Ulcerative colitis (UC) is a chronic inflammatory disease of the intestine that affects the large intestine and rectum. Although medications and lifestyle changes are often used to treat the disease, severe cases may require surgical intervention. Invasive operations, such as colectomy, widely used in patients with severe or uncontrollable UC, can have a profound impact on various physiological systems, including the hemostasis system. This article aims to study the impact of invasive surgery on the hemostasis system in patients with ulcerative colitis, focusing on the involved mechanisms, possible complications, and methods of postoperative management to reduce risks.
