Total anomalous pulmonary venous connection [TAPVC] defines a group of congenital heart disease which have in common the entire pulmonary venous drainage returning directly or indirectly to the right atrium instead of to the left atrium. Although this disorder represents only 1.3% of cases of congenital heart disease, if untreated the resultant mortality is greater than 80% in the 1st year of life. And since there is no satisfactory palliative treatment, correction of TAPVC Is high on the list of indications for open heart surgery in the 1st year of life. This paper describes 10 patients who underwent surgical correction of this disorder at SNUH between 1978 and 1983. 1. 7 were males and 3 females, with ages ranging from 5 months to 24 years. 2. 7 were supracardiac type, 2 cardiac type, and 1 mixed type TAPVC. We didnt experience infracardiac type. 3. All showed some degree of pulmonary hypertension preoperatively. 4. In 4 cases of supracardiac type, total circulatory arrest was used in brief period during anastomosis between common pulmonary venous trunk and left atrium. In the other cases, usual cardiopulmonary bypass with moderate to deep hyperthermia was used. 5. There were 2 cases of mortality; 1 died at operation, and the other at 4 months due to congestive heart failure. 6. Mortality seemed not closely related to age, body weight, or severity of pulmonary hypertension.

Surgical therapy for dissection of the aorta has had a high mortality. One contributing factor has been hemorrhage from the prosthesis and the suture lines. Recently, a new method of treatment with an intraluminal graft that requires no end-to-end anastomosis has been developed. Of the four patients with dissecting aneurysm of the aorta treated by inserting sutureless ringed intraluminal graft at the Department of Thoracic and Cardiovascular Surgery, S.N.U.H., three were DeBakey type I [one with associated aortic insufficiency] and the other was DeBakey type III. Suspected etiology of the dissection was Marfan`s syndrome in one and hypertension in the others. Total cardiopulmonary bypass was utilized in repairing dissecting aneurysms of the ascending aorta [type A] and simple aortic crossclamping was used for the patient with dissecting aneurysm of the descending aorta. The basic technique consists of inserting the whole ringed graft into the true lumen of the dissected aorta and circumferentially ligating the aorta against the groove in the rings. The proximal ring of the graft effectively stabilized the flail aortic valve in patient with aortic insufficiency associated with dissection of the ascending aorta. There were no hospital deaths and one patient with type III dissecting aneurysm developed postoperative paraparesis and renal insufficiency which was resolved. Follow-up has been from 1 month to 16 months with no evidence of prosthetic problems, such as erosion, migration, or thrombosis.

The application of laparoscopic techniques for the surgical management of Hirschsprung's disease is the recent trend. We described the surgical technique and postoperative long-term outcomes of the one-stage, laparoscopic-assiseted endorectal pull-through operation for Hirschsprung's disease. The technique uses three to four small abdominal ports. Laparoscopic mobilization of the sigmoid colon and rectum is performed and marginal artery-preserving colon pedicle is prepared. The rectal mobilization is performed using a transanal endorectal sleeve technique. The anastomosis is performed 0.5~1 cm above the dentate line. The age at surgery ranged from 6 days to 4 years. The average operative time was 144 minutes. Almost all of the patients passed stool and flatus within 36 hours of surgery. The average hospital stay after surgery was 6.5 days. Among 42 patients, 32 patients older than 3 years old were evaluated for function on defecation. All 32 patients have been continent, of those who needed laxatives were 11 (34.3%) due to constipation and overflow incontinence. Four children (12.5%) have remained dependent on laxatives. Laparoscopic-assisted endorectal pull-through operation for Hirschsprung's disease appears to be safe, provides the less pain, shorter time to full feeding, shorter hospital stay, and excellent cosmetic outcomes. Helping patients and parents ensure the quality of life, they should be provided with counseling, education, and longer-term follow-up care.

The purpose of this study was to review the literatures of experimental tracheal reconstruction. Although there have been significant advancements in the surgical treatment of the long circumferential tracheal injuries, there still has been a difficult problem with high morbidity and mortality. The method for tracheal reconstruction after circumferential resection is preferred end-to-end anastomosis for defects up to 6 cm in length, but larger tracheal defects require the use of tracheal allograft, various artificial prosthesis or autogenous organs. The tracheal allotransplantation has been widely used as there was significantly improved the method of surgical technique, preservation and immunosuppression. But it has been limited by a number of factors such as few donor, limited use of immunosuppressant, delayed revascularization and re-epitheliazation. Experimental studies on the tracheal prosthesis have a long history and they tried to use silicone, polytetrafluoroethylene, polypropylene mesh, Dacron, Marlex mesh, external or internal stents. Other experimental studies were reported the use of autogenous tissues that were cartilage. jejunum, aorta, skin, muscle, periostium or esophagus. But a great variety of these protheses have been resulted unsatisfactory in a significant Proportion of cases. Alternatively, the tissue-engineering technique has showed a new approach to reconstruct trachea and much progress in tissue-engineering bas been made recently. In conclusion, although the tracheal allotransplantation and the use of prosthesis and allograft have been reported a lot of limitation to overcome, we could sooner expect good result of ideal tracheal prosthesis.

Between November, 1981 and July, 1989, 4 patients, 3 male and 1 female patients ranging in age from 36 to 45 years, were operated on for aortic insufficiency associated with uncomplicated annuloaortic ectasia. All patients were in New York Heart Association class III. Two patients had clinical stigmata of the Marfan syndrome. The surgical treatment consisted of. supracoronary replacement of ascending aorta with vascular graft and replacement of the aortic valve in our first case. and composite graft replacement of the ascending aorta and aortic valve with reimplantation of the coronary arteries in subsequent 3 cases. Our first patient developed aneurysm of proximal aorta and pseudoaneurysm of distal aortic anastomosis 5 years postoperatively. One patient among the three patients with Ben-tall operation, died of ventricular fibrillation and myocardial failure during immediate postoperative period. Remaining 2 patients were in NYHA class I with follow-up of 16 months and 20 months respectively.

Pulmonary atresia with intact ventricular septum, and with VSD were uncommon congenital anomalies with high mortality in the neonatal period. Those survivals depend on an adequate interatrial communication or interventricular communication and pulmonary flow via large aortopulmonary collateral including PDA. Recently we experienced surgical correction of 2 cases pulmonary atresia with intact ventricular septum and with VSD. On case 1, 10-years old male patient was confirmed as pulmonary valvular membranous atresia with intact ventricular septum combined with large functioning PFO and mild tricuspid incompetence. So we performed total correction under the E.C.C, that was PDA ligation, RVOT reconstruction with monocusp valved outflow patch [16mm], repair of tricuspid insufficiency and closure of PFO. Post-operative hemodynamic result was good and there was no event during hospital course. On case 2, 16-years old female patient was diagnosed as pulmonary atresia with VSD and PDA. MPA was absent, remained fibrous cord like remnant and type of VSD was subaortic defect [3cm by 3cm in the size]. PDA was located at the usual site. Under the E.C.C. VSD patch closure through the right ventriculotomy, anastomosis between the right ventricular outflow tract and the pulmonary bifurcated site with the extra-cardiac Hancock valved conduit [22cm] and PDA ligation were performed.

Characterizing inflammation and fibrosis in Crohn's disease (CD) is necessary to guide clinical management, but distinguishing the two remains challenging. Novel ultrasound (US) techniques: contrast-enhanced US (CEUS) and shear wave elastography (SWE) offer great potential in evaluating disease activity in pediatric patients. Three patients ages 16 to 20 with known CD underwent CEUS and SWE to characterize bowel wall inflammation and fibrosis. Magnetic resonance enterography, endoscopy, or surgical pathology findings are also described when available. The patients' disease activity included acute inflammation, chronic inflammation with stricture formation, and a fibrotic surgical anastomosis without inflammation. CEUS was useful in determining the degree of inflammation, and SWE identified bowel wall fibrosis. Used together these techniques allow for better characterization of the degree of fibrosis and inflammation in bowel strictures. With further validation CEUS and SWE may allow for improved characterization of bowel strictures and disease flares in pediatric patients suffering from CD.

Objectives : The goal of the surgical management of large and giant aneurysm is complete extirpation of the aneurysms with preservation or reconstruction of the parent artery. To improve the surgical management results of those aneurysms in the future, we review our experience and discuss technical maneuvers and strategies used to avoid potential complications of those aneurysm surgery. Material and Methods : During the past 12 years, thirty six cases of large and giant aneurysms(diameter>19mm) were managed by surgery. The clinical characteristics, treatment methods, surgical complications and outcome of those cases were analyzed and, based on the review of the literatures, the preventive methods of surgical complication related to the clipping of those aneurysms were discussed. Results : The locations of those aneurysms were anterior circulation in 34 cases and posterior circulation in 2 cases. The most frequent site of aneurysmal location was a paraclinoidal region of the anterior circulation. The aneurysms were managed surgically by direct clipping of aneurysmal neck in 31 cases, aneurysmal trapping followed by extracranial-intracranial bypass in 2 cases, proximal clipping of parent artery, aneurysmorrhaphy, and excision of aneurysm followed by end to end anastomosis of parent artery in each one case. Surgical complications occurred in 13 cases. A parent vessel occlusion by thrombus formation and parent vessel stenosis after clipping of aneurysm were the main complications. We obtained good outcome in 27, fair 5, poor 1 and dead in 3 case(s). Conclusion : We conclude that selection of suitable management method for each case, high quality of surgical technique and prevention of complication during operation are important key points for the successful treatment of large and giant aneurysm. The heparinization prior to application of temporary clip on parent vessels, aneurysmal decompression during dissection and clipping of aneurysm, complete closing of the aneurysmal neck and avoiding the narrowing of parent vessel after clipping of aneurysm were the main technical maneuvers used to avoid complications of those aneurysm surgery.

Laparoscopic gastrectomy has been widely accepted especially in patients with early-stage gastric cancer. However, the safety and oncologic validity of laparoscopic gastrectomy for advanced gastric cancer are still being debated. Since the late 90s', we have been engaged in developing a stable and robust methodology of laparoscopic radical gastrectomy for advanced gastric cancer, and have established laparoscopic distinctive technique for suprapancreatic lymph node dissection, namely the outermost layer-oriented medial approach. In this article, We present the development history of this method, and current status and future perspectives of laparoscopic gastrectomy for advanced gastric cancer based on our experience and a review of the literature.

The tendinous ends of neglected achilles tendon rupture tend to retract and separate with atrophy due to gastrosoleus muscle contracture, leaving a wide gap occupied with fibroadipose scar tissue. It is almost impossible to perform simple end-to-end anastomosis after the intervening scar tissue being excised. Therefore many surgical procedures have been proposed to reconstruct the large gap. We treated three such cases by V-Y advancement flap and double Krackow suture technique, and their postoperative strength of triceps surae were evaluated with Cybex isokinetic strength testing. All patients returned to preinjury activities with satisfaction, but the ankle plantar flexor power showed about 20-30% deficit.
