Bilateral traumatic rupture of diaphragm is very rare. One case due to car accident is reported. Preoperative chest X-ray revealed the diaphragm rupture in the left side and the hemothorax in the right side. During the completion of left diaphragm repair through left thoracoabdominal incision, right diaphragm rupture was found incidentally. Left diaphragm was repaired using pledgets which were anchored at the thoracic wall. Right diaphragm was also repaired by interrupted Halsted sutures through seperated right thoracotomy. Postoperative course was uneventful.

With the increasing performance of open heart surgery during recent years, the occurrence of renal failure associated with cardiopulmonary aypass has received considerable attention. This patient was 33 yaar old woman who undertaken mitral valve replacement under the cardiopulmonary bypass. Acute renal failure developed after 2nd postoperative day. So we report here the course of renal failure as it occur in immediate relation to open heart surgery and examine the role of preoperative, intraoperative and postoderative factors.

From December 1981 to June 1987, thirty one patients suffering from low output syndrome after cardiac operation received cardiac assist with intraaortic balloon pump. Fifteen patients survived [survival rate 48.4%]. After receiving assist with IABP, urine output increased, heart rate and central venous pressure decreased, reflecting improved myocardial performance. Poor preoperative hemodynamic and functional status resulted in poor survival despite of assist with IABP. Poor pre-IABP hemodynamic status also resulted in high mortality after assist with IABP. Our experience suggests that IABP should be introduced early in the course of worsening to get good result.

30 case of achalasia treated by modified Heller`s myotomy at the department of thoracic surgery of Seoul National University Hospital from 1965 to 1987 were analyzed. Preoperative Symptoms were alleviated completely or partially in 90% of the 30 patients who were available for follow up study [average: 3.6 years]. Excellent or good results were achieved in 83.3% of patients. Only two of the poor results were due to reflux esophagitis. It is concluded that an antireflux procedure is not routinely necessary to prevent postoperative reflux esophagitis if the technique of espohagomyotomy is used properly.

We report a case of subglottic stenosis by blunt neck trauma. Preoperative CT showed a stenosis extending distally from just below the vocal cords for 4cm. Concomittent bilateral vocal cords paralysis and quadriplegia were present. At operation the lesion was severely adhesed and the lumen was nearly obstructed. The recurrent laryngeal nerves were embedded in fibrous tissue and were not identified at ease. The stenosed segment was resected and direct end-to-end anastomosis with preservation of the recurrent laryngeal nerves was performed. Six months latar he discharged with intermediate position of vocal cord paralysis.

Cavernous angiomas of the cranial nerves are rarely reported. We report a case of a 33-year-old man affected by a cavernous angioma originated in the oculomotor nerve with it's palsy. Preoperative radiological findings are difficult to differentiate it from meningioma or neurinoma. Postopertive pathological report discloses it as cavernous angioma. We discuss radiological, pathological features and management of this vascular lesion of the cranial nerve.

Pharyngoesophageal diverticulum is a well-known disease entity but is seldomly reported in Korean literature. Recently the authors experienced two cases of pharyngoesophageal diverticulum. A 46 year old female and a 51 year old female patients were admitted due to foreign body sensation in esophagus and dysphagia. Preoperative esophagography and esophagoscopy confirmed the diagnosis of pharyngoesophageal diverticulum in each patient. The authors performed one-stage pharyngoesophageal diverticulectomy and myotomy. Postoperative esophagography revealed no diverticulum or stenosis and symptoms were markedly relieved.

Bochdalek hernia is the congenital posterolateral defect in the diaphragm caused by a failure of the pleuroperitoneal canal to close at 8 weeks, gestation. Infants with hernia diagnosed at birth have poor prognosis. Survival rate depends on pulmonary growth and development, preoperative stability and postoperative care. We experienced two cases of Bochdalek hernia, one in right was repaired with patch closure using sheet and the other in left was repaired with simple closure.

Nowadays, the incidence of nasal bone fracture is increasing because of social complexity with frequent social activity, and reduction of fractures is relatively simple and can be corrected in short operation time. However, the postoperative results are known to be less satisfied with higher complication rates relatively. These problems could have resulted from inaccurate recognition and interpretation of fracture aspect, inaccurate planning of operation resulting in under or overcorrection, ignoring septal management, complication related nasal packings with removal, postoperative management, and patient satisfaction with complication.

Sometimes, there are conditions when rapid control of the hypertension needed such as malignant hypertension, and the preoperative pereparation of the hypertensive patient requiring emergency operation, etc. Using the adaptive control algorithm, the mean arterial pressure reduction is achived rapidly and safely in hypertensive rabbit. Among the adaptive control algorithms the pole assignment self tuning control algorithm is superial to the one step ahead minium variance control algorithm. The convergence time is less than 600 sec, and the standard deviation of experimental data are less than 4 mmHg.
