Purpose: Tracheobronchial injuries caused by trauma are rare, but can be life threatening. The objective of this study was to evaluate the surgical outcome for patients with tracheobronchial injuries and to determine the difference, if any, between the outcomes for patients with penetrating trauma and those for patients with blunt trauma. Methods: From January 2010 to June 2015, 40 patients underwent tracheobronchial repair surgery due to trauma. We excluded 14 patients with iatrogenic injuries, and divided the remaining 26 into two groups. Results: In the blunt trauma group, injury mechanisms were motor vehicle accident (9 cases), free falls (3 cases), flat falls (1 case) and mechanical injury (1 case). In the penetrating trauma group, injury mechanisms were stab wounds (10 cases), a gunshot wound (1 case) and a stab wound caused by metal pieces (1 case). The mean RTS (Revised Trauma Score) was $6.89{\pm}1.59$ (range: 2.40-7.84) and the mean ISS (Injury Severity Score) was $24.36{\pm}7.16$ (range: 11-34) in the blunt group; the mean RTS was $7.56{\pm}0.41$ (range: 7.11-7.84), and the mean ISS was $13{\pm}5.26$ (range: 9-25) in the penetrating trauma group. In the blunt trauma group, 9 primary repairs, 1 resection with end-end anastomosis, 2 lobectomies, 1 sleeve bronchial resection and 1 pneumonectomy were performed. In the penetrating trauma group, 10 primary repairs and 2 resections with end-end anastomosis were performed. Complications associated with surgery were found in one patient in the blunt trauma group, and one patient in the penetrating trauma group. No mortalities occurred in either groups. Conclusion: Surgical management of a traumatic tracheobronchial injury is a safe procedure for both patients with a penetrating trauma and those with a blunt trauma.
In spite of great advances in surgical treatment during past several decades, surgery of the trachea failed to develop correspondingly, partly because of relative rarity of the tracheal lesions and partly because of difficulties in surgical technique and anesthesia. Surgical diseases of the trachea are largely obstructions due to neoplasm or cicatrical stenosis and tracheal malacia. The present treatment of respiratory failure, using cuffed endotracheal and tracheostomy tubes, has produced, apparently with increasing frequency, tracheal stenosis, tracheomalized tracheal erosion. Surgery is presently the only reasonable way to treat stenotic lesions of the tracheobronchial tree. In the case of tumors, the current trend has been that of radical excision. Primary end-to--end reconstruction of the trachea has been generally recognized as the ideal method of repair following resection. However, for decades it was believed that a maximum of four tracheal rings only might be excised and primary healing achieved with safety. A great variety of procedures, developed by numerous investigations and directed at tracheal substitution, have almost invariably met with discouraging results. A meticulous study done by Grillo and associates on autopsy specimens has shown that an average 6.4cm of mediastinal trachea can be safely resected by full mobilization of the right lung and transplantation of the left main bronchus into the bronchus intermedius. Recently, we experienced a case of successful resection of a tumor of the tracheal carina and primary tracheo-left main bronchial anastomosis at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul. The patient, a 29-year-old man, was admitted to the hospital with complaints of dyspnea and cough. On admission, chest film showed hydropneumothorax on the right. After closed thoracostomy, hydropneumothorax disappeared, but hazy densities, developed in the right middle and lower lung fields, resisted to treatment. Bronchoscopy uncovered irregular tumor covering the carina and the right main bronchus, and biopsy indicated well differentiated squamous Cell carcinoma. Operation was performed on July 2, 1975. A right postero-lateral thoracotomy was used. Excision involved the lower trachea, the carina, the left main bronchus and the right lung. This was followed by direct anastomosis between the trachea and the left main bronchus. Bronchography was done on 17th postoperative day revealed good result of operation without stricture at the site ofanastomosis. About one month after the operation symptoms and signs of bronchial irritation with dyspnea developed, and these responded to respiratory care. On 82nd postoperative day, sudden dyspnea developed at night and the patient expired several hours later. Autopsy was not done and the cause of death was uncertain.

Background: Cardiac involvement of Behcets disease is very rate, however, the prognosis of Behcet disease depends on cardiovascular complications. In this article, we described surgical treatment of aortic insufficiency with Behcets disease. Material and Method: From March 1986 to February 1998, we operated on 10 patients of aortic insufficiency with Behcets disease. Male to female ratio was 8 to 2, and age ranged from 21 to 40 years(mean 32.8 years). There were 8 patients with evidence of Behcets disease and another 2 patients had some suspicious findings of Behcets disease(i.e., prosthetic value dehiscence, hypertrophied aortic wall). Adequate preoperative medical treatment for Behcets disease was done in 3 patients. Result: We performed 24 open heart surgeries in 10 patients. Redo value replacements using prosthetic valves were done in 4 patients. Among them, 2 patients were operated on for a second redo valve replacement and one of them operated on for a 4th and 5th operation because of recurrent paravalvular leakage. These 4 patients expired. 1 patient who had undergons tissue value replacement is alive. 1 patient who underwent Cabrol operation expired dut to rupture of graft anastomosis site. We used homografts in 3 patients. In 2 of them, we performed aortic root replacement and subcoronary valve replacement in another patient. The patient who underwent subcoronary valve insertion had remnant aortic insufficiency, so we are closely observing him. We also performed Ross operation in a 24 year old female who suffered severs aortic insufficiency and endocarditis after aortic valvuloplasty. 5 patients are alive and mean follow up duration is 49.0 months. Among them, we used homografts or sutografts in 4 patients. We could observe excellent clinical results in the patients who underwent aortic root replacement using homograft and they were treated medically for Behcets disease. Conclusion: We concluded that adequate preporative diagnosis, clinical suspicion, and periopertive medical treatment for Behcets disease are very important for the result of surgical management of aortic insufficiency with Behcets disease. The use of homograft or autograft was helpful for the healing of anastomosis site and we should carefully observe the long term follow up results.

Purpose: Synthetic absorbable monofilaments offer excellent glide characteristics and cause minimal tissue trauma as a result of their smooth monofilament structure and gradual absorption within the healing tissues. For these reasons, these suture materials are commonly used in various surgical fields such as gastroenterology, urology, gynecology, and plastic surgery. The aim of this study was to evaluate the safety and usefulness of a new synthetic absorbable monofilament, Glycoside-..-caprolactone-trimethylene carbonate interpolymer (GCT), in gastrointestinal anastomosis and closure. Materials and Methods: We evaluated 55 gastrointestinal anastomoses and closures using GCT $MONOSYN^{R}$, B. Braun, Germany) in 47 patients who underwent gastric surgery between December 2001 and May 2002 at Seoul National University Hospital. Patient's characteristics, operative procedure, surgeon's opinion of handling properties of GCT, and suture-related complications were analyzed. Results: There were 34 males and 13 females (M:F= 2.6:1) with an average age of 54.2 years old. Forty-five cases of gastrointestinal anastomosis (20 gastrojejunostomies and 25 jejunojejunostomies) and 10 cases of intestinal closure (7 gastrostomy closures and 3 duodenal stump closures) were performed in 41 cases of stomach cancer, three of peptic ulcer disease, two of GIST, and one MALToma. The handling properties of GCT according to the criteria of knot breaking load, knot security, and placing property were always scored with 7 to 9 points (10=excellent, 1=very poor). Two cases of postoperative complications ($3.6\%$) were noted. One was a leak of the gastrojejunostomy site which was successfully managed conservatively, and the other was a stricture of the gastrojejunostomy site which was managed by reoperation (side-to-side jejunojejunostomy). Conclusion: GCT seems to be an applicable suture material for various gastrointestinal anastomoses and closures.
Purpose: The purpose of this study is to evaluate the surgical outcome of duodenal injuries and to analyze the risk factors related to the leakage after surgical treatment. Methods: A retrospective review of 31 patients with duodenal injuries who managed by surgical treatment was conducted from December 2000 to May 2014. The demographic characteristics, injury mechanism, site of duodenal injury, association of intraabdominal organ injuries, injury severity score (ISS), abdominal abbreviated injury scale (AIS), injury-operation time lag, surgical treatment methods, complications, and mortality were reviewed. Results: Duodenal injury was more common in male. Twenty four (77.4%) patients were injured by blunt trauma. The most common injury site was in the second portion of the duodenum (n=19, 58.6%). Fourteen patients (45.2%) had other associated intraabdominal organ injuries. The mean ISS is $13.6{\pm}9.6$. The mean AIS is $8.9{\pm}6.5$. Eighteen patients (58.1%) were treated by primary closure. The remaining 13 patients underwent various operations, including exploratory laparotomy (n=4), pancreaticoduodenectomy (n=3), pyloric exclusion (n=3), Resection with end-to-end anastomosis (n=2), and duodenojejunostomy (n=1). Most common postoperative complications were intraabdominal abscess (n=9) and renal failure (n=9). Mortality rate was 9.7%. Conclusion: ISS, AIS>10, operative time, pancreaticoduodenectomy, sepsis, and renal failure are significant predictors of a postoperative leak after duodenal injury. Careful management is needed to prevent a potential leak in patient with these findings.

Objective : Surgical experiences of pseudoaneurysms such as traumatic, mycotic and ill-defined unknown causes of aneurysms are rare. The authors have studied the results of surgical management from such cases in our series. Patients and Method : In the last 17 years, 1320 patients with cerebrovascular aneurysms were managed surgically. Among these, 16 patients showed the pseudoaneurysms. The authors analyzed retrospectively the clinical characteristics, treatment methods, management outcomes and problems in the managements. Results : There were 6 patients with traumatic aneurysm, 4 mycotic aneurysms and 6 ill-defined unknown causes of aneurysm. The sites of traumatic aneurysms were cavernous portion of the internal carotid artery(n=3), distal portion of the anterior cerebral artery (n=2) and vertebral artery(VA : n=1). Good outcomes in 5 cases could be obtained by extracranial - intracranial bypass followed by parent vessel occlusion or resection of aneurysm followed by re-anastomosis of parent vessel. The sites of mycotic aneurysm were peripheral portions of middle cerebral artery(MCA : n=3) and posterior cerebral artery(PCA : n=1). The outcomes of the patients with a mycotic aneurysm were relatively poor. It was partially due to the development of new aneurysm after treatment in one. The sites of ill-defined unknown causes of aneurysm were extracranial carotid artery(n=3), V2 portion of the VA(n=1), peripheral portion of the PCA (n=1) and MCA(n=1). Good outcome in all cases could be obtained by resection of aneurysm with or without saphenous vein graft. Conclusion : For the treatments of cerebrovascular pseudoaneurysm, combinations of aggressive medical, endovascular and surgical managements seem mandatory. Insertion of stent for a extracranial carotid artery aneurysm and coiling for a peripheral mycotic aneurysm can be option in future.
We have performed eight, single transplantations of right lung in dogs from September, 1988 to March 1989 at the Thoracic & Cardiovascular Surgical department, Yonsei University, College of Medicine, Seoul, Korea. We wrapped bronchial anastomosis site with great omentum and used cyclosporin in preoperative and postoperative periods in seven cases except one. The one without wrapping the bronchial anastomotic site with omentum and using cyclosporin died due to bronchial anastomotic site rupture in postoperative fourth day. If there is no reason to choose one side over the other, we would generally choose to do left-sided transplant as this is technically somewhat easier because of the long length of recipient bronchus and the ease of clamping the left atrium proximal to the pulmonary veins. The right atrium limits the amount of left atrium that can have incorporated into the clamp proximal to the pulmonary veins on the right side. But we had chosen to do right-sided transplant of lung because we must take variable technical experiences on right sided lung transplant in dogs. We have to anastomose one of pulmonary vein and left atrial wall on right-sided transplant easily only with double ligation of one pulmonary vein because right atrium limited the clamp of left atrium proximal to pulmonary veins with decreased venous return and cardiac output in some dogs. All seven dogs with right-sided lung transplant had survived more than one day with good condition except one. The one dog have to be sacrificed to evaluate the difference between the gas analysis in pulmonary venous and arterial blood in post-operative eight hours. We found hemorrhagic pulmonary edematous changes of contralateral left lung in this dog. And also all dogs have to be sacrificed for the evaluation of surgical problems, anytime in post-operative periods without any cardiopulmonary resuscitative efforts when the general condition would be worse progressively. We found no any surgical technical errors in seven dogs except one with thrombi in suture site of left atrium. There were hemorrhagic pulmonary edematous changes of transplanted right lung in one, of contralateral left lung in one, of contralateral left lung with double ligation of its pulmonary artery in one, thrombi around left atrial sutures sites in one, multiple air leakage in one bronchial rupture in one due to rejection or infection. There were accidental extubation and delayed intubation in one and unknown cause of death in one.
We have performed left lung transplantation followed by ligation of right pulmonary artery in 14 dogs at the Chest Disease Research Institute, Yonsei University College of Medicine from May 1992 to February 1994. Excised left lung was perfused with 1500cc of 4$^{\circ}$C cold Euro-Collin`s[E-C] solution at a pressure of 30cmH2O through main pulmonary artery and preserved in 4$^{\circ}$C cold E-C solution for one hour. Left lung transplantation were proceeded in order of left atrium, left main bronchus, left pulmonary artery and right pulmonary artery ligation as usual method. The femoral artery and pulmonary artery pressures were monitored for more than 5 hours after the transplantations in 14 dogs. Six recipient dogs had elevated mean pulmonary artery pressure to greater than 30mmHg after the left lung transplantation and ligation of right pulmonary artery. The cause of elevated mean pulmonary artery pressure was due to inadequate preservation resulting in ischemic damage to donor lungs in 3 cases, and inadequate surgical techniques in 3 cases. Two recipient dogs without surgical complications died immediate post-operatively due to hemorrhagic shock. The bleeding focuses were LA anastomotic site in one case and femoral artery puncture site in another case. The remaining 6 recipient dogs showed mean pulmonary arterial pressure less than 30mmHg. However, one dog had spontaneous pneumothorax in post-operative 4 days, and another dog had rejection phenomenon in post-operative 5 days which was confirmed by pathologic findings of extracted transplanted lung. One dog succumbed of severe hemoptysis which was due to lung abscess with pin point stenosis of bronchial anastomosis in post-operative 38 days. In conclusion, elevated mean pulmonary arterial pressure greater than 30mmHg in immediate postoperative period can be due to inadequate preservation of extracted lung or poor surgical techniques. And the two dogs succumbed of hemorrhagic shock even though the mean pulmonary arterial pressure was less than 30mmHg. It is thought that careful preservation of the extracted donor lung in 4oC E-C solution and complete surgical techniques are the most important factors early and late complications.
The most important concern to do parotidectomy is correct identification of the facial nerve and preservation of the nerve function. Many descriptions for the localization and branching types of the facial nerve trunk have existed. During the parotid surgery, it is necessary to have knowledges about the incidence and prognostic aspect of a invasion of the facial nerve by the parotid tumors. The method of the dissection and the surgical extent of the parotid gland would be decided not only by the anatomic variation of the facial nerve. but also the size and location of the tumor. Invasion of the facial nerve in parotid malignancies is the most significant factors affecting the prognosis, so radical parotidectomy which consists of the total extirpation of the parotid gland in conjunction with resection of the facial nerve is often required for proper management. Radical parotidectomy is advocated for the surgical treatment of high grade malignancies and in selective recurrent benign tumors intimately involving the facial nerve. Unfortunately, the morphologic and functional deficits created by sacrificing the facial nerve can be emotionally and physically traumatizing to the patient. Therefore, when the facial nerve is sacrificed, immediate reconstruction of the facial nerve should be necessary. Immediate nerve repair with direct anastomosis of the resected nerve ends or placement of a cable nerve graft provides the better cosmetic and functional results. Surgical resection remains the mainstay of treatment for cancer of the parotid gland, and there is general agreement that facial nerve should not be sacrificed unless the tumor is adherent to, or surrounds the nerve. The following statement is described general principles of troublesome management of the facial nerve during surgery for parotid tumor.
A 31 year-old male patient underwent surgical treatment of the pseudoaneurysm of the ascending aorta complicating after the Bentall operation, He had undergone the replacement of the ascending aorta using the composite valved graft with direct coronary reimplantation under the diagnosis of the annuloaortic ectasia of ascending aorta associated with Marfan syndrome. Eleven months after the operation, he started to feel dyspnea and anterior chest pain, and was diagnosed as pseudoaneurysm around the ascending aortic graft. The second operation consisted of the dacron patch closure of the defect of the aortic graft which was the hole for previous coronary reimplantation, and the anastomosis between the coronary orifice and the aortic graft with the intermediate graft of a 10mm woven dacron tube, and suture closure of the fistula opening from the aneurysm. His postoperative course was uneventful and discharged without complication. He is doing well 10 months postoperatively.
