Fecal examination for survey of natural prevalence of Balantidium coli was performed on 1080 healthy bred pigs in Korea, and the positive rate was 56.2%. In order to observe if Balantidium coli might be a secondary invader after certain initiation of the intestinal lesions, the piglet groups preinfected with the protozoa experimentally were treated with Salmonella cholerasuis, Trichuris. cold stress, HCI, and immunosuppressive drug respectively, but no relation was found between them. Also the protozoa were not detected from the intestinal lesions spontaneously formed of 107 pigs which were checked in the slaughter house. According to the above results, Balantidium coli is not directly associated with the formation of any lesions in the pig's large intestine.

Background: Little is known about capsule endoscopy (CE) findings in patients with intestinal tuberculosis who exhibit small bowel lesions. The aim of the present study was to distinguish between Crohn's disease (CD) and intestinal tuberculosis based on CE findings. Methods: Findings from 55 patients, who underwent CE using PillCam SB CE (Given Imaging, Yoqneam, Israel) between February 2003 and June 2015, were retrospectively analyzed. Results: CE revealed small bowel lesions in 35 of the 55 patients: 19 with CD and 16 with intestinal tuberculosis. The median age at diagnosis for patients with CD was 26 years and 36 years for those with intestinal tuberculosis. On CE, three parameters, ≥10 ulcers, >3 involved segments and aphthous ulcers, were more common in patients with CD than in those intestinal tuberculosis. Cobblestoning was observed in five patients with CD and in none with intestinal tuberculosis. The authors hypothesized that a diagnosis of small bowel CD could be made when the number of parameters in CD patients was higher than that for intestinal tuberculosis. The authors calculated that the diagnosis of either CD or intestinal tuberculosis would have been made in 34 of the 35 patients (97%). Conclusion: The number of ulcers and involved segments, and the presence of aphthous ulcers, were significantly higher and more common, respectively, in patients with CD than in those with intestinal tuberculosis. Cobblestoning in the small bowel may highly favor a diagnosis of CD on CE.

Behçet's disease (BD) is a systemic immunological disorder characterized by recurrent mucosal ulcerative lesions including oral and genital ulcerations in association with skin and ocular involvements. BD also can involve the gastrointestinal tract. Gastrointestinal involvement of BD is one of the major causes of morbidity and mortality for this disease. However, clinical data are quite limited because of the rarity of intestinal BD. Therefore, the management of intestinal BD is heavily dependent on expert opinions and standardized medical treatments of intestinal BD are yet to be established. In this brief review, the authors summarized the currently available medical treatments such as 5-aminosalicylic acids, corticosteroids, immuno-modulators, and anti-TNF agents. Moreover, we sought to suggest a treatment algorithm for intestinal BD based on the recently published and updated data.

Intestinal lymphangiectasia is a rare disease which is causing protein-losing enteropathy. Treatment of intestinal lymphangiectasia can be a challenge for clinicians because of the lack of specific guidelines regarding pharmacological indications. We sought to introduce a diagnostic approach and suggest guidelines for treatment. After exclusion of secondary intestinal lymphangiectasia, magnetic resonance lymphangiography is a promising tool for the assessment of abnormal lymphatic lesions in primary intestinal lymphangiectasia. Determining the extent of the lesion provides direction for treatment options. Focal short-segment intestinal lymphangiectasia can be treated via intestinal resection or radiologic embolization after dietary therapy failure. Diffuse intestinal lymphangiectasia and extensive lymphangiectasia should be treated with several drugs with a full understanding of their mechanisms.

Objective: To evaluate the usefulness of MR imaging for diseases of the small intestine, emphasizing a comparison with CT. Materials and Methods: Thirty-four patients who underwent both CT and MR imaging using FLASH 2D and HASTE sequences were analyzed. All patients had various small bowel diseases with variable association of peritoneal lesions. We compared the detectabilities of CT and MR imaging using different MR pulse sequences. The capability for analyzing the characteristics of small intestinal disease was also compared. Results: MR imaging was nearly equal to CT for detecting intraluminal or peritoneal masses, lesions in the bowel and mesentery, and small bowel obstruction, but was definitely inferior for detecting omental lesions. The most successful MR imaging sequence was HASTE for demonstrating bowel wall thickening, coronal FLASH 2D for mesenteric lesions, and axial FLASH 2D for omental lesions. MR imaging yielded greater information than CT in six of 12 inflammatory bowel diseases, while it was equal to CT in six of seven neoplasms and inferior in five of seven mesenteric ischemia. In determining the primary causes of 15 intestinal obstructions, MR imaging was correct in 11 (73%) and CT in nine (60%) patients. Conclusion: MR imaging can serve as an alternative diagnostic tool for patients with suspected inflammatory bowel disease, small intestinal neoplasm or obstruction.

Tumors of the small intestine are rare and generally asymptomatic or with nonspecific symptoms. The small intestine is difficult to approach using conventional endoscopy, and early diagnosis of the small intestinal tumors is difficult. Therefore, many of the small intestinal tumors are diagnosed at an advanced stage, which makes the prognosis poor. Premalignant lesions of the small intestine or known risk factors of small bowel cancer are sporadic adenoma, adenoma associated with familial adenomatous polyposis, hamartomatous polyp associated with Peutz-Jeghers syndrome, Crohn's disease, and celiac disease. Therefore, it is necessary to recognize that the small bowel cancer can occur in these patients with premalignant lesions or risk factors of small bowel cancer. To reduce the possibility of small bowel cancer or to detect at an earlier stage, attention should be paid to screening and surveillance of these patients with premalignant lesions or risk factors of the small bowel cancer.

Of 72 patients with vitelline duct and vessel remnants, 45 (62.5 %) had symptomatic lesions. The mean age of the patients was 27.9 months. Males predominated (4.6 : 1). There were 22 cases of Meckel's diverticulum, 6 of Meckel's diverticulum attatched to the umbilicus with a fibrous band, 6 cases of patent vitelline duct, 5 cases of vitelline artery remnants as a fibrous band and 2 cases each of umbilical sinus and polyp, and vitelline cyst. Twenty-three patients (51 %) presented with intestinal obstruction, 6(13 %) with rectal bleeding, 4(9 %) with perforated Meckel's diverticulum, 5 with intestinal juice drainage through umbilicus, 5 with umbilical lesions, 1 with abdominal mass, and 1 with sepsis. Intestinal obstruction due to fibrous band developed during infancy(average age; 4.6 months). Seventeen asymptomatic Meckel's diverticulum, 8 obliterated vitelline artery remnants and 1 vitelline vein remnant as fibrous band, and 1 vitelline cyst were found incidentally at laparotomy. About 82 % of the complicated Meckel's diverticulum presented in infants and children less than 4 years of age.

Background: It is generally accepted that gastric carcinomas are preceded by a sequential multistage process that includes chronic gastritis, gastric atrophy, usually with intestinal metaplasia (IM), and dysplasia. This series of changes in gastric carcinogenesis is often initiated by Helicobacter pylori (H pylori) infection. The aim of the present study was determination of gastric histopathologic changes in IM patients after at least one year in Guilan province, Iran. Materials and Methods: This case-series study was conducted in Guilan Gastrointestinal and Liver Disease Research Center (GLDRC) during 2010 to 2011. Gastric biopsy was performed for all 71 known cases of IM and precanceric lesions including gastric atrophy, IM, dysplasia and H pylori infection were determined after at least one year. Results: Of the total of 71 patients with established IM who were enrolled, 50 had complete-type IM and 21 had incomplete-type IM. Fifty two people had H pylori infection. H pylori eradication was achieved in 39 patients (75%). Secondary pathology findings of patients with IM were complete metaplasia (39.4%), incomplete metaplasia (32.4%), dysplasia (23.9%) and other precanceric lesions (4.2%). Dysplasia (20%vs 33%) occurred in patients who had complete and incomplete IM at baseline respectively (p>0.05). Age, gender, family history of gastric cancer(GC); smoking habits and NSAIDs use were not associated with gastric premalignant lesions in initial and secondary pathologies (p>0.05). The difference became statistically significant between H pylori infection in patients with more than 3 years diagnostic intervals (p<0.05). Statistical difference between eradicators and non-eradicators was not significant. Conclusions: We found that incomplete IM increased the risk of subsequent dysplasia in this study.

Dieulafoy lesions, vascular anomalies typically found along the gastrointestinal tract, have been viewed as rare and obscure causes of sudden intestinal bleeding, especially in pediatric patients. Since their discovery in the late 19th century, the reported incidence has increased. This is due to an increased awareness of, and knowledge about, their presentation and to advanced endoscopic diagnosis and therapy. Our patient was a three-year-old male, without a complex medical history. He presented to the emergency department with acute hematemesis with blood clots and acute anemia requiring blood transfusion. Endoscopy revealed four isolated Dieulafoy lesions along the lesser curvature of the stomach, which were treated with an epinephrine injection. The Dieulafoy lesion, although thought to be rare, should be considered when investigating an acute gastrointestinal bleed. These lesions have been successfully treated endoscopically. Appropriate anticipation and preparation for diagnosis and therapy can lead to optimal outcomes for the pediatric patient.
