Purpose: The safety and efficacy of minimally invasive techniques in congenital heart surgery were tested in this study. Materal and method: Between July 1997 and November 1997, a total of 46 children were underwent minimally invasive cardiac operations at Seoul National University Children's Hospital. Age and body weight of the patients averaged 34.6${\pm}$41.8 (Range: 1∼148) months and 14.5${\pm}$9.9(Range: 3.0∼40.0) kg, respectively. Twenty eight patients were male. Preoperative surgical indications included 15 atrial septal defects, 25 ventricular septal defects, 1 foreign body in aorta, 3 partial atrioventricular septal defects, 1 total anomalous pulmonary venous connection(cardiac type), and 1 tetralogy of Fallot. After creating a small lower midline skin incision starting as down as possible from the sternal notch, a vertical midline sternotomy extended from xyphoid process to the level of the second intercostal space, where one of the T-, J-, I- or inverted C-shaped lower lying mini-sternotomy was completed with a creation of unilateral right or bilateral trap door sternal opening. A conventional direct aortic and bicaval cannulation was routine. Result: A mean length of skin incision was 6.1${\pm}$1.0(range: 4.0∼9.0) cm. A mean distance between the suprasternal notch and the upper most point of the skin incision was 4.0${\pm}$1.1 (range: 2.0∼7.0) cm. Mean cardiopulmonary bypass time, aortic cross-clamp time, and the operation time were 62.9${\pm}$20.0(range: 28∼147), 29.8${\pm}$12.8(range: 11∼79), and 161.1${\pm}$34.5 (range: 100-250) minutes. A mean total amount of postoperative blood transfusion was 71.0${\pm}$68.1 (range: 0∼267) cc. All patients were extubated mean 11.3${\pm}$13.8(range: 1∼73) hours after operation. A mean total amount of analgesics used was 0.8${\pm}$1.8(range: 0∼9) mg of morphine. The mean duration of stay in intensive care unit and hospital stay were 35.0${\pm}$32.2 (range: 10∼194) hours and 6.2${\pm}$2.0(range: 3∼11) days. There were no wound complications and hospital deaths. Conclusion: This short-term experience disclosed that the minimally invasive technique can be feasibly applied in a selected group of congenital heart disease as well as is cosmetically more attractive approach.

Advanced age in Esophagectomy increases the risk of postoperative morbidity and mortality. However, the recent development of operative technique and perioperative care might have decreased the postoperative morbidity and mortality after esophagectomy. Material and Method: From March 2001 to July 2004, 174 patients underwent esophageal resection for esophageal cancer in the Center for Lung Cancer, National Cancer Center. The patients were divided into two groups : group 1 consisted of 27 patients aged 70 years or more, and group 2 consisted of 147 patients under 70 years of age. The two groups were compared according to preoperative risk factors, postoperative morbidity, operative mortality and survival. Result: The mean age was 63_4. There were 159 men. On histopathological examination, $93.1\%$ had squamous cell carcinoma. On the locations, $78.7\%$ were in mid and lower esophagus. Curative resections for esophageal cancer were possible in $162(93.1\%)$ patients. Mean hospital stay was 19.4 days with out difference between the groups. The overall postoperative morbidity were occurred in 61 patients $(35.1\%)$. The most frequent morbidity was pulmonary complication in $30(17.2\%)$. Preoperative incidence of hypertension, cardiac and pulmonary dysfunction were more common in Group I. However, there was no difference in overall postoperative morbidity, operative mortality and survival rate between the two groups. Conclusion: Esophagectomy for esophageal cancer could be carried out safely in patients over 70 years of age with satisfactory short-term results. Advanced age is no longer a risk factor for esophagectomy.
