Patients on anticoagulation therapy, particularly those on warfarin, are at risk of gastrointestinal bleeding, gum bleeding, hematuria, and ecchymosis. However, it is rare for such patients to present with intramural or submucosal bleeding leading to intestinal obstructive symptoms. Sub-mucosal intestinal bleeding due to prolonged anticoagulant use is uncommon. Literature suggests that the duodenum and small intestine are common locations for anticoagulant-induced hematomas, occurring in approximately 1 case per 2,500 anticoagulated patients per year. However, intramural colonic hematomas are rarely reported. Spontaneous anticoagulant induced hematomas may develop as early as 10 days after starting therapy. We report the case of a 63-year-old female who presented with recto-sigmoid sub-mucosal bleeding causing obstructive symptoms. The patient was managed surgically with laparotomy, resulting in significant improvement, and was scheduled for follow-up to evaluate the feasibility of reintroducing anticoagulation therapy.

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...
