A 3-year-old intact mixed hunting dog was referred to Gyeongsang Animal Medical Center with the clinical signs of vomiting, dyspnea, anorexia. The dogs had traumatic history that wounded at abdominal wall during the wild boar hunting 2 week ago. The dogs was diagnosed as extrahepatic biliary tract obstruction (EHBO) secondary to traumatic hernia. Diagnosis was based on radiographic features of a diaphragmatic hernia on survey radiography, dilated bile duct in abdominal ultrasonography and complete recovery due to the return of displaced organs into the peritoneal cavity and repair of the diaphragmatic rent. Diagnostic imaging and surgical intervention may result in a favorable outcome in dog with post hepatic obstruction secondary to diaphragmatic hernia. This case emphasizes the strangulation of bile duct by diaphragmatic rupture could be the cause of EHBO.

An abdominal aortic aneurysm occurs most commonly in older individuals (between 65 and 75), and more in men and smokers. The most important complication of an abdominal aortic aneurysm is rupture, which is most often a fatal event. An abdominal aortic aneurysm weakens the walls of the blood vessel, leaving it vulnerable to bursting open, or rupturing, and spilling large amounts of blood into the abdominal cavity. surface modeling is very useful to surgery for quantitative analysis of abdominal aortic aneurysm. the 3D representation and surface modeling an abdominal aortic aneurysm structure taken from Multi Detector Computed Tomography. The construction of the 3D model is generally carried out by staking the contours obtained from 2D segmentation of each CT slice, so the quality of the 3D model strongly defends on the precision of segmentation process. In this work we present deformable model algorithm. deformable model is an energy-minimizing spline guided by external constraint force. External force which we call Gradient Vector Flow, is computed as a diffusion of a gradient vectors of gray level or binary edge map derived from the image. Finally, we have used snakes successfully for abdominal aortic aneurysm segmentation the performance of snake was visually and quantitatively validated by experts.

The lymphatic system provides a route for the spread of inflammation and malignancies. The identification of nodal stations and lymphatic pathways of tumor spread is important for tumor staging, choice of therapy, and the prediction of the prognosis of patients with malignant diseases. Because lymph node metastasis is common in primary intra-abdominal malignant tumors, its detection is essential for radiologists to understand the pattern of disease spread. Using schematic pictures and color-coded CT images, this pictorial essay describes the locations and nomenclature of the abdominal lymph nodes. Furthermore, the lymphatic drainage pathways of the upper and lower gastrointestinal tracts, liver, gallbladder, bile duct, and pancreas have been highlighted. In addition, lymph nodes belonging to the regional lymph nodes in malignant tumors arising from each organ are described, and certain cases are presented with images from patients.

We present a rare case demonstrating successful endovascular management of an arterioureteral fistula involving the abdominal aorta. Arterioureteral fistulas are rare but life-threatening, with mortality rates ranging from 7% to 23%. Early recognition and prompt management are essential for preventing catastrophic consequences, including hypovolemic shock. However, recognition of an arterioureteral fistula requires a high index of clinical suspicion due to its rarity and the lack of a sensitive diagnostic method. Arterioureteral fistulas could be induced by traumatic events in patients who have a history of pelvic surgery, radiation, and prolonged placement of a ureteral stent. Endovascular stent graft placement could be a valid treatment option for arterioureteral fistulas involving the abdominal aorta.

Undifferentiated pleomorphic sarcoma (UPS) is a high-grade soft tissue sarcoma that arises from mesenchymal tissue. Primary UPS of the small intestine is extremely rare, and only a few cases have been reported in the literature. Its presentation is usually nonspecific; however, it may occasionally present as intussusception with intermittent abdominal pain. It is a highly aggressive tumor with a propensity for early distant metastasis to the peritoneum, lymph nodes, other abdominal organs, lungs and brain. To our knowledge, there are no reported cases of endobronchial metastasis from small intestine UPS. We report a rare case of UPS of the small intestine with endobronchial metastasis presenting as intussusception.

Inflammatory pseudotumors (IPTs) are uncommon, mass-forming lesions, predominantly involving the lung and orbit. Although the incidence of IPTs is rare in the abdomen and pelvis, they can be encountered as enhancing, soft-tissue lesions, mimicking malignancy or fibrosclerosing disease. Generally, they exhibit a wide range of nonspecific imaging features in various organs. Preoperative imaging diagnosis of IPTs in appropriate clinical settings may help determine proper patient management. In this article, we review radiologic findings of IPTs in the abdominopelvic cavity, including the liver, spleen, kidney, gastrointestinal tract, mesentery, pelvis, and retroperitoneum.

The objectives or this study were to examine reed value or waste onion in duck. Experimental chicks (Cherry Valley F$_1$, 1day old, 350 chicks) were randomly assigned in 8 treatment groups, each 45 chicks, and man-aged for 7 weeks (3 kg BW, 49 days old). Treatments were control, 3%, 6% of chopped onion-fed, 5%, 10% of onion extract fed, 6% of onion meal, 3%, 6% of fermented onion-fed. Feed intake was significantly (P<0.05) high in control group, but ADG was high in 3% chopped onion-fed group. Feed requirement was very efficient in all treatment groups except 6% fermented onion-fed group. Dressing rate was high in 5% onion extract-fed group, but it was not significant. Abdominal fat was the highest in control and 6% fermented onion-fed group and lowest in 6% chopped onion-fed group. Cholesterol content was lower in all treatment groups than in control group, but it was not significantly different. Stearic acid ($C_{18:0}$) content was significantly low in all treatment group (P<0.05). However, arachidonic acid ($C_{20:4}$) content was higher in treatment group than in control group. In result, onion diet was not significantly effect on palatability, feed intake, ADG in ducks. Duck meat of onion-fed contained low cho-lesterol and high unsaturated fat content.

This study was performed to determine the minimum dose of Poloxamer/Sodium alginate (PX/SA) mixture on preventing intraperitoneal adhesions to evaluate organ toxicity. Twenty five healthy adult mongrel dogs (weighing 4.68${\pm}$1.67 kg) were divided into five experimental groups composed of five dogs respectively; negative control group (NC, non-treated), positive control group (PC, 2% carboxymethyl chitosan solution treated), and experiment 1 group (E1, 0.25 ml PX/SA mixture of abraded area), experiment 2 group (E2, 0.5 ml PX/SA mixture of abraded area), experiment 3 group (E3, 1.0 ml PX/SA mixture of abraded area). Venous blood specimens were collected from all experimental animals for hematologic and biochemical analysis: WBC, fibrinogen, AST, ALT, ALP, BUN and creatinine. The anti-adhesion effect was evaluated using a serosa abrasion model. The denuded ileum was coated with PX/SA mixture, carboxymethyl chitosan solution or neither. The tensile strength of the adhesion site was evaluated with a tensiometer. For histopathological examination, tissue samples of the liver and kidney were collected from all dogs. According to the results, the frequency and tensile strength values for adhesion separation in PX/SA group were significantly lower than those in negative control group (p < 0.05). In E2 group, the tensile strength was significantly decreased in consideration of PX/SA dose. The values of AST, ALT, ALP, BUN and creatinine of the control and the experimental groups showed no statistical differences. No obvious microscopic differences were noted among tissue sections obtained from all groups. The results suggest that PX/SA mixture may be effective on reducing peritoneal adhesion formation in dog and that 0.5 ml PX/SA mixture of abraded area is most effective dose. Moreover, PX/SA mixture was considered not to have toxicity for the liver and the kidney.

Purpose : To improve the therapeutic results of postoperative recurrent disease and inoperable disease of stomach cancer, we used the thermoradiotherapy. We conducted a retrospective analysis of the results and compared the results of hyperthermia before radiotherapy and those of hyperthermia after radiotherapy Materials and Methods : From July 1994 to November 1996, we treated twenty patients with locally advanced stomach cancer and recurrent stomach cancer with thermoradiotherapy. We divided those patients into two groups : hyperthermia before radiotherapy group (PreRT group : 13 Patients) and hyperthermia after radiotherapy group (PostRT group : 7 patients). We performed radiation therapy with the total tumor dose of 3000-5040cGy in a traction of 180-300cGy and 5 fractions per week. Hyperthermia was performed with 8 MHz radiofrequency apparatus. PreRT group patients were treated daily for 30 minutes before the radiation therapy within the interval of ten minutes. And PostRT group patients were treated with 1-2 sessions Per week for 40-60 minutes after the radiation therapy within the interval of 10 minutes. Results : Overall response rate was $33.3\%$. This response rate appeared the same in both groups. Mean survival and 1 rear survival rate were 10.3 months and $16.5\%$. In PreRT group, mean survival and 1 year survival rate were 6.8 months and $9.0\%$, and in PostRT group, mean survival and 1 year survival rate were 7.7 months and $34\%$. There were no statistically significant difference between the prognostic factors and therapeutic results. Conclusion : The thermoradiotherapy was a safe treatment method in advanced and recurrent gastric cancer when compared with other treatment. Because the number of patients we treated was small and the follow up period was short. we were not able to draw any conclusions about the therapeutic efficacy of the sequence of radiation therapy and hyperthermia. Therefore, further clinical trials of thermoradiotherauy for stomach cancer appear to be warranted.
