PURPOSE: Septic arthritis of the knee is a relative rare complication of the arthroscopic anterior cruciate ligament reconstruction, but inadequate treatment of this complication may lead to a devastating conse- quence of a chronic infection. Moreover, no guidelines have been proposed for the treatment of patients with knee infections after the anterior cruciate ligament reconstruction. To determine the optimal diagno- sis and treatment recommendation, we performed this study. MATERIALS AND METHODS: We performed retrospective study of the knee joint infections after the arthroscopic anterior cruciate ligament reconstruction between August 1993 and August 1998, Of the 420 patients who reviewed arthroscopic ACL reconstruction during this period from one surgeon, we experi- enced 4 cases(0.95%) of postoperative deep infections of the knee. RESULTS: All 4 patients were male, and the average age was 32 years(range from 19 to 43). Two patients had acute(< 2 weeks), two patients had subacute infections(2 weeks to 2 months). The acute cases had more severe symptoms, and positive cultures from knee joint aspirates. All patients underwent immediate open(1 case), or arthroscopic irrigation and debridement. One patient underwent repeat irriga- tion and debridement. The graft was removed from all patients in acute cases. CONCLUSION: The clinical symptoms, and the infected organism were more helpful than the peripheral blood counts in the diagnosis of a deep infection of the knee. Arthroscopic lavage, and debridement com- bined with intravenous antibiotics were effective treatment options. Clinical symptoms were more severe in acute cases, and early graft removal is an adequate method of surgical treatment.

A choledochocele is a benign cyst-like herniation of the intramural segment of the distal common bile duct protruding into the duodenal lumen. Cholangiography is essential to demonstrate a choledochocele. Because choledochoceles are often associated with characteristic structual alterations of the papilla of Vater and the peripapillary area, ERCP is helpful in demonstrating a choledochocele. We present the clinical, endoscopic and radiographic (ERCP) findings in a patient with choledochocele.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.
