Abstract

fetched live from OpenAlex

Capsule endoscopy (CE) has been widely utilized for the diagnostic assessment of patients with known/suspected small bowel disease.The newly developed CapsoCam Plus capsule utilizes four cameras at sequential 90 intervals in its mid-section thus permitting a 360-degree panoramic perspective of the SB mucosa with a 15+ battery life. A panoramic view has been suggested to improve overall visualization of the SB therefore potentially improving diagnostic yield. This capsule, unlike other small bowel capsules must be retrieved upon excretion utilizing a magnetic kit. To assess the use of CapsoVision CapsoCam SV-3 in patients referred for suspected small bowel disease at St. Paul’s Hospital. A retrospective chart review from 01/16 – 09/18 assessing consecutive capsule procedures utilizing the CapsoVision CapsoCam SV-3 was performed. Data was gathered from physician-generated reports from an office database. Information acquired included basic demographics, indication, extent of examination, gastric transit time, small bowel transit time, yield, adverse events, capsule retention, recovery rates and recommendations for follow up. Acquired data included 46 patients receiving a study CapsoCam Plus; indications: 40% OGIB, 52% IDA, 4% abdominal pain, and 2% Crohn’s disease. 89% of studies were performed to cecal visualization. Mean time for first gastric image, first duodenal image, and first cecal image was 0:06:16, 0:54:26, and 4:38:54 respectively. Average gastric transit time and small bowel transit time were 0:48:35 and 3:45:15. 94% were retrieved using retrieval kits provided to patients. 2% retrieved endoscopically from the stomach, 2% retained in TI and 2% not retrieved due to failure of patient to use retrieval kit. 72% of patients were found to contain normal SB, 17% contained SB ulceration/erosive disease and 11% did not demonstrate the entire small bowel. Recommendations for follow up included supportive therapy (48%), more aggressive Fe supplementation (2%), repeat capsules (17%) and 15% for routine office follow up and discussion. CapsoCam Plus had a high retrieval rate of 94% demonstrating that with appropriate patient selection recovery rates are very high. Only 2 (4%) of patients had retained capsules, which is compatible with previous reports using other capsules. Most patients in this study had a normal small bowel, partially secondary to patient selection; however, images and completion rates were adequate to assess small bowel in the vast majority of patients. This capsule has comparable imaging capabilities to other small bowel capsules and the potential advantage of easily doing the study remotely. None

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
