Investigating the molecular mechanisms underlying the co-occurrence of Parkinson's disease and inflammatory bowel disease through the integration of multiple datasets.

Parkinson's disease (PD) and inflammatory bowel disease (IBD) are chronic diseases affecting the central nervous system and gastrointestinal tract, respectively. Recent research suggests a bidirectional relationship between neurodegeneration in PD and intestinal inflammation in IBD. PD patients may experience gastrointestinal dysfunction over a decade before motor symptom onset, and IBD may increase the risk of developing PD.

Methods: A workshop involving six international experts from China and Japan with substantial experience with LCI developed the classification.

Balloon-assisted endoscopic submucosal dissection for treating small intestinal lipomas: Report of two cases.

Background: Most small intestinal lipomas are treated surgically, and some require repeated surgeries for multiple lipomas. However, application of endoscopic submucosal dissection (ESD) technology in the deep small intestine is rarely reported owing to the special anatomical structure of the small intestine, medical equipment limitations, and the lack of relevant experience among endoscopists.

Case Summary: Two patients with small intestinal lipomas treated at the Air Force Medical Center from November 2015 to September 2019 were selected to undergo balloon-assisted ESD to treat the lipomas and explore the technical feasibility and safety of ESD for treating small intestinal lipomas.

Primary experience of small bowel polypectomy with balloon-assisted enteroscopy in young pediatric Peutz-Jeghers syndrome patients.

For Peutz-Jeghers syndrome (PJS) patients, small bowel polyps develop and result in symptoms at an early age. Balloon-assisted enteroscopy (BAE) is verified as a safe and efficient choice to evaluate and remove small intestinal polyps in adult PJS. But the safety of BAE, especially BAE-facilitated polypectomy for young pediatrics, is little known.
