Anticoagulant-induced spontaneous small bowel hematoma is a rare cause of acute mechanical bowel obstruction. We report the case of a 77-year-old patient with complete arrhythmia due to atrial fibrillation under acenocoumarol 4mg daily who was seen for right iliac fossa pain. The laboratory tests showed a prothrombin rate (PT) of 12%, an International Normalized Ratio (INR) of 6, and an aPTT (activated partial thromboplastin time) of 43 seconds. Abdominopelvic ultrasound showed an echogenic pelvic effusion. The diagnosis of the small hematoma was made by abdominopelvic CT scan, which showed a thickening of the small bowel wall reducing its caliber associated with a parietal hematoma . The evolution was unremarkable under supplementation therapy vitamin K.

Evaluation of double-balloon enteroscopy in the management of type 1 small bowel vascular lesions (angioectasia): a retrospective cohort study.
BMC Gastroenterol
January 2025
Independent Researcher, İzmir, Turkey.
Background: Small-bowel angioectasia is commonly diagnosed and managed using double-balloon enteroscopy; however, rebleeding rates can vary significantly. This study aimed to identify and evaluate the clinical predictors of rebleeding in patients with small-bowel angioectasia.
Methods: This retrospective study focused on adult patients who underwent endoscopic management for small bowel vascular lesions (SBVLs).

Department of Pediatrics, University of Ulsan College of Medicine, Asan Medical Center Children's Hospital, 88, Olympic-ro 43-Gil, Songpa-Gu, Seoul, 05505, Republic of Korea.
Aims: Small bowel capsule endoscopy, which has been widely used to evaluate small bowel disease, has a risk of capsule retention (CR). The present systematic review and meta-analysis evaluated the accuracy of patency capsule (PC) and cross-sectional imaging (CSI) for predicting CR.
Methods: Databases, including MEDLINE/PubMed, EMBASE, Web of Science and the Cochrane library, were searched for articles through August 15, 2023, that investigated the diagnostic accuracy of PC or CSI for predicting CR.

Parkinson's Disease (PD) is a multisystem disorder in which dysregulated neuroimmune crosstalk and inflammatory relay via the gut-blood-brain axis have been implicated in PD pathogenesis. Although alterations in circulating inflammatory cytokines and reactive oxygen species (ROS) have been associated with PD, no biomarkers have been identified that predict clinical progression or disease outcome. Gastrointestinal (GI) dysfunction, which involves perturbation of the underlying immune system, is an early and often-overlooked symptom that affects up to 80 % of individuals living with PD.
