배경: 기관지내결핵에 의한 주기관지협착에 대하여 주기관지재건술은 전폐절제술을 피하고 폐실질을 보존할 수 있는 방법이지만 그 위험성 때문에 비침습적인 중재치료가 주를 이루고 있다. 하지만, 적절한 치료가 이루어지고 있는가에 대해서는 논란의 여지가 많다. 본원에서는 지난 10년 간 주기관지재건술을 시행하였고 이후 임상적 경과를 토대로 수술의 성적을 조사, 분석하여 결핵성 주기관지협착에 대한 주기관지재건술의 위험성과 효용성을 판단하고자 한다. 대상 및 방법: 지난 10년 간 결핵성 주기관지협착으로 인해 주기관지재건술을 시행받은 21명의 환자를 대상으로 각 환자들의 임상기록과 외래추적 기록을 통하여 후향적 연구를 하였다. 모든 환자에서 항결핵약제를 복용한 과거력이 있었으며, 기관지내시경 및 흉부전산화단층촬영을 통해 수술 전 평가를 하였다. 결과: 수술로 인한 사망은 없었으며 중증의 합병증도 발생하지 않았다. 단지 두 명의 환자에서 효과적인 객담배출이 이루어지지 않아 치료적 기관지내시경과 기관내삽관을 시행하였다. 모든 환자들은 현재까지 기도폐쇄의 증상 없이 생존해 있다. 걸론: 기관지내결핵으로 인한 주기관지협착에 대해 해부학적으로 용이한 조건에서의 주기관지재건술은 치료에 있어서 초치료의 일환으로 고려해야 한다.

Objective : The increasing use of sensitive neuroimaging techniques has demonstrated that significant percentage of patients with intractable complex partial seizures have brain masses, especially in temporal lobe. The optimal surgical solution for these patients is still open to debate. The purpose of our investigation is to evaluate the surgical outcome of patient with lesion-related temporal lobe epilepsy with respect to the types of surgery and the location of lesion. Patients and Methods : From DEC. 1993 to Dec. 1997, 35 patients with intractable epilepsy and space occupying temporal lobe lesion identified in preoperative MRI were included in this study. The types of surgery were lesionectomy, anterior temporal lobectomy with or without hippocampectomy. The location of lesion was divided as anteromedial group and lateral cortical group. The postoperative seizure outcomes according to the type of surgery and location of the lesion were compared. Results : Twenty-six of 34 patients(76.5%) were seizure-free after surgery. The Engel's class was favorable after anterior temporal lobectomy with or without hippocampectomy(p=.044) Conclusion : It is favorable to perform anterior temporal lobectomy for the treatment of intractable epilepsy with space-occipying lesion in temporal lobe. The resection of the hippocampus can be individualized.

Objectives : In general, conventional T2, T3 thoracoscopic sympathicotomy must be one of the most effective treatments for the essential palmar hyperhidrosis. However, this is offset by the occurrence of a high rate of side effects, such as embarrassing compensatory sweating and Hornor's syndrome. The authors have performed a selective T3 thoracoscopic sympathicotomy to our patients to see whether it provides successful results with less side effects. Its preliminary results were compared with those of conventional T2, T3 thoracoscopic sympathicotomy. Methods : The thoracoscopic sympathicotomy was performed in 54 patients suffering from essential palmar hyperhidrosis. Twenty-four patients underwent a conventional sympathicotmy(group A) from Jan 1997 to Dec 1997 and 30 patients a selective T3 sympathicotmy(group B) from Jan 1998 to Dec 1999. For assessment of postoperative success and of complications all patients charts were reviewed. Patients further received a postal questionnaire regarding long-term effect, satisfaction, and side-effects. Results : No recurrence was observed in both groups. The global rate of compensatory sweating was significantly(p ＝0.020) different in both groups : 11 patients(45.8%) in group A and 5 patients(16.73%) in group B. The Hornor's syndrome was observed only in 4 patients in group A. The preliminary results of the procedure in group A were considered fully-satisfying by 16 patients(66.6%), 6 patients(25%) were satisfied partially, and only 2 patients(8.3%) were dissatisfied, and those of the procedure in group B satisfying by 26 patients(86.6%), 4 patients(13.3.% ) were satisfied partially, and none dissatisfied. Conclusion : The selective T3 sympathicotomy results in a significant decrease in the rate of disturbing side effects comparing to conventional T2, T3 sympathicotomy and it dose not lead to recurrence. Our results contribute to recommendations of a selective T3 thoracoscopic sympathicotomy as treatment of choice in essential palmar hyperhidrosis.

Purpose: Cervical necrotizing fasciitis tends to involve the deep soft tissues and spread caudally to the anterior chest and mediastinum, often resulting in major complications and death. It may rapidly spread into the thorax along fascial planes, and the associated diagnostic delay results in this descending necrotizing mediastinitis. So, aggressive multidisciplinary therapy with surgical drainage is mandatory. We present a very rare case of descending necrotizing mediastinitis with literature review. Methods: A 53 years old male visited our department 7 days after trauma in neck. His premorbid conditions and risk factors of necrotizing fasciitis were concealed hepatoma, trauma history, chronic liver disease, and nutrition deficit. Computed tomographic scans of the head and neck region were performed in this patient : signs of necrotizing fasciitis, were seen in the platysma, sternocleidomastoid, trapezius muscle and strap muscles of the neck. Fluid accumulations involved multiple neck spaces and mediastinum. At the time, he diagnosed as necrotizing fasciitis on his neck and anterior chest. Necrotic wound was excised serially and we treated this with the Vacuum - assisted closure(VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge and achieving additional 3 pieces drainage tubes in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, abscess drainage with the VAC system, and then split thickness skin graft. The postoperative course was uneventful. Conclusion: The refined technique using the VAC system can provide a means of simple and effective management for the descending necrotizing mediastinitis, with better cosmetic and functional results. Finally, the VAC system has been adopted as the standard treatment for deep cervical and mediastinal wound infections as a result of the excellent clinical outcome.

Purpose: The wound of a patient who has chronic venous insufficiency is easy to recur. Also they develop a complication even after the conservative therapy or skin graft. We have to diagnose the venous stasis ulcer correctly and remove the cause to improve the effectiveness of treatment. We operated endoscopic perforating vein ligation and splitt thickness skin graft on a patient with venous stasis ulceration on right leg. Methods: A 26 year old male patient who had a scalding burn on his right leg in July 2005 checked into our hospital in March 2008. Even though he got three operations - the split thickness skin graft - at different clinics, the wound did not heal. The size of the wound was 12 by $8cm^2$ and granulation with edema and fibrosis had been formed. We kept observation on many collateral vessels and perforating vein through venogram and doppler sonography and firmly get to know that the wound came with chronic venous insufficiency. After a debridement and an application of VAC$^{(R)}$ for two weeks, the condition of granulation got better. So we proceeded with the operation using subfascial endoscopic perforating surgery and split thickness skin graft. Results: Through the venogram after the operation, we found out that the collateral vessels had been reduced compared to the previous condition and the widened perforating vein disappeared. During a follow up of 6 months, the patient did not develop recurrent stasis ulcer and postoperative complications. Conclusion: Subfascial endoscopic perforator ligation is relatively simple technique with a low complication rate and recurrence rate. Split thickness skin graft with subfascial endoscopic perforator surgery can be valuable method for treating severe venous stasis ulcers.

Purpose: Sensory changes in the upper limb are complications of a mastectomy with immediate breast reconstruction with the treatment of breast cancer. The purpose of this study is to clarify whether immediate breast reconstruction worsens the sensory changes. Methods: From March 2004 to December 2005, 20 patients who had a mastectomy with immediate breast reconstruction(reconstruction group) were compared with 23 patients who had a mastectomy alone(control group). All patients had stage I or II breast cancer. The sensory changes were assessed in a blind manner by one examiner that used light touch sensation, static two-point discrimination, pain, vibration, hot and cold temperature perception. The sensory changes were identified along the sensory dermatome for diagnosing the damaged nerves. The following factors and their relationship with the sensory changes were analyzed : age, complications, and the mastectomy method. Results: There was no statistical difference in the static two-point discrimination, pain, vibration, hot and cold temperature perception between the two groups. However, the ability to recognize light touch was significantly better(p=0.045) in the reconstruction group than in the control group. The main site of sensory change was the proximal and medial portion of the upper limb in both groups. At these sites, the mean value of Semmes-Weinstein monofilament was $1.01g/mm^2$(reconstruction group 0.82, control group 1.17) and 2-point discrimination was 51.74(converted to perfect score of 100; reconstruction group 42.50, control group 59.78). The total rate of early complications was found to be significantly lower(p=0.006) in the reconstruction group than in the control group. Conclusion: These findings suggest that an immediate breast reconstructive procedure following a mastectomy is as safe as or safer than a mastectomy alone with respect to postoperative sensory changes of the ipsilateral upper limb.

Background : An area of the skull exposed by burn injury has been covered by various methods including local flap, skin graft, or free flap surgery. Each method has disadvantages, such as postoperative alopecia or donor site morbidities. Due to the risk of osteomyelitis in the injured skull during the expansion period, tissue expansion was excluded from primary reconstruction. However, successful primary reconstruction was possible in burned skull by tissue expansion. Methods : From January 2000 to 2011, tissue expansion surgery was performed on 10 patients who had sustained electrical burn injuries. In the 3 initial cases, removal of the injured part of the skull and a bone graft was performed. In the latter 7 cases, the injured skull tissue was preserved and covered with a scalp flap directly to obtain natural bone healing and bone remodeling. Results : The mean age of patients was $49.9{\pm}12.2$ years, with 8 male and 2 female. The size of the burn wound was an average of $119.6{\pm}36.7cm^2$. The mean expansion duration was $65.5{\pm}5.6$ days, and the inflation volume was an average of $615{\pm}197.6mL$. Mean defect size was $122.2{\pm}34.9cm^2$. The complications including infection, hematoma, and the exposure of the expander were observed in 4 cases. Nonetheless, only 1 case required revision. Conclusions : Successful coverage was performed by tissue expansion surgery in burned skull primarily and no secondary reconstruction was needed. Although the risks of osteomyelitis during the expansion period were present, constant coverage of the injured skull and active wound treatment helped successful primary reconstruction of burned skull by tissue expansion.
