Recommendation 2 . Endoscopic biopsy should not be performed in the presence of a normal Z line or a Z line with < 1 cm of variability (strong recommendation, low level of evidence).
BE has been traditionally defined as the presence of at least 1 cm of metaplastic columnar epithelium that replaces the stratifi ed squamous epithelium normally lining the distal esophagus. The reason why such segments < 1 cm have been classifi ed as "specialized IM of the esophagogastric junction" (SIM-EGJ) and not BE is because of high interobserver variability as well as the low risk for EAC. Patients with SIM-EGJ have not demonstrated an increase in the development of dysplasia or EAC in large cohort studies aft er long-term follow-up, in contrast with patients with segments of IM >1 cm.

Acknowledging recent data on the low risk of malignant progression in patients with nondysplastic BE, endoscopic surveillance intervals are attenuated in this population; patients with nondysplastic BE should undergo endoscopic surveillance no more frequently than every 3-5 years.
Neither routine use of biomarker panels nor advanced endoscopic imaging techniques (beyond high-definition endoscopy) is recommended at this time. Endoscopic ablative therapy is recommended for patients with BE and high-grade dysplasia, as well as T1a esophageal adenocarcinoma. Based on recent level 1 evidence, endoscopic ablative therapy is also recommended for patients with BE and low-grade dysplasia, although endoscopic surveillance continues to be an acceptable alternative. Given the relatively common recurrence of BE after ablation, we suggest postablation endoscopic surveillance intervals.
ChomopreventionÀ¸·Î PPI »ç¿ëÀ» ±ÇÇÏ°í ÀÖ½À´Ï´Ù.
Recommendation 26 . Patients with BE should receive once-daily PPI therapy. Routine use of twice-daily dosing is not recommended, unless necessitated because of poor control of refl ux symptoms or esophagitis (strong recommendation, moderate level of evidence).
PPI therapy is common in patients with BE, in part because of the high proportion of those patients who also have symptomatic GERD. In these cases, the use of PPIs is substantiated by the need for symptom control, making consideration of chemoprevention secondary. However, even in patients without refl ux symptoms, in whom BE is incidentally found during evaluation of other symptoms and/or signs, the use of PPIs deserves consideration. Several cohort studies now suggest that subjects with BE maintained on PPI therapy have a decreased risk of progression to neoplastic BE compared with those with either no acid suppressive therapy or those maintained on H2RA therapy. In addition, the risk profi le of these medications is favorable in most patients, and the cost of this class of drugs has diminished substantially in recent years because of the availability of generic forms of the medications.
These factors, combined with the theoretical consideration that the same infl ammation that may be in part be responsible for pathogenesis of BE may also promote progression of BE, make the use of PPIs in this patient population appear justifi ed, even in those without GERD symptoms. Given the low probability of a randomized study of PPI use in BE, decisions regarding this intervention will likely rely on these retrospective data and expert opinion.

Methods: Among 492 patients with CD receiving upper gastrointestinal (GI) endoscopic evaluation in 19 Korean hospitals, we evaluated the endoscopic findings and gastric histopathologic features of 47 patients for our study. Histopathologic classification was performed using gastric biopsy tissues, and H. pylori infection was determined using the rapid urease test and histology. Results: There were 36 men (76.6%), and the median age of patients at the time of upper GI endoscopy was 23.8 years (range, 14.2-60.5). For CD phenotype, ileocolonic disease was observed in 38 patients (80.9%), and non-stricturing, nonpenetrating disease in 31 patients (66.0%). Twenty-eight patients (59.6%) complained of upper GI symptoms. Erosive gastritis was the most common gross gastric feature (66.0%). Histopathologically, H. pylori-negative chronic active gastritis (38.3%) was the most frequent finding. H. pylori testing was positive in 11 patients (23.4%), and gastric noncaseating granulomata were detected in 4 patients (8.5%). Gastric noncaseating granuloma showed a statistically significant association with perianal abscess/fistula (P=0.0496).
