Purpose:
We aimed to evaluate the CT findings of stercoral colitis (SC).
Methods:
Forty-one patients diagnosed with SC between February 2006 and April 2015 were retrospectively reviewed.
Results:
Rectosigmoid colon was the most frequently involved segment (100%, n=41). CT findings can be summarized as follows: dilatation >6 cm and wall thickening >3 mm of the affected colon segment (100%, n=41), pericolonic fat stranding (100%, n=41), mucosal discontinuity (14.6 %, n=6), presence of free air (14.6%, n=6), free fluid (9.7%, n=4), and pericolonic abscess (2.4%, n=1). The sign most related with mortality was the length of the affected colon segment >40 cm.
Conclusion:
CT has an important role in SC, since life-threatening complications can be easily revealed by this imaging modality. Increased length of involved colon segment (>40 cm) is more likely to be associated with mortality.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

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...
