V$^2$-SfMLearner: Learning Monocular Depth and Ego-motion for Multimodal Wireless Capsule Endoscopy [PDF]

arXiv
Deep learning can predict depth maps and capsule ego-motion from capsule endoscopy videos, aiding in 3D scene reconstruction and lesion localization. However, the collisions of the capsule endoscopies within the gastrointestinal tract cause vibration perturbations in the training data.

Segmentation of Bleeding Regions in Wireless Capsule Endoscopy for Detection of Informative Frames [PDF]

arXiv, 2018
Wireless capsule endoscopy (WCE) is an effective mean for diagnosis of gastrointestinal disorders. Detection of informative scenes in WCE video could reduce the length of transmitted videos and help the diagnosis procedure. In this paper, we investigate the problem of simplification of neural networks for automatic bleeding region detection inside ...

Role of noncontrast enhanced abdominal ultrasound in the diagnostic assessment of pediatric inflammatory bowel disease

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Assessment of small bowel involvement when diagnosing inflammatory bowel disease (IBD) delineates clinical subtype and disease extension. The gold standard for small bowel assessment is magnetic resonance enterography (MRE), but MRE is not always feasible for children.

Prevalence of repeat faecal immunochemical testing in symptomatic patients attending primary care

Colorectal Disease, Volume 24, Issue 12, Page 1498-1504, December 2022., 2022
Abstract Aim The faecal immunochemical test (FIT) for faecal haemoglobin (f‐Hb) helps determine the risk of colorectal cancer (CRC) and has been integrated into symptomatic referral pathways. ‘Safety netting’ advice includes considering referral for persistent symptoms, but no published data exists on repeated FITs.

2D Reconstruction of Small Intestine's Interior Wall

, 2018
Examining and interpreting of a large number of wireless endoscopic images from the gastrointestinal tract is a tiresome task for physicians. A practical solution is to automatically construct a two dimensional representation of the gastrointestinal ...

Capsule endoscopy in celiac disease

World Journal of Gastroenterology, 2008
Video capsule endoscopy is an attractive and patient-friendly tool that provides high quality images of the small bowel. Obscure gastrointestinal bleeding is the primary and most evaluated indication to capsule endoscopy; however, indications are expanding and a small number of preliminary reports have been presented concerning the role of video ...

SPNing our wheels—Pancreatic solid pseudopapillary neoplasm as an extraluminal etiology of persistent duodenal ulceration

JPGN Reports, EarlyView.
Abstract Pediatric upper gastrointestinal (GI) bleeding secondary to duodenal ulceration is a potentially serious and life‐threatening condition with a broad differential diagnosis. We present a pediatric case of a pancreatic head solid pseudopapillary neoplasm (SPN) presenting with duodenal ulceration and recurrent upper GI bleeding.

Capsule endoscopy in neoplastic diseases

World Journal of Gastroenterology, 2008
Until recently, diagnosis and management of small-bowel tumors were delayed by the difficulty of access to the small bowel and the poor diagnostic capabilities of the available diagnostic techniques. An array of new methods has recently been developed, increasing the possibility of detecting these tumors at an earlier stage.

Learning to Adapt Foundation Model DINOv2 for Capsule Endoscopy Diagnosis [PDF]

arXiv
Foundation models have become prominent in computer vision, achieving notable success in various tasks. However, their effectiveness largely depends on pre-training with extensive datasets. Applying foundation models directly to small datasets of capsule endoscopy images from scratch is challenging.
