Bulge or mass? A diagnostic dilemma of capsule endoscopy

Development of a novel index to discriminate bulge from mass on small-bowel capsule endoscopy

“…The prevalence of smooth, round protrusions in the small bowel we found was 5.8%, a figure similar to that of our previous report, 14 and only 24% of these were SMMs. GI stromal tumors and neuroendocrine tumors were found at the end of the diagnostic and therapeutic work-up, and this is not surprising because these two types of tumors arise from the subepithelial layers of the bowel wall.…”

“…Based on 4 criteria identified in a previous retrospective and observational study on 246 consecutive SBCEs, 14 we developed a simple index, called SPICE (smooth, protruding lesions index on capsule endoscopy), aimed at discriminating SMMs from innocent bulges. In the present article, we report the results of a prospective study planned to validate this novel index.…”

Optimizing lesion detection in small-bowel capsule endoscopy: from present problems to future solutions

“…Subsequently, 192 CE images were reviewed: 50 vascular, 73 inflammatory and 69 protruding lesions. Visualization was more enhanced for vascular pathology than it was for inflammatory or protruding lesions (56 vs 23 vs <10%, respectively) [111,112].…”

“…Tsai's algorithm was also tested in a phantom simulator, prepared from readily available materials such as cardboard boxes [111,112]. To represent the different colors and shapes seen inside the small intestine, flat or protruding objects in red, yellow and white were used in the phantom models.…”
