The ductus arteriosus (Botallo's duct) is a vascular communication between the pulmonary artery near its bifurcation and the aorta distal to the origin of the left subclavian artery. A surgical operation was tried in the shepherd dog which was affected by patent ductus arteriosus. The patient was six months old and weighed about 11kg. Pentobarbital sodium, 26 mg/kg was used intravascularly for the anesthesia. And then a respirator was used for the patient. The thoracotomy incision was made over the fourth intercostal space on the left and the ductus arteriosus was ligated twice. But the patient revealed ventricular fibrillation at three minutes after ligations of ductus arteriosus. So the cardiac massage was done after incision of pericardium and then the defibrillator was used for the defibrillation. But the patient was not recovered without effect. It was considered that if there is complication or cyanosis, the adaptability of surgical operation should be specially considered. Histologically, chronic passive congestion of liver was observed.

A 3-year-old Thoroughbred gelding presented with left laryngeal hemiplegia with a history of laryngoplasty (tie-back surgery) failure. Postoperative endoscopy revealed no abduction or no inflammatory changes in the left arytenoid cartilage. The owner opted for the horse to undergo partial arytenoidectomy due to failed laryngoplasty. A tracheostomy tube was intubated through a mid-cervical tracheotomy to secure the airway under general anesthesia, and; laryngotomy was performed to access the arytenoid cartilage in dorsal recumbency. A partial arytenoidectomy was performed with endoscopic assistance through the left nostril, and the left arytenoid cartilage was removed, excluding the muscular process. Antibiotic and anti-inflammatory agents were administered postoperatively, and the incision site was cleaned using normal saline and antibiotic ointment twice daily. On the 12th postoperative day, endoscopy revealed redundant corniculate process mucosa at the surgical site, which was removed using rongeur forceps directly through the previous laryngotomy incision. The horse showed no significant complications during the hospitalization. Two months after surgery, the surgical site reportedly recovered with no evidence of granulation tissue. The horse returned to training and racing 3 and 7 months postoperatively, respectively. This is the first case report of a partial arytenoidectomy in a horse in South Korea. In this case, the horse returned to training after partial arytenoidectomy without significant complications, indicating that partial arytenoidectomy could be beneficial for failed laryngoplasty.

This study aimed to evaluate the feasibility of percutaneous endoscopic foraminotomy (PEF) for the treatment of intervertebral disc herniation of the thoracolumbar spine in large-breed dogs by comparing it with open hemilaminectomy (OH). Six large-breed canine cadavers were used in the present study. A barium and agarose mixture (BA-gel) simulating intervertebral disc herniation was injected into the spinal canal at two intervertebral spaces (T12-T13, L2-L3) of the thoracolumbar spine in each cadaver. PEF and OH were randomly allocated to the sites in each cadaver. Computed tomography was performed pre- and postoperatively. The incision length, vertebral window size, procedure time, and amount of simulated disc material removed were recorded to compare PEF and OH. Both procedures clearly exposed the simulated disc material and spinal cord. The size of the incision and vertebral window created after PEF was much smaller than those after OH. The surgical duration of PEF was longer than that of OH. However, no significant difference (P>0.05) was observed in the amount of BA-gel removed between PEF and OH. Thus, PEF could be used as an effective surgical option for intervertebral disc herniation of the thoracolumbar region in large-breed dogs in that it could lead to less tissue damage as well as sufficient removal of the simulated disc material.

This is the case report of huge complex odontoma treated with sagittal splitting of buccal bone plate and iliac bone graft in left mandible angle. The 22 years old patient was admitted to the department of Oral and Maxillofacial Surgery of Kyungpook National University Hospital with the chief complaint of swelling on the left mandible angle area. We used extra oral Risdon incision and splitted the buccal cortical bone after making the horizontal bone cut buccally. The tumor mass was removed with cutting into the pieces with surgical bur to prevent mandibular fracture. The dead space was grafted with autogenous iliac bone graft and the splitted buccal cortical bone was fixed with two L-type miniplate. After 12months follow up check, we noticed good process of bone healing and satisfactory aesthetic result. In this case, my operative approach provided the excellent surgical access to the hard tissue mass and minimized post operative complication comparing with the conventional surgical approaches.

Dupuytren's contracture is a condition commonly encountered by hand surgeons, although it is rare in the Asian population. Various surgical procedures for Dupuytren's contracture have been reported, and the outcomes vary according to the treatment modalities. We report the treatment results of segmental fasciectomies with multiple transverse incisions for patients with Dupuytren's contracture. The cases of seven patients who underwent multiple segmental fasciectomies with multiple transverse incisions for Dupuytren's contracture from 2006 to 2011 were reviewed retrospectively. Multiple transverse incisions to the severe contracture sites were performed initially, and additional incisions to the metacarpophalangeal (MCP) joints, and the proximal interphalangeal (PIP) joints were performed if necessary. Segmental fasciectomies by removing the fibromatous nodules or cords between the incision lines were performed and the wound margins were approximated. The mean range of motion of the involved MCP joints and PIP joints was fully recovered. During the follow-up periods, there was no evidence of recurrence or progression of disease. Multiple transverse incisions for Dupuytren's contracture are technically challenging, and require a high skill level of hand surgeons. However, we achieved excellent correction of contractures with no associated complications. Therefore, segmental fasciectomies with multiple transverse incisions can be a good treatment option for Dupuytren's contracture.

Objectives: With antibiotic resistance one of the biggest threats to global health, we report a case of surgical site infection (SSI) after breast cancer surgery that improved only with the treatment of Taglisodog-eum (托裏消毒飮), Korean herbal medicine, without the use of antibiotics. Methods: The patient diagnosed with ductal carcinoma in situ of left breast underwent nipple areola skin sparing mastectomy and reconstruction using deep inferior epigastric perforator flap. About a month later, superficial SSI occurred at the incision site of breast cancer surgery with general weakness, and Taglisodog-eum treatment was started. To evaluate the effectiveness of the treatment, we compared the infection site conditions before and after treatment. Results: About three weeks after taking Taglisodog-eum, the SSI improved along with the improvement of general weakness. Conclusions: This study shows that Taglisodog-eum may be effective for SSI after breast cancer surgery, and the potential for alternatives to reduce antibiotic use and antibiotic resistance.

Background Pincer nail deformity is a transverse overcurvature of the nail. This study aimed to define the anatomical characteristics of pincer nail deformity and to evaluate the surgical outcomes. Methods A retrospective review was conducted on 20 cases of pincer nail deformity of the great toe. Thirty subjects without pincer nail deformity or history of trauma of the feet were selected as the control group. Width and height indices were calculated, and interphalangeal angles and base widths of the distal phalanx were measured with radiography. We chose the surgical treatment methods considering perfusion-related factors such as age, diabetes mellitus, kidney disease, and peripheral vascular disease. The zigzag nail bed flap method (n=9) and the inverted T incision method (n=11) were used to repair deformities. The outcomes were evaluated 6 months after surgery. Results The interphalangeal angle was significantly greater in the preoperative patient group ($14.0^{\circ}{\pm}3.6^{\circ}$) than in the control group ($7.9^{\circ}{\pm}3.0^{\circ}$) (P<0.05). The postoperative width and height indices were very close to the measurements in the control group, and most patients were satisfied with the outcomes. Conclusions We believe that the width and height indices are useful for evaluating the deformity and outcomes of surgical treatments. We used two different surgical methods for the two patient groups with respect to the perfusion-related factors and found that the outcomes were all satisfactory. Consequently, we recommend taking into consideration the circulatory condition of the foot when deciding upon the surgical method for pincer nail deformity.
