Background:
This study determined the long-term outcome after colectomy for acute severe ulcerative colitis (ASUC) and assessed whether the duration of in-hospital medical therapy is related to postoperative outcome.
Methods:
All patients who underwent urgent colectomy and ileostomy for ASUC between 1994 and 2000 were identified from a prospective database. Patient details, preoperative therapy and complications to last follow-up were recorded.
Results:
Eighty patients were identified, who were treated with intravenous steroids for a median of 6 (range 1-22) days before surgery. Twenty-three (29 per cent) also received intravenous ciclosporin. There were 23 complications in 22 patients in the initial postoperative period. Sixty-eight patients underwent further planned surgery, including restorative ileal pouch-anal anastomosis in 57. During a median follow-up of 5.4 (range 0.5-9.0) years, 48 patients (60 per cent) developed at least one complication. Patients with a major complication at any time during follow-up had a significantly longer duration of medical therapy before colectomy than patients with no major complications (median 8 versus 5 days; P = 0.036).
Conclusion:
Delayed surgery for patients with ASUC who do not respond to medical therapy is associated with an increased risk of postoperative complications.

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...

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
