The occurrence of hiatal hernia after total gastrectomy with Roux-en-Y reconstruction is rare. We report the case of a 76-year-old man who presented with dyspnea, vomiting, and fever around 8 days after total gastrectomy with Roux-en-Y reconstruction. Abdominal computed tomography revealed a hiatal hernia containing part of the small intestine in the left thoracic cavity. Emergent reduction and repair of the hiatal hernia were performed later. Operative findings revealed that the Roux limb was incarcerated in the left pleural cavity. Esophagojejunostomy leakage, perforation of the small intestine with transient ischemic change, and pyothorax were also found. Thus, feeding jejunostomy, thoracoscopic decortication, and diversion T-tube esophagostomy were performed. Considering that the main cause of hiatal hernia is blunt dissection with division of the phrenoesophageal membrane, approximating the crus with 1 or 2 figure-8 sutures, according to the size of the defect, to prevent the incidence of hiatal hernia after total gastrectomy may be performed.

Purpose: With advances in surgical techniques, reduced-port laparoscopic surgery is increasingly being performed for the treatment of gastric carcinoma. Many studies have reported satisfactory short-term outcomes after reduced 3-port laparoscopic gastrectomy (LG). The aim of this study was to investigate the long-term oncological outcomes of 3-port LG in patients with gastric carcinoma. Materials and Methods: We reviewed the medical records of 1,117 patients who underwent LG for gastric carcinoma in three major institutions between 2012 and 2015. The data showed that 460 patients underwent 3-port LG without assistance, and 657 underwent conventional 5-port LG. We compared the overall and disease-free survival rates between the 2 groups. Results: There were 642 male and 475 female patients with a mean age of 56.1 years. Among them, 1,028 (92.0%) underwent distal gastrectomy and 89 (8.0%) underwent total gastrectomy. In the final pathologic examination, 1,027 patients (91.9%) were stage I, 73 (6.5%) were stage II, and 17 (1.5%) were stage III, and there were no significant difference in the pathologic stage between groups. The 3- and 5-port LG groups showed no significant differences in the 5-year overall survival (94.3% vs. 96.7%, P=0.138) or disease-free survival (94.3% vs. 95.9%, P=0.231). Stratified analyses according to pT and pN stages also showed no significant differences in overall or disease-free survival between the two groups. Conclusions: Long-term survival after 3- and 5-port LG was comparable in patients with early-stage gastric carcinoma. The 3-port technique requiring limited surgical assistance may be an appropriate surgical option for this patient population.

Objectives : Cancer patients who are afraid of unpleasant therapy and doubt a perfect cure often seek out traditional Korean medicine or many other kinds of complementary and alterative medicine (CAM) instead. This study was carried out in order to learn the prevalence and kinds of the traditional Korean medicine and CAM to evaluate awareness of and attitude toward it. Methods : 213 patients with gastric cancer who had undergone surgery in the department of gastrointestinal surgery and visited for routine follow-up from November to December of 2004 were included. A questionnaire survey was done by trained interviewers for CAM and demographic information. Results : 96.7% of patients had experience with CAM. The kinds and frequencies of CAM were diet and nutrition 21.0%, folk remedy 21.0%, pharmacological treatment 13.5%, oriental medicine 5.3% and mind-body intervention 1.4%. 56.8% of patients had experienced 2-6 kinds of CAM, 37.4% more than 7. Among diet and nutrition, ginseng (62.9%) was highest, followed by ox leg bone soup (50.8%) and pumpkin (31.5%). Among the folk remedies, elm tree was highest at 46.5%, followed by phellinus linteus (Sang-Whang) at 26.8% and ganoderma lucidum (Young-Gee) 20.7%.satisfaction with CAM was relatively low (43.2%), many patients (78.2%) replied that they would use it continuously. Conclusion : Most patients had experience with many kinds of CAM, but didn't discuss it with medical doctors. If scientific study proves whether or not each kind of CAM is actually effective ondisease, it will help to improve the health of patients and prevent the inappropriate usage and cost.

Conjugated linoleic acid (CLA) is a group of positional and geometric isomers of linoleic acid that have been used to reduce the incidence, growth and metastasis of breast, colon, prostate and gastric cancer in animals. CLA could reduce tumor growth by altering angiogenesis; a process requiring associated angiogenic factors such as vascular endothelial growth factor (VEGF). In this study, we determined whether CLA could modulate the expression of VEGF in murine mammary tumor cells and adipocytes. The c9, t11-CLA isomer reduced VEGF transcripts and protein when mammary tumor cells were stimulated with PMA. That isomer also reduced VEGF expression in un stimulated mouse 3T3-L1 adipocytes. Since VEGF can be regulated by cyclooxygenase-2 (COX-2), we determined whether CLA could alter COX-2 enzyme expression and $PGE_2$ production. The c9, t11-CLA isomer reduced not only COX-2 enzyme expression but also $PGE_2$ production. Thus, c9, t11-CLA could modulate neovascularization by alteration of VEGF expression from mammary tumor cells and adipocytes by reducing COX-2 metabolites.

Background: The DR-$70^{TM}$ immunoassay is a newly developed cancer diagnostic test which quantifies the serum fibrin degradation products (FDP), produced during fibrinolysis, by antibody reaction. The purpose of this study was to evaluate the potential of DR-$70^{TM}$ Immunoassay in screening malignant tumor. Methods: Sample subjects were 4,169 adults, both male and female, who visited the health promotion center of a general hospital from March 2004 to April 2005 and underwent the DR-$70^{TM}$ immunoassay test and other tests for cancer diagnosis. The patient group was defined as 42 adults out of the sample subjects who were newly diagnosed with cancer during the same time period when the DR-$70^{TM}$ immunoassay test was performed. Final confirmation of a malignant tumor was made by pathological analysis. Results: The mean DR-$70^{TM}$ level was $0.83{\pm}0.65{\mu}g/ml$ (range: 0.00 (0.0001)${\sim}7.42{\mu}g/ml)$ in the control group (n=4,127) as opposed to $2.70{\pm}2.33{\mu}g/ml$ (range: $0.12{\sim}9.30{\mu}g/ml)$ in the cancer group (n=42), and statistical significance was established (p<0.0001, Student t-test). When categorized by the type of malignant tumor, all cancer patients with the exception of the subgroups of colon and rectal cancer showed significantly higher mean DR-$70^{TM}$ levels compared with the control group (p<0.0001, Kruscal-Wallis test). The receiver operating characteristic (ROC) curve analysis revealed ${\geq}1.091{\mu}g/ml$ as the best cut-off value. Using this cut-off value, the DR-$70^{TM}$ immunoassay produced a sensitivity of 71.4%, a specificity of 70.1%, a positive predictability of 69.4%, and a negative predictability of 69.2% (1). Conclusion: A significant increase in the mean DR-$70^{TM}$ value was observed in the cancer group (thyroidal, gastric, breast, hepatic and ovarian) com pared with the control group. In particular, the specificity and sensitivity of the DR-$70^{TM}$ immunoassay was relatively high in the subgroups of breast, gastric, and thyroidal cancer patients. There is need for further studies on a large number of malignant tumor patients to see how the DR-$70^{TM}$ level might be changed according to the differentiation grade and postoperative prognosis of the malignant tumor.

The development of skin metastasis is usually a morbid prognostic feature although they occur infrequently. Adenocarcinomas account for up to about 70% of all metastatic skin cancer. In general, adenocarcinomas are the most difficult metastatic tumor to accurately identify the primary site because they don't have distinctive histological features. For this reason, immunohistochemistry have been used to help identify the origin of metastatic adenocarcinomas. This study performed immunohistochemical staining with metastatic adenocarcinomas of the skin using a variety of antisera to find out characteristic immunohistochemical findings of them. This study was made upon the 29 cases of metastatic adenocarcinomas of the skin, which had been confirmed histopathologically in Chonbuk National University Hospital from January, 1986 to April, 2006, Paraffin blocks were colledted and homemade tissue arrays were made. We performed immunohistochemical staning using 12 antibodies (MUC1, 2, 5AC, 6, cytokeratin (CK) 7, 20, thyroid transcription factor-1 (TTF-1), estrogen receptor (ER), progesterone receptor (PR), beta-catenin, cox-2, claudin-1). The mean age at the time of diagnosis was 60.7 years and the male to female ratio was 1.2:1.0. The most common primary site was lung, followed by stomach and colorectum. MUC1 was expressed by most colorectal, breast and lung adenocarcinoma. MUC2 was expressed infrequently. MUCSAC was expressed by most gastric and colorectal cancer MUC6 was not specific of any primary site in this series. CK7+/CK20+immunophenotype was observed in gastric, lung, colorectal adenocarcinoma. CK7+/CK20- immunophenotype was observed in breast, lung, endometrial, uterine cervical, bile duct adenocarcinoma, while CK7-/CK20+ immunophenotype was observed only in colorectal adenocarcinoma. This results show the utility of TTF-1 to confirm the pulmonary origin. On the other hand ER and PR were not useful markers to assess the origin of primary tumor in this series.

Background: The neutrophil-to-lymphocyte ratio (NLR) is a strong predictor of mortality in patients with colorectal, lung, gastric cancer, pancreatic and metastatic renal cell carcinoma. We here evaluated whether preoperative NLR is an independent prognostic factor for non-metastatic renal cell carcinoma (RCC). Materials and Methods: Data from 327 patients who underwent curative or palliative nephrectomy were evaluated retrospectively. In preoperative blood routine examination, neutrophils and lymphocytes were obtained. The predictive value of NLR for non-metastatic RCC was analyzed. Results: The NLR of 327 patients was $2.72{\pm}2.25$. NLR <1.7 and NLR ${\geq}1.7$ were classified as low and high NLR groups, respectively. Chi-square test showed that the preoperative NLR was significantly correlated with the tumor size (P=0.025), but not with the histological subtype (P=0.095)and the pT stage (P=0.283). Overall survival (OS) and disease-free survival (DFS) were assessed using the Kaplan-Meier method. Effects of NLR on OS (P=0.007) and DFS (P=0.011) were significant. To evaluate the independent prognostic significance of NLR, multivariate COX regression models were applied and identified increased NLR as an independent prognostic factor for OS (P=0.015), and DFS (P=0.019). Conclusions: Regarding patient survival, an increased NLR represented an independent risk factor, which might reflect a higher risk for severe cardiovascular and other comorbidities. An elevated blood NLR may be a biomarker of poor OS and DFS in patients with non-metastatic RCC.

목적: 역동적 자기공명영상에서 위암의 조영증강양상을 분석하여, 병변의 평가에 조영증강검사의 필요성을 규명하고자 하였다. 대상 및 방법: 병리조직학적으로 증명된 12명의 환자를 대상으로 하였다. 1.0T 자기공명영상장치를 이용하였고, FLASH T1 강조영상기법으로 조영제 주입전, 30초 후, 60초 후, 90초 후에 각각 횡단스캔을 얻었다. 검사 전 환자에게 1리터의 물을 마시게 하였고 장진경제인 Buscopan을 근육주사 하였다. 각 시기에서 병변의 신호 대 잡음비를 측정하였고, 병변과 췌장, 병변과 위장내 물과의 신호차이 대 잡음비를 측정하였다. 또한 각 시기의 영상에서 병변의 두으러짐을 0-3등급으로 나누어 두 명의 방사선과 의사가 합의하에 평가하였다. 결과: 병변의 신호 대 잡음비는 조영증강 전, 조영증강 후 30초, 60초, 90초의 시간경과에 따라 점차 증가하였다(38.7,42.5,57.4,65.7). 병변과 췌장과의 신호차이 대 잡음비는 10.5, 9.33, 9.99, 10.66으로 유의하게 증가하였다. 병변과 위장내 물과의 신호차이 대 잡음비도 1.24, 25.01, 39.30, 45.89로 유의하게 증가하였다. 그러나 정성적 분석에서는 조영 전 영상이 조영 후 영상에 비하여 병변의 두드러짐이 컸다(평균등급:2.8, 1.8, 1.6, 1.5). 병변의 신호강도는 조영증강 후 90초 지연영상에서 가장 높은 신호강도를 보여 병변의 위강쪽은 뚜렷하게 보였다. 그러나 병변과 위 주위 지방조직의 신호강도 차이가 줄어들어 전체적으로는 조영증강 전 영상에서 조영증강 후 영상보다 병변이 분명하게 보였다. 결론: 위암의 역동적 자기공명영상의 조영 전 영상에서 조영 후 영상보다 병변이 분명하게 보이므로 조영증강은 필요 없다고 생각된다.
