For many patients with inflammatory bowel disease (IBD) proctocolitis, proctectomy offers symptom and disease control, albeit at the expense of a potentially morbid proctectomy. There are select situations, however, where definitively leaving an IBD rectum in situ, either in or out of intestinal continuity, may be a suitable alternative to proctectomy. This review explores the rare occasions where leaving the rectum in situ may be advisable and discusses the subsequent implications.

The intestinal barrier serves as a boundary between the mucosal immune system in the lamina propria and the external environment of the intestinal lumen, which contains a diverse array of microorganisms and ingested environmental factors, including pathogens, food antigens, toxins, and other foreign substances. This barrier has a central role in regulating the controlled interaction between luminal factors and the intestinal immune system. Disruptions of intestinal epithelial cells, which serve as a physical barrier, or the antimicrobial peptides and mucins they produce, which act as a chemical barrier, can lead to a leaky gut.

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease for which current therapeutic approaches still face many dilemmas, and targeting macrophage polarization and metabolism for the treatment of this disease is a potentially effective strategy. The gut microbial metabolite indole-3-propionic acid (IPA) has favorable anti-inflammatory and antioxidant effects and plays a role in a variety of disease models. IPA is effective in the treatment of UC, but the underlying mechanisms have not been well explored.

Inflammatory bowel disease (IBD) remains a pressing global health challenge, necessitating novel therapeutic strategies. Succinate, a metabolite known for its role in type 2 immunity and tuft cell activation in the small intestine, presents its potential in IBD management. However, its impact on colonic inflammation has not been explored.

Background: Sishen Wan (SSW) is a traditional herbal formula widely used in China to treat inflammatory bowel disease (IBD). However, effective compound(s) and the mechanism(s) of action remain mostly unelucidated.
Purpose: A demonstration study was carried out to identify the main components of SSW, investigate its effects, and explore the target mechanism in the treatment of IBD.

Mitochondrial dysfunction is increasingly recognized as a shared feature of Alzheimer's disease (AD) and inflammatory bowel disease (IBD), linked through overlapping pathways of hypoxia and immune dysregulation. Our study integrated transcriptomic and genetic analyses to uncover mitochondria-related mechanisms underlying these diseases. By analyzing multiple AD and IBD datasets through differential expression gene (DEG) analyses, biological pathway enrichment, and co-expression module construction, we identified hypoxia-induced mitochondrial dysfunction as a central risk factor for both conditions.
