Abstract:
Gastrointestinal ischemia is caused by ischemic colitis in 50-60% of cases and is associated with high morbidity and mortality among patients. Ischemic proctosigmoiditis is a very rare disorder with only few cases reported. Due to collateral blood supply the rectum is only affected in 2-5% of all cases of ischemic colitis. We report a rare case of ischemic proctosigmoiditis caused by a retroperitoneal hematoma due to a pelvic fracture.

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...
