Three case reports of glutaraldehyde-induced chemical colitis
1Department of Gastroenterology, The Second Affiliated Hospital of Zhejiang University School of Medicine No. 88 Jiefang Road, Hangzhou 310009, Zhejiang, China.
Abstract:
Currently, chemical colitis in clinical practice is mainly caused by iatrogenic factors. The disinfectant glutaraldehyde is one of the common drugs that can cause chemical colitis, but there are few reports about it. From August 2019 to August 2022, 1457 cases of colonoscopy were performed in the endoscopy room of the Second Affiliated Hospital of Zhejiang University School of Medicine and Songyang County People's Hospital, and 3 cases of chemical colitis caused by glutaraldehyde residue are discussed in this report. All 3 cases occurred on the same endoscopic system and same day. These 3 patients were hospitalized and treated with bowel rest, hydration, peroral Kangfuxin solution, dexamethasone combined with Kangfuxin solution local enema treatment, and empiric antibiotic. In conclusion, standardized management of cleaning and disinfection should be strengthened in departments carrying out enteroscopy, especially those using the concentrated glutaraldehyde immersion solution and cleaning after immersion, to prevent the occurrence of acute chemical enteritis related to disinfectant.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
