BACKGROUND: To evaluate the influence of changes in mitral valve area (MVA) and left atrial pressure on pulmonary vein flow (PVF) we analyzed PVF with transesophageal echocardiography (TEE) before, after and one-year after percutaneous mitral valvuloplasty (PMV) in patients with mitral stenosis (MS) in sinus rhythm. METHODS: PMV was guided with TEE. Follow-up TEE was done about one year after PMV. MVA and transmitral mean gradient (TMG) were measured. Systolic velocity (S), diastolic velocity (D), atrial reversal velocity (AR), their time-velocity integral (S-TVI, D-TVI, AR-TVI) and their ratio (S/D ratio, S-TVI/D-TVI ratio were evaluated. RESULTS: The number of patients was twenty-two (F:20). The age was 39+/-9 years (range:26-64). Follow-up duration was 16+/-6 months (range:7-28). MVA increased from 0.9+/-0.2 cm2 to 1.9+/-0.3 cm2 after PMV and decreased to 1.7+/-0.3 cm2 on follow-up TEE significantly. TMG decreased from 15.4+/-4.3 mmHg to 5.5+/-1.9 mmHg after PMV and was 6.2+/-2.4 mmHg on follow-up. S increased significantly on follow-up at both pulmonary vein (PV). D increased on follow-up at left PV. S/D ratio increased on follow-up at both PV. AR increased on follow-up at both PV. S-TVI increased after PMV at left PV and increased on follow-up at both PV. D-TVI had no change. S-TVI/D-TVI ratio increased on follow-up at left PV. AR-TVI increased on follow-up at right PV. CONCLUSIONS: The main changes after PMV in patients with MS in sinus rhythm were increasing tendency in S, S-TVI, S/D ratio, S-TVI/D-TVI ratio and AR. And these changes were statistically significant on follow-up TEE rather than immediately after PMV.

We analized the results of treatment in 28 children with high hyperopic amblyopia or astigmatic amblyopia among 65 amblyopic children ranging from 3 to 10 years of age from Jan. 1985 to Dec. 1989. The results are as follows: 1. The final corrected visual acuities of both eyes above 0.8, according to Han's visual acuity chart, were attained in 7 cases (50.0%) among children with high hyperopic amblyopia and 4 cases (28.6%) among children with astigmatic amblyopia. 2. As the degree of hyperopic errors increased, initial corrected visual acuity decreased (p<0.05). 3. The initial corrected visual acuity was not associated with the degree of hyperopic errors, but could be correlated with the initial visual acuity examination under 5 years of age (p<0.025). 4. The final corrected visual acuity recovered was above 0.8, (with Han's visual acuity chart) in 11 eyes (78.6%) among 14 eyes with high hyperopic amblyopia under 5 years of age However above 6 years of age, only one eye (12.5%) among 8 eys was correctable. 5. As the degree of astigmatic errors increased, the final corrected visual acuity decreased (p<0.025).

14 cases of femoral shaft fractures were treated with cast-brace for two years from June, 1974 to June, 1976 at the Department of Orthopedic Surgery, College of Medicine, Seoul National University Hospital. The results were as followings; 1. Of the 14 cases, eleven cases were male and three were female, and they were between 18 to 51 years of ages. 2. The fracture site was accounted that three of 14 cases were at the distal one third of the femur and the other eleven at the mid one third with four cases being comminuted. 3. 7 cases were treated with cast-brace initially, and the other 7 cases were secondarily treated, because of being complicated. 4. The average time of fracture healing was 14 weeks in the cases with cast-brace which is compared with 20 weeks of spica-cast control group in the same period. 5. One of 7 cases treated primarily developed shortening and angulation, which was corrected by open reduction and internal fixation.

We performed ERCP manometry of Sphincter of Oddi(SO) before and after endoscopic sphincterotomy(EST) for evaluation of the effect af EST on the SO. The subjects were postcholecystectomized common bile duct stone patients(n=l2) and EST was performed by major incision. The pressure gradient between common bile duct and duodenum before EST (8.6 + 3.9 mmHg) decreased significantly after EST(2.4 +1.7 mmHg). The length of SO before EST(8.8 + 0.8mmHg) decreased significantly after EST(2.5 + 0.8mm). But in each patient, the pressure gradient between common bile duct and duodenum remained in spite of the major incision. In conclusion, EST alters the function of the sphincter of the Oddi, but does not destroy its all protective function. The positive pressure in the bile duct is preserved in contrast to the absolute loss of pressure following surgical transduodenal sphincteroplasty.

From July 1989 to August 1991, we performed 146 cases of endoscopic sphincterotomy(EST). In our series, 9 early complications occurred in 146 cases(morbidity rate: 6.2%), and no fatalities were recognized(mortality rate:0). Four cases with late complications consisted of 2 cases of acute cholecystitis, one case of chalaagitis and restenosis. There were 36 with the gallbladder with stone(11 cases) or without stone(25 cases). Two cases with chalecystitis after EST occurred in the patients with gallbladder stones. EST gives the sufficient result in diagnosis and treatment for various disease of biliary tract. Furthermore, EST was found to be a safe procedure from low rates of complications and fatalities.

Expandable metallic stents(EMS) were implanted in 7 patients with malignant (4 cholangio- carcinnoma, 1 pancreatic cancer, 1 ampullary carcinoma and 1 lymph node metastasis) biliary stricutres and 17 patients with benign(13 intrahepatic strictures of primary intrahepatic stone patients, 2 postoperative stricutres, 1 ampullary stenosis followed by endoscopic sphineterotomy and 1 bilioenteric anastomosis) biliary stricutures. In the fifteen patients out of 17 patients with benign biliary stricture, relief of cholangitis, improvement of liver function or loss of pruritus was observed. But in the 2 patients with.biliary cirrhosis, no clinical improvement was noted. In the malignant strictures with cholangio-carcinoma, the occlusion of EMS occurred in 3 patients and the duration of stent patency was average 2 months in those patients.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.

Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

We reviewed the result of one-stage hypospadias repair of 32 cases, from Jan. 1989 to Dec. 1994, according to the site of urethral opening after release of chordee. The following results were obtained. 1. The posterior hypospadias (posterior penile, penoscrotal) was 18 cases and the anterior & middle hypospadias was 16 cases. 2. Success rate of posterior hypospadias repair was 9/18(50%) and that of anterior & middle hypospadias was 9/16(56.3%), it was not different statistically (P<0.05). 3. Complication rate of posterior hypospadias repair was 9/18 (50%) and of anterior & middle hypospadias was 7/16(43,5%), it was not different statistically (P<0.05) and complications were managed by simple procedure and require no further treatment. In condition, one stage repair of hypospadias could be applicable in most cases of hypospadias. The complication and morbidity were minimal.
