Automated polyp detection in colon capsule endoscopy.
TL;DR: An algorithm is proposed that relieves the labor of a human operator analyzing the frames in the video sequence of Colon capsule endoscopy by acting as a binary classifier, which labels the frame as either containing polyps or not, based on the geometrical analysis and the texture content of the frame.

Sandra Lopes,Pedro Figueiredo,Francisco Portela,Paulo Freire,Nuno Almeida,Clotilde Lérias,Hermano Gouveia,Maximino Correia Leitão +7 more
TL;DR: The results suggest that capsule findings are not helpful in the work‐up of IBDU/IC patients with negative serology and that a change in therapy due to a diagnosis of CD was made for only 1 patient, who presented nonspecific findings.
Automatic polyp detection in pillcam colon 2 capsule images and videos: preliminary feasibility report.
TL;DR: Preliminary results suggest that the proposed geometry-based polyp detection scheme works well, not only by allowing the detection of polyps but also by differentiating them from nonprotruding images found in the films.
Urgent capsule endoscopy is useful in severe obscure-overt gastrointestinal bleeding.
Nuno Almeida,Pedro Figueiredo,Sandra Lopes,Paulo Freire,Clotilde Lérias,Hermano Gouveia,Maximino Correia Leitão +6 more
TL;DR: The diagnostic yield of CE is assessed in severe obscure‐overt gastrointestinal bleeding (OOGIB) by using capsule endoscopy to examine the entire small bowel.
