Usually in the subtotal gastrectomy, the left and the right gastric arteries, as well as the left and the right gastroepiploic arteries are ligated. Thus, to avoid a blue stomach surgeons preserve the spleen and the short gastric arteries. When a radical subtotal gastrectomy with splenectomy is performed, meticulous caution is necessary; otherwise, the subtotal gastrectomy might have to be changed to a total gastrectomy to prevent a blue stomach. We report the case of a 67-year-old woman who had distal stomach cancer with a splenic solitary mass, for which splenic meatastasis could be excluded. We planned and performed a laparoscopy-assisted radical subtotal gastrectomy with splenectomy as the diagnostic and therapeutic option. In this case, to avoid a remnant stomach infarction or total gastrectomy we saved the left gastric artery and vein with clearing perivascular soft tissue, lymphatics, and lymph nodes. Thus the radical therapeutic goal was reached, and serious complications were avoided.

Purpose: The way in which the resection margin distance for gastric cancer patients who undergo a gastric resection influences the recurrence rate, aspects of recurrence, and the prognosis according to the characteristic of the tumor is not known. We aim to find a standard for tailor-made treatment after selecting patients in this point of view who need a more sufficient resection margin. Materials and Methods: A retrospective study was done on 1,472 patients who underwent a gastrectomy due to gastric cancer at our hospital from 1992 to 2005. The median follow-up period was 37 months. Results: There were no significant differences in the recurrence rate, the aspects of recurrence, and the 5-year survival rate between early gastric cancer (EGC) patients with a resection margin distance of less than 2 cm compared with EGC patients with a resection margin distance of greater than 2 cm. However, significant differences in the survival rate were found in advanced gastric cancer (AGC) patients when the patients were classified into groups with resection margin distances less than or greater than 3 cm (P=0.02). Significant differences were noted especially in cases of diffuse histologic-type tumors located in the lower third of the stomach and in cases with Borrmann type-3 and -4 tumors. Conclusion: The distance between the tumor resection margin and the proximal gastric resection margin has no significant influence on the survival rate in EGC patients if the resection margin is negative. However, to improve a patient's survival rate, it is important to guarantee a resection margin of more than 3 cm in AGC patients, especially when the tumor is a diffuse histologic type located in the lower third of the stomach or a Borrmann type 3 and 4.

Purpose: We explored the mydriatic effects of injected intracameral epinephrine after phacoemulsification (PE) combined with phacovitrectomy to treat proliferative diabetic retinopathy (PDR). Methods: We enrolled 96 patients (96 eyes) who underwent phacovitrectomy to treat PDR; we used ImageJ software to measure pupil sizes and the ratios of pupil to cornea area (PCA) before and after PE and after pars plana vitrectomy (PPV). We compared pupil sizes between those who received intracameral epinephrine (0.001% w/v) after PE but before PPV (study group, 46 eyes) and patients not so treated (control group, 50 eyes). Results: The PCA ratios of the study group were $0.52{\pm}0.11$ before PE, $0.43{\pm}0.12$ after PE, and $0.51{\pm}0.11$ after PPV, respectively. Changes in pupil size were significant (p < 0.001, p < 0.001 respectively). The PCA ratios of the control group were $0.52{\pm}0.10$ before PE, $0.39{\pm}0.15$ after PE, and $0.43{\pm}0.15$ after PPV, respectively. Changes in pupil size after PE were significant (p = 0.011) but the change after PPV was not (p = 0.056). Conclusions: Intracameral epinephrine given after PE but before PPV effectively dilates the pupils during phacovitrectomy to treat PDR.

Purpose: To analyze the result of a repeat discectomy for ipsilateral recurrent lumbar disc herniation and to investigate the potential factors that influenced the outcomes for this surgery. Materials and Methods: Fifty-nine patients, who underwent reoperation after lumbar discectomy with a minimum follow-up period of 2 years, were reviewed. The surgical outcome was assessed using the visual analogue scale (VAS) and Macnab classification, and the recovery rate was calculated in accordance with VAS. A statistical analysis was carried out by SPSS to evaluate the possible factors that may have influenced the outcomes of the reoperation. Results: The rate of reoperation after lumbar disc surgery due to the recurrent disc herniation was 6.0% (59/983 cases). The average recovery rate of VAS from the 1st operation was approximately 77%, and from the 2nd operation was 71%. According to the Macnab criteria, the results were "excellent" or "good" in 96% of cases. Statistical analysis revealed that there was no difference of the average recovery rate (p<0.05). There is no additional instability after repeat discectomy. Factors, such as smoking, precipitating traumatic events, and diabetes mellitus did not have much influence on the average recovery rate after repeat discectomy for ipsilateral recurrent lumbar disc herniation. Conclusion: The outcomes of repeat discectomy were satisfactory. Moreover, factors, smoking, trauma history and diabetic mellitus, only had a minor impact on the outcomes of a repeat discectomy.

이 논문은 대두 이소플라본 섭취가 난소를 절제한 쥐의 골격 손실에 미치는 영향을 투여량에 따라 조사한 것이다. 실험 초기에 암컷의 Wistar rats(7개월령; n=55)을 절제 후 봉합시킨 군(SH; n=14)과 난소절제군(OVX; n=41)으로 각각 구분하여 사육하고 80일 후에 각 5마리씩을 해부하여 난소절제로 인한 골손실 진행여부를 확인하였다. 그 후 난소절제 쥐(OVX)를 9마리씩 4그룹으로 나누고 대두 이소플라본(IF, 대두단백질이 없는 실험식이에 혼합하여 공급)을 각각 0, 20, 40, 80mg/ (kg body.d)씩 84일간 공급하였다. 동시에 SH rats에게도 이소플라본이 없는 실험식이를 섭취시켰으며 164일 후에 해부하였다. 예상했던 대로 골 무기질 밀도(대퇴골, 골간부위와 골간단부위) 및 골 표면적에 대한 다공성 골 면적의 비(대퇴골 원위부 골간단에서)가 OVX군이 SH군보다 낮았다(P<0.05). OVX군은 SH군보다 혈장 osteocalcine 농도가 높았으며 소변으로의 deoxypyridinoline 배설량이 많았다(P<0.05). 164일째 osteocalcine 과 deoxypyridinoline 농도는 OVX군에서보다 IF40 및 IF80군에서 더 낮았다(P<0.05). 그럼에도 불구하고 골 무기질 밀도와 다공성 골 면적이 OVX군에서보다 IF군들에서 더 낮아지지는 않았다. 그러므로 난소를 절제한 성숙한 쥐에게 대두 이소플라본을 매일 섭취시키는 것은 골격조직의 재흡수를 감소시킬 수 있으나 이미 진행된 골감소증(osteophenia)을 회복시킬 수는 없는 것으로 나타났다.

Tooth movement facilitated by corticotomy and distraction osteogenesis, new paradigm in orthodontics, was discussed. Intrusive tooth movement of anterior or posterior teeth was thought to be difficult or impossible. In this study, a part of cortical bone, which was a sort of resistance to tooth movement in alveolar bone, was removed. On the other hand, active bone deposition was made possible in the tension side. That was the main concept of tooth movement facilitated by corticotomy and distraction osteogenesis. Teeth moved at such a speedy tate as we could not imagine in conventional tooth movement, which lead to the reduction of total treatment Period. And intrusive movement was Possible without a side effect, lot example, root resorption or the periodontal breakdown. Those were the superior aspects to the conventional orthodontics.

Ablation depth of cornea in refractive keratectomy was calculated by Munnerlyn formula. The calculations were preformed for various optical diameter (4 mm~8 mm) and various amount of corrections (-1 Dptr ~ -12 Dptr). The results to be compared with the Munnerlyn approximated formula had little effect within lower corrections, but in higher corrections > 6 Dptr can be occurred the error of 1 Dptr. Although ablation depth were evaluated, the results were only calculated by mathematical model of geometric assumptions. Because ablation depth can vary with operation conditions, the correction factor should be considered not only ablation depth by Munnerlyn formula but also surgeon-specific factor.

유두상 갑상선암의 대부분은 서서히 진행하는 양호한 임상경과를 보이나, 일부는 저등급 혹은 미분화 갑상선암으로 전환되는 생물학적 특성을 보인다. 저자는 유두상 갑상선암 환자 358예를 적용된 치료방법과 치료결과를 분석하여 논란이 되고 있는 치료방법들 중에서 적절한 치료방법을 찾고자 본 연구를 시도하였다.% 568예중 동측엽절제술 및 협부 절제술 혹은 갑상선 아전 절제술 220예, 갑상선 전 절제술 혹은 근전절제술 143예, 종양적출술 5예였고, 이중 115예는 여러가지 형태의 경부 곽청술이 추가되었고, 150예는 수술후 방사성 동위원소 치료까지 추가되었다. 또 전 환자에서 TSH 억제를 위한 갑상선 호르몬 투여를 하였다. 추적 기간은 5년에서 12년까지 평균 8.5년이었다. Cady와 Rossia AMES Scoring system에 따라 저위험군과 고위험군으로 나누어 재발율과 사망율을 산출한 결과 저위험군 255예중 재발율 11.0%, 사망율 0.4%, 고위험군 65예중 재발율 36.9%, 사망율 20.0%을 보여 고위험군에서 현격히 불량한 예후를 나타내었다. 따라서 저자들은 유두상 갑상선암의 치료방법 선택은 일률적인 치료방법 보다는 환자 개인의 임상적 특성, 병기 등을 고려하여 저위험군에서는 소극적 수술을, 고위험군에서는 적극적인 수술과 수술후 보조치료를 시행하는 것이 바람직하다고 사료되었다.

Mediastinal lymph node dissection is a method that increases the long term survival of patients with an esophageal carcinoma. However, dissection of the left mediastinal lymph node is almost impossible, as it is not easy to see. Herein, a left mediastinal lymph node dissection, with thoracoscopy through a cervical incision wound during minimal invasive esophageal surgery, is reported.
