Purpose: This study evaluated the functional and oncological outcomes of proximal gastrectomy (PG) in comparison with total gastrectomy (TG) for upper-third early gastric cancer (EGC). Materials and Methods: The medical records of upper-third EGC patients who had undergone PG (n=192) or TG (n=157) were reviewed. The PG group was further subdivided into patients who had undergone conventional open PG (cPG; n=157) or modified laparoscopy-assisted PG (mLAPG; n=35). Patients who had undergone mLAPG had a longer portion of their intra-abdominal esophagus preserved than patients who had undergone cPG. Surgical morbidity, recurrence, long-term nutritional status, and the incidence of reflux esophagitis were compared between the groups. Results: The rate of postoperative complications was significantly lower for PG than TG (16.7% vs. 31.2%), but the five-year overall survival rate was comparable between the two groups (99.3% vs. 96.3%). Postoperative levels of hemoglobin and albumin were significantly higher for patients who had undergone PG. However, the incidence of reflux esophagitis was higher for PG than for TG (37.4% vs. 3.7%; P<0.001). mLAPG was related to a lower incidence of reflux esophagitis after PG (P<0.001). Conclusions: Compared to TG, PG showed an advantage in terms of postoperative morbidity and nutrition, and there was a comparable prognosis between the two procedures. Preserving the intra-abdominal esophagus may lower the incidence of reflux esophagitis associated with PG.

Purpose: Neoadjuvant chemotherapy has been shown to improve survival in locally advanced gastric cancer, but it is associated with significant toxicity. Sarcopenia and sarcopenic obesity have been studied in several types of cancers and have been reported to be associated with higher chemotherapy toxicity and morbi-mortality. The aim of this study was to assess the prevalence of sarcopenia/sarcopenic obesity in patients with gastric cancer, as well as its association with chemotherapy toxicity and long-term outcomes. Materials and Methods: A retrospective analysis was performed using an academic cancer center patient cohort diagnosed with locally advanced gastric cancer between January 2012 and December 2014 and treated with neoadjuvant chemotherapy. We analyzed body composition (skeletal muscle and visceral fat index) in axial computed tomography images. Results: A total of 48 patients met the inclusion criteria. The mean age was $68{\pm}10years$, and 33 patients (69%) were men. Dose-limiting toxicity was observed in 22 patients (46%), and treatment was terminated early owing to toxicity in 17 patients (35%). Median follow-up was 17 months. Sarcopenia and sarcopenic obesity were found at diagnosis in 23% and 10% of patients, respectively. We observed an association between termination of chemotherapy and both sarcopenia (P=0.069) and sarcopenic obesity (P=0.004). On multivariate analysis, the odds of treatment termination were higher in patients with sarcopenia (odds ratio=4.23; P=0.050). Patients with sarcopenic obesity showed lower overall survival (median survival of 6 months [95% confidence interval {CI}=3.9-8.5] vs. 25 months [95% CI=20.2-38.2]; log-rank test P=0.000). Conclusions: Sarcopenia and sarcopenic obesity were associated with early termination of neoadjuvant chemotherapy in patients with gastric cancer; additionally, sarcopenic obesity was associated with poor survival.

Peripheral arterial disease, because of it's significant and prolonged morbidity and related mortality is a major medical and surgical problem. Contrast angiogram remains the essential standard for the anatomic demonstration of disease. It does not, however, provide data suitable for quantification or any evaluation of the microcirculation. For these reasons, radionuclide studies are playing an increasingly important role by not only confirming the diagnosis and offering objective data on the physiologic significance of anatomic lesions, but by offering prognosis of healing and prediction of therapeutic results. In addition, radionuclide procedures offer means to safely and repeatedly monitor response to therapy and long term follow up. The object of this study was to evaluate the clinical availability of $^{201}T1$ perfusion scan in patients with peripheral arterial diseases. We performed $^{201}T1$ perfusion scans in patients with five Buerger' s disease (10 legs), six DM gangrenes (12 legs) and classified three perfusion pattern groups. Finally we compared treatment modalities among each groups and compaired T1-201 perfusion scan findings with angiographic findings in six patients with Buerger's disease. The results were as follows: 1) Seven legs showed increased perfusion in stress image and normal or increased perfusion in resting image (type 1). Six legs showed decreased perfusion in stress image and improved in resting image (type II). Of total 13 legs, only 1 leg needed to amputation. 2) Three legs showed decreased perfusion in stress and resting image (type III), and subsequently all cases were received surgical amputation. 3) In six Buerger's disease patients, there were disagreements in two patients (2 legs) between $^{201}T1$ scan and angiography, in which angiograms were normal but $^{201}T1$ scans showed 'type II' perfusion patterns.

Background: Cardiac involvement of Behcets disease is very rate, however, the prognosis of Behcet disease depends on cardiovascular complications. In this article, we described surgical treatment of aortic insufficiency with Behcets disease. Material and Method: From March 1986 to February 1998, we operated on 10 patients of aortic insufficiency with Behcets disease. Male to female ratio was 8 to 2, and age ranged from 21 to 40 years(mean 32.8 years). There were 8 patients with evidence of Behcets disease and another 2 patients had some suspicious findings of Behcets disease(i.e., prosthetic value dehiscence, hypertrophied aortic wall). Adequate preoperative medical treatment for Behcets disease was done in 3 patients. Result: We performed 24 open heart surgeries in 10 patients. Redo value replacements using prosthetic valves were done in 4 patients. Among them, 2 patients were operated on for a second redo valve replacement and one of them operated on for a 4th and 5th operation because of recurrent paravalvular leakage. These 4 patients expired. 1 patient who had undergons tissue value replacement is alive. 1 patient who underwent Cabrol operation expired dut to rupture of graft anastomosis site. We used homografts in 3 patients. In 2 of them, we performed aortic root replacement and subcoronary valve replacement in another patient. The patient who underwent subcoronary valve insertion had remnant aortic insufficiency, so we are closely observing him. We also performed Ross operation in a 24 year old female who suffered severs aortic insufficiency and endocarditis after aortic valvuloplasty. 5 patients are alive and mean follow up duration is 49.0 months. Among them, we used homografts or sutografts in 4 patients. We could observe excellent clinical results in the patients who underwent aortic root replacement using homograft and they were treated medically for Behcets disease. Conclusion: We concluded that adequate preporative diagnosis, clinical suspicion, and periopertive medical treatment for Behcets disease are very important for the result of surgical management of aortic insufficiency with Behcets disease. The use of homograft or autograft was helpful for the healing of anastomosis site and we should carefully observe the long term follow up results.

Stress is experienced when a person tries to maintain stability in the face of life change but is not able to meet the adaptive demands of change. This can be especially true for the parents who has a cerebral palsy childs who needs long term rare, where parents, are the primary source of care and responsibility. Successful coping leads to maintenance of the parents role and this has an effect on the health status of the child. This descriptive study was attempted to identify stress factors, levels and helpful coping patterns for parents who must take care of cerebral palsy children. Data were collected from 43 subjects who were parents of children diagnosed with cerebral palsy The informations gathered from March 25, 1994 to April 14, 1994 by means of structured questionnaires were analyzed. Two instruments were used to collect the data 1) Lee's stress questionnaire consisted of 33 stress factors and measured by four point Likert scale. 2) Modified Chronic Health Inventory for parents: The modified CHIP included 43 items of coping methods with four point Likert scale. The results of this study were as follows: 1) Stress items could have a maximum score of three points, for a total possible score of 132 points. The mean score for the total was 92.02 points. The item mean score was 2.85 points showing that the parents were experiencing moderate to much stress. 2) The items with the highest stress items were 16 items. The stress items with the lowest mean scores were 10 items. 3) Of the stress categories: The highest stress category was related to changes in the illness status of the child and difficulty in taking rare of the child. The second stressful category was related to the prognosis of the child's condition. The least stress was noticed to social-personal relationships and the responsibility of the care givers. 4) Items measuring coping in the parents had a maximum score of three points each with a total possible roping score of 172 points. The mean score for the total was 103,9 paints. The item mean score was 2.42 points indicating that there were responses of little helpful to moderately helpful on each coping pattern. 5) The most helpful coping items were 7 items. The least helpful coping items were 2 items. 6) Effectiveness of the coping for each patterns was examined : Understanding the illness condition from communication with parents of children with the same condition and consultation with the medical team was the most helpful coping pattern. Family's coorperation and integration and optimism were a moderately helpful coping pattern. Social support psychological stability and self esteem were the least helpful toping pattern. In conclusion, the highest stress for parents of children with cerebropalsy was found to be very stressful changes in the illness of the child and to taking care of a child who is suffering. The parents were helped by the coping methods using understanding of the illness condition through consultation with the medical learn and communication with parents in the same situation. Based on the knowledge, care could develop intervention strategies appropriate for them, help them to develop their effective coping patterns, and give support them in the process of coping with their stress.

Background: The Ki-67 protein is a biomarker associated with cell proliferation and a valuable negative prognostic factor in non-small cell lung cancer. We investigated the Ki-67 protein expression in resected non-small cell lung cancer to evaluate the impact on clinicopathological characteristics and postoperative prognosis. Material and Method: Using monoclonal antibody Ki-67, we immunohistochemically examined 38 surgically resected non-small ceil lung cancers to determine Ki-67 Labeling Index (LI). We analysed the differences of clinicopathological characteristics and postoperative recurrence and survival between High Ki-67 Group $(LI{\ge}20%)$ and Low Ki-67 Group (LI<20%). Result: The Ki-67 LIs were heterogenous and a mean values was $20.0{\pm}20.05%$. There were no significant differences in age, sex, smoking, TNM stage, and vascular invasion between High Ki-67 Group and Low Ki-67 Group. A High Ki-67 Group was significantly associated with squamous cell type, poor differentiation, and lymphatic invasion $(p{\le}0.05)$. High Ki-67 Group showed a trend of lower survival (median 47.2 vs. 90.5 months, p=0.312) and lower disease-free survival (median 18.2 vs. 72.3 months, p=0.327) than Low Ki-67 Group. Conclusion: These results indicate that increased Ki-67 protein expression may be a negative prognostic factor and showed a trend of shortened survival and disease-free survival. To evaluate the pivotal role of Ki-67 protein expression, a long-term follow-up and further study are required.

Korea is an endemic area of chronic hepatitis in the world. Liver cirrhosis and liver cell carcinoma, presumed to be related to such chronic hepatitis, are the major causes of death in this country. The purpose of this study is disclosing the sources of chronic hepatitis in Korea establishing its histologic characteristics, disclosing the patterns of progression in chronic hepatitis, delineating its prognosis and finally speculating its etiology. The study group was composed of 183 patients with biopsy-proven acute icteric viral hepaticis, 32 patients with biopsy- proven anicteric hepatitis and 260 patients with biopsy- proven chronic hepatitis. These patients submitted to long-term follow-up by means of liver needle biopsy and/or clinicolaboratory evaluation. The period of follow-up ranged from two months to 18 years. The histological features of the initial biopsy specimens of chronic hepatitis permitted a division of the cases cases into the following five types: Type I. Persisting portal hepatitis : so called persisting hepatitis 43 Type II. Chronic inactive hepatitis with incomplete strand septal fibrosis. This type has thin fibrotic septation in addition to Type I with portal sclerosis 38 Type III. Chronic active periportal hepatitis(CAPH) : so called aggressive hepatitis, characterized by marked piecemeal necrosis. This type has been subdivided further into three groups: AB and C on the basis of histologic features. A CAPH without cirrhosis 15 B CAPH with cirrhosis 99 C CAPH with diffuse acinus type parenchymal nodules; characterized by rosette-forming micronodules 21 Type IV. Subacute hepatic necrosis; characterized by multilobular and/or bridging necrosis. 14 Type V. Persisting lobular hepatitis; characterized by spotty necrosis, which looks very similar to acute viral hepatitis. Such histologic changes should be persisted for more than six months 30 In Korea the main source of chronic hepatitis is the anicteric type. Of the chronic hepatitis observed in the hospital, Type IIIb was the most frequent in its incidence and occasionally exhibited development of hepatocellular carcinoma, but the mortality was highest in Type IIIc during the period of follow-up. Histologic characteristics of these five types suggest a spectrum of chronic hepatitis in Korea from an early and mild stage to advanced and fatal cirrhosis, which is occasionally associated with primary hepatic cell carcinoma. It seems that Type IV can be followed by flare-up of various stages of acute and chronic hepatitis with HBsAg and that many cases of liver cirrhosis prevalent in Korea occur through such an active process of Type IV. The etiology is not established, but in Korea it is mainly related to HBsAg.

Background: To evaluate efficacy and side effects of glycididazole sodium (CMNa) combined with chemotherapy (cisplatin plus 5-FU/folic acid, PLF) and radiotherapy in treating patients with locally advanced nasopharyngeal carcinoma. Materials and Methods: Patients with III~IV stage nasopharyngeal carcinoma (NPC),were randomly divided into treatment group (46 patients) and control group (45 patients). Both groups received radiotherapy concomitant with PLF chemotherapy. The treatment group at the same time cwas given CMNa ($800mg/m^2$ before radiotherapy), by l h intravenous drip, three times a week. Results: When the dose of radiation was over 60 Gy, complete response rates of nasopharyngeal tumor and lymph node metastases in treatment group were significantly higher than in the control group (93.5% vs 77.8%; 89.1% vs 93.5%, p<0.05). Three months after radiotherapy, complete response rate of nasopharynx cancer and lymph node metastases in treatment group was both 97.8%, again higher than in the control group (84.4% and 82.2%) (p<0.05). In the treatment group, 1, 3, 5 year disease-free survival rates were 95.7%, 86.7% and 54.5%; and in control group, the corresponding disease-free survival rates were 93.3%, 66.2% and 38.6%, respectively, the difference being statistically significant (log-rank =5.887, p=0.015). One, 3, 5 year overall survival rates in two groups of patients were 97.8%, 93.5%, 70.4% and 95.5%, 88.07%, 48.4%, respectively, again with a statistically significant difference (log-rank=6.470, p=0.011). Acute toxicity and long-term radiotherapy related toxicity in the two groups did not differ (p>0.05). Conclusions: Glycididazole sodium could improve curative effects without increasing adverse reactions when treating paitents with locally advanced nasopharyngeal carcinoma.

Objective : Paraclinoid aneurysms are a group of aneurysms arising at the distal internal carotid artery. Due to a high incidence of small, wide-necked aneurysms in this zone, it is often challenging to achieve complete occlusion when solely using detachable coils, thus stent placement is often required. In the present study, we aimed to investigate the effect of stent placement in endovascular treatment of paraclinoid aneurysms. Methods : Data of 98 paraclinoid aneurysms treated by endovascular approach in our center from August 2005 to June 2016 were retrospectively reviewed. They were divided into two groups : simple coiling and stent-assisted coiling. Differences in the recurrence and progressive occlusion between the two groups were mainly analyzed. The recurrence was defined as more than one grade worsening according to Raymond-Roy Classification or major recanalization that is large enough to permit retreatment in the follow-up study compared to the immediate post-operative results. Results : Complete occlusion was achieved immediately after endovascular treatment in eight out of 37 patients (21.6%) in the stent-assisted group and 18 out of 61 (29.5%) in the simple coiling group. In the follow-up imaging studies, the recurrence rate was lower in the stent-assisted group (one out of 37, 2.7%) compared to the simple coiling group (13 out of 61, 21.3%) (p=0.011). Multivariate logistic regression model showed lower recurrence rate in the stent-assisted group than the simple coiling group (odds ratio [OR] 0.051, 95% confidence interval [CI] 0.005-0.527). Furthermore there was also a significant difference in the rate of progressive occlusion between the stent-assisted group (16 out of 29 patients, 55.2%) and the simple coiling group (10 out of 43 patients, 23.3%) (p=0.006). The stent-assisted group also exhibited a higher rate of progressive occlusion than the simple coiling group in the multivariate logistic regression model (OR 3.208, 95% CI 1.106-9.302). Conclusion : Use of stents results in good prognosis not only by reducing the recurrence rate but also by increasing the rate of progressive occlusion in wide-necked paraclinoid aneurysms. Stent-assisted coil embolization can be an important treatment strategy for paraclinoid aneurysms when considering the superiority of long term outcome.

A 16-year-old female Shih-Tzu, weighing 5 kg, presented with clinical symptoms of abdominal distension and urinary and fecal incontinence. Abdominal palpation detected a large mass. According to the radiographic findings, the bladder had been moved to the umbilicus by the mass and a large abdominal mass was confirmed in the lower abdominal area. Ultrasonography indentified a large heterogeneous mass with heterogeneous parenchyma and a focal anechoic area in the lower abdominal area. The complete blood count abnormalities suggested thrombocytosis and mild neutrophilia, and the serum chemistry indicated an elevated alkaline phosphatase value. During laparotomy, a firm mass that measured $10.5{\times}9.6cm$ was found between the uterine cervix and urinary bladder. The urethra was embedded in the mass. A diagnosis of leiomyosarcoma was established based on histopathology and histochemistry. One week after surgery, urinary retention symptoms that did not appear to be related to mechanical obstruction presented suddenly, but they did not respond to several drug treatments, thus long-term conservative therapy was adopted. The urinary symptoms disappeared on day 27 and the patient started to void large quantities of urine in a smooth and frequent manner. This case report describes the serial changes in the patient's status and the response after surgical remove of the urethra embedding leiomyosarcoma.
