As the incidence of early gastric cancer increases, laparoscopic surgery has become one of the treatments of choice for gastric cancer. With the increase of laparoscopic surgery, the chance of discovering aberrant anatomy during the operation also increases. We present a case of laparoscopic total gastrectomy in gastric cancer patients with intestinal malrotation. Intestinal malrotation occurs in one in every 500 births. We found that laparoscopic total gastrectomy in such patients can be performed successfully when it is performed with a proper Roux limb orientation through an alternative minilaparotomy.

Two Domestic Korean Shorthair cats presented with dyschezia and vomiting. Computed tomography revealed a colonic mass with calcification and lymph node metastasis in case 1, and a small intestinal mass with disseminated mesenteric metastasis and calcification in case 2. Histopathology revealed intestinal adenocarcinoma with osseous metaplasia. Case 1 died two months after surgery from distant metastasis; and case 2 showed no metastasis for five months but presented with anorexia, euthanized seven months after diagnosis. Metastatic intestinal adenocarcinoma with bone formation should be considered as differential diagnosis for calcification on imaging, and lymph node metastasis at diagnosis may indicate poor prognosis.

Background: Excess energy supply induces chronic low-grade inflammation in association with oxidative stress in various tissues including intestinal epithelium. The objective of this study was to investigate the effect of high-fat diet (HFD) on intestinal cell membrane integrity and intestinal tumorigenesis in $Apc^{Min/+}$ mice. Methods: Mice were fed with either normal diet (ND) or HFD for 12 weeks. The number of intestinal tumors were counted and biomarkers of endotoxemia, oxidative stress, and inflammation were determined. Changes in intestinal integrity was measured by fluorescein isothiocyanate (FITC)-dextran penetration and membrane gap junction protein expression. Results: HFD group had significantly higher number of tumors compared to ND group (P < 0.05). Blood total antioxidant capacity was lower in HFD group, while colonic 8-hydroxy-2'-deoxyguanosine level, a marker of oxidative damage, was higher in HFD group compared to that of ND group (P < 0.05). The penetration of FITC-dextran was substantially increased in HFD group (P < 0.05) while the expressions of membrane gap junction proteins including zonula occludens-1, claudin-1, and occludin were lower in HFD group (P < 0.05) compared to those in ND group. Serum concentration of lipopolysaccharide (LPS) receptor (CD14) and colonic toll-like receptor 4 (a LPS receptor) mRNA expression were significantly higher in HFD group than in ND group (P < 0.05), suggesting that significant endotoxemia may occur in HFD group due to the increased membrane permeability. Serum interleukin-6 concentration and myeloperoxidase activity were also higher in HFD group compared to those of ND group (P < 0.05). Conclusions: HFD increases oxidative stress disrupting intestinal gap junction proteins, thereby accelerating membrane permeability endotoxemia, inflammation, and intestinal tumorigenesis.

An eight-year-old Maltese dog presented with diarrhea and anorexia. Ultrasonography revealed marked focal wall thickening with loss of layering in the distal ileum. Contrast-enhanced computed tomography (CT) revealed a preserved wall layer with hypoattenuating middle wall thickening. In some segments of the lesion, small nodules protruding toward the mesentery from the outer layer were observed. Histopathology revealed focal lipogranulomatous lymphangitis (FLL) with lymphangiectasia. This is the first report to describe the CT features of FLL in a dog. CT features of preserved wall layers with hypoattenuating middle wall thickening and small nodules can assist in diagnosing FLL in dogs.

소아에 있어서 복부 및 위장관 결핵은 매우 드문 질환이며 임상증상도 복통, 설사, 체중감소, 발열 등 비특이적이어서 크론병, 맹장염 및 다른 위장관 질환의 증상과 크게 다르지 않아 복부 질환의 진단에 있어 간과하기 쉽다. 특히 결핵성 장염은 사망률이 19-38%에 이르지만 조기에 진단, 치료하면 예후가 좋아 조기 진단의 중요성이 높다. 저자들은 복부팽만, 발열을 주소로 내원한 환아에게 속립성 폐결핵에 합병된 결핵성 장염 1례를 경험하였기에 보고하는 바이며, 아직도 결핵 유병율이 높은 우리나라에서는 위장관 증세를 호소하는 환아에게 위장관 결핵의 가능성을 고려해야 하겠다.

결핵은 다양한 임상양상을 보이는 감염병으로 과거에 비해 많이 감소하였고 소아 결핵도 점차 줄어들고 있으나 여전히 중요한 감염병이다. 소아의 결핵은 성인과는 다른 임상적 특징을 가지며 폐외 결핵의 빈도가 성인보다 높고, 청소년의 결핵은 결핵균 감염에서 실제 질병으로 발전될 위험이 크다. 폐외 결핵 중 장결핵은 증상이 비특이적이고 다양하여 진단이 늦어질 경우 사망률 및 이환율이 높아질 수 있다. 크론병 또는 만성적인 소화기 질환과의 감별이 중요하며, 최근 대장 내시경의 발달로 감별 진단이 용이해지고 있다. 저자들은 6개월간 지속된 설사와 복통, 체중 감소와 간헐적이고 반복적인 $37.5-38^{\circ}C$의 발열로 내원한 12세 여아에게서 대장 내시경 검사를 하여 시행한 생검 조직의 PCR 검사와 조직학적 소견으로 장결핵을 진단하였고, 연이어 촬영한 흉부 방사선 상 활동성 폐결핵으로 진단되어 11개월간의 항결핵제 치료로 완치된 증례를 경험하였다.

Purpose: Owing to differences in the general characteristics of gastric cancer (GC) according to histological type, the association of GC risk factors, such as diet, may also differ depending on the histological type. We investigated the associations between individual and combined intake of soy products, vegetables, and dairy products and GC mortality by following up cases of death among Korean GC cases and whether these associations differ according to the histological type. Materials and Methods: A total of 508 GC cases were enrolled from two hospitals between 2002 and 2006. Their survival or death was prospectively followed up until December 31, 2016, through a review of medical records and telephonic surveys. Finally, 300 GC cases classified as intestinal- or diffuse-type GC cases were included. The median follow-up period was 7.1 years. Results: In the fully adjusted model, a high intake of soy products (hazard ratio [HR], 0.43; 95% confidence interval [CI], 0.19-0.96) and the combination of soy products and vegetables (HR, 0.34; 95% CI, 0.12-0.96) or soy products and dairy products (HR, 0.37; 95% CI, 0.14-0.98) decreased the mortality from intestinal-type GC. In particular, patients consuming various potentially protective foods (HR, 0.23; 95% CI, 0.06-0.83) showed a highly significant association with a lower mortality from intestinal-type GC. However, no significant association was found with diffuse-type GC. Conclusions: High intake of potentially protective foods, including soy products, vegetables, and dairy products, may help increase survival in intestinal-type GC.

Gastric cancer (GC) has high mortality owing to its aggressive nature. Tumor angiogenesis plays an essential role in the growth, invasion, and metastatic spread of GC. The aim of this work was to review the angiogenic biomarkers related to the behavior of GC, documented in the literature. A search of the PubMed database was conducted with the MeSH terms: "Stomach neoplasms/blood [MeSH] or stomach neoplasms/blood supply [MeSH] and angiogenic proteins/blood [Major]". A total of 30 articles were initially collected, and 4 were subsequently excluded. Among the 26 articles collected, 16 examined the role of vascular endothelial growth factor (VEGF), 4 studied endostatin, 3 investigated angiopoietin (Ang)-2, 2 studied the Ang-like protein 2 (ANGTPL2), and 1 each examined interleukin (IL)-12, IL-8, and hypoxia inducible factor. Regarding VEGF, 6 articles concluded that the protein was related to lymph node metastasis or distant metastases. Five articles concluded that VEGF levels were elevated in the presence of GC and decreased following tumor regression, suggesting that VEGF levels could be a predictor of recurrence. Four articles concluded that high VEGF levels were correlated with poor prognosis and lower survival rates. Ang-2 and ANGTPL2 were elevated in GC and associated with more aggressive disease. Endostatin was associated with intestinal GC. VEGF is the most extensively studied angiogenic factor. It is associated with the presence of neoplastic disease and lymph node metastasis. It appears to be a good biomarker for disease progression and remission, but not for diagnosis. The data regarding other biomarkers are inconclusive.

장 폐색의 증상 및 징후가 있는 폐암 환자에서는 원인에 대한 신속하고 적절한 규명이 중요한데 이는 장 폐색의 원인에 따라 치료 방침이 달라지고, 종종 더욱 심한 합병증을 예방하기 위해 응급수술이 필요한 경우도 있기 때문이다. 본 논문에서는 폐암과 동반하여 각기 다른 원인에 의한 장 폐색이 있었던 두 증례를 보고하고자 한다. 첫 번째는 폐암 치료 중 발생한 10 kg의 급격한 체중감소가 있었던 57세 남자로 반복되는 답즙성 구토를 주소로 내원하였다. 전이성 병변은 발견되지 않았으나 전산화단층촬영 및 상부위장관조영술에서 십이지장 제3부의 폐색이 보여 상장간막 동맥 증후군으로 진단되었다. 두 번째 증례는 68세 남자로 3년 전 폐암으로 수술 및 보조항암화학치료를 받았으나 재발하여 경과를 관찰 중이던 환자로 오심, 구토 및 복통으로 내원하였는데 검사 결과 소장 전이로 인한 장 폐색으로 진단되어 수술적 치료를 시행하였다. 폐암 환자에서 장 폐색이 의심될 때 그 원인이 될 수 있는 여러 가능성들을 항상 염두에 두고 진단 및 치료 방침을 세워야 할 것으로 생각된다.

Gastroduodenal intussusception is an infrequent cause of gastrointestinal obstructive disease. Benign neoplasms, gastrointestinal stromal tumors and pedunculated adenocarcinomas of less than 5 cm have been reported to cause gastroduodenal intussusception. We report a case of 76-year-old woman who was presented with a 3-day history of nausea and vomiting due to upper gastrointestinal obstruction. Computed tomography revealed gastroduodenal intussusception with the transpyloric herniation of alarge gastric hyperplastic polyp. The patient underwent laparoscopic wedge resection with the eversion method.
