Main bronchial reconstruction is anatomically suitable for benign main bronchial stenosis. But, it has been hardly recommended for operative mortality and morbidity. This study was aimed at providing validity and the proper clinical information of bronchoplasty for benign main bronchial stenosis by reviewing the results we obtained over the last ten years for main bronchial reconstruction operations. We retrospectively reviewed admission and office records. Twenty eight consecutive patients who underwent main bronchoplasty were included. Enrolled patients underwent main bronchial reconstruction for benign disease (tuberculosis in 21, trauma in 4, endobronchial mass in 3). Concomitant procedures with main stem bronchoplasty were performed in 19 patients. There were no incidences of postoperative mortality and significant morbidity. There were 2 cases of retained secretions, and these problems were resolved by bronchoscopy or intubation. All of the patients are still alive without obstructive airway problem. Bronchoplasty should be considered as one of the primary treatment modalities, if it is anatomically feasible.

PURPOSE: There have been several recent reports of laparoscopy-assisted procedure for limited, or a laparoscopic, resections of small lesion of the liver. However, there are few reports on total laparoscopic surgery in anatomic resections, which is due to high level of skill required for the procedure and the risk of an air embolism. The aim of this study was to determine the safety of total laparoscopic surgery in anatomic liver resections during our early experiences. METHODS: The 6 patients included in this study were all treated with a totally laparoscopic anatomic resection of the liver at Ewha Womans University, Mokdong Hospital between September 2002 and January 2003. All 6 cases were diagnosed with an intrahepatic duct (IHD) stone, with stricture and/or common bile duct (CBD) stones. Of these 6 cases, 2 underwent a totally laparoscopic left lateral segmentectomy of the liver. In the remaining 4 cases, totally laparoscopic left lobectomies and CBD explorations, with T-tube insertion, were performed. In all cases, 4 trocars were used. During the operation, the intraperitoneal pressure of the pneumoperitoneum was maintained between 8 and 12 mmHg using CO2. The instruments used included Ligasure(R), Autosonix(R), 0 degrees and 30 degrees camera, fan retractor, Endo(vascular)- GIA 30 , and a large LapBag(R). All cases were managed in the supine position, with 15 degrees of left tilting. The specimen were extracted through a 4 to 5 cm extension of the upper trocar site. The T-tube exited through a 12mm site in the right upper port, and a drain was inserted into the sub-hepatic area. RESULTS: The patients comprised of 5 women and a man, with a mean age of 50.2 years old. The mean operative time was 469.2 (+/-141.4) minutes. In one case, 2 pints of packed red blood cells had to be transfused during the operation. The mean time to diet was 3.3 days. The mean postoperaitve hospital stay was 11.7 days. There was no conversion to open surgery, morbidity or mortality. The mean extensional incision size for the extraction of the specimen was 4.3 cm. CONCLUSION: In the anatomic resection of the liver, especially for benign liver disease, a total laparoscopic resection could be another relatively safe option for selected cases.

BACKGROUND AND OBJECTIVES: This study sought to investigate operative and late mortality in aortic valve surgery and to identify risk factors for operative and late mortality. MATERIALS AND METHODS: We examined operative mode, operative and late mortality, and survival rate of aortic valve surgery performed at Asan Medical Center between June 1989 and December 1996. RESULTS: 227 patients (148 men) with a mean age 49+/-15 years underwent aortic valve surgery. Aortic valvular lesions were classified as dominant stenosis (n=66), dominant regurgitation (n=133), and balanced stenoinsufficiency (n=28) according to the echocardiographic findings. Surgical procedures were aortic valve replacement with mechanical prosthesis in 180 (79 %) and with bioprosthesis in 27 (12 %) and aortic valve repair in 20 (9 %). The overall operative mortality was 4.8 %. Bacterial endocarditis and long bypass time were independent factors associated with high operative mortality (p < 0.05). During follow up (mean 33+/-24 months) of operative survivors, there were 9 late deaths, 12 re-do operations, and 11 clinical events (bacterial endocarditis, stroke, major bleeding, and admission for heart failure). There was no single identifiable risk factor for late mortality but age was significantly associated with development of clinical event and late mortality (p < 0.05). One-, Three-, and Seven-years survival rate after successful operation were 98+/-1 %, 96+/-2 %, and 92+/-3 %, respectively. Late clinical event-free survival rate was 67+/-8 % at seven years after aortic valve surgery. CONCLUSIONS: Aortic valve surgery could be done with low operative and late mortality. Complications related with bacterial endocarditis and long-term anticoagulation therapy following valve replacement surgery still remained high, which needs further improvement.

Acute abdominal Aortic occlusion is rare but it is a vascular emergency with high mortality and morbidity. Therefore, delay in diagnosis can have severe impact on the prognosis. A 60-year-old women complained of paresthesia, paralysis, and severe pain in bilateral lower extremities on 13th day after open heart surgery for mitral stenosis, atrial fibrillation, coronary arterial stenosis, tricuspid regurgitation, and atrial septal defect. Her skin was mottled and cool from the umbilicus to the feet, and there were no palpable pulses in the lower exteremities. We diagnosed an acute abdominal aortic occlusion using the Multi-Detector Row Spiral Computed Tomography and successfully treated the problem with emergent thrombo-embolectomy and Aortobifemoral bypass.

BACKGROUND: Bronchial sleeve resection for centrally located primary lung cancer is a lung- parenchyma-sparing operation in patients whose predicted postoperative lung function is expected to diminished markedly. Because of its potential bronchial anastomotic complications, it is considered to be an alternative to pneumonectomy. However, since sleeve lobectomy yielded survival results equal to at least those of pneumonectomy, as well as better functional results, it became and accepted standard procedure for patients with lung cancer who have anatomically suitable tumors, regardless of lung function. In this study, from analyzing of occurrence rate of postoperative complication and survival rate, we wish to investigate the validity of sleeve resection for primary lung cancer. MATERIAL AND METHOD: From January 1989 to December 1998, 45 bronchial sleeve resections were carried out in the Department of Thoracic Surgery of Seoul National University Hospital. We included 40 men and 5 women, whose ages ranged from 23 to 72 years with mean age of 57 years. Histologic type was squamous cell carcinoma in 35 patients, adenocarcinoma in 7, and adenosquamous cell carcinoma in 1 patients. Right upper lobectomy was performed in 24 patients, left upper lobectomy in 11, left lower lobectomy in 3, right lower lobectomy in 1, right middle lobecomy and right lower lobectomy in 3, right upper lobectomy and right middle lobecomy in 2, and left pneumonectomy in 1 patient. Postoperative stage was Ib in 11, IIa in 3, IIb in 16, IIIa in 13, and IIIb in 2 patients. RESULT: Postoperative complications were as follows; atelectasis in 9, persistent air leakage for more than 7 days was in 7 patients, prolonged pleural effusion for more than 2 weeks in 7, pneumonia in 2, chylothorax in 1, and disruption of anastomosis in 1. Hospital mortality was in 3 patients. During follow-up period, bronchial stricture at anastomotic site were found in 7 patients under bronchoscopy. Average follow-up duration of survivals(n=42) was 35.5+/-29 months. All of stage I patients were survived, and 3 year survival rate of stage II and III patients were 63%, 21%, respectively. According to N stage, all of N0 patients were survived and 3 year survival rates of N1 and N2 were 63% and 28% respectively. CONCLUSION: We suggest that this sleeve resection, which is technically demanding, should be considered in patients with centrally located lung cancer, because this lung-saving operation is safer than pneumonectomy and is equally curative.

The main goals of coronary artery bypass grafting (CABG) are to relieve chest pain and to improve quality of life by bypassing all coronary artery segments with severe stenosis. It is a common surgical procedure on the heart. Until recently, most surgeons have used cardiopulmonary bypass (CPB) to provide a motionless and bloodless operation field to accomplish optimal microvascular anastomoses. However, CPB may have adverse sequelae, such as cerebrovascular accident, renal failure, and higher intellectual impairment, because of an inflammatory response caused by the blood circulating through the extracorporeal circuit and the formation of microemboli. In recent years, advances in retractor-stabilizer systems and in operative techniques that allow an access to all coronary artery segments have brought a growing attention to beating heart surgery without CPB (offpump coronary artery bypass grafting, OPCAB). OPCAB significantly lowers in-hospital morbidity and mortality compared with CABG. Heart failure after myocardial infarction poses a growing medical challenge as the life expectancy continues to increase. Recently it affects 0.4~1% of the overall population and 5% of elderly subjects. Although cardiac transplantation, a gold standard surgery for heart failure, provides excellent therapeutic outcomes in some patients with terminal stage of the disease, the overall outcomes are limited by the scarcity of donor organs, reduced long-term survival, and co-morbid conditions. Recently the efficacies of left ventricular volume reduction surgery, mitral valve repair, and bone marrow cell transplantation in improving the heart function in infracted myocardium of a failing heart have been extensively evaluated and were shown to result in good outcomes.

The anastomotic complications following radical gastrectomy mainly include anastomotic leakage, anastomotic hemorrhage, and anastomotic stricture. Theanastomotic complications are not rare and remain the most common complications resulting in the perioperativedeath of patients with gastric cancer. Standardized training could let surgeons fully realize that strict selection of operative indications, thorough preoperative assessment and preparation, and refined operation in surgery are the essential measures to prevent the anastomotic complications following radical gastrectomy. In addition, identifying these complications timely and taking effective measures promptly according to the clinical context are the keys to treating these complications, reducing the treatment cycle, and decreasing the mortality.

To analyze two common factors for perioperative ischemic stroke in patients with concomitant carotid and coronary artery severe stenosis and to improve the therapeutic effect.
 Methods: A total of 44 patients with multi-vessel coronary artery disease combined with carotid stenosis, who admitted to the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University from 2008 to 2014, were enrolled in this study. Among them, 32 cases were male, 12 cases was female. All patients received coronary artery bypass grafting after treatment of neck diseases. The surgical outcomes and follow-up results were analyzed retrospectively.
 Results: One patient received carotid endarterectomy suffered hemiplegia, whose symptoms were improved after positive clinical treatment. One patient suffered transient ischemic attack, and 5 patients displayed the cerebrovascular syndromes a week later after surgery. Twelve patients suffered nerve function damage 48 hours later after surgery. Nine patients received intra-aortic ballon pump, 1 patient received thoracotomy hemostasis, 3 patients suffered sternal dehiscence; 27 patients showed atrial fibrillation. Two patients died after surgery. The follow-up duration ranged from 1-7 years and the follow-up rate was 90%. The ischemic symptoms were improved in 44 patients. Six patients complained the recurrence of angina, but no abnormalities were found in coronary angiography or computed tomography angiography. One patient died of malignant tumor during the follow-up duration.
 Conclusion: For patients with concomitant carotid and coronary artery severe stenosis, it is more likely to suffer ischemic cerebral stroke. However, carotid stenosis is not the only factor, other key factors relevant to ischemic cerebral stroke shouldn't be ignored either.
