Background The global prevalence of myelomeningocele has been reported to be 0.8-1 per 1,000 live births. Early closure of the defect is considered to be the standard of care. Various surgical methods have been reported, such as primary skin closure, local skin flaps, musculocutaneous flaps, and skin grafts. The aim of this study was to describe the clinical characteristics of myelomeningocele defects and present the surgical outcomes of recent cases of myelomeningocele at our institution. Methods Patients who underwent surgical closure of myelomeningocele at our institution from January 2004 to December 2013 were included in this study. A retrospective chart review of their medical records was performed, and comorbidities, defect size, location, surgical procedures, complications, and the final results were analyzed. Results A total of 14 patients underwent surgical closure for myelomeningocele defects. Twelve cases were closed with direct skin repair, while two cases required local skin flaps to cover the skin defects. Three cases of infection occurred, requiring incision and either drainage or removal of allogenic materials. One case of partial flap necrosis occurred, requiring secondary revision using a rotational flap and a full-thickness skin graft. Despite these complications, all wounds eventually healed completely. Conclusions Most myelomeningocele defects can be managed by direct skin repair alone. In cases of large defects, in which direct repair is not possible, local flaps may be used to cover the defect. Complications such as wound dehiscence and partial flap necrosis occurred in this study; however, all such complications were successfully managed with simple ancillary procedures.

Ketamine is a safe and effective drug for pediatric anesthesia, sedation and analgesia. We hoped to identify that surgeons could operate a pediatric hernia with the ketamine anesthesia without general anesthesia. The study was a consecutive case series of 2230 inguinal hernia patients aged 1 months to 17 years in a Joo's day-surgical clinic during 11-year period. The patients had pediatric inguinal hernia surgery without general anesthesia under the day-surgery system. We retrospectively analyzed the medical record of patients who were registered with the Diagnosis Related Group (DRG) system. All patients received ketamine (5mg/kg) and atropine (0.01mg/kg) intramuscularly before surgery. After anesthesia, we injected 1~2% lidocaine (Less than 5ml) subcutaneously at the site of incision and started operation. The surgical method was the high ligation method of the hernia sac.) In total 2230 patients, male were 1756 and female were 474. 2076 patients were a unilateral inguinal hernia at the time of surgery and 154 were bilateral hernia patients. Less than three months, depending on the age of the patients was 391, and less than 12 months the patient was 592 people (26.5%). After surgery, there were no accidents or long term complications associated with ketamine anesthesia. We think the surgeon can safely do the pediatric inguinal hernia surgery using ketamine and lidocaine without anesthesiologist through 11 years of our surgical experiences.

Background : The objective of this study was to examine the effect of management system for the appropriate prophylactic use of antibiotics in surgical patients at a tertiary hospital from 2007 to 2010. Methods : We collected clinical data of three different surgical procedures(colectomy, heart surgery, hysterectomy) for three months of 2007 and 2010, respectively. The number of total cases was 245(137, 54, 54) in 2007, 240(133, 42, 65) in 2010. We measured the rate of use of inappropriate prophylactic antibiotics, administration within 1 hour prior to the incision and the antibiotics prescription days after surgery. To evaluate the effectiveness of the management system, the results of the two groups(Group1=2007, Group2=2010) were compared by t-test, chi-square test or Fisher's exact test. Result : The rate of Aminoglycoside uses decreased drastically from 11.4% to 0.8%(P<.001). The selection of 3rd/4th Cephalosporin dropped from 11.8% to 5.8%(P=.020). The combination of antibiotics decreased from 27.8% to 11.7%(P<.001). The antibiotic prescription rate on discharge declined from 11.8% to 2.5%(P<.001) and the number of antibiotics prescription days after surgery was shortened from 4.2 days to 2.3 days(P<.001). No significant difference in the rate of administration within 1 hour between two groups was found. Through 3-year management, 5 out of 6 measures were significantly improved(except the administration within 1 hour). The rate of surgical site infection decreased from 2.4% to 1.3%(P=.504). Conclusion : The findings demonstrate that the management system for the prophylactic use of antibiotics in surgical patients was effective in decreasing the rate of surgical site infection during 3 years.

본 연구는 개에서 난소자궁절제술과 난소절제술의 실시가 동물의 통증행동과 스트레스에 미치는 영향을 비교하고, 임상적용 가능성을 평가하기 위하여 실시되었다. 13 마리의 건강한 암컷 중 (4.2-5.5 kg) 6 마리의 개에서 난소절제술이 행하여졌고, 7 마리에서 난소자궁절제술이 이루어졌다. 술 후 두 그룹 간에 수술 시간, 마취 시간, 복벽의 절개 길이를 비교하였다. 또한 술 전과 술 후 1, 2, 4, 6, 12, 24 시간째에 Short form of composite measure pain scale (CMPS-SF) 를 사용하여 통증 점수를 측정하였고 혈중 glucose 와 creatine kinase 그리고 cortisol 수치를 측정하였다. 난소자궁절제술을 시행한 그룹에서는 난소절제술을 시행한 그룹에 비해 유의적으로 (p < 0.05) 긴 수술 시간, 마취 시간, 복벽 절개 길이를 나타내었다. Two-way ANOVA test 결과 CMPS-SF에 의한 통증점수가 두 그룹 간에 유의적 (p < 0.05) 차이를 보였으며 술 후 1, 2, 4, 6 시간째 난소절제술을 행한 그룹에서 유의적으로 낮은 수치를 나타내었다. Glucose 의 경우 난소자궁절제술을 행한 그룹에서는 술 전과 비교해 유의적 (p < 0.05) 농도 증가가 술 후 1 시간째에 나타났으나 난소절제술을 행한 그룹에서는 술 후 전체 관찰기간 동안 유의적 농도 증가가 관찰 되지 않았다. Creatine Kinase 의 경우 난소자궁절제술을 행한 그룹에서는 술 전과 비교하여 술 후 1, 2, 4, 6, 12 시간째에 유의적 (p < 0.05) 농도 증가를 나타내었으나 난소절제술 그룹의 경우 술 후 4, 6, 12 시간째에만 술 전과 비교하여 유의적 (p < 0.05) 농도 증가를 나타내었다. Cortisol 의 경우 두 그룹 모두 술 후 1, 2 시간째에 유의적인 (p < 0.05) 농도 상승을 나타내었다. 본 연구 결과 난소절제술을 이용한 암캐의 중성화 수술 방법은 난소자궁절제술에 비해 짧은 복벽 절개, 수술 시간, 마취 시간을 요하며, 적은 술 후 통증과 스트레스를 유발하므로 난소절제술을 시행하는 것이 환자에게 바람직할 것으로 판단된다.

In the reconstruction of the hard tissue defect of the oral cavity, the usefulness of the chin bone graft, one of the intraoral donor site, is gradually increased. The advantages include reduced resorption rate after graft due to its membranous bone nature, relatively ease to harvest under local anesthesia, reduced operative time because of the same operative field, decreased morbidity, and relatively large amount of bone can be harvested compared to other intraoral donor site. It has also postoperative complications including paresthesia of the lip or chin area, discomfort of lower anterior teeth, and facial swelling around chin area. Of these complications, facial swelling occurs more frequently, is more severe as a early postoperative discomfort, and prevents fast recover of patient's social activity since this procedure is generally accomplished in the outpatient base under local anesthesia. So we applied a modified " gull-wing" type incision to minimize this complication, and now we report this simple but effective surgical technique with clinically favorable result.

Resection of the bowel is necessary for the repair of a ventral hernia after recovery from trauma in some cases. In such instances, polyester or polypropylene meshcannot be used due to the possibility of infection; we had to use biological mesh instead. We report a case in which a traumatic hernia was repaired with Permacol (Covidien, Norwalk, CT, USA). A 42-year-old male patient had been injured by a factory machine seven months prior to admission. At that time, he had abdominal wall injury and small bowel perforation. His abdominal wall had been a defect after operation. A CT scan of the abdomen showed that the left abdominal wall, which is lateral to left rectus abdominis muscle had only one muscle layer, an external oblique muscle, and that a previous abdominal incision had a defect along the entire incision. During the exploration, 10 cm of small bowel was removed due to firm adhesion to the previous surgical scar. Permacol mesh was applied and fixed with transfascial fixations and tacks by using the intraperitoneal onlay mesh technique. There were no complications after the surgery and the patient was discharged without any problems.

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim. A biopsy was performed by applying a direct incision after local anesthesia. Eventually, intraosseous hemangioma was diagnosed histologically. To fully resect the mass, the orbital floor and zygoma were exposed through a subciliary incision under general anesthesia, and then the tumor was completely eliminated. Bony defect was reconstructed by performing a seventh rib bone graft. Follow-up observation has so far been conducted for 10 months after surgery without recurrence or symptoms.

Background: Lidocaine patch (L5P) has demonstrated short-term efficacy in treating both acute surgical pain and chronic neuropathic pain with tolerable side effects. Percutaneous endoscopic lumbar discectomy (PELD) is the mainstay of minimally invasive spine surgery (MISS). Sufficient analgesia during PELD surgery makes the patient consider it real MISS. This study was performed to evaluate the efficacy and adverse effects of lidocaine patch in patients who underwent PELD under local anesthesia. Methods: L5P (L group) or placebo (P group) was randomly applied on the skin of the back covering the anticipated path of the working channel before 1 hour of surgery in 100 patients who underwent a single level PELD at L4-L5. Efficacy of the lidocaine patch was assessed by patient's numeric rating scale (NRS) of pain at each stage during the surgery and by a 5-scale grading of the satisfaction with the anesthesia of the operator and patients after surgery. Results: Mean NRS scores at the stages of needle insertion, skin incision, serial dilation and insertion of working channel, and subcutaneous suture were significantly lower in the L group than the P group. Postoperative operator's and patients' satisfaction scores were also significantly higher in L group than in the P group. There were subtle adverse effects in both groups. Conclusions: L5P provided better pain relief during PELD, especially at the stage of needle insertion, skin incision, serial dilation and insertion of working channel, and subcutaneous suture. It also provided higher patient and operator postoperative satisfaction, with only subtle adverse effects.

Introduction: Since 1996, Dr. James Norman has successfully performed mimimally invasive radio-guided parathyroidectomy(MIRP) using intraoperative nuclear mapping with $^{99m}Tc$ sestamibi scanning and radioactivity detection probe. Objectives: We aimed to introduce this new surgical technique and evaluate it's efficacy by our own experiences. Method: From May to October 1999, five consecutive patients with primary hyperparathyroidism underwent parathyroidectomy by using modified MIRP technique. $^{99m}Tc$ sestamibi scanning was performed 1.0 or 1.5 hour before operation. After intraoperative localization of the tumor under the guidance of quantitative gamma counting with a NEVIGATOR probe, an unilateral small skin incision(3.0-4.0cm) was placed. Without a skin flap, the strap muscle was directly divided with the use of a Harmonic scalpel. After careful dissection, the parathyroid tumor was removed. Result: In all patients, a single adenoma could be easily detected and removed by this new technique. Mean incision length was 3.2cm(3.0-4.0cm) and operative time ranged from 40 to 110minute. All the patients were discharged within 2 days of surgery without any complication. Conclusion: This new operative technique could become the most minimally invasive alternative to the standard operative procedure for parathyroid adenoma.

Various surgical techniques, such as endoscopic surgery and robotic surgery, are developed to optimize the esthetic outcome even in operations for malignancy. A modified face-lift or retroauricular approach are used to minimize postoperative scarring. Recently, robot-assisted surgery is being done in various fields and considered as favorable treatment method by many surgeons. However its high cost is a nonnegligible fraction for many patients. On the other hand, endoscopic surgery, which is cheaper than robotic surgery, is minimally invasive with contentable neck dissection. Although it is a difficult technique for a beginner surgeon due to its limited operation view, we suppose it as an alternative method for robotic surgery. Herein, we report two cases of endoscopic neck dissection via retroauricular incision with a discussion regarding the pros and cons of endoscopic neck dissection.
