Mo1616 Enteroscopically Visible Differences Between Bleeding and Uncomplicated Small Bowel Tumors

212 (37%) had rDBE. There was no difference in age, gender or indications between the two groups. Mean age of patients who underwent aDBE was 68.5 years (21-94); and rDBE was 61.2 years (21-92). Gender distribution for aDBE: 181 (50%) male, 180 (50%) female. For rDBE, the gender distribution was 104 (49%) male, 108 (51%) female. Indications for aDBE were obscure overt GI bleed (OGIB) 158 (44%), occult GI bleed 131 (36%), abdominal pain 35 (10%), diarrhea 19 (5%), nausea & vomiting 10 (3%), suspected inflammatory bowel disease (IBD) 13 (4%) and surveillance of familial polyposis syndrome (FPS) 5 (1 %). Indications for rDBE were OGIB 67 (32%), occult GIB 59 (28%), abdominal pain 48 (22%), diarrhea 20 (9%), suspected IBD 18 (8%) and FPS surveillance 3 (1%). There was a significantly higher diagnostic yield with aDBE for vascular lesions(table 1). There was no difference between aDBE and rDBE for SB inflammation or tumors. There was also a significantly higher therapeutic yield with aDBE (table 2).There was a higher complication rate of bleeding with antegrade DBE (nZ10, 3%) compared with retrograde DBE (nZ1, 0.4%). There was one perforation (n Z 1, 0.4%) with retrograde DBE. Conclusion: Antegrade DBE has a significantly higher diagnostic and therapeutic yield than retrograde DBE for all SB lesions, mainly angioectasias. Our results support antegrade DBE as the initial approach for majority of patients with suspected SB disorders. Retrograde DBE may be useful when antegrade DBE is negative, and in management of patients with known distal SB lesions. Table 1. Diagnostic Yield with Antegrade and Retrograde DBE
