1,597 cases of operation on the cardiovascular disease were performed at the Hanyang University Hospital from 1972 to 1987. Of these, 1,005 cases were open heart surgery. It was started from July 1975. Among the open heart cases, 725 were congenital heart diseases and 280 were acquired heart diseases. In congenital heart cases, 554 were acyanotic and 171 were cyanotic. The operative results were as follows; the overall mortality of cardiovascular surgery was 7.1%, the open heart mortality was 9.5%. This analyses were reported in memory of the achievement of 1,000 cases of open heart surgery.

From May 1977 to November 1993, 1, 500 cases of open heart surgery were performed under the cardiopulmonary bypass. In 1500 cases of open heart surgery 975 cases[65%] were congenital heart disease and 525 cases[35%] were acquired heart disease. In 975 cases of congenital heart disease, there were 812 cases[83%] of acyanotic congenital heart anomaly and 163 cases of cyanotic congenital anomaly. In 525 cases of acquired heart disease, most cases were valvular heart disease in which 557 valves were implanted. The each operative mortality of congenital and acquired disease was 7.7% and 7.4% respectively and then overall mortality rate was 7.6%. There has been increasing incidence of open heart surgery in infants in recent years. After 1990, 28 cases of infant open heart surgery below the 12month were performed. Most lowest weight was 2, 200g[15 days]. Operative mortality of open heart surgery in infant with weight below the 10kg was very high as a 25.7%.

Most patients with temporomandibular disorder can be treated conservatively. However, open TMJ surgery can be needed in some patients. We analysed the patients with TMD which open surgery has performed since 1998. Open surgery was carried out in 8 patients. Age ranged from 22 to 61 years, with a mean of 42.8years. All patients were male. Final diagnosis was obtained based upon clinical, radiographic and operative finding as follows; habitual luxation, bony ankylosis, traumatic arthritis, disc displacement with destructive change, disc displacement and adhesion. Etiologic factors included trauma(4), infection(2), and unknown(2). Open surgery included arthroplasty with either of condylectomy, eminectomy, meniscoplasty, capsurrohaphy. All patients were recovered uneventfully without severe complications. Some mouth opening limitation and mouth opening deviation remained. Postoperative aggressive physical therapy and careful follow up were performed. In conclusion, open TMJ surgery must be considered in organic disease such as ankylosis, tumor and TMD without favorable recovery after long-term conservative therapy.

Objective : The objective of this study is to evaluate and compare the clinical results between classical open surgery and percutaneous endoscopic lumbar discectomy[PELD] in cases of extraforaminal lumbar disc herniation. Methods : We obtained the clinical data from 47 patients with extraforaminal lumbar disc herniations who underwent the open paramedian muscle-splitting approach or percutaneous endoscopic lumbar discectomy[PELD] between January 2001 and February 2004. This study consisted of patients with soft disc extraforaminal herniations. The patients were assessed with the visual analogue scale[VAS] and MacNab's criteria before surgery, just before discharge, and postoperative 1 year. Results : There were 25 cases in the open surgery group and 22 cases in the PELD group. The average operating time was $78{\pm}36.71\;min$ in the PELD group and $110{\pm}29.68\;min$ in the open surgery group. The mean hospital stay was $2.73{\pm}2.62$ days in the PELD group and $7.68{\pm}2.59$ days in the open surgery group. VAS decreased from $8.34{\pm}0.66$ to $1.29{\pm}2.27$ in the PELD group and from $8.40{\pm}1.40$ to $1.70{\pm}1.72$ in the open surgery group at the one-year follow-up. The success rate of PELD was 86.4%, compared with 80.0% for open surgery. However, there were no statistically significant difference between two groups for success rate and VAS. Conclusion : Although the success rates were similar in both groups, PELD is less invasive, faster, and safe procedure than open surgery for extraforaminal disc herniation in selected patients.

The aim of this study was to compare peritoneal dialysis catheter insertion by the open method to the laparoscopic method. Twenty four laparoscopic and 10 open peritoneal dialysis catheter placements were performed in children between 2001 and 2008. Patient characteristics, operation related data, procedural complications and clinical outcome were compared. Although there were no cases of catheter obstruction, exit site infection or bleeding in the laparoscopic group, compared to the open method, there was no statistically significant difference between the two groups. Catheter removal rate due to complication was high in the open group and catheter survival rate was high in the laparoscopic group. We concluded that laparoscopic peritoneal dialysis catheter placement is feasible in children of all age groups with at least equivalent functional results compared to the open method. An advantage of laparoscopic catheter insertion is removal of the great omentum and easy fixation of the catheter to the abdominal wall.

Delayed cardiac tamponade in an uncommon and frequently fatal complication after open-heart surgery. We had been experienced two cases of delayed cardiac tamponade as a complication of open-heart surgery and treated successfully by reinsertion of pericardial drain through subxiphoid route. First case was 60 years old female patient and underwent MVR under impression of MSi + Ti Second case was 19 years old male patient and underwent total correction of T.O.F.with Blalock shunt [Lt]. Both cases had Initial symptoms, which were epigastric pain, chest tightness, dropped blood pressure, and increased pulse rate and respiratory rate, mimic as low cardiac output syndrome after open-heart surgery. Roentgenogram of the chest showed a rapid increased cardiothoracic ratio. It is important to realize the presence of late cardiac tamponade for proper diagnosis of complication after open-heart surgery.

Purpose : We evaluated clinical result of arthroscopic and open Bankart repair in anterior shoulder instability to identify factors iuluencing operative result and prognosis. Materials & Methods . We reviewed 24 patients of anterior shoulder instability treated with arthroscopic Bankart repair in 16 cases and open Bankart repair in 8 cases. Average age was 26 years old and involved in dominant arm in 15 cases. Patients were suffered instability for 3.1 years before operation and mean follow-up was 2 year 9 months ( 1 you 9 months -4year 10 months). Results : Post operative pain was subsided in 2 weeks in arthroscopic surgery and 3 weeks in open surgery. The final range of motion after arthroscopic repair were flekion in 168" , external rotation in 54" , and internal rotation in 79, and after open repair 168" ,49" , and 78 respectively. In arthroscopic surgery,2 cases (13%) were redislocated, and 4 cases(25%) showed mild instability. In open case,1 case (11%) showed mild instability. According to function- al result by Rowe grading scale, satisfactory results were 12case (76%) in arthroscopic repair and 7 cases (88%) in open cases. Conclusions Both arthroscopic or open Bankart could get good results in the treatment of anterior instability of shoulder. In arthroscopic repair, perioperative morbidity was lower than open repair, but it needs careful rehabilitation program to prevent redislocation and to return to sports activity.

Six hundred and twenty two cases of open heart surgery were performed at Sejong General Hospital in 1986. And also, 117 cases of non open heart cardiac surgery had been performed during same period. Among the 622 open heart cases, 548 were congenital cardiac diseases and 74 were acquired heart diseases. In congenital heart patients, 422 were acyanotic and 126 were cyanotic. There were 52 cases of infant open heart Surgery below 12 months. Acyanotic group were consisted of 314 VSD, 66 ASD, 13 AVSD, 9 PDA, 8 ASD + PS, 4 AS, and 8 other rare cardiac cases. And cyanotic group were consisted of 84 TOF, 15 DORV, 5 Trilogy, 4 Ebstein`s anomaly, 3 PS + TR, 3 TGA, 3 TAPVR, 3 Pulmonary atresia and 6 other rare cardiac diseases. Majority of the acquired heart cases were valvular heart diseases. And there were also 4 cardiac myxoma and one endomyocardial fibrosis in acquired heart disease group. The operative results were as follows: Overall operative mortality, 5.3%: acyanotic 2.4%: cyanotic 15.8% and acquired heart disease, 8.5%.

One hundred cases of open heart surgery were done at this Department in 1977. There were 65 congenital anomaly and 35 acquired diseases. Out of 65 cases of congenital malformation 35 acyanotic and 30 cyanotic cases were found. Fifteen cases of ventricular septal defect and 29 tetralogy of Fallot were noted eight patients expired out of 65 congenital anomaly [12.3%] , 4 out of 35 acyanotic [11. 4%] and 4 among 30 cyanotic anomaly[13.3%]. Among 35 cases of acquired heart disease 3 atrial myxoma [2 left and one right] and 32 valvular lesions were noted. In two cases open mitral commissurotomy, and in 30 valve replacement were done. Twenty-two single valve and 8 double valve replacement were done. Seven patients expired out of 30 patients [23.3%]. Among 22 single valve replacement cases 2 and among 8 double valve 5 died. ~ In eighteen mitral valve replacement cases 2 deaths occurred. One mitral insufficiency patient who expired suffered from severe pulmonary` hypertension [PA=120/67mmHg], tricuspid insufficiency and a large ventricular septal defect. The patient underwent mitral valve replacement, tricuspid annuloplasty and patch closure of ventricular septal defect. Over all mortality rate for 100 open heart surgery cases was 15%. Since 1977 open heart surgery cases were done routinely in this institution and cases are increasing rapidly. With present rapid improvement of economical status and introduction of medical insurance system, open heart surgery will be firmly established in Korea in the very near future.
