Abstract:
Patients with diffuse large B-cell lymphoma (DLBCL) presenting with intestinal involvement are prone to develop perforation. Identification of those who are at high risk for this complication would enable a rational-based decision regarding preemptive surgery. Although computed tomography (CT) is widely used at diagnosis, data regarding its ability to predict intestinal perforation are scanty. We performed a retrospective single-center study, including all consecutive DLBCL patients presented with intestinal involvement, assessing predictors for perforation with an emphasis on CT-related parameters. Forty-nine patients were included, 43 (88%) underwent CT scan at diagnosis. Ten patients (20%) developed intestinal perforation. A univariate regression analysis found increased risk among patients with a concentric, transmural lesion, and a longer involved intestinal segment. In conclusion, CT scan results can define patients with DLBCL and intestinal involvement who are at risk for perforation, suggesting that a preemptive surgical resection should be considered in these cases.

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...

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.
