Rupture of the main bronchus due to blunt chest trauma is very rare, especially In childhood although the incidence is increasing. Early diagnosis and primary repair not. only restore normal lung function but also avoid the difficulties and complications associated with delayed diagnosis and repair. We experienced 2 cases of right main bronchial rupture caused by traffic accidents. Patients suffered from progressively developing dyspnea and subcutaneous emphysema on the neck, anteriorchest,andanteriorabdominalwall. Emergency operations were performed through right posterolateral thoracotomy incision at the 4th intercostal space. Intraoperatively, the right main bronchus completely transsected and separated. Corrective bronchoplasty was performed with end-to-end anastomosis using interrupted suture with 3-0 Vicryle and the suture line was reinforced with azygos vein and parietal pleural flap. Postoperative courses were uneventful and patients discharged without any specific pro lems.

Biological safety, physico-chemical and microbiological experiments were carried out in order to study the possibility of radiation sterilization on medical products, such as polyethylene and polystyrene bottles, gauze sponges and surgical silk suture. Results are as follows: 1. Biological test on plastic samples as to acute systemic toxicity, eye irritation, skin irritation, pyrogen, haemolysis showed satisfactory results. But physico-chemically, the oxidizable matter, nonvolatile residues, residue on ignition seemed to be increased slightly in irradiated samples, though the experimental results were within the range of U.S.P. 19, N.F. and K.P. III. 2. After irradiation, both plastic and gauze sponges showed considerable decrease in pH. 3. Most medical products were sterilized by 1.5 Mard. For the sterilization of the suigical silk suture, 4.5 Mrad is required dul to its radiation resistant micro-organisms. 4. Biologically, total dose of 2.5 Mrad was safe enough to sterilize the medical products, and physico-chemically the results are acceptable according to U.S.P. 19 and K.P. III. However, better results may be expected when the quality of material and additives are improved.

The objective of this study was to compare the total surgical time, pain score and hemorrhage after ovariohysterectomy (OVH) and bilateral flank ovariectomy (BFOVE) with hemoclips in dogs. OVH was operated on six dogs and BFOVE was performed on six dogs. In BFOVE group, both ovarian pedicle hemostasis applied using hemoclips after removing ovaries. Total surgical time was recorded from starting incision of skin to closure last skin suture. Pain score was measured at 2, 6, 12, and 24 hours after surgery based on University of Melbourne Pain Scale (UMPS). Hemorrhage around clipping area, uterus, abdominal muscles, and skin were monitored after surgery. BFOVE technique could reduce total surgical time and pain after surgery. There was no hemorrhagic problems near ovarian pedicles following surgery. BFOVE with hemoclips could be useful and recommended for sterilization in dog.

Twenty one cows in Goyang and Paju cities were referred due to displacement of the abomasum and foreign body in the rumen. Omentopexy and rumenotomy through a right flank celiotomy were performed for treatment of abomasal displacement and the foreign body removal in the rumen. The right paralumbar fossa is clipped and prepared surgically. Local anesthesia is instituted by performing inverted L block. The abdomen was entered through 25 to 30 cm vertical incision in the right paralumbar fossa starting 4 to 5 cm ventral to the transverse processes of the lumbar vertebrae. A 14-gauge needle with rubber tubing attached is inserted to relieve the gaseous pressure and to facilitate further exploration and manipulation. The rumen was gently pulled out of the abdominal cavity and incision was made at the omentum. Rumenotomy was done and retrieved the foreign body. After the rumen was rinsed with sterile saline, the rumen wall was closed by a Lembert suture technique. The omentum was closed by a simple continuous suture. Right flank omentopexy was performed for the surgical correction of abomasal displacement. Recovery results among 21 cows included 9 excellent, 5 good, 2 fair and 5 bad. It was considered that operation of abomasal displacement and foreign body removal in the rumen through right flank celiotomy was a good surgical technique to reduce expenses, surgical pain, and surgery time.

목적: Bankart병변에서 봉합나사못을 이용한 관절경적 치료는 관절와 가장자리에 점고정(point fixation)을 하여, 관절와 골 결손시에 적절한 부착부 족문(foot print)치유를 이루지 못한다는 한계점이 있다. 이에 본 저자들은 골성 Bankart병변에서 나사못 고정으로 인한 점접촉의 단점을 피하고 관절순의 교차압박을 통해 기계적 안정성을 개선시킬수 있는 경골-유사 교량형 봉합술식을 소개하고자 한다. 수술 술기: 본 술식은 교량형 봉합술식을 통한 경 골-유사 회전근개 봉합술에서 응용되었으며, 이는 부착부 족문과 건 사이 평균압력과 압력이 가해지는 접촉면적을 개선시킨다. 골성 Bankart 병변의 경우 관절와 부착부의 돌출된 골병변은 제거하거나 다듬어주며, 골편이 가동성이 있는 경우 관절순과 함께 분리시킨다. 이후 2개의 나사못(3.0 mm Biofastak, $Arthrex^{(R)}$, Naples, FL)을 골성 Bankart병변 위, 아래 부위의 내측 연에 삽입한다. 관절와를 적당한 두께로 덮을수 있도록 하 상완관절와인대 부근 관절낭순의 내측에 봉합갈고리를 이용하여 봉합사를 각각 통과시켜 mattress봉합을 시행한다. 교량형 봉합을 위해서, 전방 관절와연의 관절측 가장자리에 3.5 mm pushloc 나사못 ($Arthrex^{(R)}$, Naples, FL) 구멍을 만든 후 먼저 원위 교량형 봉합을 시행하고, 이어 근위 교량형 봉합을 시행함으로써 근위방향으로 관절순을 가동시킬 수 있다. 본 술식은 나사못 고정으로 인한 점 접촉의 기술적 단점을 피하고 관절순 교차압박을 통해 간격형성을 감소시킬수 있는 이점이 있다.

Purpose: Facial rejuvenating surgery has become a challenge to most plastic surgeons. Patients are demanding fewer complications, a prompt recovery, and more natural results. Current trend of the face lift surgery has been developed into less invasive procedures. Every aging patient in Asia wants to look younger without obvious evidence of surgical correction. Methods: The authors performed the limited dissection face lift with PDS quilting suture on twenty five patients. These five quilting sutures consist of sutures at 1~2 cm posterior to the prominent point of zygoma to the periosteum of the zygomatic arch, at the lateral border of Bichat's fat pad area to the zygomatic arch, at the lateral border of the orbicularis oculi muscle to the deep temporal fascia, at the upper lateral border of the platysma to the periosteum of the mastoid, and at the anterior lower margin of the earlobe to the deep temporal fascia by quilting suture technique to achieve rejuvenation. Results: These procedures could produce a balanced volumetric rejuvenation. This method gave considerable benefit of stable and satisfactory results. It provides reduced operative time, well corrected nasolabial fold and neck wrinkle, and swift recovery with minimal complications. Conclusion: Although it could not replace the classic facelift, this technique can be recommended as an option for patients who do not present with advanced facial aging or not want a more extensive procedure.

Objective : Cerebrospinal fluid leakage related complications (CLC) occasionally occur after intradural spinal surgery. We sought to investigate the effectiveness of early ambulation after intradural spinal surgery and analyze the risk factors for CLC. Methods : For this retrospective cohort study, we enrolled 314 patients who underwent intradural spinal surgery at a single institution. The early group contained 79 patients who started ambulation after 1 day of bedrest without position restrictions, while the late group consisted of 235 patients who started ambulation after at least 3 days of bed rest and were limited to the prone position after surgery. In the early group, Prolene 6-0 was used as the dura suture material, while black silk 5-0 was used as the dura suture material in the late group. Results : The overall incidence rate of CLC was 10.8%. Significant differences between the early and late groups were identified in the rate of CLC (2.5% vs. 13.6%), surgical repair required (1.3% vs. 7.7%), and length of hospital stay (2.99 vs. 9.29 days) (p<0.05). Logistic regression analysis revealed that CLC was associated with practices specific to the late group (p=0.011) and the revision surgery (p=0.022). Conclusion : Using Prolene 6-0 as a dura suture material for intradural spinal surgery resulted in lower CLC rates compared to black silk 5-0 sutures despite a shorter bed rest period. Our findings revealed that suture - needle ratio related to dura defect was the most critical factor for CLC. One-day ambulation after primary dura closure using Prolene 6-0 sutures appears to be a costeffective and safe strategy for intradural spinal surgery.
