary trunk at 1 month of age and the patch closure of ventricular septal defect and debanding of the pulmonary trunk at 3 months of age in our institution. About 2 months after second surgery, he had been admitted to our institution due to developing tachypnea and he needed the support of mechanical ventilation. The chest X-ray showed pulmonary congestion and the echocardiography revealed only one papillary muscle of mitral valve and pressure gradient about 30 mmHg through mitral valve. Mitral stenosis due to parachute mitral valve was suspected and he was subjected to an emergent surgery. Initially we performed mitral valve repair for parachute mitral valve but echocardiography during the surgery revealed moderate grade of mitral regurgitation and a hemodynamics was not satisfactory. Eventually mitral valve replacement was successfully done with Carbo-Medics mechanical valve (19 mm in diameter) in the position of left atrial wall because his mitral annulus was so small as 10 mm in diameter. The postoperative course was uneventful and the patient has been doing well.     

Repair of tetralogy of Fallot in an adult; the importance of preoperative examination for major aorto-pulmonary collateral arteries

We report the repair of tetralogy of Fallot in a 51-year-old man. He underwent a left classical Blalock-Taussig (B-T) shunt when he was ten years old. Preoperative angiography showed a patent B-T shunt. Total corrective surgery was performed. Postoperatively, he suffered from left ventricular failure. Re-intubation was required three times. Postoperative catheterization showed excellent correction of the right ventricular system, however, descending aortography revealed a great many aorto-pulmonary collateral arteries, which caused the left ventricular failure. Coil embolization of these 13 collateral arteries was performed and he recovered from the left ventricular failure. We conclude that even in an elderly patient with tetralogy of Fallot, total correction should be performed, since the surgical risk is acceptable and the procedure improves the capacity for physical activity and quality of life. Preoperative examination of collateral arteries is important, especially in elderly patients, and coil embolization should be considered.
