Background:
This study aimed to investigate the clinical characteristics and risk factors of primary gastrointestinal lymphoma (PGIL) in patients with gastrointestinal complications (GICs).
Methods:
A retrospective analysis was conducted on the clinical data of 148 patients with PGIL admitted to Yichang Central People's Hospital from January 2019 to August 2025. Univariable and multivariable logistic regression models were utilized to identify independent risk factors for GICs.
Results:
Patients with PGIL exhibited a high incidence (58.1%) of GICs, primarily bleeding, obstruction, and perforation. Bleeding predominantly involves gastric ulcerative lesions, whereas obstruction and perforation frequently affect the small intestine, with obstruction typically presenting endoscopically as protruding lesions. Compared to the non-GIC cohort, patients with GICs showed a significantly higher proportion of diffuse large B-cell lymphoma (DLBCL), poorer performance status (ECOG ≥ 2), and advanced tumor invasiveness. Furthermore, the GICs group demonstrated marked metabolic depletion, elevated systemic inflammation, significant bowel wall thickening, and lymphadenopathy. Crucially, multivariable analysis identified four independent risk factors for developing GICs: history of hypertension (odds ratio [OR] =3.724, CI: 1.149-12.074), primary intestinal site (OR=3.551, 95% CI: 1.240-10.170), deep lesion infiltration into the muscularis or serosa (OR=3.615, 95% CI: 1.132-11.546), and anemia (OR=4.288, 1.457-12.615).
Conclusion:
The high incidence of GICs in patients with PGIL is multifactorial. Early risk stratification and tailored interventions are crucial for patients presenting with hypertension, anemia, intestinal involvement, or deep tumor infiltration at the initial diagnosis to optimize therapeutic outcomes.

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.
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...
