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.

Intestinal tuberculosis presents with nonspecific and variable clinical manifestations. It is rarely seen in current clinical practice and the diagnosis may be missed or confused with many other disorders such as Crohns disease and intestinal neoplasms. The route of infection by tuberculous enteritis is variable and the treatment regimens used for treating pulmonary tuberculosis are generally effective for tuberculous enteritis as well. Uncomplicated tuberculous enteritis can be managed with a nine to 12- month course of antituberculous chemotherapy. If not treated early, the prognosis for intestinal tuberculosis is poor, with an overall mortality of between 19 percent and 38 percent. However, 90 percent of patients will respond to medical therapy alone if started early. Therefore, early detection and treatment is essential. Here we report a case of intestinal tuberculosis secondary to miliary tuberculosis.

Intestinal tuberculosis (TB) is presented with nonspecific and variable clinical manifestations such as abdominal pain, diarrhea, fever and weight loss. Diagnosis of tuberculous enteritis may be missed or confused with many other chronic gastrointestinal disorders such as the Crohn disease and intestinal neoplasms. The diagnosis should be based on careful clinical evaluations, such as extra-intestinal signs and colonoscopic and histologic findings. Newer techniques such as PCR tests from the specimens through colonoscopic biopsy may be helpful to confirm diagnosis of tuberculous enteritis. The treatment regimens for pulmonary tuberculosis are generally effective for tuberculous enteritis as well. If not treated early, the prognosis of intestinal tuberculosis is poor. We report a case of tuberculous enteritis diagnosed by colonoscopic biopsy and TB PCR which was presented with diarrhea, abdominal pain, intermittent fever and weight loss in a 12-year-old girl with active pulmonary tuberculosis. The patient was treated successfully with antituberculosis agents for 11 months without any complications.

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.

Prompt and proper discovery of cause is important in lung cancer patients with signs and symptoms of intestinal obstruction because approach for treatment may differ according to its etiology and emergency operation can often be required to prevent more severe complications. In this report, we present two different causes of intestinal obstruction in lung cancer. Physicians need to be aware of these possibilities to differentiate the cause of intestinal obstruction in patients with lung cancer.

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.
