목적: 분문부 위선암의 치료는 아직까지는 근치적 수술이 원칙이고 특히 식도 침윤을 갖는 type II 분문부 위선암은 충분한 절제연을 확보하기 위한 노력이 필요하다. 식도 침윤정도에 따라서 개흉과 개복을 통해 식도-위 절제를 하고 식도 대체술을 하는데, 그 중 저자들은 대장간치의 적응과 치료성적 등을 함께 알아 보고자 하였다. 대상 및 방법: 1994년 1월부터 2006년 12월까지 연세대학교 의과대학 외과학 교실에서 저자에게 위암으로 수술을 받은 1,087명의 환자 중 type II 분문부 위선암으로 좌 또는 우 흉복부 개복과 경복부 절개(경열공)를 이용해 근치적 식도-위절제술을 하고 식도 대체술로 좌측 대장을 간치한 환자 10예를 대상으로 같은 type으로 Roux-en-Y를 받은 환자들과 후향적으로 비교 분석 하였다. 결과: 남녀가 각각 9명, 1명 이었고 중간 연령은 52.5세(16~72세), 수술시간은 $449.00{\pm}87.39$ (SD)분이었고 평균 재원일수는 $20.60{\pm}6.73$ (SD)일이었다. 식도-위 동시성암은 1예가 있었고, 종양으로부터 근위부 절제연까지의 거리는 $6.56{\pm}3.65cm$였으며 종양의 크기는 $9.90{\pm}3.97cm$였는데 Roux-en-Y군의 값들과 차이를 보였다(sex and age matched analysis, P=0.019, P=0.046). 수술 사망은 없었고, 술 후 합병증은 2예가 있었는데 각각 문합부 협착과 폐기흉이었다. 사망은 총 4예가 있었고 수술 후 환자 대부분(83%)은 체중이 늘어 체중증가가 최대 16 kg까지 있었다. 결론: 식도 침윤을 하는 type II 분문부 위암에서 크기가 매우 큰 경우는 근치적 식도-위 절제술이 필요하다. 식도 대체 장기로는 좌측 대장을 이용 할 수 있는데 수술 시간이 길지만, 근치적 수술에 유리하고 식도-공장 문합술에 비해 수술 합병증이 많지는 않아, 재건술로 좌측 대장을 이용하는 방법도 가치가 있다고 생각한다.

This study describes recent trends in incidence, survival and prevalence of subgroups of esophageal and gastric cancer in Linzhou city between 2003 and 2009. Data of esophageal and gastric cancer for the period of interest were extracted from the Linzhou Cancer Registry. Using information on tumor morphology or anatomical site, data were divided into six groups; esophageal squamous cell carcinoma, esophageal adenocarcinoma, other and unspecified types of esophageal cancer, and cardia, non-cardia, and unspecified anatomical site of stomach cancer. Incidence, survival and prevalence rates for each of the six cancer groups were calculated. The majority of esophageal cancers were squamous cell carcinomas (82%). Cardiac cancer was the major gastric cancer group (64%). The incidence of esophageal squamous cell carcinoma and gastric cardiac cancer increased between 2003 and 2009. Both esophageal and gastric cancer had a higher incidence in males compared with females. Overall survival was poor in all sub-groups with 1 year survival ranging from 45.9 to 65.6% and 5 year survival ranging from 14.7 to 30.5%. Prevalence of esophageal squamous cell carcinoma and gastric cardiac cancer was high (accounting for 80% overall). An increased focus on prevention and early diagnosis, especially in esophageal squamous cell carcinoma and gastric cardiac cancer, is required.

Purpose: We conducted this study to study the clinical correlation between the characteristics of gastric cancer and serum selenium and zinc levels. Materials and Methods: The following data were measured in the baseline serum selenium and zinc levels of 74 patients with curative gastrectomy subsequent to confirmed gastric cancer, from March 2005 to August 2012. Results: Among the 74 gastric cancer patients, 53 patients were male. Mean serum selenium and zinc levels were $118.7{\pm}33.1$ ug/L and $72.2{\pm}24.3$ ug/dl, respectively. Seven patients (9.5%) showed lower selenium level, and 33 patients (44.6%) showed lower zinc level. Serum Selenium level was $99.1{\pm}31.8$ ug/L in cardia cancer group (10 cases) and $121.8{\pm}32.4$ ug/L in non-cardia cancer group (64 cases)(P=0.044). According to tumor gross type, zinc level was $78.7{\pm}29.6$ ug/dl in early gastric cancer (33) and $66.9{\pm}17.8$ ug/dl in advanced gastric cancer (41) (P=0.064). Conclusions: The serum selenium level was highly correlated with the location of gastric cancer. The serum zinc level was lower in advanced gastric cancer.

Objectives: In the context of the global decrease in mortality due to gastric cancer, previous studies have reported that the effect of chronic Helicobacter pylori (H. pylori) infection on the incidence of gastric cancer varies among regions. This systematic review was conducted to investigate H. pylori as a risk factor for gastric cancer in Korea, where the incidence of gastric cancer is among the highest in the world. Methods: A search strategy was established to identify articles published in Korean as well as in English. Ultimately, we included observational studies conducted among Korean patients that designed with an age-matched and sex-matched control group that reported the odds ratio associated with H. pylori. Gastric cancer cases were subdivided into overall (OGC), cardia (CGC), non-cardia (NGC), early (EGC), advanced, intestinal (IGC), and diffuse forms of gastric cancer. Summary odds ratios (SORs) with 95% confidence intervals (CIs) were calculated in the meta-analysis using a random-effect model. Results: Eleven case-control studies were ultimately selected. H. pylori was associated with an SOR of 1.81 (95% CI, 1.29 to 2.54) for OGC. Additionally, statistically significant risks were observed for CGC, NGC, EGC, and IGC. Conclusions: Chronic H. pylori infection was found to raise the risk of gastric cancer among Koreans, with the highest risk observed for CGC and EGC (SOR=2.88 for both). Follow-up clinical epidemiologic studies are needed to assess the effects of current treatments aimed at eradicating H. pylori infections.

Purpose: To determine the clinical value of the Siewert classification for gastic-cancer patients in Korea, we evaluated and compared the clinicopathologic factors of type II and type III cancer. Materials and Methods: The medical records of 89 consecutive patients who had undergone surgery for an adenocarcinoma of the gastroesophageal junction (GEJ) at the Department of Surgery, Hanyang University Hospital, between Jun. 1992 and Dec. 2003 were reviewed retrospectively. Results: There were one patient with type I, 12 pateints with type II and 77 patients with type III. During the same period, 1,341 patients underwent surgery for a gastric carcinoma, so proportion of GEJ cancer being $6.6\%$. The median followup duration was 31 months (range: $2\∼135$ months), and the follow-up rate was $100\%$. Between type II and type III cancers, there were no significant differences in the clinicopathologic variables including age, sex, gross appearance, histologic type, depth of invasion, and pathologic stage. The longest diameter of the tumor was larger in type III ($6.1\pm2.1$ cm) than in type II ($3.9\pm1.1$ cm)(P=0.001). A total gastrectomy with Roux-en-Y esophagojejunostomy was done most frequently, while jejunal interposition was done in 3 cases of type II and 2 cases of type III. More than a D2 lymphadenectomy was done all cases. The numbers of dissected lymph nodes and metastatic lymph nodes in type II were 43.8 and 5.8 respectively, while they were 49.8 and 8.1 in type III, but the difference between the two groups were not statistically significant. The mean length of the proximal resection margin was $15\pm5$ mm in type II and $21\pm13$ mm in type III, but this difference was not statistically significanct. The time to recurrence after operation was 19.3 months in type II and 16.9 months in type III. The five-year survival rates of type II and III were $68.8\%\;and\;52.7\%$ respectively, but difference was not significant. Conclusion: There were no significant differences in the clinicopathologic variables, including survival rate, between type II and type III cancers in Korean patients According to these findings, it appears to be reasonable to classify type III cancer as a cardia cancer in a broad sense.

Gastric cancer is the second most common cause of cancer-related deaths in the world. Although certain dietary factors and lifestyles have been suggested to be associated with gastric carcinogenesis, there have been few investigations focusing on rural areas. A case-control study was therefore carried out to investigate the risk factors of gastric cardia cancer (GCC) in rural areas of Linzhou. A total of 470 newly diagnosed cases of GCC and 470 healthy controls were included. Face-to-face interviews were conducted, using a uniform questionnaire containing questions on demographics, per capita income, living habits, dietary habits and family history of tumors. The relationship between putative risk factors and GCC was assessed by odds ratios (OR) and their 95% confidence intervals (95%CI) derived from conditional logistic regression model by the COXREG command using SPSS 12.00. Multivariate logistic regression analysis was used to evaluate simultaneously the effects of multiple factors and other potential confounding factors. Multivariate logistic analysis showed that smoking (OR=1.939, 95%CI:1.097-3.426), alcohol drinking (OR=2.360, 95%CI: 1.292-4.311), hot food consumption (OR=2.034, 95%CI: 1.507-2.745), fast eating (OR=1.616, 95%CI: 1.171-2.230), mouldy food (OR=4.564, 95%CI: 2.682-7.767), leftover food (OR=1.881. 95%CI: 1.324-2.671), and family history of tumor (OR=2.831, 95%CI: 1.588-5.050) were risk factors for GCC. High per capita income (OR=0.709, 95%CI: 0.533-0.942), high education level (OR=0.354, 95%CI: 0.163-0.765), consumption of fresh fruits (OR=0.186, 95%CI: 0.111-0.311) and vegetables (OR=0.243, 95%CI: 0.142-0.415), and high BMI (OR=0.367, 95%CI: 0.242-0.557) were protective factors for GCC. Our data indicate that unhealthy lifestyle and dietary habits might be important contributors to GCC in this population.

본 증례에서는 우연히 한 환자에서 위장관 간질 종양과 점막하 종양 형태의 MALT 림프종을 동시에 발견하였고, 이를 내시경적 절제술로 치료한 사례이다. 현재 환자는 절제술 후 2년 동안 질병의 진행 없이 외래에서 경과 관찰 중이다. 아직 MALT 림프종과 위장관 간질종양에서 내시경적 점막하 절제술은 정립된 치료 방법이 아니지만, 본 증례처럼 성공적으로 치료될 수 있음을 경험하였기에 문헌고찰과 함께 보고하는 바이다. 아직은 내시경적 절제술로 치료한 사례가 적지만, 향후 내시경적 절제술 후 긴 기간 동안 추적 관찰된 증례들이 모인다면 조기위암처럼 표준화된 치료법으로 시행될 수 있기를 기대한다.

목적: 현재 위분문부 및 식도암에 대한 근분 치로 원칙은 수술적 치료이며, 이에 대한 방법으로는 기존에는 주로 개흉을 요하는 McKeown술식(transthoracic esophagectomy, TTE)을 시행하였으나 최근에는 개흉술을 시행하지 않고 경열공을 통한 식도절제술(transshiatal esophagectomy, THE)도 많이 시행하고 있다. 이에 최근 본원에서 시행한 TTE와 THE의 임상 및 병리 결과를 분석하여 봄으로써 기존의 TTE에 대한 THE의 유용성에 대해 고찰해 보고자 한다. 상 및 방법: 최근 10년간 부산대학교병원에서 식도 및 위분문부암으로 진단 받고 수술적 치료를 받은 52예를 대상으로 후향적으로 자료를 수집, 분석하였다. 결과: 총 52예 중 20예에서 TTE를 32예에서 THE를 시행하였다. TTE는 중간부식도암 12예, 하부식도암 8예에서 시행되었고, THE는 중간부식도암 7예, 하부식도암 15예, 위분문부암 10예에서 시행되었다. TTE 후 식도대체장기로는 17예에서 위를, 3예에서 대장을 사용했으며, THE에서는 29예에서 위를, 3예에서 대장을 사용하였다. 술 후 합병증은 TTE를 시행한 13예(폐렴, 흉수 등 호흡기게 합병증 5예, 문합부유출 3예, 간병증 2예, 창상감염 1예, 패혈증 1예)에서, THE를 시행한 19예(문합부협착 13예, 흉수 3예, 문합부유출 1예, 창상감염 1예, 회귀후두신경마비 1예)에서 발생했다. 술 후 치료기간 동안 사망한 예는 TTE에서 1예 있었다. 수술 후 입원기간은 TTE에서 평균 25.6일, THE에서 20.6일 이었다. 결론: THE가 수술 이환율(morbidity)과 사망률(mortality)이 낮고 술식이 간편하여 시행하기가 용이하여 기존의 개흉을 통한 TTE 술식과 비교했을 때 식도절제를 요하는 대부분의 암환자들에게 유용한 술식이라 하겠다.

The forty patients with carcirLoma of the esophagus or cardia seen at National Medical Center between November 1983 and April 1994 underwent surgical exploration. The esophagogastrectomy was carried out in 29 of 40 patients, one case through right thoracotomy, the others through left thoracotomy. Two patients underwent colon bypass surgeries due to upper esophageal cancer Transhiatal esop agectomy was performed In one case. Feeding gastrostomy or feeding jejunostomy were performed in 8 patients due to the advanced stage or malnutrition. In this report, we evaluated the long-term results in the 28 patients who underwent esophagogastrectomy for palliation through the left thoracotomy. There were 25 men(89%) and 3 women(11 %), and the mean age was 58.65$\pm$7.15 years(range, 46 to 73 years). The most frequent preoperative symptoms included dysphagia (22), weight loss (15), chest pain (6), vomiting (1), and hoarsness (1). Twenty-three patients had sqamous cell cancers of mid-and lower esophagus and five adenocarcionomas of cardia. One patient died in the hospital within 30 days of the op- eration for a hospital mortality rate of ).7%, Cause of death was sepsis due to anastomotic leakage. There were five additional complications in five patients; acute respiratory distress syndrome (1), post-op- erative bleeding (1), diaphragmatic hernia (1), acute renal failure (1) and late raft stenosis (1). The one year, 1틴o years, and three years acturial survival rate were 75.6$\pm$9.5%, 43.2$\pm$ 11.6%, 21.6: 10.5$\circledcirc$ re- spectively. The average survival was 21.8 months. The data from this study suggest that esophagogastrectomy through the left thoracotomy can achieve resonable long-term palliation for carci- noma of the esophagus. The operation can be performed with a low operative mortality and few serious postoperative complications.
