Introduction:
Acute severe ulcerative colitis (ASUC) is a critical manifestation of ulcerative colitis (UC), often necessitating colectomy when medical management fails. Despite advancements in therapeutic interventions such as corticosteroids, biologics, and JAK inhibitors, a significant proportion of patients require surgery, with colectomy rates ranging from 10% to 15%.
Areas Covered:
This paper reviews the factors influencing the timing and necessity of colectomy in ASUC management, emphasizing the importance of multidisciplinary decision-making involving gastroenterologists and surgeons.
Expert Opinion:
Key surgical indications include failure of medical therapy, toxic megacolon, perforation, uncontrolled bleeding, and systemic deterioration. Delays in surgery can result in higher morbidity and mortality rates, making timely intervention essential. This review highlights surgical techniques, including total colectomy and end ileostomy, and discusses potential complications, urging a balanced approach to optimize patient outcomes.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
