| Abstract | Determining factors that predict a favorable disease course without anti-tumor necrosis factor (TNF) agents would help establish a more cost-effective strategy for Crohn’s disease (CD). A retrospective chart review was performed for CD patients with disease durations > 10 years who had not received anti-TNF agents as first-line therapy. Patients were divided into 2 groups: those who received neither anti-TNF agents nor bowel resection (G1), and those who had received an anti-TNF agent and/or bowel resection (G2). The patient backgrounds, therapies and clinical courses were compared between the groups. A total of 62 CD patients met the inclusion criteria (males: 71%; median duration of follow-up: 19 years). Six patients were included in G1; they were significantly less likely to have upper gastrointestinal lesions than G2 (p=0.007). A multivariate analysis revealed that the significant factors for avoidance of bowel resection without anti-TNF treatment were non-stricturing and non-penetrating behaviors, and absence of upper gastrointestinal lesions at the diagnosis (hazard ratios 0.41 and 0.52; p=0.004 and 0.04, respectively). In consideration of the long treatment course of CD, patients with non-stricturing and non-penetrating behaviors and no upper gastrointestinal lesions should not be treated with anti-TNF agents as first-line therapy. |

| Abstract | To evaluate the usefulness of colonoscopy for the detection of ileal involvement in patients with intestinal follicular lymphoma, seventeen patients with intestinal follicular lymphoma who underwent colonoscopy and biopsy sampling from the terminal ileum were enrolled. The patients were divided into 2 groups: cases with ileal involvement (n=6) and cases without ileal involvement (n=11). Patients’ clinical backgrounds were compared between the two groups. Subsequently, 10 board-certified endoscopists independently evaluated the endoscopic pictures and determined whether the ileum was involved with follicular lymphoma. Infiltration of follicular lymphoma cells were identified in 6 patients (35.3%). Cases with positive ileal involvement were diagnosed with follicular lymphoma at a younger age than were cases without ileal involvement (55.4±7.4 vs. 68.1±10.3 years, p=0.011). Macroscopically, in patients with ileal involvement, there were multiple polypoid elevations smaller than 5 mm in 4 cases, single polypoid elevation smaller than 5 mm in 1 case, and single polypoid elevation larger than 5 mm in 1 case. In patients without ileal involvement, there were no lesions in the terminal ileum in 7 cases, and multiple polypoid elevations smaller than 5 mm were seen in 4 cases. The accuracy of the macroscopic evaluation by 10 board-certified endoscopists was 68.8%. Colonoscopy is particularly recommended during the initial workup of patients with follicular lymphoma diagnosed at age ≤ 60 years. The diagnosis of ileal involvement based on morphology alone is difficult; thus, biopsy and pathologic diagnosis are required for accurate diagnosis. |

| Abstract | We retrospectively analyzed the cases of 14 patients (9 women, 5 men, mean age: 51.6 years) with cytomegalovirus (CMV) involvement in the esophagus, stomach, and/or duodenum diagnosed at a single center, to determine their endoscopic features and clinical backgrounds. Thirteen patients (92.9%) had hematologic disease; the other had rheumatoid arthritis. Of the former, 12 patients underwent allogeneic hematopoietic stem cell transplantation, and 9 of these patients had graft-versus-host disease (GVHD) before undergoing esophagogastroduodenoscopy (EGD). All 14 patients had been taking one or more immunosuppressive agents including cyclosporine (n=10), corticosteroids (n=9), mycophenolic acid (n=6), tacrolimus (n=3), and methotrexate (n=1). Tests for CMV antigenemia were positive in 11 patients (78.6%). EGD examinations revealed esophageal (n=3), gastric (n=9), and duodenal involvement (n=6). Macroscopically, esophageal lesions by CMV infection presented as redness (n=1), erosions (n=1), and ulcers (n=1). Gastric lesions manifested as redness (n=7), erosions (n=3), exfoliated mucosa (n=2), and verrucous erosions (n=1). Mucosal appearances in the duodenum varied: redness (n=2), ulcers (n=2), multiple erosions (n=2), single erosion (n=1), edema (n=1). CMV was detected even in the intact duodenal mucosa (n=1). In conclusion, physicians must recall the relevance of CMV infection when any mucosal alterations exist in the upper gastrointestinal tract of immunosuppressed patients. |

| Abstract | The usefulness of endoscopy in marginal ulcer bleeding has rarely been studied, and the optimal method for preventing rebleeding is unclear. Here we assessed the efficacy of endoscopy in marginal ulcer bleeding and examined the efficacy of proton pump inhibitors (PPIs) in the prevention of rebleeding. A total of 28 patients with marginal ulcer bleeding (21 men, 7 women; median age 58.5 years) were treated by endoscopy. We analyzed the clinical characteristics, results of endoscopic therapy, characteristics of rebleeding patients, and relation between the use of PPIs and the duration of rebleeding. Sixteen patients had active bleeding. Initial hemostasis was achieved in all patients. There were no procedure-related adverse events. Rebleeding occurred in one patient within the first month and in 7 patients thereafter. There was a significant difference in the rebleeding rate between the patients who received a PPI and those who did not. In a multivariate analysis, the non-use of PPIs was a risk factor for rebleeding (hazard ratio, 6.22). Therapeutic endoscopy is effective in achieving hemostasis from marginal ulcer bleeding. PPIs may prevent rebleeding from marginal ulcers. |

| Abstract | Several studies have identified a relationship between myelodysplastic syndrome and Behçetʼs disease (BD), especially intestinal BD, and trisomy 8 appears to play an important role in these disorders. Despite this, only few case reports or series have been reported in gastroenterology, meaning that endoscopic findings and characteristics of intestinal BD have not been clarified yet. In this report, we describe three cases of intestinal BD associated with myelodysplastic syndrome and trisomy 8, and discuss the clinical features and problems of these disorders from a gastroenterology perspective. |

| Abstract | The sensitivity and specificity of magnified endoscopic features for differentiating follicular lymphoma from other diseases with duodenal whitish lesions have never been investigated. Here we compared the magnified endoscopic features of duodenal follicular lymphoma with those of other whitish lesions. We retrospectively reviewed the cases of patients with follicular lymphoma (n＝9), lymphangiectasia (n＝7), adenoma (n＝10), duodenitis (n＝4), erosion (n＝1), lymphangioma (n＝1), and hyperplastic polyp (n＝1). The magnified features of the nine follicular lymphomas included enlarged villi (n＝8), dilated microvessels (n＝5), and opaque white spots of various sizes (n＝9). The lymphangiectasias showed enlarged villi, dilated microvessels, and white spots, but the sizes of the white spots were relatively homogeneous and their margin was clear. Observation of the adenoma and duodenitis revealed only whitish villi. Although the lymphangioma was indistinguishable from the follicular lymphomas by magnified features, it was easily diagnosed based on the macroscopic morphology. In conclusion, magnified endoscopic features, in combination with macroscopic features, are useful for differentiating follicular lymphomas from other duodenal diseases presenting whitish lesions. |
