Cure8 research brief
This study shows the appendix is often inflamed early in conventional UC and then remodels to fibrous obliteration over decades, implying the appendix may matter more in early disease. Differences between conventional UC and PSC-UC suggest distinct disease mechanisms that could affect surgical or research strategies.
Clinicians treating UC; colorectal surgeons; researchers studying UC pathophysiology or appendectomy; adult UC patients interested in surgical options.
This study examined appendiceal tissue from patients with conventional ulcerative colitis (UC) and PSC-associated UC who underwent total colectomy.
In conventional UC, most appendices showed either active inflammation or fibrous obliteration (FO), with a clear time-dependent pattern: active inflammation was common within 5 years of disease onset, while complete fibrous obliteration was more frequent after 20 years.
In some cases with periappendiceal endoscopic red patches, histology showed continuity from distal fibrous obliteration to proximal active inflammation within the same appendix. By contrast, appendices from PSC-UC patients were largely histologically intact despite severe colonic disease.
These findings suggest appendiceal inflammation is common early in conventional UC and tends to remodel over time to fibrous obliteration. The absence of appendiceal inflammation in PSC-UC supports a different appendiceal involvement and possibly different disease biology between PSC-UC and conventional UC.
Retrospective study of colectomy specimens (patients selected for surgery). Findings are pathology-based and suggest associations rather than treatment effects. Structured content is grounded in the published abstract.

Shows real-world long-term outcomes in a large Chinese UC cohort and highlights that baseline disease activity predicts need for escalation and colectomy risk; points to opportunities to improve treat-to-target care.
The appendix in conventional UC appears to be inflamed early and then remodels to fibrous obliteration over decades, which could influence thinking about timing or rationale for appendectomy-based interventions.
The report suggests adding acupuncture to anti-TNF therapy may improve short-term symptom control and mucosal healing and reduce early colectomy risk for a TCM-defined subgroup of ulcerative colitis patients, which could...
