1/580. Venous gas embolism during endoscopy.

    Venous gas embolism is a rare but serious complication of laparoscopic and endoscopic procedures. We describe the case of a 33-year-old woman with a strictured hepaticojejunostomy anastomosis who was treated with transabdominal endoscopic balloon dilation. During the procedure, she suffered a venous gas embolus with immediate cardiovascular collapse. After treatment with pressors, electrical cardioversion, and multiple aspirations of the right ventricle, the patient recovered fully. We reviewed all reported cases of venous gas embolism during endoscopy over the past 30 years and identified multiple risk factors. We suggest precautions to minimize future complications in patients at increased risk.

2/580. superior sagittal sinus obstruction and tuberculous abscess.

    Intracranial tumours such as meningiomas may occasionally produce raised intracranial pressure by occluding a venous sinus. More uncommonly, midline tumours in the occipital regions of the skull can produce elevated intracranial pressure by non-thrombotic compression of the superior sagittal sinus. We present a case of raised intracranial pressure secondary to non-thrombotic obstruction of the superior sagittal sinus by a midline tuberculous abscess.

3/580. Superior mesenteric artery (Wilkie's) syndrome: report of three cases and review of the literature.

    Of the three cases of superior mesenteric artery (Wilkie's) syndrome presented, one was associated with anorexia nervosa; this association has not been reported before. Two patients were treated surgically with a duodenojejunostomy, and one was treated medically. Vascular compression of the duodenum is a controversial subject. The syndrome probably is more common than generally recognized and is underdiagnosed due to its exclusion from the differential diagnosis of small-bowel obstruction. Its recognition is important because early diagnosis of a partial obstruction may allow for medical rather than surgical intervention, as exemplified by our third case.

4/580. Bilateral ophthalmoplegia and exophthalmos complicating central hemodialysis catheter placement.

    We describe a 58-year-old woman who presented with bilateral ophthalmoplegia, exophthalmos, and headache and was found to have retrograde internal jugular vein flow secondary to a high-grade obstruction of the ipsilateral brachiocephalic vein from a previous hemodialysis catheter placement. The patient had also a high-flow dialysis graft in the ipsilateral arm. The cranial and extracranial venous system congestion resolved, and the signs disappeared soon after a balloon angioplasty and stent placement at the level of the obstruction.

5/580. Helical computed tomographic minimum-intensity projection of a slit in an airway obstruction.

    We treated a 54-year-old man with an anastomotic obstruction after a right upper sleeve lobectomy. By using minimum intensity projection images that were generated from helical computed tomographic data sets that indicated a twisted slit enhanced with air a few millimeters in length, through anastomosis to the distal bronchus, we successfully treated the obstruction by bronchoscopic balloon dilatation.

6/580. Post-Mustard procedure pulmonary venous obstruction: An opportunity for anatomic correction with a one-stage arterial switch.

    A 14-year-old boy after a Mustard procedure for transposition of the great arteries developed pulmonary hypertension secondary to baffle obstruction. This occurred over several years without apparent significant symptomatology. Systemic-level pressure prevailed in the left (pulmonary) ventricle and provided an opportunity to perform a successful one-stage arterial switch.

7/580. Botulinum toxin: adjunctive treatment for posterior glottic synechiae.

    INTRODUCTION: Synechiae formation of the posterior glottis can result in tracheostomy dependence secondary to airway obstruction. Stenosis is caused by total or partial fixation of the vocal folds in adduction resulting from scar contracture. The treatment poses a management dilemma because of recurrent scar formation, made worse by mobility of the vocal folds. Although various treatment options from conservative endoscopic repair to open procedures have been proposed, the results are not satisfactory and patients often require multiple procedures. methods: We present the trial of a conservative approach that includes microscopic CO2 laser resection of the scar with concomitant botulinum toxin injection of the interarytenoid and thyroarytenoid muscles of the more mobile cord. This results in a temporary paresis of the adductor muscles and hence prevents overadduction in the posterior commissure during the postoperative healing period. STUDY DESIGN: We present the surgical technique and results in three patients who underwent the procedure. RESULTS: Treatment in all three patients was successful. CONCLUSIONS: The appropriate use of botulinum toxin may help improve the treatment outcome of posterior synechiae of the larynx without sacrificing any laryngeal components.

8/580. Posttraumatic intestinal stenosis presenting as a perforation: report of a case.

    A 78-year-old woman was admitted to the hospital after falling into a ditch approximately 1 m deep and sustaining a blunt abdominal trauma with a left femur fracture. On the tenth day after admission, symptoms of a small bowel obstruction occurred. A nasogastric tube was inserted, and the symptoms thus improved. She sometimes complained of abdominal pain during the 12 months after the fall, but recovered with conservative management. The next year, she was readmitted to the hospital for a pin extraction of the left femur bone. During this admission, 15 months since her admission after her fall, she again complained of abdominal pain. abdominal pain increased with a muscular defense, and abdominal x-rays revealed free air. She was referred to our hospital with a diagnosis of perforative peritonitis, and emergency surgery was performed. Upon laparotomy, circumferential stenoses of the small bowel were recognized in the proximal segments about 40cm, 80cm, and 100cm from the ileocecal region. In addition, a perforation and prominent dilatation of the bowel segment was observed just proximal to the stenosis about 100cm from the ileocecal region. She underwent a small intestinal resection at two sites. There were no findings of an intestinal specific ulcer, such as Crohn's disease, intestinal tuberculosis, or malignancy, based on the results of a histopathological examination.

9/580. radiation-induced bronchial stenosis: a new cause of platypnea-orthodeoxia.

    Platypnea-orthodeoxia is encountered in a variety of cardiac, pulmonary, and hepatic disorders. We report its occurrence in a 59-year-old man who had had combined external-beam and high dose-rate iridium brachytherapy for a stage I non-small-cell carcinoma of the right upper lobe 2 years earlier. The post-radiation course was complicated by a severe radiation bronchitis; the onset of platypnea-orthodeoxia signalled the development of severe bronchial stenosis that was transiently relieved, initially by dilatation, and later by stent placement, though the patient ultimately died of a pulmonary hemorrhage. The dosage of brachytherapy given, the combined external-beam therapy, and the long survival after completion of radiation therapy were likely factors in the development of bronchial stenosis. We discuss the tomographic and bronchoscopic features of radiation-induced bronchial stenosis.

10/580. A case of incomplete Currarino triad with malignant transformation.

    A case of an incomplete Currarino triad is reported. The baby underwent an emergency laparotomy due to a life-threatening intestinal obstruction caused by severe rectal stenosis. During the posterosagittal anorectoplasty (PSARP), a presacral teratoma was identified and resected. The tumor recurred three times; she initially responded to chemotherapy, but nonetheless died at the age of 4 years. In cases with evidence of anorectal stenosis, a presacral mass should be suspected. PSARP is the best choice of treatment for both the anorectal anomaly and excision of the presacral mass. The presacral region should be followed up closely for recurrence of the tumor.
