1/13. Esophagogastric fistula secondary to teflon pledget: a rare complication following laparoscopic fundoplication.Laparoscopic fundoplication has become the standard operation for gastroesophageal reflux disease. In our service, a laparoscopic fundoplication is performed as a 2-cm floppy 360 degrees wrap with division of the short gastric vessels and the fundoplication is sutured using a prolene 2/0 mattress suture (Ethicon, USA) and buttressed laterally with two teflon pledgets (PTFE 1.85 mm; low porosity, Bard, USA). We report a patient with post-operative dysphagia due to an esophagogastric fistula caused by erosion of a teflon pledget. This is the first such case in 734 laparoscopic fundoplications performed between January 1991 and December 1998. reoperation was required, resulting in a prolonged convalescence. A review of current literature has not revealed any similar cases. Causes for this rare complication are postulated.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/13. Aortoesophageal fistula associated with tuberculous mediastinitis, mimicking esophageal Dieulafoy's disease.Aortoesophageal fistula is a rare and lethal disorder that may result from primary diseases of aorta or esophagus, aortic bypass graft, ingestion of foreign body, trauma, surgical procedure or instrumentation. Tuberculous fistula is extremely rare. We present a 27-yr-old female patient with aortoesophageal fistula associated with tuberculous mediastinitis. The patient experienced massive hematemesis and esophagoscopy revealed a small mucosal defect with exudate-coated blood vessel like Dieulafoy 's lesion on about 25 cm from the incisor teeth. Despite two sessions of endoscopic hemostatic procedures, active massive hemorrhage recurred and was controlled effectively with a prompt insertion of Sengstaken-Blakemore tube. The patient underwent open thoracotomy, which revealed aortoesophageal fistula. Numerous white-yellowish, millet seed-like tubercles were scattered in pleural and abdominal cavity. Division of fistular tract and esophageal resection with Ivor-Lewis anastomosis were performed. Histopathologic study confirmed tuberculous pleuritis and peritonitis. The patient died of postoperative pulmonary complication.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/13. radiation-induced aortoesophageal fistula: an unusual case of massive upper gastrointestinal bleeding.Aortoesophageal fistula (AEF) is an unusual cause of massive upper gastrointestinal bleeding. Thoracic aortic aneurysm is the most common etiology of primary AEF followed by, respectively, foreign body ingestion, esophageal malignancy, and postsurgical fistulization. radiation-induced damage to the great vessels is well recognized and some authors in the past have suggested that AEF may be caused by radiotherapy. However, previous case reports of radiation-induced AEF involved patients who received radiotherapy for esophageal carcinoma, and precise histopathologic differentiation between AEF secondary to esophageal malignancy and that induced by radiation was difficult. We present here the unique case of a patient with a non-esophageal carcinoma who received radiotherapy before the development of an AEF, thus providing further evidence for the role of radiation injury in the development of this condition. As well, we discuss current opinion regarding etiology, clinical presentation, diagnosis, and management of this entity.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/13. exsanguination by subclavian-esophageal fistula associated with a left subclavian aneurysm.Aortic aneurysms are a common autopsy finding, but aneurysms confined exclusively to the subclavian arteries are rare. When found, they are typically associated with trauma, surgery, or aberrant vessel distribution. Subclavian-esophageal fistula formation is also rare, with the vast majority being related to aberrant vessel distribution or esophageal foreign bodies. Dicle et al. first reported a subclavian-esophageal fistula associated with a non-aberrant subclavian artery aneurysm in 1999 (1). The following case would mark the second report of that phenomenon, and the first in the setting of a forensic autopsy.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/13. Importance of additional microvascular anastomosis in esophageal reconstruction after salvage esophagectomy.Esophageal reconstruction after salvage esophagectomy in patients who have undergone curative-intent chemoradiotherapy for esophageal cancer is associated with a significant risk of perioperative morbidity and mortality. In particular, anastomotic leakage can cause severe and potentially fatal complications, including mediastinitis and pneumonia. The authors performed esophageal reconstruction with a pedicled right colon graft after salvage esophagectomy in eight patients. To decrease the rate of anastomotic leakage, the authors performed an additional microvascular anastomosis at the distal end of the graft. The distal stumps of the ileocolic artery and vein were anastomosed to the cervical vessels. After surgery, aspiration pneumonia and localized wound infection were observed in two patients each, but slight anastomotic leakage was observed in only one patient. Postoperative swallowing function was satisfactory in all patients. Although the incidence of anastomotic leakage is reportedly high, the authors observed anastomotic leakage in only one of eight patients. The authors believe that additional microvascular anastomosis helps prevent anastomotic leakage, especially in patients who have undergone salvage esophagectomy after curative chemoradiotherapy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/13. Complete coverage of in situ aortograft by total omental pedicle flap as the most reliable treatment of aortoesophageal fistula.Aortoesophageal fistula secondary to a thoracic aortic aneurysm is usually a fatal disease with few survivors reported previously. We encountered 2 consecutive patients who were treated successfully with esophagectomy and in situ aorta reconstruction using cryopreserved homograft that was wrapped completely with omental pedicle flap. For the construction of omental flap, the right gastroepiploic artery was resected at the root and all the vessels entering the greater curvature and the transverse colon were resected at the adherent edges. Because the gastroepiploic arcade is totally preserved, large amounts of omental tissue could be obtained, with an excellent blood supply mainly from the left gastroepiploic artery. This type of omental flap is highly mobile, easily transferred to the left hemithorax, and has enough volume to cover the in situ aortic graft completely including anastomosis lines. Thus, our omental coverage appears to be the most reliable method to prevent postoperative graft infection.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/13. Fatal aortoesophageal fistula due to double aortic arch: an unusual complication of prolonged nasogastric intubation.Fatal hematemesis occurred in a 3-month-old boy due to erosion by a nasogastric tube into the right component of an unrecognized double aortic arch. This is the youngest of six reported patients with arterioesophageal fistula in the literature. Including this patient, five of six had nasogastric tubes in place. The tube may have led to fistula formation by compression of the esophageal wall against an anomalous vessel. When a vascular ring is suspected, indwelling esophageal tubes such as nasogastric tubes should not be used.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/13. Pulmonary sequestration with congenital broncho-oesophageal fistula.Complaints of older patients due to a congenital broncho-pulmonary foregut malformation are rare. A 53 yr old woman presented with this condition. The diagnosis was made by means of oesophagography, which showed a broncho-oesophageal fistula. Using the supplying vessel, identified by angiography, as a guideline, an operation was carried out to correct the anomaly.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/13. Sudden death from perforation of a benign oesophageal ulcer into a major blood vessel.Two cases of sudden death due to perforation of a benign oesophageal ulcer into a major blood vessel are reported. In one man, anaemia and aspiration pneumonitis dominated the clinical picture. He had an oesophageal stricture and a chronic peptic ulcer associated with an incarcerated hiatus hernia. death was due to haemorrhage caused by perforation of the ulcer into the thoracic aorta. The second patient presented with confusion and falls, backache and indigestion. She had a hiatus hernia and a large benign chronic oesophageal ulcer. death was due to perforation of the ulcer into the left pulmonary vein. The cases are presented for their rarity, to illustrate the complex and late presentation of problems in geriatric medicine, and as a reminder that reflux oesophagitis can be dangerous.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
10/13. Cerebral arterial air embolism due to an esophago-atrial fistula seen on CT.A case of cerebral air embolism from a rather unusual cause is reported; an esophago-cardiac fistula permitted food particles and air to enter the systemic arterial circulation. Massive embolization caused the patient to become deeply comatose rather suddenly. The computed tomogram (CT) revealed massive cerebral edema with the contradictory finding of wide superficial subarachnoid spaces. These subarachnoid spaces on further evaluation proved to be air in the cerebral vessels.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
