Background And Aims: Computer-aided detection software (CADe) has shown promising results in real-time polyp detection, but a limited head-to-head comparison of the available CADe systems has been performed. Moreover, such systems have not been compared to endoscopists using standardized videos. This study aims to compare the performance of three CADe systems in detecting polyps, employing a novel standardized methodology.

- Polyps in the colon are recognized as indicators of potential cancer, and while many are non-cancerous, their characteristics correlate with colon cancer risk.
- Several automated methods for detecting and segmenting polyps exist, but they often lack rigorous testing on diverse datasets, which limits their reliability across different populations.
- To address this gap, a new dataset called PolypGen has been created from six medical centers, featuring over 300 patients and 3,762 meticulously annotated polyp labels, enhancing the accuracy and applicability of polyp detection techniques.
Background: Chronic mesenteric ischemia (CMI) due to either atherosclerosis of the mesenteric arteries or median arcuate ligament syndrome (MALS) is an underdiagnosed entity. The etiology of MALS and its existence have been debated and questioned. We aimed to identify plasma biomarkers indicating mesenteric ischemia in patients with CMI and MALS.

We assumed that the patients suspected of CMI of the atherosclerotic origin or median arcuate ligament syndrome (MALS) could be identified earlier with endoscopic duplex ultrasound (E-DUS).
Patients And Methods: Fifty CMI patients with CTA-verified stenosis of either ≥50% and ≥70% of celiac artery (CA) and superior mesenteric artery (SMA) were examined with E-DUS and transabdominal duplex ultrasound (TA-DUS).
A 68-year-old woman with iron deficiency anemia (due to gastrointestinal bleeding) was evaluated. Over a period of two years she received iron supplementation perorally and intravenously, as well as multiple blood transfusions, but the hemoglobin level did not exceed 10 g/dL. The investigations included upper endoscopy, duodenoscopy with side optical view, ileocolonoscopy, capsule endoscopy, antegrad single-balloon enteroscopy and conventional angiography of the abdominal vessels.
