Abstract
Purpose: Ulcerative colitis (UC) is a chronic, nonspecific inflammatory bowel disease primarily affecting the colorectal mucosa. The disease is characterized by a relapsing-remitting course and is currently incurable. Its pathogenesis is multifactorial, involving genetic predisposition, environmental triggers, immune dysregulation, and alterations in gut microbiota. The appendix plays a role in modulating intestinal immunity and maintaining microbial homeostasis. Left-sided colitis with appendiceal orifice inflammation (AOI) or periappendiceal erythematous patch (PARP) is a common endoscopic finding in UC. However, whether AOI in UC patients requires intervention remains debated.
Methods: Here, we report a rare case of a UC with AOI.
Results: By means of cholangioscope-assisted endoscopic retrograde appendicitis therapy (ERAT), copious purulent secretions were discovered and flushed out of the appendiceal cavity, resulting in clinical remission and endoscopic mucosal healing of UC.
Conclusion: Our case indicates that there may be some correlation between the appendix and the pathogenesis of ulcerative colitis. For refractory left-sided UC patients with AOI, ERAT-based management of appendiceal lumen inflammation may benefit patients.
期刊介绍：
The International Journal of Colorectal Disease, Clinical and Molecular Gastroenterology and Surgery aims to publish novel and state-of-the-art papers which deal with the physiology and pathophysiology of diseases involving the entire gastrointestinal tract. In addition to original research articles, the following categories will be included: reviews (usually commissioned but may also be submitted), case reports, letters to the editor, and protocols on clinical studies.
The journal offers its readers an interdisciplinary forum for clinical science and molecular research related to gastrointestinal disease.
