Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) are widely prescribed drugs, and they are known to be responsible for many cases of gastroduodenal ulcerations by inhibiting prostaglandin synthesis via blocking the cyclo-oxygenase production. Colonic side effects of these drugs are rare, but they are increasingly being reported to be due to the popularization of colonoscopy and the new formulations of drugs such as enteric coated pills or slow release pills. There is currently no consensus for making the clinical diagnosis and administering the proper therapy for drug-induced colonopathy in Korea. We experienced the patient who had multiple colonic ulcers after ingesting large amounts of aspirin and NSAIDs. In near future, we hope to determine the clinical and endoscopic features of drug associated colon injury.

Inflammatory myofibroblastic tumors (IMTs) are solid neoplastic mesenchymal proliferations composed of myofibroblastic spindle cells admixed with inflammatory infiltrates. The documented sites in the gastrointestinal tract include the esophagus, small intestine, colon, appendix, rectum, pancreas, spleen, liver, and Meckel's diverticulum. Biliary IMTs are rare, and IMTs arising from the ampulla of Vater have not been reported previously. Herein we report the case of a 65-year-old woman with an extrahepatic biliary obstruction due to IMT of the ampulla of Vater, and a successful therapeutic approach using endoscopic ultrasonography and endoscopic papillectomy.

Hyperplastic polyps are usually found in the stomach and they account for 50 to 90% of all gastric epithelial polyps. In contrast to the adenomatous polyps, it has been reported that most hyperplastic polyps are benign. However, in rare cases hyperplastic polyps have revealed carcinoma, and the incidence of malignant changes is generally recognized to be about 1 to 3%. Most of the reported cases of a hyperplastic gastric polyp with a transformation to adenocarcinoma were well differentiated histopathologically. Herein we report on an extremely rare case that involved the association of a hyperplastic polyp and focal signet ring cell carcinoma in the remnant stomach after subtotoal gastrectomy.

BACKGROUND/AIMS: Recent data from Western populations have suggested that patients with sporadic duodenal adenomas are at a higher risk for the development of colorectal neoplasia. In this study, we compared the frequency of colorectal neoplasia in patients with sporadic duodenal adenomas to healthy control subjects. METHODS: This retrospective case-control study used the databases of 3 teaching hospitals in Gyeonggi-do Province, South Korea. The colonoscopy findings of patients with sporadic duodenal adenomas were compared with those of age- and gender-matched healthy individuals who had undergone gastroduodenoscopies and colonoscopies during general screening examinations. RESULTS: Between 2001 and 2008, 45 patients were diagnosed endoscopically with sporadic duodenal adenomas; 26 (58%) of these patients received colonoscopies. Colorectal neoplasia (42% vs 21%; odds ratio [OR], 2.8; 95% confidence interval [CI], 1.1 to 7.4) and advanced colorectal adenoma (19% vs 3%; OR, 9.0; 95% CI, 1.6 to 50.0) were significantly more common in patients with sporadic duodenal adenomas than in healthy control subjects. CONCLUSIONS: Compared with healthy individuals, patients with sporadic duodenal adenomas were at a significantly higher risk for developing colorectal neoplasia. Such at-risk patients should undergo routine screening colonoscopies.

Superior mesenteric artery (SMA) syndrome is caused by compression of the transverse part of the duodenum between the SMA and the aorta, where the distance between these vessels decreases with loss of mesenteric fat. It occurs most frequently in patients with rapid weight loss. Conventionally, the diagnosis is established by digital fluoroscopy and contrast-enhanced spiral computed tomography (CT). A 17-year old woman was admitted via the emergency department with postprandial fullness, nausea, and bile stained vomiting. The initial radiological examination revealed severe gastroptosis. Fluoroscopic evaluation after barium swallowing failed due to a markedly distended stomach. The diagnosis of SMA syndrome was made by endoscopic ultrasound (EUS) using a mini-probe. EUS findings were in good agreement with the CT angiogram. A conservative trial was attempted, but symptoms remained refractory. Surgery was an alternative option and we treated the patient successfully with laparoscopic duodeno-jejunostomy.

Jejunal diverticulosis is a rare malady and it is often asymptomatic. It may lead to chronic non-specific or acute symptoms such as malabsorption, intussusception, obstruction, bleeding, perforation and abscess formation. It usually is seen as an incidental finding on computerized tomography, enteroclysis or during an emergency operation. Since the advent of double balloon enteroscopy and capsule endoscopy, several cases of small bowel diverticulosis with complications have recently been reported. Lipomas are the rare benign tumors of the small intestine with no malignant potential and they are mostly incidentally encountered during investigation of the gastrointestinal tract. We report here on a case of massive small bowel bleeding with jejunal diverticulosis, and a pedunculated elongated lipoma was incidentally found.

Trichuris trichiura (whipworm) is a ubiquitous parasite that resides in the human intestinal tract, and it is known as whipworm because of its whip-like appearance. Trichuriasis is rare in developed countries, but it is more prevalent in tropical countries and areas with suboptimal sanitation. In most patient, whipworm infection is asymtomatic but patient with heavy infection present with anemia, diarrhea, trichuris dysentery syndrome, abdominal pain, weight loss, appendicitis and rectal prolapse. It is characterized by the invasion of the colonic mucosa by the adult Trichuris and produces minor inflammatory changes at the sites of localization. Its diagnosis is usually made by identification of football-shaped eggs in the stool or by confirming adult whipworm during colonoscopy. We report four cases of whipworm infection that were incidentally diagnosed on colonoscopy.

Isolated spontaneous dissection of the superior mesenteric artery (SMA) without aortic dissection is a rare cause of acute mesenteric ischemia. A sudden decrease of intestinal blood flow can lead to fatal complications such as ischemic necrosis, shock, and death. Therefore, early diagnosis and therapeutic approach before the occurrence of intestinal infarction are the most important factor to determine the patient's prognosis. A 52-year-old male presented with postprandial periumbilical pain, and isolated spontaneous dissection of the superior mesenteric artery with mural thrombus was detected by abdominal computed tomography with contrast enhancement. By the percutaneous implantation of vascular metallic stent via femoral artery, he was treated successfully. We report a case of isolated spontaneous dissection of the SMA treated by a percutaneous endovascular stent replacement with a review of literature.

Inflammatory bowel diseases (IBD) is heterogeneous, chronic relapsing disorder. Inappropriate and exaggerated immune response for the luminal antigen is known as a main pathogenesis. Genetic, infectious, and environmental factors are responsible for unbalanced immune response, but the definite pathogenesis is still unclear. Genetic factor is the most important role of all. That is based on high concordance rate of identical twins and family history. The incident rate and prevalence of IBD for the Asian population is relatively lower than Western population, and the lack of NOD2 or TLR4 genetic polymorphisms in Korea and Japanese population suggests the difference in genetic background between Asian and Western population. In Korea, the case of familial aggregation of IBD is pretty rare. We report a case of the daughter with ulcerative colitis and her mother with Crohn's disease who have a -159C/T promoter polymorphism of CD14 gene for IBD.
